PURPOSE:To make the removal of screen-clogged solids easy by providing means of disposing a screen to the inner surface side of a frame at the anti-foaming and moving the same to the outer face side of the frame at the removing of the clogged solids. CONSTITUTION:A screen 2 is fixed to a ring 45 by way of a roller 41 on the outer side in the upper part of an outside cage 1 having the screen 2 on the inner surface side, and a cord 36 is fixed to the lower part of the ring 45. The other end of the cord 36 is fixed to a rotary plate 33 by way of the roller 47 and through-hole 37 in the lower part of the outside cage 1. When clogging occurs, the rotation is slowed down to lower a charging pipe 11 down to a predetermined position. This causes the rotary plate 33 to move upward, then the cord 36 lowers the ring 43 and the screen 2 slides downward on the outside surface of the outside cage 1 and turns over. When the outside cage 1 is rotated at a faster speed, the solids clogging the screen 2 are separated and collected into a casing 6. When the charging pipe 11 is returned again, the screen 2 also returns to the inner surface of the outside cage 1. |
