The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This utility model embodiment provides an aeration device for sewage treatment, such as... Figure 1-4 As shown, the aeration device for wastewater treatment includes: an aeration tank 1 for storing wastewater; multiple support frames 2 installed inside the aeration tank 1; a pipe assembly 3 installed on the multiple support frames 2 and located inside the aeration tank 1 for transporting gas; multiple cleaning plates 13 movably sleeved outside the pipe assembly 3 for cleaning impurities attached to the outside of the pipe assembly 3; and multiple driving components disposed at the top of the aeration tank 1 for adjusting the cleaning position of the cleaning plates 13.

[0022] In this embodiment, the aeration tank 1 is used to store the sewage to be treated, the support frame 2 is used to support the pipe assembly 3 to ensure that the pipe assembly 3 can be stably located in the sewage, the pipe assembly 3 is used to transport gas into the sewage to increase the air content in the sewage and promote sewage treatment, the cleaning plate 13 is used to clean the impurities attached to the outer surface of the pipe assembly 3, which can prevent the impurities from accumulating over a long period of time and causing pipe corrosion, and the drive component is used to adjust the cleaning position of the cleaning plate 13. Through the drive component, the movement of the cleaning plate 13 on the pipe assembly 3 can be controlled, thereby achieving cleaning of the entire outer surface of the pipe assembly 3.

[0023] In a further preferred embodiment of this utility model, the driving assembly includes a threaded rod 10, a servo motor 11, and two sliding plates 12. Support plates 4 are provided on both sides of the aeration tank 1, and mounting plates 6 are fixed to the top of the two support plates 4. The threaded rod 10 is rotatably mounted between the two mounting plates 6. The servo motor 11 is mounted on the top of any one of the support plates 4, and the output shaft of the servo motor 11 is connected to the threaded rod 10. The two sliding plates 12 are threaded onto the threaded rod 10, and the two sliding plates 12 are respectively connected to any two cleaning plates 13.

[0024] In this embodiment, the threaded rod 10 serves as a transmission component, driving the slide plate 12 to move through its rotation. The servo motor 11 provides power to drive the threaded rod 10 to rotate. When the threaded rod 10 rotates, the slide plate 12 moves along the axial direction of the threaded rod 10 due to the action of the thread. The support plate 4 is used to mount the mounting plate 6 and the servo motor 11, providing support for the entire drive assembly. The mounting plate 6 is used to mount the threaded rod 10, ensuring that the threaded rod 10 can rotate stably. When the slide plate 12 moves, it drives the cleaning plate 13 to move, thereby achieving the cleaning of the outer surface of the pipe assembly 3. By driving the threaded rod 10 to rotate through the servo motor 11, and then driving the slide plate 12 and the cleaning plate 13 to move, the automated cleaning of the outer surface of the pipe assembly 3 is achieved, improving cleaning efficiency and convenience.

[0025] In a further preferred embodiment of the present invention, each of the plurality of cleaning plates 13 is provided with an opening sleeved outside the pipe assembly 3, and a cleaning pad 14 is installed in each of the plurality of openings. Each of the plurality of cleaning pads 14 is provided with bristles, and a filter screen 9 for preliminary filtration of sewage is installed in the aeration tank 1.

[0026] In this embodiment, the opening allows the cleaning plate 13 to fit tightly against the outer surface of the pipe assembly 3 without affecting the gas delivery. The cleaning pad 14 is in direct contact with the outer surface of the pipe assembly 3 and is provided with bristles. These bristles can more effectively remove impurities attached to the outer surface of the pipe assembly 3. The filter screen 9 is used to initially filter large particulate impurities in the sewage to prevent these impurities from entering between the pipe assembly 3 and the cleaning plate 13 and affecting the cleaning effect. By enhancing the cleaning effect and extending the service life of the pipe assembly 3, the embodiment of this utility model can reduce the maintenance cost and replacement frequency of the equipment.

[0027] In a further preferred embodiment of the present invention, multiple sliders 7 are slidably mounted on both mounting plates 6, and a protective cover 8 is fixed between the multiple sliders 7. The protective cover 8 is used to isolate falling impurities and also to reduce the spread of odors.

[0028] In this embodiment, the slider 7 can slide along a specific track on the mounting plate 6, providing stable support and a movement path for the protective cover 8. The protective cover 8 covers the pipe assembly 3 and the cleaning plate 13 to isolate falling impurities and extend the service life of the equipment. Since the protective cover 8 covers the pipe assembly 3 and the cleaning area, it can also reduce the diffusion of odors generated during sewage treatment into the surrounding environment, improving the working environment and air quality.

[0029] In a further preferred embodiment of this utility model, the pipe assembly 3 consists of multiple horizontal pipes 15, multiple connecting pipes 16, and an extension hose 17. The multiple horizontal pipes 15 are respectively installed on multiple support frames 2, the multiple connecting pipes 16 are respectively installed on multiple horizontal pipes 15, and the extension hose 17 is installed on any one of the horizontal pipes 15 and extends to the outside of the aeration tank 1. The extension hose 17 can be connected to the exhaust end of the high-pressure blower.

[0030] In this embodiment, the horizontal pipes 15 are arranged in parallel and extend along the length of the aeration tank 1. The horizontal pipes 15 are provided with air outlets for releasing gas into the sewage. The connecting pipes 16 are used to connect adjacent horizontal pipes 15 to form a continuous aeration network. In this way, gas can flow between the horizontal pipes 15 through the connecting pipes 16 to achieve a more uniform aeration effect. The extension hose 17 is flexible and extensible, which facilitates connection to the exhaust end of the high-pressure blower. The high-pressure blower supplies gas to the pipeline group 3 through the extension hose 17.

[0031] In a further preferred embodiment of the present invention, each of the plurality of threaded rods 10 is provided with two threaded segments in opposite directions, the plurality of sliding plates 12 are respectively located on the plurality of different threaded segments, and the bottom of each of the two support plates 4 is provided with a plurality of fixed cones 5 that can be inserted into the ground.

[0032] In this embodiment, the thread directions at different positions on the same threaded rod 10 are opposite. This design allows two slide plates 12 to be installed on the same threaded rod 10, and these slide plates 12 will move in opposite directions when the threaded rod 10 rotates. The design of the fixing cone 5 enables the support plate 4 to be firmly fixed to the ground, preventing the equipment from shifting or tilting due to vibration or external force during the sewage treatment process.

[0033] In a further preferred embodiment of the present invention, limiting plates are provided on both sides of the two mounting plates 6, and limiting grooves are provided on both sides of the inner walls of the plurality of sliders 7, and the two limiting plates slide in contact with the inner walls of the plurality of limiting grooves respectively.

[0034] In this embodiment, the function of the limiting plate is to limit the movement range of the slider 7 on the mounting plate 6, ensuring that the slider 7 can slide stably along the predetermined track. When the slider 7 slides on the mounting plate 6, the limiting plate will slide and contact the inner wall of the limiting groove. The design of the limiting groove further enhances the stability of the slider 7 on the mounting plate 6, preventing the slider 7 from deviating or falling off during movement.

[0035] In summary, compared with related technologies, this device, through the design of the drive components, achieves precise adjustment of the position of the cleaning plate 13, thereby efficiently cleaning impurities on the outer surface of the pipe assembly 3, preventing the accumulation of impurities and corrosion of the pipes, and extending the service life of the equipment. The introduction of the servo motor 11 automates the cleaning process, reduces manual intervention, and improves work efficiency and ease of operation. The design of the protective cover 8 not only isolates falling impurities but also reduces the diffusion of odors generated during sewage treatment into the surrounding environment, improving the working environment and air quality. The pipe assembly 3 consists of multiple horizontal pipes 15, connecting pipes 16, and extension hoses 17, forming a continuous aeration network, achieving a more uniform aeration effect and improving the efficiency of sewage treatment.
