Abstract

The invention discloses a reverse washing prefilter which comprises a filter element and a shell arranged outside the filter element. The shell comprises an upper shell and a lower shell which are hermetically and integrally connected, a water inlet and a water outlet are formed in the upper shell, a water inlet cavity is formed in the upper shell, the water inlet is communicated with the inside of the water inlet cavity, the water outlet is communicated with the inside of the filter element, the upper shell comprises an upper sealing part and a lower sealing part which are positioned on the upper portion and the lower portion of the water inlet cavity respectively, water through openings are formed in the upper sealing part and the lower sealing part, a conversion rod is inserted into the water inlet cavity, the upper portion of the conversion rod sequentially penetrates the water through opening of the upper sealing part and the top of the upper shell, a sealing gasket for hermetically matching with the water through openings is arranged at the conversion rod between the upper sealing part and the lower sealing part, and a drainage valve is arranged at the bottom of the lower shell. According to the reverse washing prefilter, reverse washing operations are simple, and the filter element does not need to be disassembled, washed or replaced by professional staff.

Description

technical field [0001] The invention relates to a reverse direction flushing pre-filter, which can be used to purify water in domestic pipelines and belongs to the technical field of water purification treatment. Background technique [0002] At present, in the sanitary ware water purification industry, during the use of coarse purified water pre-filter products, the filter element is prone to deposit dirt, causing secondary pollution to water quality, which requires disassembly, cleaning or replacement of the filter element. For the disassembly and cleaning of the filter element, it is time-consuming to disassemble and easily damage the filter element, and cleaning the filter element after disassembly is not only time-consuming and laborious, but also difficult to clean, and requires professional operation at the same time. Replacing the filter element increases the cost of using the filter element. Moreover, the existing pre-filter with the function of flushing in the rev...
