Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically a waste gas treatment device for release film drying. Background Technology

[0002] Release film is a thin film material with low adhesion or release properties on its surface. Its core function is to prevent adhesion to other sticky substances and facilitate subsequent peeling. It is usually based on films such as PET, PE, and OPP, and achieves the release effect by coating with release agents such as silicone oil and fluorine. It is widely applicable to the processing of sticky products in the fields of electronics, packaging, and medical.

[0003] In the production process of release film, it is usually necessary to go through coating, drying and winding. In order to make the solvent or water in the coating layer evaporate quickly, the drying process often uses hot air heating or infrared heating. During this process, a certain amount of high temperature waste gas will be generated, which may contain water vapor, solvent components and some particulate impurities.

[0004] The waste gas generated during the drying of release film is discharged directly without treatment, which will affect the surrounding environment and pose safety hazards. For example, some organic solvents are flammable and explosive. Long-term discharge of high-temperature waste gas will also have an adverse effect on the production workshop environment and equipment stability, affecting the subsequent processing and production of release film.

[0005] Therefore, a release film drying exhaust gas treatment device is proposed to address the above problems. Utility Model Content

[0023] 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 scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a release film drying exhaust gas treatment device includes an exhaust gas treatment box 1, a connecting pipe 11 fixedly connected to the side wall of the exhaust gas treatment box 1, a treatment hood 12 connected to the end of the connecting pipe 11, a cover plate 13 provided inside the exhaust gas treatment box 1, a plurality of first baffles 14 fixedly connected inside the exhaust gas treatment box 1, a plurality of second baffles 16 fixedly connected inside the exhaust gas treatment box 1, and a centrifugal fan 15 fixedly connected to the side wall of the exhaust gas treatment box 1. After the release film is dried by the drying device, the treatment hood 12 can be fitted onto the release film drying device. After the fitting is completed, the second baffles 16 can be activated, and then the second baffles 16 will draw air into the exhaust gas treatment box 1, thereby creating a negative pressure inside the exhaust gas treatment box 1. Then, the air drawn by the second baffles 16 will enter the treatment hood 12 through the connecting pipe 11. The exhaust gas generated by the release film drying device, which is then covered by the treatment hood 12, is drawn into the exhaust gas treatment box 1. Inside the exhaust gas treatment box 1, the exhaust gas comes into contact with the second baffle 16, and then with the first baffle 14. Finally, it is discharged outside the exhaust gas treatment box 1 through the centrifugal fan 15. As the exhaust gas is blocked by the first baffle 14 and the centrifugal fan 15, impurities and dirt in the exhaust gas are adsorbed onto the surfaces of the first baffle 14 and the second baffle 16. By adding the first baffle 14 and the second baffle 16, dust and impurities in the exhaust gas can be removed, reducing the likelihood of dust and impurities in the exhaust gas negatively impacting the production workshop environment and equipment stability. Simultaneously, adding the treatment hood 12 allows the drying device to be completely enclosed, reducing the possibility of exhaust gas not being fully discharged.

[0026] like Figures 1 to 3 As shown, the exhaust gas treatment box 1 has a placement slot 21 inside; a rotating rod 22 is rotatably installed inside the placement slot 21; a pendulum 2 is fixedly connected to the end of the rotating rod 22; when impurities on the exhaust gas are adsorbed onto the surfaces of the first baffle 14 and the second baffle 16, dust and impurities will be adsorbed onto the surface due to electrostatic attraction. When the centrifugal fan 15 generates a negative pressure effect inside the exhaust gas treatment box 1, the pendulum 2 will rotate inside the placement slot 21. At this time, the pendulum 2 will knock the first baffle 14 and the second baffle 16, and the dust and impurities adsorbed onto the surfaces of the first baffle 14 and the second baffle 16 can be knocked away. By adding the pendulum 2, the dust and impurities adsorbed onto the surfaces of the first baffle 14 and the second baffle 16 can be removed, reducing the situation where dust and impurities are adsorbed onto the surfaces of the first baffle 14 or the second baffle 16 and are inconvenient to remove later, thus improving the cleanliness of the surfaces of the first baffle 14 and the second baffle 16.

[0027] like Figures 1 to 4As shown, a collection box 3 is provided inside the exhaust gas treatment box 1; the collection box 3 is located on the side of the first baffle 14 and the second baffle 16; a square groove 32 is opened inside the collection box 3; a pull rope 31 is fixed inside the square groove 32; when the dust and impurities on the surface of the first baffle 14 and the second baffle 16 are knocked off, the dust and impurities will fall into the collection box 3, and the collection box 3 will collect the dust and impurities. When enough dust and impurities have been collected inside the collection box 3, the pull rope 31 can be pulled, and then the collection box 3 will be pulled out from inside the exhaust gas treatment box 1. After being pulled out, the collected dust and impurities can be processed; by adding the collection box 3, the dust and impurities that have been processed off the surface of the first baffle 14 and the second baffle 16 can be collected, reducing the accumulation of dust and impurities inside the exhaust gas treatment box 1.

[0028] like Figure 2 As shown, a support plate 41 is fixedly connected to the side wall of the processing cover 12; a suction cup 4 is fixedly connected to the bottom of the support plate 41; when the processing cover 12 covers the drying device, the suction cup 4 will contact the ground, and the suction cup 4 can increase the stability of the processing cover 12 after covering the drying device; by adding the suction cup 4, the processing cover 12 can more firmly cover the drying device, reducing the shaking of the processing cover 12 when covering the drying device due to the negative pressure effect of the centrifugal fan 15.

[0029] like Figure 5 As shown, the suction cup 4 is equipped with a rotating ball bearing 5 inside; there are multiple balls bearing 5 inside the suction cup 4; when the suction cup 4 comes into contact with the ground and adsorbs, the balls bearing 5 will increase the contact area with the ground; by increasing the balls bearing 5, the suction cup 4 can more firmly cover the treatment cover 12, reduce the shaking of the suction cup 4, and improve the fixation stability of the suction cup 4.

[0030] like Figure 5 As shown, a filter screen 6 is fixedly connected inside the connecting pipe 11; multiple filter screens 6 are provided; when the exhaust gas is drawn out from inside the connecting pipe 11 by the centrifugal fan 15, larger impurities next to the drying device will be filtered by the filter screen 6; by adding filter screens 6, the situation of larger impurities entering the exhaust gas treatment box 1 can be reduced, and the situation of blockage in the connecting pipe 11 can be reduced.

[0031] Working principle: After the release film is dried using the drying device, the processing cover 12 can be placed on the release film drying device. After placement, the second baffle 16 can be activated, which will then draw air into the exhaust gas treatment box 1, creating a negative pressure inside. The air drawn by the second baffle 16 will then enter the processing cover 12 through the connecting pipe 11. Subsequently, the exhaust gas generated by the release film drying device, which is covered by the processing cover 12, will be drawn into the exhaust gas treatment box 1. At this point, the exhaust gas will be treated in the exhaust gas treatment box 1. The gas enters through the first baffle 14 and then contacts the second baffle 16. Finally, it is discharged to the outside of the exhaust gas treatment box 1 by the centrifugal fan 15. As the exhaust gas is blocked by the first baffle 14 and the centrifugal fan 15, impurities and dirt in the exhaust gas are adsorbed onto the surfaces of the first baffle 14 and the second baffle 16. After the impurities are adsorbed onto the surfaces of the first baffle 14 and the second baffle 16, dust and impurities are attracted to the surfaces due to electrostatic attraction. The centrifugal fan 15 then processes the exhaust gas. When a negative pressure is generated inside box 1, the pendulum 2 will rotate inside the placement slot 21. At this time, the pendulum 2 will strike the first baffle 14 and the second baffle 16, knocking away the dust and impurities adsorbed on their surfaces. After the dust and impurities on the surfaces of the first baffle 14 and the second baffle 16 are knocked away, they will fall into the collection box 3, which will collect them. Once enough dust and impurities have been collected in the collection box 3, the pull rope 3 can be pulled. 1. Then, pull the rope 31 to pull the collection box 3 out from the inside of the exhaust gas treatment box 1. After being pulled out, the collected dust and impurities can be processed. When the treatment cover 12 covers the drying device, the suction cup 4 will come into contact with the ground. The suction cup 4 can increase the stability of the treatment cover 12 after it covers the drying device. When the suction cup 4 comes into contact with the ground and adsorbs, the ball 5 will increase the contact area with the ground. When the exhaust gas is drawn out from the inside of the connecting pipe 11 by the centrifugal fan 15, the larger impurities next to the drying device will be filtered by the filter screen 6.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
