Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a uniform aeration structure. Background Technology

[0002] Aeration refers to the process of introducing air or oxygen into a liquid to increase the oxygen content in the water, thereby improving the dissolved oxygen level of the water body. This process is commonly used in wastewater treatment, aquaculture, and aquariums to promote the growth of beneficial microorganisms in the water and enhance the water body's self-purification capacity.

[0003] Existing aeration structures can contact most of the wastewater in shallower areas of wastewater treatment ponds, but in deeper areas, the higher pressure of the wastewater compresses the gas, preventing it from spreading and expanding, thus preventing the wastewater in deeper areas from contacting the gas to dissolve oxygen. To overcome these disadvantages, this invention provides a uniform aeration structure. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a uniform aeration structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a uniform aeration structure, comprising a sewage treatment tank, a support frame fixedly connected to the top of the sewage treatment tank, a plurality of support blocks fixedly connected to the support frame, a fixed air pipe fixedly connected to the support block, a first rotating air pipe rotatably connected to the air outlet of the fixed air pipe, a second rotating air pipe rotatably connected to the air outlet of the fixed air pipe located on one side of the first rotating air pipe, a power component provided at the top of the sewage treatment tank, a transmission component provided on the second rotating air pipe, and an aeration component provided at the bottom of the first and second rotating air pipes.

[0006] Furthermore, a first sealing ring is provided on the air outlet of the fixed air pipe that is rotatably connected to the first rotating air pipe, and a second sealing ring is provided on the air outlet of the fixed air pipe that is rotatably connected to the second rotating air pipe.

[0007] Furthermore, the power assembly includes a servo motor fixedly connected to the top of the sewage treatment tank, a fourth pulley fixedly connected to the output end of the servo motor, a first pulley fixedly connected to the first rotating air pipe, and the first pulley and the fourth pulley are driven by a second belt.

[0008] Furthermore, the transmission assembly includes a third pulley fixedly connected to the second rotating air pipe, and the second pulley is fixedly connected to the first rotating air pipe. The second pulley and the third pulley are driven by a first belt.

[0009] Furthermore, the aeration assembly includes a hollow disc disposed at the bottom end of the first rotating air pipe and the second rotating air pipe. A first air port is provided at the top of the hollow disc. The first air port is fixedly connected to the bottom end of the first rotating air pipe and the second rotating air pipe. A plurality of second air ports are provided on the side of the hollow disc. An aeration pipe is fixedly connected to each of the second air ports. A plurality of aeration ports are provided on the aeration pipe.

[0010] Furthermore, several air pumps are fixedly connected to the top of the sewage treatment tank, and the air pump inlets are fixedly connected to one end of the fixed air pipe.

[0011] The beneficial effects of this utility model are:

[0012] In use, this utility model employs a uniform aeration structure. Due to the high pressure at the bottom of the water, the sprayed gas is compressed and cannot expand, preventing the bottom sewage from contacting the air and dissolving oxygen. However, through the rotation of multiple aeration ports and the first and second rotating air pipes on the device, the sewage in the sewage treatment tank is uniformly aerated, ensuring that all the sewage in the sewage treatment tank can contact the air and dissolve oxygen.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-3 As shown, a uniform aeration structure is disclosed, comprising a sewage treatment tank 1, a support frame 2 fixedly connected to the top of the sewage treatment tank 1, several support blocks 3 fixedly connected to the support frame 2, a fixed air pipe 5 fixedly connected to the support block 3, a first rotating air pipe 8 rotatably connected to the air outlet on the fixed air pipe 5, and a second rotating air pipe 11 rotatably connected to the air outlet on the fixed air pipe 5 located on one side of the first rotating air pipe 8. A power component is provided at the top of the sewage treatment tank 1, a transmission component is provided on the second rotating air pipe 11, and an aeration component is provided at the bottom of the first rotating air pipe 8 and the second rotating air pipe 11.

[0021] like Figure 1-3 As shown, a first sealing ring 6 is provided at the air outlet on the fixed air pipe 5 and rotatably connected to the first rotating air pipe 8, and a second sealing ring 7 is provided at the air outlet on the fixed air pipe 5 and rotatably connected to the second rotating air pipe 11, so that gas does not leak from the rotatable connection between the first rotating air pipe 8, the second rotating air pipe 11 and the fixed air pipe 5.

[0022] like Figure 1-3 As shown, the power assembly includes a servo motor 14 fixedly connected to the top of the sewage treatment tank 1, a fourth pulley 15 fixedly connected to the output end of the servo motor 14, a first pulley 9 fixedly connected to the first rotating air pipe 8, and a second belt 16 driving the first pulley 9 and the fourth pulley 15 to provide power for the rotation of the first rotating air pipe 8.

[0023] like Figure 1-3 As shown, the transmission assembly includes a third pulley 12 fixedly connected to the second rotating air pipe 11, and a second pulley 10 fixedly connected to the first rotating air pipe 8. The second pulley 10 and the third pulley 12 are driven by a first belt 13 to transmit power to the second rotating air pipe 11 and make it rotate.

[0024] like Figure 1-3As shown, the aeration assembly includes a hollow disc 17 disposed at the bottom of the first rotating air pipe 8 and the second rotating air pipe 11. A first air port 20 is opened at the top of the hollow disc 17. The first air port 20 is fixedly connected to the bottom of the first rotating air pipe 8 and the second rotating air pipe 11. Several second air ports 21 are opened on the side of the hollow disc 17. An aeration pipe 18 is fixedly connected to the second air port 21. Several aeration ports 19 are opened on the aeration pipe 18 for aeration of the sewage treatment tank 1.

[0025] like Figure 1-3 As shown, several air pumps 4 are fixedly connected to the top of the sewage treatment tank 1. The air pump 4 has its air inlet and one end of a fixed air pipe 5 fixedly connected to provide compressed air for the device during aeration.

[0026] Working principle: When using the device, first check if the entire device is intact. After the check is completed, start the air pump 4. The air compressed by the air pump 4 passes through the fixed air pipe 5, the first rotating air pipe 8, the second rotating air pipe 11, the hollow disc 17 and the aeration pipe 18, and finally sprays out from the bottom of the sewage treatment tank 1 through the aeration port 19. Then, start the servo motor 14. The servo motor 14 drives the fourth pulley 15 to rotate. The fourth pulley 15 drives the first pulley 9 to rotate through the second belt 16, which in turn drives the first rotating air pipe 8 to rotate. The rotation of the first rotating air pipe 8 drives the second pulley 10 to rotate, and then drives the third pulley 12 to rotate through the first belt 13, which in turn drives the second rotating air pipe 11 to rotate. The rotation of the first rotating air pipe 8 and the second rotating air pipe 11 allows the sewage at the bottom of the sewage treatment tank 1 to come into contact with the air evenly.
