Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, specifically to aeration equipment for wastewater treatment in environmental engineering. Background Technology

[0002] In the field of environmental engineering, wastewater treatment is a crucial link in maintaining ecological balance and ensuring the sustainable use of water resources. Aeration, as a core component of wastewater treatment technologies such as the activated sludge process, directly impacts wastewater purification effectiveness. The aeration process forces air into the wastewater, transferring oxygen from the air into the wastewater to provide the oxygen needed for aerobic microorganisms to metabolize. Simultaneously, it promotes thorough mixing of wastewater and activated sludge, accelerating pollutant degradation. Therefore, highly efficient and stable aeration equipment is essential for wastewater treatment plants to achieve compliant discharge standards.

[0003] Traditional aeration equipment typically uses fixed-installation aeration pipes, whose angle with the wastewater surface cannot be adjusted according to actual conditions such as wastewater depth and pollutant concentration distribution. When there are differences in water depth or uneven pollutant distribution in different areas of the wastewater tank, fixed-angle aeration devices struggle to ensure a balanced oxygen supply to each area, easily leading to localized over- or under-aeration, which affects microbial activity and pollutant degradation efficiency. Some adjustable-angle aeration equipment uses manual adjustment, which is cumbersome to operate and has low adjustment precision, making it difficult to meet the needs of refined wastewater treatment.

[0004] Therefore, it is essential to provide aeration equipment for wastewater treatment in environmental engineering to solve the above-mentioned technical problems. Utility Model Content

[0005] Based on the above description, this utility model provides an aeration device for wastewater treatment in environmental engineering, which solves the problem that the aeration pipes of existing aeration devices are mostly fixed installations, and the fixed angle aeration device is difficult to ensure a balanced oxygen supply in each area, which easily leads to local over-aeration or under-aeration.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An aeration device for wastewater treatment in environmental engineering includes a support member and an angle adjusting member connected to the support member. A central plate is connected to the angle adjusting member, a rotating member is connected to the central plate, and an aeration member is connected to the rotating member. The angle adjusting member is used to adjust the vertical angle of the aeration member, and the rotating member is used to drive the aeration member to rotate. The aeration member is used to aerate wastewater to purify it.

[0007] Furthermore, the support member includes a base frame and a side frame connected to one side of the base frame.

[0008] Furthermore, the angle adjustment component includes an angle rotating plate rotatably connected to the side frame, and two angle rotating plates are provided, both of which are connected to the middle plate.

[0009] Furthermore, the angle adjustment component includes an electric winding machine connected to the side frame. There are two electric winding machines, and each winding end of the two electric winding machines is connected to a winding rope. The two winding ropes are respectively connected to the angle rotating plate.

[0010] Furthermore, the rotating component includes two rotating motors connected to the central plate.

[0011] Furthermore, the aeration element includes an aeration pipe connected to the rotating end of the rotating motor, and the aeration pipe is connected with a plurality of air outlet holes.

[0012] Furthermore, an air inlet head is connected to the middle plate, the air inlet head is connected to the aeration pipe, and an air supply pipe is connected to the end of the air inlet head away from the aeration pipe.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0014] The angle adjustment component allows for flexible adjustment of the vertical angle of the aeration unit, while the rotating component drives the aeration unit to rotate. Through the synergistic action of these two components, the aeration unit can aerate wastewater from different directions and angles, dispersing air more evenly throughout the wastewater. This increases the contact area and time between wastewater and oxygen, thereby increasing the dissolved oxygen content in the wastewater, promoting the decomposition of organic pollutants by microorganisms, significantly improving the wastewater purification effect, and resulting in more stable and higher-quality treated water. This design addresses the problem that existing aeration equipment often uses fixed-installation aeration pipes, making it difficult to ensure a balanced oxygen supply in different areas and prone to localized over- or under-aeration.

[0031] Example 1:

[0032] Support component 1 serves as the basic load-bearing structure of the equipment, supporting the overall weight of the equipment and ensuring operational stability. The bottom frame 6 is welded from hot-rolled steel plates, forming a rectangular frame structure. Transverse and longitudinal reinforcing ribs are welded inside the frame to enhance its load-bearing capacity. Rubber support pads are bolted to the four corners of the bottom frame 6 to cushion vibrations during operation and increase friction with the ground. The side frame 7 is a vertically mounted rectangular steel frame, welded from steel plates. Its bottom is fully welded to the long edge of one side of the bottom frame 6. Horizontal mounting plates are welded to the top and middle of the side frame 7 for mounting the angle adjustment component 2.

[0033] Angle adjustment component 2 is used to precisely adjust the vertical angle of aeration component 5 to adapt to different sewage tank depths and aeration requirements. Angle rotating plates 8 consist of two symmetrically arranged isosceles trapezoidal steel plates. One side of each plate is hinged to a mounting plate in the middle of the side frame 7. The hinge axis is perpendicular to the side frame 7, ensuring that the angle rotating plates 8 can rotate within a certain range around the hinge axis. The other long sides of the two angle rotating plates 8 are fixedly connected to the two edges of the middle plate 3 by bolts, forming a stable support for the middle plate 3.

[0034] The electric winding machine 9 is a small electric winding machine of model SJ-500.

One end is fixed to the winding wheel of the electric winding machine 9 with a lock, and the other end passes around the guide wheel at the bottom of the side frame 7 and is fixed to the middle of the side of the angle plate 8 away from the hinge with bolts. By synchronously winding or releasing the winding rope 10 by the two electric winding machines 9, the tilt angle of the angle plate 8 can be precisely controlled.

The motors are fixed to the motor mounting holes in the central plate 3 with bolts. The motor's rotating shaft extends vertically downwards, and the shaft end is fixedly connected to the top of the aeration pipe 12 via a flexible coupling. The coupling can buffer the impact force during rotation, ensuring stable transmission.

[0036] The aeration element 5 is the core component for achieving wastewater aeration and purification. The aeration pipe 12 is made of stainless steel, with air outlets 13 evenly distributed on the surface of the pipe. The air outlets 13 are arranged in a spiral pattern to ensure uniform aeration. The top of the aeration pipe 12 is connected to the rotating shaft of the rotating motor 11 via a coupling, and a reinforcing sleeve is fitted in the middle of the pipe to enhance structural strength.

One end is connected to the top side of the aeration pipe 12 via a high-pressure hose, and the other end is connected to the air supply pipe 15 via a thread. The air supply pipe 15 is a PVC reinforced pipe, with one end connected to the air inlet head 14 and the other end connected to an external air source. Valves and flow meters are installed on the pipe to control the air intake.

[0038] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0039] The angle adjustment component allows for flexible adjustment of the vertical angle of the aeration unit, while the rotating component drives the aeration unit to rotate.

This increases the contact area and time between wastewater and oxygen, thereby increasing the dissolved oxygen content in the wastewater, promoting the decomposition of organic pollutants by microorganisms, significantly improving the wastewater purification effect, and resulting in more stable and higher-quality treated water.
