除去するフローテーターが主として使用されている。[Prior Art] Conventionally, in waste paper treatment, a flotation method has been used, which has the advantage of less fiber loss and less water usage, in order to separate and remove fine light foreign matter such as ink peeled from fibers from the raw material. However, a floatator that is attached to air bubbles and floated to be removed is mainly used.

仕切室27から流出するようになっている。In a conventional floater, for example, as shown in FIG. 3, an inlet 22 for raw material and air is provided in a lower portion of a tank 21, and the inlet 22 is covered with a box 23 having a large number of through holes. The impeller 24 is rotatably installed in the
By rotating 24, the bubbles are finely divided and sufficiently mixed with the raw material and dispersed in the tank 21, and the bubbles are preferentially floated to the liquid surface by utilizing the speed difference between the rising speed of the raw material and the floating speed of the bubbles. At the same time, fine light foreign matter such as ink is attached to the air bubbles, and this is discharged to the outside of the tank by the rotary scraper 25, and the raw material from which the foreign matter is removed is partitioned by the overflow wall 26 in the tank 21. It is designed to flow out from the partition room 27.

It floats and at the same time removes ink etc. by adhering it to the air bubbles. Therefore, the liquid surface is often open to the atmosphere, and it is difficult to say that the material and air bubbles are sufficiently separated, and the environment around the floater is bad.

送入することもできる。In the present invention, the material containing the peeled ink and other light foreign matter is supplied into the drum through an inlet at one end of the drum which rotates at high speed together with air. The air is supplied in such a shape that a low pressure part is formed by the flow of the raw material flowing through the raw material supply pipe, and the air is sucked into the low pressure part by a so-called ejector method. However, it is also possible to force the air to be blown in by using a blower or the like.

の偏向部材の周囲を経て原料出口から回収される。The raw material and air supplied into the drum are swirled by the high-speed rotation of the drum, and are further swirled inside while being deflected toward the inner wall of the drum by the deflecting member. The raw material gathers on the inner wall of the drum by the centrifugal force generated by the swirling flow. At the same time, the air bubbles are collected on the rotating shaft portion in the drum and are naturally taken out from the foreign substance taking-out pipe communicating with the rotating shaft portion due to the pressure difference with the atmosphere, or sucked and taken out by a vacuum pump or the like. At this time, the light foreign matter including the ink flows toward the center of the drum and is taken out along with the flow of bubbles. On the other hand, the raw material from which the light foreign matter has been separated and removed is recovered from the raw material outlet via the periphery of the deflecting member on the outlet side.
