[0001] The present invention relates to the technical field of sewage treatment equipment, and particularly relates to an aeration device for treating aerobic granular sludge. Background Art

It belongs to a revolutionary technology in the aerobic biological treatment aspect of the sewage treatment field, and can completely replace traditional aerobic treatment processes such as the flocculent activated sludge method, and has significant significance for solving the problems of capacity expansion, quality improvement and efficiency increase faced by current sewage treatment plants.

[0003] However, for the current traditional aeration devices, the aeration intensity of the devices is not easy to regulate, and it is difficult to meet the requirements of different water quality aeration intensities. Since there are dead corners in the aeration range of the devices, and the volume of the dead corner area in the whole sewage treatment is large, it affects the efficiency of sewage treatment. Summary of the Invention

By rotating the rotating arm to drive the cylinder to rotate, and cooperating with the forward and backward swing conversion of the rotating frame, the cylinder can swing freely at an inclination of 60°, providing a dead-corner-free aeration effect; a centrifugal impeller is installed at a position corresponding to the mixing seat on the rotating rod. Through the rotation of the centrifugal impeller, the air flow of the mixing seat can be quickly discharged through the air duct, effectively ensuring the diffusion range of the air flow; since the piston plate reciprocates up and down along the sealing slide rail of the cylinder, the air flow of the mixing seat is pressurized by the piston plate, further increasing the aeration intensity.

[0015] Beneficial Effects

The rotation of the rotating arm drives the cylinder body to rotate, and cooperates with the forward and backward swing conversion of the rotating frame to achieve a 60° free swing of the cylinder body, providing an aeration effect without dead angles, thereby increasing the coverage volume of the sewage treatment aeration area.

[0017] In addition, a centrifugal impeller is installed at a position corresponding to the rotating rod and the mixed flow seat.

[0018] In addition, the rotating rod slides through the middle position of the piston plate, and the piston plate is slidably connected to the guide groove of the rotating rod through the convex shaft. During the rotation of the rotating rod, the piston plate reciprocates up and down along the sealing slide rail of the cylinder, and the airflow of the mixed flow seat is pressurized through the piston plate, thereby further improving the aeration intensity, thereby achieving the aeration intensity requirements of different water qualities.
