Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a multi-liquid mixing and discharging device that uses a static mixer that mixes fluids without using a power source.

[Conventional technology]

Conventionally, as a device for mixing and discharging multiple liquids (hereinafter sometimes referred to as a "multi-liquid mixing and discharging device"), a mixer and an on-off valve that adjusts the discharge amount of the mixed liquid are installed separately. be.

As shown in the schematic diagram of FIG. 6, such a multiple liquid mixing and discharging device includes a mixer 32 provided with stirring blades 31 rotated by a motor M, and a mixed liquid mixed in the mixer 32. There is a so-called batch type multi-liquid mixing and discharging device 34 that is equipped with an on-off valve 33 that adjusts the discharge amount.

The multi-liquid mixing and discharging device 34 stirs and mixes liquids A and B, which have been charged into a mixer 32 in advance, using a stirring blade 31 disposed in the mixer 32, and then stirs and mixes the mixed liquids for a long time. The fluid is forced to flow through the communication pipe 35 to the discharge section 36 by the pump P, and is discharged.

Note that an on-off valve 33 for adjusting the discharge amount is disposed at an intermediate position between the pump P and the discharge portion 36, and the discharge amount of the mixed liquid discharged from the discharge portion 36 is adjusted by the on-off valve.

By the way, in today's high technology industry, curable resins with a short curing time are becoming mainstream due to demands for improved product performance and productivity among two-component curable resins used, for example, as adhesives. ing.

Therefore, a multi-liquid mixing and discharging device for mixing and discharging such two-component curable resins is required to be capable of using a curable resin that takes a short curing time.

However, in the batch type multiple liquid mixing and discharging device 34, a large amount of the mixed liquid mixed in advance in the mixer 32 as described above may start to harden in the mixer 32, or the discharge amount may be reduced by the on-off valve 33. The communication pipe 3 is long until it is adjusted and discharged from the discharge part 36.
During the time 5, curing starts, which may cause clogging in the pipe and impede the discharge of the mixed liquid.

To solve this problem, a two-liquid mixing and discharging device 38 has been proposed that is equipped with a static mixer 37 that does not use a power source, as shown in the schematic diagram of FIG. 7.

The two-liquid mixing and discharging device 38 pressure-flows liquids A and B into the static mixer 37 through two long communication pipes 39a and 39b using individual pumps P1 and P2. It is used to mix two liquids.

In this case, pumps P1, P2 and static mixer 3
Opening/closing valves 40a, 40b for adjusting the discharge amount are disposed at intermediate positions of the communication pipes 39a, 39b between the pipes 7 and 7, respectively.

By using the static mixer 37 shown in FIG. 7, the volume of liquid after mixing in the device can be reduced compared to the batch type device shown in FIG. 6, and the curable resin that hardens in a short time can be It is possible to use

[Problem that the invention attempts to solve]

However, in the two-liquid mixing and discharging device 38 using the static mixer, a predetermined length of communication pipe 39a',
39b', and the existence of these pipes causes a time lag between the valve adjustment of the on-off valves 40a and 40b and the discharge from the static mixer 37.

In addition, such communication pipes 39a, 39a', 39b,
The material of 39b' is usually made of flexible synthetic resin that is easily deformed, but due to expansion or contraction of the communication pipe due to various causes, the liquid A,
If the supply amount of B or the discharge amount from the mixer becomes inconsistent and accuracy of the discharge amount is required,
Use of such devices can be difficult.

The present invention was developed against the background of such problems in the conventional technology, and it is possible to reduce the internal volume of the device after mixing multiple liquids, and to adjust the on-off valve that adjusts the discharge amount and the discharge of the mixed liquid. It is an object of the present invention to provide a multi-liquid mixing and discharging device that can provide quick response and improve the accuracy of discharge amount.

[Means for solving problems]

That is, the present invention is a multi-liquid mixing and discharging device characterized by having a static mixer for mixing a plurality of liquids, and an on-off valve disposed at an appropriate position near the mixer to adjust the discharge amount of the mixed liquid. be.

[Effect]

The present invention allows multiple liquids to flow into a static mixer, and the multiple liquids are mixed while flowing through the mixer. This mixed liquid is discharged while adjusting the discharge amount with an on-off valve that adjusts the discharge amount arranged at an appropriate position near the static mixer, thereby making it possible to reduce the internal volume of the device after mixing multiple liquids, Moreover, it is possible to provide prompt response to the valve adjustment of the on-off valve and the discharge of the mixed liquid, and furthermore, the accuracy of the discharge amount is improved.

〔Example〕 Hereinafter, the present invention will be explained in detail based on the drawings.

Fig. 1 is a schematic diagram of a two-liquid mixing and discharging device according to an embodiment of the present invention, and Fig. 2 is a mixing tool used in the two-liquid mixing and discharging device shown in Fig. 1, with a right-handed helical groove carved. A front view of a mixing device in which a helical shaft with a left-handed spiral groove is fitted into a passage pipe, FIG. 3 is similar to FIG.
A line cross-sectional perspective view, FIG. 4 shows a stationary type mixing tool shown in FIGS. 2 and 3, and a mixing tool in which a passage pipe and a mixing tool in which the spiral grooves of the helical shaft have different turning directions are stacked alternately. FIG. 3 is a partial vertical cross-sectional view of the mixer.

First, referring to FIG. 1, a two-component mixing and discharging device 1 for mixing a two-component curing resin includes a stationary mixer 2 , a pump P1 that pressure-flows the base material A into the mixer 2 , and a communication line that communicates these. A pipe 3 and a pump P2 that pressure-flows the curing agent B into the static mixer 2 , a communication pipe 4 that communicates these, and a discharge housed in the vicinity of the static mixer 2 , that is, in this case, near the tip of the mixer 2 . It consists of an on-off valve 5 that adjusts the amount, and a discharge needle 6 installed at the tip of the mixer 2 .

The on-off valve 5 is not limited to the one housed near the tip of the static mixer 2 , but may be located at any position as long as it adjusts the discharge amount of the mixed liquid. Alternatively, it can be installed at any position near the static mixer 2 , such as in the middle of the mixer 2 .

Thus, according to the present invention shown in FIG. 1, the main agent A and the curing agent B are mixed by being forced into the static mixer 2 in fixed amounts at a time via the communicating pipes 3 and 4 by synchronized pumps P1 and P2. . The discharge amount of the mixed liquid is adjusted by an on-off valve 5 housed near the tip of the mixer 2 , and is discharged from a discharge needle 6 installed at the tip of the mixer.

In this way, the present invention reduces the volume of liquid from the time when base agent A and hardening agent B come into contact to the needle tip, and also minimizes the distance from each pump to the mixer. It is possible to keep the supply amount constant, and therefore the accuracy of the discharge amount is greatly improved.

Note that the multiple liquid mixing and discharging device of the present invention has the following features:
It is not limited to the mixing of the two-component mixed type curing resin shown in Figure 1, but can also be used to mix many other types of mixed type curing resins or non-curing fluids such as paints and chemicals. .

Further, as the mixer 2 used in the multiple liquid discharging device of the present invention, a conventionally known static mixer,
For example, Japanese Patent Publication No. 44-8290 or Japanese Patent Application Publication No. 58-
It is possible to use the mixer described in Japanese Patent No. 128134, but more preferably, for example, the mixer described in the present invention Nos. 2 to 4
It is preferable to use the mixer shown in the figure (for details, refer to the patent application filed at the same time as the present invention, title of the invention: "Fluid mixer").

That is, FIG. 2 shows a mixing tool used in the mixer 2 in the two-liquid mixing and discharging device 1 shown in FIG. Front view of a mixing tool with a spiral shaft inserted, 3rd
The figure is a cross-sectional perspective view taken from Fig. 2, and Fig. 4 is a cross-sectional perspective view taken from Fig. 2.
FIG. 3 is a partial longitudinal cross-sectional view of a static mixer in which a mixing tool shown in FIG. 3 and mixing tools whose spiral grooves have different turning directions are stacked alternately.

Now, as the mixer 2 used in this invention,
A mixing tool 9 having a passage pipe 7 with clockwise spiral grooves 7a, 7b carved on the entire length of the inner circumferential wall and a spiral shaft 8 with spiral grooves 8a, 8b carved on the outer circumferential wall (see Figs. 2 and 3). The mixing tool 9 can be one in which a passage pipe and a mixing tool 10 in which the spiral grooves formed on the helical shaft have different turning directions are alternately stacked so that the contact surfaces overlap (the fourth (see figure).

First, let's talk about the mixing tool 9 used here.
To explain in detail with reference to Figures 3 to 3, the mixing tool 9
In this example, two right-handed spiral grooves 7a and 7b having a semicircular shape when viewed in cross section perpendicular to the spiral direction are formed with one lead (360 degrees) spiral grooves extending through both end surfaces over the entire length of the inner circumferential wall of the passage pipe 7. A spiral shaft 8 having two spiral grooves 8a and 8b of the same shape and spirally carved in the outer circumferential wall is fitted into the passage pipe 7.

At this time, a spiral groove 7 is formed on the inner peripheral wall of the passage pipe 7.
Threaded portions 7c and 7d are formed by the threads a and 7b, and threaded portions 8c and 8d are formed on the outer circumferential wall of the helical shaft 8 by the threaded grooves 8a and 8b, respectively.

The inner diameter of the thread 7c or 7d of the passage pipe 7 and the outer diameter of the thread 8c or 8d of the helical shaft 8 are shaped so that they almost match, and the passage pipe 7
It is preferable that the helical shaft 8 is freely fitable therein, that is, in a "clearance fit", "stop fit", or "interference fit" state.

When using this mixing tool 9, for example, the main ingredient A and the curing agent B, which are the substances to be mixed, are placed in the spiral grooves 7, respectively.
The water is poured into inlets A1 and B1 formed by a combination of a-8a and 7b-8b.

Here, the main agent A poured into the inlet A1 flows along the right-handed spiral groove 7a formed in the passage pipe 7 and the left-handed spiral groove 8a formed in the helical shaft 8 into the mixing tool 9. The flow circulates inside each in opposite directions.

In addition, the curing agent B poured into the inlet B1 has a right-handed helical groove 7b formed in the passage pipe 7 and a left-handed helical groove 8b formed in the helical shaft 8, as in the case of the main agent A. The water flows through the mixing tool 9 in opposite directions along the respective directions. That is, these fluids A and B
are already 2 each near the inlets A1 and B1.
It is divided into partial streams.

As this flow progresses, the dividing surface of the partial flow of the main agent A flowing through the spiral groove 7a of the passage pipe 7 and the hardening agent B
The dividing surface of the partial flow flowing through the helical groove 8b of the helical shaft 8 makes surface contact in a cylindrical shape.

Similarly, the dividing surface of the partial flow of base agent A flowing through the helical shaft 8a and the dividing surface of the partial flow of curing agent B flowing through the spiral groove 7b come into cylindrical surface contact.

At these contact surfaces, turbulence occurs due to the different flow directions, resulting in a mixing effect, so-called turbulent mixing.

As the flow progresses further, each partial flow passes through the passage pipe 7.
The partial flow reaches the joint between the threaded portion 7c of the helical shaft 8 and the threaded portion 8c of the helical shaft 8, where each partial flow temporarily interrupts the contact turbulent mixing, corrects the flow, and promotes the contact turbulent mixing that starts next. let

These threaded portions 7c, 7d and threaded portions 8c, 8d
The part where they are joined is the spiral groove 7 on the passage pipe 7 side.
a, 7b are two threads, helical grooves 8a, 8b on the helical shaft 8 side
In this embodiment, there are two strips in total, and the contact turbulent mixing is repeated as many times as there are eight strips.

On the other hand, fluid generally has the property of flowing through a place with low resistance, and this tendency is also seen in the flow of the main agent A and the curing agent B in the mixing tool 9 of this embodiment, and the fluid flows at a certain place. Spiral intersecting spiral grooves 7a, 7
8a and 8b. This operation of the main agent A and the curing agent B has the effect of promoting the catalytic turbulent mixing.

Moreover, the spiral grooves 7a, 7b or 8 of the mixing tool 9
When main agent A and curing agent B flow through a and 8b, a phase shift occurs on a cylindrical surface perpendicular to the flow due to the inertia of the fluid, and there is no contact with the cylindrical contact surface of liquids A and B. The liquids A and B are sequentially exchanged between the threaded parts 7c, 8d or 8c,
Partial flows of fluids A and B are divided at the junction 7d.

In addition, in the present invention, the material of the passage pipe 7 and the spiral shaft 8 is polycarbonate, polyethylene,
polypropylene, polyethylene terephthalate,
In addition to plastics such as polybutylene terephthalate, epoxy resin, acrylic resin, ABS resin, and fluororesin, aluminum, stainless steel,
It is possible to use metal materials such as iron, nickel, copper, and titanium, inorganic materials such as ceramics and carbon fiber, and even composite materials that combine multiple of these materials (for example, carbon fiber reinforced plastics). . In this case, a heat-resistant, abrasion-resistant, and corrosion-resistant coating may be applied to the surface of the mixing tool made of plastic, metal, or inorganic material.

Further, the shape of the passage pipe is not limited to a cylindrical shape, and any shape is possible as long as a spiral groove can be carved into the inner circumferential wall.

Therefore, the mixing tool used in the present invention is as follows:
For example, a plurality of helical shafts may be fitted into a long passage pipe, or a plurality of long passage pipes may be bored from one side of the block body to the other face, and a spiral shaft may be inserted into each of these passage pipes. It may also be formed by inserting a shaft.

Furthermore, the number of spiral grooves formed on the passage pipe 7 and the spiral shaft 8 may be 1, 2, 3, 4, etc. depending on the number of liquids to be mixed and their properties.
The number can be selected as appropriate.

Furthermore, the spiral groove 7a in one mixing tool,
The number of leads of 7b or 8a, 8b is not limited to one lead, and any number of leads is possible.

Furthermore, within the passage pipe 7, the helical shaft 8 fitted into the pipe is usually fixed, for example, respectively, or with screw threads 7c,
The contact portions between 7d and 8c, 8d are fixed by welding or adhesive, but the helical shaft 8 may be rotatable within the passage pipe 7 without being fixed.

In this embodiment, spiral grooves 7a with different turning directions,
7b and the spiral grooves 8a and 8b, the number of intersection points where each groove contacts increases, and therefore more efficient mixing of fluids is possible.

The mixer shown in FIG. 4 has such a mixing tool 9 and a mixing tool 10 having a spiral direction opposite to that of the spiral groove of the mixing tool alternately stacked one on top of the other.

That is, the mixing tool 10 used in FIG.
Two spiral grooves 1 that turn left on the inner peripheral wall of the passage pipe 11
1a and 11b are threaded with 1 lead, and the spiral shaft 1
Two right-turning spiral grooves 12a and 12 are provided on the outer peripheral wall of 2.
b and one lead screw.

In addition, the mixing tool 9 or 1 used in the present invention
0 is not limited to a mixing tool in which the spiral shaft and the spiral groove of the passage pipe have opposite directions of rotation, as shown in FIGS. The mixing tool may be such that the direction of rotation of the spiral groove of the passage pipe and the direction of rotation of the spiral groove of the helical shaft are right-handed or left-handed, respectively.

However, in order to efficiently perform the divided mixing, turbulent mixing, and phase-shifting mixing, it is necessary to make sure that the spiral grooves of the passage pipe and the spiral grooves of the helical shaft are in the same direction as each other, as illustrated in FIGS. 2 to 4. Different mixing tools are good.

The thus formed mixing tools 9 or 10 are usually stacked and used as a mixer as shown in FIG. 4, but in this case, various mixing tools with different rotation directions are combined. It is effective to use.

For example, FIG. 4 shows one in which mixing tools 9 and 10 are alternately stacked.

At this time, it is best to connect the stacked mixing tools 9 and 10 so that the surface shapes of both end portions of both mixing tools 9 and 10 overlap.
It is also possible to perform polymerization by shifting the surface shapes of the mixing tools 9 and 10 at any angle within a range of 150 degrees.

However, when connecting by shifting the surface shape at an arbitrary angle, the periphery of the inlet should be rounded to reduce the resistance of fluids A and B generated at the periphery of the inlet of the next mixing device, or It is preferable to insert a spacer (not shown) between these mixing tools in order to smoothly guide the mixing tools.

In addition, the mixer 2 shown in FIG.
Although it is constructed by alternately stacking a plurality of mixing tools 9 and 10, it is not limited to this, and for example, it is also possible to use the mixing tool 9 or the mixing tool 10 alone.

When using the mixer 2 configured in this way, first, the inlets A1 and B1 of the first mixer 10 are
When fluids A and B are respectively poured into the channel, each of the fluids A and B flows into the left-handed spiral groove 1 on the passage pipe 11 as described above.
1a, 11a and the right-handed spiral grooves 12b, 12b on the spiral shaft 12, the fluid flows through the mixing device 10, and during this time, the phase of the fluid is shifted, and the screw thread on the passage pipe 11 side 11c, 11d and spiral shaft 12
Contact turbulent mixing and split mixing are repeatedly performed between the eight joints with the side threads 12c and 12d.

In this way, the liquids A and B mixed in the first mixing tool 10 are passed through the next second mixing tool 9, and in this mixing tool 9, as described above, the passage pipe 7
The fluid flows through the mixing device 9 according to the upper right-handed spiral grooves 7a, 7b and the left-handed spiral grooves 8a, 8b on the helical shaft 8, and during this time, the phase of the fluid is shifted, and the passage Contact turbulent mixing and split mixing are repeatedly performed between the eight joints between the threads 7c and 7d on the tube 7 side and the threads 8c and 8d on the helical shaft 8 side.

Similarly, fluid A was mixed more finely with mixer 9.
The mixing process is repeated sequentially, and B is further transferred to the third mixing tool 10 and the fourth mixing tool 9, and finally, the mixed fluid AB, which is completely and uniformly mixed, is delivered to the outlet A2 of the mixer 2 . , B2.

Note that the mixing tool used in the mixer 2 is not limited to the mixing tool 9 or 10 described above, in which the spiral grooves formed on the passage pipe and the helical shaft have different turning directions. The mixing tool may have grooves that rotate in the same direction.

However, in general, it is better to use a mixing tool in which both the spiral grooves rotate in different directions from the viewpoint of mixing efficiency.

In addition, the stacking method of the mixing tools is such that mixing tools 9 and 10 having different rotation directions, as in the mixer 2 shown in FIG.
It is not limited to stacking the mixing tools alternately, but it is also possible to stack only the mixing tools of the same rotation (for example, stacking only the mixing tool 9), or after stacking multiple mixing tools in one direction, stacking the mixing tools in the other direction is possible. It is also possible to laminate a plurality of mixing tools.

However, a mixer in which single mixers having different rotation directions (for example, mixers 9 and 10) are stacked alternately has better mixing efficiency.

Next, a more specific embodiment of the multiple liquid mixing and discharging device of the present invention will be described with reference to FIG.

FIG. 5 shows a more specific embodiment of the present invention, and is a configuration diagram of a handy type two-liquid mixing and discharging device.

In FIG. 5, the two-liquid mixing and discharging device 14 mainly includes a valve body 15 serving as a main body, a static mixer 16 that mixes the base agent A and the curing agent B, an on-off valve 17 that adjusts the amount of mixed liquid to be discharged, and the on-off valve. It consists of an air cylinder 18 that opens and closes the air cylinder 18, and a pump (not shown) that pressure-flows the main agent A and curing agent B into the static mixer 16.

Here, a large-diameter nut hole 19 is formed in the center of the lower part of the valve body 15, and the nut hole 19 accommodates a static mixer 16 of the same type as the static mixer 2 shown in FIGS. A container storage cylinder 20 is screwed onto the container.

At the lower part of the mixer housing cylinder 20, an inflow part 20a for the main agent A and curing agent B is installed, and in the upper end of the housing cylinder there is a hole for flowing the liquid mixture mixed in the mixer into the valve body 15. Outflow holes 20b are formed.

It is housed in a slidable manner so that the passage of the mixed liquid can be closed by moving the valve.

Further, a bearing 23 is fitted into the other end of the rod insertion path 21a to prevent leakage of the liquid mixture and to improve sliding of the rod 21.

A discharge hole 24 for the mixed liquid is formed at the tip of the slide chamber 22, and a discharge needle 25 is inserted into the discharge hole 24.
is installed.

Further, the air cylinder 18 for opening and closing the on-off valve 17 is screwed into a mounting hole 26 formed at the other end of the valve body 15, and a rod 21 is connected to the air cylinder 18.

Further, the opening/closing switch is not limited to one attached to the hand grip 30, and may be other switches such as a foot switch, a proximity switch, or a photoelectric switch.

Although the air cylinder 18 is employed here as the actuator for opening and closing the on-off valve 17, a hydraulic cylinder, an electromagnet, a spring, or the like may also be used, for example.

When using the two-liquid mixing and discharging device shown in FIG. 5, first, the base agent A and the curing agent B are forced into the inflow portion 20a using a pump (not shown).

The main agent A and curing agent B that have been forced to flow become a uniform liquid mixture while rising through the static mixer 16, and are forced to flow into the rod insertion path 21a through the outflow hole 20b and the inflow hole 15a.

Here, when the tip of the discharge needle 25 is directed toward the target and the operating switch 29 is turned on, the switching valve 2
7 is switched, and the air from the air source is force-fed to the air cylinder 18 via the air pipe 28.

As a result, the air cylinder 18 is

Therefore, the liquid mixture in the rod insertion path 21a flows into the slide chamber 22 and is discharged from the discharge needle 25.

There are two types of this discharge: line drawing discharge and point discharge. In the case of the line drawing discharge, while the actuation switch 29 is turned on, the switching valve 27
An electric circuit (not shown) is set so that the valve remains open, and in the case of point discharge, a timer (also not shown) is installed in the circuit to control the return time (valve closing time) of the switching valve 27. This is what you do.

In this way, in this embodiment, the multi-liquid mixing and discharging device is made into a handy type, and the previously large mixing and discharging device is now lightweight and compact, making it easy to transport and significantly reducing the cost of the device.
