Description

Technical Field

[0001] This invention specifically relates to a carbon fiber spinneret cleaning device. Background Technology

[0002] Carbon fiber spinnerets are key components in the carbon fiber production process. Their function is to extrude polyacrylonitrile (PAN) solution or melt, the precursor material for carbon fibers, through micropores to form fibers. These fibers then undergo a series of processing steps, including pre-oxidation and carbonization, to ultimately form carbon fibers.

[0003] During the extrusion of carbon fiber spinnerets to form fibers, some material may remain inside the micropores of the spinneret, causing blockage. To ensure the quality of the carbon fiber, the micropores inside the spinneret need to be cleaned periodically. There are various ways to clean the micropores inside the carbon fiber spinneret. Traditional high-temperature calcination cleaning and chemical cleaning methods can damage the spinneret after long-term use. Therefore, most existing technologies use water particle cleaning. Water particle cleaning uses room temperature tap water to convert it into a particle state to physically clean the spinneret, avoiding the high-temperature treatment process of traditional cleaning processes. The treated mold does not have problems such as deformation, cracks, or chemical damage.

[0004] In existing technologies, water particle cleaning is typically used to flow pressurized water through the micropores inside the carbon fiber spinneret. By increasing the water pressure, the deposits attached to the sidewalls of the feed and discharge ports can be effectively removed. However, because the spinneret's micropores have conical connecting holes that connect the feed and discharge ports, the water flow cannot clean the conical structure. Instead, the cleaned-off deposits accumulate at the conical area, leading to buildup over time and affecting the carbon fiber spinneret's output performance.

[0005] Chinese Patent No. 202110217188.5, entitled "A High-Efficiency Cleaning Method and Apparatus for Spinnerets of Dry-Jet Wet-Spinned Carbon Fiber Prototype," describes a system comprising: a cleaning tank, a cleaning agent circulation pipeline, an ultrasonic cleaning device, and a mold temperature controller. The cleaning tank is connected to the cleaning agent circulation pipeline; the inlet of the cleaning agent circulation pipeline is connected to the outlet of the cleaning tank; the outlet of the cleaning agent circulation pipeline is connected to the cleaning agent inlet at the top of the cleaning tank; one end of the cleaning agent circulation pipeline has several branches, each branch connected to a quick-connect fitting; some branches are connected to the cleaning tank, and some branches are located outside the cleaning tank; the ultrasonic cleaning device is connected to the cleaning tank; and the mold temperature controller is connected to the cleaning tank. The ultrasonic cleaning device is located at the bottom of the cleaning tank, and the quick-connect fitting is located at the top of the cleaning tank, connecting to the spinneret so that the spinneret is placed horizontally, with the spinneret facing the ultrasonic cleaning device. The cleaning agent is sulfoxide... A mixture of dimethylacetamide; during the rinsing process of the cleaning agent, the nitrogen gas in the cleaning agent is maintained at a slight positive pressure of 10-20 kPa; a filter is installed on the cleaning agent circulation pipeline; it also includes an overflow pipeline, one end of which is connected to the outlet of the filter and the other end is connected to the cleaning tank, and a second pipeline valve and an overflow valve are installed on the overflow pipeline; a third pipeline valve is installed at the outlet of the cleaning agent liquid on the cleaning agent circulation pipeline; a jacket is installed on the side wall of the cleaning tank, and the jacket is connected to the mold temperature controller through a pipeline; the cleaning agent in the cleaning tank is first introduced into the branch on the outside of the cleaning tank to perform the first pre-cleaning of the spinnerets on the branch on the outside of the cleaning tank. After the cleaning agent is sprayed out of the spinnerets, the spinnerets are moved to the quick connector inside the cleaning tank, so that the spinnerets and their components are connected to the quick connector, and then the cleaning agent begins to circulate to clean the spinnerets for the second time, further washing the residual slurry in the spinneret holes of the spinnerets.

[0006] As shown in the attached figure of patent 202110217188.5, this patent mainly uses a combination of chemical reagents and ultrasonic cleaning. First, chemical reagents are used for preliminary cleaning, and then ultrasonic cleaning is used for secondary cleaning. This patent can clean the spinneret, but chemical reagents are easy to corrode the spinneret. At the same time, the cleaning device of this patent can only clean one spinneret at a time, which is inefficient. Summary of the Invention

The pushing component pushes the spinnerets on the conveying section to enter the cleaning and drying section in sequence for cleaning or drying.

[0011] A return assembly is provided on one side of the cleaning and drying section of the conveying section. The return assembly pushes the cleaned or dried spinneret back into the conveying section.

[0012] In a preferred embodiment of the present invention, the conveying unit includes a conveying frame, a gear chain mechanism, a feeding plate, and a spinneret placement plate. The conveying frame is mounted on the ground via a support frame. The spinneret placement plate, used to hold the spinnerets, is placed on the feeding plate. The feeding plate is connected to the chain within the gear chain mechanism. The gear chain mechanism is mounted on the conveying frame. The spinneret placement plate, which holds the spinnerets, can move controllably under the action of the gear chain mechanism. The conveying unit facilitates the conveying of the spinnerets to the various components of the cleaning and drying unit, making the cleaning and drying of the spinnerets convenient and easy to use.

[0013] In a preferred embodiment of the present invention, the spinneret placement plate includes a discharge hole, a liquid guiding groove, and a sealing groove. The spinneret is placed in the discharge hole, which is connected to the liquid guiding groove. Liquid during the cleaning process is discharged through the liquid guiding groove.

The spinneret placement plate facilitates the fixing of the spinneret, makes cleaning the spinneret convenient, and is easy to use.

[0014] In a preferred embodiment of the present invention, the steam cleaning assembly includes a high-pressure steam generator, a steam hood, and an exhaust box. The high-pressure steam generator is connected to the steam hood, and the exhaust box is located below the steam hood. A pushing assembly pushes a spinneret placement plate containing a spinneret to the space between the steam hood and the exhaust box. The distance between the steam hood and the spinneret placement plate is controllably adjustable. The steam hood sprays high-pressure hot steam to perform preliminary cleaning on the spinneret. The steam cleaning assembly facilitates the spraying of high-pressure hot steam onto the spinneret, which is convenient for softening and discharging the PAN solution solidified in the micropores of the spinneret. The cleaning process is thorough and ensures effective cleaning.

[0015] In a preferred embodiment of the present invention, the vibration cleaning assembly includes an ultrasonic vibrator, a material support plate, and a vibrator support frame.

[0016] In a preferred embodiment of the present invention, the rinsing assembly includes a rinsing mechanism and a rinsing sealing mechanism. The rinsing mechanism is connected to the rinsing sealing mechanism. The rinsing mechanism includes a water inlet pipe, and the rinsing sealing mechanism includes a rinsing sealing cover. The water inlet pipe is connected to the rinsing sealing cover. The pushing assembly pushes the spinneret placement plate, on which the spinneret is placed, below the rinsing sealing cover. The distance between the rinsing sealing cover and the spinneret placement plate is controllably adjustable. The rinsing sealing cover sprays high-pressure liquid to clean the spinneret for the final cleaning. The rinsing assembly facilitates the cleaning of the PAN that has loosened after vibration on the surface of the spinneret, ensuring the cleaning effect of the spinneret.

[0017] In a preferred embodiment of the present invention, the drying assembly includes a draining tank and a hot air blower. The draining tank is located on the ground, and the hot air blower is connected to the draining tank. The pushing assembly pushes the spinneret placement plate containing the spinneret to the space between the draining tank and the hot air blower. The hot air blower dries the moisture inside the spinneret on the spinneret placement plate. This arrangement effectively prevents moisture retention inside the spinneret from causing corrosion and improves the service life of the spinneret.

[0018] In a preferred embodiment of the present invention, the material pushing assembly includes a material pushing cylinder and a cylinder mounting frame. The cylinder mounting frame is set on the ground, and the material pushing cylinder is set on the cylinder mounting frame. There are multiple material pushing cylinders, each corresponding to a component on the cleaning and drying section. The material pushing cylinder pushes the spinneret placement plate on the conveying section to the component on the cleaning and drying section. The material pushing assembly facilitates the transportation of the spinneret to be cleaned into the cleaning and drying section.

[0019] In a preferred embodiment of the present invention, the return assembly includes a return cylinder and a return pusher plate. There are multiple return cylinders, which are respectively installed at various components on the cleaning and drying section. The return pusher plate is connected to the return cylinder. The return cylinder drives the return pusher plate to push the cleaned or dried spinneret plate back onto the conveying section. The return assembly facilitates the return of the cleaned or dried spinneret plate to the conveying section and is easy to use.

[0020] To address the second technical problem, this invention also proposes a cleaning method for a carbon fiber spinneret cleaning device; specifically, it includes the following steps:

[0021] S1: Removal: Remove the spinneret from the spinneret;

[0022] S2: Feeding: Place the spinneret onto the feeding hole on the spinneret placement plate with the feed inlet on the spinneret facing down, and then place the spinneret placement plate onto the feeding plate on the conveyor section.

[0023] S3: Start: Start the equipment. The gear chain mechanism on the conveyor section drives the spinneret placement plate to move forward.

[0024] S4: Steam Cleaning: When the feeding plate moves close to the steam cleaning component, the gear chain mechanism stops moving. The pusher component at the corresponding steam cleaning component pushes the spinneret placement plate to the steam cleaning component. The steam hood inside the steam cleaning component descends, sealing the spinneret placement plate. The steam nozzles spray high-pressure hot steam to clean the spinneret. After cleaning, the return component at the steam cleaning component pushes the steam-cleaned spinneret placement plate back to the feeding plate on the conveyor section, and the gear chain mechanism continues to move.

[0025] S5: Vibration Cleaning: When the feeding plate moves close to the vibration cleaning component, the gear chain mechanism stops moving. The corresponding pushing component at the vibration cleaning component pushes the spinneret placement plate onto the support plate at the vibration cleaning component. The support plate descends into the cleaning tank inside the ultrasonic vibrator for vibration cleaning. After cleaning, the support plate rises, and the return component at the vibration cleaning component pushes the vibrated and cleaned spinneret placement plate back onto the feeding plate on the conveyor section. The gear chain mechanism continues to move.

[0026] S6: Rinsing and Cleaning: When the feed plate moves close to the rinsing component, the gear chain mechanism stops moving. The pusher component at the corresponding rinsing component pushes the spinneret placement plate to the rinsing component. The flushing sealing cover inside the rinsing component descends, closing the spinneret placement plate. The spray nozzle sprays high-pressure water to rinse the spinneret. After cleaning, the return component at the rinsing component pushes the rinsed spinneret placement plate back to the feed plate on the conveyor section, and the gear chain mechanism continues to move.

[0027] S7: Drying: When the feeding plate moves close to the drying component, the gear chain mechanism stops moving. The corresponding pushing component at the drying component pushes the spinneret placement plate to the drying component. The hot air blower inside the drying component blows out hot air to dry the moisture inside the spinneret. After drying, the return component at the drying component pushes the rinsed spinneret placement plate back to the feeding plate on the conveyor section. The gear chain mechanism continues to move to the discharge port for discharge.

[0028] S8: Cleaning Inspection: Check the cleaned and dried spinneret. Cleaning is complete once the spinneret is found to be clean. If the spinneret is not completely clean, repeat steps S2 to S8 in sequence.

[0029] The beneficial effects of this invention compared to the prior art are:

[0030] The technical solution of this invention utilizes a conveyor unit to transport spinnerets to be cleaned, and then uses a pusher assembly to sequentially push the spinnerets to be cleaned into various components of the cleaning and drying unit for cleaning or drying. After cleaning or drying, the spinnerets are pushed back to the conveyor unit by the return assembly for the next step. The entire device adopts a production line cleaning method, which can gradually clean multiple spinnerets, is convenient to use, and improves cleaning efficiency.

[0031] During cleaning, the spinneret to be cleaned is initially rinsed with high-pressure hot steam using the steam cleaning unit in the cleaning and drying section. This softens the solidified PAN solution inside the micropores of the spinneret, ensuring thorough cleaning without any blind spots. Then, the spinneret is ultrasonically cleaned using the vibration cleaning unit to dislodge any remaining PAN from the micropores, ensuring a second cleaning effect. Next, the spinneret is high-pressure rinsed using the rinsing unit after vibration cleaning to remove any PAN that has been loosened by the vibration, ensuring a thorough cleaning of the spinneret surface and the inside of the micropores and preventing PAN residue. Finally, the spinneret is dried using the drying unit to prevent moisture residue from causing corrosion. Attached Figure Description

Detailed Implementation

[0048] The following will refer to the appendices in the embodiments of the present invention. Figure 1-15 The technical solutions in the embodiments of the present invention will be described in detail below. Example

[0049] like Figure 1 and 2As shown, a carbon fiber spinneret cleaning device includes a cabinet 1, a conveying unit 2, and a cleaning and drying unit. The conveying unit 2 and the cleaning and drying unit are installed in the cabinet 1. The conveying unit 2 transports the spinneret 9 to be cleaned. The cleaning and drying unit cleans the spinneret 9 and dries it after cleaning. The cleaning and drying unit includes a pushing component 3, a returning component 4, a steam cleaning component 5, a vibration cleaning component 6, a rinsing component 7, and a drying component 8.

[0050] The main function of the cabinet 1 is to serve as the carrier for the installation of the conveying section 2 and the cleaning and drying section, and to protect the conveying section 2 and the cleaning and drying section. The cabinet 1 is made of sheet metal. In order to facilitate installation and maintenance, a cabinet door 14 is provided on one side of the cabinet 1. The cabinet 1 can be opened through the cabinet door 14 to inspect the components inside the cabinet 1.

[0051] To facilitate the placement of the spinneret 9, a rectangular discharge port 12 is provided at one end of the cabinet 1 near the conveying section 2. The spinneret 9 to be cleaned can be placed into the conveying section 2 through the discharge port 12. In addition, to facilitate the observation of the cleaning process, four observation ports 13 are provided on the opposite side of the cabinet door 14 on the cabinet 1. The observation ports 13 correspond to the positions of various components in the cleaning and drying section. Glass is installed on the observation ports 13, and the cleaning process of the spinneret can be observed through the observation ports 13.

[0052] To facilitate overall control of the device, a control box 11 is located at one end of the cabinet 1, through which the entire device can be controlled.

[0053] like Figure 2 , 3 As shown in Figures 4 and 5, the main function of the conveying unit 2 is to transport the spinnerets 9 to be cleaned sequentially to the steam cleaning assembly 5, the vibration cleaning assembly 6, the rinsing assembly 7, and the drying assembly 8.

[0054] The conveying unit 2 includes a conveying frame 201, a gear chain mechanism 202, and a support frame 205. The support frame 205 is a frame made of 40*40 aluminum profile and its main function is to support the conveying frame 201. The conveying frame 201 is a metal frame with a "U" shaped cross section formed by welding three rectangular metal plates together. Two gear chain mechanisms 202 are connected and fixed on the two opposing vertical plates of the conveying frame 201 by mounting shafts.

[0055] The gear chain mechanism 202 is distributed along the length of the conveyor frame 201. A conveyor motor 209 is fixed at one end of the conveyor frame 201 with screws. The conveyor motor 209 is connected to the mounting shaft on the gear chain mechanism 202. The conveyor motor 209 drives the gears in the two opposing gear chain mechanisms 202 to rotate, thereby driving the chain to move.

[0056] To facilitate the transport of the spinneret 9, a feed plate 203 is installed on the chain of the gear chain mechanism 202. The feed plate 203 is a rectangular metal plate, and its length is the same as the size of the opposing chains in the two gear chain mechanisms 202. To facilitate the connection between the feed plate 203 and the chain, a rectangular mounting plate 211 is welded to the back of the feed plate 203 near the edge. The feed plate 203 is fixed to the chain with screws through the mounting plate 211, and the feed plate 203 can move with the chain.

[0057] To facilitate the transfer and cleaning of the spinneret 9, a spinneret placement plate 204 is placed on the feeding plate 203, and the spinneret 9 is placed on the spinneret placement plate 204.

[0058] The spinneret placement plate 204 is a rectangular stainless steel plate with a certain thickness. There are two circular through holes recessed perpendicular to the surface of the spinneret placement plate 204. These through holes are named feeding holes 212. The diameter of the feeding holes 212 is slightly smaller than the diameter of the spinneret 9. In order to facilitate the placement of the spinneret 9, there is a circular shoulder recessed at the feeding hole 212 on the spinneret placement plate 204. The spinneret 9 is placed on the shoulder corresponding to the feeding hole 212. During transportation, cleaning and drying, the spinneret 9 moves together with the spinneret placement plate 204.

[0059] To ensure a tight seal during steam cleaning and water rinsing, a sealing groove 214 is recessed around the outer surface of the feed hole 212 on the upper surface of the spinneret 9 placed on the spinneret placement plate 204. When the steam cleaning component 5 and the rinsing component 7 are working, they cooperate with the sealing groove 214, and the cleaning water and steam can only be discharged through the micro-holes on the spinneret 9, thereby achieving the cleaning effect.

[0060] During cleaning, in order to prevent water accumulation, an "I"-shaped liquid guiding groove 213 is recessed inward on the upper surface of the spinneret placement plate 204 perpendicular to the spinneret placement plate 204. A drain hole is provided in the middle of the liquid guiding groove 213. The cleaning liquid remaining on the spinneret placement plate 204 is collected in the liquid guiding groove 213 and discharged through the drain hole.

[0061] In order to prevent the spinneret placement plate 204 from falling off the feeding plate 203 during the transfer process, two rectangular limiting plates 210 are welded to the upper surface of the feeding plate 203 perpendicular to the feeding plate 203. The extension direction of the limiting plates 210 is perpendicular to the moving direction of the feeding plate 203. The limiting plates 210 can prevent the spinneret placement plate 204 from falling off the feeding plate 203.

[0062] To facilitate the cleaning and drying of the spinneret 9, three feeding plates 206 are fixed to one side of the support frame 205 with screws. The feeding plates 206 correspond to the steam cleaning assembly 5, the vibration cleaning assembly 6, and the drying assembly 8, respectively. The spinneret 9 to be cleaned or dried, together with the spinneret placement plate 204, is pushed out by the pushing assembly 3 and placed on the feeding plate 206, where it is cleaned or dried by the cleaning and drying section.

[0063] The feeding plate 206 is a rectangular metal plate. A rectangular limiting platform 207 protrudes from the upper surface of the feeding plate 206. The limiting platform 207 can restrict the position of the spinneret placement plate 204 placed on it, preventing the spinneret placement plate 204 from falling off the feeding plate 206. In order to facilitate the spinneret placement plate 204 to be pushed into the feeding plate 206 from the feeding plate 203, the limiting platform 207 is not opened on the side of the feeding plate 206 near the support frame 205.

[0064] In addition, to facilitate the cleaning of the spinneret 9 on the spinneret placement plate 204, two circular through holes are made on the feeding plate 206 at the corresponding positions of the feeding holes 212 on the spinneret placement plate 204. These through holes are named functional holes 208. The liquid that falls after cleaning the spinneret 9 is discharged through the functional holes 208.

[0065] like Figure 2 , 5 As shown in Figure 6, the pushing assembly 3 includes a pushing cylinder 31 and a cylinder mounting bracket 32. The pushing cylinder 31 is fixed to the cylinder mounting bracket 32 ​​by screws, and the cylinder mounting bracket 32 ​​is fixed inside the cabinet 1 by screws. The lower end of the cylinder mounting bracket 32 ​​is in contact with the ground.

[0066] The cylinder mounting bracket 32 ​​is a frame made of 40*40 aluminum profile. Its main function is to support the pusher cylinder 31. The pusher cylinder 31 is an existing pneumatic push rod. The pusher head of the pusher cylinder 31 is flush with the feeding plate 203 on the conveying section 2. The pusher cylinder 31 can push the spinneret placement plate 204 on the feeding plate 203 onto the discharge plate 206 for subsequent cleaning and drying.

[0067] The control of the pusher cylinder 31 is achieved through the control box 11 on the cabinet 1. This control method and principle are existing technologies and will not be elaborated here.

[0068] The main function of the return assembly 4 is to push the spinneret placement plate 204, which has been cleaned or dried on the feeding plate 206, back onto the feeding plate 203 so that the next step can be carried out. The return assembly 4 includes a return cylinder 41, a return push plate 42, and a return cylinder mounting plate 43.

[0069] The return cylinder 41 is an existing pneumatic push rod, and the return cylinder mounting plate 43 is an "L"-shaped metal mounting plate. The return cylinder 41 is fixed to the side of the discharge plate 206 by screws through the return cylinder mounting plate 43.

[0070] The return push plate 42 is a metal plate with a "Z" shaped cross section. The horizontal plate at one end of the return push plate 42 is fixed to the push head of the return cylinder 41 with screws, and the horizontal plate at the other end is placed on the feeding plate 206. When the return cylinder 41 extends, it can drive the return push plate 42 to move, thereby pushing the spinneret placement plate 204 on the feeding plate 206 back onto the feeding plate 203.

[0071] like Figure 2 , 7 As shown in Figure 8, the main function of the steam cleaning component 5 is to perform preliminary cleaning on the spinneret 9 to be cleaned. The steam cleaning component 5 can spray high-pressure hot steam, which can easily enter the micropores of the spinneret 9. The temperature of the steam can soften the solidified PAN solution in the micropores, making cleaning convenient.

[0072] The steam cleaning assembly 5 includes a high-pressure steam generator 501, a steam hood 502, and an exhaust box 503. The steam cleaning assembly 5 is located inside the cabinet 1 on the other side of the conveying section 2, near the first discharge plate 206 on the conveying section 2 close to the cabinet 1.

[0073] The high-pressure steam generator 501 is connected to the steam hood 502 through the air inlet pipe 508. The steam hood 502 covers the first discharge plate, and the distance between the two is adjustable. The exhaust box 503 is located below the first discharge plate. The high-temperature and high-pressure steam in the high-pressure steam generator 501 can be discharged through the air inlet pipe 508 and the steam hood 502 to perform steam cleaning on the spinneret placement plate 204 placed on the first discharge plate, thereby softening the solidified PAN solution in the spinneret 9 on the spinneret placement plate 204 and blowing it out.

[0074] The high-pressure steam generator 501 is an existing device that can be used directly. An air inlet pipe 508 is connected to the high-pressure steam generator 501, and a control valve 504 is installed at the high-pressure steam generator 501 and the air inlet pipe 508. The control valve 504 is a solenoid valve, which can control the on / off of steam transmission through the air inlet pipe 508.

[0075] The steam hood 502 includes a fixed hood head and a movable hood head 505. The fixed hood head is a rectangular metal hood with two circular holes. The fixed hood head is connected to the air inlet pipe 508 through a T-shaped pipe. The movable hood head 505 is a rectangular metal hood, and its size is slightly larger than that of the fixed hood head. The movable hood head 505 can cover the fixed hood head, and the movable hood head 505 can move up and down relative to the fixed hood head. The lower end of the lowered movable hood head 505 can cover the spinneret placement plate 204 placed on the feed plate 206 to clean the spinneret 9.

[0076] To ensure the airtight connection between the movable cover 505 and the fixed cover, a rectangular skirt protrudes from the outer wall of the fixed cover and a rectangular skirt protrudes from the inner side of the upper end of the movable cover 505. A sealing gasket is placed at the contact point of the two skirts. When the movable cover 505 moves down, the two skirts of the movable cover 505 and the fixed cover come into contact to prevent air leakage.

[0077] After the lower end of the movable cover 505 covers the spinneret placement plate 204, in order to improve the sealing performance, a rectangular sealing platform 509 protrudes outward on the lower end surface of the movable cover 505. The sealing platform 509 can cooperate with the sealing groove 214 on the spinneret placement plate 204 to seal and prevent air leakage.

[0078] To facilitate adjustment of the gap between the movable cover 505 and the fixed cover, a cylinder is fixed to the fixed cover with screws. This cylinder is named the first lifting cylinder 513. The push end of the first lifting cylinder 513 is connected to the upper end of the movable cover 505 with screws. The gap between the movable cover 505 and the fixed cover can be adjusted through the first lifting cylinder 513.

[0079] To facilitate the direct steam blowing onto the spinneret 9 on the spinneret placement plate 204, two conical steam nozzles 506 are welded onto the movable cover head 505. The opening diameter of the lower end of the steam nozzle 506 is larger than the diameter of the spinneret 9, and the steam nozzle 506 can cover the outside of the spinneret 9.

[0080] To facilitate the raising and lowering of the steam nozzle 506 with the movable cover 505, a circular groove is recessed on the inner side of the opening at the upper end of the steam nozzle 506, which is named the sealing groove 510. At the same time, an air inlet connector 512 is inserted into each of the two circular openings on the fixed cover, which is connected to the tee pipe on the air inlet pipe 508. An annular sealing ring 514 protrudes from the outer wall of the end of the air inlet connector 512. When the steam nozzle 506 descends with the movable cover 505, the sealing ring can cooperate with the sealing groove 510 on the steam nozzle 506 to seal and prevent air leakage. To improve the sealing performance, a high-temperature resistant sealing gasket is placed at the joint between the steam nozzle 506 and the air inlet connector 512.

[0081] The exhaust box 503 is a hollow rectangular box. Its main function is to receive the steam after it passes through the micro-holes on the spinneret 9. In order to prevent clogging, a filter screen 507 is fixed to the upper end of the exhaust box 503 with screws. The filter screen 507 can filter the steam entering the exhaust box 503 and block the impurities blown out with the steam.

[0082] In order to expel the steam in the exhaust box 503 in a timely manner, an exhaust port 511 is provided on the exhaust box 503. An exhaust pipe connected to the outside can be installed on the exhaust port 511, and the steam in the exhaust box 503 can be discharged through the exhaust pipe.

[0083] Regarding the cleaning process of the steam cleaning assembly 5: When the conveying unit 2 transports the spinneret placement plate 204 containing the spinneret 9 to the steam cleaning assembly 5, the pushing cylinder 31 in the corresponding pushing assembly 3 of the steam cleaning assembly 5 pushes the spinneret placement plate 204 onto the discharge plate 206. The upper limit plate 207 of the discharge plate 206 restricts the position of the spinneret placement plate 204. Then, the first lifting cylinder 513 drives the movable cover head 505 to descend. The sealing plate 509 on the movable cover head 505 cooperates with the sealing groove 214 on the spinneret placement plate 204 to seal. Then, the control valve 504 pressurizes the steam... High-temperature compressed steam is released from the steam generator 501, and high-pressure hot steam is ejected through the steam nozzle 506. The high-pressure steam can easily enter the micropores of the spinneret 9. The temperature of the steam can soften the solidified PAN solution in the micropores and blow the softened and loosened PAN out of the micropores. After steam rinsing for 15 minutes, the steam ejection stops, the movable hood 505 rises, and then the return cylinder 41 at the steam cleaning component 5 extends, driving the return push plate 42 to move, thereby pushing the spinneret placement plate 204 on the discharge plate 206 back into the feeding plate 203 for the next cleaning process.

[0084] like Figure 2 , 9 As shown in Figure 10, the vibration cleaning assembly 6 includes an ultrasonic vibrator 61 and a material support plate 62. The ultrasonic vibrator 61 is fixed on a vibrator support frame 63, the lower end of which is placed on the ground. The material support plate 62 is placed inside the ultrasonic vibrator 61 and can be raised and lowered relative to the ultrasonic vibrator 61.

[0085] The vibrator support frame 63 is a frame made of 40*40 aluminum profile. Its main function is to support the ultrasonic vibrator 61, which is an existing device that can be used directly.

[0086] The main function of the ultrasonic vibrator 61 is to perform ultrasonic vibration cleaning on the spinneret 9 after steam cleaning. The vibration tank of the ultrasonic vibrator 61 contains cleaning fluid. During vibration cleaning, the material support plate 62 carries the spinneret 9 in the cleaning fluid. The high-frequency vibration vibrates out the PAN solids softened by the steam cleaning component 5 in the micropores of the spinneret 9, and performs secondary cleaning on some impurities that have not fallen off, thereby improving the cleaning effect.

[0087] The material support plate 62 is a metal plate with a rectangular cross-section. The main function of the material support plate 62 is to support the spinneret placement plate 204 on which the spinneret 9 is placed. Under the action of the pusher assembly 3, the spinneret placement plate 204 moves from the feed plate 203 to the material support plate 62. In order to improve the cleaning effect, two circular through holes are opened on the material support plate 62, which correspond to the material discharge holes 212 on the spinneret placement plate 204.

[0088] To facilitate the control of the lifting and lowering of the material support plate 62, two "U"-shaped material support plate connecting plates 64 are welded on two adjacent sides of the material support plate 62. The material support plate connecting plates 64 can be directly clipped onto the frame of the ultrasonic vibrator 61. A second lifting cylinder 65 is fixed to the outside of the ultrasonic vibrator 61 with screws. The push head of the second lifting cylinder 65 is connected to the material support plate connecting plates 64 by screws. When the second lifting cylinder 65 rises, it can drive the material support plate 62 to rise and fall. When the material support plate 62 rises to its highest point, it can be flush with the height of the feeding plate 203 on the conveying section 2.

[0089] like Figure 2 , 11 As shown in Figure 12, the rinsing assembly 7 includes a rinsing mechanism 71 and a rinsing sealing mechanism 72. The main function of the rinsing assembly 7 is to perform high-pressure rinsing on the spinneret 9 after vibration cleaning, and to rinse off the loose and residual PAN debris on the surface of the spinneret 9 and in the micropores.

[0090] The flushing mechanism 71 includes an inlet pipe 73 and a water storage tank 74. The inlet pipe 73 is connected to the water storage tank 74 via a water pump, and the water pump pumps water from the water storage tank 74 into the inlet pipe 73.

[0091] The flushing sealing mechanism 72 includes a flushing sealing cover 75, a fixed plate 78, and a third lifting cylinder 79. The fixed plate 78 is connected to the water inlet pipe 73. The flushing sealing cover 75 is connected to the fixed plate 78 through the third lifting cylinder 79. The distance between the flushing sealing cover 75 and the fixed plate 78 can be adjusted through the third lifting cylinder 79.

[0092] The fixing plate 78 is a rectangular metal plate. A three-way pipe is welded on the fixing plate 78. The upper end of the three-way pipe is connected to the water inlet pipe 73. A corrugated pipe 76 is fixedly connected to the other two lower interfaces (the connection method can be clamps or other existing technologies to ensure that there is no water leakage). A conical spray head 77 is installed at the end of the corrugated pipe 76. The water in the water tank 74 is transmitted through the water inlet pipe 73 and sprayed out through the spray head 77 under the action of the water pump. When the spinneret placement plate 204 moves to the top of the discharge plate 206 near the flushing component 7 under the action of the pusher assembly 3, the flushing sealing cover 75 is lowered under the action of the third lifting cylinder 79. High-pressure water is sprayed onto the spinneret 9 on the spinneret placement plate 204 through the spray head 77 for cleaning.

[0093] To prevent water leakage during rinsing, the lower end of the rinsing sealing cover 75 is also provided with a sealing platform that can cooperate with the sealing groove 214 on the spinneret placement plate 204. When the rinsing sealing cover 75 contacts the spinneret placement plate 204, the lower end of the rinsing sealing cover 75 is stuck in the sealing groove 214 to prevent water leakage.

[0094] To facilitate the collection of water used by the rinsing assembly 7, a water storage tank 74 is placed below the discharge plate 206 near the rinsing assembly 7. The upper opening of the water storage tank 74 is connected to the lower surface of the discharge plate 206 with screws. The water storage tank 74 can store and collect the water sprayed by the rinsing assembly 7. In order to facilitate the recycling of rinsing water, a filter screen (not shown in the figure) is installed above the water storage tank 74. The filter screen filters and collects impurities in the water, which can then be recycled to avoid wasting water resources.

[0095] like Figure 2 , 13 As shown in 14 and 15, the drying assembly 8 includes a drain box 81 and a hot air blower 82. The hot air blower 82 is fixed to the drain box 81 with screws by a hot air blower mounting bracket 83. The drain box 81 is placed below the discharge plate 206 near the drying assembly 8.

[0096] The main function of the drying component 8 is to dry the spinneret 9 after it has been rinsed by the rinsing component 7, so as to prevent moisture residue from causing the spinneret 9 to rust.

[0097] The drain box 81 is placed below the discharge plate 206 near the drying component 8, and mainly collects the water drained from the spinneret 9.

[0098] The hot air blower 82 is an existing hot air blower that can blow air. Its main function is to blow out hot air to dry the moisture on the spinneret 9 and ensure that the spinneret 9 is dry.

[0099] The hot air blower mounting bracket 83 is an "L"-shaped metal plate. The lower end of the vertical plate of the hot air blower mounting bracket 83 is connected to the upper end of the drain box 81 with screws. The hot air blower 82 is installed on the horizontal plate above the hot air blower mounting bracket 83 with screws. After installation, there is a certain distance between the hot air blower 82 and the upper end of the drain box 81. The discharge plate 206 near the drying component 8 is located here.

[0100] To facilitate the airflow from the hot air blower 82 to the spinneret 9, an air guide box 84 is installed on the horizontal plate at the upper end of the hot air blower mounting bracket 83, near the hot air blower 82. The air guide box 84 is a hollow metal box with an "L"-shaped cross-section. The upper end of the air guide box 84 with a smaller cross-section is fixed to the hot air blower mounting bracket 83 with screws. The hot air blower 82 is connected to the side of the air guide box 84. Two air outlets 85 are opened on the lower end face of the air guide box 84 with a larger cross-section. The hot air blown out by the hot air blower 82 is guided by the air guide box 84 and blown out from the air outlets 85 to dry the spinneret 9.

[0101] The cleaning method of the carbon fiber spinneret cleaning device of the present invention specifically includes the following steps:

[0102] S1: Material removal: Remove the spinneret 9 from the spinneret;

[0103] S2: Feeding: Place the spinneret 9 on the feeding hole 212 on the spinneret placement plate 204, and the spinneret 9 is placed with the larger cross-section inlet 91 facing down and the smaller cross-section outlet 92 facing up. Then place the spinneret placement plate 204 on the feeding plate 203 of the conveying section 2.

[0104] S3: Start: Start the equipment. The gear chain mechanism 202 on the conveyor section 2 drives the spinneret placement plate 204 to move forward.

[0105] S4: Steam cleaning: When the feeding plate 203 moves close to the steam cleaning component 5, the gear chain mechanism 202 stops moving. The corresponding pushing component 3 at the steam cleaning component 5 pushes the spinneret placement plate 204 to the steam cleaning component 5. The steam hood 502 inside the steam cleaning component 5 descends, closing the spinneret placement plate 204. The steam nozzle 506 sprays high-pressure hot steam to clean the spinneret 9. After cleaning, the return component 4 at the steam cleaning component 5 pushes the steam-cleaned spinneret placement plate 204 back to the feeding plate 203 on the conveying section 2, and the gear chain mechanism 202 continues to move.

[0106] S5: Vibration Cleaning: After steam cleaning is completed, when the feeding plate 203 moves close to the vibration cleaning component 6, the gear chain mechanism 202 stops moving. The corresponding pushing component 3 at the vibration cleaning component 6 pushes the spinneret placement plate 204 onto the support plate 62 at the vibration cleaning component 6. The support plate 62 descends into the cleaning tank inside the ultrasonic vibrator 61 for vibration cleaning. After cleaning is completed, the support plate 62 rises, and the return component 4 at the vibration cleaning component 6 pushes the vibrated spinneret placement plate 204 back to the feeding plate 203 on the conveying section 2. The gear chain mechanism 202 continues to move.

[0107] S6: Rinsing and Cleaning: After the vibration cleaning is completed, when the feeding plate 203 moves close to the rinsing component 7, the gear chain mechanism 202 stops moving. The corresponding pushing component 3 at the rinsing component 7 pushes the spinneret placement plate 204 to the rinsing component 7. The flushing sealing cover 75 inside the rinsing component 7 descends, sealing the spinneret placement plate 204. The water spray head 77 sprays high-pressure water to rinse the spinneret 9. After cleaning is completed, the return component 4 at the rinsing component 7 pushes the rinsed spinneret placement plate 204 back to the feeding plate 203 on the conveying section 2, and the gear chain mechanism 202 continues to move.

[0108] S7: Drying: After rinsing, when the feeding plate 203 moves close to the drying component 8, the gear chain mechanism 202 stops moving. The corresponding pushing component 3 at the drying component 8 pushes the spinneret placement plate 204 to the drying component 8. The hot air blower 82 inside the drying component 8 blows out hot air to dry the moisture in the spinneret 9. After drying, the return component 4 at the drying component 8 pushes the rinsed spinneret placement plate 204 back to the feeding plate 203 on the conveying section 2. The gear chain mechanism 202 continues to move to the discharge port and discharges the material.

[0109] S8: Cleaning Inspection: Inspect the cleaned and dried spinneret 9. Cleaning is complete if the spinneret 9 is found to be clean. If the spinneret 9 is not completely clean, repeat steps S2 to S8 in sequence.

[0110] Advantages of this embodiment: The cleaning process in this embodiment adopts a production line approach, sequentially performing high-pressure hot steam cleaning, vibration cleaning, high-pressure water jet rinsing, and drying. This ensures the cleaning effect while improving cleaning efficiency, avoids manual cleaning, and is convenient to use.

[0111] The above embodiments are merely illustrative of the technical concept of the present invention and should not be construed as limiting the scope of protection of the present invention. Any modifications made to the technical solutions based on the technical concept proposed in this invention shall fall within the scope of protection of this invention.
