Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

As Fig. 1, Fig. 2, the cleaning device of a kind of filter shown in Fig. 3, there is filter core 1, between the sidewall of filter core 1 and housing 5 and telophragma 2, be provided with gap, gap UNICOM composition filtrate chamber 13, the top of housing 5 is provided with filtrate (liquid 7, filtrate (liquid 7 and filtrate chamber 13 UNICOMs, filter core 1 is fixed on the telophragma 2 of filter, telophragma 2 is set on main shaft 3, main shaft 3 connecting drive devices 4, drive unit 4 is located at the top of filter housings 5, the bottom of housing 5 is provided with filtrate import 6, filtrate import 6 and filter core 1 UNICOM, the bottom that sewage draining exit 8 is located at housing 5 is connected with magnetic valve 9, in housing 5, be provided with differential pressure controller 10, the top of described filter core 1 is provided with cleaning brush 11, cleaning brush 11 is connected with support frame 12, support frame 12 is connected with the free termination of expansion link 14, between every support frame 12 and sliding sleeve 16, be provided with support bar 15, the two ends of support bar 15 are hinged with support frame 12 and sliding sleeve 16 respectively, sliding sleeve 16 is slidably located in outside expansion link 14, expansion link 14 is located at the top of filter core 1, the radius of cleaning brush 11 is not less than the radius of filter core 1, expansion link 14 is by main shaft 3 connecting drive devices 4, when expansion link 14, in the time extending, to promote sliding sleeve 16 close to support frame 12, simultaneously, the supported bar 15 of support frame 12 promotes and opens, the inwall that makes cleaning brush 11 can contact filter core 1 can clean the dirt of the inside that is attached to filter core 1, cleaning brush 11 is opened when in use, when use, can draw in, do not affect normal filtration, save time, laborsaving, operating efficiency is high again.
