[0002] In the production of chemical auxiliaries, the reaction of raw materials produces harmful substances such as impurities and unreacted particles. These impurities need to be removed by filtration equipment to ensure the purity of the chemical auxiliaries. Existing chemical auxiliary filtration equipment mostly adopts a single filter layer structure, which has low filtration accuracy and cannot meet the requirements of high-precision filtration. At the same time, impurities easily adhere to the surface of the filter element during filtration, causing a rapid decline in filtration efficiency. Furthermore, the filter element is inconvenient to clean and requires frequent disassembly and replacement, increasing production costs and downtime. Therefore, there is a need to propose a new type of filtration equipment for the production of chemical auxiliaries. Utility Model Content

On the right side of the filter plate 6 on the left side of each set of filter plates 6, a set of slots 10 is provided. Each slot 10 has a baffle 11 inside, which is fixedly installed inside the slot 10. Each set of filter plates 6 has a set of movable grooves 1 on the left side of the right-side filter plate 6.

The rotation of brush plate 19 can scrape off the particles filtered on the top surface of filter plate 6, preventing long-term adhesion and reducing filtration rate.

[0018] In this embodiment, when using this device, the chemical additive to be filtered is first injected into the filter cylinder 1 through the feed inlet 20. Then, the motor 3 is run, and the output end of the motor 3 drives the rotating rod 4 to rotate. The rotation of the rotating rod 4 drives the brush plate 19 to rotate. The rotation of the brush plate 19 can continuously scrape and clean the top surface of the filter plate 6, thus preventing particles from adhering for a long time and reducing the filtration rate. When filtration is complete and the filter plate 6 needs to be disassembled, the cylinder cover 2 is moved away from the top of the filter cylinder 1, and then the toggle block 16 can be moved in two opposite directions. The movement of the toggle block 16 can drive the connecting block 15 and the slider 14 to move away from each other, thereby... Move connecting block 17 and locking block 18 from the position of the baffle 11 to the other side, so that locking block 18 can be pulled out from the inside of the slot 10, thereby completing the disassembly of the filter plate 6. When installation is required, align the annular groove on each set of filter plates 6 with the annular bar 27, and move the lever 16 so that the locking block 18 is aligned with the position in the slot 10 without the baffle 11 for installation, thereby installing the locking block 18 into the inside of the slot 10. Then release the limit on the lever 16, so that the slider 14 is pushed back to its original position by the spring 13, so that the locking block 18 moves to the position in the slot 10 with the baffle 11 as the limit. Then align the trapezoidal bar 28 on each set of filter plates 6 with the trapezoidal groove and install it into the inside of the filter cylinder 1.
