Moreover, since the chemical treatment equipment is fixed in the factory, depending on conditions such as location, the distribution route for wood usually becomes as follows, for example.

For example, a sawmill operator or a wood supplier requests a chemical treatment company to treat wood with a chemical liquid.

Upon receiving the request, the chemical treatment company performs chemical treatment on the wood. Next, a construction company or a carpenter picks up the chemically treated wood from the chemical treatment company and transports it to the construction site. There are various ways in which this wood can be routed, but in any case, in order to prepare chemically treated wood for the construction site, there is a need for a lumber manufacturer, a chemical treatment company, a construction company, a carpenter, etc. This has the problem of having to go through a distribution channel, which requires a lot of labor, and requires additional transportation costs for the lumber, leading to an increase in construction costs.

The wood accommodating means 1 for accommodating the wood 10 includes a base 6, a sheet floor member 4 formed on the base 6 and constituting a wood placement section on which the wood 10 is placed, and a flexible sheet member 5 that covers the wood 10. and sealing means 18 and 19 for sealing the peripheries of the sheet floor member 4 and the flexible sheet member 5. Furthermore, a pipe blind made of a pipe 9 provided with a through hole is arranged between the flexible sheet member 5 and the wood 10 constituting the wood storage means.

In this chemical treatment apparatus for wood, the sheet floor member 4 and flexible sheet member 5 constituting the wood storage means are formed in a structure that allows them to be transported, stored, etc. in a small folded state, that is, in a crushed state. . A polychloride film or sheet of material that is crushable and impermeable to fluids, has high tensile strength, is strong against bending, is flexible, and is impermeable to air and water. Manufactured from materials such as vinyl. This material is rich in bursting strength, tensile strength, bending strength against bending, repeated strength against tearing force, puncture force, etc., chemical resistance against the chemicals used, and weather resistance against sunlight and solar heat. Of course, it is preferable. Alternatively, the wood placing portion on the base 6 may be placed on the sheet floor member 4.
For example, it may be constructed from a material such as a waterproof concrete body installed at the site, a resin mortar pasted on the concrete, or it may be constructed from a plate member such as an RR board. Of course, this is a good thing.

To place the wood 10 in the wood storage means 1, for example,
A base 6 made of concrete or the like is prepared at a construction site, wood processing site, etc. Of course, a bank portion 32 may be formed around the base 6 for safety to prevent the chemical solution from leaking to the outside. This base 6
A sheet floor member 4 made of chemical-resistant resin mortar, waterproof mortar, or hard polyvinyl chloride is laid on top,
Next, the wood 10 to be treated with a chemical solution is sequentially stacked and arranged with a plurality of spacers 31 made of metal rods, ronds, blocks, etc. interposed therebetween. After the wood 10 is loaded on the sheet floor member 4, in order to prevent the wood 10 from floating due to the chemical solution and to prevent the wood 10 from moving relative to the base member 6, for example, although not shown, The wood 10 is fixed to anchors provided on the base 6 and the seat floor member 4 with lobes or the like to prevent the wood 10 from moving due to floating caused by the chemical solution. Next, the exposed surface of the wood 10 is covered with a pipe group formed into a block of pipes 9 made of chemical-resistant polyvinyl chloride or the like and provided with a large number of through holes. After the wood 10 is covered with a pipe group, the pipe group is covered with a flexible sheet member 5 and sealed with a sealing means provided around the sheet floor member 4 and the flexible sheet member 5.

The sealing means may be, for example, as shown enlarged in FIG.
Consists of a soft rubber plate 18 with rubber or plastic magnets embedded around the periphery of the flexible sheet member 5, and a hard polyvinyl chloride plate 19 with embedded magnets around the seat floor member 4. has been done. Therefore, when the hard polyvinyl chloride plate 19 of the seat floor member 4 and the soft rubber plate 18 of the flexible sheet member 5 are brought into contact with each other, they are strongly attracted by magnetic force, and the sheet floor member 4 and the flexible The contact portion with the sheet member 5 is completely hermetically sealed. In this case, it is also possible to reliably achieve a sealed state by applying or injecting grease, water-soluble glue, or the like to the contact surfaces between the sheet floor member 4 and the flexible sheet member 5. Alternatively, as the sealing means, a pressure-tight airtight fastener (see reference numeral 36 in FIG. 7), which will be described later, may be provided on the seat floor member 4 and the flexible sheet member 5, so that the two can be sealed against each other. .

In this wood chemical treatment apparatus, the wood storage section is formed by the flexible sheet member 5 and the sheet floor member 4 that constitute the wood storage means 1 with the above-described configuration. The flexible sheet member 5 is provided with an air vent 23 for sucking the air inside the wood storage section to create a negative pressure inside the wood storage section, and a chemical solution port 21 for injecting a chemical solution into the wood storage section at appropriate locations. and is formed to a predetermined size. Furthermore, in order to inject the chemical liquid supplied from the chemical liquid tank 8 by the chemical liquid pump 7 into the wood storage section, a chemical liquid population 2 is installed, although not shown.
1 to l! J fog nozzles can also be provided.

Further, the sheet floor member 4 is provided with a chemical outlet 22 having a predetermined size and at an appropriate location for removing liquid from the wood storage portion. Although not shown, it is of course possible to form a chemical outlet 22 in the flexible sheet member 5.

Furthermore, an air vent 23 formed in the flexible sheet member 5
A suction passage 29,30 communicating with the vacuum pump 2 is connected thereto. A sensor 17 is installed near the chemical outlet 22 of the flexible sheet member 5 or inside the buffer tank 3 to detect the amount of the chemical. A buffer tank 3 for air buffering is provided in the suction passage 29, and an on-off valve 15 is provided in the suction passage 30 on the downstream side of the buffer tank 3. This opening/closing valve 15 may be configured as a three-way switching valve. When the on-off valve 15 is configured as a three-way switching valve, when the vacuum pump 2 is operated to suck air from the wood storage section, the buffer tank 3 and the vacuum pump 2 are communicated and the atmosphere side is closed. Also, when the buffer tank 3 side is closed in order to stop the operation of the vacuum pump 2 and maintain the buffer tank 3 side in a negative pressure state,
The vacuum pump 2 side can be configured to be open to the atmosphere.

With this configuration, backflow of oil from the vacuum pump 2 can be prevented. Alternatively, the buffer tank 3 side can be opened to the atmosphere, in which case the wood storage section is opened to the atmosphere, and the chemical solution pump 7 is operated to facilitate recovery of the chemical solution from the wood storage section to the chemical solution tank 8. I can do it. This buffer tank 3 functions as a liquid buffer when the chemical solution is injected into the wood storage section, and also functions as a level gauge for visual inspection of the chemical solution in order to prevent the chemical solution from flowing into the vacuum pump 2 side. For example, when it is detected that the chemical solution has risen, the vacuum pump 2 is
By closing the on-off valve 15 provided in the suction passage 29 in the example, it is possible to prevent the chemical liquid from flowing into the vacuum pump 2 through the suction passage 29. A reduced pressure state is maintained with the wood 10 immersed in the chemical solution. Close the on-off valve 12,
The opening/closing valve 15 is opened, the chemical solution is circulated w1'Ifrt, and if the chemical solution decreases, the chemical solution is replenished.

In this wood chemical treatment apparatus, the chemical supply/recovery system is configured as follows, for example.

That is, a chemical solution supply passage 28, which is a chemical liquid passage incorporating an on-off valve 13, is connected to the chemical liquid port 21 formed on the flexible sheet member 5. This chemical liquid supply passage 28 is connected to the chemical liquid passage 26 on the outlet side of the chemical liquid pump 7. Further, a chemical liquid recovery passage 24, which is a chemical liquid passage incorporating an on-off valve 11, is connected to a chemical liquid outlet 22 formed in the seat floor member 4. This chemical liquid recovery passage 24 is connected to a chemical liquid passage 33 on the inlet side of the chemical liquid pump 7, and it is preferable that a filter (not shown) is provided in the chemical liquid recovery passage 24 to filter the chemical liquid when recovering the chemical liquid. The filter may be provided with a sensor (not shown) to indicate clogging. Further, a chemical liquid supply passage 25, which is a chemical liquid passage connected to the chemical liquid tank 8 and incorporating an on-off valve 12, is connected to a chemical liquid passage 33 on the inlet side of the chemical liquid pump 7. A chemical liquid recovery passage 27 , which is a chemical liquid passage connected to the chemical liquid tank 8 and incorporating an on-off valve 14 , is connected to a chemical liquid passage 26 on the outlet side of the chemical liquid pump 7 .

Furthermore, as for the chemical liquid to be impregnated into the wood 10, boric acid can be used as the least toxic among antiseptic and insect repellent chemical liquids, but it is of course possible to use the following chemicals, for example: It is. In general, wood treatment chemicals used to treat wood to prevent rot, insects, termites, and mildew include copper naphthenate, zinc naphthenate, organic phosphorus compounds (sumithion, phoxim), and pyrethroid compounds. (Permethrin, Exmin), organic iodine-based IF-1000, etc. In addition, although the above example describes the treatment of impregnating wood with a chemical liquid, liquid substances equivalent to chemical liquids, such as resin materials before hardening that are impregnated into wood to modify the wood, can also be applied to this wood. Of course, it is possible to apply the chemical liquid processing apparatus. It goes without saying that in chemical treatment, safety must be kept in mind, and the treatment location is also limited for safety reasons.

The liquid impregnation treatment apparatus for objects to be impregnated according to the present invention is a type of vacuum bank type, that is, a vacuum type impregnation liquid treatment apparatus, and the equipment is extremely simple and lightweight, the impregnation liquid treatment work is easy, and the cost is low. In addition, it is compact and requires a small installation area.For example, depending on the type of chemical, chemical treatment of wood can be performed anywhere, and can be easily used at construction sites. That is,
Places where wood is ultimately used, sawmills (workplaces that process lumber into square timbers and boards into commercially acceptable dimensions), wood chemical treatment workers' workshops, lumber dealers' workshops, builders' workshops, carpenter's cutting workshops, construction sites, etc. This wood chemical treatment device can be easily transported by truck or the like and installed at a site or the like.

Furthermore, the apparatus for liquid impregnation treatment of objects to be impregnated according to the present invention can be modified in design in various respects. In the wood chemical treatment apparatus shown in FIG. As shown in the figure, it is of course possible to set it on the sheet floor member 4 inside the bank portion 32.

In the wood chemical treatment apparatus of each of the above embodiments, the bank part 32 is provided for safety in case of chemical leakage, but in some cases, as shown in FIG. Even if a seal portion is provided around the periphery of the seat floor member 4 disposed in the seat floor member 4, the same function as described above can be achieved. In this chemical treatment device for wood, an example is shown in which a spray nozzle 35 is provided at the chemical supply site. Flexible sheet member 5
By providing the spray nozzle 35 in the chemical solution port 21 provided in the chemical solution port 21, the chemical solution injected into the wood storage section formed of the flexible sheet member 5 can be brought into contact with the wood 10 in a sprayed state.

Although not shown, the flexible sheet member 5 may be provided with a negative pressure release valve for releasing the negative pressure inside the wood storage section. It goes without saying that it may be configured to operate not only to remove the chemical liquid and collect it in the chemical liquid tank 8, but also to circulate the chemical liquid to the wood storage section. Furthermore, although the vacuum pump 2, chemical liquid pump 7, and chemical liquid tank 8 are shown installed at the site, it goes without saying that they may remain mounted on an equipment transport vehicle such as a trunk or a trailer. Further, although not shown, the wood storage section formed by the wood storage means is formed in a state that can be sealed with a sealing means. Of course, it may be configured as follows.

Next, a description will be given of a wood chemical liquid treatment control apparatus for chemically treating wood 10 when the liquid impregnation treatment apparatus for an object to be impregnated according to the present invention is applied to the chemical liquid treatment of wood.

In this wood chemical treatment control device, a sensor 16 detects the air pressure inside the wood storage section formed by the flexible sheet member 5 and the sheet floor member 4, and a sensor detects the amount of the chemical solution supplied into the wood storage section. 17, and a sensor 34 for detecting the amount of the chemical solution for detecting whether the chemical solution in the wood storage section has been collected into the chemical solution tank 8. Depending on the case, a level sensor may be provided in the wood storage section to detect the amount of chemical liquid impregnated into the wood 10 and to check the amount of chemical liquid used, and a level sensor may be installed in the wood storage section to indirectly detect the amount of chemical liquid used. 8 may be provided with a level sensor. Furthermore, the sensors 16,17 can be installed in any suitable location, and are shown in the buffer tank 3. These sensors 16,
The detected fε number of 17.34 is input to the controller 20. Controller 20 has sensors 16.17.34
In response to each detection signal, each opening/closing valve 11, 12°1
3.14.15, issues an opening/closing command to control the opening/closing of each of the on-off valves, and also issues a command to the vacuum pump 2 and chemical pump 7 to control on/off of the vacuum pump 2 and chemical pump 7. conduct.

In addition, in the chemical treatment of the wood 10, some chemicals require temperature adjustment. In that case, although not shown, the seat floor member 4 and the flexible seat member 5
A temperature sensor can also be provided to detect the temperature in the wood receptacle formed by the

In addition, in this wood chemical treatment control device, when impregnating wood with a chemical, after the wood is completely immersed in the chemical, the vacuum pump 2 is used to move the inside of the wood storage part within the range that does not cause liquid leakage from the sealing part. It is preferable to reduce the degree of depressurization, bring the degree of vacuum closer to atmospheric pressure than the initially set vacuum level, and inject the chemical solution into the wood storage section under slight pressure.
Controls the degree of opening and closing of the on-off valve 13 and the like.

(Hereinafter, the margin of this page) Next, an example of the operation of the chemical liquid treatment control device when the liquid impregnation treatment control device of the present invention is applied to the chemical treatment of wood is shown in Fig. 6 (A). , Figure 6(B) and Figure 6
This will be explained with reference to the processing flow diagram shown in FIG.

First, a chemical treatment device for wood transported to a location such as a construction site or a wood processing site is assembled, and the sheet floor member 4 is laid on the base 6.
has already been fixed. Predetermined pieces of wood 10 to be treated with a chemical liquid that have been transported to the site are stacked on the sheet floor member 4.
The wood IO is sequentially stacked with a plurality of spacers 31 interposed therebetween so that the wood 10 is sufficiently impregnated with the chemical solution from the entire surface of the wood IO. After a predetermined amount of wood 10 is stacked, the wood 10 is fixed to an anchor provided on the base member 6 using a lobe or the like, for example, to prevent it from floating due to the chemical solution or making the stacked state unstable. In some cases, it is of course possible to interpose a support or the like to restrain the movement of the wood 10 or to install the base member 6 upright in advance. A blind is hung and covered with a flexible sheet member 5. Flexible sheet member 5
The edge of the soft rubber Fi1 provided on the flexible sheet member 5
Hard polyvinyl chloride 119 provided with 8 on the seat floor member 4
The edge of the flexible sheet member 5 and the edge of the sheet floor member 4 are completely sealed. By these operations, preparations for the chemical treatment of the wood 10 are completed.

First, the on-off valve 11, 1213.1 provided in the chemical liquid passage
4 is closed according to a command from the controller 20 (step 40), and the on-off valve 15 provided in the suction i passage 29 is closed.
is opened by a command from the controller 20 (step 41), and in this state, the vacuum pump 2 is turned on by a command from the controller 20.

In step 42), air is sucked from the wood storage section formed by the sheet floor member 4 and the flexible sheet member 5 to create a negative pressure inside the wood storage section. 1 after a predetermined period of time preset by a timer has elapsed.

(Step 43), the sensor 16 detects the pressure P in the wood storage section, and inputs the detection signal to the controller 20 (Step 44).
A pressure P0, that is, a negative pressure state, which is the most preferable state for impregnating the wood 10 in the wood storage section with a chemical solution, is set.

Therefore, the comparator of the controller 20 compares and determines the predetermined pressure P0 and the detected pressure P (step 45).

The detected pressure P is smaller than the predetermined pressure P0 (P.

>p>, the process proceeds to step 50, but if the detected pressure P does not become smaller than the predetermined pressure P, the number of comparison judgments N is counted (step 46).
, the count is performed after a predetermined time t preset by the timer has elapsed (step 48), and although the vacuum pump 2 is operating, the inside of the wood storage section does not reach a predetermined level even after a predetermined number of times, for example, N=4. If the pressure does not become smaller than P0 (step 47), the operation of the vacuum pump 2 itself is defective, the sealing portion between the seat floor member 4 and the flexible sheet member 5 is defective, or the flexible sheet Since there is a possibility that an abnormal situation such as the member 5 is torn has occurred (step 49), in order to inspect the chemical processing system, the operation of the vacuum pump 2 is turned off and stopped, and the processing ends. After inspecting and repairing the abnormal location, the process returns to step 40 to control the chemical treatment of the wood 10.

In step 45, the detected pressure P reaches a predetermined pressure P.
When the pressure becomes smaller than 0 (Pa>P) and a favorable negative pressure condition is established to impregnate the chemical solution into the wood 10, the opening/closing valves 12 and 13 of the chemical solution passage are opened in order to inject the chemical solution into the wood storage section (step 50). .

When the interior of the wood storage section becomes negative pressure, the wood 1
0 is placed, and the flexible sheet member 5 receives atmospheric pressure from the outside and is pressed against the pipe blind made up of a large number of pipes 9.

At this time, the operation of the vacuum pump 2 continues (. Then,
The chemical liquid pump 7 is turned on and operated, and the chemical liquid in the chemical liquid tank 8 is transferred from the chemical liquid population 21 into the wood storage section through the chemical liquid supply passage 25 - chemical liquid passage 33 - chemical liquid pump 7 - chemical liquid passage 26 - chemical liquid supply passage 28. A medical solution is injected into (step 51). The chemical solution injected into the wood storage section is in a state where it easily permeates into the wood 10 placed in the negative pressure state S, and the chemical solution smoothly permeates into the wood 10. After the predetermined time set by the timer T
, (step 52), the sensor 17 detects the amount of chemical liquid injected into the wood storage section, and inputs the detection signal to the controller 20 (step 53).This sensor 17, for example, as shown in the figure, This is a level sensor or the like provided in the buffer tank 3 or near the air vent 23 formed at the top of the flexible sheet member 5, and the sensor 17 can detect the amount of the chemical solution.

The amount of chemical solution is injected into the wood storage section until the wood 10 is completely immersed. Once the wood 10 is impregnated with the chemical solution and the level of the chemical solution drops, the chemical solution is injected into the wood storage section. For example, if the chemical solution rises to the suction passage 29 connected to the air vent 23, the amount of the chemical solution at that time becomes the predetermined chemical amount V0 when performing chemical treatment on the wood 10.
In this case, a level sensor may be provided to detect the water level of the chemical liquid in the chemical liquid tank 8, and the level sensor may be configured to detect the amount of the chemical liquid used.

Next, the comparator of the controller 20 compares and determines the detected amount V of the chemical solution with a predetermined amount v0 set in advance (step 54), and determines whether the detected amount V of the drug solution is greater than the predetermined amount V0 of the drug solution. When (V>V,), the process proceeds to step 59, but if the detected chemical solution 1v is not greater than the predetermined amount V, the number of times n of comparison judgments is counted (step 55), and the count is This is performed after a predetermined time period t□ previously set by a timer has elapsed (step 57). Although the chemical liquid pump 7 is operating, if the amount of chemical liquid in the wood storage section does not increase to more than the predetermined chemical liquid 11v even after a predetermined number of times, for example, n=3, (step 56)
, the operation of the chemical liquid pump 7 itself is defective, the seal between the sheet floor member 4 and the flexible sheet member 5 is defective, or the sheet floor member 4 or the flexible sheet member 5 is torn, causing the chemical liquid to leak out. There is a possibility that the liquid has leaked to the outside, or that an abnormal situation has occurred in the chemical liquid passage system, etc. (Sten 158)
Therefore, in order to inspect the chemical processing system, the chemical pump 7 and vacuum pump 2 are turned off and stopped, and the on-off valves 12 and 13 are closed to complete the process.Next, after inspecting and repairing the abnormality, , go back to step 40 and add 10 pieces of wood.
Chemical liquid processing control is performed.

In step 54, when the detected chemical liquid amount ■ becomes larger than the predetermined chemical liquid amount v6 (V>Va) and becomes a good chemical liquid amount V that impregnates the wood 10 with the chemical liquid, the inside of the wood storage section has a sufficiently good negative pressure P. , the vacuum pump 2 is turned off to stop the air suction operation (step 59).Next, the on-off valve 15 provided in the suction passage 30 is closed (
Step 60) When the vacuum pump 2 is stopped, the on-off valve 15 provided in the suction passage 30 is switched to maintain negative pressure on the buffer tank 3 side so that the lubricating oil of the vacuum pump 2 itself does not flow back into the suction passage 30. , open the vacuum pump 2 side to the atmosphere. In some cases, an on-off valve 15 may be provided in the suction passage 30.
Another opening valve may be provided on the downstream side of the vacuum pump 2 to prevent the lubricating oil of the vacuum pump 2 itself from flowing back into the suction passage 30 by opening the opening/closing valve. Also, in some cases, at this time, the sensor 16 may be removed without opening the vacuum pump 2 to the atmosphere.
It goes without saying that the vacuum pump 2 may be activated so that the atmospheric pressure inside the wood storage section detected by is maintained at a predetermined reduced pressure state B.

By the way, depending on the type of wood 10 and the type of chemical, forced circulation of the chemical may be preferable for impregnating the wood 10 with the chemical. Therefore, the above-mentioned conditions are input into the controller 20 in advance, and it is then determined whether or not to forcefully circulate the chemical solution into the wood storage section (step 61). When forcing the chemical solution into the wood storage section, the controller 20
The on-off valve 1 installed in the chemical liquid recovery passage 24 according to the command of
1 (step 62), and open/close valve 12.
(step 63), whereby the chemical solution in the wood storage section is transferred to the wood storage section chemical solution outlet 22 - chemical solution recovery passage 24 - chemical solution passage 33 - chemical solution pump 7 - chemical solution passage 26 -
A forced vFi connection is made through the chemical solution supply passage 28 and the chemical solution port 21 to the wood storage section. After a predetermined time period preset by the timer has elapsed, the process returns to step 61 at Ts (step 64). In this case, if a filter is provided in the chemical solution recovery passage 24, IJI may be used to detect whether or not the filter is clogged.
If the filter becomes clogged due to the detection signal,
It goes without saying that the process may be temporarily interrupted and a warning or display may be issued to request cleaning of the filter.

Next, in step 6I, if there is no need to forcefully circulate the chemical solution to the wood storage section, the operation of the chemical solution pump 7 is stopped (step 65), and the on-off valves 12 and 13 are closed (step 66). In this state, the time T4 is preset by the timer manually input to the controller 20.
(For example, leave the wood immersed in the chemical solution for a period of 3 hours (step 67). Normally, the chemical solution is injected into the wood container in anticipation of the amount of the chemical solution that will impregnate the wood 10. In some cases, a sensor 17 is set in the wood storage section, and when the sensor 17 detects that the wood 10 has been impregnated with a chemical solution and the level of the chemical solution has dropped, the on-off valve 12 and the on-off valve 13 are turned on. When the pressure inside the wood storage section exceeds a predetermined range, the on-off valve 15 is opened and the vacuum pump 2 is operated to release the wood. Control is performed to maintain a predetermined negative pressure inside the housing.

After the wood 10 is impregnated to a predetermined depth with a predetermined amount of the chemical liquid, the on-off valve 11 provided in the chemical liquid recovery passage 24 and the on-off valve 14 provided in the chemical liquid recovery passage 27 are opened (Step 68), and the chemical liquid pump 7 (Step 69), whereby the chemical solution in the wood storage section is transferred from the chemical solution outlet 22 of the wood storage section to the chemical solution recovery passage 24 to the chemical solution passage 3.
3-Medical liquid pump 7-Medical liquid passage 26-・Medical liquid recovery passage 27
The chemical liquid is collected through the chemical tank 8. TS after a predetermined time preset by the timer (Step 7
0), the sensor 34 detects a state in which the chemical solution is discharged from the wood storage section (step 71). When the sensor 34 detects that the chemical solution is discharged from the wood storage section, the detection signal is sent to the controller. 2o. Upon receiving the detection signal, the controller 2o issues a signal to turn off the chemical liquid pump 7, and stops the operation of the chemical liquid pump 7 (step 72).
1 and the on-off valve 14 are closed (step 73), and the operation control of the chemical treatment on the wood 10 is completed.

Next, if the wood 10 is left as it is, the chemical solution impregnated into the wood 10 will spread and penetrate into the wood.Then, the flexible sheet member 5 and pipe blind covering the wood 10 will be removed, and the wood 10 will be removed. Leave it as it is and air dry the wood 1o. Next, by taking out the wood 10 from the sheet floor member 4, the chemical treatment on the wood 10 is completed.

This wood chemical treatment control device can incorporate an emergency operation stop control device.

That is, in this wood chemical treatment system 2, during operation, for example, the chemical tank 8 is filled by the operation of the chemical pump 7.
When the chemical solution is injected into the wood storage section, during forced circulation of the chemical solution, or when the chemical solution is left in the wood storage section, the flexible sheet member 5 may be torn or damaged. When the sealing condition between the flexible sheet member 5 and the sheet floor member 4 becomes poor and a phenomenon occurs in which the chemical liquid flows out from the wood storage section, these abnormal conditions are detected by the sensors 16 and 17. By manually inputting the detection signal to the controller 20, the emergency operation stop control device is activated and the operation control of the chemical liquid processing is stopped. For example, each sensor 1 measures the pressure P and the amount of chemical liquid in the wood storage section.
6.17, the detection is always performed and each detection signal is input to the controller 20. If an accident occurs during operation and the pressure P and chemical liquid amount V in the wood storage section suddenly deviate from the predetermined range, an alarm will be issued, the vacuum pump 2 and the chemical liquid pump 7 will be stopped, and the opening/closing operation will be activated. The valves 11 and 13 are closed to stop the operation, so that abnormalities can be inspected.

Above, an embodiment has been described in which the liquid impregnation treatment apparatus for an object to be impregnated and its control apparatus according to the present invention are applied to the chemical liquid impregnation treatment of wood. However, the present invention is not limited to the above-mentioned embodiment. As shown in FIG. 7, an apparatus for liquid impregnation treatment of an object to be impregnated according to the present invention may be configured.

Referring to FIG. 7, another embodiment of the apparatus for liquid impregnation of an object to be impregnated according to the present invention will be described. This embodiment has exactly the same tJITli, as compared to the above embodiments, except for the structure constituting the wood storage means l, and therefore, the structure shown in FIG. The same parts as those in the wood chemical treatment apparatus are given the same reference numerals and redundant explanations will be omitted.

Further, this wood chemical treatment device can operate as a chemical treatment control device similar to that described above, and the chemical treatment control device is also completely the same as that of the above embodiment.

In the wood chemical treatment apparatus shown in FIG. 7, the wood storage means 1 is comprised of a container 35 made of a flexible sheet material. The structure of this container 35 is such that it can be transported, stored, etc. in a small folded state, that is, in a crushed state, and the shape of the container 35 is as shown in FIG. 8 or 9. , a sealable wood doorway 38 consisting of a container or bag in the form of a sheet or bag. When the container 35 is used in this wood chemical treatment equipment, the equipment is extremely simple and lightweight;
The chemical treatment work is easy, the cost is low, and it is compact and the installation area of the device itself is small.Furthermore, depending on the type of chemical, the chemical treatment of wood can be performed anywhere. Can be easily used at construction sites 0 For example, this wood chemical treatment equipment can be easily transported and installed by truck etc. at the final use site of the wood, sawmill, wood chemical treatment workshop, construction site, etc. can do.

The container 35 is made of a material that is crushable and impermeable to fluids, has high tensile strength, is strong against bending, is flexible, and is impermeable to air and water. Manufactured from film or sheet material. The film used to make the container 35 has burst strength against tearing force, puncture force, etc., tensile strength, bending strength against bending, repeated strength against these, chemical resistance against chemicals used, and weather resistance against sunlight and solar heat. Of course, it is preferable to use such a material. The material of this container 35 is, for example, a film thickness of 0.6 to 1,
Using a film of Qmm, it can be manufactured in the form of a large Boston bag, as shown in FIG. Further, as shown in FIG. 9, the container 35 is constructed by bonding the lower edge of the large Boston bag to a metal plate 37 with an adhesive or the like.
It is also possible to configure and form the bottom part of. Specifically, the container 35 is made of a synthetic rubber film reinforced with Tetron cloth, and the film has a thickness of 0.8 fi.
This film is manufactured by bonding the film with an adhesive to a structure as shown in FIG. 8 or 9.

Furthermore, in order to put the wood 10 into and take out the container 35, the container 3
5 is provided with a wood entrance/exit 38 which extends from the side surface in the longitudinal direction through the upper part to the other side surface. When the wood doorway 3, which is shaped like a container 35, is opened, the wood 10 is placed in the container 3.
It is expanded to a size that makes it easy to store it in the container 5 or take it out from the container 35. Also, container 35
In order to maintain a negative pressure state inside the container 35 or to prevent leakage of the chemical solution when it is injected into the container 35, it is used, for example, as a diving suit fastener, etc. at the wooden entrance 38 formed in the container 35. A pressure-resistant airtight fastener 36 such as the one shown in FIG. That is, since the container 35 is used in a negative pressure state or in a state filled with a chemical solution, it must be constructed in a sealed structure.There are various methods of sealing, but an airtight fastener with pressure resistance specifications can be used to seal up to ±1 atmosphere. It is preferable to use one with the following specifications.

Furthermore, the internal volume of the container 35 is reduced due to negative pressure, and there are parts where the film comes into close contact with the surface of the wood 10 stacked in the container 35, and there are also parts where it does not come into contact with the wood 10. , the surface of the container 35 becomes uneven. Even in such a case, the film forming the container 35 needs to have the strength to withstand the negative pressure in the areas where the wood 10 does not come in contact with. It must withstand bursting forces caused by pressure. Therefore, between the inside of the container 35 and the wood IO, a pipe group consisting of the pipe 9 as shown in the figure, a vinyl or plastic net in the form of a mesh, a coarse woven fabric, etc. are arranged, and the wood is If the film in the form of a container 35 is made to wrap around the entire deposit or the irregularities of the wood IO and adhere tightly to this net during negative pressure, the strength of the film can be reinforced, and the strength of the film can be improved. is completely safe and the container 35 can be used repeatedly over a long period of time.

Alternatively, the liquid impregnation treatment apparatus for an object to be impregnated according to the present invention includes:
As shown in FIG. 10, the present invention can be applied not only to the chemical treatment of wood as described above, but also to the peeling treatment of citrus fruits such as tangerines, oranges, and grapefruits. In this example, compared to the example described with reference to FIG. 7, 1 degree of wood is treated, whereas 39 pieces of citrus fruit are vacuum impregnated with an aqueous food enzyme solution to remove pulp and peel. This is applied to the process of separating . Therefore, the liquid impregnation treatment apparatus itself for the object to be impregnated has exactly the same configuration as that shown in FIG. 7, and therefore, the same parts as in the embodiment shown in FIG. Therefore, duplicate explanations will be omitted. In addition, the peeling process of citrus fruits using food enzymes can be operated as a liquid impregnation process control apparatus in the same way as described above, and since the explanation of the liquid impregnation process control apparatus is redundant, this explanation will also be omitted.

In this liquid impregnation processing device for the object to be impregnated, in order to vacuum impregnate the aqueous solution of pectinase, which is a degrading enzyme, between the peel and pulp of the citrus fruit 39, first, one or more thin incisions are made in the peel of the citrus fruit 39. Put in. A citrus fruit 39 with a cut in the skin is packed into a container 35. As in the case of wood, the pressure inside the container 35 is reduced, and an aqueous solution of pectinase, which is a degrading enzyme, is injected into the container 35, and the enzyme is used to separate the skin and pulp. Allow it to soak in thoroughly during this period. Peeling can be done very easily by allowing the fruit to stand for several hours and then peeling the skin from the pulp.

Here, the container 35 was used to peel the citrus fruits, but as shown in FIG. 39 can also be treated with a large amount of impregnating liquid.

(Effects of the Invention) The liquid impregnation treatment apparatus for objects to be impregnated and its control apparatus according to the present invention are configured as described above, and have the following effects.

The liquid impregnation treatment apparatus for an object to be impregnated according to the present invention includes: an object to be impregnated storage means capable of accommodating an object to be impregnated and an impregnating liquid; a vacuum pump that sucks gas from the inside of the object to be impregnated through a suction passage; An impregnating liquid tank communicating with the impregnating object storage means through an impregnating liquid passage, a pump for injecting or recovering the impregnating liquid into the impregnating object storing means, and each valve provided in the impregnating liquid passage and the suction passage. Since I configured it,
Materials to be impregnated, such as wood and citrus fruits, are transported to construction sites, treatment sites, etc., and transported to large-scale processing plants, where the materials to be impregnated are treated with preservatives, fungicides, insect repellents, and 8! It is possible to impregnate the impregnated object with a chemical solution such as F.I.T. The material to be impregnated stored in the material storage section is placed in a negative pressure, in other words, in a vacuum bank atmosphere, and the inside of the wood or between the peel and pulp of the citrus fruit is placed in a negative pressure state, and the chemical solution is added to the material to be impregnated. By creating a state in which the impregnation of enzymes, etc. can easily permeate, and injecting the impregnating liquid into the impregnated object storage section, the impregnating liquid is sucked into the impregnated object under negative pressure and penetrates smoothly, impregnating it into the impregnated object. The liquid is fully impregnated. Moreover, the operation is simple and the device itself can be manufactured at low cost, and at the same time, the impregnating effect of the impregnating liquid on the object to be impregnated is reliable and highly reliable.

Further, the impregnated object storage means includes a heath, an impregnated object placement part formed on the base, a flexible sheet member that covers the impregnated object, and the impregnated object si placement part and the flexible sheet member. The flexible sheet member and the sheet floor member constituting the object storage section for storing the object to be impregnated can be folded down to make it smaller and can be used at construction sites, etc. as desired. It can be easily transported to the site, quickly and easily assembled and installed at the site, and equipment such as pumps can be easily transported to the site.
It can be easily assembled and installed at the site, and the object to be impregnated can be treated by storing the object in the object storage section and impregnating the object with the chemical solution easily on the site by operating the vacuum pump and the pump. can. In addition, since the impregnated material storage means itself is formed from a thin sheet rather than a regular container,
When the inside of the impregnated object storage section becomes negative pressure, it is pressed against the stacked objects to be impregnated, and the wasted space in the place where the impregnated object storage means is installed is minimized, and the capacity of the vacuum pump can be reduced to a small capacity. Furthermore, the required amount of impregnating liquid to be injected into the impregnated object storage section is equal to i3! This is the amount to be filled into the gap between the object to be impregnated and the sheet forming the container, and the gap between the objects to be impregnated, and only a very small amount is required. Moreover, after the impregnation process with the impregnating liquid is completed, the sheet that makes up the floor surface
It is possible to easily wash and clean the impregnated object placement portion such as the floor member, the flexible sheet member constituting the upper surface, and the like. In this case, if the washed waste liquid is collected in a waste liquid recovery device, it is possible to perform treatment that is preferable from the viewpoint of hygiene and safety.

In addition, since a pipe group consisting of a pipe with a through hole is arranged between the flexible sea member and the impregnated object,
When the impregnating liquid is injected into the object storage section, the impregnating liquid can move smoothly between the flexible sheet member and the object, and the impregnating liquid can be uniformly impregnated from the entire surface of the object. liquid can be impregnated.

Alternatively, in this apparatus for liquid impregnation of an object to be impregnated, the object to be impregnated may include a container, the container being made of a material that is impermeable to the impregnating liquid and crushable, and the object to be impregnated can be sealed. Since it is equipped with an entrance and exit, the equipment is extremely convenient and lightweight, the liquid impregnation process is easy, the cost is low, and the equipment itself is compact and requires a small installation area. Furthermore, depending on the type of impregnating liquid, the liquid impregnation treatment of the object to be impregnated can be performed at any work location, and can be easily used at construction sites, citrus processing sites, and other locations. For example, the container and the liquid impregnation treatment apparatus can be easily transported by truck or the like and installed at a site or the like.

Alternatively, the liquid impregnation processing control device for an object to be impregnated according to the present invention includes an object to be impregnated storage means capable of accommodating an object to be impregnated and an impregnating liquid, a vacuum pump that sucks gas from inside the object to be impregnated means, and the object to be impregnated. an impregnating liquid tank communicating with the impregnating material storage means;
A pump for injecting or recovering the impregnating liquid into the impregnating object storage means, each valve provided in the impregnating liquid passage and the suction passage,
A sensor that detects the internal pressure, a sensor that detects the amount of impregnating liquid in the object storage means, and a sensor that controls the opening and closing of each valve in response to each detection signal from each sensor, and Since it is composed of a controller that controls on/off of the pump, all you have to do is install the liquid impregnation treatment device for the object to be impregnated at a predetermined location and load the object to be impregnated, and the subsequent processing work can be done automatically. can. Therefore, just by monitoring by one worker, several hours or tens of hours of work can be accomplished without requiring any effort.

Furthermore, the negative pressure within the impregnated material storage area constituted by the flexible sheet member, the sheet floor member or the container does not need to be a high vacuum and therefore may be used in a vacuum state or for filling the impregnating liquid. The sheet member that can withstand the maximum industrial pressure is sufficient for the sheet member to withstand the maximum industrial pressure.Furthermore, the sheet member forming the container can be tightly attached to the outer surface of the pipe group by negative pressure from the state of wrapping the object to be impregnated. Therefore, the volume to be sucked by the vacuum pump is extremely small, and the vacuum pump itself can be extremely small, reducing costs.

As mentioned above, this device itself is compact and has a small installation area, and the container can be transported in a folded state, so it can be used at any work location. However, when a hazardous substance is used in a chemical solution, it is a matter of course that the work location must be regulated in accordance with the Toxic Substances and Deleterious Substances Control Law, and attention must be paid to safety. Therefore, this chemical treatment device can treat the incisions of the wood with chemicals at the carpenter's cutting workshop or at the construction site, after the wood has been cut. It is possible to reliably and sufficiently impregnate the chemical solution even in parts of the wood that are difficult to be sufficiently treated with a chemical solution such as for termite control, ie, wood parts such as wood-to-wood contact points and incisions.
