Problems solved by technology

For the ultrafiltration membrane without washing, the impurities gradually adhere to the micropores of the ultrafiltration membrane during the filtration process, and the filter pore size of the ultrafiltration is gradually blocked, and the service life is short
However, the ultrafiltration membrane silk that is being flushed cannot flush all the micropores on the surface of the ultrafiltration membrane, and only has a flushing effect on the ultrafiltration membrane with a large water flow near the flushing port. effect

Abstract

The invention relates to a filter element backwashing device which comprises a filter element. A water purifying and storing cavity is arranged inside the filter element. A filter bottle sleeves the filter element. A raw water storage cavity is arranged between the filter bottle and the filter element. A filter bottle cover is mounted at the top of the filter bottle. A raw water inlet, a purified water outlet and a washing water outlet are formed in the filter bottle cover. A rotary switching mechanism for switching the water purifying state and backwashing state of the filter element is mounted on the filter bottle cover. The filter element backwashing device has the advantages that the normal filtering state and the backwashing state of the filter element can be switched by the rotary switching mechanism mounted on the filter bottle cover, the problem that backwashing cannot be performed during the using process of the filter element, the service life of the filter element is prolonged by performing backwashing on the filter element, and cost is saved.

Description

technical field [0001] The invention relates to water purifier equipment, in particular to a filter element backwashing device. Background technique [0002] At present, filter elements, such as ultrafiltration membranes, are mostly not flushed or are flushed. For the ultrafiltration membrane without flushing, the impurities gradually adhere to the micropores of the ultrafiltration membrane filament during the filtration process, and the filtration aperture of the ultrafiltration membrane is gradually blocked, and the service life is short. However, the ultrafiltration membrane silk that is being flushed cannot flush all the micropores on the surface of the ultrafiltration membrane, and only has a flushing effect on the ultrafiltration membrane with a large water flow near the flushing port. effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a filter element backwashing device with obvious flushing effect ...
