Description

Technical Field

[0001] The present application relates to the technical field of filter presses, and in particular to a filter plate of a filter press. Background Art

[0002] The function of the filter press is to achieve solid-liquid separation. The main filter element in the filter press is the filter plate, and the filter chamber is formed between adjacent filter plates. After the material enters the filter chamber, the solid component is intercepted by the filter cloth coated on the surface of the filter chamber to form a filter cake, and the filtrate is discharged from the liquid outlet at the bottom of the filter plate, thus achieving solid-liquid separation of the material.

[0003] In the related art, feeding is usually carried out in the middle. For example, a patent with publication number CN220758115U and publication date 2024-04-12 discloses a compressible filter press filter plate, including an outer frame made of metal, a water-permeable trough plate welded in the outer frame, and a feed hole is arranged in the middle of the water-permeable trough plate.

[0004] When the middle feeding method is adopted, the slurry tends to concentrate in the middle of the filter plate, resulting in low filtration efficiency in some areas of the filter plate, thus affecting the overall filter pressing efficiency. Utility Model Content

[0022] By adopting the above technical solution, the driving handle is rotated, and the driving handle drives the rotation of the main pulley, and then drives the rotation of the slave pulley through the belt, so that the two rotating rods rotate synchronously.

[0023] Optionally, the driving component further includes:

[0024] A tensioning block, slidably connected to the filter plate;

[0025] A tensioning pulley, rotatably connected to the tensioning block, for tensioning the belt;
