[0002] The plate and frame filter press is a very mature dehydration equipment, commonly used for separation of solids and liquids. Compared with other solid-liquid separation equipment, the mud cake filtered by the filter press has a higher solid content and excellent separation effect. For example, a plate and frame filter press with Chinese patent application number CN202321833181.7 includes a bottom plate, universal wheels are installed at the four corners of the bottom of the bottom plate, support columns are installed at the four corners of the top, a mud collection and processing component is fixedly installed in the middle of the top, an L-shaped fixed plate is installed on the top of the support column, and a plate and frame filter press component is provided at the bottom of the inner wall of the L-shaped fixed plate, and the filter press is driven to move by the universal wheel. When it reaches a suitable working position, the electric telescopic machine drives the adjusting plate to move, and at the same time drives the mud scraper to move downward to scrape off the mud blocks attached to the plate frame. The scraped mud blocks fall into the mud treatment collection box at the bottom, which is convenient for subsequent unified treatment. When processing the mud blocks, the electric lifting rod is started to drive one end of the mud treatment collection box to move downward in an inclined shape, which is convenient for the mud to slide out quickly and improve the mud block processing efficiency. The water is transported to the cleaning nozzle through the water pump assembly and sprayed out, which is convenient for cleaning the plate frame.

[0039] The working principle of the plate and frame filter press is as follows: first, the hydraulic cylinder 130 pushes the push plate 140 so that the multiple filter plates 150 are squeezed to filter the material, and the material can be secondary filtered through the collecting box 210 and the filter plate 220, which can improve the filtering effect of the material. Secondly, the push plate 140 can be moved by the extension and contraction of the hydraulic cylinder 130, and the movement of the push plate 140 can move the multiple filter plates 150. When the filter plates 150 move, the arc plates 160 between the filter plates 150 move away from each other, and then the second support plate 172 will move and extend, so that the second support plate 172 is extended, so that there can be a gap between the filter plates 150, thereby reducing the number of times the staff separates the filter plates 150 before cleaning the filter plates 150, facilitating the secondary filtration of the solid materials in the filtered solution to prevent the waste of raw materials. At the same time, it is convenient to leave a certain gap between two adjacent filter plates 150, so as to facilitate the cleaning of the filter plates 150, thereby improving practicality.
