Abstract

1,140,774. Purifying liquids. COMPAGNIE ELECTRO-MECANIQUE. 12 Sept., 1967 [15 Sept., 1966], No. 41509/67. Addition to 1,056,130. Headings B1D. A settling tank, for machine tool coolant, comprises an inlet overflow 36, an endless scraper conveyor 40 and a floating assembly 50 which directs air jets on to the surface to blow foam, with entrained light solids, towards wall 37 up which they are carried, with heavy solids from the tank floor, by the conveyor, over lip 38. The scraper blades are serrated to allow liquid to drain back. The liquid is pumped from outlet 14, through a filter, which uses entrained foam as a filter aid' and has a continuous upstream side bleed back to the tank and also reverse flow cleaning, as described in Specification 1,056,130.
