There is an apparatus that performs dispersion by mixing a large number of dispersion media and forcibly stirring them. However, in such conventional dispersion devices, forced agitation is performed by rotating a drive shaft equipped with multiple disks in one direction in a closed container, so the MillPace and medium flow in the same direction and are not dispersed. Efficiency is not very good. In addition, since stirring is performed in a sealed state, the internal pressure increases due to the liquid flow, and it is necessary to install a sophisticated sealing mechanism around the rotation axis to prevent liquid leakage. It is necessary to encapsulate or circulate the liquid. Furthermore, some conventional dispersion devices separate the dispersion medium and the dispersion liquid using a screen attached around the rotating shaft, but in this type of system, the area through which the dispersion liquid passes is small and internal pressure is applied, making it difficult to disperse. Significant wear of the screen by the media.

れる。When using the above-mentioned dispersion device, first put an appropriate amount of dispersion medium 7 into the dispersion container 1 from the dispersion medium inlet 24 (of course, keep the dispersion medium outlet 25 closed), and then close the dispersion medium outlet 25. The container is closed, and while cooling water is passed through the cooling water passage 21, MilPase is fed into the container 1 from the MilPase feeding section 8. At the same time, the drive means 3 rotates the rotary shaft 2, thereby rotating the disk 4 and the screen 5. At this time, the rotating shaft 2 is driven so that the direction of propulsion of the screw 5 is directed toward the millpaste feeding section 8. Moreover, the position adjustment means 1
3, the medium passage blocker 12 and the partition wall 1
1 to form a gap large enough to prevent passage of the medium. The millpace and medium 7 in the container 1 are transferred to the disk 4
is stirred and moved in the circumferential direction,
It is caused to move in a linear direction by the screw 5 so as to be returned to the milpace feed section 8. This scree-5
acts more efficiently on the medium 7 than on the mill-pace, thus preventing the medium 7 from proceeding towards the dispersion outlet 9 and ensuring a substantially homogeneous distribution of the medium 7 in the dispersion vessel. do as you like. Therefore, the medium 7 is not collected and retained on the dispersion liquid discharge part side, and the relative momentum between the mill paste and the medium 7 is also increased, so that the dispersion efficiency is improved. Part of the dispersed liquid passes through the porous body 10 and enters the front chamber 9a, and the other part passes through the gap between the blocking body 12 and the partition wall 11 and enters the rear chamber 9b. Front chamber 9a and rear chamber 9b
The dispersion liquid inside is taken out from each outlet to the shooter 20 and collected. In this device, the dispersion liquid discharge part 9 is open to external pressure, so the pressure near the discharge part in the container 1 does not increase much, and therefore the sealing mechanism in the discharge part 9 is relatively simple. good. Further, in this device, the dispersion liquid from the container 1 is discharged into the front chamber 9a and the rear chamber 9b with a relatively large liquid passage area, so that the medium 7 and the dispersion liquid are smoothly separated.
以上の如く、本発明分散装置によれば、比較的簡単な機
