ABSTRACT:
A rotary pulp screening device of the horizontal type is disclosed having a high screening efficiency and high capacity. The screening device provides a streamline flow of pulp and one of its aims is to supply a fairly constant velocity of pulp along the length of the screen thus utilizing its full length. A cylindrical housing is included with a horizontal cylindrical screen therein, a rotary impeller mounted for rotation about a horizontal axis within the screen, the impeller having a body with an inlet end substantially in line with a fixed disc ring forming part of the housing, and an outlet end adjacent the upstream end of the cylindrical screen, the body having a shape with a circular axial cross section from the inlet end to the outlet end thus leaving a larger annular space at the inlet end representing an annular inlet between the disc ring and the body of the impeller, and impeller blades radiating from at least a portion of the body of the impeller and extending to within a short distance from the screen for the length of the screen. The improvement comprises at least one substantially frusto-conical shaped baffle, concentric with the body of the impeller, extending from the annular inlet, adapted to divide a flow of pulp entering the annular inlet and direct the divided flows to different locations along the pulp screen.
