[0002] MBR is a new type of wastewater treatment system that combines ultrafiltration and microfiltration membrane modules in membrane separation technology with bioreactors used in biological wastewater treatment. This technology combines the advantages of membrane separation and biological treatment and is currently attracting attention as a high-efficiency wastewater treatment technology.

This system, which relates to wastewater treatment technology, includes a treatment tank and an MBR membrane frame. A connection plate is welded to the top of the treatment tank, and an outlet is installed at the bottom.

[0004] The design of the above device makes the disassembly and replacement of the MBR membrane frame simple and convenient. However, during the actual operation, the treatment box needs to be removed from the sewage pipe and then reinstalled. The operation is time-consuming, and frequent disassembly and assembly will also affect the sealing of the two. There is room for improvement. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0024] The utility model provides a technical solution: Figure 2 and Figure 4As shown, in this embodiment, the integrated sewage treatment MBR membrane assembly includes a base 1 and a treatment tank 2. The base 1 is fixedly connected to the bottom of the circumferential outer wall of the treatment tank 2. A removal assembly 6 is installed inside the base 1. The removal assembly 6 includes the same screw rod 601 rotatably connected to the inner walls on both sides of the base 1, and the screw rod 601 is horizontally arranged. A movable seat 602 is provided on the external threaded sleeve of the screw rod 601, and the movable seat 602 is fitted with the inner wall of the bottom of the base 1. Two limit rods 603 are fixedly connected to the inside of the base 1, and the movable seat 602 is slidably sleeved on the outside of the two limit rods 603.

[0025] A motor 604 is fixedly mounted on the outer wall of one side of the base 1. The output end of the motor 604 is coaxially fixed to one end of the screw rod 601. The thread lead angle of the screw rod 601 is smaller than the equivalent friction angle, making it self-locking and preventing the position of the movable seat 602 connected thereto from changing arbitrarily.

[0026] Start the motor 604 outside the base 1, and the motor 604 drives the screw 601 to start rotating. The movable seat 602 is driven by the screw 601 and cooperates with the limit rod 603. The movable seat 602 will move away from the treatment tank 2 in the horizontal direction. Then the MBR membrane is driven to follow the movable seat 602 and completely leave the internal space of the treatment tank 2. At this time, the replacement operation can be started, which is more convenient.

[0027] like Figure 2 and Figure 3 As shown, a transposition component 7 is installed on the top of the movable seat 602, and the transposition component 7 includes two support rods 701 fixedly connected at both ends of the outer wall of the top of the movable seat 602. One end of the top of the two support rods 701 is rotatably connected to the same connecting frame 702, and a sealing plate 703 is fixedly connected to the outside of both sides of the connecting frame 702, and the two sealing plates 703 are symmetrically arranged, and a through hole adapted to the sealing plate 703 is opened on the circumferential outer wall of the processing tank 2.

[0028] A positioning mechanism is installed at both ends of the rotating shaft of the connecting frame 702. The positioning mechanism includes an extension plate 704 fixedly connected to the outer wall of the circumference of the rotating shaft of the connecting frame 702. A positioning column 705 is slidably inserted inside the extension plate 704. Two limiting holes 706 are provided on the outer wall of one end of the support rod 701, and one end of the positioning column 705 can enter the inside of the two limiting holes 706.

[0029] A spring 707 is sleeved on the exterior of the positioning post 705 , and two ends of the spring 707 are fixedly connected to the extension plate 704 and the positioning post 705 respectively.

[0030] Flip the connecting frame 702, and the rotating shaft of the connecting frame 702 drives the positioning column 705 to rotate synchronously through the extension plate 704. The tension of the spring 707 is overcome and becomes longer, and then it disengages from the limiting hole 706. When the positioning column 705 moves to correspond to the position of another limiting hole 706, the stretched positioning column 705 can drive the positioning column 705 to enter the other limiting hole 706. At this time, the operation can be stopped, and the positions of the two sealing plates 703 installed on both sides of the connecting frame 702 will be swapped. Finally, the new MBR membrane can be driven into the treatment tank 2 again, and there is enough time to replace or clean the old MBR membrane.

[0031] like Figure 1 and Figure 2 As shown, a membrane frame 5 is fixedly connected to the inner wall of each of the two sealing plates 703 . MBR membranes are arranged inside the two membrane frames 5 . After passing through the membrane frames 5 , the sewage will be filtered by the MBR membranes therein.

[0032] like Figure 1 and Figure 2 As shown, a sealing ring 3 is provided on the outer fixed sleeve of the sealing plate 703, and a sealing strip 4 is provided on one side of the circumferential outer wall of the membrane frame 5. The sealing ring 3 can increase the sealing performance between the sealing plate 703 and the through hole of the processing tank 2, and the sealing strip 4 can increase the sealing performance between the membrane frame 5 and the inner wall of the processing tank 2.

[0033] This utility model provides an integrated MBR membrane assembly for sewage treatment, and the specific working principle is as follows:

[0034] After the MBR membrane has been used for a period of time, the impurities accumulated on the membrane gradually increase. As long as the motor 604 outside the base 1 is started, the motor 604 drives the screw 601 to start rotating. The movable seat 602 is driven by the screw 601 and cooperates with the limit rod 603. The movable seat 602 will move away from the treatment tank 2 in the horizontal direction. Then the MBR membrane is driven to follow the movable seat 602 and completely leave the internal space of the treatment tank 2. At this time, the replacement operation can be started, which is more convenient. Then flip the connecting frame 702. The rotating shaft of the connecting frame 702 passes through the extension plate 70 4 drives the positioning column 705 to rotate synchronously, the tension of the spring 707 is overcome and becomes longer, and then it breaks away from the limiting hole 706. When the positioning column 705 moves to correspond to the position of another limiting hole 706, the stretched positioning column 705 can drive the positioning column 705 to enter the other limiting hole 706. At this time, the operation can be stopped, and the positions of the two sealing plates 703 installed on both sides of the connecting frame 702 will be swapped. Finally, the new MBR membrane can be driven into the interior of the treatment tank 2 again, and there is enough time to replace or clean the old MBR membrane.
