ABSTRACT:
A solid separator that uses a rotating screen, having spiral guides at its outer portion, over which a plurality of spiral-shaped scrapers are suspended. An inlet distributor including a plurality of apertures distributes a contaminated liquid flow over the screen, when rotated, permits the scrapers and guides to drive the deposited debris towards an outer edge of the screen and up a slight conical ramp and into a debris discharge sump. A level sensor may be included above the screen to activate the screen rotation based on the level of the contaminated liquid flow above the screen. An alternative embodiment uses individual scraper supports having respective jack mechanisms that permit the operator to independently lift and even rotate each scraper for additional cleaning or service. The alternative embodiment uses an assembly of two screens having an outer portion that also includes a slight conical ramp having spiral guides thereon.
