Description
Technical Field
[0001] This utility model relates to the field of ultra-high pressure membrane sealing technology, and specifically to an ultra-high pressure membrane sealing device. Background Technology
[0002] Ultra-high pressure membrane sealing refers to a technical solution that achieves leak-proof fluid control and simultaneous material separation under ultra-high pressure conditions by utilizing the inherent characteristics of the membrane module or its matching sealing structure. The core technology combines sealing assurance with membrane separation under high pressure. Ultra-high pressure membrane sealing devices are widely used in petrochemical, hydrogen refueling stations, and ultra-high pressure vessels to achieve sealing functions under ultra-high pressure environments.
[0003] Membranes are typically fixed in dedicated membrane housings or support structures, with sealing structures (such as elastic sealing rings or metal gaskets) designed at their edges and interfaces, or filling gaps through the rigid / elastic deformation of the membrane itself (such as some high-pressure diaphragms). After production, membranes need to be transported. Current mainstream ultra-high-pressure membrane sealing devices suffer from a limited structural design; these devices can only perform basic sealing operations and are difficult to adapt to the transport operations after membrane element production, thus limiting their practicality.
[0004] Therefore, we propose an ultra-high pressure membrane sealing device. Utility Model Content
[0005] The main purpose of this utility model is to provide an ultra-high pressure membrane sealing device. A sealing ring is connected to the outside of the ultra-high pressure membrane body, and the sealing ring is then matched with a flange to form a multi-layer sealing and protection structure. This can effectively prevent external dust, water vapor and other impurities from entering the interior of the ultra-high pressure membrane body. At the same time, during subsequent transportation, the stable sealing structure can prevent the ultra-high pressure membrane body from failing due to external environmental interference, ensuring that the ultra-high pressure membrane is always in a good working ready state, which can effectively solve the problems in the background art.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] An ultra-high pressure membrane sealing device includes a flange, a sealing ring, an ultra-high pressure membrane body, positioning components, and a transport box for placing the ultra-high pressure membrane body. The sealing ring is connected to the outside of the ultra-high pressure membrane body, and the flange is connected to the outside of the sealing ring. Two sets of opposing positioning components are fixedly connected to both ends of the flange by self-tapping screws. The positioning components include a support plate, an arc-shaped part, a plug, a positioning part, a clamping part, and a first bolt.
[0008] The operating box has a placement cavity, and grooves are provided at the center of both sides of the placement cavity. Support platforms for supporting positioning components are provided at the lower part of the inner walls at both ends of the placement cavity. The top of the operating box has a sealing groove that matches the top cover. The top cover is horizontally fastened to the top of the operating box. The upper surface of the top cover has operating grooves at both ends for installing knobs. A box body is fixedly inserted into the lower surface of the top cover below the operating grooves. The bottom of the box body is connected to a pressure plate for defining the position of the positioning component through a top rod.
[0009] By adopting the above technical solution, a sealing ring is connected to the outside of the ultra-high pressure membrane body, and the sealing ring is then matched with a flange to form a multi-layer sealing and protection structure. This can effectively prevent external dust, water vapor and other impurities from entering the interior of the ultra-high pressure membrane body. At the same time, during subsequent transportation, the stable sealing structure can prevent the ultra-high pressure membrane body from failing due to external environmental interference, ensuring that the ultra-high pressure membrane is always in a good working ready state.
[0010] Specifically, the two ends of the arc-shaped component are fixedly connected to the flange by self-tapping screws, and a support plate is fixedly connected to the center of the side of the arc-shaped component away from the flange. The two ends of the support plate away from the arc-shaped component are provided with slots for installing plugs.
[0011] Specifically, one end of the plug passes through the support plate and is vertically inserted into one end of the positioning component. Multiple sets of the plug are arranged relatively parallel to each other. The upper surface of the support plate is threaded with a first bolt at the location of the plug.
[0012] Specifically, a locking device is fixedly inserted at the center of the lower end face of the positioning component, and a slot adapted to the locking device is provided at the top of the support platform.
[0013] Specifically, a threaded rod is vertically installed inside the box. The top end of the threaded rod passes through the push plate, the box, and the top cover in sequence and is fixedly connected to the bottom end of the knob. Both sides of the push plate are slidably connected to the inner wall of the box.
[0014] Specifically, multiple relatively parallel push rods are vertically inserted into the lower end face of the push plate. The bottom end of the push rod passes through the box body and is vertically inserted into the upper end face of the pressure plate. A rubber pad is fixedly glued to the lower end face of the pressure plate and contacts the top of the positioning component.
[0015] The beneficial effects of this utility model are as follows: The ultra-high pressure membrane sealing device of this utility model has a sealing ring connected to the outside of the ultra-high pressure membrane body, and the sealing ring is then matched with a flange to form a multi-layer sealing and protective structure. This effectively prevents external dust, moisture, and other impurities from entering the interior of the ultra-high pressure membrane body. Furthermore, during subsequent transportation, the stable sealing structure prevents the ultra-high pressure membrane body from failing due to external environmental interference, ensuring that the ultra-high pressure membrane is always in a good working ready state. Through the tight fit between the arc-shaped component and the flange and the fixing with self-tapping screws, the precise docking of the positioning component and the flange can be quickly achieved. The extension length of the positioning component can be flexibly adjusted according to the overall height of the ultra-high pressure membrane body; simply pulling the positioning component... Insert the clip into the corresponding slot, and then lock the plug in place with the first bolt to complete the positioning and fixing device. Through multiple fixing measures, the device effectively prevents the components from shifting or shaking, ensuring the safe transport of the ultra-high pressure membrane and its components. The locking of the plug in place with the first bolt prevents the positioning component from shifting laterally during transport, ensuring the stability of the positioning structure. After the top cover is fastened, rotating the knob drives the threaded rod to rotate, causing the push plate and top rod to push the pressure plate down. The elastic compression of the rubber pad at the lower end of the pressure plate achieves the longitudinal fixing of the positioning component, preventing the components from shaking up and down. Through the dual fixing of lateral and longitudinal directions, a comprehensive and stable protection is formed, effectively reducing the risk of component damage and ultra-high pressure membrane displacement caused by transport shaking.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0022] As one embodiment of this utility model, such as Figures 1-3 As shown, the ultra-high pressure membrane sealing device of this utility model includes a flange 8, a sealing ring 9, an ultra-high pressure membrane body 10, a positioning component 5, and a transport box 1 for placing the ultra-high pressure membrane body 10. The sealing ring 9 is connected to the outside of the ultra-high pressure membrane body 10, and the flange 8 is connected to the outside of the sealing ring 9. Two sets of opposing positioning components 5 are fixedly connected to both ends of the flange 8 by self-tapping screws. The positioning component 5 includes a support plate 6, an arc-shaped part 7, a plug 12, a positioning part 13, a clip 14, and a first bolt 15.
[0023] The operating box 1 is provided with a placement cavity 2. The placement cavity 2 has a groove 3 at the center of both sides. The lower part of the inner wall at both ends of the placement cavity 2 is provided with a support platform 4 for supporting the positioning component 5. The top of the operating box 1 is provided with a sealing groove 16 that matches the top cover 17. The top cover 17 is horizontally fastened to the top of the operating box 1. The upper surface of the top cover 17 is provided with an operation groove 21 at both ends for installing the knob 22. The lower surface of the top cover 17 is fixedly inserted into the box body 18 below the operation groove 21. The bottom end of the box body 18 is connected to a pressure plate 19 for limiting the position of the positioning component 13 through a top rod 25.
[0024] In use, the inner arc surface of the arc-shaped part 7 is aligned with the outer circumference of the flange 8, and the two ends of the arc-shaped part 7 are fixed to the flange 8 using self-tapping screws to ensure that the two sets of positioning components 5 are symmetrically distributed on both sides of the flange 8. Then, the end of the support plate 6 away from the arc-shaped part 7 is aligned with the top of the positioning part 13. According to the overall height of the ultra-high pressure membrane body 10, the extension length of the positioning part 13 is adjusted, and the positioning part 13 is pulled away from the flange 8 until the bottom end of the clip 14 at the bottom of the positioning part 13 can be inserted into the slot 20 at the top of the support platform 4. Then, the first bolt 15 is screwed into the threaded hole on the upper end of the support plate 6 until the bottom end of the bolt presses against the surface of the plug-in 12 to lock and fix the plug-in 12, preventing the positioning part 13 from moving during transportation.
[0025] The present invention also includes that the two ends of the arc-shaped component 7 are fixedly connected to the flange 8 by self-tapping screws, and a support plate 6 is fixedly connected at the center of the side of the arc-shaped component 7 away from the flange 8. The two ends of the support plate 6 away from the arc-shaped component 7 are provided with slots 11 for installing the plug-in 12.
[0026] The present invention also includes that one end of the plug-in 12 passes through the support plate 6 and is vertically inserted into one end of the positioning member 13, and multiple sets of plug-in 12 are arranged in parallel relative to each other, and the upper end face of the support plate 6 is threadedly connected to the position of the plug-in 12 with a first bolt 15.
[0027] The present invention also includes a locking member 14 fixedly inserted at the center of the lower end face of the positioning member 13, and a slot 20 adapted to the locking member 14 is provided at the top of the support platform 4.
[0028] The present invention also includes a threaded rod 23 vertically installed inside the box body 18. The top end of the threaded rod 23 passes through the push plate 24, the box body 18, and the top cover 17 in sequence and is fixedly connected to the bottom end of the knob 22. Both sides of the push plate 24 are slidably connected to the inner wall of the box body 18.
[0029] This utility model also includes a plurality of relatively parallel push rods 25 vertically inserted into the lower end face of the push plate 24, the bottom end of the push rods 25 passing through the box body 18 and vertically inserted into the upper end face of the pressure plate 19, and the lower end face of the pressure plate 19 is fixedly glued with a rubber pad and in contact with the top end of the positioning member 13.
[0030] In use, the ultra-high pressure diaphragm body 10, with the sealing ring 9 fitted, is assembled into the central through hole of the flange 8. Then, two sets of positioning components 5 are taken. Each set of positioning components 5 includes a support plate 6, an arc-shaped component 7, a plug 12, a positioning component 13, a clip 14, and a first bolt 15. The inner arc surface of the arc-shaped component 7 is fitted against the outer circumference of the flange 8, and self-tapping screws are used to fix both ends of the arc-shaped component 7 to the flange 8, ensuring that the two sets of positioning components 5 are symmetrically distributed on both sides of the flange 8. Then, the support plate 6 is moved away from the flange 8. One end of the arc-shaped part 7 is aligned with the top of the positioning part 13. The extension length of the positioning part 13 is adjusted according to the overall height of the ultra-high pressure membrane body 10. The positioning part 13 is pulled away from the flange 8 until the bottom end of the clip 14 at the bottom of the positioning part 13 can be inserted into the slot 20 at the top of the support platform 4. Then the first bolt 15 is screwed into the threaded hole on the upper surface of the support plate 6 until the bottom end of the bolt presses against the surface of the plug-in 12, thereby locking and fixing the plug-in 12 to prevent the positioning part 13 from moving during transportation.
[0031] Then, the top cover 17 is horizontally fastened to the top of the operating box 1. The top cover 17 is fixedly connected to both ends of the top of the operating box 1 by the second bolt. Then, the knob 22 in the operating groove 21 at both ends of the top cover 17 is rotated, which drives the threaded rod 23 inside the box 18 to rotate. Since the push plate 24 is slidably connected to the inner wall of the box 18 on both sides, the threaded rod 23 will push the push plate 24 to move vertically downward when it rotates. During the downward movement of the push plate 24, the top rod 25 at its lower end will drive the pressure plate 19 to move downward synchronously until the rubber pad at the lower end of the pressure plate 19 is tightly attached to the top of the positioning part 13. At this time, the knob 22 is stopped, and the positioning part 13 is longitudinally fixed by the elastic compression of the rubber pad to prevent the component from shaking up and down during transportation.
