ABSTRACT:
The thermoplastic filter plate is designed for a filter press comprising a plurality of the filter plates clamped together edgewise forming a plurality of filter chambers between themselves. Each filter plate has a press wall on one or both sides of it. This press wall is at least flexible in an edge region and is movable by action of a pressurizing medium into one of the filter chambers. Each of the filter plates includes unitarily a supporting wall and a compression chamber for the pressurizing medium acting on the press wall, the supporting wall being located between adjacent compression chambers. The press wall is made in one piece with a plate frame of the filter plate. The rigid plate frame is composed of a hard plastic material resistive to the closing pressure of the filter press and the press wall is composed of an elastic plastic material guaranteeing an easy adjustability and deformability.
