ABSTRACT:
A filter device for separating a foreign material-liquid mixture into distinct portions includes a holding tank. On a bottom of the tank is a permeable grid panel formed with a series of elongated corrugations. The panel connects with an impermeable inclined ramp formed with corrugations of a like configuration. A conveying device carried within the tank comprises a pair of spaced chain loops to which are connected a series of transversely positioned flights. Each flight includes a scraper plate having a corrugated edge which complementally mates with the corrugations of the grid panel and inclined ramp. As the liquid portion of the mixture flows through the grid panel, the foreign material is retained and collects to form a cake on the panel. Periodically the conveyor is activated. The scraper plates move over the grid panel corrugations to remove the collected foreign material and move the foreign material up the inclined ramp for disposition external of the tank.
