Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, and specifically to a waste gas treatment device for a thermal transfer printing machine during production. Background Art

[0002] A thermal transfer printing machine is an industrial device that uses thermal transfer technology for printing. It belongs to a new printing process. The working principle of the thermal transfer printing machine is based on advanced printing technology. Special water-based or oil-based dyes are printed on special paper to make transfer printing paper with various patterns. On the thermal transfer printing machine, after the side with the printed pattern is closely attached to the fabric to be printed, through the action of heat and pressure, the dyes undergo a sublimation effect, thereby transferring to the fabric to be printed to form various required patterns. This technology has advantages such as high precision, high speed, and wide applicability. It can print various patterns and can be printed on various materials, including cotton, linen, silk, polyester, etc. The application scenarios of the thermal transfer printing machine are very extensive, including industries such as clothing, home textiles, ceramics, plastics, etc., especially in the fashion industry and the field of home decoration.

[0003] After retrieval, in the "Waste Gas Treatment Device for a Thermal Transfer Printing Machine" with the publication number of CN216092759U, it includes a base and a printing roller group. The printing roller group includes a heating roller. The base is fixedly connected with a frame body. The heating roller is arranged inside the frame body, and both ends of the heating roller are rotationally connected to the inner wall of the frame body. A wind channel is arranged inside the frame body. The frame body is provided with an air inlet and an air outlet that are communicated with the wind channel. The frame body is rotationally connected with a loading block. The loading block is detachably connected with a number of filtering units, and one of the filtering units is communicated with the wind channel. An air extraction mechanism is arranged inside the frame body. The utility model sends the waste gas generated by the heating roller during thermal transfer into the filtering unit for filtering and then discharging it, thereby achieving the effect of green production.

[0004] In the above solution, the waste gas generated by the thermal transfer printing machine is treated and discharged through the filtering unit. However, the waste gas is only physically filtered through the filtering unit. During the thermal transfer process, many harmful gases will be volatilized due to high temperature of the coating. Simply through physical filtering, only part of the odor, particles, and impurities can be filtered out, and toxic and harmful gases and substances cannot be fully treated and filtered. As a result, there are potential safety hazards in the discharged waste gas. And because high temperature is required during the thermal transfer process, the generated waste gas has a high temperature. Therefore, when the waste gas at a relatively high temperature enters the treatment and filtering structure for a long time, it is easy to cause deformation of the filtering structure, thereby reducing the service life of the waste gas treatment device. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the present utility model is to provide an exhaust gas treatment device for thermal transfer printing machines, which has the advantage of filtering harmful substances in the exhaust gas, and solves the problem that the exhaust gas is only physically filtered by the filtering unit. During the thermal transfer process, many harmful gases will volatilize due to high temperature. Simply through physical filtration, only part of the odor, particles and impurities can be filtered out, and toxic and harmful gases and substances cannot be fully treated and filtered, thus making the discharged exhaust gas still have potential safety hazards. And because high temperature is required during the thermal transfer process, the temperature of the generated exhaust gas is relatively high. Therefore, when the relatively high temperature enters the exhaust gas treatment and filtration structure for a long time, it is easy to cause deformation of the filtration structure, and then reduce the service life of the exhaust gas treatment device.

[0006] To achieve the above object, the present utility model provides the following technical solutions.

[0013] Compared with the prior art, the present utility model provides a waste gas treatment device for a heat transfer printing machine, having the following beneficial effects:

[0014] 1. For this waste gas treatment device for a heat transfer printing machine, by arranging a plasma generator, when the positive ions and negative ions generated simultaneously by the plasma generator neutralize positive and negative charges in the air, a huge amount of energy is released instantaneously, resulting in the change or energy conversion of the surrounding bacterial structure and harmful gases, thereby causing the death of bacteria and the dissipation of toxic gases, achieving its sterilization and purification effect. Since the number of negative ions is greater than the number of positive ions, the excess negative ions still float in the air, which can achieve smoke elimination, dust removal, odor elimination, and improvement of the quality of waste gas, making the waste gas treatment of the heat transfer printing machine safer and more efficient.

[0015] 2.

When the high-temperature waste gas passes through its holes, rapid cooling can be achieved, so that during the subsequent filtration of the waste gas, high-temperature damage and aging problems to the filtration structure will not occur due to high temperature, improving the service life of the waste gas treatment device.

By inserting the filter disc 10 into the snap ring 9, it is convenient for its quick disassembly and replacement. The inside of the equalizing cooling orifice plate 8 is fixedly connected with a cold water pipe 11. Through the cold water pipe 11, the cooling water circulates, so that the temperature of the equalizing cooling orifice plate 8 is reduced. After the high-temperature exhaust gas passes through the equalizing cooling orifice plate 8, it can be cooled in time, preventing damage to the structure and accelerating aging problems caused by the high-temperature gas.

[0023] The top of the equalizing cooling orifice plate 8 is fixedly connected with a water inlet pipe 12, one end of the water inlet pipe 12 is fixedly connected to the relative end of the cold water pipe 11, the other end of the cold water pipe 11 is fixedly connected with a water outlet pipe 13, the water outlet pipe 13 is arranged at the bottom of the equalizing cooling orifice plate 8, both the water inlet pipe 12 and the water outlet pipe 13 are connected through the arc wall of the exhaust gas treatment tank 2, and sealing rings are provided at the positions where the water inlet pipe 12 and the water outlet pipe 13 penetrate through the exhaust gas treatment tank 2. One end of the water inlet pipe 12 and the water outlet pipe 13 close to the outside of the exhaust gas treatment tank 2 is fixedly connected with a circulation pump 14. The top of the circulation pump 14 is provided with a water inlet 15. A water tank is arranged inside the circulation pump 14, and a refrigeration pipe is arranged inside the water tank, which is convenient for the circulation of the cooling water, thereby cooling the high-temperature exhaust gas and preventing damage and aging inside the exhaust gas treatment tank 2 caused by the high-temperature exhaust gas.

[0024] Electromagnetic lock blocks 16 are fixedly connected to the outer arc wall positions of the relative edges of the waste gas treatment tank 2 and the tank cover 3. The two opposite electromagnetic lock blocks 16 are magnetically attracted to each other. The tank cover 3 and the waste gas treatment tank 2 are quickly locked by the electromagnetic lock blocks 16, which is convenient for subsequent cleaning, replacement and maintenance of the inside of the waste gas treatment tank 2 more conveniently and efficiently.

[0025] Embodiment 2: Refer to Figure 2 and Figure 4 , and on the basis of Embodiment 1, make further improvements:

[0026] A sealing groove 17 is provided on the connecting surface of the tank cover 3 relative to the waste gas treatment tank 2. A sealing strip 18 is fixedly connected to the connecting surface of the waste gas treatment tank 2 relative to the tank cover 3. The sealing strip 18 is adaptively inserted into the sealing groove 17. Semi-circular sealing plates 19 are fixedly connected to the bottom and top of the inner groove of the waste gas treatment tank 2. The semi-circular sealing plates 19 are mutually adapted to the inner arc of the bottom of the tank cover 3. When the tank cover 3 rotates to close the waste gas treatment tank 2, through the insertion of the sealing strip 18 and the sealing groove 17, the position of the connecting surface between the tank cover 3 and the waste gas treatment tank 2 is sealed, and the upper and lower positions of the tank cover 3 are sealed by the semi-circular sealing plates 19. Furthermore, when the tank cover 3 is closed, the waste gas treatment tank 2 can have a better sealing effect, preventing air leakage during the waste gas treatment process.

The filter disc 10 is connected to the snap ring 9 on the inner wall of the waste gas treatment tank 2 by threading the fixing bolt 20. Thus, when the tank cover 3 is opened, the filter disc 10 can stably remain in the waste gas treatment tank 2, and when the tank cover 3 is closed, the snap ring 9 on its inner arc wall can be more stably clamped to the outside of the filter disc 10.

[0028] The working principle of the present utility model is: during use, the heat transfer printing machine 1 performs production and processing. The heat transfer roller inside the body of the heat transfer printing machine 1 heat transfers the picture onto the material. During the heat transfer process, hot waste gas is generated. At this time, the air extractor 6 sucks these waste gases above the heat transfer roller. Subsequently, the waste gas enters the inside of the waste gas treatment tank 2. Then the plasma generator 7 operates to generate positive ions and negative ions to destroy and purify the bacteria and harmful gases in the waste gas. Subsequently, the purified waste gas is sucked by the exhaust pump 4 and moves upward inside the waste gas treatment tank 2. At this time, the waste gas passes through the equalizing cooling hole plate 8. The external circulating pump 14 transports the cooling water through the water inlet pipe 12 into the cold water pipe 11. The cold water pipe 11 circulates and then discharges back into the circulating pump 14 through the water outlet pipe 13 to complete the cooling water circulation. At this time, the temperature of the equalizing cooling hole plate 8 decreases, and the waste gas passing through its holes is cooled by the reduced temperature. Subsequently, it continues to rise inside the waste gas treatment tank 2, and then the waste gas passes through the filter disc 10 to filter and adsorb the particulate impurities in the waste gas, completing the purification and filtration treatment of the waste gas, realizing the waste gas treatment of the heat transfer printing machine 1. Subsequently, the waste gas is discharged outward from the exhaust pump 4 and the exhaust pipe 5.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than limiting the protection scope of the present utility model. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present utility model.
