Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a high-efficiency, low-consumption membrane bioreactor. Background Technology

[0002] In the fields of wastewater and industrial wastewater treatment, membrane bioreactors (MBRs) have been widely used due to their high efficiency in solid-liquid separation and stable effluent quality. However, traditional membrane bioreactors face many problems in actual operation, which seriously restrict their treatment efficiency and application scope. First, in terms of impurity treatment, traditional membrane bioreactors lack an effective pretreatment mechanism for larger impurities in the liquid. Untreated larger impurities directly enter the filtration stage, easily clogging the filter plates, leading to a sharp drop in filtration efficiency. Once the filter plates are clogged, not only do they need to be replaced frequently, increasing maintenance costs, but they also cause poor liquid flow, affecting the overall operational stability of the reactor. Second, in terms of filter plate maintenance, the disassembly and installation of filter plates in traditional membrane bioreactors are complex and cumbersome to operate. Traditional membrane bioreactors typically require multiple tools and demand a high level of technical expertise, increasing maintenance time and downtime, impacting production efficiency. Frequent and complex disassembly can also damage filter plates and other reactor components, further increasing maintenance costs and difficulty. Furthermore, in the bioreactor stage, traditional membrane bioreactors often employ a static reaction mode, resulting in insufficient contact between the liquid and the biofilm. Microorganisms cannot promptly and adequately contact and decompose organic pollutants in the liquid, leading to low bioreactor efficiency. Therefore, we propose a high-efficiency, low-consumption membrane bioreactor to address this problem. Utility Model Content

The sedimentation tower has an internal connecting pipe with a water inlet pipe at one end, which extends into the pulverizing chamber. The pulverizing chamber contains a pulverizing assembly, which includes: two sets of rotating shafts rotatably mounted on the inner walls of both sides of the pulverizing chamber; two sets of crushing blades fixedly mounted on the outer sides of each set of rotating shafts, and the two sets of crushing blades meshing with each other; a drainage hopper fixedly mounted at the bottom of the pulverizing chamber; and a filter box fixedly mounted at the bottom of the drainage hopper. The filter box has a slidingly mounted... The filter box has a filter plate, and both sides of the filter box have placement slots. Each of the two placement slots has a disassembly assembly. The disassembly assembly includes: a frame, a block fixedly installed on one side of the frame, the block being movably inserted into the filter plate; a connecting plate on one side of the frame, a sliding rod slidably installed inside the connecting plate; a pull plate fixedly installed at one end of the connecting plate; a filter tube fixedly installed at the bottom of the filter box; a reaction chamber at the bottom of the filter tube; and two sets of perforated frames inside the reaction chamber, with a biofilm inside each set of perforated frames.

[0006] Preferably, square plates are fixedly installed on the inner walls of the top two sides of the reaction chamber, the filter tube extends through to the bottom of the square plates, two sets of stirring shafts are rotatably installed inside the square plates, multiple sets of connecting rings are fixedly installed on the outer side of each of the two sets of stirring shafts, multiple sets of stirring rods are fixedly installed on the outer side of each of the multiple sets of connecting rings, and two sets of motors are fixedly installed on the top of the square plates, with the output shafts of the two sets of motors respectively fixedly connected to the corresponding stirring shafts.

[0007] Preferably, the connecting pipe extends through to one side of the sedimentation tower, a pump body is fixedly installed at one end of the sedimentation tower, one end of the pump body is fixedly connected to the water inlet pipe, both sets of rotating shafts extend through to one side of the crushing box, gears are fixedly installed on the outer side of both sets of rotating shafts, the two sets of gears mesh with each other, a second motor is fixedly installed on one side of the crushing box, and the output shaft of the second motor is fixedly connected to the rotating shaft located on the left side.

[0008] Preferably, the two sets of frames are slidably installed inside the corresponding placement slots, and springs are provided on the outer sides of the two sets of slide rods. The two ends of the two sets of springs are fixedly connected to the corresponding connecting plate and the inner wall of one side of the frame, respectively.

[0009] Preferably, each of the two sets of frames is provided with a second spring, and the two ends of the two sets of springs are respectively fixedly connected to the inner wall of one side of the corresponding frame and the placement slot. Each of the two sets of crushing boxes is fixedly installed with a card plate on one side, and the two sets of card plates are respectively movably engaged with the inside of the corresponding connecting plate.

[0010] Preferably, a long plate is fixedly installed on the top of each of the two sets of hollow frames, and an mounting plate is fixedly installed on the bottom of each of the two sets of long plates. The mounting plates are movably inserted into the inside of both sides of the reaction chamber. A drain pipe is fixedly installed at the bottom of the reaction chamber. A sewage outlet is opened at the bottom of the sedimentation tower. Two sets of brackets are fixedly installed on one side of the sedimentation tower. The two sets of brackets are fixedly connected to the crushing box and the filter box, respectively.

[0011] In this invention, a high-efficiency, low-consumption membrane bioreactor is provided, comprising a filter plate, a disassembly assembly, and a pulverizing assembly. When motor two starts, its output shaft drives the left-side rotating shaft to rotate. Gears on the outer side of the left-side rotating shaft mesh, and two sets of crushing blades mesh with each other to cut and pulverize larger impurities in the liquid into smaller particles. The filter plate intercepts larger particles in the liquid after pulverization, allowing a relatively pure liquid to pass through. When the filter plate needs cleaning or replacement, pulling the pull plate causes the connecting plate to slide along the slide rod, compressing spring one. Simultaneously, the frame slides within the placement groove, compressing spring two. The insert block on one side of the frame detaches from the inside of the filter plate, at which point the filter plate can be removed from the filter box for maintenance. This process cuts and crushes larger impurities in the liquid into smaller particles, greatly reducing the particle size of the impurities and making them easier for the filter plate to intercept. This allows the filter plate to separate impurities in the liquid more efficiently, ensuring that the liquid passing through the filter plate is purer. It also reduces the filtration burden on the filter plate and prevents the filter plate from being affected by excessive pressure or blockage, thus ensuring the normal flow of the liquid. The disassembly component has a simple structure and is easy to operate, making it easy to quickly install and remove the filter plate, and easy to maintain, clean and replace the filter plate, thus extending the service life of the filter plate.

[0012] This invention discloses a high-efficiency, low-consumption membrane bioreactor. It comprises a stirring shaft, a connecting ring, a stirring rod, a perforated frame, and a biofilm. Two sets of perforated frames within the reaction chamber are fitted with the biofilm, which is covered with a large number of microorganisms. These microorganisms decompose organic pollutants in the liquid, achieving purification. When two motors are started, their output shafts drive the corresponding stirring shafts to rotate. The connecting ring and stirring rod on the outside of the stirring shafts rotate accordingly, stirring the liquid within the reaction chamber. Compared to traditional static reaction modes, this significantly improves the efficiency of the biological reaction, thereby shortening the entire purification process time and increasing the processing capacity of the membrane bioreactor. It can purify more liquid per unit time. The perforated frame, along with the biofilm, can be easily removed from the reaction chamber without complex tools or cumbersome steps. This design reduces the complexity and time cost of maintenance. Attached Figure Description

[0022] In this embodiment, square plates are fixedly installed on the inner walls of both sides of the top of the reaction chamber 9. Filter tubes 8 penetrate to the bottom of the square plates. Two sets of stirring shafts 10 are rotatably installed inside the square plates. Multiple sets of connecting rings 11 are fixedly installed on the outer sides of both sets of stirring shafts 10. Multiple sets of stirring rods 12 are fixedly installed on the outer sides of the multiple sets of connecting rings 11. Two sets of motors are fixedly installed on the top of the square plates. The output shafts of the two sets of motors are respectively fixedly connected to the corresponding stirring shafts 10, which facilitates thorough stirring of the liquid and microorganisms, making their reaction and decomposition efficiency faster. The connecting pipe 2 extends through to one side of the sedimentation tower 1. A pump body is fixedly installed at one end of the sedimentation tower 1, and one end of the pump body is fixedly connected to the water inlet pipe. Both sets of rotating shafts 401 rotate through to one side of the crushing box 3. Gears 403 are fixedly installed on the outer side of both sets of rotating shafts 401. The two sets of gears 403 mesh with each other. A second motor is fixedly installed on one side of the crushing box 3. The output shaft of the second motor is fixedly connected to the rotating shaft 401 located on the left side, which facilitates the rotation of the two sets of gears 403 and the crushing blade 402, and facilitates the crushing of impurities inside the liquid.

[0023] In this embodiment, two sets of frames 603 are slidably installed inside corresponding placement slots. Springs 606 are provided on the outer sides of both sets of slide rods 605. The two ends of each spring 606 are fixedly connected to the corresponding connecting plate 602 and one inner wall of the frame 603, facilitating the repositioning of the insert block 604 and the fixing and disassembly of the filter plate 7. Springs 607 are provided inside both sets of frames 603. The two ends of each spring 607 are fixedly connected to the corresponding frame 603 and one inner wall of the placement slot. A clip is fixedly installed on one side of each of the two crushing boxes 3. Plate 608, two sets of clamping plates 608 are respectively movably clamped into the interior of the corresponding connecting plate 602, facilitating the fixation of the connecting plate 602 and preventing the filter plate 7 from being accidentally pulled out. Long plates 13 are fixedly installed on the top of each of the two sets of hollow frames 15, and mounting plates 16 are fixedly installed on the bottom of each of the two sets of long plates 13. The two sets of mounting plates 16 are movably inserted into the interior of both sides of the reaction chamber 9. A drain pipe is fixedly installed at the bottom of the reaction chamber 9. A drain outlet is opened at the bottom of the sedimentation tower 1. Two sets of supports are fixedly installed on one side of the sedimentation tower 1, and the two sets of supports are respectively fixedly connected to the crushing box 3 and the filter box 5. This facilitates the normal operation of the device.

[0024] In this embodiment, during use, the liquid containing impurities enters the sedimentation tower 1 through the connecting pipe 2. Inside the sedimentation tower 1, larger particles of impurities in the liquid settle due to gravity, achieving preliminary sedimentation and separation. The drain outlet at the bottom of the sedimentation tower 1 can periodically discharge the settled impurities. The liquid that has undergone preliminary sedimentation is then pumped to the crushing box 3 through the inlet pipe by the pump. The pump provides power to ensure smooth flow of the liquid, completing the transfer from the sedimentation tower 1 to the crushing box 3. After the liquid enters the crushing box 3, the motor 2 starts, and its output shaft drives the left rotating shaft 401 to rotate. The gear 403 on the outside of the left rotating shaft 401 drives the right rotating shaft 401 to rotate synchronously through meshing transmission. The crushing blades 402 fixedly installed on the two sets of rotating shafts 401 rotate accordingly, and the two sets of crushing blades 402 mesh with each other. The filter plate 7 cuts and crushes larger impurities in the liquid into smaller particles, facilitating subsequent filtration and treatment. The crushed liquid and impurities flow into the filter box 5 through the drain hopper. After entering the filter box 5, the liquid is filtered by gravity through the filter plate 7. The filter plate 7 can intercept larger particles of impurities in the liquid after crushing, allowing a relatively pure liquid to pass through. When it is necessary to clean or replace the filter plate 7, pull the pull plate 601. The pull plate 601 drives the connecting plate 602 to slide along the slide rod 605, causing the connecting plate 602 to compress the first spring 606. At the same time, the frame 603 slides in the placement groove and compresses the second spring 607. The insert block 604 on one side of the frame 603 disengages from the inside of the filter plate 7. At this time, the filter plate 7 can be removed from the filter box 5 for maintenance. After maintenance, release the pull plate 601. Under the reset action of the first spring 606 and the second spring 607, the insert block 604 is reinserted into the filter plate 7, realizing the quick installation of the filter plate 7. The filtered liquid enters the reaction chamber 9 through the filter pipe 8. Two sets of perforated frames 15 inside the reaction chamber 9 are fitted with biofilms 14, which are covered with a large number of microorganisms. These microorganisms can decompose organic pollutants in the liquid, achieving purification. Simultaneously, when the two motors at the top of the square plate are started, their output shafts drive the corresponding stirring shafts 10 to rotate. The connecting ring 11 and stirring rod 12 on the outer side of the stirring shaft 10 rotate accordingly, stirring the liquid in the reaction chamber 9. This ensures full contact between the liquid and the biofilm 14, accelerating the decomposition of pollutants by microorganisms and improving the efficiency of the biological reaction. The treated liquid can be discharged through the drain pipe at the bottom of the reaction chamber 9, completing the entire purification process. When it is necessary to replace the biofilm 14, the mounting plate 16 is detached from the inside of the reaction chamber 9 by pulling the long plate 13 upwards, facilitating the removal of the perforated frames 15 from the inside of the reaction chamber 9 and the replacement of the biofilm 14.

[0025] The above provides a detailed description of the high-efficiency, low-consumption membrane bioreactor provided by this utility model. Specific embodiments have been used to illustrate the principles and implementation methods of this utility model. The descriptions of these embodiments are merely for the purpose of helping to understand the method and core ideas of this utility model.
