Impurities are carried by the water flow through the cleaning brush 223 and the sealing ring 221 into the upper part of the cylinder 111 and discharged through the sewage outlet pipe 114. The setting of the fixing plate 122, the mounting plate 123, and the positioning ring 124 allows for convenient positioning and installation of the filter cartridge 121, facilitating disassembly and maintenance. The setting of the sealing ring 221 and the sealing disc 222 allows the electric cylinder 211 to drive the cleaning brush 223 to clean the filter cartridge 121 while facilitating the discharge of sewage from the sewage outlet pipe 114 without affecting the normal filtration of the water flow.

[0043] Example 2: In some embodiments, such as Figure 3 As shown, in a preferred embodiment of the present invention, a backwash pipe 3 is also fixedly installed on the side wall of the cylinder 111. A valve is provided at the end of the backwash pipe 3 and the clean water outlet pipe 113 away from the cylinder 111. The backwash pipe 3 is connected to the water supply equipment.

[0044] When the self-draining and cleaning filtration equipment is in normal use, the valve of the backwash pipe 3 is opened and the valve of the clean water outlet pipe 113 is closed at the same time the electric cylinder 211 is started. The water supply equipment delivers clean water to the outside of the filter cartridge 121. The clean water gradually increases inside the cartridge 111 and enters the inside from the outside of the filter cartridge 121, backwashing the impurities on the side wall of the filter cartridge 121 and improving the cleaning effect. The backwash pipe 3 is designed to improve the cleaning effect and prevent the cleaning brush 223 from pushing impurities into the filter holes of the filter cartridge 121 and causing blockage.
