Description

Technical Field

[0001] This utility model relates to the field of hollow fiber component technology, and in particular to a hollow fiber membrane column that is easy to assemble and disassemble. Background Technology

[0002] In a hollow fiber column membrane module, the membrane fibers are fixed on the water distribution separators at both ends of the hollow fiber column membrane module. Then, the two ends of the hollow fiber column membrane module are end-sealed with resin to form resin end faces. This allows the feed solution to enter the inner cavity of the membrane module through one end of the hollow fiber column membrane module and be filtered by the membrane fibers. The filtered concentrate is discharged from the concentrate port of the hollow fiber column membrane module, while the permeate, i.e., the product water, flows out from the product water port.

[0003] After use, existing hollow fiber membrane modules need to be replaced. Since hollow fiber membrane modules come in sets, a whole set needs to be replaced during replacement. Replacing a single module is inefficient. Therefore, there is an urgent need for a hollow fiber membrane module that is easy to disassemble and assemble. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a hollow fiber membrane column that is easy to disassemble and assemble, which can solve the problem that hollow fiber membrane columns are inconvenient to disassemble and assemble.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a hollow fiber membrane column that is easy to assemble and disassemble, comprising a hollow fiber membrane column and a fiber membrane column support, wherein an inlet pipe is fixedly connected to the upper end of the hollow fiber membrane column and an outlet pipe is fixedly connected to the lower end of the hollow fiber membrane column;

[0006] The fixing mechanism is located inside the fiber membrane column support;

[0007] The disassembly and assembly mechanism is located on the outer surface of the hollow fiber membrane column. The disassembly and assembly mechanism includes two fixing blocks, which are fixedly connected to the outer surface of the hollow fiber membrane column. Two sliding grooves are opened on the outer surface of each of the two fixing blocks. Springs are fixedly connected to the inner walls of the four sliding grooves. Limit blocks are fixedly connected to the ends of the four springs away from the sliding grooves. One end of the limit block is arc-shaped.

[0008] Preferably, the outer surface of the fiber membrane column support is fixedly connected with multiple sets of fixing plates, with each set of two fixing plates forming a group, and the multiple sets of fixing plates are slidably connected to the corresponding fixing blocks;

[0009] The outer surface of the fixed clamp is provided with a groove that matches the limiting block, and the outer surface of the fiber membrane column support is provided with a threaded groove, with a bolt threaded inside the threaded groove.

[0010] Preferably, the fixing mechanism includes a threaded rod, which is rotatably connected inside the fiber membrane column support. The outer surface of the threaded rod has multiple sets of bidirectional threads, and one end of the threaded rod has a groove. A fixing plate is fixedly connected to the inner wall of the groove, and the thread groove is in contact with the outer surface of the threaded rod.

[0011] Preferably, the inner wall of the bolt is provided with a groove that matches the fixing plate, and the bolt is slidably connected to the fixing plate;

[0012] When a bolt is threaded into a threaded groove, the bolt can make tight contact with the threaded rod and limit its movement.

[0013] Preferably, each of the multiple sets of threads on the threaded rod is fixedly connected to a mounting plate, with each set of two mounting plates forming a group. Each set of mounting plates has a fixed mounting plate fixedly connected to its outer surface, and each fixed mounting plate has a rubber pad fixedly connected to its outer surface.

[0014] Preferably, the upper and lower ends of the multiple sets of mounting plates are slidably connected to the fiber membrane column support, and the rubber pads are in contact with the hollow fiber membrane column.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) The hollow fiber membrane column that is easy to disassemble and assemble has a mounting plate that moves in the opposite direction, which causes the fixed mounting plate to move. The movement of the fixed mounting plate causes the rubber pad to move, so that the rubber pad moves away from the hollow fiber membrane column, making it easy to disassemble the hollow fiber membrane column. The use of this device can effectively fix the hollow fiber membrane column, increasing its practicality. At the same time, the device can quickly replace multiple sets of hollow fiber membrane columns, increasing its convenience.

[0017] (2) The hollow fiber membrane column is easy to install and disassemble. The spring resets the spring and drives the corresponding limit block to move into the inside of the fixed clamp for simple support and fixation. When disassembly is required, simply place your hand on the inlet and outlet pipes and pull outwards. This device is convenient for installing and disassembling the hollow fiber membrane column, making it easy to use. It can also be easily fixed, which facilitates subsequent fastening and installation of external pipes at the inlet and outlet pipes, increasing its practicality.

[0018] (3) The hollow fiber membrane column is easy to disassemble and assemble. After the hollow fiber membrane column is replaced, it is connected to the threaded groove by bolts, so that the bolts contact and fix the threaded rod. This can effectively fix the threaded rod and prevent the fixed hollow fiber membrane column from loosening due to the rotation of the threaded rod caused by external reasons, thus increasing its practicality.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0030] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0031] Please see Figure 1-6 This utility model provides a technical solution: a hollow fiber membrane column that is easy to assemble and disassemble, including a hollow fiber membrane column 1 and a fiber membrane column support 2. The upper end of the hollow fiber membrane column 1 is fixedly connected to a water inlet pipe 3, and the lower end of the hollow fiber membrane column 1 is fixedly connected to a water outlet pipe 4.

[0032] The fixing mechanism is located inside the fiber membrane column support 2;

[0033] The disassembly and assembly mechanism is located on the outer surface of the hollow fiber membrane column 1. The disassembly and assembly mechanism includes two fixing blocks 5, which are fixedly connected to the outer surface of the hollow fiber membrane column 1. Two sliding grooves 6 are opened on the outer surface of each of the two fixing blocks 5. Springs 7 are fixedly connected to the inner walls of the four sliding grooves 6. Limiting blocks 8 are fixedly connected to the ends of the four springs 7 away from the sliding grooves 6. One end of the limiting block 8 is arc-shaped.

[0034] Furthermore, multiple sets of fixing plates 9 are fixedly connected to the outer surface of the fiber membrane column support 2. Each set of fixing plates 9 consists of two plates. The multiple sets of fixing plates 9 are slidably connected to the corresponding fixing blocks 5. The outer surface of the fixing plates 9 is provided with grooves that are compatible with the limiting blocks 8. The outer surface of the fiber membrane column support 2 is provided with threaded grooves 10. Bolts 14 are threaded into the inner threads of the threaded grooves 10.

[0035] Furthermore, the fixing mechanism includes a threaded rod 11, which is rotatably connected inside the fiber membrane column support 2. The outer surface of the threaded rod 11 has multiple sets of bidirectional threads. One end of the threaded rod 11 has a groove 12, and a fixing plate 13 is fixedly connected to the inner wall of the groove 12. The inner wall of the bolt 14 has a groove that matches the fixing plate 13. The bolt 14 is slidably connected to the fixing plate 13. The threaded groove 10 is in contact with the outer surface of the threaded rod 11. When the bolt 14 is threadedly connected to the threaded groove 10, the bolt 14 can make tight contact with the threaded rod 11 and limit the threaded rod 11.

[0036] Furthermore, mounting plates 15 are fixedly connected to multiple sets of threads on the threaded rod 11. Each set of mounting plates 15 consists of two plates. Fixed mounting plates 16 are fixedly connected to the outer surfaces of the multiple sets of mounting plates 15. The upper and lower ends of the multiple sets of mounting plates 15 are slidably connected to the fiber membrane column support 2. Rubber pads 17 are fixedly connected to the outer surfaces of the fixed mounting plates 16. The rubber pads 17 are in contact with the hollow fiber membrane column 1.

[0037] Furthermore, when using this device, if it is necessary to quickly disassemble and replace the hollow fiber membrane column 1, first unscrew the bolt 14 from the threaded groove 10. The bolt 14 slides into the groove 12, so that the groove in the bolt 14 connects with the fixing plate 13. Then rotate the bolt 14. The rotation of the bolt 14 drives the threaded rod 11 to rotate. The rotation of the threaded rod 11 drives the mounting plate 15 to slide. Each set of mounting plates 15 moves relative to or opposite to each other. The opposite displacement of the mounting plates 15 drives the fixed mounting plate 16 to move. The movement of the fixed mounting plate 16 drives the rubber pad 17 to move. After the rubber pad 17 moves away from the hollow fiber membrane column 1, it is convenient to disassemble the hollow fiber membrane column. The use of this device can effectively fix the hollow fiber membrane column 1, increasing its practicality. At the same time, this device can quickly replace multiple sets of hollow fiber membrane columns 1, increasing its convenience.

[0038] Furthermore, when using this device, if the hollow fiber membrane column 1 needs to be installed, first align the fixing block 5 with the fixing clamp 9, and manually press the inlet pipe 3 and outlet pipe 4 so that the limiting block 8 contacts the fixed clamp 9 with its arc surface, causing the limiting block 8 to slide and compress the spring 7. At this time, the hollow fiber membrane column 1 slides. When the limiting block 8 slides to the groove position inside the fixing clamp 9, the spring 7 resets and moves the corresponding limiting block 8 to the inside of the fixing clamp 9 for simple support and fixation. When disassembly is required, simply place your hand on the inlet pipe 3 and outlet pipe 4 and pull outwards. This device is convenient for installing and disassembling the hollow fiber membrane column 1, making it easy to use. It also provides simple fixation, facilitating subsequent tightening and installation of external pipes at the inlet pipe 3 and outlet pipe 4, thus increasing its practicality.

[0039] Furthermore, after the hollow fiber membrane column 1 is replaced, it is connected to the threaded groove 10 by bolt 14, so that bolt 14 contacts and fixes the threaded rod 11. This can effectively fix the threaded rod 11 and prevent the fixed hollow fiber membrane column 1 from loosening due to rotation of the threaded rod 11 caused by external factors, thus increasing its practicality.

[0040] Working Principle: When using this device, if quick disassembly and replacement of the hollow fiber membrane column 1 is required, first unscrew the bolt 14 from the threaded groove 10. The bolt 14 slides into the groove 12, connecting the groove in the bolt 14 with the fixing plate 13. Then, rotate the bolt 14. The rotation of the bolt 14 drives the threaded rod 11 to rotate, which in turn drives the mounting plate 15 to slide. Each set of mounting plates 15 moves relative to or opposite to each other. The opposite displacement of the mounting plates 15 drives the fixed mounting plate 16 to move. The movement of the fixed mounting plate 16 moves the rubber pad 17, moving the rubber pad 17 away from the hollow fiber membrane column 1, facilitating the disassembly of the hollow fiber membrane column. When installing the hollow fiber membrane column 1, first align the fixing block 5 with the fixing clamp 9, and manually press the inlet pipe 3 and outlet pipe 4 so that the limiting block 8 contacts the arc surface of the limiting block 8 under the limitation of the fixing clamp 9, causing the limiting block 8 to slide and compress the spring 7. At this time, the hollow fiber membrane column 1 slides. When the limiting block 8 slides to the groove position inside the fixing clamp 9, the spring 7 resets and drives the corresponding limiting block 8 to move into the interior of the fixing clamp 9 for simple support and fixation. When disassembly is required, simply place your hand on the inlet pipe 3 and outlet pipe 4 and pull outwards. This device is convenient for installing and disassembling the hollow fiber membrane column 1.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
