Patent attributes
The invention relates to a membrane filter press. On operation of such a press a secure generation of the necessary pressing pressure can be guaranteed with a membrane filter press that has at least one membrane filter plate, a baseplate with thickened edge region, a membrane made from an elastically-deformable material, and a filter cloth. The novel membrane has an annular edge bead which lies in a complementary groove on the baseplate. A sealing groove is formed into the baseplate which opens out into the first-mentioned groove at both ends in the manner of a bypass. A complementary sealing projection, moulded on the annular bead, engages in the sealing groove with formation of a seal. The cavity enclosed between the groove and the sealing groove is preferably provided with at least one filtrate drain bore.
