Solids concentrator with a rotor having ploughs thereon

Abstract

The concentrator has at least one shaft-mounted rotor disc of solid or hollow construction with two or more ploughs located equally spaced about its periphery. The ploughs extend outwardly into the flow path of a solids-containing fluid within the concentrator to deter any tendency, due to centrifugal force, for a build-up of solids between stationary filter means and in a region remote from the periphery of the rotor disc. In a disclosed embodiment of the concentrator, the shaft-mounted rotor disc has at least one passage therethrough for the flow of solids-containing fluid from one side of the rotor disc to the other, and a plough is provided adjacent the passage and on a hub of the rotor disc to deter any tendency for a build-up of solids adjacent the passage. Further, in a disclosed concentrator with stationary filter means of annular construction wherein the inner edge of the annular filter means is spaced from a rotor shaft or hub thereon, a plough extending toward the rotor shaft is provided on the inner edge of the filter means.
