classification Plate frame Filter Press 1, the plate and frame filter press (plate and frame filter press) consists of a set of filter chambers which are alternately arranged with filter plates and filter frames. The surface of the filter plate has grooves, and the convex part thereof is used for supporting filter cloth. There is a through hole on the side of the filter frame and filter plate. After assembly, it forms a complete passageway, which can pass into suspension, washing water and filtrate. Each side of the board and the frame is supported by a handle on the cross beam, and the pressing device is pressed on the plate and frame. The filter cloth between the plate and the frame plays the role of sealing gaskets. From the feed pump, the suspension hydraulic filter enters the filter chamber to form a filter residue until the filter chamber is filled. The filtrate passes through the filter cloth and flows along the filter plate trench to the edge and corner channels of the frame and plate, and then is discharged centrally. After filtration, the filter slag can be washed through clean water. After washing, sometimes the compressed air is added to remove the remaining washing liquid. Then the filter press is opened and the filter residue is removed, the filter cloth is cleaned, the plate and frame are pressed again, and the next working cycle is started. 2. The plate and frame filter press can be applied to the suspension with high compressibility and near incompressible suspension. The solid suspension concentration of the suitable suspension is generally less than 10%, the operating pressure is generally 0.3 to 0.6 MPa, and the special can reach 3 MPa or higher. The filter area can be increased or reduced with the number of frames used. The frame is usually square, the inner side of the filter frame is 200~2000 millimeters, the frame thickness is 16~80 millimeters, and the filtration area is 0.5 to 1200 square meters. Plate and frame are pressed by manual screw, electric screw and hydraulic pressure. Boards and frames are made of wood, cast iron, cast steel, stainless steel, polypropylene and rubber.
