Description

Technical Field

[0001] This utility model relates to the field of aeration device technology, and in particular to an anti-clogging aeration device for MBR membrane modules for high-salt industrial wastewater. Background Technology

[0002] MBR technology is widely used in the treatment of high-salinity wastewater due to its combination of efficient solid-liquid separation and biodegradation. Its core principle is to use MBR membrane modules to retain microorganisms in activated sludge, extend the sludge age, and improve the degradation efficiency of pollutants. The aeration device, as an important component of the MBR system, plays a dual role in supplying oxygen to the reaction tank, maintaining microbial activity, and mitigating membrane module fouling through airflow disturbance.

[0003] To address this, patent CN215249836U discloses an MBR membrane aeration device, fixedly installed inside an MBR tank. It includes a blower, a main gas supply pipe, and multiple branch gas supply pipes. The inlet end of the main gas supply pipe is connected to the blower, and the outlet end is connected to the multiple branch gas supply pipes. The branch gas supply pipes are hollow cylinders, arranged vertically side-by-side inside the MBR tank. Multiple aeration holes are opened on the side facing the inside of the MBR tank, and aeration plates are fixedly connected to them. The two sides of the aeration plates are fixedly installed inside the MBR tank, and multiple through holes are evenly distributed on them. The MBR membrane aeration device disclosed in this utility model, after the first aeration through the aeration branch pipes, allows the aeration plates to gather the air bubbles into larger bubbles, resulting in a stronger scouring force on the MBR membrane fibers and less surface fouling. Simultaneously, the aeration plates also prevent backflow of wastewater, avoiding blockage of the aeration holes and reducing maintenance costs.

[0004] The MBR membrane aeration device mentioned above only achieves "passive anti-clogging" by blocking sewage backflow through aeration plates during use, which can only address the problem of pollutant adhesion on the surface of aeration holes. However, in the treatment of high-salt wastewater, salt crystallization will simultaneously form scale on the surface of membrane modules and the inner wall of aeration pipes, and rely on large air bubbles to flush the surface of membrane fibers. Simple airflow flushing cannot destroy the attached crystals, making cleaning inconvenient. Utility Model Content

[0005] The purpose of this invention is to provide an anti-clogging aeration device for MBR membrane modules used in high-salt industrial wastewater treatment, in order to solve the problem that existing MBR membrane aeration devices are not easy to clean.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an anti-clogging aeration device for MBR membrane modules of high-salt industrial wastewater, including a mounting plate;

[0007] A bottom pipe is installed at the top of the mounting plate, and an air pump is installed on one side of the top of the bottom pipe. An air delivery pipe is fixed to the output end of the air pump. A cleaning structure is installed inside the bottom pipe. The cleaning structure includes a connecting pipe fixed to the inside of the bottom pipe. A threaded groove is provided inside the connecting pipe. An aeration pipe is installed between the connecting pipes. An aeration hole is fixed to the top side of the aeration pipe. An internal thread is provided inside the aeration hole. An aeration disc is installed at the top of the aeration hole. An installation pipe is fixed to the bottom end of the aeration disc inside the internal thread. An installation groove is provided at the top of the aeration disc. An installation frame is installed inside the installation groove. A filter screen is fixed inside the installation frame.

[0008] The bottom end of the bottom tube is fixed with a hammering structure.

[0009] Preferably, the bottom pipe is rectangular, the gas supply pipe is a four-way pipe, the bottom end of the gas supply pipe is fixedly connected to the top side of the bottom pipe, and the gas supply pipe is connected to the interior of the bottom pipe.

[0010] Preferably, a bracket is fixed inside the aeration disc, a first rotating shaft is installed inside the bracket, a fixing sleeve is fixed to the bottom side of the aeration pipe at the bottom end of the first rotating shaft, a first rotating plate is fixed to both sides of the first rotating shaft inside the aeration pipe, a brush plate is installed on one side of the first rotating shaft at the top of the filter screen, a locking block is fixed to one end of the brush plate, and a locking groove is provided on one side of the first rotating shaft outside the locking block.

[0011] Preferably, the connecting pipes are distributed at equal intervals on both sides of the inner side of the bottom pipe, and the two ends of the aeration pipe are threadedly connected to the connecting pipes through threaded grooves. The interior of the aeration pipe is connected to the interior of the bottom pipe.

[0012] With the above structure, the threaded connection facilitates quick assembly and disassembly during use. When the aeration pipe malfunctions or becomes blocked, it can be disassembled and repaired separately, reducing the difficulty of operation and maintenance.

[0013] Preferably, the aeration holes are evenly distributed on the top side of the aeration pipe, the mounting pipe and the aeration holes are connected by internal threads, the mounting frame and the aeration disc are connected by mounting grooves, the interior of the aeration disc is connected to the interior of the aeration pipe, and a mounting hole is provided in the middle position inside the filter screen.

[0014] With the above structure, the airflow can be evenly delivered to the aeration disc through the aeration holes evenly distributed on the top side of the aeration pipe during use. Then, it diffuses through the filter screen holes, ensuring uniform aeration around the MBR membrane module, improving oxygen transfer efficiency, and providing sufficient oxygen for microbial degradation of pollutants. The installation pipe and aeration holes, as well as the installation frame and aeration disc, are all connected by threads, which facilitates quick disassembly and assembly. When a component is damaged or blocked, it can be replaced and maintained individually, reducing the difficulty and cost of operation and maintenance.

[0015] Preferably, the first rotating shaft is rotatably connected inside the bracket, and limit blocks are fixed on the outer sides of the first rotating shaft at both ends of the bracket, and the bottom end of the first rotating shaft is rotatably connected inside the fixed sleeve.

[0016] With the above structure, the limiting blocks on the outer side of the first rotating shaft at both ends of the bracket can limit the axial displacement of the first rotating shaft during rotation, avoiding misalignment of the brush plate and filter screen due to shaft offset, which would affect cleaning efficiency. The bottom end of the first rotating shaft is rotatably connected inside the fixed sleeve, which further enhances the rotational stability of the shaft and reduces shaft shaking.

[0017] Preferably, the first rotating plates are symmetrically distributed on both sides of the first rotating shaft inside the aeration pipe, the first rotating plates are semi-circular, the bottom end of the brush plate abuts against the top end of the filter screen, and the locking block and the locking groove are engaged.

[0018] With the above structure, during use, the first rotating plate is symmetrically and semi-circularly distributed on both sides of the first rotating shaft, which can more evenly receive the thrust of the airflow in the aeration pipe, drive the rotating shaft to rotate stably, and ensure that the brush plate wipes the filter screen synchronously and evenly. The locking block and the locking slot are connected, which not only facilitates the quick installation and replacement of the brush plate and reduces the difficulty of operation and maintenance, but also fixes the position of the brush plate to prevent it from shifting during wiping and ensures stable cleaning effect.

[0019] Preferably, the striking structure includes a fixed cylinder fixed to the top of the mounting plate, a sliding rod installed inside the fixed cylinder, a limit plate fixed to the outer side of the top of the fixed cylinder, a spring installed on the outer side of the sliding rod at the top of the limit plate, a second rotating shaft installed on both sides inside the bottom tube, a second rotating plate fixed on both sides of the second rotating shaft inside the bottom tube, a sealing block fixed on both sides of the bottom tube outside the second rotating shaft, and a striking rod fixed to one end of the second rotating shaft outside the bottom tube.

[0020] Preferably, the slide rod has a "T" shaped cross-section, the slide rod is slidably connected to the fixed cylinder, the top end of the slide rod is fixedly connected to the bottom side of the bottom tube, and the bottom tube and the fixed cylinder form a telescopic structure through a spring.

[0021] With the above structure, the sliding rod has a "T"-shaped cross-section, which prevents it from falling out of the fixed cylinder during sliding, ensuring the stability of the sliding connection. The extension and contraction of the spring can assist the striking structure to achieve intermittent striking, helping to remove pollutants from the inner wall of the pipe and enhancing the anti-clogging effect.

[0022] Preferably, the second rotating shafts are symmetrically distributed inside the bottom tube, and a "T"-shaped rotating block is fixed to one end of each second rotating shaft. The two ends of the second rotating shaft are rotatably connected to the two sides inside the bottom tube, and the other end of the second rotating shaft is fixedly connected to the side of the striking rod away from the midpoint.

[0023] With the above structure, the axial displacement of the second rotating shaft can be limited during use by the "T"-shaped rotating block, preventing the rotating shaft from falling out of the bottom tube and ensuring the stability of the structure. The second rotating shaft is fixed to the side of the striking rod away from the midpoint, ensuring that the striking rod can swing smoothly and achieve intermittent striking.

[0024] This utility model provides an anti-clogging aeration device for MBR membrane modules used in high-salt industrial wastewater treatment, which has the following advantages:

[0025] With a cleaning structure, the first rotating plate inside the aeration pipe drives the first rotating shaft to rotate under the airflow, so that the brush plate continuously wipes the surface of the filter screen, which can remove salt crystals and pollutant particles from the filter screen pores and surface in real time, avoiding the decrease in aeration efficiency caused by membrane pore blockage.

[0026] By incorporating a striking structure, the extension and retraction vibration of the bottom pipe, in conjunction with the second rotating plate, causes the striking rod to intermittently strike the mounting plate. The resulting mechanical vibration dislodges blocky pollutants adhering to the inner walls of the bottom pipe and aeration pipe, preventing scale buildup inside the pipes from clogging the airflow channels.

[0034] Please see Figures 1-5 This utility model provides an anti-clogging aeration device for MBR membrane modules used in high-salt industrial wastewater treatment, including a mounting plate 1.

[0035] Reference Figures 1-4As shown, a bottom pipe 2 is installed at the top of the mounting plate 1. An air pump 3 is installed on one side of the top of the bottom pipe 2. An air supply pipe 4 is fixed to the output end of the air pump 3. The bottom pipe 2 is rectangular, and the air supply pipe 4 is a four-way pipe. The bottom ends of the air supply pipe 4 are fixedly connected to the top side of the bottom pipe 2. The air supply pipe 4 is connected to the interior of the bottom pipe 2. A cleaning structure 5 is installed inside the bottom pipe 2. The cleaning structure 5 includes a connecting pipe 501 fixed to the inside of the bottom pipe 2. The connecting pipe 501 has a threaded groove 502 inside. An aeration pipe 503 is installed between the connecting pipes 501. An aeration hole 504 is fixed to the top side of the aeration pipe 503. The aeration hole 504 has an internal thread 504 inside. 05. An aeration disc 506 is installed at the top of the aeration hole 504. An installation pipe 507 is fixed to the bottom of the aeration disc 506 inside the internal thread 505. An installation groove 508 is provided at the top of the aeration disc 506. An installation frame 509 is installed inside the installation groove 508. A filter screen 510 is fixed inside the installation frame 509. A bracket 511 is fixed inside the aeration disc 506. A first rotating shaft 512 is installed inside the bracket 511. A fixing sleeve 513 is fixed to the bottom side of the aeration pipe 503 at the bottom of the first rotating shaft 512. First rotating plates 514 are fixed to both sides of the first rotating shaft 512 inside the aeration pipe 503. The top of the filter screen 510... A brush plate 515 is installed on one side of the first rotating shaft 512. A locking block 516 is fixed to one end of the brush plate 515. A locking groove 517 is provided on one side of the first rotating shaft 512 outside the locking block 516. Connecting pipes 501 are evenly distributed on both sides of the inner side of the bottom pipe 2. The two ends of the aeration pipe 503 are threadedly connected to the connecting pipes 501 through threaded grooves 502. The interior of the aeration pipe 503 is connected to the interior of the bottom pipe 2. Aeration holes 504 are evenly distributed on the top side of the aeration pipe 503. The mounting pipe 507 is threadedly connected to the aeration holes 504 through internal threads 505. The mounting frame 509 and the aeration disc 506 are connected through mounting grooves 505. 8 forms a threaded connection. The interior of the aeration disc 506 is connected to the interior of the aeration pipe 503. An installation hole is provided in the middle position inside the filter screen 510. The first rotating shaft 512 is rotatably connected inside the bracket 511. Limit blocks are fixed on the outer side of the first rotating shaft 512 at both ends of the bracket 511. The bottom end of the first rotating shaft 512 is rotatably connected inside the fixing sleeve 513. The first rotating plate 514 is symmetrically distributed on both sides of the first rotating shaft 512 inside the aeration pipe 503. The first rotating plate 514 is semi-circular. The bottom end of the brush plate 515 abuts against the top end of the filter screen 510. The locking block 516 and the locking groove 517 are engaged.

[0036] By activating the air pump 3, compressed air can be quickly filled into the cavity of the bottom pipe 2 through the air supply pipe 4. The compressed air in the bottom pipe 2 enters the interior of the aeration pipe 503 through the connecting pipe 501. The compressed air entering the aeration pipe 503 is further dispersed to the aeration holes 504 evenly distributed on the top side of the aeration pipe 503, and then enters the interior of the aeration disc 506 through the installation pipe 507. Finally, the compressed air passes through the through holes inside the filter screen 510 at the top of the aeration disc 506, achieving uniform airflow diffusion and stably and evenly delivering air to the high-salt industrial wastewater system. This provides sufficient oxygen for the biological reaction of the MBR membrane module, and the airflow disturbance can also initially reduce the adhesion of pollutants on the surface of the filter screen 510. During the aeration process... To prevent salt and pollutants in high-salt wastewater from accumulating and clogging the surface of the filter screen 510, a first rotating shaft 512 is rotatably connected to the bracket 511 fixed inside the aeration disc 506. The bottom end of the first rotating shaft 512 rotates within the fixed sleeve 513, and the limiting block on the outside of the first rotating shaft 512 prevents axial displacement. This causes the semi-circular first rotating plates 514 symmetrically distributed on both sides of the first rotating shaft 512 to rotate under the action of airflow disturbance, driving the brush plate 515 installed on one side of the first rotating shaft 512 to move synchronously. Since the bottom of the brush plate 515 abuts against the top of the filter screen 510, the brush plate 515 can continuously wipe the surface of the filter screen 510 during rotation, removing salt crystals and pollutant particles attached to the through holes and surface of the filter screen 510, ensuring the airflow efficiency of the filter screen 510. At the same time, the locking block 516 fixed at one end of the brush plate 515 is engaged with the locking groove 517 on one side of the bracket 511. When the filter screen 510 needs to be replaced, the locking structure can be quickly unlocked to ensure the disassembly of the mounting frame 509.

[0037] Reference Figure 2 , Figure 4 and Figure 5As shown, a striking structure 6 is fixed to the bottom end of the bottom tube 2. The striking structure 6 includes a fixed cylinder 601 fixed to the top of the mounting plate 1. A sliding rod 602 is installed inside the fixed cylinder 601. A limit plate 603 is fixed to the outer side of the top of the fixed cylinder 601. A spring 604 is installed on the outer side of the sliding rod 602 at the top of the limit plate 603. A second rotating shaft 605 is installed on both sides inside the bottom tube 2. A second rotating plate 606 is fixed on both sides of the second rotating shaft 605 inside the bottom tube 2. A sealing block 607 is fixed on both sides of the bottom tube 2 outside the second rotating shaft 605. One end of each tube is fixed with a striking rod 608. The cross-section of the sliding rod 602 is T-shaped. The sliding rod 602 is slidably connected to the fixed cylinder 601. The top end of the sliding rod 602 is fixedly connected to the bottom side of the bottom tube 2. The bottom tube 2 and the fixed cylinder 601 form a telescopic structure through the spring 604. The second rotating shaft 605 is symmetrically distributed inside the bottom tube 2. One end of the second rotating shaft 605 is fixed with a T-shaped rotating block. The two ends of the second rotating shaft 605 are rotatably connected to the two sides inside the bottom tube 2, respectively. The other end of the second rotating shaft 605 is fixedly connected to the side of the striking rod 608 away from the midpoint.

[0038] A T-shaped sliding rod 602 is slidably connected inside the fixed cylinder 601, and the limiting plate 603 on the outer side of the top of the fixed cylinder 601 cooperates with the spring 604 on the outer side of the sliding rod 602, so that the bottom tube 2 and the fixed cylinder 601 form a telescopic structure. When the device operates and generates slight vibration or airflow impact, the bottom tube 2 can drive the sliding rod 602 to slide up and down inside the fixed cylinder 601. The elastic deformation of the spring 604 can buffer the vibration and provide a restoring force. At the same time, the second rotating plates 606 fixed on both sides of the second rotating shaft 605 symmetrically distributed on both sides inside the bottom tube 2 are driven by the telescopic vibration or airflow of the bottom tube 2. The rotation causes the second rotating shaft 605 to move the striking rod 608. The side of the striking rod 608 furthest from the midpoint is fixed to the second rotating shaft 605, and its end can intermittently strike the top of the mounting plate 1. The mechanical vibration generated by the striking action can dislodge salt crystals and contaminant clumps adhering to the inner wall of the pipe, preventing pipe blockage and affecting airflow. At the same time, the vibration can also be transmitted to the periphery of the filter screen 510, helping to remove stubborn deposits on the surface of the filter screen 510. This complements the cleaning action of the brush plate 515, further improving the overall anti-clogging effect of the device.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
