ABSTRACT:
A rotary filter for concentrating fiber suspensions comprises annular disks mounted in parallel and spaced from each other on a motor-driven drum having a lattice-shaped cylindrical wall, the drum being journalled in a vessel for liquid to be filtrated. Each filter disk is composed of sector-shaped filter boxes having at least two opposite filter walls and connected to outlet conduits included in the lattice-shaped wall of the drum. Further, a collecting hopper is stationary inserted in the drum to collect concentrated pulp falling down through the lattice-shaped drum wall from the filter surfaces at the moment such surfaces are in their uppermost positions.
