[0002] The rotary aeration propulsion jet integrated device is an environmentally friendly equipment used for sewage treatment. It combines the two functions of aeration and flow propulsion. The device promotes horizontal diffusion of water flow by aerating and stirring in the aeration area, so that the water in the aeration area circulates evenly and generates a strong axial thrust to push the water in the aeration area to flow to the oxygen-rich area at the bottom of the pool. At the same time, the aeration liquid curtain flows with the water to form a large convection cycle, thereby facilitating the treatment of sewage in the treatment tank.

The water tank 5 and the aerator 6 are connected to the connecting hose 7 through a connecting pipe. The threaded rod 10 is rotated by a driving mechanism 8. At this time, the threaded rod 10 will drive the movable plate 11 to move at a uniform speed along the guide rod 9, and then the stirring blades 17 can reciprocate between the inside of the tank body 1, cooperate with the aerator 6, and use mechanical stirring to increase the contact area between water and air, so that air can be evenly distributed into the tank body 1, which can effectively achieve the mixing of oxygen and activated sludge and improve the efficiency of sewage treatment.

The transmission wheels 18 are fixedly installed on the rotating shafts 16 on the same side. Scrapers 12 are fixedly installed on both sides of the movable plate 11. By controlling the stepper motor 13, the stepper motor 13 can use the driving wheel 20 to cooperate with the synchronous belt 19 to drive the transmission wheel 18 to rotate, so that the stirring blades 17 can rotate at a uniform speed in the tank body 1, and the staff can install a protective cover shell on the surface of the stepper motor 13 to prevent the stepper motor 13 from not working properly in the tank body 1.

[0024] An input pipe 4 is fixedly installed on the top of the tank body 1, an output pipe 2 is fixedly installed on the lower part of the outer periphery of the tank body 1, and a guide rod 9 is symmetrically fixedly installed in the middle part of the tank body 1. A movable plate 11 is slidably installed on the outer periphery of the guide rod 9. By setting the guide rod 9, the movable plate 11 can be limited to prevent the movable plate 11 from rotating during the movement, causing the connecting hose 7 to be intertwined and tangled, affecting the normal operation of the aerator 6, and a solenoid valve 14 is provided on the outer periphery of the connecting pipe. The rotating shaft 16 and the stirring blades 17 are both hollow and the surface of the stirring blades 17 is provided with evenly distributed slots.
