Abstract

411,900. niters. ROBISON, C. S., 1255, North State Street, Chicago, U.S.A. Dec. 14, 1932, No. 35482. Convention date, Dec. 14, 1931. [Class 46.] A rotary suction drum filter is divided by radial partitions into compartments 17 each of which has a draining grid 21, with a longitudinally-extending inwardly-projecting nozzle 23 the walls of which are inclined so as to provide pockets with the walls of the compartment such that residual liquid is collected therein, as the compartment passes to its lower positions during rotation of the drum, and is not allowed to return to the cake on the drum. As shown in Fig. 1 each nozzle is divided into two portions by intermediate walls 26<a>. The drum is supported on hollow trunnions 11, 12. The inner end of the compartments is closed by a conical member 19 which has a cylindrical extension 19<a> within the trunnion 12, the space between the extension and the trunnion serving to connect the compartments with a casing 20, which has a connection 20b to a fan or suction blower and an outlet 20<a> for the filtrate. The material under treatment can be supplied to the drum by a trough 33 and chute 34, which are mounted so that they can be tilted together to regulate the supply. A dam 39 is arranged in front of the end of the chute. The main portion of the cake is removed from the drum by scrapers 45 on rods 47, which can be turned to adjust the distance of the scrapers from the drum. The cake falls into a hopper 42 and is discharged. by a conveyer 44. There is a final scraper 52 and a pipe 54 for the supply of wash water. Heated air is supplied at the sides of the drum through housings 56 with heater pipes 57. The draining grids 21 support a filtering- medium which may be of canvas, or wire-mesh.
