[0024] Example:

[0025] As attached Figure 1 To the attached Figure 3 As shown:

[0026] The utility model provides an MBR membrane circulation cleaning device, comprising a water reservoir 1, a membrane box 2 and a hanger 3 are respectively provided on the water reservoir 1, the bottom of the membrane box 2 is open and communicated with the interior of the water reservoir 1, a cleaning component is slidably provided in the hanger 3, and the cleaning agent after cleaning the MBR membrane in the membrane box 2 falls into the water reservoir 1, a plurality of vertical MBR membranes are inserted in the membrane box 2, and the plurality of membranes are distributed in parallel. In other embodiments, the membrane box 2 is replaced by a positioning box, and the MBR membrane to be cleaned can be placed in the positioning box along with the box body and placed in the same position for cleaning;

[0027] The top of the cleaning component is connected to a lifting mechanism, including a swivel seat arranged on the top of the hanger 3, which is rotatably connected to a hanging wheel 4. The hanging wheel 4 is driven by a motor, and a cable 5 is wound around the hanging wheel 4. Both ends of the cable 5 are respectively led out from the hanging wheel 4 and connected to the cleaning component. The cleaning component can be lifted or lowered by rotating the hanging wheel 4.

[0028] The cleaning assembly includes a cleaning rack 6. The top of the hanger 3 is provided with guide blocks on both sides of the hanging wheel 4. The guide blocks are rotatably connected to the guide wheel 10. The cable 5 is connected to the cleaning rack 6 through the guide wheel 10. The guide wheel 10 increases the stability of the cable 5. The hanging wheel 4 can drive the cleaning rack 6 to rise and fall. A plurality of flushing plates 11 are distributed in an array at the bottom of the cleaning rack 6.
