Separating and clarifying plant for water containing mineral materials such as sand and gravel, has tank with scoops on rotating wheel connected to endless screw

摘要

A separating/clarifying plant, comprising an endless screw to remove coarse materials and a treatment unit, includes a tank to receive the contaminated liquid containing a driven rotary wheel with scoops on radial arms that raise the liquid from the bottom of the tank and discharge it at the top into the endless screw via a hopper. The hopper is located at the lower end of the endless screw and has one wall that acts as an overflow for the liquid. The separating/clarifying plant, comprising an endless screw to remove the coarser materials and a treatment unit, includes a tank (1) to receive the contaminated liquid containing a driven rotary wheel (13) with scoops (16) on radial arms (15) that raise the liquid from the bottom of the tank and discharge it at the top into the endless screw via a hopper. The hopper is located at the lower end of the endless screw and has one wall that acts as an overflow for the liquid. The top of the tank is located at ground level, and it has an overflow linking it to a second tank with pumps.
