[0002] Aeration refers to increasing the contact area between water and air by aerating or mechanically stirring water. It is an intermediate process for aerobic biological treatment of wastewater. With the continuous development of industry, the discharge of sewage is increasing. If sewage is not treated before discharge, it will have a certain impact on the natural environment, which may affect people's production and living conditions. The existing sewage treatment equipment is not environmentally friendly during the sewage treatment process, and the treatment of organic matter and microorganisms in the sewage is not sufficient during the treatment process, which can easily lead to poor sewage treatment effects.

[0005] Furthermore, it also includes a rotating shaft, a gear, a rack and a rotating paddle. The upper end of the scraper is rotatably connected to the rotating shaft, one end of the rotating shaft is fixedly connected to the gear, the rack is fixedly connected to the top of the sewage pool, the rack and the gear are meshed, and a number of rotating paddles are fixedly connected to the rotating shaft.

[0006] Furthermore, it also includes an air inlet pipe and a one-way valve. One end of each air supply pipe located inside the sewage pool is fixedly connected to an air inlet pipe, and each air inlet pipe is fixedly connected to three one-way valves.

[0007] Furthermore, it also includes a guide plate, a guide rod, a fixed rod and a movable plate. The other end of the rotating shaft is fixedly connected to the guide plate, a groove is opened on the guide plate, the movable plate is slidably connected to the scraper, the movable plate is fixedly connected to the fixed rod, the fixed rod is fixedly connected to the guide rod, and the other end of the guide rod is slidably connected to the groove of the guide plate.

[0008] The beneficial effect is: through the action of the one-way valve on the air inlet pipe, the oxygen in the air supply pipe can enter the sewage pool, while the wastewater in the sewage pool will not enter the air supply pipe through the air inlet pipe, and the rotating paddle is driven by the rotating shaft to reciprocate left and right. The rotation of the rotating paddle will stir the wastewater, so that oxygen and microorganisms are fully in contact, and the moving plate is used to stir the wastewater and the sludge and microorganisms at the bottom of the sewage pool, so that oxygen and microorganisms are in more complete contact, thereby making the wastewater treatment effect better.

[0014] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] Example 1

[0016] An environmentally friendly sewage aeration device, such as Figure 1-4 As shown, it includes a sewage pool 1, an air pipe 2, a scraper 3, a piston 4 and a push rod 6. The two side walls of the sewage pool 1 are connected to an air pipe 2, and the air pipe 2 is located on the left and right sides of the sewage pool 1. A piston 4 is slidably connected in each air pipe 2, and a push rod 6 is fixedly connected between the two pistons 4. The push rod 6 is used to push the two pistons 4 to move left and right. The scraper 3 is fixedly connected to the push rod 6, and the scraper 3 is located at the bottom of the sewage pool 1.

[0017] Example 2

[0018] On the basis of Example 1, Figure 1-4As shown, it also includes a rotating shaft 7, a gear 8, a rack 9 and a rotating paddle 10. The upper end of the scraper 3 is rotatably connected to the rotating shaft 7 through a bearing. The rotating shaft 7 is parallel to the bottom surface of the sewage tank. One end of the rotating shaft 7 is fixedly connected to the gear 8. The gear 8 is located at the right end of the rotating shaft 7. The rack 9 is fixedly connected to the right side of the top of the sewage tank 1. The rack 9 and the gear 8 are meshed. A number of rotating paddles 10 are fixedly connected to the rotating shaft 7. The rotating paddles 10 are used to stir the sewage in the sewage tank.

[0019] Example 3

[0020] On the basis of Example 2, Figure 1-4 As shown, it also includes an air intake pipe 11 and a one-way valve 111. One end of each air supply pipe 2 located inside the sewage pool 1 is fixedly connected to an air intake pipe 11, and each air intake pipe 11 is fixedly connected to three one-way valves 111. The air supply pipe 2 can transport air into the sewage pool through the air intake pipe 11, and the one-way valve 111 is used to prevent sewage in the sewage pool from entering the air supply pipe 2 through the air intake pipe 11.

[0021] It also includes a guide plate 12, a guide rod 13, a fixed rod 14 and a movable plate 15. The other end of the rotating shaft 7 is fixedly connected to the guide plate 12, the guide plate 12 is located on the left side of the rotating shaft 7, and a groove is opened on the guide plate 12. The movable plate 15 is slidably connected to the scraper 3. The movable plate 15 is parallel to the rotating shaft 7. The fixed rod 14 is fixedly connected to the movable plate 15. The fixed rod 13 is fixedly connected to the guide rod 13. The other end of the guide rod 13 is slidably connected to the groove of the guide plate 12.

[0022] When it is necessary to aerate the wastewater during the sewage treatment process, the staff connects the air pipes 2 on both sides of the sewage pool 1 in turn, and the air in the air pipe 2 pushes the piston 4 to move back and forth. When the piston 4 moves to enable the air pipe 2 to be connected with the air inlet pipe 11, the air in the air pipe 2 enters the sewage pool 1 through the one-way valve 111 on the air inlet pipe 11. Through the action of the one-way valve 111, the wastewater in the sewage pool 1 will not enter the air pipe 2 through the air inlet pipe 11. The reciprocating movement of the piston 4 will drive the push rod 6 to move back and forth, the push rod 6 will drive the scraper 3 to move back and forth, the scraper 3 will drive the rotating shaft 7 to move back and forth, and the rotating shaft 7 will move back and forth. The moving shaft 7 will drive the gear 8 to move back and forth and rotate on the rack 9. At the same time, the rotating shaft 7 will drive the rotating paddle 10 and the guide plate 12 to rotate back and forth. The rotation of the rotating paddle 10 will stir the wastewater, so that the oxygen in the air will fully contact with the microorganisms. The guide plate 12 will drive the guide rod 13 to move back and forth. The guide rod 13 will drive the fixed rod 14 to move back and forth while moving up and down. The fixed rod 14 will drive the moving plate 15 to move up and down. The moving plate 15 can stir the wastewater and the sludge and microorganisms at the bottom of the sewage pool 1, so that the oxygen in the air will contact with the microorganisms more fully, thereby making the wastewater treatment effect better.

[0023] After the inflation is completed, the staff will shut off the oxygen connected to the gas pipe 2, and the sewage aeration process is completed.
