Description

Technical Field

[0001] The utility model relates to the field of sewage treatment equipment, and in particular to an anti-clogging sewage pool aeration plate. Background Art

[0002] Aeration discs are auxiliary devices used to provide oxygen for aerobic respiration of aerobic microorganisms during sewage treatment. They are widely used in the chemical, papermaking, and pharmaceutical industries. Aeration discs generally consist of a base with air outlets and a cover with air inlets. An air cavity is formed between the base and cover. During use, air is pumped into the cavity and released through the outlet to achieve aeration. However, in actual use, it has been found that the high number and variety of impurities in sewage can easily clog the air outlets, affecting their proper function and, consequently, the efficiency and quality of sewage treatment. Utility Model Content

[0003] In view of this, the utility model provides a sewage pool aeration plate with an anti-clogging function.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] A blockage-resistant sewage pool aeration plate comprises a base plate and an upper cover, an air cavity is formed between the base plate and the upper cover, the base plate is provided with an air inlet connected to the air cavity, and the upper cover is provided with a plurality of air outlets connected to the air cavity; a mesh plate is movably provided in the air cavity, the lower surface of the mesh plate is provided with a counterweight block that can be used to close the air inlet, the upper surface of the mesh plate is provided with a plurality of top columns, the top columns correspond to the air outlets and are movably inserted in the air outlets, the top columns extend to the outside of the air cavity, and a sealing plug for closing the air outlet is further provided at one end located outside the air cavity.

[0006] In this technical solution, the mesh plate, combined with its counterweight, creates an upward buoyancy force when air is pumped into the air cavity, driving the top post upward and dislodging the sealing plug, thereby opening the air outlet for aeration. During aeration intervals or when air pressure drops, the counterweight causes the mesh plate to descend, resealing the air inlet. During this upward and downward movement, the mesh plate and top post effectively scrape and clear any impurities or sludge that may have accumulated around the air outlet, significantly reducing the risk of decreased aeration efficiency due to blockage and achieving a self-cleaning function.

[0007] Optionally, in a possible implementation, the mesh plate includes a center plate, a ring-shaped frame arranged around the center plate, and ribs arranged in a criss-cross pattern for connecting the center plate and the frame, the counterweight block is arranged on the center plate, and the top column is arranged on the ribs and the center plate.

[0008] In the above technical solution, the mesh plate utilizes a design that combines a center plate, a frame, and crisscrossing ribs. This structure is not only stable but also capable of withstanding high air pressure, reducing the risk of deformation or damage from long-term operation and ensuring the long life and stable operation of the aeration disc. Furthermore, the rib design not only enhances the overall strength of the mesh plate but also guides and disperses airflow, allowing the air entering the air cavity to be more evenly distributed across the various outlets, avoiding localized over- or under-aeration and improving overall aeration efficiency.

[0009] Optionally, in a possible implementation, each connection point of two of the crisscrossing ribs is provided with a top column.

[0010] In the above technical solution, the top column is arranged at the intersection of the ribs. On the one hand, it can more effectively control the flow path of the gas on the mesh plate, ensuring that the gas can be evenly and efficiently distributed to each air outlet, thereby improving the aeration efficiency; on the other hand, the intersection of the ribs is stronger, which can more effectively support the top column and enhance the structural stability of the mesh plate. At the same time, it can also play a certain positioning role, facilitating assembly.

[0011] Optionally, in a possible implementation, a reset assembly is provided on the mesh plate, and the reset assembly includes a limiting column provided on the upper surface of the mesh plate, and an elastic member sleeved on the outer periphery of the limiting column.

[0012] In the above technical solution, the setting of the reset component can realize the automatic reset of the mesh plate, top column and sealing plug. When the aeration disc is working normally, the gas will lift the counterweight block to make the mesh plate rise a certain distance to open the air outlet. When the aeration disc stops working, the elastic part can use its own elastic force and the gravity of the counterweight block to push the mesh plate to quickly return to the preset position, thereby further ensuring that the normal operation of the aeration disc is not affected.

[0013] Optionally, in a possible implementation, there are multiple reset components, and the multiple reset components are all close to the edge of the upper surface of the mesh plate and are evenly spaced apart.

[0014] In this technical solution, since the reset components are evenly distributed along the edges of the stencil, they work together to provide stable support and reset force for the stencil from multiple directions. This layout allows the stencil to maintain a more balanced load state when subjected to various external forces, reducing the risk of deformation or damage caused by excessive force at a single point, thereby significantly enhancing the stability of the overall structure.

[0015] Optionally, in a possible implementation manner, the elastic member is a metal spring or elastic rubber.

[0016] In the above technical solution, both metal springs and elastic rubber have excellent elastic recovery force. After being subjected to external force, they can quickly return to their original shape and size, providing stable and reliable reset force for components such as top columns, ensuring that the aerator disc can maintain stable performance output during long-term use.

[0017] Optionally, in a possible implementation, an air outlet gap is provided between the outer side wall of the top column and the inner side wall of the corresponding air outlet hole.

[0018] In the above technical solution, the presence of the gas outlet gap provides a smooth channel for gas to flow from the inside of the aeration disc to the outside. When the aeration system is activated, the gas can quickly diffuse into the sewage through the gas outlet gap without obstruction, fully mixing with the sewage, improving aeration efficiency and oxygen transfer efficiency, ensuring the continuity and uniformity of gas flow, and helping to improve sewage treatment results.

[0019] Optionally, in a possible implementation, the sealing plug has an inclined side surface, and the sealing plug can be partially inserted into the air outlet.

[0020] In this technical solution, the angled side design allows the sealing plug to fit more closely against the hole wall when inserted into the vent, forming an effective seal. This not only reduces the possibility of gas leakage but also improves the overall efficiency of the aeration system. The design of partially locking into the vent further enhances the stability of the seal, preventing the sealing plug from loosening or falling off due to water flow or gas pressure during the aeration process.

[0021] Optionally, in a possible implementation, a sealing layer is provided at one end of the counterweight block close to the air inlet.

[0022] In the above technical solution, the sealant layer effectively fills the tiny gap between the counterweight and the air inlet, preventing gas leakage during the intake process, thereby effectively improving the overall airtightness of the aeration system. Furthermore, the sealant layer prevents external impurities, such as particulate matter and suspended solids in sewage, from entering the air inlet.

[0023] Optionally, in a possible implementation, the chassis and the upper cover are detachably connected, a card block is provided on the outer edge of the upper cover, and a card slot matching the card block is provided on the outer edge of the chassis, and the card block can be snapped into the card slot.

[0024] In the above technical solution, since the base and cover are detachable, when maintenance, cleaning, or component replacement is required inside the aerator, the two can be easily separated without the need for complicated disassembly tools or procedures. This not only improves maintenance efficiency but also reduces operational difficulty, making maintenance work more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without creative work are within the scope of protection of the present application.

[0033] Please refer to Figure 1 and Figure 2This embodiment provides an anti-clogging sewage pool aeration plate, comprising a base plate 1 and an upper cover 2. An air cavity is formed between the base plate 1 and the upper cover 2. The base plate 1 is provided with an air inlet 11 communicating with the air cavity, and the upper cover 2 is provided with a plurality of air outlets 21 communicating with the air cavity. A mesh plate 3 is movably disposed within the air cavity. A counterweight 4 is provided on the lower surface of the mesh plate 3 for sealing the air inlet 11. A plurality of top posts 5 are provided on the upper surface of the mesh plate 3. The top posts 5 correspond to the air outlets 21 and are movably inserted into the air outlets 21. The top posts 5 extend outside the air cavity and are provided with a sealing plug 6 at one end located outside the air cavity for sealing the air outlets 21. The mesh plate 3 and the top posts 5 are integrally formed, and the sealing plug 6 is detachably connected to the top posts 5.

[0034] In this embodiment, through the arrangement of the mesh plate 3 and its combination with the counterweight 4, when air is pumped into the air cavity to increase the air pressure within the air cavity, the mesh plate 3 is subjected to an upward buoyancy force, which drives the top post 5 to rise and push open the sealing plug 6, thereby opening the air outlet 21 for aeration. During aeration intervals or when the air pressure drops, the counterweight 4 causes the mesh plate 3 to sink to reseal the air inlet 11. During this up and down movement, the mesh plate 3 and the top post 5 can effectively scrape and clean impurities or sludge that may have accumulated around the air outlet 21, thereby significantly reducing the problem of reduced aeration efficiency due to blockage and achieving a self-cleaning function. In addition, the design of the air outlet 21 allows the top post 5 to be directly inserted and controlled to open and close. This ensures that during aeration, gas can quickly and directly enter the sewage through the open air outlet 21, forming uniform microbubbles, increasing the gas-liquid contact area, and improving the oxygen transfer efficiency, thereby accelerating the degradation of organic matter in the sewage.

[0035] Please refer to Figure 3 In this embodiment, the mesh panel 3 comprises a center panel 31, an annular frame 32 surrounding the center panel 31, and crisscrossing ribs 33 connecting the center panel 31 and the frame 32. The counterweight 4 is mounted on the center panel 31, and the top post 5 is mounted on the ribs 33 and the center panel 31. The center panel 31 is a circular plate-like structure, while the frame 32 is an annular plate-like structure. The center panel 31 and the frame 32 are concentric. The outer edge of the frame 32 abuts the inner wall of the air cavity and is movable relative to the inner wall.

[0036] The mesh panel 3 utilizes a design that combines a central panel 31, a frame 32, and crisscrossing ribs 33. This structure is not only stable but also capable of withstanding high air pressure, reducing the risk of deformation or damage from long-term operation, ensuring the long life and stable operation of the aeration disc. Furthermore, the ribs 33 not only enhance the overall strength of the mesh panel 3 but also guide and disperse airflow, allowing the air entering the air cavity to be more evenly distributed to each outlet 21, avoiding localized over- or under-aeration and improving overall aeration efficiency.

[0037] Furthermore, by positioning the top posts 5 on the ribs 33 and center plate 31, the density and position of the top posts 5 can be adjusted to suit varying water quality and aeration requirements. This design provides greater flexibility and adaptability, enabling the aeration disc to be used in a wider range of sewage treatment scenarios.

[0038] In this embodiment, a top post 5 is provided at the junction of two crisscrossing ribs 33. Placing the top post 5 at the intersection of the ribs 33 effectively controls the flow path of gas on the mesh panel 3, ensuring that gas is evenly and efficiently distributed to each air outlet 21, thereby improving aeration efficiency. Furthermore, the intersection of the ribs 33 provides greater strength, effectively supporting the top post 5 and enhancing the structural stability of the mesh panel 3. It also serves as a positioning mechanism, facilitating assembly.

[0039] Please refer to Figure 1 and Figure 4 In this embodiment, a reset assembly 7 is provided on the mesh plate 3. The reset assembly 7 includes a limit post 71 provided on the upper surface of the mesh plate 3 and an elastic member 72 sleeved around the outer periphery of the limit post 71. Specifically, when the aeration disc begins operating and the air inlet 11 begins to expand, the counterweight 4 floats and compresses the elastic member 72, causing the mesh plate 3 to move upward, opening the air inlet 11 and the air outlet 21 to achieve aeration. When the aeration disc stops operating, the elastic member 72 compresses the mesh plate 3 and cooperates with the counterweight 4 to lower the mesh plate 3 to its lowest point, effectively sealing the air inlet 11, thereby resetting the mesh plate 3.

[0040] The setting of the reset component 7 can realize the automatic reset of the mesh plate 3, the top column 5 and the sealing plug 6. When the aeration disc is working normally, the gas will lift the counterweight block 4 to make the mesh plate 3 rise a certain distance to open the air outlet 21. When the aeration disc stops working, the elastic member 72 can use its own elastic force to cooperate with the gravity of the counterweight block 4 to push the mesh plate 3 to quickly return to the preset position, thereby further ensuring that the normal operation of the aeration disc is not affected.

[0041] In this embodiment, multiple reset assemblies 7 are provided, each located near the edge of the upper surface of the screen 3 and evenly spaced. In this embodiment, four reset assemblies 7 are provided, spaced 90 degrees apart on the frame 32. Because the reset assemblies 7 are evenly distributed along the edge of the screen 3, they can work together to provide stable support and reset force for the screen 3 from multiple directions. This layout allows the screen 3 to maintain a more balanced stress state when subjected to various external forces, reducing the risk of deformation or damage caused by excessive stress at a single point, thereby significantly enhancing the stability of the overall structure.

[0042] In this embodiment, the elastic member 72 is a metal spring or elastic rubber. Both metal springs and elastic rubber have excellent elastic recovery force. After being subjected to external forces, they can quickly return to their original shape and size, providing a stable and reliable restoring force for components such as the top column 5, ensuring that the aerator disk can maintain stable performance output during long-term use.

[0043] In this embodiment, there is an air outlet gap between the outer wall of the top column 5 and the inner wall of the corresponding air outlet hole 21. The top column 5 and the air outlet hole 21 are both cylindrical, and the diameter of the top column 5 is smaller than the diameter of the air outlet hole 21.

[0044] Specifically, the presence of the gas outlet gap provides a smooth channel for gas to flow from the inside of the aeration disc to the outside. When the aeration system is activated, the gas can quickly diffuse into the sewage through the gas outlet gap without obstruction, fully mixing with the sewage, improving aeration efficiency and oxygen transfer efficiency, ensuring the continuity and uniformity of gas flow, and helping to improve sewage treatment results.

[0045] In this embodiment, the sealing plug 6 has an inclined side surface, and the sealing plug 6 can be partially inserted into the air outlet 21. The sealing plug 6 is generally in the shape of an inverted truncated cone, with its smaller diameter bottom surface being positioned inside the air outlet 21 and its larger diameter bottom surface being positioned outside the air outlet 21.

[0046] The inclined side design of this embodiment allows the sealing plug 6 to fit more closely against the wall of the vent 21 when inserted, forming an effective seal. This not only reduces the possibility of gas leakage but also improves the overall efficiency of the aeration system. The design of partially inserting into the vent 21 further enhances the stability of the seal, preventing the sealing plug 6 from loosening or falling off due to water flow or gas pressure during the aeration process.

[0047] In this embodiment, a sealant layer 41 is provided on the end of the counterweight 4 closest to the air inlet 11. This sealant layer 41 effectively fills the tiny gap between the counterweight 4 and the air inlet 11, preventing gas leakage during the intake process and thereby effectively improving the overall airtightness of the aeration system. Furthermore, the sealant layer 41 prevents external impurities, such as particulate matter and suspended solids in sewage, from entering the air inlet 11.

[0048] It should be noted that the chassis 1 and upper cover 2 of this embodiment are detachably connected. A latch is provided on the outer edge of the upper cover 2, and a slot is provided on the outer edge of the chassis 1 that matches the latch. The latch engages within the slot. Because the chassis 1 and upper cover 2 are detachable, they can be easily separated when maintenance, cleaning, or component replacement is required within the aerator disc, eliminating the need for complex disassembly tools or procedures. This not only improves maintenance efficiency but also reduces operational difficulty, making maintenance more convenient.
