[0002]

2. Description of the Related Art Emulsification and dispersion of substances are carried out by a stirrer, and crushing is carried out by a bead mill or the like.

[0003]

However, the above-mentioned conventional stirring type apparatus has poor stability of emulsification and dispersion after the treatment, and the crushing apparatus such as the bead mill takes a long time to produce particles of a required size. There was a problem.

[0004] Accordingly, an object of the present invention is to improve the stability of emulsification and dispersion, and to solve the above-mentioned problems that fine particles can be produced in a short time in crushing.

[0005]

According to the present invention, in order to achieve the above object, according to the first aspect of the present invention, a liquid containing a substance is applied to an accelerator provided with two disks by applying pressure to each of the disks. In each case, one through passage penetrating the surface and one groove-like passage formed on the surface connected thereto are provided halfway on the surface, and the discs are opposed to each other with the surface having the groove-like passage, and the through passages are connected to each other. The groove-shaped passages are joined so as to intersect or connect so that they do not overlap, and the cross-sectional area of the flow passage of the groove-shaped passage is smaller than the area of the through hole formed by the groove-shaped passages formed in the joint surface. And the flow is bent at an angle in front of the through-opening so as to cause acceleration in a section before and after the bent portion, and moreover, the distance from the bent portion to the through-opening is shortened. Thereafter, while promoting the effect of the acceleration in addition to the passage being expanded, the material is atomized by passing through a series of flow paths of the respective disks by the interaction of impact force and various physical phenomena due to the acceleration, It is characterized in that it is taken out from the accelerator and a pipe after passing through the accelerator, and in a modified example, a pressure is applied to a liquid containing a substance to introduce the liquid into an accelerator equipped with two disks, One through-passage penetrating the surface is provided for each disc, and two discs are joined so that the through-passages do not overlap with each other, and the flow on one of the disc surfaces so that the through-passages of the respective discs communicate with each other. Providing a groove-shaped passage formed on the surface with a flow passage cross-sectional area smaller than the flow passage cross-sectional area of the through passage at the width of the through passage of the first disk upstream of the first disk, By bending the flow at an angle just before entering the grooved passage, acceleration is caused in the section before and after the bent portion, and furthermore, the distance of the grooved passage is made as short as possible from the bent portion, and thereafter the passage is expanded. While promoting the effect of the acceleration in addition to being performed, the interaction between the impact force and various physical phenomena due to the acceleration causes the substance to pass through a series of flow paths of each of the disks and is atomized, and the accelerator and It is characterized in that it is taken out from the pipe after passing through the accelerator, and in claim 2, pressure is applied to the liquid containing the substance and the liquid is introduced into the accelerator equipped with two disks,
The first disk is provided with two through passages penetrating the surface, the two through passages are connected by a groove-like passage on one surface, and the second disk is provided with a through passage penetrating the surface. In one of the two disks, in the middle of the first groove-shaped passage in the two disks, the groove-shaped passage communicates with the through passage in the second disk having a wider width than the groove-shaped passage. Joined, so that twice the cross-sectional area of the flow path of the groove-shaped passage is larger than the area of the through-hole formed in the joint surface, and the two groove-shaped portions are formed in front of the through-hole. The flow of the passage is bent at an angle to cause acceleration in a section before and after the bent portion, and moreover, the distance from the bent portion to the through hole is reduced, and then the passage is expanded. While promoting the effect of acceleration, the acceleration Due to the interaction of impact force and various physical phenomena, the substance is atomized by passing through a series of flow paths of each disk, and is taken out from the accelerator and piping after passing through the accelerator. .

[0006]

When a liquid containing a substance is applied with pressure to the accelerator, the substance passes through a flow path that regulates the flow with the liquid and enters a narrowed flow path. Here, since the flow path is bent at an angle and narrowed narrowly, passing the front and rear of this bent portion causes a rapid increase in speed over a short distance. This change in velocity causes an impact force on the substance and liquid due to acceleration. After passing through the bent portion, the liquid containing the substance at a high speed passes through the narrowest flow path with a short distance, and then the flow path is expanded. This has the function of facilitating the discharge of the liquid containing the substance and enhancing the effect at the bent portion. The impact force and various physical phenomena caused by these rapid changes in speed are generated in the middle of the flow, and the interaction between these causes the material to be atomized, whereby emulsification and dispersion crushing are performed. In this treatment, since the power for producing fine particles is strong, the stability and emulsification and dispersion can be improved in a short time, and the crushing power is extremely high.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. The overall configuration will be described with reference to FIG. For example, in the case of emulsification, 1 is a tank containing water and oil, and it is assumed that water and oil are not completely separated into two layers by a simple stirrer. Passes through the valve 2 and is pressurized by the pump 4 and enters the accelerator 6 through the pipe 5 and is taken out of the pipe 7 under the action. When the desired emulsification is completed, it is recovered at 9 via the 8 valve. If the emulsification is incomplete, it is returned to one tank via 10 pipes, and the processing is performed again.

FIGS. 2 to 7 show an embodiment of the accelerator of the first aspect. The accelerator 6 has two disks 12 arranged in a cylindrical container 11 as shown in FIGS. As shown in FIGS. 2 and 3, the disc 12 is made of a hard and abrasion-resistant material such as diamond and has a diameter of 1 mm.
It is a disc having a size of about 0 mm and a thickness of about 2 mm. There is one through passage (0.8mmφ) 13 and a groove formed on the surface (0.2mm depth and 0.1mm width) connected to it.
14 are engraved. The discs are aligned so that these grooves are combined at right angles as shown in FIGS. Here, through holes (0.1m
m □) 15 are formed, which is the narrowest place in the entire flow path of each disk. The liquid containing the substance under pressure is bent at an angle from a wide channel to a narrow channel in front of the through-hole 15. Speed V ₂ Thus when the speed of V ₁ narrow flow path when a wide flow path, better than V ₁ of the V ₂ the speed increases. Since this speed change is performed within a short distance, the force applied to the liquid containing the substance becomes large. Furthermore, while shortening the distance from the bent portion to the through hole 15 and enlarging the passage after passing, the effect of acceleration is also promoted. After passing through the flow path, the particles are atomized and taken out from the accelerator and the pipe after passing through the accelerator to emulsify, disperse, and crush the substance.

FIG. 8 to FIG. 14 show an embodiment of a modified accelerator. Accelerator 6 is cylindrical container 1

The width continues. The disk 19 has a through passage (1.5 mmφ) 20 as shown in FIGS. Both disks are made of a hard and wear-resistant material such as diamond and are disks having a diameter of about 10 mm and a thickness of about 2 mm. These two disks are combined so that a flow path is formed as shown in FIG. Here, a through passage (0.2 mm × 0.5 mm) is formed by the disks, and the narrowest passage is formed in the entire flow path formed by the disks. The liquid containing the pressurized substance is bent at an angle from a wide channel to a narrow channel before the through passage. When the speed at the wide flow channel to the speed at the V ₃ narrow channel and V _4, who from V ₃ of V ₄ is speed increases. Since this speed change is performed within a short distance, the force applied to the liquid containing the substance becomes large.
Furthermore, the distance including the through passage is made shorter than the bent portion, and the passage is expanded after passing, which further promotes the effect of acceleration, and the interaction of the impact force and various physical phenomena due to acceleration causes the substance to be connected to the series of disks. Are passed through the flow path, and are atomized, and are taken out from the accelerator and the pipe after passing through the accelerator to emulsify, disperse, and crush the substance.

FIGS. 15 to 21 show embodiments of the accelerator according to the second aspect. The accelerator 6 has disks 21 and 22 arranged in a cylindrical container 11 as shown in FIGS. The disk is made of a hard and wear-resistant material such as diamond, and is a disk having a diameter of about 10 mm and a thickness of about 2 mm. Fig. 15 shows the first disk
・ There are two through passages (0.8 mmφ) 23 as shown in FIG. 16, and a groove formed on the surface (0.1 mm depth
24 (0.1 mm width) are dug. The second disk has a slit-shaped through passage (0.1 mm width, 2 mm length, 2 mm depth) 25. By combining these two disks, a through-hole (0.1 mm × 0.1 mm) 26 is formed in the joint surface, which is smaller than the cross-sectional area of the groove-like passage entering from both the left and right in FIG. It is the narrowest place in the channel. The liquid containing the substance under pressure flows from both the left and right sides of the groove-shaped passage 24 and penetrates near the center in front of the through-hole 26 while acting as a wall where the liquids containing the substance do not wear each other. It will be bent at an angle towards the mouth.
If the rate after the rate before bending and V ₅ bends and V _6, towards the V ₆ from V ₅ is speed increases. V ₅ '· V
_The same applies to ₆ '. Since this speed change is performed within a short distance, the force applied to the liquid containing the substance becomes large. Furthermore, while shortening the distance from the bent portion to the through hole 26 and enlarging the passage after passing, the effect of acceleration is also promoted. After passing through the flow path, the particles are atomized and taken out from the accelerator and the pipe after passing through the accelerator to emulsify, disperse, and crush the substance.
