Description
Technical Field
[0001] This utility model relates to the field of aeration disc technology, and in particular to an aeration disc anti-clogging air distribution device. Background Technology
[0002] Aeration discs are key components in wastewater treatment aeration devices. They are mostly disc-shaped structures that release air into the water through air distribution holes. Their function is to increase dissolved oxygen in the water, promote the degradation of pollutants by microorganisms, and drive water circulation. They are characterized by uniform air distribution, high oxygenation efficiency, and relatively compact structure, and are widely used in various biological treatment processes.
[0003] The aeration disc anti-clogging air distribution device is a functional component that is used in conjunction with the aeration disc to prevent the air distribution holes from clogging. It maintains smooth air distribution through structural design or auxiliary functions, and avoids pollutants from clogging the air distribution channel by using membrane opening and closing to isolate impurities, cyclone centrifugal separation of particles, and dynamic cleaning to remove attached substances.
[0004] In existing technologies, some aeration discs suffer from the following problems during installation and fixing due to the traditional aeration disc anti-clogging air distribution device: the existing device is mostly connected to the pipeline by a single thread or snap-fit connection, which is difficult to adapt to pipelines of different diameters. When the pipeline diameter changes, the entire device needs to be replaced, resulting in high adaptation costs and low installation efficiency. This leads to frequent device replacements and significantly increases adaptation costs. Therefore, an aeration disc anti-clogging air distribution device is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an aeration disc anti-clogging air distribution device, which aims to improve the problem of frequent device replacement in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An aeration disc anti-clogging air distribution device includes a chassis. A connecting pipe is fixedly connected to the bottom of the chassis. A connecting ring is fixedly connected to the outside of the connecting pipe. A driven ring is rotatably connected to the left side of the connecting ring. A T-groove is formed inside the driven ring. A linkage ring is rotatably connected to the right side of the connecting ring. A driven plate is rotatably connected to the bottom of the linkage ring. A driven groove is formed inside the driven plate. Two springs are fixedly connected to the top inner wall of the driven groove. A connecting ring is fixedly connected to the bottom of the two springs. An anti-clogging component is rotatably connected to the top of the chassis.
[0008] As a further description of the above technical solution:
[0009] The anti-clogging component includes a rotating ring, with multiple driven blades fixedly connected to the outside of the rotating ring, multiple through holes opened inside the rotating ring, and two cleaning strips rotatably connected to the outside of the rotating ring.
[0010] As a further description of the above technical solution:
[0011] The chassis has multiple air guide grooves inside, and an annular groove inside.
[0012] As a further description of the above technical solution:
[0013] The outer part of the connecting ring is slidably connected to the inside of the driven groove, and the outer part of the connecting ring is in contact with the inner wall of the T-groove;
[0014] As a further description of the above technical solution:
[0015] The top of the chassis is detachably connected to a top plate, and the top plate has multiple ventilation holes inside.
[0016] As a further description of the above technical solution:
[0017] The tops of the two cleaning strips are in contact with the inner wall of the top plate, and the plurality of air guide grooves are distributed in a ring array;
[0018] As a further description of the above technical solution:
[0019] The multiple driven blades are arranged in a ring array, and the connecting pipe is distributed for air circulation through the multiple through holes;
[0020] As a further description of the above technical solution:
[0021] The connecting pipe has threads on its outside, and the bottom of the rotating ring is rotatably connected to the top of the chassis.
[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, the device is screwed and fixed to the pipe interface of the aeration device by the threaded structure on the outside of the connecting pipe. The connecting ring extends outward under the elastic action of the spring, and at the same time, the connecting ring is tightly engaged in the T-groove inside the driven ring, so that the chassis can be stably fixed to the outside of the pipe.

It has strong adaptability and firm connection, simplifies the installation process and improves applicability.
[0024] 2. In this utility model, the airflow impacts the driven blade, causing the rotating ring to rotate continuously. The cleaning strip on its outside rises with the rotation and adheres tightly to the inner wall of the top plate. Through rotational friction, the cleaning strip continuously removes impurities such as sludge and biofilm attached around the aeration holes, thereby achieving automatic removal of impurities from the aeration holes while distributing air, avoiding manual maintenance.

[0031] 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.
[0032] Reference Figure 1 , Figure 3 and Figure 4An embodiment of this utility model provides an aeration disc anti-clogging air distribution device, including a chassis 1. The chassis 1 provides fixation and support for the lower connecting pipe 2. The bottom of the chassis 1 is fixedly connected to the connecting pipe 2, which provides fixation and support for the connecting ring 3. The outside of the connecting pipe 2 is fixedly connected to the connecting ring 3, which provides support for the driven ring 4. The left side of the connecting ring 3 is rotatably connected to the driven ring 4. The driven ring 4 provides space for opening a T-shaped groove 5. The driven ring 4 has a T-shaped groove 5 inside, which is used to connect with the connecting ring 10 to complete the fixation of the device.
[0033] A linkage ring 6 is rotatably connected to the right side of the connecting ring 3. The linkage ring 6 provides support for the driven plate 7 at the bottom. The driven plate 7 is rotatably connected to the bottom of the linkage ring 6. The driven plate 7 provides space for the driven groove 8. The driven groove 8 is opened inside the driven plate 7. The driven groove 8 provides fixation and support for the spring 9. Two springs 9 are fixedly connected to the top inner wall of the driven groove 8. The springs 9 have an elastic function and provide elastic support for their connecting ring 10. The connecting ring 10 is fixedly connected to the bottom of the two springs 9. The connecting ring 10 can be stretched by the elastic function of the springs 9, and can then adapt to different pipe diameters, and fit into the interior of the T-slot 5 to fix the device. An anti-blocking component is rotatably connected to the top of the chassis 1.
[0034] Reference Figure 1 and Figure 2 The anti-clogging component includes a rotating ring 11, which provides fixation and support for the driven blades 12. Multiple driven blades 12 are fixedly connected to the outside of the rotating ring 11. The driven blades 12 can rotate by receiving the direction of the gas blowing, thereby driving the rotating ring 11 to rotate. Multiple through holes 13 are opened inside the rotating ring 11, which can diffuse the gas transmitted through the connecting pipe 2. Two cleaning strips 14 are rotatably connected to the outside of the rotating ring 11. The cleaning strips 14 receive the pressure from the gas, and can rotate and rise to stick to the inner wall of the top plate 17. They receive the force from the rotating ring 11 to rotate and clean. Multiple air guide grooves 15 are opened inside the chassis 1, which can guide and diffuse the gas flowing through the through holes 13, so that the gas is evenly distributed and diffused. An annular groove 16 is opened inside the chassis 1, which can collect and diffuse the gas.
[0035] Reference Figures 2 to 4The connecting ring 10 is externally slidably connected to the inside of the driven groove 8. The driven groove 8 provides limiting and guiding functions for the connecting ring 10. The outside of the connecting ring 10 contacts the inner wall of the T-groove 5. The connecting ring 10 is used to snap into the inner wall of the T-groove 5, which can fix the device to the outside of the pipe. The top of the chassis 1 is detachably connected to the top plate 17. The top plate 17 provides space for the opening of the air diffuser 18. Multiple air diffusers 18 are opened inside the top plate 17. The air diffusers 18 can allow air to pass through, inject oxygen into the aeration tank, and provide a living space for microorganisms. The tops of the two cleaning strips 14 contact the inner wall of the top plate 17. The cleaning strips 14 receive air from the rotating ring 1. The force of 1 rotates to clean the inner wall of the top plate 17. Multiple air guide grooves 15 are arranged in a ring array, which can diffuse and distribute the gas. Multiple driven blades 12 are arranged in a ring array, and the driven blades 12 rotate under the pressure of the gas. The connecting pipe 2 distributes and vents through multiple through holes 13. The gas transmitted by the connecting pipe 2 can be distributed and diffused through the through holes 13, and then guided by the air guide grooves 15. The connecting pipe 2 has threads on the outside and is fixed to the outside of the pipe by the threads. The bottom of the rotating ring 11 is rotatably connected to the top of the base plate 1, and the base plate 1 provides support for the upper rotating ring 11.
[0036] Working principle: During use, the device is screwed and fixed to the pipe interface of the aeration device through the threaded structure on the outside of the connecting pipe 2. Then, by stretching the connecting ring 10, the connecting ring 10 can extend outward through the elastic action of the spring 9, thus adapting to different pipe diameters. The connecting ring 10 is tightly engaged in the T-groove 5 inside the driven ring 4. At the same time, the driven plate 7 at the bottom of the linkage ring 6 forms a limiting guide for the connecting ring 10 through the driven groove 8, so that the chassis 1 can be stably fixed to the outside of the pipe, ensuring that the device and the pipe are firmly connected and the overall fixation is completed.
[0037] When gas is input from the connecting pipe 2, it first enters the air guide groove 15 and annular groove 16 inside the chassis 1 through the through hole 13 on the rotating ring 11. The gas is uniformly diffused through the annular array of air guide grooves 15, and finally released into the water from the diffuser hole 18 of the top plate 17. During this process, the airflow impacts the driven blade 12, driving the rotating ring 11 to rotate continuously. The cleaning strip 14 on its outside rises with the rotation and sticks tightly to the inner wall of the top plate 17. The cleaning strip 14 continuously removes sludge, biofilm and other impurities attached around the diffuser hole 18 through rotational friction. This mechanism of "airflow-driven rotation + dynamic friction cleaning" enables the device to complete the anti-clogging function simultaneously during the air distribution process, ensuring the long-term stable operation of the aeration device.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
