ROTARY SCREEN DIVERTER AND SOLID WASTE HANDLING SYSTEM USING SAME

摘要

A solid waste handling system for screening and grinding solids entrained in an influent liquid stream flowing within a chute between laterally spaced vertical sidewalls utilizes at least one solids diverter horizontal rotating screen unit fixedly mounted within the chute and at an angle to the influent liquid stream with an endless loop open mesh screen mounted for rotation on a frame assembly such that one upstream face of the screen is vertical and moves horizontally across the stream in a direction towards the downstream offset grinder unit. The grinder unit has a housing with an upstream facing inlet port and mounts internally within the housing stacked interengaging shredding members for rotation about their axes in the path of flow of the solids bearing influent. Motors mounted to the units above the influent liquid stream level drive the screen and shredding members of respective units. Multiple screen units and multiple grinder units may be employed with the multiple screen units in stacked array, in end overlapping position, and with the endless screens driven to deflect solids towards one or more grinder units offset below the most downstream screen unit of the array.
