The staff will then use fasteners to penetrate the installation hole 16 to fix the bottom plate 15 to prevent the filter box 1 from shaking and affecting stability during operation. Subsequently, the passage of water through the water inlet pipe 2 is controlled by the water valve 3. After the water enters the filter box 1, it is filtered and impurities are removed through the multi-layer filter screen 10 on the inner side of the support plate 9. The filter screen 10 is firmly fixed on the inner side of the filter box 1 by the support plate 9, is not easily deformed by the impact of water flow, and has a better filtering effect.

The stirring rod 13 drives the water in the filter box 1 to shake, and the filter screen 10 is reversely flushed, so that some impurities attached to the filter screen 10 are flushed to one end of the water inlet pipe 2. Then, the sealing plate 6 and the support plate 9 are removed by removing the fasteners on the fixing block 7, so as to prevent impurities from passing through the filter screen 10 during cleaning and maintenance. After cleaning, the sealing plate 6 is continued to be installed on the inner side of the slot 5 through the sealing ring 8 to provide a filtering function.
