Description

Technical Field

[0001] The utility model relates to the technical field of sewage aeration, in particular to a sewage treatment aeration device. Background Art

[0002] The sewage treatment aeration device is an important sewage treatment equipment. It injects air into the water body to cause the organic matter in the sewage to react with oxygen to degrade the organic matter, thereby achieving the purpose of purifying the water quality. This device is usually composed of an aeration pipe, a gas supply system and a control system. The aeration pipe is the core component of the sewage treatment aeration device, and it is usually made of corrosion-resistant materials;

[0003] After searching, the utility model with the announcement number CN220283816 U discloses a sewage treatment aeration device. Although the utility model patent solves the problem that the surface of the bottom wall of the treatment tank becomes a dead corner of the aeration treatment, and siltation occurs at the bottom of the treatment tank;

[0004] First, the utility model only increases the contact area between airflow and sewage by opening various holes, and the air holes are small to increase the contact area between air and sewage, so the air holes are easily attached by silt. Once the silt deposited at the bottom blocks the air holes, the aeration efficiency will decrease rapidly. The utility model lacks the ability to clean the environment and has limitations;

[0005] Second, the utility model can only lift the bottom silt to improve the aeration efficiency, but lacks the function of lifting the sewage at a higher water level, resulting in low aeration efficiency. Moreover, the utility model can only lift the silt at a fixed position, but cannot fully stir the sewage pool, which easily causes uneven aeration effect.

[0006] Therefore, a sewage treatment aeration device is proposed. Utility Model Content

[0007] In view of this, the utility model provides a sewage treatment aeration device to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.

[0010] Further preferably, the number of the bristles is multiple, and the multiple bristles are evenly distributed on the surface of the propulsion screw. The multiple bristles are convenient for raising more fine bubbles, improving aeration efficiency, and can also clean the pores to prevent pore blockage.

[0011] Further preferably, the shape of the slider is "C"-shaped, and the "C"-shape of the slider is located outside the limiting frame.

[0012] Further preferably, there are multiple air holes, and the multiple air holes are evenly opened at the top and bottom of the air transfer pipe.

When the gear meshes with the lower part of the teeth, the support rod rotates and drives the bristles to rotate close to the air hole. During the rotation of the bristles, the air hole is cleaned to prevent the air hole from being attached to silt and affecting the aeration efficiency;

[0016] 2. When the gear of the utility model is meshed with the upper part of the teeth, close to the upper part of the sewage, the support rod rotates to drive the bristles to rotate, driving the sewage to the water surface, increasing the contact area between the sewage and the air, and improving the aeration efficiency.

An air pump 15 is fixedly connected to the upper surface of the support frame 2, the exhaust port of the air pump 15 is connected to an exhaust pipe 16, the bottom of the exhaust pipe 16 is connected to an air transfer pipe 17, the air transfer pipe 17 passes through the support frame 2 and is located in the sewage treatment tank 1, and the outer wall of the air transfer pipe 17 is provided with air holes 18.

[0027] In one embodiment, the number of bristles 14 is multiple, and the multiple bristles 14 are evenly distributed on the surface of the propulsion screw 13. The multiple bristles 14 are convenient for lifting more fine bubbles and improving the aeration efficiency. At the same time, the air holes 18 can be cleaned to prevent the air holes 18 from being blocked. The shape of the slider 7 is "C" shaped, and the "C" shape of the slider 7 is located outside the limit frame 5. The number of air holes 18 is multiple, and the multiple air holes 18 are evenly opened at the top and bottom of the air transfer tube 17. The air holes 18 located at the bottom of the air transfer tube 17 lift the sediment at the bottom of the sewage treatment tank 1, and the air holes 18 located at the top of the air transfer tube 17 generate bubbles upward to improve the aeration efficiency. The support frame 1 2 and the support frame 2 4 are parallel to each other. The number of support shells 9 is two, and the two support shells 9 are located on both sides of the motor 10. The two support shells 9 support the motor 10 more stably.

[0028] When the utility model is working: when it is necessary to aerate the sewage in the sewage treatment pool 1, the motor 10 and the air pump 15 are started, the air inlet of the air pump 15 sucks in air, and the exhaust hole 18 of the air pump 15 is connected to the exhaust pipe 16 and the air transfer pipe 17, so that the air is discharged into the exhaust pipe 16 and the air transfer pipe 17, and the exhaust pipe 16 and the air transfer pipe 17 are located in the sewage, and the outer wall of the air transfer pipe 17 is provided with an air hole 18, so that the air is discharged into the sewage through the air hole 18, thereby increasing the contact area between the sewage and the air; the motor 10 drives the gear 11 and the support rod 12 to rotate; when the gear 11 rotates, because the gear 11 is meshed with the teeth 6, and the teeth 6 are stationary, the gear 11 moves along the teeth 6, The lower gear 11 of the limit frame 5 moves around the teeth 6.
