。Normally, in the production of paints, etc., after sufficiently dispersing a suspension with a high concentration of solid particles such as cough medicine, ie, Milpase, other components that do not need to be dispersed, such as resin solutions, solvents, additives, etc., are added afterwards. The final solution is mixed uniformly and used as a finishing liquid. Conventionally, in the production method like Jin, after dispersing the mill paste using a dispersion device as described below, the dispersed mill paste is taken out into a separate tank (R1), and components other than the mill base are subsequently added thereto and mixed by stirring. It was manufacturing finishing fluid.

昇降機構は設けられていない。Various types of dispersion devices as described above are known. In a device known as a "poly-mill," a dispersion medium and millpaste are placed in an inverted conical container, and a turbine blade is attached to the tip of a stirring shaft installed from above in the center of the container to drive the device. By rotating at (41), the mill paste is dispersed due to the frictional stress between the dispersion media. In addition, to deposit MilPase after dispersion, a turntable attached to the bottom of the inverted conical container is rotated at high speed using a drive device (Mo 2), and the centrifugal force acting inside the container is used to create a mixture of MilPase and the dispersion medium. The millpaste rises along the inner surface of the container, and only the millpaste flows out through a separator provided at the top of the container, and is separated from the dispersion medium. Furthermore, a drive device (grave 3) for raising and lowering the stirring shaft is provided. −
In the device known as the ``Sen+J-Mill'', the stirring shaft is installed from the bottom of the container and serves as the drive device for Mu 1 and Mu 2 of the ``Poly-Mill''. No elevating mechanism is provided.
上述の様な従来の分散装置においては容器そのものを分
散媒体とミルペースとの撹拌に供しているため下記の様
な欠点がある。In the conventional dispersion apparatus as described above, since the container itself is used for stirring the dispersion medium and millpaste, there are the following drawbacks.
（１）ミルペースの分散と仕上液の混合調整は別別の装
置となるため、設備が大きくなシ、またそれだけ広いス
ペースが必要である。(1) Dispersion of the mill paste and mixing and adjustment of the finishing liquid require separate equipment, which requires large equipment and a correspondingly large space.
（２）多量の分散媒体が必要であり、またミルペースと
分散媒体との分離が国難である。(2) A large amount of dispersion medium is required, and separation of the millpaste and the dispersion medium is a national problem.
（３）分散媒体の洗滌が困廟であシ、また媒体交換時の
取出しも面倒である゛。(3) It is difficult to wash the dispersion medium, and it is also troublesome to take it out when replacing the medium.
（４） 大きな撹拌駆動力を必要とする。(4) Requires large stirring driving force.
（５） 作動時における分散媒体と容器との衝突に起
因して騒音が大となル、容器の昇温か者しく更に容器の
損耗が激しい。(5) Due to the collision between the dispersion medium and the container during operation, there is a lot of noise, the temperature of the container increases, and furthermore, the container is subject to severe wear and tear.

After use, the dispersion medium sometimes enters between the bearing section at the bottom of the cage and the stirring shaft section that makes sliding contact with the bearing section, causing wear of the sliding joint.

A dispersion medium is housed therein, and the cage is provided with a large number of small holes large enough to prevent the passage of the dispersion medium, and inside the container there is a hole rotatable with respect to the cage. A stirring shaft that penetrates the cage and rotates in the vertical direction is provided, and the stirring shaft is provided with blades for stirring the medium inside the cage, and the above-mentioned shaft is provided at the bottom of the cage. The upper end surface of the bearing part for the stirring shaft is inclined so as to gradually become lower toward the outside, and the stirring shaft is provided with a shaft disposed close to the upper end surface of the bearing part for scattering the dispersion medium outward. A scattering piece is attached to the stirring shaft, and a blade for flowing the suspension is attached to the stirring shaft below the cage, and the percentage value indicates that the stirring shaft can move up and down together with the cage. This is accomplished by a dispersion device.

イド状懸濁液が得られる。The dispersion medium 6 and MilPase A are forcibly stirred in the cage body 2 by the rotation of the dispersion medium stirring blade 1O accompanying the 80 rotations of the stirring shaft, and abrasion stress is generated between the dispersion medium 6, which causes the particle size of the solid particles in the MilPase to change. becomes finer. At the same time, the Mill-Pace flow blade 110 rotates, and the Mill-Pace A that flows down from the bottom of the cage 2 flows to the surrounding area as shown by the arrow.
Move upward along the inner circumferential wall of the container l as shown by the arrow,
Furthermore, it flows into the cage body 2 from above the cage body 2 as shown by the arrow. Incidentally, when a cylindrical piece 13t in the shape of a crinkle is attached to the lower part of the cage body 2 as shown in FIG.
The flow of water is promoted and dispersion efficiency can be increased. Incidentally, if a small hole is provided on the side surface of the cage body 2, the MilPase 4 also flows out from this hole. In this way, under the continuous flow of MilPase A in the container 1, the dispersion of MilPase gradually progresses in the cage 2, and the desired colloidal suspension is finally obtained.

流出を十分に抑制することができる。In the dispersion device of the present invention, since the upper end surface of the bearing portion 20 is inclined outward as described above, the dispersion medium that arrives there immediately falls downward. Furthermore, as described above, since the scattering piece 24 is attached close to the upper end surface of the bearing, the dispersion medium that has arrived on the upper end surface of the bearing is immediately scattered outward. Due to the synergistic effect of these two, the dispersion medium 6 does not collect and deposit on the upper end surface of the bearing portion, and therefore the dispersion medium 6 enters between the sliding contact portion of the bearing portion 20 and the collar 22 of the stirring shaft 8. The frequency is extremely low, and it is possible to sufficiently suppress the outflow of the dispersion medium to the outside of the cage due to wear of this part.
