Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and more particularly to a high-efficiency aeration device for sewage treatment. Background Art

[0002] The aeration device is a sewage treatment device. During the sewage treatment process, the aeration device forces air into the sewage, allowing the sewage in the pool to come into contact with the air and be oxygenated, and stirs the liquid to accelerate the transfer of oxygen in the air to the liquid, preventing suspended objects in the pool from sinking, strengthening the contact between organic matter in the pool and microorganisms and dissolved oxygen, and oxidizing and decomposing organic matter in the sewage.

[0003] Based on the above, the inventors found that the existing aeration device mainly consists of an air pump and a nozzle, which is fixedly connected to the nozzle. The nozzle is then laid at the bottom of the sewage pool. The air pump is used to transport air to the nozzle to aerate the sewage. However, the nozzle is fixed in position, resulting in a fixed range of air transportation, which affects the aeration range and aeration efficiency. Therefore, in view of this, the inventors studied and improved the existing structure to provide a high-efficiency aeration device for sewage treatment, in order to achieve a more practical purpose.

Under the cooperation of the transmission belt 10 and the transmission ring 6, the multiple support shafts 5 rotate synchronously.

[0030] See Figure 1 The vertical positions of the two adjacent groups of air outlet pipes 9 are staggered, and the air supply pipe 3 and the air outlet pipe 9 are connected. Air is transported from the air inlet box 4 to the inside of the air supply pipe 3, and the air passes through the support shaft 5 and is discharged from the air outlet pipe 9, contacts with the sewage, and performs aeration work.

[0031] See Figure 2 The movable ring 8 is located inside the gas pipe 3 and is movably connected to the gas pipe 3 , and the movable ring 8 ensures the stability of the upper end of the support shaft 5.

[0032] See Figure 4 The lower support plate 11 is located below the support shaft 5 , and the lower support plate 11 is symmetrically arranged with the upper support frame 1 . The lower support plate 11 cooperates with the limiting sleeve 12 to limit the lower end of the support shaft 5 .

[0033] See Figure 4 The bottom end of the support shaft 5 is fixedly connected to the top surface of the movable seat 13, and the movable seat 13 is movably connected to the limiting sleeve 12. The support shaft 5 drives the outlet pipe 9 to rotate, which plays a role of rotary stirring, expands the aeration range, and improves the aeration efficiency.

At the same time, the drive motor 2 is started, and with the cooperation of the transmission belt 10 and the transmission ring 6, multiple support shafts 5 rotate synchronously. The support shaft 5 drives the air outlet pipe 9 to rotate, which plays a role of rotational stirring, expands the aeration range, and improves the aeration efficiency. At the same time, the support shaft 5 drives the movable seat 13 to rotate inside the limit sleeve 12. The movable seat 13 causes the ball 14 to rub against the inner surface of the limit sleeve 12. The ball 14 rubs, reducing the rotation resistance of the movable seat 13, thereby ensuring the rotation stability of the aeration component.
