ABSTRACT:
A rotatable filter assembly, primarily intended for separation of fibers from a fiber suspension, comprises a number of annular filter discs (3) formed by a plurality of filter elements (5). The filter discs are mounted on a horizontal drum rotatable in a container (1) and formed by axial discharge tubes (6) and transverse tubes (7) which communicate with the individual filter elements (5). A collecting hopper (8) extends into the drum through an open end of it. During at least part of the rotation of the drum, the interior of each filter element (5) is kept at a pressure lower than that prevailing at the outside of it. The filter assembly is characterized in that the axial discharge tubes (6), as seen in a cross-sectional view, are arranged in groups each comprising at least two tubes.
