Lifting type automatic cleaning dissolved oxygen aeration device

The invention discloses a lifting type automatic cleaning dissolved oxygen aeration device. The device comprises an aerobic biochemical pool, a speed reducer power assembly, a steel wire rope winding drum installed on a rotating shaft of the speed reducer power assembly, a steel wire rope wound on the steel wire rope winding drum, a rubber nano aeration system frame mounted on the inner side of the aerobic biochemical pool, an extrusion roller assembly, a guide pulley block and at least one row of rubber nano aeration pipes. The lifting type automatic cleaning dissolved oxygen aeration device has the advantages that firstly, the traditional use method of the aeration pipes is changed, the pipe distribution density is increased, the occupied area of an aerobic biochemical pool is reduced, and the utilization efficiency of the pool capacity of the aerobic biochemical pool is improved; and secondly, an easy-to-scale material adhesion layer and an easy-to-crystallize material crystallization layer are effectively
