Description

Technical Field

[0001] The utility model relates to the technical field of filtering membrane components, in particular to a filtering membrane component which is easy to fix. Background Art

[0002] Filtration membrane is used to separate and concentrate solutes in treatment solutions. It is also commonly used to separate colloidal suspensions. Its application areas are constantly expanding. Filtration membrane water treatment is a solid-liquid separation technology. It uses membrane pores to filter water and trap impurities in the water without chemical changes. It is a simple treatment technology.

[0003] Existing filter membrane assemblies are all composed of end caps and filter membrane tubes. When the end caps are used to fix the filter membrane tubes, the filter membrane tubes are often inserted into the circular holes of the end caps. The diameter of the circular holes is smaller than the diameter of the filter membrane tubes. Therefore, the filter membrane tubes are fixed. However, since the diameter of the circular holes is smaller than the diameter of the filter membrane tubes, it is more troublesome to insert the filter membrane tubes into the circular holes, which reduces the speed of fixing and is not convenient for replacing and repairing the filter membrane tubes.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-Figure 5 , a filtration membrane assembly that is easy to fix, comprising:

[0025] An upper end cover 1 and a lower end cover 2;

[0026] A fixing assembly, the fixing assembly includes a circular plate 3, a first circular hole 4, a bolt 5, a fixing plate 6, a second circular hole 7 and a filter membrane tube 18. The side walls of the upper end cover 1 and the lower end cover 2 are both penetrated and fixedly connected with the circular plate 3. The side wall of the circular plate 3 is provided with a first circular hole 4. The inner wall of the upper end cover 1 is slidably connected to the fixing plate 6. The side wall of the fixing plate 6 is provided with a second circular hole 7. The upper end cover 1 and the lower end cover 2 are fixed by a plurality of bolts 5. The first circular hole 4 and the second circular hole 7 are both penetrated and slidably connected with the filter membrane tube 18. The diameters of the first circular hole 4 and the second circular hole 7 are both larger than the diameter of the filter membrane tube 18, and the diameter of the second circular hole 7 is larger than the first circular hole 4, so that the filter membrane tube 18 can be better inserted into the first circular hole 4 and the second circular hole 7.

[0027] The fixing assembly also includes a long groove 8, a limiting rod 9, a slider 10, a spring 11, a support plate 12, a slide rod 13, a push plate 14, a mounting block 15, a threaded rod 16, and a fixing hole 17. The inner wall of the upper end cover 1 is symmetrically provided with long grooves 8, the inner wall of the long groove 8 is fixedly connected to the limiting rod 9, and the side wall of the limiting rod 9 is slidably connected to the slider 10.

[0028] A support plate 12 is fixedly connected to the side wall of the slider 10 , and the other end of the support plate 12 is fixedly connected to the side wall of the fixing plate 6 .

[0029] A spring 11 is sleeved on the side wall of the limiting rod 9 , one end of the spring 11 is fixedly connected to the adjacent side wall of the slider 10 , and the other end of the spring 11 is fixedly connected to the adjacent side wall of the long slot 8 .

[0030] A sliding rod 13 is sealed and slidably connected through the side wall of the upper end cover 1. One end of the sliding rod 13 is fixedly connected to the side wall of the fixed plate 6. The other end of the fixed plate 6 is fixedly connected to a push plate 14, so that the sliding rod 13 can be pushed more conveniently.

[0031] Two fixing holes 17 are formed on the side wall of the slide rod 13 . A mounting block 15 is fixedly connected to the side wall of the upper end cover 1 . A threaded rod 16 is threadedly connected to the side wall of the mounting block 15 . One end of the threaded rod 16 is inserted into the adjacent fixing hole 17 .

[0032] In the present invention, when fixing the filter membrane tube 18, the threaded rod 16 is first rotated to make the threaded rod 16 move out of the adjacent fixing hole 17, so that the slide bar 13 can move freely, and then the push plate 14 is pushed, the push plate 14 drives the slide bar 13 to move, the slide bar 13 drives the fixing plate 6 to move, and the fixing plate 6 also drives the second circular hole 7 to move when moving, so that the inside of the second circular hole 7 and the side wall of the filter membrane tube 18 abut against each other, and then the side wall of the filter membrane tube 18 abuts against each other, and then the threaded rod 16 is rotated again, so that the other end of the threaded rod 16 is inserted into the adjacent fixing hole 17, and then the slide bar 13 is limited, so that the slide bar 13 fixes it, so that the filter membrane tube 18 will not slide from the first circular hole 4 to the inside of the second circular hole 7;

[0033] When the fixed plate 6 moves, it will drive the support plate 12 to move, and the support plate 12 will drive the slider 10 to move along the side wall direction of the limiting rod 9. The slider 10 and the inner wall of the long groove 8 slide against each other, so that the slider 10 can limit the movement trajectory of the fixed plate 6. At this time, the slider 10 squeezes the spring 11. When it is necessary to loosen the fixation of the filter membrane tube 18, it is necessary to rotate the threaded rod 16 again. At this time, under the elastic action of the spring 11, the slider 10 quickly moves in the opposite direction of the compression of the spring 11, so that the fixation of the filter membrane tube 18 can be quickly released.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
