An apparatus for draining sludge is assembled from a filter press with a ring-shaped press chamber (2) coupled with a piston pump (14) which feeds sludge from a reservoir to a forechamber (13) communicating with the press chamber (2). A reciprocating press piston (5) in the press chamber (2) is advanced for squeezing the sludge and on retraction opens a passage from the forechamber (13) to the press chamber (2). The piston pump (14) is coupled with the press piston (5, 11) in such a way that the pump (14) feeds sludge to the forechamber (13) at each retraction of the press piston (5). The press chamber (2) is surrounded by cylindrical filter walls (3, 4) and closed at the top of the press by means of a removable lid (6) which can be removed by parallel displacement in the direction of the central axis of the press chamber by means of an opening/closing mechanism. A drain (10) for liquid is led to the bottom of the chamber (8) in the inner filter cylinder (3). The press piston (5) is moved by a hydraulic mechanism. |
