Abstract

284,101. Marks, E. C. R., (Dorr Co.). March 7, 1927. Rotary filters.-In a rotary drum filter having filter sections arranged on its inner surface, each section is provided with a flexible filtering medium normally held to its support by suction but movable away therefrom into a flexed position to assist the discharge of the solid matter on application of fluid pressure within the section. A drum 1 having filter sections on its inner surface is mounted by a spider 2 and trunnion 3 in a fixed bearing 4 and by a spider 9, cylindrical extension 8 and a ring 5 on rollers 6, and it is rotated by means of a worm wheel 10 on the trunnion. Each filter section comprises a grid 16, Fig. 4, of wooden slats, a rigid wire screen 17 and a canvas or like medium 22, held in position by wedges 18 between the sections. Pulp under treatment is supplied by a pipe 14 and overflows from a trough 15 into a tank 12 into which the drum dips. Filtrate is withdrawn from the filter sections through pipes 28, 29, 30, the pipes 30 being connected to a valve of the type comprising a rotating plate 33 and a stationary plate 36, the latter having slots connected to a source of suction and ports connected to a pressure pipe 45. The cake is discharged from each filter section as it rises to its upper position by the application of pressure fluid which causes the filtering medium 22 to take a convex form. The medium is preferably subjected to pulsations at this point, a three-way valve on the pipe 45 being operated by worm and chain gear 53, 55 from the main worm driving shaft 11. The dislodged cake falls into a hopper 60 and is removed by conveyers 61, 69. The frame 63 of the conveyer 61 is supported at the inner end by a pivot pin resting in a bearing 65 in the spider 2. In a modified form of apparatus no tank 12 is used, the oil being retained in the drum which is closed at the inner end and has a deep annular flange at the other, the cylindrical extension 8 being omitted and the ring 5 being fixed on the end of the drum itself.
