Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a circulation filter for repairing polluted groundwater. Background Art

[0002] When repairing groundwater, the groundwater is pumped up with a water pump and then filtered and purified. The filtered and purified water is then sent back underground. The filtration of groundwater requires the use of a filter.

[0003] The Chinese patent with announcement number CN217745996U discloses a circulating filter for repairing contaminated groundwater, comprising a filter cartridge, a partition and a filter screen, wherein a cleaning cartridge is coaxially sleeved on the outer side of each of the filter screens, a backflow hood is slidably connected to the upper side of the upper partition, and the backflow hood and the inner side of the cleaning cartridge are matched, and a water outlet hood is slidably connected to the lower side of the lower partition, a backflow water pipe connected to the inner side of the backflow hood is fixedly connected, and the backflow water pipe is connected to an external pressurized water delivery mechanism. In this scheme, a cylindrical cleaning cartridge is arranged on the outer side of the filter screen of the filter cartridge, and nozzles are arranged in an annular array on the inner wall of the cleaning cartridge, and a backflow hood and a water outlet hood are respectively arranged on the upper and lower sides of the inner side of the filter cartridge, the backflow hood conveys the clean water after external pressurization to the cleaning cartridge, and sprays it onto the filter screen through the nozzle, and compared with the reverse flow water flow at normal pressure, the impurities adhering to the filter screen can be more effectively removed, thereby improving the cleaning effect.
