[0002] In the chemical production process, filtering and treating chemical waste liquid is a key process, the main purpose of which is to achieve effective separation of solid and liquid wastes for subsequent transportation and centralized treatment. This treatment method is of great significance for environmental protection and resource recycling.

[0003] A Chinese patent with application number CN202020360821.7 discloses a chemical filtration device for chemical production. Although it solves the problem of impurity accumulation on the surface of the filter screen and reduces the filtering effect to a certain extent, the existing chemical filtration device can scrape impurities from the surface of the filter screen to one side, but the impurities on the filter screen are not thoroughly cleaned. This causes a large amount of impurities to gradually accumulate on the surface of the filter screen, thereby affecting the filtering efficiency. In order to ensure the smooth progress of the filtration process, the existing filtration device needs to frequently stop the filtration work in order to clean the filter screen. This process not only increases the complexity of the operation, but also leads to a decrease in production efficiency. In addition, frequent disassembly and cleaning work may also damage the filter screen and shorten its service life. Utility Model Content
