In a preferred embodiment of the present invention, the coupling 2 is a cross-bearing universal joint.

As a preferable mode of this embodiment, the stirring device further includes a shaft sleeve 9, and the shaft sleeve 9 is sleeved on the stirring shaft 6.

As a preferable mode of this embodiment, a lower bearing housing 8 is connected to one end of the housing 5, and a lower bearing 10 is fixed to the lower bearing housing 8.

In a preferred embodiment of the present invention, the stirring shaft further comprises a first washer 7 and a second washer 11, and the shaft sleeve 9 is locked on the stirring shaft 6 through the first washer 7, the second washer 11, the stirring propeller 12 and the self-priming propeller 13.

As a preferable mode of the present embodiment, the motor 1 is a dry outdoor type motor.

The utility model discloses the theory of operation: the stirring propeller 12 of the high-efficiency self-suction plug-flow aeration stirrer is placed at a position which is larger than or equal to 300mm underwater, and the shaft of the motor 1 drives the stirring propeller 12 and the self-suction propeller 13 to rotate at 730 rpm. Negative pressure is formed in a water area near the self-suction propeller 13, and a large amount of air is injected at high speed through the air inlet 4-1, the air inlet chamber 4, the outer cover 5, the stirring shaft (hollow shaft) 6 and the self-suction propeller 13. The sucked air is atomized and broken into numerous fine air bubbles by the self-suction air atomizer 14, and then is sufficiently mixed with water. The stirring propeller 12 propels the fine bubbles wrapped on the water surface to the bottom of the pool along with the water flow, so that the bubbles are diffused to a farther and wider water area, and the fine bubbles are slowly released from the pool bottom to the water surface, thereby increasing the oxygenation process and time and greatly improving the oxygenation efficiency.

The contact time of the bubbles and the water is long, and the contact surface area is large. The bubbles can be fully mixed with sewage at the bottom of the pool, the moving distance of the bubbles in water is long, the diffusion speed of the bubbles in water is high, the bubbles are released from the water bottom, the probability that the bubbles collide with each other and merge in water is low, the sewage oxygenation efficiency is greatly improved, and the service area is increased.

The bubbles are atomized, crushed, cut and stirred by the self-suction propeller and the stirring propeller and then mixed with the sewage. The air bubbles are smaller than those of a surface aerator, a jet aerator and a centrifugal aerator, and the high-efficiency self-suction plug flow aeration mixer does not need to be provided with an air blower for self-suction, thereby reducing the equipment operation cost. After being fully mixed with water, the bubbles are quickly pushed forward by the stirring propeller to a far distance and spread. The oxygen-filling supersaturation and bubble collision combination probability near the self-suction propeller can be greatly reduced. Because the water body is propelled forwards in a spiral line mode under the action of the stirring propeller, the small bubbles are spirally turned up and down along with the water flow in the forward moving and slow rising processes, the motion track is lengthened, and the contact time with water and the stroke in the water are greatly prolonged. Therefore, the device has higher dissolved oxygen efficiency than a pipeline microporous aerator (bubble rises straight), a jet aerator (inclined rise), a centrifugal aerator (horizontal spiral rise), a rotary disk aerator and other surface aerator (surface peripheral horizontal diffusion and almost no oxygenation capacity at the bottom of the tank).

The machine can automatically control the running time period by the control cabinet according to different process requirements so as to obtain the best sewage treatment process effect and the lowest energy consumption.
