Description

Technical Field

[0001] This invention relates to the field of wastewater purification technology, specifically to a microporous uniform aeration wastewater purification device. Background Technology

[0002] In aerobic biological wastewater treatment processes, aeration devices are one of the core components, primarily functioning to introduce oxygen into the wastewater to meet the metabolic needs of microorganisms. Existing microporous aeration devices typically use ceramic or rubber membranes as the aeration medium, dispersing air into tiny bubbles through micropores to increase the gas-liquid contact area. However, in actual operation, these devices face severe clogging problems. On the one hand, activated sludge flocs in the wastewater easily deposit on the surface of the micropores, especially when the blower stops or air pressure fluctuates, the mixed liquor can easily backflow into the micropores, forming a hard clogging layer after drying. On the other hand, the biofilm formed by microorganisms multiplying on the micropore surface gradually thickens over time, leading to a reduction in the micropore diameter or even complete closure.

[0003] Existing technologies typically employ maintenance methods such as periodic acid washing, high-pressure water backwashing, or mechanical brushing. These methods not only require stopping the normal operation of the aeration device, affecting wastewater treatment efficiency, but are also cumbersome to operate and labor-intensive. Chemical cleaning may also cause secondary pollution to the environment. In addition, existing aerators are often complex in structure and difficult to disassemble during installation and maintenance. Once an aeration unit is damaged, the water tank usually needs to be emptied before replacement, which greatly increases maintenance costs and time costs. Summary of the Invention

[0004] To address the above issues and overcome the shortcomings of existing technologies, this invention provides a microporous uniform aeration wastewater aerobic aeration purification device. By using threaded connections between the branch aeration pipes and the main aeration frame, and in conjunction with a sealed cover, the laying density of the aeration pipes can be flexibly adjusted according to actual treatment needs, achieving modular expansion or reduction of capacity. The aeration components and branch aeration pipes employ a plug-in connection structure, coupled with an internal automatic air circuit design, allowing for replacement of aeration blocks without emptying the water tank; a simple plug-and-play operation is all that's needed. This significantly reduces maintenance difficulty and downtime, ensuring continuous and stable operation of the wastewater treatment device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a microporous uniform aeration wastewater aerobic aeration purification device, comprising a main aeration frame, with main aeration frames mounted on both sides inside the purification tank, and a plurality of branch aeration pipes disposed between the two main aeration frames. Each branch aeration pipe has a connecting sleeve threaded to both ends. Each of the two main aeration frames has a plurality of air guide ports integrally formed on opposite sides, and one end of the connecting sleeve at each end of the branch aeration pipe is threaded to one end of the air guide port on one side of the two main aeration frames. Each branch aeration pipe has a plurality of aeration components movably mounted on its top. Each aeration component includes an aeration block, and the surface of the branch aeration pipe... Several aeration blocks are movable above the aeration tube, and fixed blocks are fixed on both sides of the surface of the aeration tube. Connecting blocks are fixed on both sides of the bottom of the aeration block, and the top of the two fixed blocks is provided with connecting grooves that cooperate with the connecting blocks. A ceramic microporous plate is fixed in the middle of the top of the aeration block, and an air guide tube is fixed in the middle of the interior of the aeration block. The bottom end of the air guide tube extends to the bottom of the aeration block, and several air guide holes are provided on the lower surface of the air guide tube. A pulse groove is provided in the upper part of the interior of the aeration block, and a sealing frame is fixed in the upper part of the surface of the air guide tube. A contraction part is provided in the middle of the air guide tube, and several negative pressure holes are provided on the surface of the contraction part.

[0006] Furthermore, a plurality of pulse plates are slidably arranged inside the pulse groove and on the outer peripheral surface of the closed frame, and a plurality of connecting sleeves are fixedly arranged at the bottom of the pulse plates. A plurality of connecting rods are fixedly arranged at the bottom of the inner wall of the pulse groove, and the top end of each connecting rod is slidably connected to the bottom end of each connecting sleeve. A connecting spring is sleeved on the surface of each connecting rod, and the top end of the connecting spring is connected to the bottom end of the connecting sleeve.

[0007] Furthermore, an air guide pipe is fixedly installed inside the aeration pipe and directly below the air guide tube. A movable cover plate is movably installed at the bottom of the air guide pipe. Several reset slide rods are fixedly installed on the outer side of the top of the movable cover plate. Several reset grooves are fixedly installed on the surface of the air guide pipe. The tops of the several reset slide rods are slidably connected to the interior of the several reset grooves respectively. A reset spring is also sleeved on the surface of each reset slide rod and inside the reset groove. A stop block that cooperates with the reset groove is provided at the top of the reset slide rod.

[0008] Furthermore, the connecting block has limiting holes on both sides, the connecting groove has limiting through grooves on both sides, and the two limiting through grooves have limiting blocks that cooperate with the limiting holes slidingly inside.

[0009] Furthermore, the fixed block is provided with movable grooves on both sides inside, and movable frames are slidably provided inside both movable grooves. An adjusting screw is rotatably provided on one side of the movable frame, and one end of the adjusting screw extends to one side of the fixed block. The surface of the adjusting screw is threadedly connected to the inside of the fixed block.

[0010] Furthermore, an adjusting sleeve is fixedly provided on one side of the limiting block, and a rotating screw is connected to the internal thread of the adjusting sleeve. One end of the rotating screw is rotatably connected to one side of the inner wall of the movable groove, and a drive gear is fixedly provided on one end of the rotating screw. A transmission gear that meshes with the drive gear is also rotatably provided on one side of the inner wall of the movable groove. A drive tooth groove is provided on one side of the movable frame, and the tooth surface of the drive tooth groove meshes with the tooth surface of the transmission gear.

[0011] Furthermore, each negative pressure hole is equipped with an automatic control valve, and the interior of each negative pressure hole is connected to the interior of the pulse groove.

[0012] Furthermore, one end of each air inlet can be threaded with a sealing cap, which is used to seal the air inlet that is not equipped with a separate aeration pipe.

[0013] The beneficial effects achieved by the present invention using the above structure are as follows:

[0014] By using threaded connections between the aeration pipes and the main aeration frame, and with the addition of sealed covers, the laying density of the aeration pipes can be flexibly adjusted according to actual treatment needs, achieving modular expansion or reduction of capacity. The aeration components and the aeration pipes adopt a plug-in connection structure, coupled with an internal automatic air circuit on / off design, so that when replacing aeration blocks, there is no need to empty the water tank; it can be completed with just a simple plug-and-play operation, greatly reducing maintenance difficulty and downtime, and ensuring the continuous and stable operation of the sewage treatment device.

[0015] By incorporating components such as air guide tubes, pulse channels, pulse plates, and connecting springs inside the aeration block, the Venturi effect generated when airflow passes through the contraction section creates negative pressure suction at the negative pressure orifice, driving the pulse plate to compress the spring and draw in air. Subsequently, the negative pressure orifice is closed, and the spring releases potential energy to push the pulse plate upward, instantly compressing the air in the pulse channel to form a high-pressure pulse airflow. Through the periodic process of air intake, compression, and jetting, the micropores are continuously struck, and the resulting high-frequency shock waves and shear forces effectively shake off and blow away biofilm and sludge adhering to the surface and interior of the micropores, achieving online self-cleaning during the aeration process without the need for additional backwashing equipment or chemical agents, thereby extending the service life of the aerator.

[0016] The air guide pipe inside the aeration pipe works in conjunction with the movable cover plate to automatically open the air passage when the aeration block is inserted and automatically close it when it is removed, preventing sewage from flowing back into the main pipeline and avoiding pipeline corrosion and blockage caused by backflow. At the same time, the mechanical locking mechanism between the aeration block and the aeration pipe achieves a stable lock on the aeration block in the underwater environment through the linkage of the adjusting screw, gear rack and pinion and the limit block. Even under strong airflow impact and water flow disturbance, it can ensure that the aeration block will not loosen or fall off, ensuring the long-term stable operation of the aeration purification device.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0029] Example 1

[0030] Please see Figures 1 to 8 As shown, a microporous uniform aeration wastewater aerobic aeration purification device includes: a main aeration frame 1, which is installed on both sides inside the purification tank, and several branch aeration pipes 2 are provided between the two main aeration frames 1. Several aeration components 3 are movably installed on the top of each branch aeration pipe 2; the aeration components 3 are used to perform aeration purification treatment on the inside of the purification tank.

[0031] Furthermore, both ends of the aeration pipe 2 are threaded with connecting sleeves 4, and several air guide ports 6 are integrally formed on the opposite side of the two main aeration frames 1. One end of the connecting sleeves 4 at both ends of the aeration pipe 2 is threaded to one end of the air guide port 6 on one side of the two main aeration frames 1. The connecting sleeves 4 are used to connect the two ends of the aeration pipe 2 and the main aeration frames 1 on both sides, so as to achieve uniform air distribution through the several aeration components 3 set on the top of the aeration pipe 2.

[0032] In addition, each air inlet 6 can also be threaded with a sealing cap 5 at one end. The sealing cap 5 is used to seal the air inlet 6 that is not equipped with the aeration pipe 2. By installing and using the aeration pipe 2 between the two main aeration frames 1, the sealing cap 5 is used to seal the unused end of the air inlet 6.

[0033] Specifically, the aeration component 3 includes aeration blocks 7. Several aeration blocks 7 are movably arranged above the surface of the aeration pipe 2, and fixing blocks 10 are fixedly arranged on both sides of the surface of the aeration pipe 2. Connecting blocks 9 are fixedly arranged on both sides of the bottom of the aeration blocks 7, and the top of the two fixing blocks 10 is provided with connecting grooves 11 that cooperate with the connecting blocks 9. By inserting the connecting blocks 9 on both sides of the bottom of the aeration blocks 7 into the interior of the two fixing blocks 10, the limiting structure inside the two fixing blocks 10 is used to limit the connection of the connecting blocks 9 inside the connecting grooves 11, thereby ensuring the connection stability between the aeration blocks 7 and the aeration pipe 2.

[0034] Furthermore, a ceramic microporous plate 8 is fixedly installed at the center of the top of the aeration block 7, and an air guide tube 28 is fixedly installed in the center of the interior of the aeration block 7; the bottom end of the air guide tube 28 extends to the bottom of the aeration block 7, and several air guide holes 29 are provided on the lower surface of the air guide tube 28; a pulse groove 30 is provided at the upper part of the interior of the aeration block 7, a sealing frame 35 is fixedly installed on the upper surface of the air guide tube 28, a constriction section is provided in the middle of the air guide tube 28, and several negative pressure holes 36 are provided on the surface of the constriction section, with an automatic control device fixed inside each negative pressure hole 36. The valve is controlled, and the interior of each negative pressure hole 36 is connected to the interior of the pulse groove 30; several pulse plates 31 are slidably arranged inside the pulse groove 30 and on the outer peripheral surface of the closed frame 35, and several connecting sleeves 32 are fixedly arranged at the bottom of the pulse plates 31. Several connecting rods 33 are fixedly arranged at the bottom of the inner wall of the pulse groove 30, and the top end of each connecting rod 33 is slidably connected to the bottom end of each connecting sleeve 32. A connecting spring 34 is sleeved on the surface of each connecting rod 33, and the top end of the connecting spring 34 is connected to the bottom end of the connecting sleeve 32.

[0035] It should be noted that after the aeration block 7 is inserted into the surface of the aeration tube 2, the air inside the aeration tube 2 enters the interior of the air guide tube 28 through the air guide hole 29 below the surface of the air guide tube 28. The air flow is accelerated by the contraction section set in the middle of the air guide tube 28. At the same time, the negative pressure generated by several negative pressure holes 36 on the contraction section draws the air inside the pulse groove 30, causing the pulse plate 31 to slide down along the outer surface of the closed frame 35. At this time, the connecting spring 34 on the surface of the connecting rod 33 is in a compressed state. Then, by controlling the automatic control valve inside the negative pressure hole 36 to close, the elastic potential energy of the connecting spring 34 is released, and the pulse plate 31 is pushed to one side of the ceramic microporous plate 8 in an instant. The air on one side of the pulse plate 31 is pushed to one side of the ceramic microporous plate 8, and the micropores inside the ceramic microporous plate 8 are pulsed to perform pulse cleaning operation on the impurities inside the micropores.

[0036] Furthermore, an air guide pipe 23 is fixedly installed inside the aeration pipe 2 and directly below the air guide pipe 28. A movable cover plate 24 is movably installed at the bottom of the air guide pipe 23. Several reset slide rods 25 are fixedly installed on the outer side of the top of the movable cover plate 24. Several reset grooves 27 are fixedly installed on the surface of the air guide pipe 23. The top ends of the several reset slide rods 25 are slidably connected to the interior of the several reset grooves 27. A reset spring 26 is also sleeved on the surface of each reset slide rod 25 and inside the reset groove 27. A stop block that cooperates with the reset groove 27 is provided at the top end of the reset slide rod 25.

[0037] It should be noted that, under normal conditions, the movable cover 24 is driven by the return spring 26 to fit its top against the bottom of the air guide tube 23, and the top of the movable cover 24 is provided with a sealing plug that matches the inside of the air guide tube 23. After the air guide tube 28 at the bottom of the aeration block 7 is inserted into the air guide tube 23, the bottom of the air guide tube 28 is used to push the movable cover 24 downward, so that the air guide tube 23 and the movable cover 24 are separated. The air inside the aeration tube 2 enters the interior of the aeration block 7 through the air guide hole 29 on the surface of the air guide tube 28, and finally the aeration operation is performed through the ceramic microporous plate 8 at the top of the aeration block 7.

[0038] Furthermore, regarding the connection and aeration structure, the device adopts a separate design for the main aeration frame 1 and the branch aeration pipes 2. The two ends of the branch aeration pipes 2 are threadedly connected to the air guide interfaces 6 on the main aeration frame 1 through connecting sleeves 4. Unused interfaces are sealed with sealing caps 5. This design allows for flexible adjustment of the laying density of the branch aeration pipes 2 according to the actual treatment load of the purification tank, realizing modular expansion or reduction. In terms of the connection of the aeration components 3, the aeration blocks 7 are hooked by inserting the bottom connecting blocks 9 into the connecting grooves 11 on the fixing blocks 10. The air guide pipes 23 set inside the branch aeration pipes 2 cooperate with the movable cover plate 24. When the aeration block 7 is inserted, the bottom end of the air guide pipe 28 pushes the movable cover plate 24 to compress the return spring 26 downward, thereby opening the air passage and realizing the automatic opening and closing of the air passage. This ensures that when the aeration blocks 7 are disassembled for maintenance, the sewage in the branch aeration pipes 2 will not backflow into the main network, and also avoids the cumbersome operation of emptying the tank during disassembly.

[0039] When the airflow passes through the constriction section in the middle of the air guide tube 28, the flow velocity increases and the pressure decreases. At this time, the automatic control valve at the negative pressure hole 36 opens, generating negative pressure in the pulse groove 30 using the Venturi effect. This causes the pulse plate 31 to slide downward against the elastic force of the connecting spring 34, increasing the volume of the pulse groove 30 and drawing in air. Subsequently, the control valve closes, the negative pressure disappears, and the connecting spring 34 releases its elastic potential energy, pushing the pulse plate 31 upward instantaneously. This causes the compressed air in the pulse groove 30 to be ejected at high speed through the ceramic microporous plate 8. This periodic process of air intake, compression, and ejection forms a high-frequency pulsed airflow, i.e., the air hammer effect, which can generate strong shear force. This effectively peels off the biofilm and sludge attached to the surface of the ceramic microporous plate 8, preventing micropore blockage and significantly improving aeration efficiency and long-term operational stability.

[0040] Example 2

[0041] Specifically, the connecting block 9 has limiting holes 12 on both sides inside, the connecting groove 11 has limiting through grooves 14 on both sides inside, and the limiting through grooves 14 are slidably provided with limiting blocks 13 that cooperate with the limiting holes 12 inside; the fixing block 10 also has movable grooves 15 on both sides inside, and the movable frame 16 is slidably provided inside the movable grooves 15. One side of the movable frame 16 is rotatably provided with an adjusting screw 17, and one end of the adjusting screw 17 extends to one side of the fixing block 10. The surface of the adjusting screw 17 is threadedly connected to the inside of the fixing block 10.

[0042] Furthermore, an adjusting sleeve 19 is fixedly provided on one side of the limiting block 13, and a rotating screw 18 is threadedly connected inside the adjusting sleeve 19. One end of the rotating screw 18 is rotatably connected to one side of the inner wall of the movable groove 15, and a drive gear 20 is fixedly provided on one end of the rotating screw 18. A transmission gear 21 that meshes with the drive gear 20 is also rotatably provided on one side of the inner wall of the movable groove 15. A drive tooth groove 22 is provided on one side of the movable frame 16, and the tooth surface of the drive tooth groove 22 meshes with the tooth surface of the transmission gear 21.

[0043] It should be noted that after inserting the connecting block 9 into the connecting groove 11, rotating the adjusting screw 17 pushes the movable frame 16 to slide to one side of the movable groove 15, driving the toothed groove 22 to drive the transmission gear 21 to rotate. Then, through the meshing transmission between the transmission gear 21 and the drive gear 20, the rotating screw 18 rotates synchronously. The rotation of the rotating screw 18 controls the adjusting sleeve 19 to move to one side, pushing one side of the limiting block 13 into the limiting hole 12, thereby achieving the limiting lock between the connecting block 9 and the fixing block 10. When replacing the aeration block 7, by releasing the limiting lock between the connecting block 9 and the fixing block 10, the aeration block 7 can be quickly removed from the top of the aeration pipe 2, facilitating the replacement of the aeration block 7.

[0044] Furthermore, after the connecting block 9 is inserted into the connecting groove 11, the operator rotates the adjusting screw 17 located outside the fixed block 10. The rotational motion of the adjusting screw 17 is converted into the linear sliding of the movable frame 16 in the movable groove 15. The drive tooth groove 22 on the side of the movable frame 16 meshes with the transmission gear 21, driving the transmission gear 21 to rotate. In turn, the drive gear 20 is driven to rotate through the meshing transmission. The drive gear 20 drives the rotating screw 18 to rotate. Since the rotating screw 18 is threadedly connected to the adjusting sleeve 19, the rotational motion is again converted into the axial movement of the adjusting sleeve 19, which finally pushes the limiting block 13 through the limiting through groove 14 and precisely engages it in the limiting hole 12 on the connecting block 9.

[0045] The traditional bolt fastening or snap-fit ​​connection is replaced with internal mechanical locking, which can maintain extremely high connection strength under water flow impact and airflow vibration, preventing the aeration block 7 from accidentally falling off. At the same time, the synchronous movement of the internal limit blocks 13 on both sides can be controlled by adjusting the screw 17, simplifying the operation difficulty of underwater installation and replacement of aeration block 7. Maintenance personnel only need a simple rotation to lock or unlock, which greatly reduces operation and maintenance costs and time.

[0046] Example 3

[0047] Specifically, this embodiment discloses a working method for a microporous uniform aeration wastewater aerobic aeration purification device, including the following steps:

[0048] First, determine the number of aeration pipes 2 based on the actual treatment capacity requirements of the wastewater treatment tank. Connect the connecting sleeves 4 at both ends of the aeration pipes 2 to the air inlet 6 on one side of the main aeration frame 1 using threads. Air inlets 6 where no aeration pipes 2 are installed are sealed with caps 5 to construct a complete main air supply network. Next, vertically insert the connecting block 9 at the bottom of the aeration assembly 3 into the connecting groove 11 of the fixing block 10 on the surface of the aeration pipe 2. During this process, the air inlet 28 at the bottom of the aeration block 7 will push downwards against the movable cover 24 at the air inlet 23 inside the aeration pipe 2. The movable cover 24, under pressure, causes the reset slide rod 25 to slide within the reset groove 27 and compress the reset spring 26, thereby causing the air inlet 2... 3. The bottom opening is opened, and the compressed air in the aeration pipe 2 can enter the air guide pipe 28 inside the aeration block 7 through the air guide hole 29 on the surface of the air guide pipe 28. Then, by rotating the adjusting screw 17 on the side of the fixed block 10, the rotation of the adjusting screw 17 drives the movable frame 16 to move horizontally in the movable groove 15. The drive tooth groove 22 on the movable frame 16 drives the transmission gear 21 to rotate. The transmission gear 21 then meshes with the drive gear 20 to rotate. The rotation of the gear drives the rotating screw 18 to rotate. The rotating screw 18 drives the adjusting sleeve 19 to extend outward, thereby pushing the limiting block 13 into the limiting hole 12 inside the connecting block 9, realizing the mechanical rigid locking between the aeration block 7 and the aeration pipe 2.

[0049] After the aeration pipes 2 and the main aeration frame 1 are assembled, the blower is started. Compressed air is delivered to the interior of each aeration block 7 through the main aeration frame 1 and the aeration pipes 2. The airflow first enters the air guide tube 28 and flows through the constriction section in the middle. Due to the narrowing of the constriction section, the airflow velocity increases sharply and the static pressure decreases according to the principle of fluid mechanics. At this time, a significant negative pressure suction is generated at the negative pressure hole 36 on the surface of the constriction section of the air guide tube 28. The controller opens the automatic control valve inside the negative pressure hole 36. The air inside the pulse groove 30 is quickly drawn into the main airflow of the air guide tube 28 through the negative pressure hole 36, resulting in a local vacuum state being formed inside the pulse groove 30 momentarily. Under the action of the pressure difference, the pulse plate 31 located inside the pulse groove 30 overcomes the supporting force of the connecting spring 34 and slides downward along the outer surface of the closed frame 35. The downward movement of the pulse plate 31 causes the connecting sleeve 32 to move downward along the connecting rod 33 and violently compresses the connecting spring 34. At this time, the volume of the pulse groove 30 reaches its maximum state and accumulates the elastic potential energy of the connecting spring 34.

[0050] When the pulse plate 31 moves to the bottom of its stroke or reaches the preset time, the controller quickly closes the automatic control valve inside the negative pressure hole 36, cutting off the airflow channel between the pulse groove 30 and the air guide tube 28, and the negative pressure environment in the pulse groove 30 disappears immediately; at this time, the compressed connecting spring 34 loses its resistance and instantly releases the stored elastic potential energy, and the strong rebound force pushes the connecting sleeve 32 and the pulse plate 31 to rapidly return to their original position along the connecting rod 33; the rapid upward thrust of the pulse plate 31 adiabatically compresses the air in the pulse groove 30 located between the pulse plate 31 and the ceramic microporous plate 8, forming a high-pressure, high-speed pulse airflow; this pulse airflow passes through the micropores of the ceramic microporous plate 8 with extremely high kinetic energy and is ejected outwards, and the high-frequency shock wave and shear force generated can effectively shake off and blow away the biofilm, sludge particles and other blockages attached to the surface and inside the micropores of the ceramic microporous plate 8, thereby realizing the self-cleaning aeration function of the device.
