Abstract
A filtration-compression type filter press comprising a fixed end plate and a movable end plate and compression filter plates suitably disposed therebetween. Each compression filter plate comprises a base plate having a central opening larger than a slurry feed port and a filter compression diaphragm in the form of two flexible fluid-tight sheets applied to the front and rear surfaces of the base plate and having uneven filter surfaces with a filter cloth piece applied thereto. The diaphragm is integrally formed with a cylindrical portion interconnecting the sheets and extending through the opening in the base plate to define the slurry feed port. A pressure chamber is formed between the base plate and each of the sheets. The compression filter plate has a pressure fluid feed channel communicating at least with the pressure chamber and a filtrate outlet channel open to its filter surface. A ring radially divided at least at one portion for preventing the displacement of the filter compression diaphragm relative to the base plate is fitted in the base plate opening around the cylindrical portion and held to the opening-defining inner periphery of the base plate axially thereof.
