The ball-type snap-in connection comprises at least one ball pin and at least one coupling. An assembly comprising such a filter plate for a filter press and at least one attachment part, in which the attachment part is detachably fastened to the filter plate by means of at least one ball-type snap-in connection and has an opening which is arranged in the channel.

Abstract: A membrane for a membrane filter plate, having an elastic compression face and a peripheral fastening means. The membrane displays an elastic compression face and a peripheral fastening means. An opening for a fluid communication into a filter chamber is configured in the membrane. The invention furthermore relates to an arrangement of at least two filter plates of which one filter plate is a membrane filter plate having a membrane. One membrane is fastened on the first filter plate by means of the peripheral fastening means such that a compression means chamber is formed between the membrane and the first filter plate. The second filter plate bears on the first filter plate such that a filter chamber is formed between the compression face of the membrane and the second filter plate. At the periphery of the filter plates, a duct is formed between the filter plates.

Abstract: A filter plate having a basic body and an elastic element which is fastened to the basic body in an annular and liquid-tight manner. The filter plate is distinguished by the fact that a temperature-control plate is fastened to the elastic element.

Abstract: A filter plate for a filter press, having a main body and a diaphragm, on the periphery of which there is formed a fastening element, by means of which the diaphragm is fastened non-detachably to the main body, wherein an indentation is formed in the main body, said indentation at least partially accommodating the fastening element of the diaphragm, there being a welded connection between a fastening surface formed by the indentation and a fastening surface formed by the fastening element of the diaphragm.

Abstract: A chamber filter plate for a filter press includes a plate plane having a longitudinal direction and a crosswise direction. A plate body has a surface with a thickness. A plate edge frames the plate body and is thicker than the surface of the plate body. The plate edge has at least one hollow channel formed therein, extending in the longitudinal and/or crosswise direction. A method of producing a chamber filter plate is also provided.

Abstract: A leakage indicator is provided for a filter element of a filter press, in which the filter element has at least one membrane that can be impinged by a pressure medium. In order to create a leakage indicator that is constructed in a particularly simple manner, an indicator body is freely movable in a flow chamber. Any change in position of the indicator body, which is caused by inflowing or outflowing pressure medium, can be monitored visually or through the use of sensors.

Abstract: A membrane filter plate for a filter press includes a membrane fastened in the filter plate. The membrane has a flexible support layer, a central region with a functional layer different from the flexible support layer, and edge regions free of the functional layer.

Abstract: A filter panel contains a sludge inlet, a distributor ring which is arranged at the sludge inlet and has at least one inlet channel, and a support ring assigned to the distributor ring. A protective lip is mounted on the support ring and rests on the distributor ring in its closed position and partly covers the inlet channel.

Abstract: 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.
