ROTARY SCREEN DIVERTER & SOLID WASTE HANDLING SYSTEM USING SAME

摘要

There is described an improved solid waste handling system for screening and grinding solids entrained in an influent liquid stream that utilizes at least one solids diverter horizontal rotating screen unit fixedly mounted in the liquid stream such that the flow moves through it and that is partially immersed in the influent liquid stream. The screen unit comprises a rigid frame assembly and a screen member mounted for rotation on the rigid frame assembly such that the screen member moves horizontally relative to the liquid stream. The screen is rotated to cause solids of the influent stream larger than openings in the screen to impact upon an upstream face of the screen to be moved horizontally in the direction of screen movement to one side of the liquid stream. A solid waste grinder is fixedly mounted adjacent to the screen unit whereby solids diverted from the influent stream are conveyed from the screen to the solid waste grinder and finely ground prior to discharge through an outlet of the solid waste grinder.
