improved flap filter
the flap filter is named after the filter backwash drain tongue valve (board) is flipped back and forth within the range of 0-90" in the working process. shenzhen qingquan water industry co., ltd. in 2004 (the first in china) will turn the plate filter. the pool technology was successfully introduced into shunde, guangdong, and innovatively developed a flip filter with sweeping function (having 1 utility model patent and 1 process control computer software 飞禽走兽游戏机 copyright), with rich engineering experience and equipment system integration capabilities.

shenzhen qingquan water made several improvements to the traditional flap filter:
1. innovatively developed a flip filter with sweeping function to solve the problem that surface foam is difficult to eliminate when backwashing;
2. developed and applied a multi-functional filter cloth cloth water and air distribution system with medium resistance water distribution and large resistance air distribution, making the filter cleaning water cloth more uniform;
the original design of the flushing intensity is optimized and reduced, saving equipment investment and water consumption.
