Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of textiles, in particular to a waste gas cold zone collecting device for textile cloth transfer printing and a transfer printing equipment. BACKGROUND

[0002] At present, in the process of textile production, various different patterns need to be transferred to the textile fabric to obtain a variety of different pattern layers of textile fabric to meet the needs of different consumers.

[0003] In the transfer printing process, the designed transfer printing pattern layer is usually printed on the transfer paper first, and then the transfer paper is processed by the transfer printing equipment to transfer the transfer printing pattern layer to the textile cloth, thereby realizing the transfer printing process of the pattern. However, due to the volatile oily printing oil contained in the transfer printing pattern layer printed on the transfer paper, the transfer printing pattern layer is easy to emit a large amount of smoke under high temperature processing conditions, thereby polluting the environment and causing great pressure on the environment.

[0004] In order to remove these smokes, an air extraction assembly and a filter plate are usually added to the transfer printing equipment to achieve the effect of purifying air. For example, in the patent CN213555963U, a waste gas collecting and processing device for a heat transfer printing equipment is disclosed, which specifically discloses an air extraction assembly 3 on the heat transfer printing machine body 1 and a conveying pipe 4 fixed to the rack 2. The air extraction assembly 3 is provided with a clean gas pipe 5, and two groups of conveying belts one 6 are symmetrically arranged in the clean gas pipe 5. The filter plate 7 is slidably arranged on the two groups of conveying belts one 6. That is, the waste gas generated by the heat transfer printing machine is extracted into the clean gas pipe by starting the air extraction assembly. The waste gas entering the clean gas pipe will pass through the switching assembly and then be discharged into the atmosphere after being filtered by the filter plate.

[0005] However, in the transfer printing process, the volatile oily gas contained in the large amount of smoke emitted is easy to flow into the atmosphere from the multiple filter holes on the filter plate, thereby reducing the filtering effect of the filter plate on the waste gas, that is, the recovery rate of the volatile oily gas by the conventional waste gas collecting and processing device is low, and the collecting effect is poor. SUMMARY

[0006] The present application aims to overcome the shortcomings of the prior art, and provides a waste gas cold zone collecting device for textile cloth transfer printing and a transfer printing equipment, which has a high recovery rate of volatile oily gas, a good waste gas collecting effect, and can recover a volatile oily liquid with high purity.

[0041] In order to better understand the technical solutions and beneficial effects of the present application, the present application will be further described in detail below in combination with specific embodiments:

[0042] Please refer to Figures 1 to 3The waste gas cooling device 10 for textile fabric transfer in an embodiment comprises a support 100, a waste gas collecting assembly 200, a waste gas cooling assembly 300, a waste gas pumping assembly (not shown in the figure) and a waste oil filtering and pumping assembly 400. The waste gas collecting assembly 200 comprises a collecting pipe 210 and a pumping tank 220 connected in communication, the collecting pipe 210 is arranged on the support 100, the collecting pipe 210 is provided with a collecting part 2121, the collecting part 2121 is formed with an opening 2121a and a cavity 2121b connected in communication, the cavity 2121b is used for collecting the waste gas generated during the textile fabric transfer. The waste gas cooling assembly 300 comprises a waste gas cooling part 310 and a cooling pipe 320, the cooling pipe 320 comprises a liquid inlet pipe 321, a cooling main pipe 322 and a liquid outlet pipe 323 connected in communication in sequence, the cooling main pipe 322 is arranged transversely in the cavity 2121b, and the liquid inlet pipe 321 and the liquid outlet pipe 323 are both located outside the collecting pipe 210; the waste gas cooling part 310 is arranged in the cavity 2121b and located below the cooling main pipe 322. The pumping tank 220 is provided with an air outlet 221, the waste gas pumping assembly is connected in communication with the air outlet 221, and the waste gas pumping assembly can pump the waste gas generated during the textile fabric transfer into the pumping tank 220. The waste oil filtering and pumping assembly 400 comprises a filtering plate 410 and a pumping part 420, the filtering plate 410 and the pumping part 420 are arranged in the pumping tank 220 in sequence.

[0043] The waste gas cold area collecting device 10 for textile fabric transfer printing described above, since the collecting pipe 210 is arranged on the support 100 to realize the fixation of the collecting pipe 210, and since the collecting pipe 210 is provided with the collecting part 2121 which is formed with the opening 2121a and the cavity 2121b which are communicated, the extraction tank 220 is provided with the extraction opening which is communicated with the waste gas extraction assembly, when the waste gas extraction assembly is normally operated, the waste gas generated during the textile fabric transfer printing can be extracted from the opening 2121a into the cavity 2121b, and the cooling main pipe 322 is arranged transversely in the cavity 2121b, so that the cooling main pipe 322 can be distributed in the cavity 2121b with a larger area, so that the waste gas entering the cavity 2121b can be contacted with the cooling main pipe 322 with a larger area, when the cooling liquid enters from the liquid inlet pipe 321 and then flows out from the liquid outlet pipe 323, the volatile oily gas contained in the waste gas can be rapidly cooled into liquid and attached to the outer side wall of the cooling main pipe 322 when the volatile oily gas is contacted with the cooling main pipe 322, and since the waste gas cold area collecting piece 310 is arranged in the cavity 2121b and is located below the cooling pipe 320, the liquid attached to the outer side wall of the cooling main pipe 322 can fall on the waste gas cold area collecting piece 310 when the liquid accumulates to a certain weight, when the liquid of the waste gas cold area collecting piece 310 accumulates to a certain amount, the liquid can flow from the waste gas cold area collecting piece 310 to the filter plate 410 in the extraction tank 220 under the action of gravity, then flows into the suction piece 420 through the filter plate 410, and finally is absorbed by the suction piece 420, so as to realize the recovery of the volatile oily gas in the waste gas, which not only improves the recovery rate of the volatile oily gas, but also has a good effect on the collection of the waste gas, that is, the gas cooled by the cooling main pipe 322 can be collected in the extraction tank 220, so as to effectively avoid the pollution of the air in the transfer printing process workshop by the waste gas, and thus the air quality in the transfer printing process workshop is ensured. In addition, a volatile oily liquid with high purity can be obtained.

[0044] Please refer to Figure 3 In other embodiments, the collecting pipe 210 comprises a branch pipe 211, a horizontal elbow pipe 212 and a vertical elbow pipe 213 which are communicated in sequence, the branch pipe 211 is formed with an air inlet end 2111, the collecting part 2121 is arranged on the horizontal elbow pipe 212, and the vertical elbow pipe 213 is communicated with the extraction tank 220. It can be understood that since the branch pipe 211, the horizontal elbow pipe 212 and the vertical elbow pipe 213 can form two bending parts, the distribution of the collecting pipe 210 in the transfer printing equipment area can be improved, and thus the collection area of the waste gas and the recovery rate of the volatile oily gas are improved.

[0045] In another embodiment, the extending direction of the branch pipe 211 and the extending direction of the transverse bend 212 form an angle, so that the air inlet end 2111 of the branch pipe 211 and the collection part 2121 of the transverse bend 212 can intersect each other. This allows exhaust gas to enter the cavity 2121b from multiple different directions, achieving more comprehensive collection of exhaust gas. Further, the angle is 25°~75°, so that the upward angle of the branch pipe 211 is not too large, allowing exhaust gas to enter the cavity 2121b smoothly from the air inlet end 2111. Further, the branch pipe 211 is provided with a bend, allowing exhaust gas to enter the cavity 2121b even more smoothly from the air inlet end 2111.

[0046] Please see Figure 3 In another embodiment, the opening 2121a of the collection section 2121 is disposed toward the transfer worktable 600 of the transfer device, so that the opening 2121a can effectively collect the exhaust gas of the transfer worktable 600, so that the exhaust gas can better enter the outer peripheral wall of the cooling pipe 322.

[0047] In this embodiment, the extension direction of the transverse bend 212 is parallel to the horizontal plane to achieve a transverse arrangement of the transverse bend 212. In another embodiment, there are multiple openings 2121a, which are spaced apart on the collection part 2121 so that the exhaust gas can be divided into multiple airflows from the collection part 2121 into the cavity 2121b. That is, the multiple openings 2121a can disperse the exhaust gas in the collection part 2121 into multiple airflows into the cavity 2121b, so that the exhaust gas can be quickly and well dispersed on the outer peripheral wall of the cooling pipe 322. This ensures that the exhaust gas entering the cavity 2121b can fully and comprehensively contact the cooling pipe 322, so that the cooling pipe 322 can better cool the volatile oily gas in the cavity 2121b into liquid, thereby improving the recovery rate of volatile oily gas in the exhaust gas.

[0048] Please see Figure 2 , Figure 3In another embodiment, the air inlet 2111 is located at the end of the branch pipe 211 away from the transverse bend 212. It can be understood that because multiple openings 2121a are spaced apart on the collection section 2121, the amount of exhaust gas in the cavity 2121b corresponding to the spaces between the multiple openings 2121a is relatively small, resulting in less exhaust gas contacting the outer wall of the cooling main pipe 322, and consequently, a lower utilization rate of the cooling main pipe 322. Therefore, this application sets the air inlet 2111 at the end of the branch pipe 211 away from the transverse bend pipe 212, so that the exhaust gas can flow laterally through the cooling main pipe 322 after entering from the air inlet 2111. At the same time, the exhaust gas entering through the multiple openings 2121a of the transverse bend pipe 212 can make the exhaust gas fully contact the cooling main pipe 322, thereby ensuring that the outer peripheral wall of the cooling main pipe 322 is in contact with the exhaust gas. In this way, not only is the utilization rate of the cooling main pipe 322 improved, but the recovery rate of volatile oily gases is also improved.

[0049] Please see Figure 2 , Figure 3 In another embodiment, the length of the collection section 2121 is less than the length of the cooling main pipe 322. It is understood that if the length of the collection section 2121 is greater than the length of the cooling main pipe 322, some exhaust gas entering the cavity 2121b from the collection section 2121 may miss the cooling main pipe 322, thus failing to ensure that all the exhaust gas entering the cavity 2121b can contact the cooling main pipe 322, thereby reducing the recovery rate of volatile oily gases in the exhaust gas. Therefore, the length of the collection section 2121 is less than the lateral length of the cooling main pipe 322 to ensure that the exhaust gas entering the cavity 2121b from the collection section 2121 can fully contact the cooling main pipe 322, thereby improving the recovery rate of volatile oily gases in the exhaust gas.

[0050] In another embodiment, a plurality of openings 2121a are arranged sequentially along the length of the collection section 2121 to achieve multi-stream diversion of the exhaust gas.

[0051] Furthermore, in another embodiment, the size of the plurality of openings 2121a gradually decreases from the end furthest from the extraction tank 220 to the end closest to the extraction tank 220. It is understood that if a large amount of waste gas is drawn into the openings 2121a of the collection section 2121, the cooling main pipe 322 may not be able to effectively and quickly cool the large amount of waste gas drawn in at once, thus easily resulting in a low recovery rate of volatile oily gases in the waste gas. Therefore, this application arranges multiple openings 2121a sequentially along the length of the collection section 2121, with the size of the multiple openings 2121a gradually decreasing from the end away from the extraction tank 220 to the end closer to the extraction tank 220. This allows the waste gas to form a stepped, graded inflow in the collection section 2121, meaning that the waste gas inflow from the collection section 2121 near the liquid inlet pipe 321 gradually decreases towards the collection section 2121 away from the liquid inlet pipe 321. This stepped, graded inflow can better match the temperature difference of the coolant in the cooling main pipe 322, thereby achieving sufficient and comprehensive cooling of the incoming waste gas and improving the recovery rate of volatile oily gases in the waste gas by the cooling main pipe 322. Furthermore, the stepped flow rate enables continuous replenishment of waste gas during cooling. Simultaneously, it coordinates with the waste gas flow rate at the inlet end 2111 of the branch pipe 211 to ensure that the waste gas entering the cavity 2121b is fully cooled by the cooling main pipe 322. This not only improves the utilization rate of the cooling area of ​​the cooling main pipe 322, but also increases the recovery rate of volatile oily gases in the waste gas, thereby achieving energy conservation and environmental protection in transfer printing production.

[0052] In some other embodiments, the length of the plurality of openings 2121a arranged in the collection section 2121 is no greater than 2 / 3 of the length of the cooling main pipe 322. It is understood that if the length of the plurality of openings 2121a arranged in the collection section 2121 is greater than 2 / 3 of the length of the cooling main pipe 322, the path of the exhaust gas entering from the last opening 2121a of the collection section 2121 through the cooling main pipe 322 is shorter. This makes it impossible to ensure that the cooling main pipe 322 can adequately and comprehensively cool the exhaust gas entering from the last opening 2121a of the collection section 2121, resulting in poor cooling effect and a low recovery rate of volatile oily gases. Therefore, this application ensures that the length of the arrangement of the multiple openings 2121a in the collection section 2121 is no greater than 2 / 3 of the length of the cooling main pipe 322, so that the cooling main pipe 322 can fully and comprehensively cool the exhaust gas entering from the last opening 2121a of the collection section 2121, thereby improving the recovery rate of volatile oily gases.

[0053] In some other embodiments, the cooling main pipe 322 is inclined within the cavity 2121b. It is understood that by inclinedly positioning the cooling main pipe 322 within the cavity 2121b, a slope difference is created within the cavity 2121b, allowing coolant to quickly enter the cooling main pipe 322 from the inlet pipe 321 and flow out from the outlet pipe 323, thereby improving the circulation flow of the coolant and better ensuring the cooling effect of the cooling main pipe 322.

[0054] Please see Figure 3 In some other embodiments, the cooling main pipe 322 is arranged to gradually slope downwards from the distance from the extraction tank 220 towards the distance from the extraction tank 220. It can be understood that by arranging the cooling main pipe 322 to gradually slope downwards from the distance from the extraction tank 220 towards the distance from the extraction tank 220, so that the end away from the extraction tank 220 is the inlet pipe 321 and the end near the extraction tank 220 is the outlet pipe 323, this not only achieves the inclined arrangement of the cooling main pipe 322 and the cavity 2121b, allowing the coolant to flow quickly from the inlet pipe 321 to the outlet pipe 323, but also ensures a high flow velocity of the coolant within the cooling main pipe 322, thereby ensuring that the cooling main pipe 322 has a good cooling effect on the volatile oily gases in the exhaust gas.

[0055] It is worth mentioning that, since the cooling temperature of the inlet pipe 321 is relatively lower than that of the outlet pipe 323, the cooling main pipe 322 closer to the inlet pipe 321 has a better cooling effect than the cooling main pipe 322 farther from the inlet pipe 321. Furthermore, since the exhaust gas cooling path is from the inlet pipe 321 to the outlet pipe 323, in order to improve the cooling utilization rate of the cooling main pipe 322, this application sets the cooling main pipe 322 to gradually slope downwards from away from the extraction tank 220 towards the extraction tank 220, and multiple of the... The size of the opening 2121a gradually decreases from the end away from the extraction tank 220 to the end closer to the extraction tank 220, so as to ensure that the inflow of exhaust gas into the cooling main pipe 322 near the liquid inlet pipe 321 is relatively large. In this way, the cooling main pipe 322 near the liquid inlet pipe 321 can better cool more exhaust gas. Then, when the exhaust gas flows through the cooling main pipe 322, the cooling main pipe 322 can cool the exhaust gas better and more completely, which not only improves the cooling utilization rate of the cooling main pipe 322, but also improves the recovery rate of volatile oily gases.

[0056] In some other embodiments, the angle between the cooling main pipe 322 and the cavity 2121b is 5° to 15°. This ensures that the slope between the cooling main pipe 322 and the cavity 2121b is between 5° and 15°, thereby ensuring a moderate coolant flow rate and avoiding poor cooling utilization due to excessively fast coolant flow.

[0057] Please see Figure 3 , Figure 6 and Figure 7 In some other embodiments, the exhaust gas cold zone collector 310 is inclinedly disposed within the cavity 2121b, and one end of the exhaust gas cold zone collector 310 forms an abutment portion 324 with the first sidewall of the cavity 2121b. It can be understood that by inclinedly disposing the exhaust gas cold zone collector 310 within the cavity 2121b, the liquid collected in the exhaust gas cold zone collector 310 can flow more quickly into the extraction tank 220 under the influence of gravity, thereby achieving the recovery of volatile oily gases from the exhaust gas. Furthermore, since one end of the exhaust gas cold zone collector 310 forms an abutment portion 324 with the first side wall of the cavity 2121b, the liquid collected by the exhaust gas cold zone collector 310 can flow better along the side wall of the vertical bend 213 into the filter plate 410 in the extraction tank 220. This effectively avoids the phenomenon of liquid on the exhaust gas cold zone collector 310 falling directly into the filter plate 410 and causing secondary splashing, which would result in liquid loss and a decrease in the recovery rate of volatile oily gases.

[0058] Please see Figure 7 In this embodiment, one end of the exhaust gas cooling zone collector 310 forms an abutment portion 324 with the first sidewall of the cavity 2121b, and the other end of the exhaust gas cooling zone collector 310 is connected to the second sidewall of the cavity 2121b, thereby fixing the exhaust gas cooling zone collector 310 within the cavity 2121b. Furthermore, the second sidewall of the cavity 2121b is provided with a hanging rope or fixing frame 500, and the other end of the exhaust gas cooling zone collector 310 is connected to the second sidewall of the cavity 2121b via the hanging rope or fixing frame 500, thereby fixing the exhaust gas cooling zone collector 310 to the sidewall of the cavity 2121b.

[0059] In some other embodiments, the angle between the waste gas cooling zone collector 310 and the cavity 2121b is 10° to 30°. It can be understood that by setting the angle between the waste gas cooling zone collector 310 and the cavity 2121b to 10° to 30°, a good slope is maintained between them, allowing liquid on the waste gas cooling zone collector 310 to flow quickly from the collector to the drainage channel 2131. This avoids excessive liquid accumulation on the waste gas cooling zone collector 310, which could cause liquid to fall onto the side wall of the horizontal bend 212, thereby improving the recovery rate of volatile oily gases.

[0060] It should be noted that the angle at which the exhaust gas cooling zone collector 310 is inclined relative to the cavity 2121b is greater than the angle at which the cooling main pipe 322 is inclined relative to the cavity 2121b. This results in the exhaust gas cooling zone collector 310 being closer to the liquid inlet pipe 321, meaning the distance between the exhaust gas cooling zone collector 310 and the liquid inlet pipe 321 is relatively short. This allows the liquid on the outer wall of the cooling main pipe 322 to drip more effectively onto the exhaust gas cooling zone collector 310. It is worth mentioning that because the cooling main pipe 322 near the liquid inlet pipe 321 has a better cooling effect and receives more exhaust gas, a larger amount of liquid forms on the outer wall of the cooling main pipe 322 near the liquid inlet pipe 321. Therefore, by positioning the exhaust gas cooling zone collector 310 relatively close to the cooling main pipe 322 of the liquid inlet pipe 321, the exhaust gas cooling zone collector 310 can better collect the liquid near the cooling main pipe 322 near the liquid inlet pipe 321, effectively preventing liquid splashing and loss.

[0061] In some other embodiments, the cross-section of the exhaust gas cooling zone collector 310 is tile-shaped. It is understood that because the tile-shaped exhaust gas cooling zone collector 310 has a better collection effect, the sidewalls on both sides of the exhaust gas cooling zone collector 310 can effectively prevent liquid from splashing and leaking, thereby improving the liquid recovery rate.

[0062] Please see Figure 4 , Figure 5 In some other embodiments, the exhaust gas cooling zone collection component 310 includes a first collection plate 311 and a second collection plate 312 connected together, the first collection plate 311 and the second collection plate 312 being connected at an angle. It can be understood that because the first collection plate 311 and the second collection plate 312 are connected at an angle, they can be connected to form a tile-like structure to collect liquid from the outer wall of the cooling main pipe 322.

[0063] Please see Figure 4 , Figure 5In some other embodiments, the included angle formed by the connection of the first collecting plate 311 and the second collecting plate 312 is an obtuse angle. It can be understood that because the included angle between the first collecting plate 311 and the second collecting plate 312 is an obtuse angle, on the one hand, it ensures that the collecting cavity 314 has a large collecting capacity, and on the other hand, it ensures that the opening angle of the collecting cavity 314 is large, so as to better receive the liquid falling from the outer peripheral wall of the cooling pipe 322. At the same time, the first collecting plate 311 and the second collecting plate 312 can also effectively prevent liquid splashing and loss, thereby improving the liquid recovery rate. Please refer to... Figure 5 To improve the liquid recovery rate of the exhaust gas cooling zone collector 310, in some other embodiments, the first collecting plate 311 and the second collecting plate 312 are connected to form a collecting cavity 314, the cooling main pipe 322 is located within the collecting cavity 314, and the cooling main pipe 322 at least partially protrudes from the collecting cavity 314. It is understood that if the cooling main pipe 322 is entirely located within the collecting cavity 314, exhaust gas will enter the outer wall of the cooling main pipe 322 more slowly, thus affecting the cooling effect of the cooling main pipe 322 on volatile oily gases, and also resulting in poorer dispersion and diversion effects on the exhaust gas. Therefore, this application provides a method by having the cooling pipe 322 protrude into the collection chamber 314, allowing the protruding cooling pipe 322 to contact the exhaust gas in the chamber 2121b more quickly. At the same time, the protruding cooling pipe 322 can disperse the exhaust gas into multiple streams that come into contact with the cooling pipe 322, thereby ensuring that the exhaust gas entering the chamber 2121b can contact the cooling pipe 322 more fully and comprehensively, so as to achieve a better cooling effect on the exhaust gas and thus improve the recovery rate of volatile oily gases in the exhaust gas.

[0064] To prevent the exhaust gas cold zone collector 310 from blocking exhaust gas from entering the cooling main pipe 322, please refer to... Figure 5 In some other embodiments, the height of the first collecting plate 311 is less than the height of the second collecting plate 312, and the first collecting plate 311 is positioned towards the opening 2121a. It can be understood that because the height of the first collecting plate 311 is less than the height of the second collecting plate 312, the exhaust gas cooling zone collection component 310 can form an irregular tile shape. Furthermore, because the first collecting plate 311 is positioned towards the opening 2121a, the exhaust gas can smoothly enter the cooling main pipe 322, ensuring that the cooling main pipe 322 can provide a better cooling effect for the exhaust gas.

[0065] To ensure that exhaust gas can smoothly enter the cooling main pipe 322 and at the same time to prevent liquid falling from the outer peripheral wall of the cooling main pipe 322 from splashing and leaking out, please refer to... Figure 5In some other embodiments, the exhaust gas cold zone collector 310 further includes a bending avoidance member 313, which is connected to the first collection piece 311, and the bending avoidance member 313 and the first collection piece 311 are connected to form an acute angle. It is understood that by adding a bending avoidance member 313 to the first collection plate 311, and the bending avoidance member 313 connecting with the first collection plate 311 to form an acute angle, the bending avoidance member 313 can be inclined to the first collection plate 311. This ensures that the inclined bending avoidance member 313 will not block the exhaust gas from entering the cooling main pipe 322. At the same time, the bending avoidance groove formed by the connection between the bending avoidance member 313 and the first collection plate 311 can not only increase the collection capacity of the collection cavity 314, but also effectively prevent the liquid falling from the outer peripheral wall of the cooling main pipe 322 from splashing and leaking. Thus, it ensures that the exhaust gas can smoothly enter the cooling main pipe 322 while ensuring that the liquid falling from the outer peripheral wall of the cooling main pipe 322 is not prone to splashing and leaking.

[0066] In some other embodiments, the bending avoidance member 313, the first collecting piece 311 and the second collecting piece 312 are integrally formed to ensure that there is no gap between the bending avoidance member 313, the first collecting piece 311 and the second collecting piece 312, thereby avoiding leakage when the exhaust gas cold zone collecting member 310 collects liquid, and thus improving the liquid recovery rate.

[0067] Please see Figure 5 In some other embodiments, a collection flow channel 315 is formed at the connection between the first collection plate 311 and the second collection plate 312. The collection flow channel 315 is used to collect liquid falling from the outer peripheral wall of the cooling main pipe 322, so that the collected liquid can gather in the collection flow channel 315 and flow into the diversion channel 2131 through the collection flow channel 315, so that the collected liquid can flow quickly to the diversion channel 2131, and then flow into the suction member 420 in the extraction tank 220 through the diversion channel 2131, thereby achieving rapid collection of liquid, while avoiding the phenomenon that too much liquid accumulates on the waste gas cooling zone collection member 310 and easily causes liquid to escape, thereby improving the recovery of liquid. To ensure that the liquid on the outer peripheral wall of the cooling main pipe 322 falls effectively into the collection flow groove 315, in some other embodiments, a guide member is provided on the outer peripheral wall of the cooling main pipe 322, and the guide member is located above the collection flow groove 315. This allows the liquid on the outer peripheral wall of the cooling main pipe 322 to fall more effectively into the collection flow groove 315, so that the liquid can quickly gather together and flow into the drainage channel 2131, thereby achieving rapid liquid collection. Further, the guide member protrudes from the outer peripheral wall of the cooling main pipe 322. Further details can be found in the following description. Figure 3 and Figure 7In order to improve the recovery rate of volatile oily gases in exhaust gas, in some other embodiments, the vertical bend 213 is provided with a diversion channel 2131. The diversion channel 2131 is used to receive and divert the liquid from the contact part 324, so that the diversion channel 2131 can quickly divert the liquid from the exhaust gas cold zone collector 310 to the filter plate 410, so as to avoid the phenomenon of liquid splashing and loss, thereby improving the recovery rate of volatile oily gases in exhaust gas.

[0068] Furthermore, please refer to Figure 3 and Figure 7 In some other embodiments, the drainage channel 2131 is located below the contact portion 324, so that the liquid coming out of the contact portion 324 of the exhaust gas cold zone collector 310 can fall well into the drainage channel 2131, so that the drainage channel 2131 can collect the liquid and introduce it into the filter plate 410.

[0069] Furthermore, in some other embodiments, please refer to Figure 3 and Figure 8 The drainage channel 2131 at least partially protrudes into the extraction tank 220 so that it can better guide the liquid into the filter plate 410. Furthermore, in some other embodiments, a liquid-blocking shield 2132 is provided at one end of the drainage channel 2131 near the filter plate 410. It is understood that by providing the liquid-blocking shield 2132 on the drainage channel 2131, the shield 2132 can effectively prevent liquid splashing. Furthermore, the liquid-blocking shield 2132 has a funnel-shaped cross-section. It is understood that because the funnel-shaped shield 2132 has a larger blocking area, it can more effectively improve the liquid blocking effect, further improving the liquid recovery rate.

[0070] In some other embodiments, please refer to Figure 8 The extraction tank 220 also includes a sealing cap 222. The extraction tank 220 has a drain port 223, and the sealing cap 222 is movably disposed within the drain port 223. It can be understood that by providing a drain port 223 on the extraction tank 220, and having the sealing cap 222 movably disposed within the drain port 223, the extraction tank 220 is ensured to be in a closed state during normal operation, thus better collecting volatile oily gases. Simultaneously, the added drain port 223 facilitates the user's quick removal of the suction component 420, enabling rapid recycling of the suction component 420. The suction component 420 can then be recycled as needed. For example, the suction component 420 can be placed in a heating and recovery device to collect impurity-free volatile oily gases, meeting the requirements for regeneration and recycling.

[0071] In some other embodiments, the exhaust gas extraction assembly is a blower to facilitate the flow of exhaust gas within the collection pipe 210 and the extraction tank 220, ensuring that the exhaust gas can enter the cavity 2121b from the inlet end 2111 of the collection section 2121 and the branch pipe 211, and then flow into the extraction tank 220 from the cavity 2121b. In some other embodiments, the blower rotates at a speed of 1000 r / h to 1200 r / h, and the diameter of the collection pipe 210 is 90 cm to 150 cm. It is understandable that by setting the speed of the exhaust fan to 1000r / h~1200r / h and the diameter of the collection pipe 210 to 90cm~150cm, the flow of exhaust gas in the cavity 2121b is ensured to be moderate, so that the exhaust gas can better and more fully contact the cooling pipe 320, thereby ensuring that more exhaust gas can be better cooled by the cooling pipe 320, thus improving the recovery of volatile oily gases in the exhaust gas.

[0072] In some other embodiments, please refer to Figure 8 The suction element 420 includes multiple absorbent balls to achieve rapid absorption of liquid, thereby enabling rapid collection of liquid. At the same time, multiple absorbent balls are used so that they can effectively absorb the liquid flowing down from the filter plate 410.

[0073] This application also provides a transfer printing device that employs the waste gas cold zone collection device 10 for textile transfer printing as described in any of the preceding claims. It is understood that by adding the waste gas cold zone collection device 10 for textile transfer printing to the transfer printing device, the waste gas in the textile transfer printing process can be collected. This not only improves the recovery rate of volatile oily gases but also enhances the waste gas collection effect, effectively preventing waste gas pollution of the air in the transfer printing workshop and thus ensuring the air quality of the transfer printing workshop.

[0074] Please see Figure 1 and Figure 3 In some other embodiments, the transfer equipment is provided with a worktable 600 for holding the textile fabric, thereby ensuring that the textile fabric can operate normally on the worktable 600. Further, the worktable 600 is disposed on the support 100, and the collection pipe 210 is located above the worktable 600, such that the opening 2121a of the collection section 2121 of the collection pipe 210 faces the transfer worktable 600 of the transfer equipment. This allows the opening 2121a to effectively collect the exhaust gas from the transfer worktable 600, so that the exhaust gas can better enter the outer peripheral wall of the cooling pipe 322.

[0075] Compared with the prior art, the present invention has at least the following advantages:

[0076] The aforementioned waste gas cooling zone collection device 10 for textile transfer printing, with the collection pipe 210 mounted on the support 100 for fixation, and the collection pipe 210 having a collection section 2121 forming a connected opening 2121a and a cavity 2121b, and the extraction tank 220 having an extraction port connected to the waste gas extraction assembly, allows the waste gas generated during textile transfer printing to be extracted from the opening 2121a into the cavity 2121b when the waste gas extraction assembly is operating normally. The cooling main pipe 322 is horizontally positioned within the cavity 2121b, allowing it to cover a large area within the cavity 2121b, thus maximizing the contact area between the waste gas entering the cavity 2121b and the cooling main pipe 322. When the coolant enters through the inlet pipe 321 and flows out through the outlet pipe 323, the volatile oily gases contained in the waste gas are removed. When the liquid comes into contact with the cooling main pipe 322, it is rapidly cooled into a liquid and adheres to the outer wall of the cooling main pipe 322. Since the waste gas cold zone collection component 310 is located inside the cavity 2121b and below the cooling pipe 320, the liquid adhering to the outer wall of the cooling main pipe 322 accumulates to a certain weight and falls onto the waste gas cold zone collection component 310. When the liquid in the waste gas cold zone collection component 310 accumulates to a certain amount, under the action of gravity, the liquid flows from the waste gas cold zone collection component 310 to the filter plate 410 in the extraction tank 220, is filtered by the filter plate 410, flows into the suction component 420, and is finally absorbed by the suction component 420. This achieves the recovery of volatile oily gases in the waste gas, not only improving the recovery rate of volatile oily gases but also providing good waste gas collection, effectively preventing waste gas pollution of the air in the transfer printing workshop, thereby ensuring the air quality of the transfer printing workshop. Furthermore, it can also obtain volatile oily liquids with high purity.

[0077] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
