Description

Technical Field

[0001] This utility model relates to the technical field of sewage treatment equipment, specifically to a submerged aeration bed. Background Technology

[0002] In wastewater treatment processes, aeration beds are core equipment, and their performance directly affects the dissolved oxygen content and pollutant degradation efficiency in water.

[0003] Currently, traditional aeration beds generally adopt a fixed installation mode. Once the equipment malfunctions, the sewage tank must be emptied before repairs can be carried out. This process not only consumes a lot of manpower and material resources, but also has a long repair cycle, which will cause the sewage treatment process to be interrupted and significantly reduce treatment efficiency.

[0004] Some mobile aeration equipment uses complex mechanical lifting structures or external buoyancy adjustment devices, which not only results in bulky and large equipment structures, but also significantly increases energy consumption and makes daily maintenance and operation cumbersome and costly.

[0005] In addition, existing aeration beds have structural design flaws, with the aeration supply system and the regulation system being independent of each other, failing to achieve deep integration of structure and function, which seriously restricts the improvement of the overall performance of the equipment.

[0006] Therefore, developing a submerged aeration bed with a compact structure, integrated functions, and convenient operation and maintenance has become an urgent technical challenge in the field of wastewater treatment. Summary of the Invention

[0007] In view of the above technical problems, this utility model provides a submersible aeration bed to solve the above technical problems.

[0008] A submersible aeration bed includes a buoyancy adjustment frame, an aeration main pipe, and aeration pipes. The buoyancy adjustment frame has a hollow structure and is connected to an external air source and water source to change the state of the internal medium. The aeration main pipe is installed on the buoyancy adjustment frame and is connected to the external air source. One end of several aeration pipes is connected to the aeration main pipe, and the other end is installed on the buoyancy adjustment frame.

[0009] Furthermore, the buoyancy adjustment frame includes interleaved adjustment supports and adjustment pipes. The adjustment support includes a frame tube, with an adjustment pipe connected to each end of the frame tube by flanges. A main pipe flange is provided on the frame tube, and the aeration main pipe is installed on the main pipe flange. A pipe distribution flange is provided on the frame tube, and an exhaust pipe and a drain pipe connected to an external air source and water source are introduced into the pipe distribution flange.

[0010] Furthermore, the aeration main pipe is provided with a connection hole, which matches the aeration pipe. The aeration pipe includes a mounting base, a pipe body, and a clamp. The mounting base is installed on the aeration main pipe, and the clamp is installed on the regulating pipe. The clamp is provided with a drain hole and an exhaust hole that match and communicate with the regulating pipe. The pipe body is disposed between the mounting base and the clamp.

[0011] Furthermore, one end of the clamp is a clamp-shaped structure, and the other end is an internally threaded cylindrical structure. An adjusting relief member is connected inside the internally threaded cylindrical structure of the clamp, and the tube body abuts against the protrusion of the adjusting relief member.

[0012] Furthermore, the clamp is provided with locking screws for fixing the installation position of the adjustment and relief component.

[0013] Furthermore, both the regulating pipe and the aeration main pipe are connected by several short pipes. A reinforcing beam is provided at the connection of the short pipes. The reinforcing beam has frame mounting holes and main pipe mounting holes for connecting the regulating pipe short pipe and the aeration main pipe short pipe.

[0014] The beneficial effects of this utility model are as follows:

[0015] Significantly improves maintenance convenience and efficiency: Through the cavity structure of the buoyancy adjustment frame and its connection to external air / water sources, the entire equipment can be floated or submerged simply by adjusting the medium inside the cavity (air filling or water injection). This mechanism completely avoids the cumbersome process of emptying the sewage tank during traditional aeration bed maintenance, greatly shortens the maintenance cycle, reduces manpower and material consumption, and ensures the continuity of the sewage treatment process.

[0016] Functional integration: The buoyancy adjustment frame simultaneously undertakes the dual functions of aeration support and buoyancy adjustment, solving the structural defects of the separation of aeration system and adjustment system in traditional equipment, realizing deep functional integration and reducing redundant structure.

[0017] Modular design: The regulating bracket, regulating pipe and aeration main pipe are connected by flanges, and the short pipe splicing nodes are reinforced by reinforcing beams, which not only improves the overall structural stability, but also facilitates transportation, quick assembly and partial replacement, and reduces operation and maintenance costs.

[0018] Pipeline consolidation: Vent and drain pipes are centrally introduced through piping flanges, optimizing the pipeline layout and avoiding clutter.

[0019] Efficient maintenance and reliable operation of the aeration pipe: The aeration pipe adopts a threaded design with clamps and adjusting relief parts, allowing for quick disassembly of the pipe body by rotation, significantly simplifying maintenance operations. Locking screws further secure the position of the adjusting relief parts, ensuring tension stability under aeration vibration.

[0020] Three-dimensional aeration network: The elevated design of the main aeration pipe, combined with the distributed layout of multiple aeration pipes, expands the coverage area for bubble release. Adding stirring aeration pipes disturbs the sediment below the main aeration pipe, reducing dead zones and improving dissolved oxygen uniformity and pollutant degradation efficiency.

[0021] Energy saving and intelligent operation: It abandons complex mechanical lifting or external buoyancy devices, relying on medium state switching to achieve lifting, resulting in a compact structure and significantly reduced energy consumption. Combined with a control system, it precisely regulates water injection / aeration, aeration start / stop, and drainage valve operation, improving automation and reducing manual intervention.

[0022] In summary, this utility model, through its integrated structural-functional design, not only ensures efficient aeration performance but also completely solves the pain points of traditional equipment, such as difficult maintenance, bulky structure, and high energy consumption, achieving a compact, intelligent, and low-cost upgrade of core wastewater treatment equipment.

[0029] Example 1: To address the problem of cumbersome and costly daily maintenance of aeration beds, this example provides a submerged aeration bed.

[0030] like Figure 1As shown, the submerged aeration bed includes a buoyancy adjustment frame 1, an aeration main pipe 2, and aeration pipes 3. The buoyancy adjustment frame 1 has a hollow structure and is connected to an external air source and water source to change the state of the internal medium. The aeration main pipe 2 is installed on the buoyancy adjustment frame 1 and is connected to an external air source. One end of several aeration pipes 3 is connected to the aeration main pipe 2, and the other end is installed on the buoyancy adjustment frame 1.

[0031] The buoyancy adjustment frame 1 provided in this embodiment simultaneously serves as aeration support and buoyancy adjustment, simplifying the structure and reducing energy consumption. For convenient maintenance, the entire equipment can be floated or submerged by changing the medium inside the cavity (air filling / water injection), allowing for repairs without emptying the water tank.

[0032] like Figure 2 and Figure 3 As shown, the buoyancy adjustment frame 1 includes an adjustment bracket 11 and an adjustment pipe 12 connected in an alternating manner. The adjustment bracket 11 includes a frame pipe 14, with an adjustment pipe 12 connected to each end of the frame pipe 14 by flanges. A main pipe flange 15 is provided on the frame pipe 14, and the aeration main pipe 2 is installed on the main pipe flange 15. A pipe distribution flange 13 is provided on the frame pipe 14, and an exhaust pipe 16 and a drain pipe 17 connected to the external air source and water source, respectively, are introduced into the pipe distribution flange 13.

[0033] The buoyancy adjustment frame 1 adopts a modular design, facilitating quick assembly and disassembly via flange connections, reducing transportation and assembly costs. Pipeline integration is achieved using the piping flange 13, with air / water supply pipelines centrally connected to 13, avoiding cluttered wiring. During assembly, the regulating pipe 12 is flanged to the frame pipe 14; an external air source (blower) is connected via the piping flange 13 to achieve aeration of the wastewater tank; the exhaust pipe 16 and drain pipe 17 within the piping flange 13 control the water injection and aeration media.

[0034] like Figure 4 As shown, the aeration main pipe 2 has a connection hole that matches the aeration pipe 3. The aeration pipe 3 includes a mounting base 31, a pipe body 32, and a clamping component 34. The mounting base 31 is installed on the aeration main pipe 2, and the clamping component 34 is installed on the regulating pipe 12. The clamping component 34 has a drain hole 36 and a vent hole 37 that are connected to and match the regulating pipe 12. (The function of the drain hole 36 and the vent hole 37 is that when sinking, the buoyancy regulating frame 1 is filled with water. When the water level reaches the drain hole 36, the water enters the inner cavity of the pipe body 32, and the gas in the inner cavity of the pipe body 32 is discharged through the vent hole 37. The inner cavity of the pipe body 32 is filled with water, increasing the weight. Conversely, when floating, the buoyancy regulating frame 1 is inflated with air. When the water level drops to the vent hole 37, the air enters the inner cavity of the pipe body 32, and the water in the inner cavity of the pipe body 32 is discharged through the drain hole 36. The inner cavity of the pipe body 32 is filled with air, increasing the buoyancy.) The pipe body 32 is located between the mounting base 31 and the clamping component 34.

[0035] An aeration membrane is installed on the pipe body 32. Gas overflowing from the vents of the pipe body 32 passes through the aeration membrane and is released into the wastewater in the form of tiny bubbles, continuously aerating the wastewater and providing sufficient oxygen for microorganisms to promote pollutant degradation. The clamp 34 and the mounting base 31 anchor the aeration pipe to the regulating pipe to prevent displacement due to water flow impact.

[0036] Specifically, one end of the clamp 34 has a clamp-like structure, and the other end has an internally threaded cylindrical structure. An adjusting relief member 33 is connected inside the internally threaded cylindrical structure of the clamp 34, and the pipe body 32 abuts against the protrusion of the adjusting relief member 33. During maintenance, the pipe body 32 can be quickly disassembled by rotating the adjusting relief member 33 and screwing it into the internally threaded cylindrical structure of the clamp 34.

[0037] Specifically, the clamp 34 is equipped with a locking screw 35, which is used to fix the installation position of the adjusting relief component 33. The locking screw 35 can ensure that the tensioning effect of the adjusting relief component 33 on the pipe body 32 is stable and not affected by aeration vibration.

[0038] like Figure 1 and Figure 2 As shown, both the regulating pipe 12 and the aeration main pipe 2 are connected by several short pipes. A reinforcing beam 4 is provided at the connection of the short pipes. The reinforcing beam 4 has frame mounting holes 41 and main pipe mounting holes 42 for connecting the short pipes of the regulating pipe 12 and the short pipes of the aeration main pipe 2. In addition to reinforcing the connection of the short pipes, the reinforcing beam 4 also provides support, allowing the aeration main pipe 2 to be raised and its operating range to be wider.

[0039] To minimize blind spots in the operation, a stirring and aeration pipe 18 connected to the air source is also installed on the frame pipe 14 to turbulent the sediment below the aeration main pipe 2.

[0040] As shown in the figure: 1. Buoyancy adjustment frame; 11. Adjustment bracket; 12. Adjustment pipe; 13. Pipe flange; 14. Frame pipe; 15. Main pipe flange; 16. Exhaust pipe; 17. Drainage pipe; 18. Mixing and aeration pipe; 2. Aeration main pipe; 3. Aeration pipe; 31. Mounting base; 32. Pipe body; 33. Adjustment clearance component; 34. Hoop component; 35. Locking screw; 36.

[0041] In actual use, it includes the following three processes:

[0042] Descent process: The operator and maintenance personnel use the control system to allow water from the external water source to flow into the buoyancy adjustment frame 1 through the drain pipe 17. The gas inside the chamber is discharged through the exhaust pipe 16. As the water level inside the chamber rises, the weight of the aeration bed gradually increases. Under the action of gravity, the aeration bed slowly sinks to the predetermined working position in the sewage tank.

[0043] Aeration process: After the aeration bed sinks to the predetermined position, the aeration blower is started through the control system, and the valve on the main aeration pipe is opened. Air enters the aeration pipe 3 through the main aeration pipe 2, and is finally released into the sewage in the form of tiny bubbles by the aeration membrane, continuously carrying out aeration work to provide sufficient oxygen for the microorganisms in the sewage and promote the degradation of pollutants.

[0044] Ascent Process: When maintenance of the aeration bed is required, the maintenance operator first closes the main aeration valve through the control system to stop aeration. Then, the air pump is started, and high-pressure gas is injected into the buoyancy adjustment chamber through the exhaust pipe 16. The gas compresses the water in the chamber, and the water is discharged through the drain pipe 17. As the water level in the chamber gradually decreases, the weight of the aeration bed decreases, and it gradually rises under the action of buoyancy. Once the aeration bed rises to the water surface and stabilizes, the air pump and drain valve are closed. At this time, the maintenance personnel can directly disassemble and replace worn aeration pipes and other components on the water surface. After the maintenance work is completed, the aeration bed can be lowered back to the working position by injecting water to restore normal operation.
