AI Technical Summary
During the cleaning and lifting process, debris trapped by traditional flat plate filters can easily re-enter the water flow, making it difficult to remove effectively and affecting the normal operation of the circulating water system.
It adopts a layered filter screen structure, including filter frame one and filter frame two. Filter frame one uses a combination of filter screen and anti-escape filter screen, while filter frame two uses a flat filter screen. The filter frames are raised and lowered stably through a lifting mechanism, which facilitates installation, disassembly and cleaning.
It effectively intercepts dirt of different sizes, prevents impurities from escaping, ensures the continuous and efficient operation of the circulating water system, and extends the service life of the equipment.
