Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater treatment aeration device with self-cleaning function. Background Technology

[0002] Most aeration devices have a filter structure at the water inlet to intercept suspended impurities in the wastewater. However, these impurities tend to adhere to the surface of the filter components and gradually accumulate, causing blockage of the water inlet pipe and a decrease in water flow. Existing devices need to be shut down regularly for manual cleaning or replacement of filter components, which not only increases operation and maintenance costs and labor intensity, but also interrupts the wastewater treatment process and reduces overall treatment efficiency. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this invention provides a wastewater treatment aeration device with a self-cleaning function, solving the problem of the inability to self-clean.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wastewater treatment aeration device with a self-cleaning function, comprising: an inlet component, wherein a collection chamber is connected through the outer wall below the inlet component, and the end of the inlet component away from the collection chamber extends into the interior of an air suction chamber, the inner wall of the air suction chamber being fixedly connected to the outer wall of the inlet component; the inlet component includes an inlet pipe, a filter plate is rotatably connected inside the inlet pipe, a shaft is fixedly connected to the outer wall of the filter plate, blades are fixedly connected to the outer wall of the shaft, a rotating shaft is fixedly connected to the outer wall of the filter plate, and a cleaning rod is rotatably connected to the outer wall below the rotating shaft, the cleaning rod being slidably connected to... The guide rod, with a return spring internally slidably connected, effectively intercepts suspended impurities in the wastewater by installing a filter plate inside the inlet pipe, preventing impurities from entering subsequent components and causing blockages, thus improving the overall stability of the device's operation. The water flow drives the blades to rotate, assisting wastewater flow without additional power, reducing energy consumption. The cleaning rod, guide rod, and return spring work together to automatically clean impurities from the filter plate surface, eliminating the need for manual cleaning during downtime, reducing maintenance costs and labor intensity, ensuring the continuity of the wastewater treatment process, and improving treatment efficiency. The collection chamber promptly collects the cleaned impurities, preventing their accumulation in the inlet pipe and further ensuring its unobstructed flow.

[0007] Preferably, the inlet pipe has multiple tapered sections to accelerate wastewater removal. The telescopic ends of the guide rod are slidably connected to the inner wall of the inlet pipe. The outer wall of the shaft is rotatably connected to the inner wall of the inlet pipe via a support frame. A discharge port for the collection chamber is provided through the lower outer wall of the inlet pipe. An air intake port is connected through the upper outer wall of the air intake chamber. A mixing component is connected through the end of the air intake chamber away from the inlet pipe. The tapered structure of the inlet pipe accelerates wastewater removal, enhancing the impact of water flow on impurities on the filter plate and assisting the cleaning rod in cleaning impurities. It also provides a suitable flow rate for subsequent gas-liquid mixing, improving the mixing effect. The sliding connection between the guide rod and the inner wall of the inlet pipe ensures that the cleaning rod cleans the filter plate stably and efficiently, avoiding incomplete cleaning due to the shaking of the cleaning rod. The support frame supports the shaft, ensuring the stability of the blade rotation, continuously assisting the wastewater flow, and further reducing energy consumption. The air intake port is designed to stably introduce air into the air intake chamber, allowing the wastewater to be initially mixed with air before entering the mixing component, laying the foundation for subsequent efficient mixing.

[0008] Preferably, the mixing assembly includes a mixing chamber, inside which a first mixing plate is fixedly connected. The inner wall of the first mixing plate has multiple sets of irregularly shaped holes. A rotating rod is rotatably connected to the side of the first mixing plate away from the intake chamber. A mixing blade is fixedly connected to the outer wall of the rotating rod. A second mixing plate is rotatably connected to the end of the rotating rod away from the first mixing plate. The second mixing plate has a gourd-shaped opening inside. A corrugated plate is fixedly connected inside the mixing chamber. An acceleration chamber is connected through the end of the mixing chamber away from the intake chamber. The corrugated plate in the mixing chamber prolongs the residence time of the gas-liquid mixture, thus facilitating subsequent... Multiple mixing steps provide ample time to enhance the thoroughness of mixing. The irregularly shaped holes in the first mixing plate achieve the initial diversion and mixing of the gas-liquid mixture, changing the flow direction, breaking the gas-liquid stratification, and initially improving the mixing effect. The mixing blades rotate with the flow of the gas-liquid mixture, stirring the mixture without additional power, reducing energy consumption while further promoting gas-liquid mixing. The gourd-shaped opening of the second mixing plate achieves the secondary diversion and mixing of the gas-liquid mixture, enhancing the contact and diffusion between gas and liquid through changes in flow velocity, ultimately achieving efficient gas-liquid mixing, providing favorable conditions for subsequent aeration treatment, and improving the wastewater treatment effect.

[0009] Preferably, the acceleration chamber includes an acceleration tube, and a spiral rod is rotatably connected inside the acceleration tube via a support frame. A diffuser tube is connected through the end of the acceleration tube away from the mixing chamber. The acceleration tube accelerates the gas-liquid mixture, enabling it to quickly reach the treatment area and improving wastewater treatment efficiency. The spiral rod rotates under the influence of the gas-liquid mixture, requiring no additional power for propulsion and stirring, reducing the energy consumption of the device while ensuring uniform gas-liquid mixing and preventing gas-liquid stratification due to acceleration. The diffuser tube evenly diffuses the gas-liquid mixture, ensuring that dissolved oxygen is evenly distributed in the wastewater treatment area, guaranteeing sufficient oxygen for microorganisms within the area, improving pollutant degradation, and thus enhancing wastewater treatment quality.

[0010] (III) Beneficial Effects

[0011] This invention provides a wastewater treatment aeration device with a self-cleaning function. It has the following beneficial effects:

[0012] (i) This wastewater treatment aeration device with self-cleaning function drives the cleaning rod to rotate around the rotating shaft through water flow. With the trajectory restriction of the guide rod and the reset action of the return spring, it can continuously clean the impurities attached to the surface of the filter plate and avoid filter plate blockage. At the same time, the cleaned impurities fall into the collection bin through the discharge port of the inlet pipe for temporary storage. There is no need to frequently stop the machine to manually clean the filter components, which effectively reduces the manpower input and equipment downtime during operation and maintenance, reduces the overall operation and maintenance cost, and ensures the continuity of the wastewater treatment process.

[0013] (II) This wastewater treatment aeration device with self-cleaning function accelerates wastewater through the conical structure of the inlet pipe, where it is initially mixed with air in the suction chamber. After entering the mixing chamber, the wastewater undergoes a process of extending the residence time through a corrugated plate, diverting the flow through irregularly shaped holes in the first mixing plate, stirring with mixing blades, and secondary diversion through the gourd-shaped opening of the second mixing plate, achieving efficient gas-liquid mixing. Finally, the wastewater is accelerated by the acceleration pipe and assisted by the screw rod, and then evenly diffused to the treatment area through the diffusion pipe. The multi-stage mixing and uniform diffusion design significantly improves the gas-liquid contact area and mixing uniformity, providing sufficient dissolved oxygen for microorganisms in the wastewater and effectively improving the pollutant degradation efficiency and wastewater treatment quality.

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution for a wastewater treatment aeration device with self-cleaning function, including: an inlet component 1, a collection chamber 6 is connected through the outer wall below the inlet component 1, one end of the inlet component 1 away from the collection chamber 6 extends into the interior of the air suction chamber 2, and the inner wall of the air suction chamber 2 is fixedly connected to the outer wall of the inlet component 1; the inlet component 1 includes an inlet pipe 11, a filter plate 12 is rotatably connected inside the inlet pipe 11, a shaft 13 is fixedly connected to the outer wall of the filter plate 12, blades 14 are fixedly connected to the outer wall of the shaft 13, a rotating shaft 17 is fixedly connected to the outer wall of the filter plate 12, a cleaning rod 15 is rotatably connected to the outer wall below the rotating shaft 17, a guide rod 16 is slidably connected inside the cleaning rod 15, and a return spring 18 is slidably connected inside the guide rod 16.

[0021] The inlet pipe 11 has multiple tapered sections to accelerate the removal of wastewater. The telescopic ends of the guide rod 16 are slidably connected to the inner wall of the inlet pipe 11. The outer wall of the shaft 13 is rotatably connected to the inner wall of the inlet pipe 11 through a support frame. The outer wall below the inlet pipe 11 has a discharge port that cooperates with the collection chamber 6. The outer wall above the air suction chamber 2 is connected to an air suction port. The end of the air suction chamber 2 away from the inlet pipe 11 is connected to a mixing component 3.

[0022] The mixing assembly 3 includes a mixing chamber 31. A first mixing plate 33 is fixedly connected inside the mixing chamber 31. Multiple sets of irregularly shaped holes are opened on the inner wall of the first mixing plate 33. A rotating rod 36 is rotatably connected to the side of the first mixing plate 33 away from the air intake chamber 2. A mixing blade 37 is fixedly connected to the outer wall of the rotating rod 36. A second mixing plate 34 is rotatably connected to the end of the rotating rod 36 away from the first mixing plate 33. A gourd-shaped opening 35 is opened inside the second mixing plate 34. A corrugated plate 32 is fixedly connected inside the mixing chamber 31. An acceleration chamber 4 is connected through the end of the mixing chamber 31 away from the air intake chamber 2.

[0023] The acceleration chamber 4 includes an acceleration tube 41, and a spiral rod 43 is rotatably connected inside the acceleration tube 41 via a support frame. A diffuser tube 42 is connected through the end of the acceleration tube 41 away from the mixing chamber 31.

[0024] In use, the wastewater to be treated first enters the inlet pipe 11 of the inlet assembly 1. When it flows through the filter plate 12, the filter plate 12 intercepts suspended impurities in the wastewater. During the flow of wastewater, it impacts the blades 14 on the shaft 13, causing the blades 14 and the shaft 13 to rotate, which helps to push the wastewater to flow in the inlet pipe 11. At the same time, the water flow causes the cleaning rod 15 to rotate around the rotating shaft 17 on the filter plate 12. The guide rod 16 restricts the rotation trajectory of the cleaning rod 15 to ensure that it is in full contact with the surface of the filter plate 12 and cleans the impurities attached to the filter plate 12. When the cleaning rod 15 rotates to a certain angle, the return spring 18 in the guide rod 16 is squeezed and generates elastic force, which drives the cleaning rod 15 to rotate in the opposite direction to reset, so as to continuously clean the filter plate 12. The cleaned impurities fall into the collection chamber 6 through the discharge port below the inlet pipe 11, completing the collection and temporary storage of impurities.

[0025] Because the inlet pipe 11 has a conical structure in many places, the sewage is accelerated when it flows through these parts, forming a flow state with different flow rates. This not only enhances the impact effect on impurities, but also provides suitable water flow conditions for subsequent treatment. The pre-treated sewage is discharged from the end of the inlet pipe 11 and enters the air intake chamber 2. At the same time, external air enters the chamber through the air intake port above the air intake chamber 2. The sewage and air are initially contacted and mixed in the air intake chamber 2.

[0026] The initially mixed gas-liquid mixture enters the mixing chamber 31 of the mixing component 3. Under the action of the corrugated plate 32, the flow path changes, prolonging the residence time in the mixing chamber 31. Subsequently, the gas-liquid mixture flows through the first mixing plate 33 and is diverted through multiple sets of irregular holes on its inner wall, changing the flow direction and achieving the first thorough mixing. Then, the gas-liquid mixture impacts the mixing blades 37 on the rotating rod 36, causing the rotating rod 36 and the mixing blades 37 to rotate, stirring the mixture and further promoting mixing. Afterward, the mixture passes through the gourd-shaped opening 35 of the second mixing plate 34. Under the contraction and expansion of the opening, the flow velocity changes, forming a secondary diversion mixing. Finally, efficient gas-liquid mixing is completed in the mixing chamber 31.

[0027] The mixed gas-liquid mixture enters the acceleration tube 41 of the acceleration chamber 4. As it flows within the acceleration tube 41, its speed gradually increases. Simultaneously, the mixture drives the spiral rod 43 inside the acceleration tube 41 to rotate. The spiral rod 43 generates propulsion force during rotation, which assists in pushing the mixture to flow and stirring it again, ensuring uniform mixing. Finally, the accelerated gas-liquid mixture is diffused and discharged through the diffuser tube 42, evenly distributed in the wastewater treatment area, providing sufficient dissolved oxygen for the microorganisms in the wastewater and achieving the aeration treatment effect.
