Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for atomizing substances handled in the food, chemical, pharmaceutical and other industries, and more particularly,
The present invention relates to an apparatus for atomizing a substance in a state of emulsification, dispersion or crushing into a uniform (or homogeneous) particle size on the order of microns or less to obtain a stable particle size distribution.

[0002]

2. Description of the Related Art As a conventional atomizing device for substances, there is a device disclosed in Japanese Patent Laid-Open No. 2001-29776, which was recently published. This is a material atomization device that pressurizes the raw material supplied to the raw material supply port and sends it to the main body of the device, and atomizes the substance in the raw material by this main body, in which the main body is a cylinder with an inlet and an outlet. A body and at least two discs which are mounted on the cylinder so as to be flush with each other, and each disc has a large number of through holes aligned in the same or similar manner, and on the face. A large number of grooves for connecting the respective through holes are provided, and in the above-mentioned lecture, the grooves of one disk are arranged at a large number of positions in a state where the respective disks are overlapped with each other and the surfaces of the grooves are the same as the grooves of the other disk. It is characterized by intersecting with each other above.

This conventional device has an advantage in that it is possible to perform a desired amount of atomization processing without increasing the processing pressure so much due to the above structure.

[0004]

However, although the above-mentioned conventional device has the above-mentioned advantages, when the device main body is downsized, since each disk has a large number of through holes, the manufacturing process is difficult. There is a drawback that. On the other hand, if the number of through holes and grooves is reduced as much as possible, processing becomes easier.
There is a drawback that the flexibility and the degree of freedom in design cannot be satisfied because the industry does not meet the particle size requirements for atomization in each industry that handles substances.

According to the present invention, the apparatus can be downsized, the manufacturing process can be easily performed, and various requirements such as an increase in the treatment particle size and the treatment amount of various substances can be appropriately dealt with, and the versatility, versatility, and It is an object of the present invention to provide an atomizer for a substance which is satisfactory in terms of design freedom.

[0006]

In order to achieve the above-mentioned object, the present invention relates to claim 1 in which a raw material supplied to a raw material supply port is pressurized and sent to a main body, and the main body finely granulates the substance in the raw material. In the atomizer of the substance to be atomized and taken out, the main body has a cylindrical body with an inlet and an outlet, and a pair of discs A and B which are aligned with the cylindrical body and are superposed on the P plane and flush with each other. However, the disks A and B are respectively provided with two through holes in semicircular portions on the opposite sides, and the P surface of either one of the disks A and B has two through holes. Is provided with a groove having a predetermined shape which is connected to the through hole and is symmetrical with respect to the horizontal diameter line XX and the vertical diameter line YY. When the disks A and B are stacked on the P plane, both ends of the groove are formed. The portion is adapted to communicate with the other two through holes, and the second aspect is to supply the raw material supply port. In the atomizer of the substance, which pressurizes the raw material and sends it to the main body, and atomizes the substance in the raw material by this main body, the main body is a cylindrical body with an inlet and an outlet, and a surface aligned with the cylindrical body. A pair of discs A and B which are superposed and assembled on the P plane
Has 2 to 6 through holes which are symmetrical with respect to the horizontal diameter line XX and the vertical diameter line YY and do not overlap each other, and these through holes are provided in the P plane of each disc in the P plane. Are connected by a linear groove, and when the disks A and B are overlapped with each other on the P plane, both of the grooves intersect each other at 1 to 5 intersections K so that they communicate with each other. It is a feature.

[0007]

According to the first aspect of the invention, the raw material (fluid) flowing into the two through holes in the upper half circle of the disk A collides with the P surface of the disk B and then changes its direction at a right angle. , For example, through a figure-eight groove and communicate with two through-holes in the lower half circle of the disk B at both ends of the groove, and turn here again at right angles, and from this through-hole Flow away. In these flows, the substance in the pressurized fluid is atomized into particles having a desired particle size (determined by the particle size distribution) by merging collisions in through holes, grooves, etc. and diversion expansion. Even if the material of the disc is ultra-hard ceramic, sintered artificial diamond or single crystal diamond, and the size of the hard disc is 40 mmφ in diameter and 5 mm in thickness, it is easy to perforate holes with a diameter of 1-2 mmφ. 0.5 mm
A groove with a width of 0.2 mm can be processed. By changing the hole diameter and the shape of the groove, it is possible to meet the demand for increasing the particle diameter and the flow rate (processing amount).

In the second aspect, for example, the raw material flow equally distributed into the four through holes of the disk A hits the P surface of the disk B and changes its direction at a right angle, so that the H of the disk A is changed. After entering the groove of the shape and colliding with each other at the center, at the intersection K (one in this case), this time into the groove of the shape of disk B, split at right angles to both, From each of the through holes, it turns again at a right angle and flows out. In this case, as the number of through holes is large, it is rich in flexibility, and accordingly, processing becomes difficult,
Since the position and the number of the through holes are defined, it is possible to reduce the difficulty of processing. By changing not only the hole diameter and number of the through holes but also the size and shape of the grooves, it is possible to meet the demands for the particle diameter.

An atomized product, that is, a receiver for atomized products.

FIG. 2 is a cross-sectional view of the main body 3 in FIG. 1, and the main body 3 is positioned in one cylindrical body 5 formed by fastening a cylinder 6 on the inlet side and a cylinder 7 on the outlet side with bolts 8. It has a pair of discs A10 and B11 which are aligned by a pin 9 for use and are mounted so as to be flush with each other on the P-plane. Disk A,
Both B are made of ultra-hard ceramics with a diameter of 40 mm and a thickness of 5 mm.

In the present invention, the pair of discs A and B correspond to claims 1 and 2 described in the claims, and the embodiment has a first form and a second form. Divided into

[First Embodiment] FIGS. 3 to 7 show the first embodiment of the first embodiment. FIG. 3 is a perspective view schematically showing a state before the disc A10 and the disc B11 are brought together on the P surface. In FIG. 3, the disk A10 has a lateral diameter line XX.

(See FIG. 4). Also,
The disk B11 does not have any groove on the P surface, and has two through holes (disks) at a position symmetrical with the through hole 12 of the circle A10, that is, in the lower semicircle below the lateral diameter line XX. A diameter of about 2 mm φ) 14 which is slightly larger than that of A is provided. (Refer to FIG. 6 showing the P surface of the disk B). The through hole 14 communicates with both end portions 13A of the groove 13 when combined with the disc A10. It should be noted that in FIGS. 3, 4 and 6, reference numeral 15 is a hole which is fitted into the pin 9 for positioning.

The operation of the first embodiment of the first mode is as follows. That is, in FIG. 3, assuming that these are assembled as shown in FIG. 2, the raw material flow (shown by the arrow D in FIG. 3) entering the through hole 12 of the disk A10 is the disk B.

It is bent again at a right angle and flows out (indicated by arrow E).

As a result, the substance in the raw material is atomized to a desired particle size by collision with high pressure and high speed flow, merging, diversion and expansion. Both discs A and B have a small number of through holes, and since disc B is not provided with a groove, it is easy to process and has the advantage that it can be miniaturized as much as possible.

8 to 10 show a second embodiment of the first mode. As shown in FIG. 8, the disc A10 has a vertical diameter line Y.
There are two through holes 12 in the right semicircle of Y, and a groove 13 that is connected to these through holes 12 and has a V-shape and an inverted V-shape that are symmetrical with respect to the horizontal diameter line XX and the vertical diameter line YY is formed. It is provided. On the other hand, as shown in FIG. 10, the disk B11 has two through holes 14 at the same position as the disk A10 in the right semicircle of the vertical diameter line YY, but with a slightly larger hole diameter. , B when the positioning holes 15 are overlapped with each other, the semicircular portion having the through hole 14 becomes the left semicircular portion as shown by the chain line in FIG. It is in communication.

11 to 14 show a third embodiment of the first mode. As can be seen from these figures, the positioning hole 15 is located above the longitudinal diameter line YY for both the disk A10 and the disk B11, and the two through holes 12 and 14 are both located in the left semicircle. , They are located in opposite semi-circular portions when they are overlapped with each other, and the groove 13 has a shape in which W-shaped and inverted W-shaped are stacked as shown in FIG. It is symmetric with respect to the line and its both ends 13
A communicates with the through hole 14.

As described above, in the first embodiment, the flow rate increase can be dealt with in the order of the first embodiment, the second embodiment, and the third embodiment, and the numbers of the through holes of both the disks A and B are mutually different. Since only two are provided in the opposite semi-circular portions, it is easy to manufacture and process with a small size.

The disk B21 is provided with two through holes 24 having a height h and a slightly larger diameter, and a single linear (I-shaped) groove 25 which is slightly wider and connects these holes along the longitudinal diameter line YY. (See FIG. 18). When the disks A and B are overlapped with each other with the positioning hole 26 as a reference, the two through holes 24 are positioned in the middle of the four through holes 22 and do not overlap each other, and the groove 25 and the groove 23 are not overlapped. Intersect with each other at one intersection K, and they communicate with each other.

Next, in the second embodiment shown in FIGS. 20 to 23, the numbers of the through holes 22 of the disk A20 and the through holes 24 of the disk B21 are the same as those of the first embodiment, but the arrangement is changed. The height H and the hole diameter are increased, and the groove 23 and the groove 25 that connect them are also wide.
Moreover, the groove 23 of the disk A20 has five horizontal lines, which allows the intersection K to intersect with the groove 25 of the disk B21.
Is also 5 pieces. As a result, the second embodiment can cope with an increase in the flow rate as compared with the first embodiment.

Further, in the third embodiment shown in FIGS. 24 to 27, in the disk A20, the through holes 22 have a hole diameter smaller than that of the second embodiment, but the number is six, and the disk In B21, the number of the through holes 24 is four, which is two each. Both of them are arranged with a height H and a width m, but of course, both through holes do not overlap each other. When the disks A and B are overlapped with each other with the upper positioning hole 26 as a reference, the intersection K between the groove 23 and the groove 25 is shown in FIG.
As shown in FIG. 4, ten horizontal lines make a total of ten, which makes it possible to cope with a further increase in the flow rate.
