[0002] PI is mainly polymerized from dianhydride and diamine as raw materials. At present, there are mainly four methods: one-step method, two-step method, three-step method and gas-phase precipitation method. Among them, the two-step method is the most commonly used industrial method for synthesizing PI in the manufacture of PI films. PI films have good high and low temperature resistance, environmental stability, mechanical properties and excellent dielectric properties, and are widely used in many basic industries and high-tech fields.

[0003] In the production process of PI products, it is usually necessary to use an impurity adsorption and purification device to adsorb and filter impurities in the raw material solution to ensure the quality of subsequent PI products. However, when the impurity adsorption and purification device is in use, it is necessary to periodically clean the filter element and filter screen. The disassembly of the filter element and filter screen of most impurity adsorption and purification devices is too cumbersome, which is a bit inconvenient. Therefore, a deep impurity adsorption and purification device is proposed to solve the above problems. Summary of the Utility Model

Specific implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 to 2 , a deep impurity adsorption and purification device in this embodiment includes a base 1. A purification box 2 is fixed on the top of the base 1. An observation window 13 is inlaid on the back of the purification box 2. The provided observation window 13 facilitates observing the adsorption situation inside the purification box 2. A cover plate 3 is fixed on the top of the purification box 2. The provided cover plate 3 is used to close the purification box 2. A handle 14 is fixed on the top of the cover plate 3. A sponge pad is sleeved on the outer surface of the handle 14. The provided handle 14 makes it convenient to pull the cover plate 3 upward. A sealing ring is fixed on the bottom of the cover plate 3. A sealing groove adapted to the sealing ring is opened on the top of the purification box 2. The provided sealing ring and sealing groove can further improve the sealing performance between the purification box 2 and the cover plate 3. Fixing components 4 are arranged on both the left and right sides of the purification box 2. Fixing blocks 5 inserted with the fixing components 4 are fixed on both the left and right sides of the cover plate 3. The fixing components 4 are used to fix the cover plate 3 and the purification box 2.

[0023] In addition, a limiting block 6 is fixed inside the purification box 2. The provided limiting block 6 is used to prevent the adsorption assembly 7 from moving downward. The adsorption assembly 7 is placed on the top of the limiting block 6. The adsorption assembly 7 includes a mounting frame 701, a filter screen 702, and a filter element 703. The mounting frame 701 is located on the top of the limiting block 6. The filter screen 702 and the filter element 703 are respectively fixed inside the mounting frame 701. The provided filter screen 702 can filter large impurities to reduce the adsorption burden on the filter element 703. The adsorption assembly 7 is used to adsorb impurities. Two positioning rods 8 that are in contact with the adsorption assembly 7 are fixed to the bottom of the cover plate 3. The provided positioning rods 8 can squeeze the adsorption assembly 7 to fix the adsorption assembly 7. Scrapers 9 are fixed to the outer surfaces of the two positioning rods 8. The scrapers 9 are in close contact with the inner wall of the purification box 2. The provided scrapers 9 can clean the inner wall of the purification box 2. A support pad is fixed to the bottom of the base 1. An air inlet 10 is fixed to the top of the cover plate 3. A feed inlet 11 and a discharge outlet 12 are respectively fixed to the right side of the purification box 2.

[0024] Generally speaking, when the raw material moves downward due to gravity, it will be purified by the adsorption assembly 7, thus ensuring the quality of subsequent products. By providing the air inlet 10, an air compressor can be used to add high-pressure gas into the purification box 2, thereby increasing the hydraulic pressure inside the purification box 2 and further improving the purification rate.

[0025] Please refer to Figure 3 , in this embodiment, the fixing assembly 4 includes a mounting block 401, a positioning block 402, a connecting plate 403, and a return spring 404. The left and right sides of the purification box 2 are fixed to the mounting block 401. The fixing block 5 penetrates to the bottom of the mounting block 401. The positioning block 402 is slidably connected inside the mounting block 401. Sliding blocks 405 are fixed to both the upper and lower sides of the positioning block 402. Sliding grooves adapted to the sliding blocks 405 are formed inside the mounting block 401. The provided sliding blocks 405 make the movement of the positioning block 402 more stable.

[0026] Furthermore, a plug-in block 406 is fixed to the side of the sliding block 405 away from the purification box 2. A plug-in groove adapted to the plug-in block 406 is formed inside the mounting block 401. The provided plug-in block 406 can be inserted into the plug-in groove to temporarily fix the positioning block 402. An inclined surface is provided on the top of the positioning block 402. The provided inclined surface causes the positioning block 402 to be squeezed when the fixing block 5 moves downward, and the positioning block 402 is inserted into the fixing block 5 to fix the fixing block 5. Connecting plates 403 are fixed to the opposite sides of the two positioning blocks 402. A return spring 404 is fixed between the connecting plate 403 and the mounting block 401.

[0027] Generally speaking, when the fixed block 5 moves downward, it will contact the inclined surface on the positioning block 402, thereby squeezing the positioning block 402, causing the positioning block 402 to move into the interior of the mounting block 401. Thus, there is no need to manually pull the positioning block 402, making the overall operation more convenient.

[0028] The working principle of the above embodiment is as follows:

[0029] When it is necessary to clean the adsorption component 7, by pulling the connecting plate 403, the positioning block 402 and the fixed block 5 are disengaged. At this time, the fixed block 5 can move up and down. By pulling the cover plate 3 upward, the cover plate 3 can be separated from the purification box 2. When the cover plate 3 moves upward, the positioning rod 8 will lose contact with the adsorption component 7, thereby causing the adsorption component 7 to lose fixation. When the positioning rod 8 moves upward, the scraper 9 will move upward together, so that the scraper 9 can clean the inner wall of the purification box 2. After the cover plate 3 is separated from the purification box 2, the adsorption component 7 can be pulled upward to complete the disassembly of the adsorption component 7, which is convenient for cleaning the adsorption component 7. When installing the cover plate 3, when the fixed block 5 moves downward, it will contact the inclined surface on the positioning block 402, thereby squeezing the positioning block 402, causing the positioning block 402 to move into the interior of the mounting block 401. Thus, there is no need to manually pull the positioning block 402, which can effectively improve the cleaning efficiency and make the overall more practical.
