1. A filter press, comprising a housing (2, 4, 14) having a pulp inlet and end walls (2, 14), and comprising a casing (4) supported in a frame (2, 3), said casing having an interior cavity of substantially circular cross-section and forming a chamber for receiving the pulp to be filtered, further comprising a plurality of filter units (5) coaxially aligned within said housing (2, 4, 14) one behind the other and composed each of a filter frame (6) mounted in said frame (2, 3) and defining a filtrate chamber (31) covered in a radial plane by a filter medium (28), an annular clearance (33) being formed between said filter units (5) and said casing (4), and further comprising a discharge pipe (10) extending through the interior of the filter press in a substantially axial direction, said filtrate chambers (31) being in communication therewith, and including means for relatively moving the casing (4) on one hand the frame (2, 3) and at least one of said end walls (2, 4) on the other hard in axial direction with respect to each other, characterized in that a rotor disk (7) is disposed between each two filter units (5), facing the filter media (28) of the adjacent filter units (5), all said rotor disks (7) being non-rotatably mounted on a common hollow shaft (8) extending centrally through said housing (2, 4, 14) and said filter units (5), means (19 ; 50, 44, 48) being provided by which the radially extending surfaces of said rotor disks (7) may be moved towards the filter media (28), and that said filter frames (6) are supported independently of said casing (4), said frame (2, 3) and both end walls (2, 14) are fixedly disposed, said casing (4) being mounted so as to be axially displaceable with respect to said end walls. |
