Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Application for J-Graduate School) The present invention relates to an emulsifying device that emulsifies a plurality of liquids having different liquid phases by colliding with each other.

(Prior Art) Various types of emulsifying devices have been proposed for mixing, for example, fatty liquids and aqueous liquids.

Among these, the invention described in Japanese Patent Application Laid-open No. 151676/1984 is a technique that utilizes the collision force caused by high-pressure jetting of liquid. In this invention, a target liquid is injected at high pressure from a nozzle into a relatively wide gap, and the injected liquid is made to collide with the end surface of a magazine in which a conduction hole is formed at a position different from the axis of the injection port of the nozzle. The emulsified material is emulsified when it is recovered through the through hole or collided with the end face of the magazine again.

However, this invention involves adding an emulsifier to the plurality of liquids and mixing them in advance to emulsify the mixture, which is not suitable for emulsifying a plurality of liquids that cause a chemical reaction during mixing.

There is also an invention disclosed in US Pat. No. 1,496,858 as an apparatus for emulsifying a plurality of liquids by colliding them with each other. This invention changes the flow in the radial direction at an appropriate position while the liquid injected from the individual nozzles passes through a liquid passage formed through U1 in the axial direction of the device body, and here the two liquids collide to emulsify. This is what we aim to do.

However, in this invention, the liquid passage passes through the block-shaped interior of the device main body in the axial direction, and each passage must be formed with high precision, making manufacturing difficult and likely to result in high costs.

In addition, in both inventions, it is difficult to make the diameter of the flow path such as the liquid conduction hole or passage extremely small, so one liquid collision part is not enough, and it is necessary to provide this in multiple stages in the axial direction of the device body. There is. However, if such a configuration is adopted, not only will it become even more difficult to form a flow path,
The device itself becomes long, and in reality, the liquid pressure drops rapidly after the first collision, making it impossible to emulsify sufficiently.

(Object of the Invention) In view of the problems of the prior art described above, the present invention is capable of independently jetting and mixing liquids to be emulsified without pre-mixing them, is easy to manufacture, and is capable of controlling the direction and diameter of liquid passages. The object of the present invention is to provide an emulsifying device that can be easily selected and changed according to the liquid to be emulsified.

(Structure of the Invention) In order to achieve the above-mentioned object, the present invention provides a plurality of nozzles through which liquids of different liquid phases are jetted at high pressure, and a plurality of nozzles are arranged at required intervals, and a position communicating with the tips of these nozzles is provided. A mixing chamber for emulsifying and mixing the liquid injected from the nozzle is provided in the mixing chamber, and a discharge passage communicating with the mixing chamber is provided at the rear of the mixing chamber. The liner members are superimposed and fixed, and the plate surfaces of the first liner member and the second liner member are provided with guiding holes that guide the liquid jetted from the nozzle so that the flow direction is changed and the liquid is gradually brought to one point. is formed, and a mixing hole is formed in the plate surface of the third liner member to collide and mix the plurality of liquids that have approached through the guide hole, and the fourth liner member is further formed with a mixed liquid. It is characterized in that a discharge hole is formed to guide the liquid to the discharge path.

The four liner members 15 to 18 each have a disc shape that is approximately the same diameter as the inner peripheral surface of the mixing chamber forming block 8, and have through holes 19 to 25 of different shapes on their plate surfaces, respectively. While both liquids are introduced to the discharge path 13 through the through holes 19 to 25, the two liquids are caused to collide and emulsify and mix.

To explain these with reference to FIGS. 2 to 5, first, the first
As shown in FIG. 2, the liner member 15 has a vertically long slit-shaped guide hole 19, 20 in the center of the plate surface, with two vertically extending
The long holes 19 and 20 are formed in series, and the outer ends of the long holes 19 and 20 communicate with the through holes 9 and 10 of the mixing chamber forming block 8. The guide holes 19 and 20 are both formed to have a width slightly larger than the diameter of the through hole 9 and 10.

The second liner member 16 is superimposed on the back surface of the first liner member 15, and the second liner member 16 is positioned on the plate surface communicating with the inner end of the guide elongated hole 19, 20 of the first liner member 15, as shown in FIG. Guide hole 2 with the same diameter as the width of the guide slot 19 and 20 above.
1.22 is formed, and a horizontally elongated retention hole 23 is formed in the center of the guide hole 21.22.
It is formed separately from 2 without communicating with it.

The third liner member 17 superimposed on the back surface of the second liner member 16 has a cross-shaped mixing hole 24 in the center of the plate surface.
is formed. The outer end of the vertical hole portion of this through hole 24 coincides with the through holes 21 and 22 of the second liner member 15 described above, and the horizontal hole portion corresponds to the retention through hole 2 of the second liner member 16.
It is formed to match 3.

Furthermore, the fourth liner member 18 superimposed on the back surface of the third liner member 17 has a horizontally elongated discharge hole 25 formed in the center of its plate surface. This discharge hole 25 is formed to have the same shape and size as the horizontal hole portion of the mixing hole 24 of the third liner member 18 and the retention elongated hole 23 of the second liner member 16. It communicates with the presser block l on the back side! Exhaust route! It communicates with 3.

In the fourth to fourth liner members 15 to 18 constructed in this way, in a polymerized state, the through holes 19 to 25 communicate with each other as shown in FIG. 6, and a liquid passage whose outflow direction changes is formed as a whole. These runner parts 15 to 8
As shown in FIG.
0 mm, second liner member 16 1 mm, third liner member 17 0.11 mm, fourth liner member 18
is 3 mm, the third liner member 17 is the thinnest, and the fourth liner member 18 is the thickest. Of course,
This thickness is not particularly limited in the present invention, and may be set to an appropriate thickness.

In addition, the reference numeral 26 in the figure indicates each of the liner members 15 to 18.
This is a positioning notch provided at an appropriate location on the circumferential surface.

The operation of this device will be described with reference to FIGS. 7 and 8. First, the liquids separately pumped from the nozzle members 2 and 3 in FIG. The liquid is injected into the first liner member 15 through the through hole 5.6 provided in the first liner member 15.

The through hole 5.6 is the guiding elongated hole 19 of this liner member 15.
．． The guide elongated hole 19°20 itself communicates with the outer end of the mixing chamber forming block 8 and the second liner member 1.
6 to form a liquid passage, the injected liquid passes through this passage and reaches the liner member 15.
move toward the center of

The liquid that has reached the inner end of the guide elongated hole 19.20 passes through the guide hole 21.22 of the second liner member 16 and reaches the outer end of the vertical hole portion of the mixing hole 24 of the third liner member 17. From here, they flow toward the center, where they collide with each other and are emulsified and mixed. Since the third liner member 17 is formed thinner than the other liner members 18 as described above,
The flow velocity increases while passing through the mixing hole 24, and both liquids collide rapidly. The mixed liquid is taken out of the device from the discharge hole 25 through the discharge path 13. At this time, since the elongated retention hole 23 is formed in the second liner member 16, the mixed liquid is easily discharged through the discharge path 13.

In addition, in the present invention, when guiding, colliding, and discharging liquid,
As seen in the embodiments described above, it is necessary to provide at least four liner members, but depending on the case, a larger number of liner members may be provided.

In addition, the through hole forms a flow path when the liner members overlap each other and is regulated by the plate surface, but the flow rate of the liquid flowing through the stiffness can be adjusted by appropriately changing the size, shape, etc. of the through hole. This can be easily achieved, and therefore, the shape etc. may be appropriately set depending on the type of liquid, etc.

Of course, the present invention can be implemented in the same manner when two or more liquids are mixed by increasing the number of nozzle members and through holes.

(Effects) As described above, according to the present invention, liquids to be mixed are individually injected at high pressure from the nozzle members, four liner members are fixed in the mixing chamber communicating with the open end of the nozzle members, The various through holes formed on the plate surface of this liner member allow liquids to gradually approach each other and emulsify and mix by colliding with each other, making it possible to emulsify and mix the target liquids independently without mixing them in advance. Moreover, a liquid flow path can be easily and accurately formed simply by forming through holes in a plate-shaped liner member.

Furthermore, according to the present invention, the fluid flow path is determined by the shape, diameter, length, etc. of the through hole in the liner member, so the flow path in this type of device can be freely formed.

Further, according to the present invention, even if the liquid flow path becomes clogged, the liner member can be taken out from the mixing chamber and easily removed.
