Technical Field

[0001] The utility model belongs to the technical field of filter boxes, and in particular relates to an upper coarse separation screen device for an ornamental water filter box. Background Art

[0002] The mesh screen of the water filter box plays a vital role in the water treatment process. It mainly removes impurities and suspended matter in the water by physical filtration. Through the resistance of the mesh screen, suspended matter and impurities in the water are trapped on the surface of the mesh to prevent excessive impurities from entering the subsequent treatment links. As the first line of defense of the water treatment system, the mesh screen can effectively reduce the burden of subsequent treatment equipment and extend its maintenance cycle. In addition, through the filtering effect of the mesh screen, the water quality can be significantly improved to meet the water quality needs of different fields.

[0003] The mesh of the water filter box in the prior art needs to be frequently cleaned after a large area of ​​the mesh is clogged. Since the surface area of ​​the mesh is small, the cleaning frequency is high, which makes it inconvenient to use. In addition, the water body is in contact with the air for a short time during the filtration process, and the oxygen content of the water body is low. In addition, in the prior art, a germicidal lamp is generally used to sterilize the water body during the water filtration treatment stage. However, due to the fast flow rate of the water body, the residence time within the effective sterilization range of the germicidal lamp is short, so the sterilization effect is poor. In addition, the germicidal lamp is in contact with the water body for a long time, and the scale attached to the surface will seriously affect the sterilization effect. Utility Model Content
