Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an oil impregnation dryer for dust control products, and more specifically, a series of manufacturing processes for dust control products, including washing, rinsing, dehydration, oil impregnation, and drying. In the drying process, this oil impregnation dryer not only performs the original drying function, but also performs oil impregnation processing as a pretreatment for the drying process, and is capable of controlling the state of oil impregnation throughout the fibers. This relates to an oil impregnation dryer for dust control products that utilizes centrifugal force to ensure uniformity and completeness.

<Conventional technology> Many conventional technologies have been provided for manufacturing dust control products such as motu, mats, and cloth, but in any case, impregnation with oil in the manufacturing process has not been done separately. It was customary to use an independent suction processing machine. In the case of processing using such an adsorption processing machine, the oil is usually sprayed after drying.1 For example, the amount of adsorbent at the tip and surface of the motsup pile tends to become so-called oil-rich, reaching the base. It was difficult to penetrate the oil solution evenly, and it was difficult to penetrate the oil solution evenly. Furthermore, since the oil was sprayed in the form of a mist at the manufacturing plant, the oil would scatter into the air, making it impossible to ensure a sufficient working environment for workers on site. .

A specific example of such conventional technology is the "Oil Spraying Device" (Utility Model Publication No. 40702/1982). In other words, ``The oil spraying device of this invention is equipped with a rotating drum that is driven to rotate, an inlet/outlet hole in the side wall, and a lid body that can seal the inlet/outlet hole, and furthermore, The gist thereof is to include a casing supported tiltably relative to a base, and a spray nozzle for spraying an oil agent into the rotating drum of the casing.

With such a configuration, when spraying the oil onto a rag, the casing, that is, the rotating drum is rotated in a horizontal state, and the oil is sprayed by the spray nozzle. When taking out the rag after spraying, the lid is opened, the casing is tilted, and the rotating drum is rotated, so that the rag is sequentially discharged from the inlet/outlet hole.

<Problems to be Solved by the Invention> However, this technique has a serious drawback in that too much oil is applied non-uniformly only to the tips and surfaces of the fibers such as mops that are to be washed.

However, as can be easily understood by looking at the structure of the device, this technique relies solely on the so-called capillary phenomenon to diffuse the oil agent throughout the fibers. In addition, since the spraying device according to the invention is an independently necessary device whose purpose is only to spray the oil agent, it is necessary to carry out a series of processes necessary for manufacturing dust control products, that is, washing, rinsing, dehydration, etc.・Considering that, there is a large time loss, and problems such as securing space to place the equipment, the need for transportation equipment to the equipment before and after the production line, and securing the personnel for this have been pointed out. was. As described above, in this invention, the oil adsorption processing device was a separate and independent unit, but in the present invention, the structure of the dryer itself has been improved to ensure the original function of the dryer, and at the same time, the oil adsorption processing device has been improved. Since it is used as a device that is also capable of impregnation processing, it is possible to avoid the need for a separate impregnation processing device. In the prior art, the materials to be manufactured are limited, or it is impossible to impregnate large or cloth-like items evenly and completely. However, in the conventional technology, an oil agent was sprayed as an independent separate process after the drying process, which is the final process of manufacturing, but in the present invention, the oil agent is sprayed in a state after dehydration but before drying, that is, after the drying process, which is the final manufacturing process, In the oil-impregnated dryer according to the present invention, an oil is sprayed as a pre-drying treatment, and water and oil are separated by using the centrifugal force generated by the rotation of the drum. This is to ensure uniform and complete impregnation of the oil into the fibers by utilizing the difference in specific gravity. The meaning and rationale for using centrifugal force here is that centrifugal force is used to attach the dehydrated laundry to the side wall of a drum with punch holes for drying, and by spraying oil, it is possible to Eliminates loss of oil through the holes and achieves uniform impregnation, including loosening during normal rotation after spraying has stopped. After that, the process moves on to the drying process, which takes advantage of the fact that the oil adhered to the fibers moves from areas where the concentration is higher to areas where it is more evenly distributed. Note that the oil impregnated dryer in the present invention is generally used as a dryer.

Three methods have been provided: (1) tumbling method, (2) tunnel drying method, and (2) drying chamber method. In the present invention, a dryer employing the tumbling method is used. The drying and tumbling method is based on the fact that the dry state of the fiber after drying is soft, making it possible to remove excess fiber waste, and making it suitable for manufacturing dust control products.

As described above, the present invention provides an oil impregnation dryer that enables an innovative oil impregnation process for improving the working environment, streamlining, and saving labor during the production of dust control products.

<Means for Solving the Problems> The constituent elements of the oil impregnated dryer of the dust control product according to the present invention include a blower operated by the drive of a blower motor, and the blower supplies outside air from an air supply duct. , in a tumbling dryer that exhausts air through the drum and through the exhaust duct and exhaust duct.
A rotatably driven drum is installed inside the outer shell, and a spray nozzle for atomizing oil is provided through either the sealable opening and closing doors on both sides provided on the outer shell or through the shaft, and a spray valve is attached to this spray nozzle. It is an oil impregnated dryer connected via a hose with a heating device), ■
, Oil supply pump from the oil tank, ■, Spray nozzle and spray piping, ■, Device with solenoid valves, flow meters, and sea sensors that control the amount of spray for each product, ■, Drum inside the dryer during oil spraying. (1) A device for controlling the rotation and centrifugal force of the product;

Hereinafter, the present invention having such characteristics will be described in detail with reference to the accompanying drawings.

1 to 3 show an example of an oil impregnated dryer (35) for dust control products according to the present invention. The outer body (2) is equipped with a drum (1) having a large number of punch holes (27) that is rotatably driven. Things to wash (36)
At the stage of charging the cloth into the drum (1), the washing, rinsing, and dehydration processes have already been completed and the cloth is in a state before drying. Therefore, the items to be washed (36) were transferred to the oil-impregnated dryer (
35), and after spraying the oil agent, the items to be washed (36)
As a drying process, the drum (1) of the oil impregnation dryer (35)
), an escape route is required to disperse the moisture impregnated in the item to be washed (36) at that time, so on the surface of the drum (1) set inside the outside 11M (2), A large number of punch holes (25) are formed.

And, on both sides of the outer body (2), there are sealable opening/closing doors (1
5) (17) is provided, and this opening/closing door (15)
(17) is installed with a spray nozzle (29) connected to the port (28), and this spray nozzle (29) may be connected to the opening/closing door (15) (17), It can also be installed via a shaft. Such a spray nozzle (29) is for spraying oil into the drum (1), but as the drum (1) rotates, the article to be washed (36) also rotates. The motsupu etc. that are being manufactured in the drum (1) are transferred to the drum (1).
) may get caught on the protruding part of the spray nozzle (29) (when installing the spray nozzle on an opening/closing door). It is made so that it does not protrude directly inward from the drum (1). Also, spray nozzle (29
) is very important considering the need to spray the oil evenly. Therefore, the spray nozzle (
29), when installing the drum (1), punch holes (
27) Set the position and angle so that it can cover all of the one side wall surface! ! It is effective to set 2. If the angle or position is incorrect, it will be difficult to spray the oil uniformly. This spray nozzle (29) sprays the oil into the oil tank (3), which has a check valve provided to prevent backflow of the oil.
1) is connected to a hose (28) for feeding from.

In the middle of the hose (28), there is a spray valve (a solenoid valve) that is a control valve for adjusting the flow rate of the oil to a specified level.
The other end of the hose (28) provided with the hose (30) is connected to the oil tank (31). This oil tank (3
1) is a tank that stores and holds oil.
Separately, if an automatic liquid level control device is set in the oil tank (31), when the remaining amount of oil gets low, the oil tank (31) can be automatically refilled with a constant amount from the auxiliary tank. (23) is a pump to send out the oil and control the flow rate, and (26) is a pump that maintains the viscosity of the oil at a constant level and stabilizes it even when the location is in a cold region. The preheater (24) is a switching valve for supplying oil;
24) is circulated by the pump (22) while passing through the preheater (26) to prevent the temperature from falling and the amount of sprayed oil from varying or increasing the viscosity of the oil, even if the area is in a cold region. It is a valve to allow The oil temperature control device is set in the preheater (26).

Temperature control is necessary to prevent the viscosity of the oil itself from changing if there is a temperature difference in the oil and to achieve uniformity. Note that (23) is a flow meter for determining and checking a predetermined spray amount for each quality, and (25) is an air tank that functions to send out an accurate amount of oil. In addition, the control panel (32) is
It is used to control the flow rate of oil for each product, determine whether or not oil spray is necessary, and serve as a signal in the event of trouble. Further, (8) is a lint basket that collects thread waste, etc., and (3) is a frame for holding the entire oil impregnated dryer.

The actual production of dust control products using the oil impregnation dryer (36) having such a configuration will be described.

First, as in normal manufacturing, washing, rinsing, and dehydration are performed using a washer-extractor (33), and then the belt conveyor (
34), the object to be washed (36) is transported and placed in the oil impregnating dryer (35) according to the present invention, where it is impregnated with an oil agent and subjected to drying treatment.

The procedure for impregnating with the oil agent in this case will be described later.

Next, the original drying process of the object to be washed (36) in the present invention will be explained. This drying step is performed after the oil agent spraying step using the oil agent impregnating dryer (35) is completed. First, by operating the blower motor (7), the blower (6), which is a blower impeller, rotates.

As a result, fresh outside air is supplied from the air supply duct (21), heated by the steam heater (4), and enters the drum (1), where it is mixed with the items to be washed (36). As a result of the heat exchange, the object to be washed (36) becomes warmer due to the hot air and moisture evaporates, while the hot air flowing into the drum (1) is heated by contact with the object to be washed (36). It gets colder and colder. The air and moisture that have become cold air pass through the lint catcher (8) located at the bottom of the drum (1), the exhaust duct (20), and the exhaust duct (5) to the outside of the dryer (35). is discharged. The rotation of the drum (1) is set by a variable rotation speed drum motor (9) connected via a bell (14).

In the figure, the steam heater (4) and the exhaust duct (5) have a three-dimensional structure. In addition, (12) and (13) are pulleys,
(10) indicates a support roller, and (11) indicates a pillow type bearing. In the present invention, the opening/closing door (15) (17)
Although two new doors are installed at the front and rear of the outer body (2), either door may be used as the entrance/exit for the laundry (36), and both opening/closing doors (15) and (17) are There is no need to use it. In short, it can be determined as appropriate in relation to the production line of the dust control product. In addition, the washer-extractor (
It is effective to install a device that allows the washer-extractor (33) and the oil-impregnated dryer (35) to tilt in order to be effective when taking out the laundry (36) from the washing machine (33) (not shown). . As described above, in the present invention, the oil agent is sprayed in the drum (1) in the oil agent impregnation dryer (35) in a state before drying in which the object to be washed (36) itself contains sufficient moisture. , the impregnation of the oil agent is attempted to be uniform, but in the original drying process performed afterwards using the same oil agent impregnation dryer (35), the viscosity of the oil agent is reduced by the rotation of the drum (1) and the hot air heated by steam. In addition, the distribution of the oil is achieved by the rubbing effect between the items to be washed in the dryer.

It is possible to achieve more complete uniformity. In addition, moisture adhering to the items to be washed (36) during drying is removed from the oil impregnated dryer (36).
5) When it is scattered in the dust, only the oil component remains due to the difference in vaporization temperature and has a dust control function.

FIG. 4 is an explanatory diagram schematically showing the manufacturing process in the method for manufacturing dust control products using the oil impregnation dryer (35) according to the present invention. That is, a washer-extractor (33
), the items to be washed (36) are taken out, conveyed on a belt conveyor (34), placed in an oil impregnating dryer (35), and after the oil impregnation is completed, the original drying process is carried out. The entire manufacturing process of the dust control product is completed.

A brief explanation will be given of an actual usage example regarding the oil impregnation process according to the present invention. First, turn on the power,
The oil temperature is maintained constant by heating with a preheater (26). Then, the opening/closing door (15) is opened and the items to be washed (36) are placed into the drum (1). By pressing the start button, the drum (1) will automatically rotate according to the set rotation speed.
is rotated, and the object to be washed (36) also starts rotating accordingly. Then, with the rotation of the drum (1) controlled in advance, the process of spraying the oil agent with the spray nozzle (29) is adjusted by balancing as described later, and the balancing rotation and loosening rotation are performed alternately. is repeated several times. Kowara is a sea dancer
or computer controlled. As a result, the drum (1
) is controlled, and the remaining moisture in the fibers of each item to be washed (36) is then dried by high-temperature rotation, while the sprayed oil is evenly impregnated throughout the fibers. And make it completely possible. As described above, in the present invention, the impregnation with oil is not performed during the washing or rinsing process of the item to be washed (36), or during the conventional dehydration process, but rather as a pre-process before drying in the dryer. 36) is impregnated with an oil agent. It is also an oil impregnation dryer (35)
Due to the synergistic effect of balancing rotation and loosening rotation due to the centrifugal force accompanying the rotational force of the inner drum (1), it is possible to reduce the loss of the sprayed oil, and Even among a large number of items to be washed (36) manufactured in
By pressing against each other (rubbing effect), the distribution of the spray of the oil agent itself is made uniform, and ■.
6) Even if it is something like a mop, the surface and inside, as well as the outside and center, can be uniformly impregnated with the oil even when looking at the mop itself. This■■■
Let me explain in a little more detail. In other words, (2) is that when a conventional oil spraying device is used to spray an oil agent while the drum of the device rotates after drying the object (36), the oil agent flows out from the opening of the punch hole. This caused so-called oil loss.

In order to improve this point, in the present invention, when balancing the oil impregnated dryer (35) (for example, attaching a motsu to be washed inside the drum and filling the opening of the punch hole with a motsu layer = centrifugal force) By spraying the oil agent in a state in which the object (36) and the object to be washed (36) are balanced, it has the effect of equalizing the oil agent and the object to be washed (36) and preventing leakage (loss) of the oil agent from the opening of the punch hole. Next, regarding item (1), since during the balancing spray, the oil agent is sprayed only on the surface of the object to be washed (36), for example, the mop layer, a step of loosening the object to be washed (36) is added.

By repeating the balancing spray and loosening process about 4 to 9 times, the oil is evenly distributed between the mops. Finally, regarding (■), as a result of high-temperature rotation in the dryer, the motsup itself and between the motsup are made uniform, and the dispersion of the oil agent at the tip and root of the pile is eliminated, and the stickiness on the motsup pile surface ( Oil-rich M
) will be improved.

Next, the remarkable effects of the present invention will be explained with reference to experimental examples.

Experimental Example 1 The experimental example shown in Figure 5 uses a small household motsupu, and the balance spray and loosening process are about 5 minutes, followed by the drying process for about 60 minutes, for a total of about 65 minutes. The process has been completed.

As a result, as can be easily understood from FIG. 5, it was confirmed that the oil agent was well distributed.

<Experimental Example 2> The experimental example shown in Figure 6 uses a small motsu.In the conventional method, more oil adheres to the tip of the motsu than to the base, resulting in stickiness. It is also superior to conventional methods in the important aspect of uniformly dispersing the oil to the items being washed.

It can be easily understood from the results of the comparative experiment shown in FIG. 6 that the present invention is very superior.

<Effects of the Invention> The oil impregnation dryer used in the manufacturing process of the dust control product according to the present invention is configured with an oil impregnation method using the synergistic effect of the balancing rotation and loosening rotation due to dehydration as described above. When manufacturing motupu and cloth.

Conventional oil spraying equipment only sprays oil in the form of a mist onto the surface and tips of mops and cloths, resulting in stickiness caused by the oil from finishing workers, resulting in an extremely poor working environment. According to the present invention, there is no stickiness caused by oil, and the working environment can be significantly improved. However, in the present invention, since the oil agent is sprayed onto the mop etc. in a water-containing state, there is no scattering of the oil agent and there is no deterioration of the manufacturing environment at all.

Additionally, since the spray is not a mist but a liquid, the working environment can be greatly improved.

Next, according to the present invention, there is no restriction on the types of items to be washed. Specifically, in the conventional method, when the material is cotton, internal penetration into the fiber can be expected for a long time, but when using chemical fibers, the sticky feeling is very strong and it is difficult to use. However, according to the present invention,
Even chemical fibers such as mops are extremely easy to process and uniform, and can be impregnated with oil evenly, greatly expanding the range of applications. ③Also, in the conventional technology, spraying is performed after the drying process is completed, so it is impossible to uniformly spray objects such as large motsus or cloth, but the present invention overcomes such limitations. It is possible to spray evenly. and,
(2) In the present invention, since the fibers can be impregnated with the oil in the oil impregnation dryer, there is no need for an independent impregnation processing device, and there is no need for special costs or installation space. Furthermore, by using the present invention, the line balance in the manufacturing process is leveled and automated.

Effects such as easy labor saving can be expected, and the above-mentioned object of the present invention is fully achieved.
