Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, specifically a hollow fiber special iron frame. Background Technology

[0002] Hollow fiber components are a novel type of fiber material composed of multiple layers of hollow cellulose or minerals. This material features low density, high specific surface area, and high porosity, making it widely used in filtration, separation, and adsorption. Over the past few decades, hollow fiber components have been extensively applied in numerous fields, including biomedicine, food and beverage, environmental protection, and chemical engineering. For example, in the biomedical field, hollow fiber components are used in the preparation of biopharmaceutical products and bioreactors.

[0003] Existing supports for fixing hollow fiber components consist of multiple brackets, including brackets for fixing hollow fiber tubes / columns, brackets for fixing inlet hoses, and brackets for fixing waste hoses and permeate hoses. Each bracket is mounted on the experimental table via a base, which is inconvenient for installation and transportation. After the experiment, the presence of multiple bases makes cleaning difficult, and the bases occupy a significant amount of experimental table space, thus affecting the placement of liquid containers and peristaltic pumps. Existing hoses are usually not fixed or are simply fixed with a band. When the hose is not fixed, its weight increases after the solution enters, causing the hose to drag and deform at the hose interface, affecting the liquid flow efficiency. Fixing with a band can also cause hose deformation if it is too tight, or affect the fixing effect if it is too loose, and it is also inconvenient to disassemble. Therefore, we propose a special iron frame for hollow fiber. Utility Model Content

[0004] The purpose of this utility model is to provide a special iron frame for hollow fiber to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hollow fiber special iron frame, including an upright, a support assembly on the outer wall of the upright, the support assembly including a C-shaped sleeve slidably connected to the outer wall of the upright, a crossbar fixedly connected to the outer wall of the C-shaped sleeve with a notch, the end of the crossbar near the C-shaped sleeve and the notch of the C-shaped sleeve together forming a spacer groove, an internally threaded fastening sleeve threadedly connected to the outer wall of the end of the crossbar near the upright, a sliding groove distributed along the length of the crossbar on the outer wall of the crossbar, and the sliding groove completely penetrating the crossbar, an internally threaded sleeve threadedly connected to the outer wall of the end of the crossbar away from the upright, a retaining sleeve fixedly connected to the end of the internally threaded sleeve away from the upright, and the inner diameter of the retaining sleeve being larger than the inner diameter of the internally threaded sleeve, and a deformation assembly for extension and bending provided at the end of the crossbar away from the upright.

[0006] Preferably, the deformable component includes a fixed shaft hinged in the groove, a stop rod fixedly connected to the side surface of the fixed shaft, a folding rod fixedly connected to one end of the stop rod, and a wire retainer for limiting the hose is provided on both the folding rod and the crossbar.

[0007] Preferably, the cable fastener includes a movable sleeve that is slidably connected to the crossbar and the folding bar respectively, a limit hook is fixedly connected to the outer wall of the movable sleeve, and a first fastening button is threadedly connected to the side of the movable sleeve away from the limit hook.

[0008] Preferably, a sleeve is slidably connected to the outer wall of the upright, and a spring is fixedly connected to the outer wall of the sleeve. The spring clamps the hollow fiber column through elastic deformation. A second fastening button is threadedly connected to the side of the sleeve away from the spring, and one end of the second fastening button passes through the sleeve through the thread and abuts against the outer wall of the upright.

[0009] Preferably, a base is fixedly connected to the bottom of the upright, and a clamping assembly is provided at the bottom of the base.

[0010] Preferably, the clamping assembly includes a slide rod fixedly connected to one side of the bottom of the base, an adjustment knob rotatably connected to the top of the base, a screw fixedly connected to the bottom of the adjustment knob, one end of the screw passing through the base and rotatably connected thereto, a clamping plate threaded onto the screw, and the bottom of the slide rod movably passing through the clamping plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] Multiple crossbars are fixed to a single upright using support and deformation components, which can secure and guide the hoses. The folding rod perpendicular to the experimental platform can be stored in the crossbars, reducing space occupation. This iron frame can replace multiple traditional brackets with bases, integrating the brackets that guide the hoses into the inlet tank, waste tank, and permeate tank into the fixed bracket of the hollow fiber column. This eliminates the need for multiple base supports, reducing the area occupied by the experimental platform and facilitating cleaning of the platform after the experiment.

[0013] The hose retainer eliminates the need for constriction straps, preventing the hose from being flattened and deformed under external forces, thus affecting fluid flow. Multiple alternating hose retainers can be adjusted in angle and spacing to limit and secure the hose, preventing dragging; and each hose retainer can be adjusted independently, improving flexibility and adaptability.

[0014] Each support component can move independently, and its angle and height can be adjusted according to experimental needs, further improving the flexibility and adaptability of the iron stand; at the same time, the hollow fiber column can be quickly assembled and replaced through the spring clips, improving the ease of operation.

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a technical solution: such as Figures 1-6The hollow fiber special iron frame shown includes a vertical pole 1. A support assembly is provided on the outer wall of the vertical pole 1. The support assembly includes a C-shaped sleeve 2 slidably connected to the outer wall of the vertical pole 1. A crossbar 3 is fixedly connected to the outer wall of the C-shaped sleeve 2 with a notch. The end of the crossbar 3 near the C-shaped sleeve 2 and the notch of the C-shaped sleeve 2 together form a spacer groove 4. An internally threaded fastening sleeve 5 is threadedly connected to the outer wall of the crossbar 3 near the vertical pole 1. A sliding groove 6 is opened on the outer wall of the crossbar 3 along the length direction of the crossbar 3, and the sliding groove 6 completely penetrates the crossbar 3. An internally threaded sleeve 10 is threadedly connected to the outer wall of the crossbar 3 away from the vertical pole 1. The end of the threaded sleeve 10 away from the upright 1 is fixedly connected to a clamping sleeve 11, and the inner diameter of the clamping sleeve 11 is larger than the inner diameter of the threaded sleeve 10. The end of the crossbar 3 away from the upright 1 is provided with a deformation component for extension and bending. Rotate the threaded fastening sleeve 5 to bring the threaded fastening sleeve 5 closer to the upright 1, so that the elastically deformable C-shaped sleeve 2 is clamped on the upright 1 through the spacer groove 4 to form a fastening. Then, the folding rod 13 is pulled out from the crossbar 3. The folding rod 13 falls under the action of gravity. Then, rotate the clamping sleeve 11 to bring it closer to the abutment rod 22 and abut against the abutment rod 22, so that the folding rod 13 is fixed in a vertical state.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, the deformable assembly includes a fixed shaft 12 hinged in the slide groove 6, a stop rod 22 fixedly connected to the side surface of the fixed shaft 12, a folding rod 13 fixedly connected to one end of the stop rod 22, and a wire fastener for limiting the hose is provided on both the folding rod 13 and the crossbar 3.

[0026] like Figure 1 , Figure 2 and Figure 4 As shown, the cable fastener includes a movable sleeve 7 that is slidably connected to the crossbar 3 and the folding rod 13 respectively. A limit hook 9 is fixedly connected to the outer wall of the movable sleeve 7. A first fastening button 8 is threadedly connected to the side of the movable sleeve 7 away from the limit hook 9. A hose is connected to the feed port, return port and filtrate outlet of the hollow fiber column respectively. Each hose is limited and guided by the cable fastener on the crossbar 3 and the folding rod 13. The limit hooks 9 are alternately arranged on multiple movable sleeves 7. The movable sleeve 7 located in the middle is rotated at a certain angle so that the limit hook 9 presses the hose. Then the distance between the two movable sleeves 7 is shortened to fix the hose. Finally, the first fastening button 8 is rotated so that the end of the first fastening button 8 abuts against the crossbar 3 or the folding rod 13 to complete the fixation of the movable sleeve 7.

[0027] like Figure 1As shown, a sleeve 14 is slidably connected to the outer wall of the upright 1, and a spring piece 15 is fixedly connected to the outer wall of the sleeve 14. The spring piece 15 clamps the hollow fiber column through elastic deformation. A second fastening button 16 is threadedly connected to the side of the sleeve 14 away from the spring piece 15, and one end of the second fastening button 16 passes through the sleeve 14 through the thread and abuts against the outer wall of the upright 1. By rotating the second fastening button 16, the second fastening button 16 is released from the abutting state against the upright 1, so that the sleeve 14 slides along the height direction of the upright 1. After adjusting to a suitable position, the second fastening button 16 is reversed so that the second fastening button 16 abuts against the upright 1 again. Then the hollow fiber column is pressed between the two elastically deformable spring pieces 15. Then the spring pieces 15 bend to both sides under the action of force until the hollow fiber column is completely inserted between the two spring pieces 15. The two spring pieces 15 clamp and fix the hollow fiber column through the elastic deformation force.

[0028] like Figure 1 and Figure 4 As shown, a base 17 is fixedly connected to the bottom of the upright 1, and a clamping assembly is provided at the bottom of the base 17.

[0029] like Figure 1 and Figure 4 As shown, the clamping assembly includes a slide rod 20 fixedly connected to one side of the bottom of the base 17, an adjustment knob 18 rotatably connected to the top of the base 17, a screw 19 fixedly connected to the bottom of the adjustment knob 18, and one end of the screw 19 passes through the base 17 and is rotatably connected thereto. A clamping plate 21 is threadedly connected to the screw 19, and the bottom of the slide rod 20 moves through the clamping plate 21.

[0030] Working principle: When in use, place the iron stand on the edge of the experimental table, turn the adjustment knob 18 to drive the screw 19 to rotate, so that the clamping plate 21 moves towards the base 17, and the base 17 and the clamping plate 21 clamp and fix the edge of the experimental table.

[0031] Rotate the internal thread fastening sleeve 5 to bring it closer to the upright 1, so that the elastically deformable C-shaped sleeve 2 is clamped onto the upright 1 through the spacer groove 4 to form a fastening. Then, pull the folding rod 13 out from the crossbar 3. The folding rod 13 falls under the action of gravity. Then rotate the abutment sleeve 11 to bring it closer to the abutment rod 22 and abut against the abutment rod 22, so that the folding rod 13 is fixed in a vertical state.

[0032] By rotating the second fastening button 16, the second fastening button 16 is released from its abutment against the upright 1, allowing the clamp 14 to slide along the height direction of the upright 1. After adjusting to the appropriate position, the second fastening button 16 is reversed so that it abuts against the upright 1 again. Then, the hollow fiber column is pressed between the two elastically deformable spring pieces 15. The spring pieces 15 then bend to both sides under the force until the hollow fiber column is completely inserted between the two spring pieces 15. The two spring pieces 15 clamp and fix the hollow fiber column through the elastic deformation force.

[0033] Subsequently, hoses are connected to the inlet, reflux outlet, and filtrate outlet of the hollow fiber column, respectively. Each hose is limited and guided by the wire fasteners on the crossbar 3 and the folding rod 13. The limiting hooks 9 alternately set on multiple movable sleeves 7 rotate the movable sleeve 7 in the middle at a certain angle so that the limiting hook 9 presses down on the hose. Then the distance between the two movable sleeves 7 is shortened to fix the hose. Finally, the first fastening button 8 is rotated so that the end of the first fastening button 8 abuts against the crossbar 3 or the folding rod 13 to complete the fixation of the movable sleeve 7.
