Technical Field
[0001] This utility model relates to the field of lithium-ion screening membrane module technology, specifically a recyclable lithium-ion screening membrane module. Background Technology
[0002] A lithium-ion sieving membrane module is a device for sieving and separating lithium ions. It is used to accurately separate lithium ions from anions / solvents. It achieves efficient sieving through confined channels constructed from two-dimensional materials (such as metal-organic nanosheets) while maintaining a high ion throughput.
[0003] The existing technical solution has the following drawbacks: when fixing the lithium-ion screening membrane in the lithium-ion screening membrane assembly, the lithium-ion screening membrane is bonded and fixed with tape. Since the lithium-ion screening membrane is bonded and fixed with tape, the fixing effect of the lithium-ion screening membrane is limited. Therefore, we propose a recyclable lithium-ion screening membrane assembly to solve the problems mentioned above. Utility Model Content
[0004] The purpose of this invention is to provide a recyclable lithium-ion screening membrane assembly to solve the problem that, in the lithium-ion screening membrane assembly mentioned in the background art, the lithium-ion screening membrane is fixed by adhesive tape, which results in a limited fixing effect on the lithium-ion screening membrane.
[0005] To achieve the above objectives, the present invention provides the following technical solution: As a preferred technical solution of the present invention, a recyclable lithium-ion screening membrane assembly includes a connecting mounting plate, a lithium-ion screening membrane body is disposed in the middle of the plate, and a thin film electrode is disposed on the upper front side of the lithium-ion screening membrane body. Also includes: A movable rod is installed on the outside of the connecting mounting plate, and a movable structure is provided on the inside of the connecting mounting plate. The movable structure includes a connecting spring, a connecting rod, and a limiting plate. The connecting spring is located on the inside of the connecting mounting plate, and a limiting plate is fixedly installed on the inside of the connecting spring. A connecting rod is installed on the outside of the middle part of the limiting plate. A fixing block is installed on the outer side of the middle of the connecting mounting plate, and a limiting rod is connected to the middle of the fixing block. A disassembly structure is connected to the outer side of the lower end of the limiting rod. The disassembly structure includes a moving block, a clamping plate, and an anti-slip plate. The moving block is installed on the outer side of the lower end of the limiting rod, and a clamping plate is connected to the inner side of the moving block. An anti-slip plate is installed on the inner side of the clamping plate.
[0006] Preferably, a connecting block is further provided on the inner side of the connecting mounting plate, and a blocking plate is fixedly installed on the inner side of the connecting block, and an adhesive block is provided on the inner side of the blocking plate.
[0007] Preferably, the connecting block is connected to the connecting mounting plate via epoxy resin AB glue.
[0008] Preferably, the movable block and the connecting mounting plate are slidably connected, and the movable blocks are symmetrically distributed about the center line of the connecting mounting plate.
[0009] Preferably, the movable block and the limiting rod are connected by a thread and the threaded connection serves to limit the installation of the anti-slip plate.
[0010] Preferably, the movable rod and the connecting mounting plate are connected by a thread, and the movable rod and the limiting plate are connected by a fitted connection.
[0011] Preferably, the mounting anti-slip plate and the lithium ion screening membrane body are bonded together, and the lithium ion screening membrane body and the connecting mounting plate are snap-fitted together.
[0012] Preferably, the limiting plate and the connecting mounting plate are telescopically sliding connected, and the lower inner side of the limiting plate is inclined.
[0013] Compared with the prior art, the present invention has at least the following beneficial effects: the recyclable lithium-ion screening membrane assembly is provided with a movable structure that can move the clamping plate to install the screening membrane, and is also provided with a disassembly structure that can disassemble the screening membrane to recycle it. 1. The connecting block is fixedly installed inside the connecting mounting plate using epoxy resin AB glue. After applying adhesive to the inside of the baffle plate, the lithium ion screening membrane body is placed inside the connecting mounting plate, so that the lithium ion screening membrane body is snapped together inside the connecting mounting plate. This makes it easier to install the lithium ion screening membrane body by connecting it inside the adhesive block. 2. The lithium-ion screening membrane body pushes the limiting plate to slide outward, causing the limiting plate to drive the connecting rod to slide outward inside the connecting mounting plate. This causes the limiting plate to compress the connecting spring, which in turn causes the connecting spring to drive the limiting plate to slide inward to clamp the lithium-ion screening membrane body. Then, the moving rod is manually rotated to make the moving rod threaded on the outside of the connecting mounting plate, so that the moving rod fits and connects to the outside of the limiting plate. This allows the moving rod to limit the limiting plate, facilitating further installation and limiting of the lithium-ion screening membrane body. 3. By rotating the limiting rod, the limiting rod is threaded into the middle of the fixed block, causing the limiting rod to move upward. This causes the limiting rod to separate from the upper outer side of the moving block. Pulling the moving block outward causes it to slide the clamping plate outward, which in turn causes the clamping plate to slide the anti-slip plate outward. This separates the anti-slip plate from the outer side of the lithium ion screening membrane body. Pulling the lithium ion screening membrane body inward then separates it from the inner side of the adhesive block, thus separating the lithium ion screening membrane body from the inside of the connecting mounting plate. This facilitates the disassembly of the lithium ion screening membrane body, allowing it to be recycled after plasma cleaning. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0017] Please see Figures 1-7 The present invention provides the following technical solution: A recyclable lithium-ion screening membrane assembly includes: a connecting mounting plate 1, a blocking plate 2, a lithium-ion screening membrane body 3, a connecting block 4, an adhesive block 5, a moving block 6, a thin film electrode 7, a moving rod 8, a fixing block 9, a limiting rod 10, a clamping plate 11, a mounting anti-slip plate 12, a connecting spring 13, a connecting rod 14, and a limiting plate 15. When using it for work, specifically such as Figure 1 and Figure 2 As shown, a connecting block 4 is movably connected to the inner side of the connecting mounting plate 1. A baffle plate 2 is fixedly installed inside the connecting block 4. An adhesive block 5 is provided inside the baffle plate 2. A lithium-ion screening membrane body 3 is installed inside the adhesive block 5. Epoxy resin AB glue is manually applied to the outer side of the connecting block 4. Then, the baffle plate 2 is manually placed inside the connecting mounting plate 1, so that the baffle plate 2 drives the connecting block 4 to engage inside the connecting mounting plate 1. Thus, the epoxy resin AB glue fixes the connecting block 4 inside the connecting mounting plate 1. After applying the adhesive block 5 to the inner side of the baffle plate 2, the lithium-ion screening membrane body 3 is placed inside the connecting mounting plate 1, so that the lithium-ion screening membrane body 3 engages inside the connecting mounting plate 1. Thus, the lithium-ion screening membrane body 3 is connected inside the adhesive block 5, which facilitates the installation of the lithium-ion screening membrane body 3. Specific examples Figure 3 , Figure 5 , Figure 6 and Figure 7As shown, a connecting spring 13 is provided on the inner side of the connecting mounting plate 1, a limiting plate 15 is fixedly installed on the inner side of the connecting spring 13, a connecting rod 14 is fixedly installed on the outer side of the middle part of the limiting plate 15, and a moving rod 8 is movably connected to the outer side of the connecting mounting plate 1. The lithium ion screening membrane body 3 pushes the limiting plate 15 to slide outward, so that the limiting plate 15 drives the connecting rod 14 to slide outward inside the connecting mounting plate 1 under the outward sliding action of the limiting plate 15. This causes the limiting plate 15 to drive the connecting spring 13 to compress, and then the connecting spring 13 drives the limiting plate under the elastic action of the connecting spring 13. 15 slides inward to clamp the lithium ion screening membrane body 3, and then manually twists the moving rod 8, so that the moving rod 8 is threaded on the outside of the connecting mounting plate 1 under the twisting action. Thus, under the action of the thread between the moving rod 8 and the connecting mounting plate 1, the moving rod 8 moves inward, and then the moving rod 8 fits and connects to the outside of the limiting plate 15, so that the moving rod 8 limits the limiting plate 15, which facilitates further installation and limiting of the lithium ion screening membrane body 3. Then, the thin film electrode 7 fixedly installed on the upper front end of the lithium ion screening membrane body 3 can improve the diffusion rate of lithium ions. Specific examples Figure 1 , Figure 3 and Figure 4 As shown, a fixing block 9 is fixedly installed on the outer side of the middle of the connecting mounting plate 1. A limiting rod 10 is movably connected to the middle of the fixing block 9. A movable block 6 is movably installed on the outer side of the lower end of the limiting rod 10. A clamping plate 11 is fixedly installed on the inner side of the movable block 6. An anti-slip plate 12 is fixedly installed on the inner side of the clamping plate 11. By manually turning the limiting rod 10, the limiting rod 10 is threadedly connected to the middle of the fixing block 9. Under the thread action between the limiting rod 10 and the fixing block 9, the limiting rod 10 moves upward, thereby separating the limiting rod 10 from the outer side of the upper end of the movable block 6. Then, by manually pulling the movable block 6 outward, the movable block 6 is connected to the fixing block 9 under the action of the tension. The outer side of the mounting plate 1 slides outward, thereby causing the moving block 6 to slide outward along with the clamping plate 11 under the sliding action between the moving block 6 and the connecting mounting plate 1. This causes the clamping plate 11 to slide outward along with the mounting anti-slip plate 12, separating the mounting anti-slip plate 12 from the outer side of the lithium ion screening membrane body 3. Then, the lithium ion screening membrane body 3 is manually pulled inward, separating it from the inner side of the adhesive block 5. This allows the lithium ion screening membrane body 3 to separate from the inside of the connecting mounting plate 1, facilitating the disassembly of the lithium ion screening membrane body 3 and enabling it to be recycled after plasma cleaning.
