Abstract

545,913. Purifying liquids. DORR CO., Inc. Dec. 16, 1940, No. 17743. Convention date, Dec. 30, 1939. [Class 46] [Also in Group II] Liquid under treatment is supplied through perforated or slotted rotary tubular arms 24 to the lower part of a tank 14 and is agitated therein with reagent supplied by a pipe 63 and accumulated precipitate by blades 38, extending upward from the arms 24 and passing between baffles 41 depending from fixed supports 30. The layer of suspended precipitate extends above the top of the-baffles 41 and has a comparatively definite surface of separation from clear liquid above, which passes away over a launder 15. The blades 38 and baffles 41 are V-shaped in cross-section and arranged to avoid imparting vertical flow movement to the liquid. Excess of the suspended matter passes into a central hopper-like member 46, fitted with rotary scrapers 57, and is discharged through a pipe 58. The arms 24 are connected to a cylindrical member 23, which encircles the stationary end 22 of a feed pipe 21, as described in Specification 466,862. The member 23 is supported and rotated by a shaft 27 driven from a motor 20 on a platform 18 extending across the top of the tank.
