Of course, the up-down driving device 3 or the left-right driving device 4 may be independently turned on according to actual needs.

Since the cleaning module 1 (or the flushing pipe 11) can move up and down, left and right, the MBR membrane automatic cleaning device can clean membrane modules 100 with different sizes.

Wherein, the left and right stroke of the supporting plate 22 can be changed by adjusting the connecting position of the left and right turntables 42 and the left and right driving rods 43 (namely, changing the distance between one end of the left and right driving rods 43 and the axle center), thereby changing the left and right movement stroke of the cleaning assembly 1; similarly, the up-down movement stroke of the cleaning assembly 1 can be changed by adjusting the connection position of the up-down turntable 32 and the up-down driving rod 33.

According to the length of the MBR membrane 101, the number of the layers (namely the number of the tube frames 12) of the corresponding flushing tubes 11 can be selected and assembled, so that the flushing tubes 11 are prevented from colliding with the membrane frame 102 when the cleaning assembly 1 moves up and down. Generally speaking, the distance between two adjacent pipe frames 12 should not be greater than the stroke of the washing assembly 1 moving up and down, and the distance between two adjacent output holes on the washing pipe 11 should not be greater than the stroke of the washing assembly 1 moving left and right. Through the reasonable upper and lower, left and right stroke that sets up washing subassembly, make it and the number of piles of flushing pipe 11 and the distance phase-match between the delivery outlet to let above-mentioned MBR membrane self-cleaning equipment be applicable to not unidimensional MBR membrane and wash under the prerequisite of safe operation, realize the effect that the at utmost does not have the dead angle and wash the membrane silk.
