[0002] Aeration refers to the process of forcibly transferring oxygen from the air into the liquid in order to obtain sufficient dissolved oxygen. Aeration technology is often used in sewage treatment to provide sufficient oxygen for aerobic organisms in the sewage, enabling them to decompose and clean impurities such as organic matter in the sewage, thereby achieving the purpose of sewage treatment. Therefore, an aeration structure is needed.

One end of the rotating shaft 3 is connected to the output end of the stirring motor 14. One side of the sewage tank 1 is equipped with a control surface Plate 32; During operation, in actual application, the lack of multi-angle stirring reduces the contact opportunities between microorganisms in sewage and oxygen and pollutants, resulting in uneven distribution of oxygen in sewage, making it difficult to fully decompose organic pollutants, and resulting in low sewage treatment efficiency. The stirring motor 14 is started, and the output end of the stirring motor 14 drives the rotating shaft 3 to rotate. Since the driving wheel 11 and the driven wheel 12 are connected by the belt 13, the two rotating shafts 3 can rotate synchronously. When the rotating shaft 3 rotates, the spiral blade 4 at its bottom rotates accordingly. The spiral blade 4 stirs the sewage at the bottom of the sewage tank 1, causing the sewage at the bottom to have an upward flow trend. At the same time, the stirring blade 5 also begins to stir the sewage on the upper part of the sewage tank 1. The driving bevel gear 7 rotates with the rotating shaft 3. Since the driving bevel gear 7 and the driven bevel gear 9 are meshed with each other, the driving bevel gear 7 drives the driven bevel gear 9 to rotate, thereby driving the rotating shaft 8 to rotate, so that the stirring blade 10 starts to stir the sewage horizontally, realizing multi-angle stirring operation of the sewage inside the sewage tank 1, increasing the contact area between the sewage and the air, and improving the sewage treatment effect.

[0024] See also Figure 1 、 2 As shown in Figures 4 and 5, an air inlet pipe 15 is installed on one side of the sewage tank 1, one end of the air inlet pipe 15 is connected to a delivery pipe 16, the delivery pipe 16 is installed on the bottom inner wall of the sewage tank 1, and five connecting pipes 17 are installed at equal distances on both sides of the delivery pipe 16. An aerator 18 is installed on the outside of the connecting pipe 17;

[0025] An installation cavity 19 is installed on the outside of the air intake pipe 15, and a filter screen 20 is installed on the inner wall of the installation cavity 19.

A sewage pipe 28 and a drain pipe 29 are respectively installed at the bottom end and the middle end of the other side of the sewage pool 1. A sewage valve 30 and a drain valve 31 are respectively installed on the outside of the sewage pipe 28 and the drain pipe 29; when working, an aeration process is often used in sewage treatment to provide sufficient oxygen for aerobic organisms in sewage so that they can decompose and clean impurities such as organic matter in sewage, thereby achieving the purpose of sewage treatment. Therefore, an aeration structure is needed. The sewage to be treated is injected into the sewage pool 1 through the water inlet pipe 27, and one end of the water inlet pipe 27 extends to the bottom end of the sewage pool 1 to ensure that the sewage can fully enter the treatment area. The negative pressure motor 22 is started, and its output end drives the fan The blades 24 rotate, generating negative pressure, allowing air to enter the intake pipe 15. When air enters the intake pipe 15 from the outside, it is first filtered by the filter 20, effectively filtering out impurities in the outside air. The air is then transported to the connecting pipes 17 through the delivery pipes 16. The connecting pipes 17 then distribute the air to the aerators 18. Finally, the aerators 18 release the air into the sewage in the form of tiny bubbles, allowing the oxygen in the air to fully dissolve in the sewage, promoting the growth and reproduction of microorganisms and accelerating the decomposition of organic matter. When the connecting shaft 23 rotates, the scrubbing brush 25 rotates accordingly, cleaning the filter 20 to prevent impurities from clogging the filter 20. The cleaned impurities are discharged through the through-holes 26. The specific model of the aerator 18 is QS-PD-260.

[0028] Working principle: The sewage to be treated is injected into the sewage pool 1 through the water inlet pipe 27. One end of the water inlet pipe 27 extends to the bottom of the sewage pool 1 to ensure that the sewage can fully enter the treatment area. The negative pressure motor 22 is started, and its output end drives the fan blades 24 to rotate, generating negative pressure, so that air enters the air inlet pipe 15. When the air enters the air inlet pipe 15 from the outside, it is first filtered by the filter 20 to effectively filter out impurities in the outside air. Then the air is transported to the connecting pipe 17 through the conveying pipe 16, and then the connecting pipe 17 distributes the air to each aerator 18. Finally, the aerator 18 releases the air into the sewage in the form of tiny bubbles, so that the oxygen in the air can be fully dissolved in the sewage, promoting the growth and reproduction of microorganisms and accelerating the decomposition of organic matter. When the connecting shaft 23 rotates, the scrubbing brush 25 rotates accordingly to clean the filter 20 to prevent impurities from clogging the filter 20. The cleaned impurities are discharged through the through hole 26.

[0029] Start the stirring motor 14, and the output end of the stirring motor 14 drives the rotating shaft 3 to rotate. Since the driving wheel 11 and the driven wheel 12 are connected by the belt 13, the two rotating shafts 3 can rotate synchronously. When the rotating shaft 3 rotates, the spiral blade 4 at its bottom rotates accordingly. The spiral blade 4 stirs the sewage at the bottom of the sewage tank 1, causing the sewage at the bottom to have an upward flow trend. At the same time, the stirring blade 5 also starts to stir the sewage in the upper part of the sewage tank 1, and the driving bevel gear 7 rotates together with the rotating shaft 3. Since the driving bevel gear 7 and the driven bevel gear 9 are meshed with each other, the driving bevel gear 7 drives the driven bevel gear 9 to rotate, thereby driving the rotating shaft 8 to rotate, so that the stirring blade 10 starts to stir the sewage horizontally, realizing a multi-angle stirring operation of the sewage inside the sewage tank 1, increasing the contact area between the sewage and the air, and improving the sewage treatment effect;

[0030] The treated sewage can be discharged from the drain pipe 29 by opening the drain valve 31. The sediment and other impurities generated during the treatment process can be discharged from the drain pipe 28 by opening the drain valve 30, thereby achieving efficient treatment of the sewage.
