The invention relates to a filter plate for a plate-and-frame filter press. The filter plate comprises a filter plate main body, a fixing part and a cloth rolling mechanism, wherein the outer side edge of the four-edge frame of the filter plate main body is provided with a filter cloth fixing structure; the cloth rolling mechanism comprises a rotating shaft, a detachable connecting structure and a connecting piece, and the detachable connecting structure is detachably connected to the outer side edge of the frame of the filter plate main body; the rotating shaft is arranged on the detachable connecting structure, and rotates under the action of outside force; and one end of the connecting piece is connected to the rotating shaft. The cloth rolling mechanism is arranged to stretch the filter cloth in order to effectively offset shrinkage deformation caused by shrinkage of the filter cloth, so the service life of the filter cloth is greatly prolonged, thereby subsequent frequent replacement of the filter cloth is avoided, the running cost is saved, and repeated long-term use is realized.
Description
technical field [0001] The invention relates to the technical field of plate and frame filter press devices, in particular to a filter plate for a plate and frame filter press. Background technique [0002] Plate and frame filter press is a kind of intermittent solid-liquid separation equipment, which has the characteristics of lightness, flexibility and reliability. Under the action of the material pump, the material liquid is transported to each filter chamber, and the solid and liquid are separated through the filter medium (filter cloth). Compared with other solid-liquid separation equipment such as centrifuges, plate and frame centrifuges have the advantages of low investment, power saving, safety, etc., and are widely used in chemical, dye, petroleum, ceramics, medicine, food, smelting and various industries sewage treatment, etc. [0003] In the prior art, the main structure of the plate and frame filter press includes the following, which includes a bracket, two be...
