[0002] MBR (Membrane Bioreactor) technology is a novel wastewater treatment technology that combines traditional biological treatment with membrane separation technology. In MBR technology, the membrane module plays a crucial role, and its performance directly affects the overall system's treatment efficiency and operational stability. Currently, hollow fiber flat-sheet membranes in MBR technology require mounting brackets for support to ensure they can withstand external forces during use while maintaining structural stability and durability.

[0003] In existing technologies, traditional outlet pipe connection installation structures are difficult to assemble and disassemble quickly. Multiple hoses need to be connected to the outlet pipe at the top of the hollow fiber flat membrane in sequence. Moreover, when fixing the hollow fiber flat membrane, a large number of fasteners are required, such as installation guides, front and rear limiters at the top, and locking bolts, making it difficult to achieve quick assembly and disassembly. Therefore, we propose a hollow fiber flat membrane mounting frame to solve the above problems. Utility Model Content

The aeration pipes 2 are made of PVC material and have aeration holes evenly distributed on their walls. Four hollow support brackets 3 are fixedly connected to the top of the base frame 1. The inner cavity of each support bracket 3 can be filled with cushioning foam to reduce the impact of vibration on the membrane module. A first shaped plate 4 is fixedly connected between the four support brackets 3, and a second shaped plate 5 is placed on top of the four support brackets 3. Multiple partition plates 6 are fixedly connected to the top of the first shaped plate 4 and the inner wall of the second shaped plate 5. Multiple hollow fiber flat membrane bodies 7 are placed between the partition plates 6. The second shaped plate 5 and the first shaped plate 4 cooperate to form installation spaces for the multiple hollow fiber flat membrane bodies 7.

[0023] A pressure plate 8 is placed on the top of the second forming plate 5. Four rectangular columns 9 are fixedly connected to the bottom of the second forming plate 5. The inner walls of the four supports 3 are slidably connected to the outer walls of the four rectangular columns 9. The size of the rectangular columns 9 matches the inner cavity of the supports 3. Through holes are opened on the outer walls of the four supports 3 and the four rectangular columns 9. Pins 10 are slidably connected to the inner walls of the through holes. Four through holes are opened on the outer wall of the pressure plate 8. The inner walls of the four through holes are slidably connected to the outer walls of the four pins 10. Wear-resistant bushings are provided on the inner walls of the through holes, forming a slidable connection with the pins 10.

[0024] The top of the pressure plate 8 is provided with a water collection component, which includes a U-shaped connecting plate 11. The top of the pressure plate 8 is fixedly connected to both ends of the U-shaped connecting plate 11. The bottom of the U-shaped connecting plate 11 is uniformly and interconnected with multiple connecting pipes 12 through injection molding. The connecting pipes 12 are made of elastic rubber material and have a sealing ring on the inner wall. The tops of multiple hollow fiber flat membrane bodies 7 are all fixedly interconnected with water outlet pipes. The inner wall of the connecting pipe 12 is squeezed against the outer wall of the water outlet pipe.

[0025] The top of the pressure plate 8 is fixedly connected to two hollow fixed plates 13, and a water collection pipe 14 is fixedly connected between the two fixed plates 13.

The bottom of the multiple hollow fiber flat membrane bodies 7 is placed between the multiple partition plates 6 at the top of the first shaped plate 4. The first shaped plate 4 and the second shaped plate 5 serve to separate and support the multiple hollow fiber flat membrane bodies 7, completing the initial positioning of the multiple hollow fiber flat membrane bodies 7. Finally, the pressure plate 8 is connected with the U-shaped connecting plate. The 11 and the water collection pipe 14 are fitted together on top of the four supports 3 and the second shaped plate 5, limiting their top position. The pressure plate 8 prevents them from moving up and down. The four pins 10 are inserted into the four through holes and the through holes in sequence. Then, the cotter pins are inserted into the holes on the pins 10 to fix their position. When the pressure plate 8 is on top of the second shaped plate 5, the multiple hollow fiber flat membrane bodies 7 are initially limited in the left, right and front and back. When the pressure plate 8 is fitted from top to bottom, the multiple connecting pipes 12 are inserted into the multiple water outlet pipes at the predetermined positions to form the water outlet connection of the hollow fiber flat membrane bodies 7.
