Description

Technical Field

[0001] This invention relates to the field of aeration equipment technology, specifically to an aeration device for wastewater treatment in environmental engineering. Background Technology

[0002] In existing wastewater treatment technologies, aeration devices are key equipment for forcibly introducing air into wastewater to provide dissolved oxygen and agitate the liquid. These devices are widely used in aerobic treatment systems of wastewater treatment plants, such as activated sludge processes and MBR (membrane bioreactors), through different aeration methods, such as blower aeration, surface aeration, submersible jet aeration, and submersible aeration. The working principle of aeration equipment includes hydraulic jump, lift, and negative pressure air intake to enhance gas-liquid contact and the oxidative decomposition of organic matter. They are usually composed of blowers, air delivery pipes, and aeration devices, and achieve the aeration effect by forming bubbles of different sizes.

[0003] Existing aeration devices have certain shortcomings in terms of efficiency and aeration range. Medium and large-pore diffusers have low oxygen utilization rates, microporous aeration devices are prone to clogging, and mechanical aerators have high energy consumption and low oxygen utilization rates. These problems lead to uneven aeration effects and limited aeration range, affecting the efficiency and effectiveness of wastewater treatment. Especially under significant changes in influent load, existing aeration devices struggle to achieve dynamic balance, resulting in unstable dissolved oxygen control and impacting the performance of the entire wastewater treatment system. Therefore, existing technologies urgently need improvement to enhance aeration efficiency and expand the aeration range, ensuring the high efficiency and stability of the wastewater treatment process. Summary of the Invention

[0004] This application provides an aeration device for wastewater treatment in environmental engineering, the main purpose of which is to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides an aeration device for wastewater treatment in environmental engineering, comprising: a frame, with edge fixing plates respectively provided at both ends of the frame; an air inlet mechanism, which is disposed at the top of the frame and extends to the inner side of the frame; a plurality of rotating shafts, which are rotatably disposed on the inner side of the frame; a drive motor, which is installed on the inner side of the frame and connected to the end of one of the rotating shafts; a linkage assembly, which is disposed on the plurality of rotating shafts; an aeration assembly, which is configured in multiple units and is respectively installed on the inner side of the frame and extends to the top of the frame; and a pushing assembly, which is configured in multiple sets and is respectively installed on the outer side of the plurality of rotating shafts and the outer wall of the aeration assembly.

[0006] In one feasible implementation, the aeration assembly includes: aeration pipes, a plurality of aeration pipes of varying lengths, each movable in a vertical direction and arranged on a frame with staggered lengths; air outlet pipes, one end of each of the plurality of air outlet pipes being connected to the top end of the plurality of aeration pipes; air outlet holes, a plurality of air outlet holes being respectively opened on the outer side of the outer wall of the plurality of air outlet pipes; and elastic members, a plurality of elastic members being respectively installed on the wall surface of the frame.

[0007] In one feasible implementation, each of the several air outlet pipes has an ejection hole at its end. The ejection hole includes a circular hole, a frustum-shaped hole, and a plurality of diffusion holes. The frustum-shaped hole is located on the innermost side of the air outlet pipe, and the circular hole communicates with the frustum-shaped hole. The plurality of diffusion holes are located on the outermost side of the several air outlet pipes and communicate with the central hole.

[0008] In one feasible implementation, the plurality of elastic components include: a return spring, one end of which is fixedly disposed on the inner wall surface of the frame; and a connecting plate, which is fixedly disposed on the other end of which is respectively, and rotatably connected to the bottom end of which is respectively.

In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. The term "two or more" includes two or more cases.

[0023] according to Figures 1-7 This application provides an aeration device for wastewater treatment in environmental engineering, comprising: a frame 1, an air inlet mechanism, a rotating shaft 2, a drive motor 3, a linkage assembly, an aeration assembly, and a pushing assembly. Edge fixing plates are respectively provided at both ends of the frame 1; the air inlet mechanism is located at the top of the frame 1 and extends to the inner side of the frame 1; several rotating shafts 2 are rotatably arranged on the inner side of the frame 1; the drive motor 3 is installed on the inner side of the frame 1 and connected to the end of one of the rotating shafts 2; the linkage assembly is arranged on several rotating shafts 2; multiple aeration assemblies are provided, each installed on the inner side of the frame 1 and extending to the top of the frame 1; multiple pushing assemblies are provided, each installed on the outer side of the outer wall of the several rotating shafts 2 and the aeration assembly.

[0024] It should be noted that the frame 1 is fixed above the sewage tank by the edge fixing plate. The air intake mechanism is responsible for introducing air and spraying it out from the aeration components. The rotating shaft 2 is connected to the drive motor 3, which provides the rotational power. The linkage component ensures that the rotating shaft 2 can work in tandem. Multiple aeration components are set up, increasing the aeration area. When the drive motor 3 starts, the rotating shaft 2 begins to rotate through the linkage component, thus driving the components to work, propelling the aeration components to move back and forth vertically while performing aeration. Because the aeration pipes 4 in the aeration components are designed with alternating long and short lengths, this allows for a more effective increase in aeration area during the aeration process, thereby improving the aeration effect.

[0025] In some examples, the aeration assembly includes: aeration pipe 4, air outlet pipe 5, air outlet 6, and elastic element 7. Several aeration pipes 4 are of different lengths and are respectively movable in the vertical direction on the frame 1, and are distributed in an alternating manner; one end of several air outlet pipes 5 is respectively connected to the top end of several aeration pipes 4; several air outlets 6 are respectively opened on the outer side of the outer wall of several air outlet pipes 5; several elastic elements 7 are respectively installed on the wall surface of the frame 1.

[0026] It should be noted that the aeration pipes 4 are of varying lengths and are staggered to increase the aeration area. The air outlet pipe 5 connects to the air inlet assembly. The air outlet 6 releases gas for aeration. The elastic element 7 ensures that the aeration pipe 4 returns to its original position after being pushed out by the pushing assembly. During operation, the pushing assembly pushes the aeration pipe 4 out, causing it to move vertically, while the elastic element 7 ensures that the aeration pipe 4 returns to its original position after movement. When the aeration pipe 4 is pushed out, the air outlet pipe 5 releases gas through the air outlet 6 for aeration. The resetting function of the elastic element 7 allows the aeration pipe 4 to return to its starting position after each push, and then be pushed out again by the pushing assembly, achieving reciprocating movement and air jetting, thus effectively performing aeration operations in wastewater treatment.

[0027] In some examples, each of the ends of several air outlet pipes 5 is provided with a spray hole 8. The spray hole 8 includes: a circular hole 81, a frustum-shaped hole 82 and a plurality of diffuser holes 83. The frustum-shaped hole 82 is located on the innermost side of the air outlet pipe 5. The circular hole 81 is connected to the frustum-shaped hole 82. The plurality of diffuser holes 83 are located on the outermost side of the several air outlet pipes 5 and are connected to the central hole.

[0028] It should be noted that during aeration, the frustum-shaped orifice 82 is located at the innermost side of the outlet pipe 5, and its function is to accelerate the airflow and increase the gas passage speed. The circular orifice 81 is connected to the frustum-shaped orifice 82 and is used to guide the airflow from the frustum-shaped orifice 82 to the outside. The gas is further diffused through multiple diffuser holes 83 to achieve a wider aeration effect. During the reciprocating motion of the aeration pipe 4, the airflow accelerated by the frustum-shaped orifice 82 flows through the circular orifice 81 to the diffuser holes 83, so that not only the outer part of the outer wall of the outlet pipe 5, but also the edge part at the end can be effectively aerated. Through the acceleration effect of the frustum-shaped orifice 82 and the diffusion effect of the diffuser holes 83, the gas can be evenly distributed along the entire length of the aeration pipe 4, achieving a comprehensive aeration effect and improving the oxygen transfer efficiency and aeration uniformity in the sewage treatment process.

[0029] In some examples, the plurality of elastic components 7 include: a return spring 71 and a connecting plate 72. One end of the plurality of return springs 71 is fixedly disposed on the inner wall surface of the frame 1; the plurality of connecting plates 72 are fixedly disposed on the other end of the plurality of return springs 71 and are rotatably connected to the bottom end of the plurality of aeration pipes 4.

[0030] It should be noted that the function of the return spring 71 is to reset the aeration pipe 4 after it is pushed out by the pushing assembly, using the elastic force of the spring. Through the action of the return spring 71 and the connecting plate 72, the aeration pipe 4 can quickly return to its initial position after one push, ready for the next push. This ensures that the aeration pipe 4 can perform efficient and continuous aeration operation. At the same time, the coordinated use of the return spring 71 and the connecting plate 72 guarantees the stable operation of the aeration pipe 4, improving the overall efficiency and aeration effect of the aeration device.

[0031] In some examples, the actuating components include: eccentric gears 9, rotating disks 10, and meshing pins 11. Several eccentric gears 9 are respectively installed on the outer side of the outer wall of several rotating shafts 2 in an alternating manner; several rotating disks 10 are respectively installed at the bottom end of several aeration pipes 4; one end of several meshing pins 11 is respectively installed on the surface of several rotating disks 10 and respectively meshes with the teeth on several eccentric gears 9.

[0032] It should be noted that the eccentric gears 9 are installed alternately on the outer side of the outer wall of the rotating shaft 2. When the drive motor 3 starts and drives the rotating shaft 2 to rotate, the eccentric gears 9 also rotate. Due to the eccentric setting of the eccentric gears 9, a pushing force is applied to the rotating disk 10 installed at the bottom of the aeration pipe 4, causing the rotating disk 10 to reciprocate in the vertical direction. At the same time, the meshing pins 11 on the surface of the rotating disk 10 mesh with the teeth on the eccentric gears 9. The meshing action not only pushes the rotating disk 10 to move up and down, but also causes the rotating disk 10 and the aeration pipe 4 to rotate together. This allows the aeration pipe 4 to rotate while moving vertically, increasing the dynamic effect of the aeration area, expanding the aeration range, and thus improving the aeration effect and the airflow transfer efficiency in the wastewater.

[0033] In some examples, the air intake mechanism includes: an aerator 12, an air intake manifold 13, a connecting pipe 14, and a telescopic pipe 15. The aerator 12 is mounted on the top surface of the frame 1. One end of the air intake manifold 13 is connected to the air outlet of the aerator 12. Several connecting pipes 14 have several branches, and the several branches are respectively connected to the bottom ends of several aeration pipes 4. One end of several telescopic pipes 15 is connected to one end of several connecting pipes 14, and the other end is connected to several air intake manifolds 13.

[0034] It should be noted that the aerator 12 is mounted on the top surface of the frame 1 and is responsible for compressing and preparing air for delivery. The main air inlet pipe 13 is used to deliver compressed air from the aerator 12 to the connecting pipe 14. Each branch of the connecting pipe 14 is directly connected to the bottom end of the aeration pipe 4, ensuring that air can be distributed to each aeration pipe 4. The telescopic pipe 15 allows the connecting pipe 14 to extend or retract when the aeration pipe 4 needs to move, to accommodate the reciprocating motion of the aeration pipe 4 and ensure the continuity and stability of the air supply. When the aerator 12 is working, compressed air passes through the main air inlet pipe 13, the branches of the connecting pipe 14, and the telescopic pipe 15, finally reaching the aeration pipe 4 to complete the air delivery and distribution, thereby realizing the aeration operation in the sewage treatment process.

[0035] In some examples, the linkage components include: sprockets 16 and chains 17, with several sprockets 16 respectively mounted on the outer side of the outer wall of several rotating shafts 2; and several chains 17 respectively mounted on several sprockets 16.

[0036] It should be noted that the sprocket 16 and chain 17 form a closed chain drive system. When the drive motor 3 starts and drives one of the rotating shafts 2 to rotate, the sprocket 16 connected to it also rotates. Through the transmission of the chain 17, this rotational motion is synchronized to all other sprockets 16. Since the chain 17 connects all the sprockets 16, it ensures that all rotating shafts 2 can rotate in a coordinated manner, thereby enabling the aeration components to work in a predetermined synchronous manner. This not only achieves power transmission but also ensures the synchronicity between the rotating shafts 2, which is crucial for the uniform aeration and efficient operation of the aeration device.

[0037] The above are merely embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
