ABSTRACT:
A filter for separating material of greater density from material of lesser density, comprises a hollow body having an inlet at one end thereof for the materials to be separated, and outlets at the other end thereof for the separated materials. A passage joins the inlet to the outlets and has two sets of separator vanes disposed therein. Alternatively, a single set of separator vanes is disposed in the passage. Each set of vanes is positioned in the passage so as to define a first, convergent flow path for the material of greater density. The vanes in each set are spaced longitudinally of the passage such that a plurality of second, divergent flow paths for the material of lesser density are defined between respective pairs of adjacent vanes. Each vane has an upstream edge, a first surface portion extending from the edge in a downstream direction and facing in an upstream direction, and a second surface portion which is concave and which faces in the downstream direction. The first and second surface portions are joined by a junction, and the junction of the upstream vane of each pair of adjacent vanes is disposed so as to mask the second flow path defined between that pair of vanes with respect to the longitudinal direction of the passage. In this way, the material of greater density is prevented from passing through the second flow paths.
