[0002] Fabric dyeing and finishing refers to a series of chemical and physical processing steps applied to textile fabrics to improve their appearance, feel, performance, and function, making them meet specific usage requirements and market demands. It is a crucial link in the textile industry chain, directly impacting the quality and value of the final textile products.

[0003] The heat exchange device used in dyeing and finishing equipment introduces the hot waste gas generated by the dyeing and finishing equipment into the heat exchanger, which lowers the temperature and transfers the heat it carries to other media (such as fresh air, cold water, etc.), thus realizing heat recovery and utilization.

[0004] In order to prevent impurities in the hot exhaust gas from affecting the heat exchange process, existing tubular heat exchange devices used in dyeing and finishing equipment have a filter structure installed on the gas pipe. The filter structure is usually large and requires a lot of space, which affects the compactness of the layout of the dyeing and finishing equipment. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a heat exchange device for dyeing and finishing equipment, so as to solve the problem that in the process of using existing tubular heat exchange devices for dyeing and finishing equipment, in order to prevent impurities in the hot exhaust gas from affecting the heat exchange operation, a filter structure is set on the gas pipe. The filter structure is usually large in size, requires a lot of space, and affects the compactness of the layout of the dyeing and finishing equipment.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a heat exchange device for dyeing and finishing equipment, the structure of which includes a horizontally arranged heat exchange tube body, a water outlet, a water inlet, and a hot exhaust gas outlet; the water outlet is connected to one end of the heat exchange tube body; the water inlet is connected to the other end of the heat exchange tube body; and two hot exhaust gas outlets are provided and are spaced apart on the upper end face of the heat exchange tube body. An automatic opening and closing filter assembly is provided inside the hot exhaust gas interface opening. The automatic opening and closing filter assembly includes a cover plate that closes the hot exhaust gas interface opening and a drive seat located horizontally inside the bottom of the hot exhaust gas interface. The drive seat has several airflow channels arranged in a ring around its edge. An assembly groove is provided at the center of the top surface of the drive seat. A linear actuator is vertically fixed on the assembly groove. The output end of the linear actuator faces upward and is connected to the center of the bottom surface of the cover plate. The upper opening of the airflow channel is connected to the filter structure in a detachable manner. The outer side of the cover plate has several guide holes that extend to the bottom surface of the cover plate.

[0007] Furthermore, in order to perform heat exchange, a partition is provided in both the left and right parts of the heat exchange tube body, and several water pipes are connected between the two partitions, forming a heat exchange chamber that communicates with the hot exhaust gas interface.

[0008] Furthermore, in order to carry out the input and output of gas, one of the hot exhaust gas interfaces is a hot exhaust gas input interface, and the other hot exhaust gas interface is an exhaust gas output interface.

[0009] Furthermore, in order to ensure the normal operation of the linear actuator, the hot exhaust gas interface is externally connected to a high-temperature resistant conductive wire that supplies power to the linear actuator.

[0010] Furthermore, a protective cover is provided on the outside of the assembly slot to cover the linear actuator, so as to prevent hot exhaust gas from contacting the linear actuator. The top surface of the protective cover is sealed and connected through the output end of the linear actuator.

[0011] Furthermore, for ease of assembly and disassembly, the filter structure includes a filter screen cylinder with its opening facing downwards and an externally threaded connecting ring connected to the opening of the filter screen cylinder. The externally threaded connecting ring is threadedly connected to the upper opening of the airflow channel.

[0012] Furthermore, to improve the robustness of the connection, the drive seat has a disc-shaped structure and is connected to the hot exhaust gas interface by integral molding or welding.

[0013] The beneficial effects of this utility model are: in the tubular heat exchange device used in dyeing and finishing equipment, an automatic opening and closing filter component is adopted in the hot exhaust gas interface. It can be automatically opened and closed by a linear drive and a cover plate. At the same time, several detachable filter structures are set on the drive base, which improves the filtration efficiency, facilitates subsequent maintenance and repair work, reduces the space occupation, and prevents it from affecting the compact layout of the dyeing and finishing equipment.

[0017] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 This utility model provides a technical solution for a heat exchange device for dyeing and finishing equipment: its structure includes a horizontally arranged heat exchange tube 1, a water outlet 2, a water inlet 3, and a hot exhaust gas outlet 4; the water outlet 2 is connected to one end of the heat exchange tube 1; the water inlet 3 is connected to the other end of the heat exchange tube 1; there are two hot exhaust gas outlets 4, which are spaced apart on the upper surface of the heat exchange tube 1; like Figure 3 , 4 As shown, an automatic opening and closing filter assembly is provided inside the opening of the hot exhaust gas interface 4. The automatic opening and closing filter assembly includes a cover plate 41 that closes the opening of the hot exhaust gas interface 4 and a drive seat 42 located horizontally inside the bottom of the hot exhaust gas interface 4. The drive seat 42 has a plurality of airflow channels 43 arranged in a ring around its edge. The drive seat 42 has an assembly groove 44 at the center of its top surface. A linear actuator 45 is vertically fixed on the assembly groove 44. The output end of the linear actuator 45 faces upward and is connected to the center of the bottom surface of the cover plate 41. The upper opening of the airflow channel 43 is a filter structure that can be detachably connected. like Figure 5 As shown, the cover plate 41 has several guide holes 411 extending to the bottom surface of the cover plate 41 on its outer side. The cover plate 41 is specifically a metal sealing cover plate, and the outer ring of the metal sealing cover plate is provided with a high-temperature resistant spring sealing ring that contacts the inner wall of the hot exhaust gas interface 4.

[0018] It also includes a console for peripherals, which is radio-connected to the linear driver 45.

[0019] In order to perform heat exchange, a partition 21 is provided in both the left and right parts of the heat exchange tube body 1. Several water pipes 22 are connected between the two partitions 21, and a heat exchange chamber 23 is formed between the water pipes 22, which communicates with the hot exhaust gas interface 4.

[0020] In order to carry out the input and output of gas, one of the hot exhaust gas interfaces 4 is a hot exhaust gas input interface, and the other hot exhaust gas interface 4 is an exhaust gas output interface.

[0021] In order for the linear actuator 45 to operate normally, the hot exhaust gas interface 4 is externally connected to a high-temperature resistant conductive wire that supplies power to the linear actuator 45.

[0022] The assembly slot 44 is provided with a protective cover that covers the linear actuator 45 to prevent hot exhaust gas from contacting the linear actuator 45. The top surface of the protective cover is sealed and connected through the output end of the linear actuator 45.

[0024] To improve structural stability, the drive seat 42 is in the shape of a disc and is integrally formed with the hot exhaust gas interface 4.

[0025] Principle: When the dyeing and finishing equipment is working, the hot exhaust gas generated is introduced into the hot exhaust gas interface 4 through the air pipe, and cold water is input through the water inlet interface 3. The automatic opening and closing filter component in the hot exhaust gas interface 4 will automatically open. The cover plate 41 is driven to move upward by the linear actuator 45, releasing the opening of the hot exhaust gas interface 4. At the same time, the guide hole 411 is exposed.
