[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figures 1 to 3As shown, one embodiment of this utility model is provided: an air purification device for modified plastic production, including a mounting frame 1. An air suction component for drawing in air is fixedly connected inside the mounting frame 1. The air suction component includes a baffle 2, which is fixedly connected to the outside of the mounting frame 1. The baffle 2 can prevent foreign objects from entering the inside of the mounting frame 1. A fan 3 is fixedly connected inside the mounting frame 1. The fan 3 can generate sufficient suction to quickly draw out the waste gas generated during the production of modified plastics, ensuring the efficiency of waste gas purification. A sliding groove 4 is provided on the outside of the mounting frame 1. The sliding groove 4 provides a track for the sliding of an outer ring 5. The outer ring 5 is slidably connected inside the sliding groove 4.
[0032] The outer ring 5 is externally slidably connected to the inside of the mounting frame 1, and the activated carbon plate 6 is externally slidably connected to the inside of the chute 4. The activated carbon plate 6 has good adsorption performance and can effectively remove harmful impurities and odors from the exhaust gas. The activated carbon plate 6 is installed inside the outer ring 5, and the outer ring 5 provides a mounting carrier for the activated carbon plate 6. The activated carbon plate 6 is externally slidably connected to the inside of the mounting frame 1 to ensure that the activated carbon plate 6 performs the best purification effect during operation.
[0033] The limiting block 12 is externally slidably connected to the inside of the pulling block 7. The external ring 5 is externally fixedly connected to the pulling block 7. The pulling block 7 facilitates the extraction and insertion of the external ring 5. The mounting frame 1 is externally fixedly connected to the fixing plate 8. The top of the fixing plate 8 is slidably connected to two sliding rods 9. The sliding rods 9 slide smoothly on the fixing plate 8. The top of the sliding rods 9 is fixedly connected to the top plate 10. The top plate 10 can effectively prevent the sliding rods 9 from coming off the fixing plate 8. The outside of the sliding rods 9 is fitted with a spring 11. The spring 11 can push the limiting block 12. One side of the spring 11 is fixedly connected to the bottom of the fixing plate 8, and the other side of the spring 11 is fixedly connected to the top of the limiting block 12. The bottom of the two sliding rods 9 is fixedly connected to the limiting block 12. The limiting block 12 is adapted to the inside of the pulling block 7 and can be accurately locked into the pulling block 7 under the action of the spring 11, reliably limiting the external ring 5 and preventing it from accidentally sliding out during use.
[0034] Reference Figure 1 and Figure 4 As shown, a through groove 13 is provided at the bottom of the mounting frame 1, and a bottom ring 14 is fixedly connected to the bottom of the mounting frame 1. The bottom ring 14 is tightly connected to the mounting frame 1, and the outside of the bottom ring 14 is slidably connected to the inside of the ventilation pipe 18, which can achieve quick docking during installation. The bottom of the retaining ring 15 contacts the top of the ventilation pipe 18, and the outside of the bottom ring 14 is fixedly connected to the retaining ring 15. The retaining ring 15 can fit tightly with the top of the ventilation pipe 18. A sealing groove 16 is provided inside the retaining ring 15, and a sealing ring 17 is slidably connected inside the sealing groove 16.
[0035] The sealing ring 17 can form a good seal between the retaining ring 15 and the ventilation pipe 18, effectively preventing gas leakage. The bottom of the sealing ring 17 is fixedly connected to the ventilation pipe 18. Two retaining grooves 19 are opened on the outside of the retaining ring 15. Two connecting blocks 20 are fixedly connected to the outside of the ventilation pipe 18. The connection between the connecting blocks 20 and the ventilation pipe 18 is firm. A rotating block 21 is rotatably connected inside the connecting block 20. A retaining block 22 is fixedly connected to the outside of the rotating block 21. The outside of the retaining block 22 engages with the inside of the retaining groove 19. Through the cooperation of the rotating block 21 and the retaining groove 19, the sealing performance and stability of the entire device during operation are ensured. The outside of the sealing ring 17 is slidably connected to the inside of the retaining ring 15 to achieve a good sealing effect.
[0036] Working principle: When purifying the waste gas generated during the production of modified plastics, the operator first tightly connects the ventilation pipe 18 to the mounting frame 1, then starts the fan 3. The fan 3 drives the gas discharged during the production of modified plastics inside the ventilation pipe 18, drawing it through the activated carbon plate 6 inside the outer ring 5. The activated carbon plate 6 then purifies the drawn-in waste gas. When it is necessary to quickly replace the activated carbon plate 6 inside the outer ring 5, simply move the limit block 12 upwards. Then, the limiting block 12 slides out from the inside of the pulling block 7. Then, by holding the pulling block 7 and pulling it, the pulling block 7 drives the outer ring 5 and the activated carbon plate 6 to slide out from the inside of the slide groove 4. Then, the activated carbon plate 6 is replaced. After the replacement is completed, the outer ring 5 and the activated carbon plate 6 are slid back into the inside of the slide groove 4. Then, the limiting block 12 is released, so that the spring 11 pushes the limiting block 12, so that the limiting block 12 slides between the pulling block 7 and the outer ring 5 for limiting treatment, preventing the outer ring 5 from sliding out during use.
[0037] Then, when connecting the ventilation pipes 18 with the mounting frame 1, simply slide the mounting frame 1 with the bottom ring 14 and the retaining ring 15 on the top of the ventilation pipe 18, and then let the sealing ring 17 slide inside the sealing groove 16 between the retaining ring 15 and the bottom ring 14, so that the sealing ring 17 is engaged inside the sealing groove 16. Then rotate the rotating block 21, so that the rotating block 21 and the retaining block 22 engage with the retaining groove 19, so that the bottom ring 14 and the retaining ring 15 are tightly connected to the ventilation pipe 18, preventing gas leakage.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
