[0002] In the production process of insecticide, raw materials and reaction mixture often contain various impurities, such as solid particles, unsolved substances, impurity ions, etc. If these impurities are not effectively removed, they will have serious negative effects on the quality, stability, efficacy and safety of insecticide. For example, impurities may cause the insecticide to precipitate and stratify during storage, affecting its uniformity and use effect; during pesticide application, impurities may clog the spray head, making the spray uneven and reducing the control effect on pests; even some impurities may react with active ingredients, reducing the content of active ingredients and shortening the shelf life of insecticide. Therefore, filtration treatment is often required during the production of insecticide.

After long-term use, impurities will gradually accumulate on the surface of the filter elements, causing increased filtration resistance and reduced filtration efficiency. At this time, the filter elements need to be cleaned or replaced. However, the structure design of traditional devices makes this operation extremely inconvenient. The filter elements of some devices are installed in a closed and narrow space, and the disassembly process is complex, requiring a lot of time and labor, which seriously affects production efficiency. In addition, the traditional filter and impurity removal device needs to be adjusted and reassembled when cleaning, and cannot clean the inside of the device itself during use, thereby increasing the work intensity and reducing the production efficiency. Therefore, it is an urgent technical problem to develop a filter and impurity removal device that can easily replace and clean the filter elements and easily clean the inside of the device.
