Abstract

711,944. Filters. NORDELL, C. H. Oct. 30, 1952 [Dec. 17, 1951], No. 27340/52. Class 46. [Also in Group II] Apparatus for screening solids from a liquid comprises a stationary screen through which the liquid flows, a rotatable cylinder spaced from the front of the screen, tines carried by the cylinder, and mechanism for advancing and retracting the tines relatively to the cylinder as the latter rotates such that the tines are fully advanced as they sweep past the screen to cooperate with the screen and remove solids therefrom and transfer these solids to a place away from the screen, and are fully retracted when they are remote from the screen. The screen comprises flat metal ribbons 25, Fig. 1, in slots 20, 23 and held taut individually by springs 31 connected to short strips 28 in slots 24. Solids collecting on the influent (right-hand) side of the screen are removed by tines 79 secured to a bar 95, Fig. 8, within a cylinder 82 rotating anticlockwise, and are carried up to a comb 89 where they are comminuted by co-operation of teeth 87, on cutting members 86 secured between spacers 84 on the cylinders 82, with recesses 94 on the comb. The bar 95 is pivoted between crank arms 99 (one at each end of the cylinder) each rotating about a bolt 103, the arrangement being such that when one set of tines 79 is fully advanced and engaged between the ribbons 25, the other set 79a is fully retracted and located opposite the slots 94. Fig. 8 shows an intermediate position. The cylinder is driven through worm gearing by a motor 59, Fig. 1. Nozzles may be provided in a pipe extending along the frame member 9 for supplying air or water to force solids up the screen to the tines. In a modification (not shown) the cutting members 86 and comb 89 are omitted, the solids being removed from the cylinder at the top by a stripper plate from which they fall onto a transversely-moving conveyer belt for discharge outside the channel 3.
