Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a wastewater treatment aeration device. Background Technology

[0002] In wastewater treatment, aeration devices promote the degradation of pollutants by microorganisms through the injection of air into the water. Their core effectiveness relies on the uniformity of gas diffusion and the reliability of the air supply system. Traditional aeration devices generally use fixed aeration pipe networks. An air pump delivers compressed air to the stationary aeration network through static pipes, and then the air bubbles are released through aeration holes or microporous membranes. However, this design has the following technical drawbacks: during long-term operation, the fixed pipe network is prone to uneven bubble distribution in localized areas due to sludge deposition or water disturbance, especially at the bottom or corners of the tank, where anoxic zones can easily form, reducing pollutant degradation efficiency. Utility Model Content

[0003] The present invention provides a wastewater treatment aeration device that can solve the above-mentioned problems.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0005] A wastewater treatment aeration device, comprising:

[0006] Air pump;

[0007] Aeration pipe network;

[0008] An air supply base is provided with an installation through hole and an air inlet channel that is connected at one end to the air pump port of the air pump;

[0009] Gear motor;

[0010] The rotating shaft tube has one end connected to the air inlet of the aeration pipe network, and the other end connected to the motor shaft of the geared motor through a tubular coupling.

[0011] Bearing housing, for mounting the rotating shaft tube;

[0012] The tubular coupling has an annular air inlet groove on its outer tube wall and an air inlet hole located in the air inlet groove and connected to the inside of the coupling.

[0013] The tubular coupling passes through the mounting through hole, and two sealing rings are provided between the outer wall of the coupling and the mounting through hole. The air inlet groove is located between the two sealing rings. The other end of the air inlet channel is connected to the air inlet groove so that the gas output by the air pump is transported to the inside of the tubular coupling through the air inlet channel, the air inlet groove and the air inlet hole, and then enters the aeration pipe network through the rotating shaft tube.

[0014] Preferably, the tubular coupling is connected to both the motor shaft of the geared motor and the rotating shaft tube via a spline structure.

[0015] Preferably, the bearing housing is mounted on a first base, and a second base is mounted on the first base via several pillars. The air pump, air delivery seat, and geared motor are all mounted on the second base.

[0016] Preferably, the outer wall of the tubular coupling and the inner wall of the mounting through hole are provided with axial limiting structures to limit the sealing ring; the axial limiting structure includes annular grooves formed on the outer wall of the coupling and the inner wall of the mounting through hole, and the sealing ring is embedded in the annular groove.

[0017] Preferably, the aeration pipe network includes:

[0018] The air distribution pipe has its air inlet connected to the rotating shaft pipe;

[0019] Several parallel aeration branch pipes are connected to the air outlet of the air distribution pipe through a connecting component.

[0020] Among them, the two outermost aeration branch pipes are connected to both ends of the air distribution pipe through elbow pipes, and the remaining aeration branch pipes are connected to the middle of the air distribution pipe through tee pipes; the connection assembly includes a bolt fastening structure and a sealing element.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1) The aeration pipe network is rotated by the geared motor, which makes the aeration branch pipes form a dynamic diffusion zone in the water. During the rotation, the aeration pipe network stirs the water and releases bubbles evenly, which effectively breaks up the sludge deposits in the anoxic zone at the bottom of the pool, resulting in better uniformity of dissolved oxygen distribution and higher pollutant degradation efficiency.

[0023] 2) The coupling structure of the tubular coupling and the air supply seat is adopted. The annular air inlet groove on the outer wall of the coupling and two sealing rings form a closed air chamber. The gas output by the air pump enters the interior of the coupling directly through the air inlet channel. The double sealing rings block the axial leakage path and significantly improve the gas utilization rate.

[0024] 3) The tubular coupling simultaneously performs power transmission and gas transmission functions, eliminating the need for external rotary joints or independent sealing components, greatly simplifying the equipment structure. Furthermore, the rotary aeration and gas delivery operate synchronously, avoiding pressure fluctuations and energy losses caused by gas path separation.

[0025] 4) The double sealing ring design of the coupling and the mounting through hole, combined with the bearing housing, provides stable support for the rotating shaft tube and can withstand long-term vibration and air pressure impact.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0034] Please refer to Figures 1-4 This embodiment provides a wastewater treatment aeration device, including an air pump 10, an aeration pipe network, an air supply seat 9, a geared motor 11, a rotating shaft tube 5, and a bearing seat 8 for mounting the rotating shaft tube 5. The air supply seat 9 has a mounting through hole 19 and an air inlet channel 17 connected at one end to the air inlet of the air pump 10. One end of the rotating shaft tube 5 is connected to the air inlet of the aeration pipe network, and the other end is connected to the motor shaft of the geared motor 11 via a coupling. The outer wall of the tubular coupling 12 has an annular air inlet groove 14 and an air inlet hole 15 located in the air inlet groove 14 and communicating with the inside of the coupling.

[0035] The tubular coupling 12 passes through the mounting through hole 19, and a sealing ring I 13 and a sealing ring II 16 are provided between the outer wall of the coupling and the mounting through hole 19. The air inlet groove 14 is located between the two sealing rings. The other end of the air inlet channel 17 is connected to the air inlet groove 14 so that the gas output by the air pump 10 is transported to the inside of the coupling through the air inlet channel 17, the air inlet groove 14 and the air inlet hole 15, and then enters the aeration pipe network through the rotating shaft tube 5.

[0036] This device drives the rotating shaft tube 5 to rotate the aeration pipe network via a geared motor 11, while simultaneously integrating a gas channel using a tubular coupling 12. The air inlet channel 17 of the gas delivery seat 9 is connected to the annular air inlet groove 14 on the outer wall of the coupling, forming a dynamic sealing cavity with double sealing rings, achieving zero-leakage gas transmission during rotation.

[0037] In an optional embodiment of this utility model, the tubular coupling 12 is splinedly connected to the shaft of the geared motor 11 and the rotating shaft tube 5, transmitting torque through multiple tooth grooves while allowing slight axial displacement. The multi-tooth contact of the spline disperses stress, avoiding keyway wear or breakage caused by vibration in single-key connections. Axial displacement compensates for installation errors or thermal deformation, thus extending the service life of the coupling.

[0038] In one optional embodiment of this utility model, such as Figure 1 As shown, the bearing housing 8 is installed on the first base 6, and the second base 7 is installed above the first base 6 by several pillars. The air pump 10, the air supply seat 9 and the geared motor 11 are all installed on the second base 7. This layered layout can compress the lateral space occupied and is suitable for long and narrow aeration tanks.

[0039] In one optional embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the outer wall of the tubular coupling 12 and the inner wall of the mounting through hole 19 are provided with axial limiting structures to restrict the sealing ring. The axial limiting structure includes an annular groove 18 formed on the outer wall of the coupling and the inner wall of the mounting through hole 19, and the sealing ring is embedded in the annular groove 18. The groove limiting prevents the sealing ring from being displaced due to air pressure fluctuations or vibrations. The groove depth matches the size of the sealing ring to reduce the initial leakage rate caused by assembly errors.

[0040] In one optional embodiment of this utility model, such as Figure 1 As shown, the aeration pipe network includes:

[0041] Air distribution pipe 3, whose air inlet is connected to rotating shaft pipe 5;

[0042] Several parallel aeration branch pipes 1 are connected to the air outlet of the air distribution pipe 3 through a connecting component.

[0043] Among them, the two outermost aeration branch pipes 1 are connected to both ends of the air distribution pipe 3 through elbow pipe 4, and the remaining aeration branch pipes 1 are connected to the middle of the air distribution pipe 3 through tee pipe 2; the connection components include bolt fastening structure and sealing components.

[0044] In this embodiment, the air distribution pipe 3 and the aeration branch pipe 1 are fastened together by bolts. The middle aeration branch pipe 1 is connected by a tee pipe 2, and the two ends are closed by elbow pipes 4 to form a detachable module. When a single aeration branch pipe 1 is damaged, it can be replaced by removing only some bolts, reducing maintenance time. The aeration area can be flexibly adjusted by increasing or decreasing the number of aeration branch pipes 1 to adapt to different tank sizes.

[0045] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
