[0002] During the sewage treatment process, certain methods and equipment are used to force air into the sewage, so that the sewage in the pool comes into contact with the air and is oxygenated, and the liquid is stirred to accelerate the transfer of oxygen in the air to the liquid, preventing suspended objects in the pool from sinking, and strengthening the contact between organic matter in the pool and microorganisms and dissolved oxygen, thereby oxidizing and decomposing the organic matter in the sewage. This process of forcing oxygen into the sewage is called aeration.

Once the micropores on the aeration pipes are clogged, the sewage in the sewage pool needs to be drained before the aeration pipes can be disassembled and repaired. Therefore, the utility model proposes an aeration device for sewage treatment. Utility Model Content

A second transmission assembly 6 is provided inside the horizontal pipe 3, and a first transmission assembly 7 is provided inside the vertical pipe 2. A driving motor 8 and an air pump 9 are installed on the upper surface of the support plate 1.

[0023] The first transmission assembly 7 includes a driving shaft 71 that passes through the top wall of the vertical tube 2 and is sealed and rotatably connected to the vertical tube 2. A first bevel gear 72 is fixed to the bottom surface of the driving shaft 71, and the first bevel gear 72 is located inside the bottom box 4. A square clamping block 73 is fixed to the top of the driving shaft 71, and a square clamping sleeve 81 is fixed to the bottom output shaft of the driving motor 8, and the clamping block 73 is clamped inside the clamping sleeve 81.

[0024] Torque can be transmitted through the clamping block 73 and the clamping sleeve 81 , so the driving motor 8 can drive the driving shaft 71 to rotate inside the vertical pipe 2 .

[0025] The second transmission assembly 6 includes a transverse shaft 61 rotatably connected to the inner wall of the transverse tube 3 , a second bevel gear 63 is fixed to one end of the transverse shaft 61 located in the bottom box 4 , and the second bevel gear 63 is meshed with the first bevel gear 72 , and a third bevel gear 62 is fixed to the surface of the transverse shaft 61 and near each cutting assembly 5 .

[0026] Under the transmission action of the second bevel gear 63 and the first bevel gear 72 , the driving shaft 71 can drive the horizontal shaft 61 to rotate.

[0027] The cutting assembly 5 includes a vertical shaft 51 that passes through the top wall of the horizontal tube 3 and is sealed and rotatably connected to the horizontal tube 3. The top of the vertical shaft 51 is fixedly connected to a blade 52, and the bottom of the vertical shaft 51 is fixedly connected to a fourth bevel gear 53, which is meshed with the corresponding third bevel gear 62.

[0028] Under the transmission action of the third bevel gear 62 and the fourth bevel gear 53, the horizontal shaft 61 can drive the vertical shaft 51 to rotate, and finally realize the rotation of the blade 52 at the top of the vertical shaft 51. Therefore, when the drive motor 8 is started, the drive motor 8 can drive the blade 52 of each cutting assembly 5 to rotate, and the rotating blade 52 can break up the bubbles discharged from the aeration hole 31 into tiny bubbles, thereby increasing the contact area between the bubbles and the sewage.

The slider 103 then drives the support plate 1 to move back and forth, and finally realizes the back and forth movement of the vertical pipe 2 and the horizontal pipe 3, so that the aeration range of the horizontal pipe 3 in the sewage pool is larger, which can reduce the number of aeration pipes installed at the bottom of the sewage pool.

[0033] Working principle: When installing the aeration device, fix the guide rail 101 to the top of the side of the sewage pool, and then place the horizontal pipe 3 inside the sewage pool. During aeration, start the air pump 9 and the drive motor 8. The air pump 9 can inject air into the vertical pipe 2 and the horizontal pipe 3, and the air is discharged from the aeration hole 31. The drive motor 8 drives the blades 52 of the multiple cutting components 5 to rotate rapidly at the top of the aeration hole 31, and uses the blades 52 to break up the bubbles discharged from the aeration hole 31 into tiny bubbles. At the same time, the servo motor 104 drives the support plate 1, the vertical pipe 2 and the horizontal pipe 3 to move back and forth, thereby increasing the aeration range of the horizontal pipe 3 at the bottom of the sewage pool.
