[0002] Polyimide film is usually made of pyromellitic dianhydride and diamine-based diphenyl ether in a strong polar solvent through polycondensation and casting film, and then imidized. As a kind of high-performance material, polyimide film has a wide range of applications in aerospace, electronics, biomedicine and other fields due to its excellent heat resistance, mechanical properties, electrical properties and chemical stability. However, a large amount of waste gas will inevitably be generated during its production process, and these waste gases not only contain volatile organic compounds, but also contain a large amount of particulate matter.
[0003] In the prior art, these waste gases are usually treated by a waste gas recovery device. The waste gas recovery device tries to capture the particles in the waste gas through the built-in filter screen or other filter medium. However, due to the high content of particles in the waste gas generated during the production process of polyimide film, these particulate matters are easy to accumulate on the surface of the filter screen, causing the filter screen to be blocked, so the filter screen needs to be replaced.
[0004] Since the filter screen is usually designed to closely fit the waste gas recovery device to ensure the filtering effect, a large number of components need to be disassembled when replacing the filter screen, which not only consumes a lot of time and effort, but also may cause damage to the equipment due to improper operation.

DETAILED DESCRIPTION
[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0025] As Figures 1 to 5 shown, a kind of polyimide film waste gas recovery equipment, including waste gas treatment box 1, waste gas filtering cavity 2 is opened in waste gas treatment box 1, the top of waste gas treatment box 1 is equipped with exhaust port 3 with waste gas filtering cavity 2 being communicated, the side of waste gas treatment box 1 is equipped with first slot 4 and air inlet 5 with waste gas filtering cavity 2 being communicated, filter frame 6 is slidably arranged in first slot 4, waste gas enters waste gas filtering cavity 2 in waste gas treatment box 1 by air inlet 5.In waste gas filtering cavity 2, waste gas is filtered by filter frame 6, and removes impurities and harmful substances therein.
[0026] The side of first slot 4 is equipped with first chute 7, limit lock block 8 is slidably arranged in first chute 7, first spring 9 is installed in first chute 7, one end of first spring 9 is connected with first chute 7, the other end of first spring 9 is connected with limit lock block 8, the top of first slot 4 is equipped with second chute 10, sealing sliding plate 11 is slidably arranged in second chute 10.
[0027] When the filter frame 6 needs to be installed, it is inserted from the side first slot 4 of the exhaust gas treatment box 1. During the insertion process, the limiting lock block 8 is slid out of the first sliding groove 7 under the support of the first spring 9, and abuts against one side of the filter frame 6, realizing the locking of the filter frame 6 in the first slot 4. At the same time, the sealing sliding plate 11 slides in the second sliding groove 10, and the bottom abuts against the top of the filter frame 6, ensuring the sealing between the filter frame 6 and the exhaust gas treatment box 1, while not affecting the sliding of the filter frame 6 in the first slot 4.
[0028] When the filter frame 6 needs to be replaced, first slide the limiting lock block 8 to compress the first spring 9, so that the limiting lock block 8 slides into the first sliding groove 7, thereby canceling the locking of the filter frame 6 in the first slot 4. Then, the filter frame 6 is pulled out of the first slot 4. At this time, the sealing sliding plate 11 slides out of the second sliding groove 10 to seal the first slot 4, preventing exhaust gas leakage.
[0029] By sliding the limiting lock block 8 and the first spring 9, automatic locking of the filter frame 6 is realized, and unlocking of the filter frame 6 can be completed by only sliding the limiting lock block 8, simplifying the process of replacing the filter frame 6, avoiding the tedious operation of disassembling a large number of components, saving time and effort, and also reducing the wear and damage of equipment components, thereby prolonging the service life of the equipment and reducing the maintenance cost.
[0030] When the filter frame 6 is pulled out of the first slot 4 of the exhaust gas treatment box 1, the sealing sliding plate 11 can slide out of the second sliding groove 10 to fill the space originally occupied by the filter frame 6, realizing instant sealing of the first slot 4. This function effectively prevents exhaust gas leakage during the replacement of the filter frame 6, ensuring the continuity and stability of the exhaust gas treatment system.
[0031] Reference Figure 4 As shown, in some embodiments, a second spring 12 is installed in the second sliding groove 10, one end of the second spring 12 is connected with the second sliding groove 10, and the other end of the second spring 12 is connected with the sealing sliding plate 11.
[0032] When the filter frame 6 is inserted into the first slot 4 and locked, the second spring 12 is in a compressed state at this time, and the sealing sliding plate 11 is elastically supported in the second sliding groove 10 by the second spring 12, ensuring that the bottom is tightly fitted with the top of the filter frame 6, realizing good sealing effect.
[0033] When the filter frame 6 needs to be replaced, the sealing sliding plate 11 will automatically slide out of the second sliding groove 10 under the action of the second spring 12 as the filter frame 6 is pulled out, filling the space left by the filter frame 6, realizing instant sealing effect. At the same time, when the new filter frame 6 is inserted, the sealing sliding plate 11 will also be tightly fitted with the top of the new filter frame 6 under the push of the second spring 12.
[0034] Reference Figure 4 As shown, in some embodiments, the side of the sealing sliding plate 11 is fixedly provided with a first handle 13. The side of the exhaust gas treatment box 1 is provided with an avoidance slot 14 communicating with the second sliding slot 10, and the first handle 13 is in sliding fit connection with the avoidance slot 14. The arrangement of the first handle 13 enables the user to hold and move the sealing sliding plate 11 more conveniently without the need for additional tools or force, greatly improving the convenience of operation.
[0035] Reference Figure 1 As shown, in some embodiments, the side of the exhaust gas treatment box 1 is provided with a second insertion slot 15 communicating with the exhaust gas filtering cavity 2, and the second insertion slot 15 is located at the bottom of the exhaust gas filtering cavity 2. A slag collecting frame 16 is fitted in the second insertion slot 15. During the exhaust gas filtering process, the generated residues will fall into the slag collecting frame 16. When the residues in the slag collecting frame 16 accumulate to a certain extent, the user can conveniently take them out of the second insertion slot 15 for cleaning and disposal.
[0036] By arranging the second insertion slot 15 and the slag collecting frame 16, the user can more conveniently collect and clean the residues generated during the exhaust gas filtering process, thereby improving the maintenance efficiency of the equipment. Timely cleaning of the residues helps to avoid the situation of blockage or damage to the equipment components caused by their accumulation in the exhaust gas filtering cavity 2. Therefore, this helps to reduce the failure rate of the equipment and prolong the service life of the equipment.
[0037] Reference Figure 1 As shown, in some embodiments, a rain cover 17 is fixedly arranged at the port of the exhaust port 3. The rain cover 17 can effectively block rainwater from entering the exhaust port 3, avoiding equipment failure or performance degradation caused by rainwater. By preventing rainwater erosion, the rain cover 17 helps to prolong the service life of the exhaust gas recovery equipment and reduce maintenance and replacement costs.
