The fully automatic backwash filter overcomes many shortcomings of traditional filtering products such as small pollution capacity, easy clogging by dirt, the filter part needs to be disassembled and cleaned, and the filter status cannot be monitored. It has the function of filtering raw water and automatically cleaning and draining the filter element. The system provides uninterrupted water supply during cleaning and drainage, and can monitor the working status of the filter. It has a high degree of automation, covering various filtering accuracy requirements from 10um to 3000um, and providing customers with various water filtration equipment.

[0003] When the fully automatic backwash filter is in use, since the filter cartridge inside the fully automatic backwash filter is fixed, it is difficult to select different filtration accuracies according to different water demand, which reduces the application scope of the backwash filter. The higher the accuracy of the backwash filter, the cleaner the water quality, but it will increase the wear and tear of the filter. The existing backwash filter is not convenient for adjusting the filtration accuracy according to different actual usage conditions, and it is difficult to make the backwash filter reach a better use state. It has low intelligence and flexibility. Summary of the invention
