Description

Technical Field

[0001] This utility model relates to the field of hollow fiber flat film installation technology, and in particular to an installation frame. Background Technology

[0002] Hollow fiber flat sheet membranes are a type of high-efficiency separation membrane material that combines the advantages of both hollow fiber membranes and flat sheet membranes, possessing high specific surface area and good mechanical strength. Its structure consists of numerous hollow fiber filaments, with hollow channels inside the fibers and a flat sheet membrane layer on the outside, forming a compact filtration unit. This type of membrane is widely used in water treatment, biomedicine, food industry, and other fields, effectively separating suspended solids, microorganisms, and macromolecules. Its characteristics include high flux, strong antifouling properties, long service life, and ease of cleaning and maintenance.

[0003] A search revealed that patent CN214880485U discloses an installation frame for hollow fiber flat sheet membranes, which uses an upper bracket and a lower bracket to fix the top and bottom of the hollow fiber flat sheet membrane respectively, thereby expanding the hollow fiber flat sheet membrane.

[0004] However, the above-mentioned device has the following drawbacks: the vertical height and horizontal span of the bracket are both fixed, making it impossible to install hollow fiber flat films of different heights and widths, resulting in poor versatility and flexibility of the mounting bracket. Therefore, further improvements are needed, and to this end, we propose a mounting bracket. Utility Model Content

[0008] Furthermore, the second slot has a through hole at the top, and the extrusion assembly includes a U-shaped plate fixed to the upper surface of the top plate. A horizontal plate is horizontally arranged inside the U-shaped plate. A pressure rod is fixed on the lower surface of the horizontal plate above each through hole. The pressure rod passes through the through hole and is slidably connected to the through hole. An extrusion screw is threaded through the middle of the top of the U-shaped plate, and the bottom end of the extrusion screw contacts the upper surface of the horizontal plate.

[0009] Furthermore, tension springs are fixedly connected to both sides of the upper surface of the horizontal plate and the inner top wall of the U-shaped plate.

[0010] Furthermore, the connecting assembly includes a square tube, and a crossbar is slidably connected inside both ends of the square tube.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4 As shown, a mounting bracket is disclosed, comprising two sets of side support structures. Each set of side support structures includes a base plate 1, a top plate 2, and two support components 5. The upper surface of the base plate 1 is provided with a plurality of first slots 3 at equal intervals, and the lower surface of the top plate 2 is provided with a plurality of second slots 4 at equal intervals. The bottom ends of the two support components 5 are fixedly connected to the base plate 1, and the top ends of the two support components 5 are fixedly connected to the lower surface of the top plate 2. A pressing component 6 is installed on the upper surface of the top plate 2. The bottom of the two sets of side support structures is fixedly connected to two detachable connecting components 7. The surface of the base plate 1 of the two sets of side support structures is fixed with positioning sleeves 8 for installing the connecting components 7.

[0024] The support assembly 5 includes a vertical tube 51 fixed to the upper surface of the base plate 1, a vertical rod 52 slidably connected inside the vertical tube 51, the top end of the vertical rod 52 being fixedly connected to the lower surface of the top plate 2, and a first locking bolt 53 being threadedly connected through the side wall of the top end of the vertical tube 51.

[0025] By moving the vertical rod 52 up and down along the vertical tube 51, the distance between the bottom plate 1 and the top plate 2 can be adjusted, which facilitates the installation of hollow fiber flat membranes 9 at different heights. After adjustment, tighten the first locking bolt 53 to press and fix the vertical rod 52. During installation, insert the bottom of the hollow fiber flat membrane 9 into the first slot 3 on the surface of the bottom plate 1, and insert the top of the hollow fiber flat membrane 9 into the second slot 4 on the lower surface of the top plate 2. The first slot 3, the second slot 4, and the bottom and top of the hollow fiber flat membrane 9 are all trapezoidal designs.

[0026] The second slot 4 has a through hole 41 at the top. The extrusion assembly 6 includes a U-shaped plate 61 fixed to the upper surface of the top plate 2. A horizontal plate 62 is horizontally arranged inside the U-shaped plate 61. A pressure rod 63 is fixed on the lower surface of the horizontal plate 62 and above each through hole 41. The pressure rod 63 passes through the through hole 41 and is slidably connected to the through hole 41. An extrusion screw 64 is threaded through the middle of the top of the U-shaped plate 61. The bottom end of the extrusion screw 64 contacts the upper surface of the horizontal plate 62.

[0027] Once the top of the hollow fiber flat sheet membrane 9 is inserted into the second slot 4, the extrusion screw 64 is turned down. The extrusion screw 64 will press the horizontal plate 62, causing the horizontal plate 62 to drive the pressure rod 63 down. The pressure rod 63 is used to press the hollow fiber flat sheet membrane 9, thereby fixing the hollow fiber flat sheet membrane 9.

[0028] Tension springs 65 are fixedly connected to both sides of the upper surface of the horizontal plate 62 and the inner top wall of the U-shaped plate 61.

[0029] When the hollow fiber flat sheet membrane 9 needs to be disassembled and replaced, the extrusion screw 64 is turned in the opposite direction, causing the extrusion screw 64 to move upward. The tension spring 65 will then pull the horizontal plate 62 and the pressure rod 63 upward to reset, and then the hollow fiber flat sheet membrane 9 can be pulled out from the second slot 4.

[0030] The connecting component 7 includes a square tube 71, and a crossbar 72 is slidably connected to both ends of the square tube 71. The end of the crossbar 72 away from the square tube 71 is inserted into the positioning sleeve 8 on the corresponding side. A groove 74 is formed on the upper surface of the end of the crossbar 72 located inside the positioning sleeve 8. A spring 75 is fixed to the bottom wall of the groove 74, and a locking rod 76 is fixed to the top of the spring 75. A locking hole 81 for locking the locking rod 76 is formed on the top wall of the positioning sleeve 8.

[0031] The square tube 71 has two end sidewalls that are both through and connected by a second locking bolt 73 via a thread.

[0032] After the height of the side support structure is adjusted, the connecting component 7 can be installed between the two side support structures, and the horizontal bar 72 can be adjusted to slide in the square tube 71 to adjust the length of the connecting component 7. After adjustment, tighten the second locking bolt 73 to press and fix the horizontal bar 72. Then, press the locking rod 76 on the horizontal bar 72 so that the locking rod 76 retracts into the groove 74. Then insert the horizontal bar 72 into the positioning sleeve 8 on the surface of the base plate 1. Then, under the pressure of the spring 75, the locking rod 76 is inserted into the locking hole 81 to achieve a fixed connection between the horizontal bar 72 and the base plate 1. Then connect the other end of the horizontal bar 72 to the positioning sleeve 8 on the surface of the other base plate 1. In this way, the two side support structures are laterally opened by the connecting component 7 so as to open and fix the hollow fiber flat film 9 of different widths.

[0033] When not in use or during transportation, the connecting assembly 7 can be disassembled from the two side support structures. To disassemble, squeeze the clamping rod 76 to separate it from the clamping hole 81, and then pull the crossbar 72 out of the positioning sleeve 8. The disassembled assembly is smaller in size and more convenient to transport.

[0034] Working principle: First, adjust the distance between the bottom plate 1 and the top plate 2 by adjusting the length of the support component 5. After both side support structures are adjusted, install the connecting component 7 between the two side support structures and adjust the length of the connecting component 7. Then, insert the bottom of the hollow fiber flat sheet membrane 9 into the first slot 3 on the surface of the two bottom plates 1, and insert the top of the hollow fiber flat sheet membrane 9 into the second slot 4 on the lower surface of the two top plates 2. Finally, turn the extrusion screw 64 above each top plate 2. Use the extrusion screw 64 to drive the horizontal plate 62 and the pressure rod 63 to descend, thereby extruding and fixing the top of the hollow fiber flat sheet membrane 9.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
