[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0032] Referring to Figure 1 , Figure 3 and Figure 4 , an embodiment provided by the present utility model: a sewage treatment aeration tank with an enhanced aeration function, including a tank body 1. On both the left and right sides of the outside of the tank body 1, a first motor 3 is fixedly connected. The output end of the first motor 3 is fixedly connected with an eccentric wheel 14. A connecting plate 15 is rotatably connected to the eccentric shaft pin of the eccentric wheel 14. One end of the connecting plate 15 is rotatably connected to an aeration plate 18. A plurality of aeration heads 19 are fixedly connected to the outside of the aeration plate 18. On both the left and right sides of the outside of the tank body 1, a blower 4 is fixedly connected. The output end of the blower 4 is fixedly connected with a transport pipe 24. The aeration plate 18 is communicated with the transport pipe 24. On both sides of the outside of the aeration plate 18, a connecting plate 17 is fixedly connected. Two fixed columns 16 are fixedly connected to the inner side wall of the tank body 1. The inner wall of the connecting plate 17 is slidably connected to the outside of the fixed column 16.
[0033] Specifically, the first motor 3 drives the eccentric wheel 14, thereby driving the connecting plate 15 and the aeration plate 18 to perform reciprocating up and down movements. This promotes the mixing of air and sewage, thereby improving the aeration effect. The multiple settings of the aeration heads 19 ensure an increase in the aeration area, enabling oxygen to be more evenly distributed in the sewage, promoting the degradation of organic matter and the metabolism of microorganisms. The sliding connection between the connecting plate 17 and the fixed column 16 ensures the stability and reliability of the aeration plate 18 during the up and down movement, while reducing friction and wear during the movement process. The blower 4 supplies air to the aeration plate 18 through the transport pipe 24, and the reciprocating up and down movement of the aeration plate 18 can increase the contact area and contact time between air and sewage, thereby improving the aeration efficiency. In this design, the aeration plate 18 and the aeration heads 19 can be separately disassembled and replaced, facilitating the maintenance and repair of the aeration device. By improving the aeration efficiency and reducing friction and wear, this design can reduce the energy consumption and operating costs during the sewage treatment process.
[0034] Referring to Figure 4 , Figure 5 and Figure 6, a stirring assembly is arranged above the pool body 1. The stirring assembly includes a fixing frame 5. The bottom of the fixing frame 5 is fixedly connected to the top of the pool body 1. The bottom of the fixing frame 5 is fixedly connected with a mounting frame 7. The inner side of the mounting frame 7 is fixedly connected with a second motor 6. The output end of the second motor 6 is fixedly connected with a connecting rod 12. The inner wall of the connecting rod 12 is fixedly connected with a third motor 20. The output end of the third motor 20 is fixedly connected with a threaded rod 21. The outer part of the threaded rod 21 is threadedly connected with an adapter rod 13. Both the outer parts of the connecting rod 12 and the adapter rod 13 are fixedly connected with two stirring plates 10. The outer part of the stirring plate 10 is fixedly connected with a plurality of stirring blades 11. A chute 22 is formed inside the connecting rod 12. The upper side of the outer part of the adapter rod 13 is fixedly connected with a slider 23. The outer part of the slider 23 is slidably connected to the inner wall of the chute 22. The bottom of the fixing frame 5 is fixedly connected with an adapter frame 9. Both sides of the outer part of the adapter frame 9 are fixedly connected to the inner side wall of the pool body 1. The outer part of the connecting rod 12 is rotatably connected to the inner wall of the adapter frame 9.
[0035] Specifically, the fixing frame 5 serves as the basic structure of the stirring assembly, and its bottom is directly fixed to the top of the pool body 1, ensuring the stability and steadiness of the entire stirring assembly. This connection method can effectively resist various forces and vibrations generated during the stirring process, prevent the stirring assembly from shifting or tilting, and ensure the smooth progress of the stirring process. The mounting frame 7 also provides stable support for the second motor 6, ensuring the stability and reliability of the second motor 6 during operation. After the second motor 6 is started, the connecting rod 12 begins to rotate, driving the stirring plates 10 and the stirring blades 11 to rotate in the pool body 1. At the same time, the third motor 20 drives the threaded rod 21 to rotate, causing the adapter rod 13 to slide up and down in the chute 22, further increasing the complexity and effect of the stirring. This combined movement enables the stirring plates 10 and the stirring blades 11 to generate strong water flow disturbances, breaking the stratification in the sewage and achieving uniform mixing of the sewage. The innovative application of the stirring assembly makes the sewage treatment process more efficient and uniform. The lifting and rotating movements of the stirring plates 10 and the stirring blades 11 not only break the stratification in the sewage but also further promote the contact and reaction between the organic matter and microorganisms in the sewage through strong shear forces and vortices. This mixing and stirring effect improves the efficiency of sewage treatment, accelerates the degradation process, and enables the solids, liquids, and microorganisms in the sewage to be more evenly distributed and treated. The sliding movement of the slider 23 in the chute 22 enables the stirring plates 10 and the stirring blades 11 to move up and down. This design makes the movement of the stirring assembly more flexible. By adjusting the position of the slider 23 in the chute 22, precise control of the stirring depth and stirring range can be achieved to meet different sewage treatment requirements. By fixedly connecting both sides of the outer part of the adapter frame 9 to the inner side wall of the pool body 1, the uniform distribution of the force on the stirring assembly is realized. This helps to reduce the stress and deformation caused by uneven force, improving the service life and reliability of the stirring assembly.
[0036] Refer toFigure 1 and Figure 2 On the left side outside the pool body 1, a water inlet pipe 2 is fixedly connected, and on the right side outside the pool body 1, a water outlet pipe 8 is fixedly connected.
[0037] Specifically, the water inlet pipe 2 is responsible for introducing the sewage to be treated into the aeration tank, which is the first step in the sewage treatment process. After the sewage treatment is completed, the water outlet pipe 8 is responsible for discharging the treated water from the aeration tank.
[0038] Working principle: After starting the blower 4, it continuously inhales external air and transports the air to the inside of the aeration plate 18 through the transport pipe 24. The air passes through the aeration heads 19 to aerate the inside of the pool body 1. At the same time, start the first motor 3. The first motor 3 drives the eccentric wheel 14 to rotate, so that the connecting plate 15 drives the aeration plate 18 to move up and down reciprocally in the pool body 1. This improves the scope and effect of aeration. By starting the second motor 6, it starts to rotate and drives the connecting rod 12 to rotate. The third motor 20 is started simultaneously to drive the threaded rod 21 to rotate. The rotation of the threaded rod 21 causes the connecting rod 13 to slide up and down in the chute 22 of the connecting rod 12. The movement of the connecting rod 13 drives the stirring plate 10 and the stirring blades 11 to move up and down. The up and down movement of the stirring plate 10 and the stirring blades 11 generates water flow disturbance in the pool body 1, breaking the stratification phenomenon in the sewage. The shape and arrangement of the stirring blades 11 enable strong shear forces and vortices to be formed during the stirring process, thus effectively mixing the solids, liquids and microorganisms in the sewage. This enables the organic matter and microorganisms in the sewage to better contact and react, accelerating the degradation process.

Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
