[0040] like Figure 1 and 2 As shown, sewage enters the aeration tank 1 through the water inlet pipe 3. Since the sewage needs to stay in the aeration tank 1, valves 4 are provided on the water inlet pipe 3 and the drain pipe 16 to control the discharge of the sewage.

[0041] The working process of the present invention is as follows: when the present invention is in use, sewage is discharged into the aeration tank 1, the air outlet of the air pump and the pipe interface of the first air guide reinforcement pipe 22 are sealed and rotated, the air outlet of the air pump injects gas into the first air guide reinforcement pipe 22, and at the same time, the motor 2 works, and the output end of the motor 2 drives the first pulley 15 to rotate. Since the first pulley 15 and the second pulley 13 are provided with a transmission belt 14, the first pulley 15 drives the second pulley 13 through the transmission belt 14, and the second pulley 13 drives the third rotating rod 26 to rotate, and the third rotating rod 26 drives the active bevel gear 31 to rotate, and the active bevel gear 31 drives the intermediate bevel gear 32 to rotate, and the intermediate bevel gear 32 drives the first air guide reinforcement pipe 22 to rotate, and the first air guide reinforcement pipe 22 drives the fixed blocks at both ends. The fixed block 40 drives the fixed inner ring 18 to rotate around the first air guide reinforcement tube 22 as the axis through the second air guide reinforcement tube 30, the fixed inner ring 18 drives the rotating outer ring 17 to rotate around the first air guide reinforcement tube 22, and the rotating outer ring 17 drives the outlet valve 38 to rotate around the first air guide reinforcement tube 22 as the axis, and the gas in the first air guide reinforcement tube 22 is injected into the fixed inner ring 18 through the second air guide reinforcement tube 30, and then enters the rotating outer ring 17 from the fixed inner ring 18, and the gas in the rotating outer ring 17 enters the outlet valve 38 through the telescopic tube 37, and the outlet valve 38 sprays the gas to contact the sewage to degrade the organic pollutants in the sewage. At the same time, the fixed inner ring 18 drives the rotating outer ring 17 to rotate around the first air guide reinforcement tube 22 as the axis. The movable bevel gear 39 rotates, and the fixed cylinder 28 fixes the position of the fixed bevel gear 29, and the rotating bevel gear 39 and the fixed bevel gear 29 are meshed. Therefore, the rotating bevel gear 39 meshes with the fixed bevel gear 29 during the circular rotation, thereby driving the rotating bevel gear 39 to rotate in a circular manner while rotating on its own. When the rotating bevel gear 39 rotates on its own, it drives the fourth rotating rod 50 to rotate. The fourth rotating rod 50 drives the rotating outer ring 17 to rotate on its own through the support frame 19. The rotating outer ring 17 drives the air outlet valve 38 to rotate on its own, thereby realizing the simultaneous cross-circular rotation of the two directions of the air outlet valve 38. The multi-directional rotation of the air outlet valve 38 is used to discharge air, and cyclonic flows in different directions are generated in the sewage.

The latch 35 on the collar 34 meshes with the closed arc groove of the cam 51 during the circular rotation of the collar 34, thereby driving the collar 34 to rotate and reciprocate along the axial direction of the cam 51. The collar 34 drives the struts 36 to swing synchronously during the reciprocating motion. The struts 36 drive the outlet valve 38 to swing slightly to adjust the outlet direction. The multi-directional rotation of the outlet valve 38 can generate cyclonic flows in different directions in the sewage, which can increase the contact area between the bubbles ejected from the outlet valve 38 and the sewage, and improve the degradation effect of organic pollutants in the sewage. When the outer ring 17 rotates in a circle parallel to the bottom surface of the aeration tank 1,The outlet valve 38 is directly opposite to the bottom of the aeration tank 1. The gas discharged from the outlet valve 38 can be used to blow up the organic pollutants precipitated at the bottom of the aeration tank 1 for secondary degradation, thereby improving the cleaning effect of the sewage. The cyclonic flow in different directions in the sewage can improve the degradation effect.

[0042] The intermediate bevel gear 32 drives the driven bevel gear 33 to rotate, the driven bevel gear 33 drives the second rotating rod 27 to rotate, the second rotating rod 27 drives the elliptical gear 6 to rotate, and the elliptical gear 6 drives the meshing gears 7 at both ends to rotate during the rotation, and the meshing gear 7 will be squeezed by the elliptical gear 6 during the self-rotation, which causes the sliding support plate 8 equipped with the meshing gear 7 to slide back and forth along the inner wall of the fixed plate 9 under the action of the sliding pin 10. The sliding support plate 8 drives the sliding rod 41 at one end to slide during the reciprocating sliding process. The spring 42 sleeved on the sliding rod 41 can be used to reset the sliding support plate 8, so that the meshing gear 7 always tends to the elliptical gear 6 to ensure the normal meshing of the two. The meshing gear 7 can bring The first rotating rod 23 is driven to slide toward one end, and the first rotating rod 23 drives the rotating lever 24 at the lower end to transport the floating foam to one end. When the sliding pin 10 slides back and forth with the sliding support plate 8, it drives the fixed shaft block 43 to move synchronously. The fixed shaft block 43 drives the air pressure rod 44 to reciprocate, and the air pressure rod 44 drives the air pressure plate 48 to slide back and forth in the air pressure cylinder 49, so as to generate negative pressure in the air pressure cylinder 49. The negative pressure in the air pressure cylinder 49 is transmitted to the pressure extraction pipe 45. After the floating foam is extracted by the pressure extraction pipe 45, it enters the air pressure cylinder 49 through the liquid inlet one-way valve 46, and then is transmitted to the pressure discharge pipe 11 by the liquid outlet one-way valve 47 in the air pressure cylinder 49, and is discharged to the storage box 5 by the pressure discharge pipe 11. The floating foam is collected by the storage box 5, which is simple and convenient.
