The flocculation tank in the drinking water treatment field mainly has grid flocculation and folded plate flocculation, wherein the grid flocculation tank is widely applied to various large and medium water plants in China due to the advantages of convenient installation, simple structure and the like. The grid flocculation tank is composed of a plurality of grid shafts, a plurality of layers of grid plates are arranged in each grid shaft and are staggered up and down to form a serial channel, and the grids form a speed gradient when passing water to start flocculation. Along with the time lapse, flocculation mud will progressively subside the adhesion on grid plate surface, and the mesh progressively dwindles or even blocks up, and the via hole velocity of flow increases, and velocity gradient changes to cause the unable gathering of tiny alum blossom, big alum blossom fracture, the flocculation effect variation, and then the condition of influence treatment water quality. When taking place above-mentioned condition, just need wash the maintenance to the grid plate, at present, the net of most water works all is independent installation, is fixed in the shaft, and during manual cleaning, at first need carry out the shut down to the production line, with flocculation basin emptying, adopt high-pressure squirt or artifical entering shaft in wash, the production influence is big, and the manual operation degree of difficulty is big. According to many cases in recent years, the problem that the grid plate of the flocculation tank is difficult to clean and maintain exists in a large quantity. Because urban water supply is in the nature, a water plant generally has no need of stopping production or reducing production, so that a grid plate which is not required to be taken out for cleaning and is convenient to clean must be developed, the normal operation of the water plant is guaranteed, the manual investment is reduced, and the quality of outlet water is ensured to reach the standard stably for a long time.
