Description

Technical Field

[0001] This application relates to the field of spinning technology, specifically to a waste gas discharge structure for a spinning box. Background Technology

[0002] Spinning, also known as chemical fiber forming, is an important process in the manufacture of chemical fibers. This process involves turning certain polymer compounds into colloidal solutions or melting them into melts, which are then extruded through the fine holes of a spinneret to form chemical fibers.

[0003] However, a large amount of waste gas is generated during the chemical fiber spinning process. This waste gas mainly comes from the heating, melting, spinning, stretching and post-processing of chemical fiber raw materials. The use of spinning oil is also one of the main causes of waste gas generation. Spinning oil can reduce friction and electrostatic effects during processing, making the fibers soft, smooth, elastic and cohesive, but it also leads to the emission of a large amount of oil fumes containing organic matter.

[0004] For example, patent CN220530708U discloses a polyester spinning waste gas recovery device. This patent not only cools the waste gas but also stirs the coolant by setting up waste gas cooling components that can be used for stirring in the primary cooler and final cooler, so that the coolant can absorb heat evenly and effectively improve the cooling effect.

[0005] When recovering waste heat from the waste gas generated during the spinning process, the waste gas may contain a variety of components, including gases generated by the volatilization of polymer melt, unreacted raw materials, additives, and possible fiber fragments. These components may form residues or pollutant particles in the waste gas. The residues and pollutant particles deposit in the heat exchange mechanism and form a thermal resistance layer, which hinders the transfer of heat from the waste gas to the cooling medium, thereby reducing the heat exchange efficiency.

[0006] Therefore, it is necessary to provide a waste gas discharge structure for the spinning box to solve the above problems.

[0007] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0040] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0042] like Figure 1-Figure 2 As shown, this application provides a waste gas discharge structure for a spinning box, including a spinning box 1. The spinning box 1 is installed in the factory to accommodate spinning raw materials and convert them into fibers through a specific process. Inlet ports 4 are fixedly provided on both sides of the spinning box 1 to introduce the spinning raw materials into the spinning box 1 for subsequent processing.

[0043] Furthermore, a heating chamber 8 is fixedly installed at the lower end of the spinning box 1. The heating chamber 8 can heat the spinning raw material through both oil heating and electric heating. At the same time, the heating chamber 8 is connected to the feed port 4 so that the spinning raw material can be introduced into the heating chamber 8 through the feed port 4 for heating treatment. Furthermore, a spinneret assembly 5 is installed at the lower end of the heating chamber 8 inside the spinning box 1. The spinneret assembly 5 has multiple sets of small holes so as to squeeze the heated spinning raw material into fine filaments and discharge them.

[0044] When the spinning operation begins, the spinning raw material is first introduced into the spinning box 1 through the feed port 4. After the spinning raw material enters the heating chamber 8 inside the spinning box 1, the spinning raw material can be heated by oil heating and electric heating.

[0045] When the raw material for spinning is heated to the required temperature, it is extruded through the small holes on the spinneret assembly 5 to form fine filaments;

[0046] like Figure 3-Figure 5 As shown, a certain amount of waste gas is generated during the spinning process. In order to treat the waste gas discharged from the spinning box 1, multiple sets of exhaust pipes 6 are fixedly installed on both sides of the heating chamber 8 inside the spinning box 1. The exhaust pipes 6 are arranged in sequence on both sides of the heating chamber 8 and are connected to the interior of the heating chamber 8 so that the waste gas inside the heating chamber 8 can be discharged. At the same time, an exhaust main pipe 7 is fixedly installed at the output end of the exhaust pipe 6. The exhaust main pipe 7 is used to collect the waste gas discharged from the exhaust pipe 6 so that it can be centrally treated in the later stage. At the same time, a heat exchange mechanism 2 is installed at one end of the exhaust main pipe 7 so that heat exchange is performed during the waste gas discharge process, thereby reducing the temperature of the waste gas and recovering some heat energy.

[0047] The heat exchange mechanism 2 includes a pipe 20 fixedly installed at one end of the exhaust pipe 7, and a heat exchange chamber 21 fixedly installed at the other end of the pipe 20. A heat exchange assembly is fixedly installed inside the heat exchange chamber 21. The heat exchange assembly includes multiple sets of heat exchange tubes 22. The heat exchange tubes 22 are arranged in a U-shape inside the heat exchange chamber 21 so that heat can be transferred through the tube wall to cool the exhaust gas or preheat other fluids.

[0048] Meanwhile, the input end and output end of the heat exchange tube 22 pass through the heat exchange chamber 21 and extend to the outside, and the inlet pipe 23 and the outlet pipe 24 are fixedly provided at the input end and the output end. The inlet pipe 23 and the outlet pipe 24 are used to introduce the medium to be heated into the heat exchange tube 22 and discharge it out of the heat exchange tube 22, thereby forming a heat exchange channel.

[0049] Furthermore, an exhaust fan 3 is fixedly installed at the output end of the heat exchange chamber 21. The exhaust fan 3 is used to provide power to extract the waste gas in the spinning box 1 so that the waste gas can be treated by the heat exchange mechanism 2 and finally discharged.

[0050] like Figures 4-8 As shown, in order to prevent the residues and pollutant particles in the exhaust gas from depositing in the heat exchange mechanism 2, thereby forming a thermal resistance layer that hinders the transfer of heat from the exhaust gas to the cooling medium and thus reduces the heat exchange efficiency, a filter assembly 25 is provided inside the heat exchange chamber 21 at the front end of the heat exchange assembly.

[0051] The filter assembly 25 includes a through hole on one side of the heat exchange chamber 21, and mounting plates 253 are fixedly provided on both sides of the heat exchange chamber 21. Mounting seats 255 are fixedly provided on the mounting plates 253, and rotating rollers 256 are rotatably provided between the mounting seats 255. A rotating ring 254 is fixedly provided on one side of one set of mounting plates 253. One end of the rotating ring 254 is fixedly connected to one end of the rotating roller 256 so that the rotating roller 256 can be driven to rotate between the mounting seats 255.

[0052] It should be noted that the rotating roller 256 is placed inside the heat exchange chamber 21, and both ends of the rotating roller 256 pass through the heat exchange chamber 21 and are rotatably disposed between the mounting bases 255.

[0053] Furthermore, an installation groove 258 is provided on one side of the rotating roller 256, and a filter screen 257 is provided on the installation groove 258. A platform is fixedly provided in the heat exchange chamber 21 at the position of the rotating roller 256. This platform is used to provide support for the filter screen 257, thereby preventing it from falling off.

[0054] In order to facilitate quick replacement of filter 257, a spring 261 is fixedly installed at one end inside the mounting slot 258. A locking block 260 is fixedly installed at one end of the spring 261, and locking slots 259 are provided on both sides of filter 257. The size of the locking block 260 is adapted to the size of the locking block 260. At the same time, a lever 262 is fixedly installed at the other end of the locking block 260 to facilitate easy disassembly of filter 257.

[0055] When the filter screen 257 needs to be installed, the spring 261 can be compressed by pulling the lever 262. At this time, the filter screen 257 is placed in the mounting slot 258. After aligning the slot 259 with the locking block 260, the locking block 260 is inserted into the slot 259 to install the filter screen 257. When it needs to be disassembled, simply pull the lever 262 to make the locking block 260 leave the slot 259 to complete the disassembly of the filter screen 257 for subsequent cleaning.

[0056] In order to quickly replace the used filter 257, a cover 263 is hinged to both sides of the through hole on the heat exchange chamber 21, and a sealing gasket 250 is fixedly installed at the connection between the cover 263 and the heat exchange chamber 21 to prevent exhaust gas leakage. At the same time, a handle 252 is fixedly installed at one end of the cover 263 so that the operator can pull the cover 263 to open the through hole on the heat exchange chamber 21, thereby facilitating the subsequent replacement operation.

[0057] When replacement is needed, the cover 263 can be pulled by the handle 252 to open the through hole, and then the rotating ring 254 can be rotated to drive the rotating roller 256 to rotate until the filter screen 257 is rotated to the outside of the heat exchange chamber 21. At this time, the lever 262 can be pulled to make the locking block 260 disengage from the locking slot 259 to complete the removal of the filter screen 257. After the unused filter screen 257 is installed, the rotating ring 254 can be rotated in the opposite direction to drive the rotating roller 256 to rotate in the opposite direction until the filter screen 257 is placed on the platform inside the heat exchange chamber 21. Finally, the cover 263 can be pulled to cover the through hole, thereby completing the replacement of the filter screen 257.

[0058] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
