Description

Technical Field

[0001] This utility model relates to the field of filter membrane technology, and in particular to a deformation-resistant tubular filter membrane support structure. Background Technology

[0002] Membrane filtration technology refers to membrane separation technology driven by pressure. It is an advanced method of deep water treatment. Under certain pressure, when the raw liquid flows through the membrane surface, the numerous tiny pores on the membrane surface only allow water and small molecules to pass through, becoming the permeate. Meanwhile, substances in the raw liquid with a volume larger than the pore size of the membrane surface are trapped outside the membrane, becoming the concentrate. Thus, the purpose of separating and concentrating the raw liquid is achieved.

[0003] In the existing technology, there are many types of filter membranes, including tubular filter membranes. Most tubular filter membranes are hollow structures with internal support structures to support them. However, traditional support structures can only support tubular filter membranes of fixed specifications and cannot be applied to tubular filter membranes of other specifications, thus reducing the applicability of the support structure.

[0025] To facilitate quick and easy fixation of the support ring 3, each of the two fixing blocks 2 has an internal movable groove 11.

The positioning blocks 14 penetrate the inner wall of the movable groove 11 and extend to the outside of the fixing block 2. The inner wall of each of the two support rings 3 has a positioning groove that is inserted into the positioning block 14.

One end of the spring 16 is fixedly connected to the inner wall of the movable groove 11, and the other end of the spring 16 is fixedly connected to the slide plate 13.

[0026] By setting up membrane body 1, fixing block 2, support ring 3, slider 4, limiting block 5, limiting plate 6, telescopic rod 7, threaded rod 8, rotating block 9, sleeve 10, movable groove 11, sliding rod 12, sliding plate 13, positioning block 14, pulling block 15, and spring 16, the function of supporting tubular filter membranes of different specifications is realized. By replacing the support ring 3 of different sizes, tubular filter membranes of different thicknesses can be supported. By adjusting the distance between the two fixing blocks 2, tubular filter membranes of different lengths can be supported, thus improving the applicability of the support structure.

[0027] The outer surface of the telescopic rod 7 is provided with a reinforcing component, which includes a mounting block 17. The mounting block 17 is fixedly installed on the outer surface of the telescopic rod 7 and the sleeve 10. Two mounting rings 18 are fitted on the outer surface of the mounting block 17. Two mounting plates 19 are fixedly installed on the side wall of the mounting block 17. The inner wall of each of the two mounting rings 18 is provided with a mounting groove for insertion into the mounting plate 19. A connecting plate 20 is fixedly installed on the side wall at both ends of one mounting ring 18. A connecting groove for insertion into the connecting plate 20 is provided on the side wall at both ends of the other mounting ring 18. A fixing bolt 21 is threadedly connected to the upper surface of the mounting ring 18. Two fixing plates 22 are fixedly installed on both sides of the two mounting rings 18. A telescopic sleeve 23 is fitted on the outer surface of the fixing plate 22. A positioning bolt 24 is threadedly connected to the outer surface of the telescopic sleeve 23. The fixing bolt 21 passes through the mounting ring 18 and is inserted into the mounting plate 19.

[0028] By setting up mounting block 17, mounting ring 18, mounting plate 19, connecting plate 20, fixing bolt 21, fixing plate 22, telescopic sleeve 23 and positioning bolt 24, the function of supporting the interior of the tubular filter membrane in the middle position is realized. By setting up mounting ring 18 and telescopic sleeve 23 that are attached to the inner wall of the tubular filter membrane, the inner wall of the membrane body 1 in the middle position is supported, thereby improving the support effect of the tubular filter membrane.

[0029] Working principle: When supporting the tubular filter membrane, first, place two mounting rings with the same diameter as the inner wall of the membrane body 1 and equipped with fixing plates 22 and telescopic sleeves 23 close to the mounting block 17 on the outer surface of the telescopic rod 7, so that the mounting plate 19 on the side wall of the mounting block 17 is aligned with the mounting groove on the side wall of the mounting ring 18, and the connecting plate 20 is aligned with the connecting groove. Then, move the two mounting rings 18 so that the mounting plate 19 is inserted into the mounting groove. When both mounting rings 18 are in contact with the outer wall of the mounting block 17, the two mounting rings 18 contact each other, and the connecting plate 20 is inserted into the connecting groove. Then, tighten the two fixing bolts 2. 1. The fixing bolt 21 passes through the mounting ring 18 and the mounting plate 19, and the mounting ring 18 is fixed by the mounting plate 19. Then, the positioning bolt 24 is turned so that the positioning bolt 24 extends away from the telescopic sleeve 23. When the positioning bolt 24 slides out from the inside of the positioning hole, the restriction on the telescopic sleeve 23 is released. Then, the telescopic sleeve 23 is pulled according to the length of the membrane body 1 so that the telescopic sleeve 23 slides on the outer surface of the fixing plate 22. When the telescopic sleeve 23 slides out a suitable length, the positioning bolt 24 is turned in the opposite direction so that the positioning bolt re-turns into the inside of the positioning hole and fixes the telescopic sleeve 23.

[0030] Next, bring the support ring 3, which has the same diameter as the inner wall of the membrane 1, close to the fixing block 2, so that the limiting block 5 is aligned with the limiting groove. At the same time, pull the pull block 15, so that the pull block 15 drives the positioning block 14 to move inside the movable groove 11. At the same time, the slide plate 13 slides on the outer surface of the slide rod 12, and the spring 16 is compressed and deformed. After the positioning block 15 retracts into the movable groove 11, move the support ring 3 and slide it on the outer surface of the fixing block 2. The limiting block 5 slides inside the limiting groove. After the support ring 3 is fitted onto the outer surface of the fixing block 2, the limiting plate 6 slides into the slot. Then release the pull block 15, the spring 16 returns to its original state, push the slide plate 13 to slide on the outer surface of the slide rod 12, and push the positioning block 14 to move, so that the positioning block 14 moves from the depth inside the movable groove 11 and inserts into the positioning groove of the inner wall of the support ring 3 to fix the support ring 3. Repeat the above operation to fix the other support ring 3.

[0031] Next, align the support structure with the membrane 1, so that the slider 4 is aligned with the groove. Move the support structure to slide into the membrane 1, so that the slider 4 slides inside the groove. After the support structure slides into the membrane 1, rotate the rotating block 9. When the rotating block 9 rotates, it drives the threaded rod 8 to rotate. When the threaded rod 8 rotates, it drives the sleeve 10 to move through the threaded groove. Under the action of the telescopic rod 7, the distance between the two fixed blocks 2 is extended or shortened. When the two support rings 3 contact the inner walls at both ends of the membrane 1, they support the two ends of the membrane 1. At the same time, the mounting ring 18 and telescopic sleeve 23 on the outer surface of the telescopic rod 7 are attached to the inner wall at the middle position of the membrane 1, thus completing the overall support of the membrane 1.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
