なり、過作用が悪く不能となることが判つた。 Several types of filter devices are known that have a plurality of bodies each having a liquid guide hole in one piece. Their body is made by stacking pieces and matzas alternately, and their overaction is caused by the holes created between each of the countless fine particles layered on the outer periphery of the body. However, due to the rotation of the body, the fine particles stacked on the body surface may be forcefully and densely compressed and pushed into the grooves between each piece by the adjacent body piece, resulting in overheating. The fine particles that entered the grooves were laminated and hardened inside the grooves and were fixed there, causing a large torque on the body, which could result in failure or damage to the pieces. Therefore, as a means to prevent this, the inventor of the present invention attempted to eliminate the layered hardening of fine particles that have entered the grooves by widening the width between the pieces of each body, that is, the width of the grooves. However, although this achieves the purpose of preventing the laminated fine particles in the grooves from hardening, the fine particles cannot be removed in the grooves, and the particles directly come out of the system through the liquid guide hole, resulting in an overeffect. It turned out to be bad and impossible.

This is a grooved groove, and will be described below with reference to embodiment drawings.

出口１１ｂから連続的にでることになる。 The cake removal port 11b is closed with a lid C, and a suspension of the stock solution is supplied from the stock solution supply port 11a, and the whole body 2 is rotating in the same direction, and the water in the stock solution is guided through the passage groove 22a of the body 2. hole 25,
The fine particles are discharged to the outside of the system through the liquid chamber 12 and the liquid discharge port 12a, and are deposited on the surface of the body 2. Then, when the space between the two rows of bodies is filled with cake and the undiluted solution no longer comes out directly from the cake outlet 11b, when the lid C is opened, the cake will continuously come out from the outlet 11b.

この際の過作用は、体２の外周に積層する
ケークの各微粒子の間隙を過穴として行われ、
この過穴は体２の回転によるケーキの移動に
よつて常に再生されることになる。 The overaction at this time is carried out by using the gaps between each fine particle of the cake layered on the outer periphery of the body 2 as overholes,
This hole is constantly regenerated by the movement of the cake due to the rotation of the body 2.

ａの外へすくい出される。 Also, the over groove 22 is formed by the adjacent piece 21 of the body 2.
The fine particles that are forced into the inside of the groove 22
In the narrow part of the outer peripheral part a, it is compressed linearly inward and in a dense state, but in the enlarged overgroove 22a it expands and becomes coarse, so when the body 2 rotates, the piece 21 Due to overgroove 22
be scooped out of a.

その時、微粒子は液案内孔２５にも入ろうと
するが、量的には僅かであるので過作用には支
障がない。 At this time, the fine particles also try to enter the liquid guide hole 25, but since the amount is small, there is no problem with overaction.

硬化固定することがなくなる。 As mentioned above, by enlarging the inside of the body groove, the fine particles pushed into the groove due to the rotation of one piece of the cake layered on the body surface pass through the narrow part of the groove in a dense state. However, since it becomes rough in the enlarged area, the fine particles inside the groove are not hardened and fixed.
