Existing multi-media filters for water treatment are difficult to completely remove impurities after rinsing, requiring the filter screen to be disassembled to thoroughly clean large particles, which is inconvenient to use.
A multi-media water treatment filter was designed. The filter uses a motor-driven gear to drive a rotating drum and scraper, which, together with a sealing ring and a retaining ring, enables the intermittent discharge of impurities. The filter cartridge can be easily disassembled through a limiting component, improving cleaning efficiency and convenience.
This allows for the timely removal of impurities, improving the practicality and convenience of the filter and reducing its impact on the filtration process.
