Description

Technical Field

[0001] This utility model relates to the field of MBR membrane technology, specifically to a modular and quickly replaceable MBR membrane module. Background Technology

[0002] MBR (Membrane Bioreactor) is a novel and highly efficient wastewater treatment process that combines efficient membrane separation technology with the traditional activated sludge process. The MBR system uses a hollow fiber ultrafiltration membrane as its central treatment unit. The MBR membrane frame assembly is placed in an aeration tank. The treated liquid flows through the membrane surface at a certain velocity. Water molecules permeate through the membrane under a certain suction force, while suspended solids, colloids, large organic molecules, and microorganisms are trapped, thus achieving purification and separation. The addition of an aeration system further enhances the bioreactor efficiency of the MBR membrane.

[0003] However, current MBR membrane modules are prone to clogging due to fouling of the membrane fibers, reducing filtration efficiency and necessitating replacement. Traditionally, MBR modules are installed by directly inserting the water collection branch pipes at both ends of the membrane fibers into the mounting pipe of the water collection module. To improve stability after installation, the pipe diameter between the mounting pipe and the water collection branch pipe is designed to be compact, requiring the use of a rubber mallet for assembly. Similarly, disassembly involves significant frictional resistance, making disassembly laborious and inconvenient. Therefore, this invention proposes a modular, quickly replaceable MBR membrane module. Utility Model Content

[0023] Please see Figures 1-4In this embodiment, a modular, quick-replacement MBR membrane module is provided, including an MBR membrane module 1, a water collection module 2, and a support frame 3. The end of the water collection module 2 furthest from the MBR membrane module 1 is connected to a suction pump 5 via a product water pipe 4. The membrane fibers 10 are hollow fiber membrane fibers. The water collection module 2 includes an installation pipe 22, and the support frame 3 includes a sealing installation column 32. The water collection module 2 and the support frame 3 are respectively disposed on both sides of the MBR membrane module 1. The MBR membrane module 1 includes membrane fibers 10, with water collection branch pipes 11 fixedly installed at both the upper and lower ends of the membrane fibers 10. Quick-connect pipes 12 are provided at both ends of the water collection branch pipes 11, and quick-connect fasteners 13 are provided on the quick-connect pipes 12. The MBR membrane module 1 is fixedly installed on the installation pipes via the quick-connect fasteners 13. On the quick-connect fastener 13 and the sealing mounting post 32, the quick-connect fastener 13 includes an elastic lotus claw 132 disposed at the end of the quick-connect pipe 12 away from the water collection branch pipe 11, and one end of the elastic lotus claw 132 is fixedly connected to the quick-connect pipe 12. The outer surface of the quick-connect pipe 12 is threadedly connected to a tightening sleeve 131, and the inner surface of the tightening sleeve 131 is provided with a limiting groove 133. The elastic lotus claw 132 is disposed in the limiting groove 133. The two ends of the limiting groove 133 are respectively provided with a quick-connect pipe receiving cavity and an installation component receiving cavity. The quick-connect pipe 12 is disposed in the quick-connect pipe receiving cavity, and the installation pipe 22 or the sealing mounting post 32 is disposed in the installation component receiving cavity. The limiting groove 133 has a frustum-shaped structure. The elastic lotus claw 132 includes multiple elastic cones, which are arranged in a ring on the quick-connect pipe 12. At the end of pipe 12, the inner surface of the tightening sleeve 131 is provided with an internal thread 134, and the outer surface of the quick-connect pipe 12 is provided with an external thread 120 that matches the internal thread 134. A sealing ring 135 is provided on the outer surface of the mounting pipe 22. The water collection assembly 2 also includes a main water collection pipe 21. There are two sets of mounting pipes 22, located at the top and bottom of one side of the main water collection pipe 21, respectively. The number of mounting pipes 22 in each set is the same as the number of MBR membrane modules 1. The support frame 3 also includes a support rod 31. There are two sets of sealing mounting columns 32, located at the top and bottom of one side of the support rod 31, respectively. The number of sealing mounting columns 32 in each set is the same as the number of MBR membrane modules 1. Specifically, when the water collection... When one or more MBR membrane modules 1 on the water assembly 2 are damaged and need to be replaced, simply rotate the tightening sleeve 131 on the MBR membrane module 1 to separate the tightening sleeve 131 from the quick-connect pipe 12. During the separation process, since the elastic lotus claw 132 is no longer limited by the limiting groove 133, the side of the elastic cone on the elastic lotus claw 132 away from the quick-connect pipe 12 can open, similar to a lotus flower blooming. This allows the elastic lotus claw 132, which is fastened to the installation pipe 22 or the sealing installation column 32, to unfold. Then, the installation pipe 22 or the sealing installation column 32 can be easily separated from the quick-connect pipe 12, realizing the separation of the MBR membrane module 1 from the water collection assembly 2 and the support frame 3. Similarly, when the MBR membrane module 1 needs to be installed...First, insert the mounting tube 22 or the sealing mounting post 32 into the tightening sleeve 131, extending it deep into the quick-connect tube 12. Then, rotate the tightening sleeve 131 in the opposite direction to that used during disassembly. This allows the tightening sleeve 131 to move horizontally on the surface of the quick-connect tube 12. During this movement, the movement of the limiting groove 133 gradually compresses the elastic cone of the elastic lotus claw 132, thus allowing the elastic lotus claw 132 to be fixedly gripped against the outer surface of the mounting tube 22 or the sealing mounting post 32. This achieves the fixed installation of the mounting tube 22 or the sealing mounting post 32 with the quick-connect tube 12, utilizing the sealing ring 1. 35 can achieve a good sealing effect, and by using the sealing mounting column 32, one end of the water collection branch pipe 11 can be sealed, so that the produced purified water can be discharged through one end of the water collection component 2, which facilitates the purified water collection work. It should be noted that one end of the support frame 3 is provided with the MBR membrane device frame 6, and the MBR membrane device frame 6 is provided with a sliding groove 60. A slider 61 is slidably installed in the sliding groove 60, and mounting plates 62 are provided on both sides of the slider 61. The mounting plates 62 are provided with mounting holes. The MBR membrane device frame 6 is provided with corresponding fixing threaded holes in the sliding groove 60, which can be fixed by screws. The slider 61 is fixed in the groove 60 to achieve a fixed connection between the MBR membrane unit frame 6 and the support frame 3. When installing both ends of the MBR membrane module 1 onto the water collection component 2 and the support frame 3, the support frame 3 needs to be moved away from the water collection component 2 first, that is, the installation space between the water collection component 2 and the support frame 3 needs to be adjusted and expanded to facilitate the alignment and placement of the MBR membrane module 1 before installation. Then, one end of the MBR membrane module 1 is fixed to the water collection component 2. After all the MBR membrane modules 1 and water collection components 2 are installed, the position of the support frame 3 is adjusted so that the support frame 3 faces the MBR... The membrane module 1 moves away from the water collection component 2 until the sealing mounting post 32 is engaged with the quick-connect pipe 12. Then, the tightening sleeve 131 of the quick-connect pipe 12 is rotated. By providing the quick-connect pipe 12 and quick-connect fastener 13 on the MBR membrane module 1, rapid installation or removal between the MBR membrane module 1 and the water collection component 2 or support frame 3 can be achieved. This allows for rapid modular replacement of the MBR membrane module 1 on the MBR membrane frame device. During installation, no rubber mallet is needed for fixing, and during disassembly, no force is required, thus improving the efficiency of modular replacement of the MBR membrane module 1.
