[0002] The sewage aeration device is a device used to increase oxygen in the sewage treatment process. It provides sufficient oxygen supply by introducing oxygen into the wastewater, promotes biodegradation reactions, and accelerates the removal of pollutants. In addition, the aeration device can also prevent the suspended matter in the pool from sinking and strengthen the contact between organic matter and microorganisms and dissolved oxygen in the pool. It is widely used and is commonly found in urban sewage treatment plants, industrial wastewater treatment facilities, and rural domestic sewage treatment.

[0003] However, after long-term use, the existing aeration device often becomes clogged due to the mixture of microorganisms, algae, and yin and yang substances inside the sewage pool, thus affecting the use effect. In order to solve the above problem, while facilitating efficient aeration of the sewage pool and accelerating the removal of pollutants inside the sewage, the aeration device can be avoided from being clogged during use, which facilitates the long-term use of the aeration device. For this reason, we have proposed a high-efficiency aeration device for sewage treatment. Utility Model Content

[0027] An aeration device, which is arranged at the bottom of the air guide box 5 and is used to discharge diffused oxygen;

[0028] A cleaning component is arranged on the outside of the air guide box 5 and is used to prevent the aeration device from being blocked and affecting its use.

[0029] Furthermore, a plurality of grids 6 for air intake and blocking debris are equidistantly provided on the air hood 3 .

[0030] Furthermore, a floating plate 7 is fixedly mounted on the outer wall surface of the bottom of the floating box 1 , and an air cavity 8 which is an inclined surface is formed at the bottom of the floating plate 7 .

[0031] Furthermore, a number of air bags 9 for increasing buoyancy and maintaining stability are equidistantly fixedly installed inside the air cavity 8. The arrangement of the float 7, the air cavity 8 and the air bags 9 increases the buoyancy of the device and ensures the stability of the device in water during use, thereby preventing the device from shaking or changing its position due to water flow fluctuations, and making it more convenient to use when aerating the sewage pool.

[0032] Furthermore, the aeration device includes an air storage plate 10, an air diffusion slot plate 11 and an air diffusion grid 12. The bottom of the air guide box 5 is connected to the air storage plate 10 through a connecting pipe. The air storage plate 10 is conical in shape as a whole, and the interior of the air storage plate 10 is hollow. A plurality of air diffusion slot plates 11 for air diffusion are fixedly installed at equal intervals on the top of the air storage plate 10. The top and side of the air diffusion slot plate 11 are provided with an air diffusion grid 12 for dispersing oxygen. Through the setting of the aeration device, when in use, the air pump 2 sucks the air from the outside, and the air is transmitted through the transmission pipe 4. The oxygen enters the interior of the air guide box 5, and the protection cover inside the air guide box 5 can prevent oxygen from leaking from the inside 5. Then, the oxygen is sent to the interior of the gas storage disk 10 through the connecting pipe at the bottom of the air guide box 5, and then the oxygen is dispersed through the air diffusion slot plate 11 fixedly installed on the top of the gas storage disk 10. When passing through several grids of the air diffusion grid 12, the oxygen is dispersed into more fine bubbles, which can effectively discharge the oxygen and diffuse it into the sewage, thereby improving the aeration efficiency, thereby promoting the microbial activity in the sewage, and contributing to the biological treatment process of the sewage, which is more convenient and practical.

[0033] Furthermore, the cleaning assembly includes a driving gear 13, a connecting gear ring 14 and a cleaning rod 15. A driving motor for driving is fixedly installed inside the air guide box 5, and a driving gear 13 is fixedly installed on the output end of the driving motor. A protective cover for sealing the driving motor is fixedly installed at the position corresponding to the driving motor and the driving gear 13 inside the air guide box 5. A connecting gear ring 14 is slidably installed on the outer side of the air guide box 5, and the driving gear 13 is meshed with the connecting gear ring 14. A plurality of cleaning rods 15 for cleaning are fixedly installed at equal intervals on the bottom of the connecting gear ring 14.

[0034] Furthermore, an L-shaped cleaning strip 16 is fixedly installed at the bottom of the cleaning rod 15, and a foam strip 17 for cleaning is fixedly installed on the side where the cleaning strip 16 contacts the air diffusion slot plate 11. Through the setting of the cleaning component, after the aeration device has been used for a period of time, some algae, dirt and other debris may be attached to the surface of the air diffusion grid 12 due to intermittent use. When used for aeration, the grids on the air diffusion grid 12 may be blocked, affecting the use of the aeration device. Therefore, it is necessary to start the driving motor to drive the driving gear 13 to rotate, and through the cooperation between the driving gear 13 and the connecting gear ring 14, the connecting gear ring 14 is driven to slide on the outer wall surface of the air guide box 5, thereby driving the cleaning rod 15 fixedly installed at the bottom of the connecting gear ring 14 to slide with it, and driving the cleaning strip 16 fixedly installed at the bottom of the cleaning rod 15 to rotate around a number of air diffusion slot plates 11, so that the dirt on the surface is cleaned through the foam strip 17 fixedly installed on the other side of the cleaning strip 16, which can effectively prevent the aeration device from being blocked, ensure the stability of the aeration device during long-term use, and be more practical.

[0035] Instructions

After confirming the sealing, it can be used. When in use, start the air pump 2 to suck the outside air, and transmit it into the interior of the air guide box 5 through the transmission pipe 4. Then, send the oxygen to the interior of the gas storage disk 10 through the connecting pipe at the bottom of the gas guide box 5, and then disperse the oxygen through the air diffusion trough plate 11 fixedly installed on the top of the gas storage disk 10, and disperse the oxygen into more fine bubbles when passing through several grids of the air diffusion grid 12, which can effectively discharge and diffuse the oxygen into the sewage, thereby improving the aeration efficiency. After the aeration device has been used for a period of time, some algae, dirt and other debris may be attached to the surface of the air diffusion grid 12 due to intermittent use, which may block the air diffusion when it is used for aeration. The grids on the grid 12 affect the use of the aeration device, so it is necessary to start the driving motor to drive the driving gear 13 to rotate, and through the cooperation between the driving gear 13 and the connecting gear ring 14, drive the connecting gear ring 14 to slide on the outer wall surface of the air guide box 5, thereby driving the cleaning rod 15 fixedly installed at the bottom of the connecting gear ring 14 to slide with it, and driving the cleaning strip 16 fixedly installed at the bottom of the cleaning rod 15 to rotate around a number of air dispersion slots 11, so that the foam strip 17 fixedly installed on the other side of the cleaning strip 16 can clean the dirt on the surface, which can effectively prevent the aeration device from being blocked and effectively ensure the stability of the aeration device during long-term use. Through the mutual cooperation between the above-mentioned structures, the device facilitates efficient aeration of the sewage pool and accelerates the removal of pollutants inside the sewage, while avoiding the problem of blockage of the aeration device during use, which is convenient for long-term use of the aeration device and more practical.
