Description

Technical Field

[0001] This utility model relates to the field of MBR membrane bioreactor technology, and in particular to an MBR membrane bioreactor for an industrial wastewater treatment system. Background Technology

[0002] With the rapid development of industrialization and urbanization, water shortage and water pollution problems are becoming increasingly serious. The discharge of industrial wastewater is constantly increasing, and its composition is complex, containing a large amount of organic matter, heavy metals, nitrogen and phosphorus pollutants. Traditional sewage treatment technologies are difficult to meet the increasingly stringent environmental protection requirements and water reuse needs. However, MBR membrane bioreactor technology has advantages such as high efficiency and stability in treating industrial wastewater, which can effectively purify and reuse water resources and alleviate the pressure of water shortage.

[0003] Existing MBR membrane bioreactors cannot disinfect the effluent during use, making it easy for pathogens to remain in the water. At the same time, existing MBR membrane bioreactors are bulky, occupy a large area, and are inconvenient to use. Therefore, it is necessary to design an MBR membrane bioreactor.

[0004] The existing patent (publication number: CN211664779U) describes an MBR membrane bioreactor. This MBR membrane bioreactor is compact in size, occupies little space, and is not limited by the installation location. It has a good disinfection effect, which can disinfect the effluent and improve the safety of the effluent quality. Moreover, the effluent quality is high-quality and stable, which effectively improves the overall removal rate of pollutants, produces less sludge, and can effectively remove ammonia nitrogen and recalcitrant organic matter.

[0005] To address the aforementioned issues, existing patents offer solutions. In conventional industrial wastewater treatment systems, MBR membrane bioreactors are typically placed in wastewater for reaction. However, during installation, the MBR membrane bioreactor requires multiple bolts for fixation. After prolonged immersion, these bolts are prone to rusting, making subsequent disassembly and maintenance difficult. Furthermore, they do not provide adequate cushioning protection for the MBR membrane bioreactor, which can easily damage its internal precision parts and affect its service life when shaking occurs.

[0006] Therefore, an MBR membrane bioreactor for industrial wastewater treatment system is proposed. Utility Model Content

[0007] The purpose of this invention is to provide an MBR membrane bioreactor for an industrial wastewater treatment system. This invention addresses the problem that existing industrial wastewater treatment systems typically use MBR membrane bioreactors that are placed in wastewater for reaction. However, during installation, the MBR membrane bioreactor requires multiple bolts for fixation. After prolonged immersion, these bolts are prone to rust, making subsequent disassembly and maintenance difficult. Furthermore, they do not provide adequate cushioning protection for the MBR membrane bioreactor, which can easily damage its internal precision parts and affect its service life when shaken.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an MBR membrane bioreactor for an industrial wastewater treatment system, comprising a protective frame, an MBR membrane bioreactor body being movably connected inside the protective frame, fixing components being fixedly connected to both sides of the protective frame, and an auxiliary component being provided at the top of the protective frame.

[0009] The fixing assembly includes a fixing support fixedly connected to the outside of the protective frame. A fixing seat is slidably connected inside the fixing support. A fixing rod is inserted into the top of the fixing seat. A support seat is fixedly connected to the outside of the fixing seat. A support rod is fixedly connected to the outside of the support seat. A support rod is slidably connected inside the support rod. A fixing groove is opened at the top of the support rod. A fixing connecting rod is inserted into the top of the support rod. The fixing connecting rod is engaged with the fixing groove. A fixing sleeve is fixedly connected to the outside of the support rod.

[0010] Preferably, the auxiliary component includes a placement slot formed inside the protective frame, an auxiliary rod is fixedly connected inside the placement slot, and a push spring is fixedly connected inside the auxiliary rod.

[0011] Preferably, an auxiliary connecting rod is fixedly connected to the outside of the push spring, and a sealing ring is sleeved on the outside of the auxiliary rod.

[0012] Preferably, a support plate is fixedly connected to the outer side of the auxiliary connecting rod, and a protective pad is adhered to the outer side of the support plate.

[0013] Preferably, a connecting column is fixedly connected to the top of the protective frame, a connecting rope is fixedly connected to the outside of the connecting column, and a lifting ring is fixedly connected to the inside of the connecting rope.

[0015] Preferably, the fixed support has a groove inside, and a slider is slidably connected inside the groove, and the slider is fixedly connected to the fixed support.

[0016] Preferably, a base is fixedly connected to the bottom of the protective frame, and a cushioning rubber pad is fixedly connected to the top of the base.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application can adapt to different installation environments through its fixing components. In complex industrial sites, the best fixing position can be found by adjusting its components, thereby improving the convenience and stability of reactor installation and ensuring its reliable operation under various working conditions. At the same time, its fixing method can achieve quick disassembly and maintenance and achieve a stable fixing effect to ensure stable fixing of the MBR membrane bioreactor.

[0019] 2. This application achieves good buffering protection through auxiliary components. When the reactor is subjected to external collision or vibration, the spring is compressed and deformed to absorb part of the impact force. The auxiliary connecting rod drives the support plate and protective pad to move. The protective pad comes into contact with surrounding objects to further buffer and disperse the impact force, preventing the reactor body from directly colliding with external objects. This effectively protects the reactor body and its internal precision components and reduces the risk of damage. Attached Figure Description

[0028] 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.

[0029] Please see Figure 1-7 The present invention provides the following technical solution:

[0030] An MBR membrane bioreactor for an industrial wastewater treatment system includes a protective frame 1, an MBR membrane bioreactor body 2 movably connected inside the protective frame 1, fixing components 4 fixedly connected to both sides of the protective frame 1, and an auxiliary component 5 provided on the top of the protective frame 1.

[0031] The fixing component 4 includes a fixing support 401 fixedly connected to the outside of the protective frame 1. A fixing seat 402 is slidably connected inside the fixing support 401. A fixing rod 403 is inserted into the top of the fixing seat 402. A support seat 404 is fixedly connected to the outside of the fixing seat 402. A support rod 405 is fixedly connected to the outside of the support seat 404. A support rod 406 is slidably connected inside the support rod 405. A fixing groove 407 is opened at the top of the support rod 406. A fixing connecting rod 408 is inserted into the top of the support rod 405. The fixing connecting rod 408 is engaged with the fixing groove 407. A fixing sleeve 409 is fixedly connected to the outside of the support rod 406.

[0032] In this embodiment: by moving the fixing rod 403 upward, the fixing rod 403 drives the fixing plate 8 to slide inside the fixing seat 402. At the same time, the fixing plate 8 exerts pressure on the top limiting spring 9 and causes it to contract. Then, the fixing rod 403 disengages from the positioning groove 10 located inside the fixing support 401, thereby releasing the fixation between the fixing seat 402 and the fixing support 401. Next, by sliding the fixing seat 402 within the fixing support 401, the position is adjusted to a suitable fixing point. Then, the fixing rod 403 is released, immediately releasing the pressure on the limiting spring 9. The compressed limiting spring 9 then exerts downward pressure. The elastic force drives the fixing plate 8 to move downwards. Then, the fixing plate 8 drives the fixed rod 403 to move downwards, so that the bottom of the fixing rod 403 re-engages with the positioning groove 10 to complete the fixation between the fixing support 401 and the fixing seat 402. Then, the fixing connecting rod 408 is taken out, and then the support rod 406 is moved to slide inside the support rod 405 to adjust to a suitable position. The fixing connecting rod 408 is reinserted, and then the fixing connecting rod 408 re-engages with the fixing groove 407 at the top of the support rod 406 to adapt to the installation of MBR membrane bioreactors in different positions and of different sizes.

[0033] Specifically, such as Figure 3 , Figure 7 As shown, the auxiliary component 5 includes a placement slot 501 opened inside the protective frame 1, an auxiliary rod 502 is fixedly connected inside the placement slot 501, and a push spring 503 is fixedly connected inside the auxiliary rod 502.

[0034] Specifically, such as Figure 3 , Figure 7 As shown, an auxiliary connecting rod 504 is fixedly connected to the outside of the push spring 503, and a sealing ring 505 is sleeved on the outside of the auxiliary rod 502.

[0035] Specifically, such as Figure 3 , Figure 7 As shown, a support plate 506 is fixedly connected to the outer side of the auxiliary connecting rod 504, and a protective pad 507 is adhered to the outer side of the support plate 506.

[0036] In this embodiment: the vibration and impact force are transmitted through the support plate 506, and then the support plate 506 transmits its power to the inner auxiliary connecting rod 504, causing the auxiliary connecting rod 504 to slide inside the auxiliary rod 502. Then the auxiliary rod 502 compresses the push spring 503 to reduce the impact force on the MBR membrane bioreactor body 2 and protect the MBR membrane bioreactor body 2. At the same time, the bottom buffer rubber pad 14 can reduce the impact of vibration on the internal structure of the MBR membrane bioreactor body 2 and ensure its stable operation. Meanwhile, the sealing ring 505 sleeved on the outside of the auxiliary rod 502 plays a role in sealing and reducing friction, ensuring that the auxiliary connecting rod 504 can slide smoothly on the auxiliary rod 502, while preventing external impurities from entering the interior of the auxiliary rod 502.

[0037] Specifically, such as Figure 4 As shown, a connecting column 3 is fixedly connected to the top of the protective frame 1, a connecting rope 6 is fixedly connected to the outside of the connecting column 3, and a lifting ring 7 is fixedly connected to the inside of the connecting rope 6.

[0038] Specifically, such as Figure 5 As shown, a fixing plate 8 is fixedly connected to the bottom of the fixing rod 403. The fixing plate 8 is slidably connected to the fixing seat 402. A limit spring 9 is provided on the top of the fixing plate 8. A positioning groove 10 is provided inside the fixing support 401. The positioning groove 10 is engaged with the fixing rod 403.

[0039] In this embodiment: By setting up connecting column 3, connecting rope 6, and lifting ring 7, when the reactor needs to be moved to a designated location, the operator will use connecting column 3, connecting rope 6, and lifting ring 7 to carry out the lifting operation. First, the hook of the lifting equipment is firmly connected to the lifting ring 7 to ensure that the connection is firm and reliable and there is no risk of falling off during the lifting process. Then, the lifting equipment is slowly lifted, and the connecting rope 6 will be tightened due to the force, thereby driving the connecting column 3 and the entire protective frame 1 to rise, so as to realize the smooth lifting of the reactor. After being lifted to the target location, the reactor is slowly lowered to complete the adjustment of the installation position or the transfer of the equipment. By setting up fixing plate 8, limiting spring 9, and positioning groove 10, during the removal of fixing rod 403, its limiting spring 9 will generate elastic resistance. As fixing rod 403 moves upward, its limiting spring 9 is compressed to store elastic potential energy. When the upward tension of fixing rod 403 is released, the elastic force of its limiting spring 9 makes fixing rod 403 re-fixed between fixing groove 407.

[0040] Specifically, such as Figure 3 As shown, the fixed support 401 has a groove 11 inside, and a slider 12 is slidably connected inside the groove 11. The slider 12 is fixedly connected to the fixed support 402.

[0041] Specifically, such as Figure 4As shown, a base 13 is fixedly connected to the bottom of the protective frame 1, and a buffer rubber pad 14 is fixedly connected to the top of the base 13.

[0042] In this embodiment: by setting the slide groove 11 and the slider 12, when the horizontal position of the fixing component 4 needs to be adjusted, the slider 12 will slide smoothly in the slide groove 11, driving the fixing seat 402 and other connected components to move together. After being adjusted to a suitable position, the fixing seat 402 will remain stable in the new position, waiting for subsequent fixing operations, such as inserting the fixing rod 403 and making it engage with the positioning groove 10. By setting the base 13 and the buffer rubber pad 14, the base 13 ensures the stability of the MBR membrane bioreactor body 2 and prevents the equipment from tipping over due to an unstable center of gravity. At the same time, the presence of the buffer rubber pad 14 effectively reduces the damage of vibration to the internal components of the reactor and extends the service life of the equipment.

[0043] Working Principle: In the process of using the MBR membrane bioreactor in an industrial wastewater treatment system, firstly, according to the installation environment and requirements, the fixing rod 403 is moved upward. Then, the fixing rod 403 drives the fixing plate 8 to slide inside the fixing seat 402. At the same time, the fixing plate 8 exerts pressure on the top limiting spring 9 and causes it to contract. Then, the fixing rod 403 disengages from the positioning groove 10 located inside the fixing support 401, thereby releasing the fixation between the fixing seat 402 and the fixing support 401. Next, the position of the fixing seat 402 within the fixing support 401 is adjusted to a suitable fixing point by sliding the fixing seat 402. Then, the... Opening the fixing rod 403 immediately releases the pressure on the limiting spring 9. The compressed limiting spring 9 then generates a downward elastic force, causing the fixing plate 8 to move downwards. The fixing plate 8 then moves the fixedly connected fixing rod 403 downwards, causing the bottom of the fixing rod 403 to re-engage with the positioning groove 10, thus completing the fixation between the fixing support 401 and the fixing seat 402. Next, remove the fixing connecting rod 408. Then, move the support rod 406 to slide inside the support rod 405, adjusting it to a suitable position. Reinsert the fixing connecting rod 408, and then the fixing connecting rod 408 re-engages with the top of the support rod 406. The fixing slot 407 is used for snap-fit ​​to accommodate the installation of MBR membrane bioreactors in different positions and of different sizes. Then, using the connecting ropes 6 and lifting rings 7 on the connecting column 3, the reactor is lifted to the designated position using lifting equipment. It is then fixed to the position using the fixing sleeve 409. During reactor operation, its protective pad 507 prevents the reactor from colliding with surrounding objects and being damaged. When the reactor is subjected to external vibration or impact, the vibration and impact force are transmitted to the support plate 506. The support plate 506 then transmits its force to the inner auxiliary connecting rod 504, driving the auxiliary connecting rod 504. 4. The auxiliary rod 502 slides inside the auxiliary rod 502, and then the auxiliary rod 502 compresses the push spring 503 to reduce the impact of the impact force on the MBR membrane bioreactor body 2 and protect the MBR membrane bioreactor body 2. At the same time, the buffer rubber pad 14 at the bottom can reduce the impact of vibration on the internal structure of the MBR membrane bioreactor body 2 and ensure its stable operation. Meanwhile, the sealing ring 505 sleeved on the outside of the auxiliary rod 502 plays a role in sealing and reducing friction, ensuring that the auxiliary connecting rod 504 can slide smoothly on the auxiliary rod 502, while preventing external impurities from entering the interior of the auxiliary rod 502.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
