ABSTRACT:
An automatic strainer assembly for straining a slurry comprises an inlet for receiving the slurry, a horizontally disposed strainer body in fluid communication with the inlet, and a rotatable strainer member received within the body having an inner surface and an outer surface. The strainer member defines a plurality of passageways for strained fluid to pass therethrough. A scraper is positioned substantially adjacent to and contacting the outer surface of the strainer member for removing material from the outer surface of the strainer member. A collection vessel is positioned substantially below the body for receiving material scraped from the outer surface of the strainer member. This collection vessel can include a transport member for returning this scraped material to an initial slurry supply for reprocessing thereof. An outlet is provided in fluid communication with the horizontal strainer body to expel the strained slurry.
