Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an aeration component for wastewater treatment. Background Technology

[0002] In wastewater treatment processes, aeration is a core step to ensure the efficiency of microbial degradation of pollutants. By introducing gas (mostly air or oxygen) into the wastewater, aerobic microorganisms are provided with the oxygen needed for metabolism, thereby achieving the decomposition and purification of organic pollutants. Therefore, the operational stability and aeration uniformity of aeration components directly determine the overall treatment effect and energy consumption level of the wastewater treatment system. Because wastewater contains a large amount of suspended sludge, fibrous impurities, and microbial flocs, these impurities are easily carried by the water flow and adhere to or accumulate on the inner wall of the air outlet of the aeration component during the aeration process. As the operating time goes by, the air outlet will gradually narrow or even become completely blocked, resulting in increased gas flow resistance and reduced actual aeration area, which in turn leads to a significant decrease in aeration efficiency. If the blockage is not dealt with in time, it may also cause a local "no aeration" phenomenon, causing the microorganisms in that area to become inactive due to lack of oxygen, which seriously affects the wastewater purification effect and may even lead to the treated water quality failing to meet standards. Therefore, an aeration component for wastewater treatment is proposed to address the above problems. Utility Model Content

[0003] The purpose of this invention is to provide an aeration component for wastewater treatment to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: An aeration assembly for wastewater treatment includes a connecting pipe and an aeration box. The top of the aeration box is provided with a cover plate, and the inside of the cover plate is provided with an air outlet. An anti-clogging mechanism and a pushing mechanism are installed inside the aeration box. The anti-clogging mechanism includes a lifting groove, a movable plate is slidably engaged inside the lifting groove, a connecting plate is fixedly connected to the outside of the movable plate, a top column is fixedly connected to the top of the connecting plate, a nylon rod is fixedly connected to the bottom of the movable plate, and a return spring is provided on the outside of the nylon rod. The pushing mechanism includes a rotating shaft, a lever fixedly connected to the outer side of the rotating shaft, and a compression ball fixedly connected to the outer side of the lever.

[0005] As a further optimization of this utility model, the following features are provided: an inlet pipe is fixedly connected to the outside of the connecting pipe, and a motor is fixedly connected to the outside of the aeration box.

[0006] As a further optimization of this utility model, the air outlets are evenly distributed on the inner wall of the cover plate, and the lifting grooves are symmetrically distributed on the inner wall of the aeration box.

[0007] As a further optimization of this utility model, the connecting plate is movably connected to the inside of the aeration box via a movable plate, and the top columns are evenly distributed on the top of the connecting plate.

[0008] As a further optimization of this utility model, the number of top pillars is the same as the number of air outlets, and the top pillars are adapted to the air outlets, with the top pillars located directly below the air outlets.

[0009] As a further optimization of this utility model, the bottom of the nylon rod is movably connected to the inner bottom wall of the lifting groove, the actuating rod and the extrusion ball are evenly distributed on the outside of the rotating shaft, and the extrusion ball is located below the connecting plate.

[0010] As a further optimization of this utility model, the motor is fixedly connected to the outside of the aeration box, and the output end of the motor is fixedly connected to the outside of the rotating shaft.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, when the motor drives the rotating shaft to rotate, the outer component continuously squeezes the connecting plate, causing the top column to accurately extend into the air outlet and push out the sludge and impurities accumulated inside. Subsequently, the reset spring drives the component to reset, forming a cyclic cleaning action, avoiding the decrease in aeration efficiency caused by air outlet blockage. At the same time, the air outlet is evenly distributed and the anti-blockage mechanism ensures smooth flow, allowing the gas to diffuse evenly into the sewage, avoiding local aeration imbalance, providing a stable oxygen supply for sewage treatment, and ensuring continuous and reliable operation.

[0012] 2. In this utility model, the lifting trough provides stable guidance for the lifting of components, avoiding misalignment. The nylon rod is corrosion-resistant and wear-resistant, capable of withstanding external forces and sewage erosion for extended periods, extending component lifespan. The externally mounted motor avoids sewage immersion, reducing the probability of failure. This design not only reduces component wear but also eliminates the need for frequent disassembly and cleaning due to automatic anti-clogging, significantly reducing the frequency and cost of manual maintenance. Furthermore, the stable and uniform aeration effect improves the contact efficiency between sewage and oxygen, optimizes the conditions for microbial degradation of pollutants, helps sewage treatment indicators reach standards faster, and further enhances the overall treatment effect.

[0015] 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.

[0016] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0017] Please see Figures 1-5 This utility model provides a technical solution: An aeration assembly for wastewater treatment includes a connecting pipe 1 and an aeration box 2. The top of the aeration box 2 is provided with a cover plate 3, and an air outlet 31 is opened inside the cover plate 3. An anti-clogging mechanism 5 and a pushing mechanism 6 are installed inside the aeration box 2. The anti-blocking mechanism 5 includes a lifting groove 51, a movable plate 52 is slidably engaged inside the lifting groove 51, a connecting plate 53 is fixedly connected to the outside of the movable plate 52, a top column 54 is fixedly connected to the top of the connecting plate 53, a nylon rod 55 is fixedly connected to the bottom of the movable plate 52, and a return spring 56 is provided on the outside of the nylon rod 55. The pushing mechanism 6 includes a rotating shaft 62, a lever 63 is fixedly connected to the outside of the rotating shaft 62, and a compression ball 64 is fixedly connected to the outside of the lever 63.

[0018] It should be noted that: the air outlets 31 are evenly distributed in the inner wall of the cover plate 3, the lifting grooves 51 are symmetrically distributed in the inner wall of the aeration box 2, the connecting plate 53 is movably connected to the inside of the aeration box 2 through the moving plate 52, the top pillars 54 are evenly distributed on the top of the connecting plate 53, the number of top pillars 54 is the same as the number of air outlets 31, and the top pillars 54 are adapted to the air outlets 31. The top pillars 54 are located directly below the air outlets 31, the bottom of the nylon rod 55 is movably connected to the inner bottom wall of the lifting groove 51, the actuating rod 63 and the extrusion ball 64 are evenly distributed on the outside of the rotating shaft 62, and the extrusion ball 64 is located below the connecting plate 53.

[0019] Furthermore: the connecting pipe 1 serves as the core channel for gas transportation, and its diameter matches the volume of the aeration box 2 to ensure that the gas can enter the box at a suitable pressure. The connection design between the water inlet pipe 4 and the connecting pipe 1 enables gas-liquid mixing and transportation, which facilitates the introduction of sewage for pretreatment and also reduces impurities by flushing the inner wall of the aeration box 2 with water flow. As the core reaction chamber, the aeration box 2 has symmetrically distributed lifting grooves 51 on its inner wall, which not only provide a sliding track for the moving plate 52, but also prevent gas leakage from the gaps in the box by the sealing design of the grooves, ensuring stable gas pressure.

[0020] Specifically: The detachable connection design between the cover plate 3 and the aeration box 2 facilitates regular maintenance of internal components. The air outlet 31 has a tapered structure that is narrow at the top and wide at the bottom. This shape is conducive to the refinement of bubbles and can form a tight fit with the top column 54 to ensure that impurities can be completely pushed out during unclogging. In the anti-clogging mechanism 5, the integrated design of the moving plate 52 and the connecting plate 53 ensures uniform force distribution. The elastic characteristics of the nylon rod 55 and the elastic force parameters of the return spring 56 are matched and calculated to support the weight of the moving plate 52 and quickly drive the top column 54 to return to its original position after the squeeze ball 64 is disengaged, thus avoiding affecting the gas flow.

[0021] As a further implementation of this scheme, an inlet pipe 4 is fixedly connected to the outside of the connecting pipe 1, and a motor 61 is fixedly connected to the outside of the aeration box 2.

[0022] It should be noted that: motor 61 is fixedly connected to the outside of aeration box 2, and the output end of motor 61 is fixedly connected to the outside of rotating shaft 62.

[0023] Furthermore, the rotating shaft 62 of the driving mechanism 6 is made of corrosion-resistant alloy material, and a sealed bearing is provided at the connection with the aeration box 2 to prevent sewage leakage and seepage. The distribution density of the actuating rod 63 and the extrusion ball 64 has been optimized to ensure that the connecting plate 53 can obtain a continuous and uniform upward thrust during the rotation of the rotating shaft 62, avoiding excessive local stress that could cause component deformation. The power of the motor 61 is matched with the load of the rotating shaft 62. Its external installation not only facilitates maintenance, but also isolates it from sewage corrosion through a waterproof shell design, extending its service life.

[0024] Work process: When the aeration component for wastewater treatment is working, the gas is first delivered from an external air source to the aeration box 2 through the connecting pipe 1. At the same time, the wastewater to be treated or backwash water can be introduced through the water inlet pipe 4. After the gas accumulates in the aeration box 2, it is released through the air outlet holes 31 evenly distributed on the inner wall of the cover plate 3 to form bubbles, providing oxygen for microorganisms in the wastewater to degrade pollutants. During the aeration process, the anti-clogging function is activated simultaneously. The motor 61 on the outside of the aeration box 2 drives the rotating shaft 62 in the pushing mechanism 6 to rotate, which in turn drives the actuating rod 63 and the squeezing ball 64 on the outside of the rotating shaft 62 to rotate. When the squeezing ball 64 rotates to the bottom of the connecting plate 53 of the anti-clogging mechanism 5, it will squeeze the connecting plate 53 upward, causing the connecting plate 53 to drive the moving plate 52 to slide upward along the lifting groove 51 symmetrically distributed on the inner wall of the aeration box 2. At this time, the top column 54 on the top of the connecting plate 53, which is the same number as the air outlet 31, is directly opposite and matched, will accurately insert into the air outlet 31 to push out the clogging sludge and impurities. After the squeeze ball 64 rotates with the shaft 62 and disengages from the connecting plate 53, the return spring 56 on the outside of the nylon rod 55 at the bottom of the moving plate 52 releases its elasticity, pushing the moving plate 52 and the connecting plate 53 to reset along the lifting groove 51. The top column 54 exits the air outlet 31 to restore gas flow. The process is repeated under the continuous drive of the motor 61. The nylon rod 55 and the lifting groove 51 ensure the smooth operation of the components, and the external design of the motor 61 reduces sewage erosion, ultimately achieving stable and efficient aeration treatment.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
