However, traditional hollow fiber membrane modules often have the problem of fixed volume and cannot be flexibly adjusted according to actual needs. This limitation restricts their adaptability and flexibility in different application scenarios and makes it difficult to meet the diverse and complex market needs.

[0038] In the present embodiment, the design of the frame mechanism 1 facilitates the smooth fixation of the hollow fiber membrane mechanism 2, thereby achieving the fixation of the hollow fiber membrane body 21, wherein the design of the first support frame 11 and the second support frame 12 facilitates the installation of hollow fiber membrane mechanisms 2 of different widths, and the design of the first side tube 221, the second side tube 222 and the middle tube 223 can adjust the width of the hollow fiber membrane mechanism 2 by increasing or decreasing the number of the middle tubes 223, so that the volume of the membrane assembly can be flexibly adjusted according to the needs of the actual application scenario, whether it is processing a large flow rate or a small flow rate of liquid, the staff can easily achieve the matching of the processing capacity by increasing or decreasing the number of the middle tubes 223, this high flexibility enables the membrane assembly to be widely used in water treatment and industrial separation processes of various scales and complexities, significantly improving the adaptability and versatility of the equipment, during operation, the staff first shakes the crank 117, thereby driving one of the screw rods 112 to rotate, at this time, on the first synchronous wheel 11 3. The design of the first synchronous belt 114, the second synchronous wheel 116 and the second synchronous belt 115 allows them to rotate synchronously with the three screw rods 112. When the four screw rods 112 rotate at the same time, the sliding rod 121 on the second support frame 12 will telescope in the sleeve 111 on the first support frame 11, so as to adjust the distance between the first support frame 11 and the second support frame 12. This design can not only accurately adjust the distance between the first support frame 11 and the second support frame 12, but also when the screw rod 112 stops rotating, the sliding rod 121 on the second support frame 12 will not extend into the sleeve 111 due to external force, thereby improving the stability of the frame mechanism 1. The design of the synchronous rotation of the four screw rods 112 makes the distance between the first support frame 11 and the second support frame 12 more stable during the adjustment process, and there will be no shaking or jamming. By adjusting the distance between the first support frame 11 and the second support frame 12, hollow fiber membrane mechanisms 2 of different widths can be smoothly installed in the frame mechanism 1.

[0039] like Figures 6 to 8 As shown, the first side tube 221 is located at one end of the middle tube 223 and the middle tube 223 is located at one end of the second side tube 222. Both are provided with a first mounting head 224. The middle tube 223 is located at one end of the first side tube 221 and the second side tube 222 is located at one end of the middle tube 223. Both are provided with a second mounting head 225. The first mounting head 224 is slidably connected with the second mounting head 225.

[0040] In this embodiment, the design of the first mounting head 224 and the second mounting head 225 allows the middle tube 223 to be quickly assembled with the first side tube 221 and the second side tube 222. When in use, the width of the hollow fiber membrane mechanism 2 is adjusted by increasing or decreasing the number of the middle tubes 223, wherein the number of the middle tubes 223 can be zero, that is, the first side tube 221 and the second side tube 222 are directly spliced ​​together.

[0041] like Figures 9 and 10 As shown, grooves 2251 are respectively provided at both ends of the side wall of the second mounting head 225, and a limit spring 2252 is fixedly connected in the groove 2251. One end of the limit spring 2252 is fixedly connected to a limit block 2253, and the limit block 2253 is slidably connected to the groove 2251. Limit holes 2241 are respectively provided at both ends of the side wall of the first mounting head 224, and the limit block 2253 is movably connected to the limit hole 2241. The limit block 2253 is located at one end of the first mounting head 224 and has an arc surface; the first mounting head 22 The side wall is located at both ends of the limiting hole 2241 and is fixedly connected to the first springs 2242 respectively. The two first springs 2242 are commonly fixedly connected to a connecting plate 2243. A push rod 2244 is fixedly connected to the middle of the connecting plate 2243. One end of the push rod 2244 extends to the inside of the limiting hole 2241 and is fixedly connected to a push plate 2245. The first mounting head 224 is located in the first spring 2242 and is fixedly connected to a first telescopic rod 2246. The first telescopic rod 2246 is fixedly connected to the connecting plate 2243.

[0042] In this embodiment, the design of the limit spring 2252 and the limit block 2253 allows the second mounting head 225 to change its position along the inner wall of the first mounting head 224 during the process of being installed inside the first mounting head 224. When the limit block 2253 just contacts the first mounting head 224, the limit block 2253 will retract into the groove 2251 due to the push of its own curved surface and external force. At this time, the limit spring 2252 will shrink. When the limit block 2253 moves to the position of the limit hole 2241 on the first mounting head 224, the limit block 2253 will move into the limit block 2253 under the thrust of the limit spring 2252, thereby allowing the second mounting head 225 to be stably fixed in the first mounting head 224. In addition, the design of the connecting plate 2243, the push rod 2244 and the push plate 2245 allows the worker to It is more convenient for the operator to disassemble the first mounting head 224 and the second mounting head 225. During the operation, they only need to press the two connecting plates 2243 at the same time, thereby driving the two push plates 2245 to move, and then push the limit block 2253 into the groove 2251. In this way, the first mounting head 224 and the second mounting head 225 can be smoothly disassembled. The design of the first spring 2242 can push the connecting plate 2243. When the second mounting head 225 is disassembled, the operator will loosen the two connecting plates 2243. At this time, the first spring 2242 will rebound, thereby pushing the connecting plate 2243 to move, and then driving the push plate 2245 to move, so as to reset the push plate 2245, so that the limit block 2253 can enter the limit hole 2241 more smoothly when the second mounting head 225 is installed later.

[0043] like Figures 2 to 5 As shown, rollers 13 are installed at both ends of the bottom of the first support frame 11 and the second support frame 12, and slots 14 are respectively provided at the upper and lower ends of the first support frame 11 and the second support frame 12, and blocks 24 are respectively provided at both ends of the assembled conduit 22, and the blocks 24 are movably connected with the slots 14;

[0044] In this embodiment, the design of the roller 13 makes it easier to adjust the distance between the first support frame 11 and the second support frame 12, and the design of the clamping block 24 and the clamping slot 14 allows the hollow fiber membrane mechanism 2 to be smoothly installed in the frame mechanism 1.

[0045] like Figure 6 to Figure 7 As shown, the first side tube 221 and the second side tube 222 are both fixedly connected to the second spring 25 at one end away from the middle tube 223, and one end of the second spring 25 is fixedly connected to the clamping block 24, and one end of the clamping block 24 is fixedly connected to the pressing block 26; the first side tube 221 and the second side tube 222 are both fixedly connected to the second telescopic rod 27 in the second spring 25, and the second telescopic rod 27 is fixedly connected to the clamping block 24;

[0046] In this embodiment, when installing the hollow fiber membrane mechanism 2, the pressure blocks 26 on the first side tube 221 and the second side tube 222 in the assembled conduit 22 are first pressed at the same time, thereby driving the two clamping blocks 24 to move and reducing the distance between the two clamping blocks 24. In this way, the assembled conduit 22 can be moved between the first support frame 11 and the second support frame 12. When the clamping block 24 moves to the position of the clamping slot 14, the pressure block 26 is released, and the second spring 25 will rebound quickly, thereby pushing the clamping block 24 into the clamping slot 14, thereby realizing the installation of the assembled conduit 22, thereby realizing the installation of the hollow fiber membrane mechanism 2.

[0047] Working principle: Through the design of the first side tube 221, the second side tube 222 and the middle tube 223, the width of the hollow fiber membrane structure 2 can be adjusted by increasing or decreasing the number of the middle tubes 223, so that the volume of the membrane component can be flexibly adjusted according to the needs of the actual application scenario. Whether it is processing a large flow rate or a small flow rate of liquid, the staff can easily achieve matching of the processing capacity by increasing or decreasing the number of the middle tubes 223. This high degree of flexibility enables the membrane component to be widely used in water treatment and industrial separation processes of various scales and complexities, significantly improving the adaptability and versatility of the equipment. Through the design of the limit spring 2252 and the limit block 2253, the second mounting head 225 is installed in the process of being installed inside the first mounting head 224. 224, the second mounting head 225 can be stably fixed in the first mounting head 224. In addition, the design of the connecting plate 2243, the push rod 2244 and the push plate 2245 makes it easier for the staff to disassemble the first mounting head 224 and the second mounting head 225. When the second mounting head 225 is removed, the staff will release the two connecting plates 2243. At this time, the first spring 2242 will rebound, thereby pushing the connecting plate 2243 to move, and then driving the push plate 2245 to move, so that the push plate 2245 can be reset, so that the limit block 2253 can enter the limit hole 2241 more smoothly when the second mounting head 225 is installed later. This method is used to realize the disassembly, assembly and increase and decrease of the intermediate tube 223. After the width of the hollow fiber membrane mechanism 2 is adjusted, it is necessary to adjust the distance between the first support frame 11 and the second support frame 12. During operation, the staff first shakes the crank 117 to drive one of the screw rods 112 to rotate. At this time, the design of the first synchronous wheel 113, the first synchronous belt 114, the second synchronous wheel 116 and the second synchronous belt 115 allows them to rotate synchronously with the three screw rods 112. When the four screw rods 112 rotate at the same time, the sliding rod 121 on the second support frame 12 will telescope in the sleeve 111 on the first support frame 11, so as to adjust the distance between the first support frame 11 and the second support frame 12. When installing the hollow fiber membrane mechanism 2,First, the pressing blocks 26 on the first side tube 221 and the second side tube 222 in the assembled conduit 22 are pressed simultaneously, thereby driving the two clamping blocks 24 to move, so that the distance between the two clamping blocks 24 is reduced, so that the assembled conduit 22 can be moved between the first support frame 11 and the second support frame 12. When the clamping block 24 moves to the position of the clamping slot 14, the pressing block 26 is released, and the second spring 25 will rebound quickly, thereby pushing the clamping block 24 into the clamping slot 14, thereby realizing the installation of the assembled conduit 22, thereby realizing the installation of the hollow fiber membrane mechanism 2.
