A filter for thickening fibrous stock suspensions comprises:- a) at least two hollow shafts (4, 5) arranged parallel and adjacent to each other in a common filter trough (3), b) a row of hollow filter discs (6, 7) attached to each hollow shaft, the discs on the respective shafts intermeshing between each other, c) discharge chutes (18, 19) located beneath and extending between the discs on the respective shafts to receive filter cake therefrom. Shafts (4, 5) are connected to suction chambers (12, 15) receiving cloudy and clear filtrate from different sectors of the discs, and clear filtrate is recycled to nozzles (22--24) to spray the filter cake off the discs. <IMAGE> |
