Description

Technical Field

[0001] This utility model relates to the technical field of lithium battery electrolyte harmless treatment mechanism, specifically a lithium battery electrolyte harmless treatment mechanism based on supercritical CO2 coupled catalysis. Background Technology

[0002] In the process of harmless treatment of lithium battery electrolyte based on supercritical CO2 coupled catalysis, the gas filtration mechanism plays an indispensable role as a key component to ensure stable system operation and environmental safety.

[0003] This device is mainly used to filter the exhaust gas generated during the process, removing residual acidic gases, unreacted organic solvent vapors, and any fine particulate impurities that may be present, preventing these harmful substances from entering the atmosphere and avoiding corrosion and blockage of subsequent equipment.

[0004] However, existing gas filtration mechanisms typically place the filter screen longitudinally inside the gas delivery pipeline, and its filtration effect is highly dependent on the cross-sectional area of ​​the pipeline.

[0005] When processing large flow rates of gas, the limited cross-sectional area of ​​the pipeline and the excessively high gas velocity result in insufficient contact time between the gas and the filter screen, leading to a large amount of harmful substances not being adequately filtered and resulting in low filtration efficiency.

[0006] Meanwhile, in order to meet certain filtration requirements, the density and precision of the filter screen are often high. Under the impact of high-flow gas, the filter screen is easily clogged, which requires frequent replacement of the filter screen. This not only increases maintenance costs but also leads to extended equipment downtime, seriously affecting the overall efficiency of the harmless treatment of lithium battery electrolyte.

[0007] In view of the above, this application is hereby submitted. Utility Model Content

[0008] The purpose of this invention is to provide a harmless lithium battery electrolyte treatment mechanism based on supercritical CO2 coupled catalysis, so as to solve the problems mentioned in the background art.

[0009] To solve the above-mentioned technical problems, the present invention provides a harmless lithium battery electrolyte treatment mechanism based on supercritical CO2 coupled catalysis, comprising an exhaust pipe and a frame. The exhaust pipe is connected to one end of the frame, and a push plate is provided at the other end of the frame. A filter frame is fixedly connected to the push plate. The filter frame is V-shaped. A baffle adapted to the filter frame is provided in the frame. The connection between the exhaust pipe and the frame is located inside the filter frame.

[0010] Furthermore, a first groove is provided in the frame, and first sliders are provided at both ends of the filter frame. The filter frame is slidably connected in the first groove through the first sliders.

[0012] Furthermore, a positioning groove is provided at the top of the push plate, a mounting bracket is provided on the top surface of the frame, the bottom surface of the mounting bracket is flush with the top surface of the push plate, a storage groove is provided on the bottom surface of the mounting bracket, a sliding rod is slidably connected in the storage groove, a positioning block is provided at the lower end of the sliding rod, and the positioning block is adapted to the positioning groove and the storage groove.

[0013] Furthermore, a lifting block is provided on the top surface of the slide rod, and a spring is provided between the lifting block and the mounting bracket, with the spring sleeved around the outer wall of the slide rod.

[0016] Furthermore, a pull ring is provided on the push plate, and the pull ring is located on the side of the push plate away from the frame.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] In this invention, a V-shaped filter frame design is adopted, which greatly increases the contact area between the gas and the filter compared to the traditional flat filter.

[0024] 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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Please see Figure 1-4 This utility model provides a technical solution:

[0027] The lithium battery electrolyte harmless treatment mechanism based on supercritical CO2 coupled catalysis includes an exhaust pipe 1 and a frame 2. The exhaust pipe 1 is connected to one end of the frame 2, and a push plate 3 is provided at the other end of the frame 2. A filter frame 31 is fixedly connected to the push plate 3. The filter frame 31 is V-shaped. A first sliding groove 21 is provided in the frame 2. A first slider 32 is provided at both ends of the filter frame 31. The filter frame 31 is slidably connected to the first sliding groove 21 through the first slider 32. A baffle adapted to the filter frame 31 is provided in the frame 2. The connection between the exhaust pipe 1 and the frame 2 is located inside the filter frame 31.

[0028] The exhaust gas generated during the harmless treatment of lithium battery electrolyte based on supercritical CO2 coupled catalysis is introduced into the frame 2 through exhaust pipe 1.

[0029] Since the connection between the exhaust pipe 1 and the frame 2 is located inside the filter frame 31, the gas will directly impact the inner surface of the V-shaped filter frame 31 after entering the frame 2.

[0030] When the gas impacts the V-shaped filter frame 31, the flow rate decreases and the contact area with the filter increases. Harmful substances such as acidic gases, unreacted organic solvent vapors, and fine particulate impurities carried in the gas are intercepted and filtered as they pass through the filter.

[0031] As filtration continues, impurities gradually adhere to the filter screen of filter frame 31.

[0032] When a lot of impurities accumulate on the filter frame 31, affecting the filtration effect, the push plate 3 is pushed, and the push plate 3 drives the filter frame 31 to slide along the first slide groove 21.

[0033] Since the filter frame 31 is slidably connected to the first slide groove 21 via the first slider 32, the filter frame 31 can be completely extracted from the frame 2.

[0034] At this point, the filter screen on the filter frame 31 can be cleaned or replaced. After completion, the filter frame 31 can be slid back to its original position along the first slide groove 21 to continue the gas filtration work.

[0035] The V-shaped filter frame 31 design greatly increases the contact area between the gas and the filter compared to traditional flat filters.

[0036] When the gas flow rate is large, the gas can fully contact the filter screen, prolonging the contact time and allowing more harmful substances to be filtered out. This effectively overcomes the problem of poor filtration effect caused by the limitation of pipe cross-sectional area and significantly improves the overall filtration efficiency.

[0037] The increased contact area reduces the load per unit area of ​​the filter screen, preventing impurities from accumulating too concentratedly in one place, thus slowing down the clogging of the filter screen. This reduces the frequency of filter screen replacement, lowers maintenance costs, and also reduces downtime due to maintenance, improving the continuity and overall efficiency of the harmless treatment of lithium battery electrolyte.

[0038] The filter frame 31 is slidably connected to the first slide groove 21 via the first slider 32. Combined with the design of the push plate 3, this makes the disassembly and installation of the filter frame 31 very convenient.

[0039] Staff can easily pull out the filter frame 31 for cleaning or filter replacement simply by pushing the push plate 3, without the need for complicated disassembly tools and cumbersome operating procedures, thus improving the convenience and efficiency of maintenance work.

[0040] The length of the filter frame 31 can be customized by adjusting the length of the frame 2 according to the actual amount of gas to be processed.

[0041] When dealing with large volumes of gas, the frame 2 and filter frame 31 can be extended to further increase the filtration area and meet higher filtration requirements, demonstrating strong flexibility and adaptability.

[0042] The frame 2 has a second slide groove 22. The lower end of the push plate 3 is connected to a dustproof net 33. The two ends of the dustproof net 33 are provided with second sliders 34 that are adapted to the second slide groove 22. The dustproof net 33 is slidably connected to the second slide groove 22 through the second sliders 34.

[0043] The dustproof net 33 is slidably connected to the second slide groove 22 of the frame 2 via the second slider 34, forming an additional protective barrier.

[0044] When the mechanism is not in operation, the dustproof net 33 can be slid to cover the opening of the entire frame 2, effectively blocking external dust and debris from entering the interior of the frame 2, preventing these impurities from contacting the filter frame 31, preventing the filter from being blocked by external impurities in advance, extending the service life of the filter, and ensuring that the filter frame 31 is always in good operating condition when working.

[0045] During the process of removing the filter frame 31 for cleaning or replacement, the dustproof net 33 can prevent impurities remaining inside the frame 2 from falling or flying outside the mechanism and polluting the working environment.

[0046] At the same time, it also prevents these impurities from accumulating randomly in the frame 2, affecting the normal sliding of components such as the push plate 3 and the filter frame 31, ensuring the smooth operation of each component of the mechanism, and reducing the probability of mechanical failures caused by impurities.

[0047] The top of the push plate 3 is provided with a positioning groove 35, the top surface of the frame 2 is provided with a mounting bracket 4, the bottom surface of the mounting bracket 4 is flush with the top surface of the push plate 3, the bottom surface of the mounting bracket 4 is provided with a storage groove 41, a sliding rod 42 is slidably connected in the storage groove 41, and a positioning block 43 is provided at the lower end of the sliding rod 42. The positioning block 43 is adapted to the positioning groove 35 and the storage groove 41.

[0048] A lifting block 44 is provided on the top surface of the slide rod 42, and a spring 45 is provided between the lifting block 44 and the mounting bracket 4. The spring 45 is sleeved around the outer wall of the slide rod 42.

[0049] The positioning block 43 has a chamfer 46, which is located at the end of the push plate 3 on the positioning block 43.

[0050] When the push plate 3 slides to the working position or the storage position, the positioning block 43 can accurately fall into the positioning groove 35 at the top of the push plate 3 under the elastic force of the spring 45, forming a reliable positioning structure.

[0051] This effectively prevents the push plate 3 from shifting during gas impact or equipment vibration, ensuring that the filter frame 31 and dustproof net 33 are always in the correct working position and maintain a stable filtration effect.

[0052] Meanwhile, the cooperation between the positioning block 43 and the positioning groove 35 provides additional support for the push plate 3, enhancing the structural stability of the entire mechanism during operation.

[0053] By lifting the lifting block 44, the staff can overcome the elastic force of the spring 45 and pull the positioning block 43 out of the positioning groove 35. Then, the push plate 3 can slide freely to clean or replace the filter frame 31 or adjust the position of the dustproof net 33.

[0054] After the operation is completed, release the lifting block 44, and the positioning block 43 will automatically reset under the action of the spring 45, thus repositioning.

[0055] The entire process requires no complex tools, is simple and quick to operate, and significantly improves the efficiency of equipment maintenance and operation.

[0056] The elastic force provided by the spring 45 ensures that the positioning block 43 and the positioning groove 35 fit tightly together, effectively preventing the push plate 3 from sliding due to accidental collision or accidental contact.

[0057] Especially during equipment operation, it can prevent the pusher plate 3 from moving unexpectedly, which could lead to filter failure or damage to the internal structure, thus ensuring the safety and reliability of equipment operation.

[0058] The chamfer 46 on the positioning block 43 serves as a guide during the sliding of the push plate 3, allowing the positioning block 43 to slide into the positioning groove 35 more smoothly, reducing the difficulty of installation and operation, and improving the assembly efficiency and user experience of the equipment.

[0059] Rubber pads are provided at both the end of the push plate 3 near the frame 2 and the end of the baffle near the push plate 3.

[0060] A pull ring is provided on the push plate 3, and the pull ring is located on the side of the push plate 3 away from the frame 2.

[0061] The rubber pads installed near the end of the push plate 3 and the end of the baffle near the push plate 3 can fit tightly against the inner wall of the frame 2 and the surface of the baffle when the push plate 3 slides to the working position, forming a good sealing structure.

[0062] This effectively prevents exhaust gases containing harmful substances such as acidic gases and organic solvent vapors from leaking from the connection between the push plate 3 and the frame 2 and the baffle during the gas filtration process, avoiding pollution to the working environment and protecting the health and safety of the operators.

[0063] The pull ring on the side of the push plate 3 away from the frame 2 provides a convenient and stable point of force application for the staff.

[0064] When it is necessary to slide the push plate 3 to clean or replace the filter frame 31 or adjust the position of the dust screen 33, the staff can easily pull the push plate 3 through the pull ring. Compared with directly pushing and pulling the edge of the push plate 3, using the pull ring is more labor-saving and can better control the sliding direction and speed of the push plate 3, effectively improving the convenience and efficiency of equipment operation and making maintenance work easier and more convenient.
