[0002] In water treatment technology, the filter tank is the most important water purification structure. Filtration, as a key process in water plants and sewage treatment plants, plays a final role in the treatment effect of the entire system. Its operating conditions directly affect the quality of the water produced by the water plant. The function of the filter tank is to remove particulate impurities in the water through the filtration and adsorption of filter materials such as quartz sand, anthracite or activated carbon.

[0003] The existing CN211435225U patent document proposes an integrated headless filter plate for gas-water backwashing, comprising an upper filter plate and a lower filter plate welded in a pool body, and the upper filter plate is located on the upper side of the lower filter plate, and the upper end of the upper filter plate and the lower end of the lower filter plate are respectively provided with a filter seam channel and a plurality of water distribution channels formed by laser cutting for medium entry and exit, the water distribution channel runs through the bottom end of the lower filter plate and is fixed to the lower filter plate, and a cavity is formed between the upper filter plate, the lower filter plate and the pool body, which can avoid the trouble of replacing the filter head in the subsequent water treatment process. At the same time, compared with the prior art, it has a long service life, reduces the flushing dead zone, and flushes the filter material more evenly. At the same time, it makes the installation of the filter plate faster, and reduces the trouble of cleaning the filter head and the filter cap of the filter head. Damage to the filter cap causes leakage of filter material, which affects the turbidity of filtered water not meeting the standard and the normal water supply during maintenance.

[0004] However, in order to clean the filter plate in time during use, the staff of the prior art patent technology with publication number CN211435225U needs to frequently observe the clogging condition of the filter plate, which is troublesome and reduces work efficiency. Utility Model Content
