Abstract

888,304. Filters. IBIS ENTERPRISES Ltd., and BIRD MACHINE CO. Aug. 4, 1960 [Aug. 17, 1959], No. 27120/60. Class 46. A screening device includes an annular chamber formed by a pair of concentric spaced walls 12, 14, with an inlet 36 for a stream of liquid suspension adjacent one end, an outlet 56 for accepted stock, and an outlet 18 for rejected suspension from a circular trough 16, at the other end of the chamber, and a plurality of hydrofoils for cleaning the fixed cylindrical wall 22, or walls 20, 22, of the single or double screen respectively and rotated on a ring, Fig. 3 (not shown), and is characterised in that a portion of the outer wall 14 of the chamber is formed by the screen wall 22, and the chamber contains an outlet 28 for continuously withdrawing a portion of the suspension, containing the heavier particles, without it passing through the screen. A stream of liquid is introduced through a supplementary inlet 54, to dilute the suspension and facilitate the final stages of screening before the accepted stock is passed through the outlet 56.
