Description

Technical Field

[0001] This application relates to the field of textile equipment technology, and in particular to a spinning box with a self-cleaning function. Background Technology

[0002] As a core piece of equipment in the chemical fiber manufacturing process, the spinning box's main function is to heat and maintain the temperature of polymer melts or solutions, and then evenly distribute them to various spinning sections. However, in practical applications, the internal environment of the spinning box is complex and diverse. Especially when operating under high-temperature conditions, various by-products are easily deposited, such as coking products and polymer degradation residues. These problems have gradually become significant bottlenecks restricting the improvement of production efficiency.

[0003] Most existing cleaning methods can only be carried out when production is stopped, which means that each cleaning process will inevitably cause the production line to stop, thus seriously affecting the overall operational rhythm.

[0004] To effectively clean the accumulated dirt inside the spinning box without interrupting production, Chinese Patent No. CN219490247U discloses a spinning box for nylon fiber production that facilitates internal cleaning. The box includes: a spinning box body with an open bottom; a base detachably mounted on the bottom of the spinning box; a cleaning frame with multiple cleaning brushes fixedly mounted on its front, rear, left, and right sides, all of which movably contact the interior of the spinning box body; and insertion holes on both sides of the top of the cleaning frame; and a drive assembly including a worm gear, two lead screws, two cross plates, and two worm wheels. The two lead screws are rotatably connected to the top sides of the spinning box body, and the two worm wheels are fixedly mounted on the outer sides of their respective lead screws.

[0005] When faced with coking deposits, the aforementioned spinning box suffers from significant problems due to the strong adhesiveness of these deposits. Simply scraping with a cleaning brush is insufficient to completely remove them. During the scraping process, the coking deposits not only remain on the inner wall of the spinning box but also adhere extensively to the cleaning brush. Over time, a thick layer of coking deposits accumulates on both the cleaning brush and the inner wall of the spinning box. Even after cleaning, the cleanliness of the spinning box's interior remains low and fails to meet the stringent cleanliness requirements of spinning production. Utility Model Content

[0006] In order to improve the cleaning efficiency of automatic cleaning of accumulated dirt inside the spinning box, this application provides a spinning box with self-cleaning function.

[0007] The spinning box with self-cleaning function provided in this application adopts the following technical solution:

[0008] A self-cleaning spinning box includes a spinning box body. Multiple vertically arranged guide posts are distributed within the spinning box body. A cleaning frame is slidably mounted on each guide post. Multiple sets of elastic scraper assemblies are arranged around the outer wall of the cleaning frame. Each set of elastic scraper assemblies is tightly fitted against the inner wall of the spinning box body. An electric drive assembly for raising and lowering the cleaning frame is located within the spinning box body. A storage tank for storing cleaning fluid is disposed on one side of the spinning box body. A spraying device is detachably mounted on the bottom of the cleaning frame. The storage tank supplies cleaning fluid to the spraying device via a supply pipe and a booster pump. The spraying device has several ejection holes for directional spraying, with the spray direction of the ejection holes pointing towards the inner wall surface of the spinning box body.

[0009] By employing the above technical solution, the spraying device precisely sprays cleaning fluid onto the target area, effectively softening and flushing away stubborn residues. Then, the cleaning frame, driven by an electric drive assembly, moves up and down, causing multiple sets of elastic scraper components to perform a comprehensive, physical scraping of the inner wall. This combination method has a stronger ability to remove coking deposits that are difficult to handle with traditional methods. It not only improves the effectiveness of a single cleaning operation but also extends the time the equipment remains in good condition, thereby indirectly improving the stability and efficiency of continuous production.

[0010] Optionally, the electric drive assembly includes a vertically arranged drive screw, a driven bevel gear sleeved on the top of the drive screw, a servo motor arranged on the outer wall of the spinning box body, and an active bevel gear sleeved on the output end of the servo motor. The drive screw rotates through the cleaning frame via a thread, the output shaft of the servo motor rotates through the side wall of the spinning box body, and the active bevel gear is located inside the spinning box body and meshes with the driven bevel gear.

[0011] By adopting the above technical solution, the servo motor drives the active bevel gear to rotate, and the active bevel gear meshes with the driven bevel gear to drive the drive screw to rotate. Since the drive screw and the cleaning frame are connected by a thread, the cleaning frame can move up and down along the guide post when the drive screw rotates. This design achieves automated lifting control of the cleaning frame, allowing the elastic scraper assembly to fully cover the inner wall of the spinning box for scraping operations, significantly improving cleaning efficiency and coverage. Simultaneously, the precise adjustment of the cleaning frame position using the servo motor improves the controllability and stability of the cleaning process, reducing the inconvenience and errors caused by manual intervention.

[0012] Optionally, the inner bottom of the spinning box body is shaped like a bucket, and a drain outlet is provided at the lowest point of the bottom. A drain pipe is connected to the drain outlet, and a suction pump is provided on the drain pipe.

[0013] By adopting the above technical solution, the inner bottom of the spinning box body is designed as a bucket-shaped structure, which can effectively guide the accumulated dirt and waste liquid to the lowest point at the bottom. Combined with the design of the drain port and drain pipe, the automatic discharge is achieved by using a suction pump, which improves the efficiency of waste discharge during the cleaning process and avoids the problem of residue accumulation in traditional cleaning methods, thereby improving the overall cleaning effect of the spinning box.

[0014] Optionally, the top of the storage tank is sealed with a tank cover, and a filter device is installed inside. The filter device divides the inside of the storage tank into a waste liquid chamber and a filtrate chamber from top to bottom. The outlet end of the drain pipe is connected to the tank cover and communicates with the waste liquid chamber. The inlet end of the inlet pipe is connected to the bottom side wall of the storage tank and communicates with the filtrate chamber.

[0015] By adopting the above technical solution, the filtration device divides the storage tank into a sludge chamber and a filtrate chamber, so that the liquid containing impurities discharged from the drain pipe first enters the sludge chamber. After being processed by the filtration device, the clean cleaning liquid enters the filtrate chamber and is then supplied to the spraying device through the inlet pipe. This greatly improves the reuse rate of the cleaning liquid, reduces resource consumption, and also improves the long-term stability and reliability of the self-cleaning system.

[0016] Optionally, the inner ring of the storage tank is provided with an overlapping ring, and the filtration device includes a filter screen frame overlapping on the overlapping ring and a screen inserted into the filter screen frame. The inner sidewall of the filter screen frame is provided with overlapping plates opposite each other, and the bottom wall of the frame of the screen overlaps with the two overlapping plates. The mesh diameter of the filter screen frame is smaller than the mesh diameter of the screen, and a space for temporary storage of fine impurities is formed between the screen and the filter screen frame.

[0017] By adopting the above technical solution, the overlapping ring inside the storage tank provides a stable support structure for the filtration device, allowing the filter frame to be securely placed inside the storage tank. The filter frame first intercepts larger impurities, while the screen inserted inside the filter frame further filters finer particles. Because the mesh diameter of the screen is smaller than that of the filter frame, the two work together to form a two-stage filtration mechanism. This not only improves filtration efficiency but also utilizes the space between the screen and the filter frame to temporarily store the filtered fine impurities, reducing the possibility of them re-mixing into the cleaning solution. This ensures the purity of the cleaning solution, extends its effective service life, reduces the need for frequent cleaning solution changes, and lowers maintenance costs.

[0018] Optionally, a viewing window is provided on the side wall of the storage tank. The viewing window is arranged vertically to facilitate observation of the liquid level of the cleaning fluid and the filtering of impurities on the filter device.

[0019] By adopting the above technical solution, the viewing window allows for a clear and intuitive display of the cleaning fluid level changes, ensuring timely replenishment of the fluid and preventing the spraying device from operating abnormally due to low fluid levels. At the same time, it also allows for a clear observation of the impurity buildup on the filter, reminding users to clean or replace the filter structure in a timely manner, thereby ensuring the efficient and stable operation of the entire self-cleaning system.

[0020] Optionally, an insertion groove is provided on the outer side wall of the cleaning frame. One end of the insertion groove extends to the side wall of the cleaning frame, and the cross-section of the insertion groove is wedge-shaped. One insertion groove is provided along the outer peripheral side wall of the cleaning frame. An insertion part is slidably inserted into each insertion groove. The elastic scraper assembly corresponds to the insertion part one by one, and the insertion part is located on the end of the elastic scraper assembly.

[0021] By adopting the above technical solution, when the elastic scraper of the cleaning frame wears or fails due to long-term use, the plug-in part and its corresponding elastic scraper assembly can be easily removed by sliding insertion, without complicated tools or disassembly steps. This design significantly improves the maintenance efficiency of the equipment, reduces downtime caused by component damage, and improves the quality and continuity of cleaning operations inside the spinning box.

[0022] Optionally, the elastic scraper assembly includes a base frame made of a flexible metal sheet and a rubber layer covering its outer surface.

[0023] By adopting the above technical solution, the basic frame made of flexible metal sheets ensures that the elastic scraper assembly has a certain degree of flexibility and support, allowing it to better adapt to the shape changes of the inner wall of the spinning box during cleaning, while avoiding equipment damage caused by excessive rigidity. The outer rubber coating further enhances the friction and sealing between the scraper and the inner wall, helping to improve the removal ability of stubborn dirt, especially when dealing with sticky residues such as coke, thereby significantly improving cleaning efficiency and extending the service life of the equipment.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The spraying device precisely sprays cleaning fluid onto the target area, effectively softening and flushing away stubborn residues. Then, the cleaning frame, driven by an electric drive assembly, moves up and down, causing multiple sets of elastic scraper components to perform a comprehensive physical scraping of the inner wall. This combination method has a stronger ability to remove coking deposits that are difficult to handle with traditional methods. It not only improves the effectiveness of a single cleaning operation but also extends the time the equipment remains in good condition, thereby indirectly improving the stability and efficiency of continuous production.

[0026] 2. A servo motor drives the active bevel gear to rotate, which meshes with the driven bevel gear to drive the drive screw. Since the drive screw and the cleaning frame are connected by a thread, the cleaning frame can move up and down along the guide post when the drive screw rotates. This design achieves automated lifting control of the cleaning frame, allowing the elastic scraper assembly to fully cover the inner wall of the spinning box for scraping operations, significantly improving cleaning efficiency and coverage. Simultaneously, the precise adjustment of the cleaning frame position using a servo motor improves the controllability and stability of the cleaning process, reducing the inconvenience and errors caused by manual intervention.

[0027] 3. The inner bottom of the spinning box is designed as a funnel-shaped structure, which can effectively guide the accumulated dirt and waste liquid to the lowest point. Combined with the design of the drain port and drain pipe, the automatic discharge is achieved by using a suction pump, which improves the efficiency of waste discharge during the cleaning process and avoids the problem of residue accumulation in traditional cleaning methods, thereby improving the overall cleaning effect of the spinning box.

[0035] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0036] This application discloses a spinning box with a self-cleaning function.

[0037] Reference Figure 1 , Figure 2 and Figure 3 A self-cleaning spinning box includes a spinning box body 1, a cleaning frame 2, and an electric drive assembly 3 inside the spinning box body 1. The bottom of the spinning box body 1 is funnel-shaped, and a drain port 11 is opened at the lowest point of the bottom. A drain pipe 111 is installed at the drain port 11, and a suction pump 112 is connected in series on the drain pipe 111. A set of elastic scraper assemblies 4 are detachably installed on the four outer walls of the cleaning frame 2, and each set of elastic scraper assemblies 4 is tightly fitted to the corresponding inner wall of the spinning box body 1. A storage tank 5 for storing cleaning fluid is arranged on one side of the spinning box body 1. A spraying device 6 is detachably installed at the bottom of the cleaning frame 2. The spraying device 6 has several emission holes 61 connected to the cleaning fluid. The spraying direction of the several emission holes 61 is directed towards the inner wall surface of the spinning box body 1. The storage tank 5 supplies cleaning fluid to the spraying device 6 through a supply pipe 51 and a booster pump 52.

[0038] Reference Figure 1 , Figure 2 and Figure 3When the spinning box needs internal cleaning, the liquid storage tank 5 delivers cleaning liquid to the spraying device 6 through the liquid supply pipe 51 and the booster pump 52. The spraying device 6 then accurately sprays the cleaning liquid to the target area through the emission hole 61. Subsequently, the cleaning frame 2 moves up and down under the action of the electric drive component 3, driving multiple sets of elastic scraper components 4 to perform a comprehensive physical scraping of the inner wall. The scraped-off dirt and waste liquid gather at the lowest point at the bottom and are sucked out of the sewage pipe 111 by the suction pump 112 and removed from the spinning box body 1.

[0039] Reference Figure 2 and Figure 3 In this embodiment, the liquid supply pipe 51 is a telescopic multi-section pipe that can freely extend and retract within the lifting stroke of the spraying device 6. In order to avoid the elastic scraper assembly 4 interfering with the stretching of the liquid supply pipe 51 during the lifting process, a groove 12 is provided on the inner side wall of the spinning box body 1 to allow the liquid supply pipe 51 to move.

[0040] Reference Figure 3 To reduce the possibility of clogging of the emission holes 61, each emission hole 61 is connected to a nozzle 611 by a threaded rotation, and the spray direction of the nozzles 611 is directed towards the inner wall surface of the spinning box body 1.

[0041] Reference Figure 3 and Figure 4 An insertion groove 21 is provided on the outer side wall of the cleaning frame 2. One end of the insertion groove 21 extends to the side wall of the cleaning frame 2, and the cross-section of the insertion groove 21 is wedge-shaped. There is one insertion groove 21 on each outer peripheral side wall of the cleaning frame 2. An insertion part 211 is slidably inserted into each insertion groove 21 in the horizontal direction. The elastic scraper assembly 4 corresponds to the insertion part 211 one by one, and the insertion part 211 is integrally formed on the end of the elastic scraper assembly 4. In this embodiment, the elastic scraper assembly 4 includes a basic frame 41 and a rubber layer 42. The basic frame 41 is made of a flexible metal sheet, and the rubber layer 42 covers its outer surface to ensure that the elastic scraper assembly 4 has a certain degree of flexibility and support, while also reducing the possibility of damage to the inner side wall of the spinning box body 1 due to excessive rigidity.

[0042] Reference Figure 1 , Figure 2 and Figure 3A vertical guide post 13 is fixedly installed at one of the three corners inside the spinning box body 1. The cleaning frame 2 is slidably sleeved on the three guide posts 13. The electric drive assembly 3 includes a drive screw 31, a driven bevel gear 32, a servo motor 33, and a driving bevel gear 34. The drive screw 31 is located at the remaining corner and is vertically rotatably installed inside the spinning box body 1. The drive screw 31 passes through the cleaning frame 2 through a threaded rotation. The driven bevel gear 32 is fixedly sleeved on the top end of the drive screw 31. The servo motor 33 is fixedly installed on the outer wall of the spinning box body 1. Its output shaft rotatably passes through the side wall of the spinning box body 1 and extends into the spinning box body 1. The driving bevel gear 34 is fixedly sleeved on the end of the output shaft of the servo motor 33 and meshes with the driven bevel gear 32.

[0043] Reference Figure 2 and Figure 4 The bottom wall of the cleaning frame 2 has two parallel mounting slots 22 on both sides. Each mounting slot 22 has a mounting strip 62 that is slidably inserted into it. The mounting strip 62 is integrally formed on the top of the spraying device 6. A limiting rod 7 is vertically inserted through the cleaning frame 2. The bottom end of the limiting rod 7 is hemispherical. The mounting strip 62 has a hole 621 that is inserted into the bottom end of the limiting rod 7. A fixing block 71 is fixedly installed on the top end of the limiting rod 7 extending out of the top wall of the cleaning frame 2. A spring 72 is sleeved on the limiting rod 7. The spring 72 abuts against the side wall of the cleaning frame 2 opposite to the fixing block 71. When the spring 72 is in its natural state, the bottom end of the limiting rod 7 passes through the mounting slot 22 and is inserted into the corresponding hole 621 on the mounting strip 62.

[0044] Reference Figure 1 and Figure 5 The top of the storage tank 5 is sealed with a tank cover 53, and the top of the tank cover 53 is connected to an injection pipe 531. The outlet end of the drain pipe 111 is also connected to the tank cover 53. A drain pipe 54 is connected to the bottom side wall of the storage tank 5, and a solenoid valve 541 is installed on the drain pipe 54. A viewing window 55 is installed on the side wall of the storage tank 5. The viewing window 55 is vertically arranged and sealed with transparent glass, allowing observation of the details inside the storage tank 5. A filter device 8 is installed inside the storage tank 5, which divides the interior of the storage tank 5 into a waste liquid chamber 56 and a filter liquid chamber 57 from top to bottom. The inlet end of the inlet pipe is connected to the bottom side wall of the storage tank 5 and is connected to the filter liquid chamber 57.

[0045] Reference Figure 5The storage tank 5 has an inner fixing ring with an overlapping ring 58. The filter device 8 includes a filter frame 81 and a screen 82. The filter frame 81 is inserted into the storage tank 5, and its bottom is attached to the overlapping ring 58. Handles 9 are provided on both sides of its top for easy lifting. An overlapping plate 811 is fixedly provided on the inner side wall of the filter frame 81. The bottom wall of the frame of the screen 82 is attached to the two overlapping plates 811. The mesh diameter of the filter frame 81 is smaller than that of the screen 82, and a space is formed between the screen 82 and the filter frame 81 to temporarily store fine impurities.

[0046] The implementation principle of a self-cleaning spinning box according to an embodiment of this application is as follows: when the spinning box needs internal cleaning, the storage tank 5 delivers cleaning liquid to the spraying device 6 through the supply pipe 51 and the booster pump 52, and the spraying device 6 precisely sprays the cleaning liquid to the target area through the nozzle 611.

[0047] Subsequently, after the servo motor 33 starts, it drives the active bevel gear 34 to rotate, which in turn causes the driven bevel gear 32 meshing with it to operate synchronously. This ultimately transforms into linear motion, pushing the cleaning frame 2 to rise or fall, thereby driving multiple sets of elastic scraper assemblies 4 to perform comprehensive physical scraping of the inner wall. The scraped-off dirt and waste liquid gather at the lowest point at the bottom and are drawn into the storage tank 5 from the drain pipe 111 by the suction pump 112. The liquid containing impurities discharged from the drain pipe 111 first enters the waste liquid chamber 56. After secondary filtration treatment by the screen 82 and the filter frame 81, the clean cleaning liquid enters the filtrate chamber 57 and is then supplied to the spraying device 6 for circulation through the inlet pipe until the cleaning liquid becomes ineffective. Finally, it is discharged from the drain pipe 54, and new cleaning liquid is injected from the injection pipe 531 for circulation.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
