Description

Technical Field

[0001] The invention specifically relates to a carbon fiber spinneret cleaning device. Background Art

[0002] The carbon fiber spinneret is a key component in the carbon fiber production process. Its function is to extrude the carbon fiber precursor material polyacrylonitrile (PAN) solution or melt through micropores to form fibers. These fibers will then undergo a series of treatment processes, including pre-oxidation, carbonization, etc., to finally form carbon fibers.

[0003] During the process of extruding carbon fiber spinnerets to form fibers, some materials will remain inside the micropores on the spinneret to form blockages. In order to ensure the quality of the carbon fiber, the micropores in the spinneret need to be cleaned at regular intervals. There are various ways to clean the micropores inside the carbon fiber spinneret. Traditional high-temperature calcination cleaning and chemical cleaning methods will damage the spinneret after long-term use. Therefore, most of the existing technologies use water particle cleaning to treat it. Water particle cleaning uses room temperature tap water converted into a particle state to physically clean the spinneret, avoiding the high-temperature treatment process of the traditional cleaning process. The treated mold does not have problems such as deformation, cracks, and chemical damage.

[0004] When the prior art uses water particles for cleaning, pressurized water is generally made to flow through the micropores inside the carbon fiber spinneret. By increasing the water pressure, the attachments attached to the side walls of the feed hole and the discharge hole can be effectively removed. However, since a conical structure connecting hole connecting the feed hole and the discharge hole is provided inside the spinneret micropores, the conical structure part cannot be cleaned during the water flow. Instead, the cleaned attachments will be deposited on the conical part. After long-term use, accumulation will form, affecting the spinning effect of the carbon fiber spinneret.

After the cleaning agent is sprayed out of the spinneret, the spinneret is moved to the quick connector inside the cleaning tank, and the spinneret and its components are connected to the quick connector, and then the cleaning agent starts to circulate for the second time to clean the spinneret, and further wash the residual slurry in the spinneret holes of the spinneret.

[0006] As shown in the attached figure of Patent: 202110217188.5, this patent mainly utilizes a combination of chemical reagents and ultrasonic cleaning. Chemical reagents are first used for preliminary cleaning, and then ultrasound is used for secondary cleaning. This patent can play the role of cleaning the spinneret, but chemical reagents are easy to corrode the spinneret. At the same time, the patented cleaning device can only clean one spinneret at a time, and the efficiency is low. Summary of the invention

DETAILED DESCRIPTION

[0022] The following will be combined with the attached embodiment of the present invention Figure 1-15 , the technical solutions in the embodiments of the present invention are described in detail. Example

[0023] like Figure 1 and 2 As shown, a carbon fiber spinneret cleaning device includes a cabinet 1, a conveying part 2 and a cleaning and drying part. The conveying part 2 and the cleaning and drying part are installed in the cabinet 1. The conveying part 2 transports the spinneret 9 to be cleaned, and the cleaning and drying part cleans the spinneret 9 and dries it after cleaning. The cleaning and drying part includes a pushing component 3, a returning component 4, a steam cleaning component 5, a vibration cleaning component 6, a flushing component 7 and a drying component 8.

[0024] The main function of the cabinet 1 is to serve as a carrier for installing the conveying part 2 and the cleaning and drying part, and to protect the conveying part 2 and the cleaning and drying part. The cabinet 1 is made of metal plate sheet metal as a whole. In order to facilitate installation and maintenance, a cabinet door 14 is opened 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.

[0025] In order 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 portion 2, through which the spinneret 9 to be cleaned can be placed on the conveying portion 2. In addition, in order to facilitate the observation of the cleaning process, four observation ports 13 are provided on the opposite surface of the cabinet door 14 of the cabinet 1. The observation ports 13 correspond to the positions of various components in the cleaning and drying portion, and glass is installed on the observation ports 13, through which the spinneret cleaning process can be observed.

[0026] In order to facilitate the control of the entire device, a control box 11 is provided at one end of the cabinet 1 , through which the entire device can be controlled.

[0027] like Figure 2 , 3 As shown in FIGS. 4 and 5 , the main function of the conveying part 2 is to transport the spinneret 9 to be cleaned to the steam cleaning component 5 , the vibration cleaning component 6 , the flushing component 7 and the drying component 8 in sequence.

[0028] The conveying part 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 profiles. Its main function is to support the conveying frame 201. The conveying frame 201 is a metal frame with a "U"-shaped cross-section composed of three rectangular metal plates welded together. Two gear chain mechanisms 202 are connected and fixed on two oppositely distributed vertical plates of the conveying frame 201 using mounting shafts.

[0029] The gear chain mechanism 202 is distributed along the length of the conveying frame 201. A conveying motor 209 is fixed to one end of the conveying frame 201 by screws. The conveying motor 209 is connected to the mounting shaft on the gear chain mechanism 202. The conveying motor 209 drives the gears in the two sets of oppositely distributed gear chain mechanisms 202 to rotate and then drives the chain to move.

[0030] In order to facilitate the transportation of the spinneret 9, a feeding plate 203 is installed on the chain of the gear chain mechanism 202. The feeding plate 203 is a rectangular metal plate. The length of the feeding plate 203 is the same as the size of the chains distributed oppositely in the two gear chain mechanisms 202. In order to facilitate the connection between the feeding plate 203 and the chain, a rectangular mounting plate 211 is welded on the back side of the feeding plate 203 near the edge. The feeding plate 203 is fixed to the chain by screws through the mounting plate 211, and the feeding plate 203 can move with the chain.

[0031] In order to facilitate the transfer and cleaning of the spinneret 9 , a spinneret placement plate 204 is placed on the feed plate 203 , and the spinneret 9 is placed on the spinneret placement plate 204 .

[0032] The spinneret placement plate 204 is a stainless steel rectangular plate with a certain thickness. There are two circular through holes on the surface of the spinneret placement plate 204 that are perpendicular to the spinneret placement plate 204 and are recessed. These through holes are named discharge holes 211. The diameter of the discharge hole 211 is slightly smaller than the diameter of the spinneret 9. In order to facilitate the placement of the spinneret 9, a circular shoulder is recessed at the discharge hole 211 on the spinneret placement plate 204. The spinneret 9 is placed on the shoulder and corresponds to the discharge hole 211. The spinneret 9 moves with the spinneret placement plate 204 during transportation, cleaning and drying.

[0033] In order to ensure the sealing during steam cleaning and water flushing, a sealing groove 214 is formed on the upper surface of the spinneret 9 on the spinneret placing plate 204, and the outside of the discharge hole 211 is concave along the outline of the spinneret placing plate 204. The steam cleaning component 5 and the flushing component 7 cooperate with the sealing groove 214 during operation, and the cleaning water and steam can only be discharged through the micropores on the spinneret 9, thereby achieving a cleaning effect.

[0034] During cleaning, in order to prevent water accumulation, an I-shaped liquid guide groove 213 is provided on the upper surface of the spinneret plate 204 and is concavely provided perpendicularly to the spinneret plate 204. A drainage hole is provided in the middle of the liquid guide groove 213. The cleaning liquid remaining on the spinneret plate 204 is collected through the liquid guide groove 213 and then discharged through the drainage hole.

[0035] In order to prevent the spinneret placement plate 204 from falling off the feed plate 203 during the transportation process, two rectangular limit plates 210 are welded on the upper surface of the feed plate 203 perpendicular to the feed plate 203 and opposite to each other. The extension direction of the limit plates 210 is perpendicular to the moving direction of the feed plate 203. The limit plates 210 can prevent the spinneret placement plate 204 from falling off the feed plate 203.

[0036] In order to facilitate the cleaning and drying of the spinneret 9, three discharge plates 206 are fixed with screws on one side of the support frame 205. The discharge plates 206 correspond to the steam cleaning component 5, the flushing component 6 and the drying component 8 respectively. The spinneret 9 to be cleaned or dried is pushed out together with the spinneret placing plate 204 by the pushing component 9 and placed on the discharge plate 206, and is cleaned or dried by the cleaning and drying part.

[0037] The discharge plate 206 is a rectangular metal plate, and a rectangular limit platform 207 is protruding from the upper surface of the discharge plate 206. The limit platform 207 can limit the position of the spinneret placement plate 204 placed thereon to prevent the spinneret placement plate 204 from falling off the discharge plate 206. In order to facilitate the spinneret placement plate 204 to be pushed from the feed plate 203 into the discharge plate 206, the limit platform 207 is not opened on the side of the discharge plate 206 close to the support frame 205.

[0038] In addition, in order to facilitate the cleaning of the spinneret 9 on the spinneret placement plate 204, two circular through holes are opened on the discharge plate 206 corresponding to the discharge hole 211 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.

[0039] like Figure 2 , 5 As shown in Figure 6, the pushing assembly 3 includes a pushing cylinder 31 and a cylinder mounting frame 32. The pushing cylinder 31 is fixed to the cylinder mounting frame 32 by screws. The cylinder mounting frame 32 is fixed in the cabinet 1 by screws, and the lower end of the cylinder mounting frame 32 is in contact with the ground.

[0040] The cylinder mounting frame 32 is a frame made of 40*40 aluminum profile, and its main function is to support the pushing cylinder 31. The pushing cylinder 31 is an existing pneumatic push rod. The pushing head of the pushing cylinder 31 is flush with the feeding plate 203 on the conveying part 2. The pushing cylinder 31 can push the spinneret placement plate 204 on the feeding plate 203 to the discharge plate 206 for subsequent cleaning and drying.

[0041] The control of the push cylinder 31 is carried out through the control box 11 on the cabinet 1. The control method and principle are prior art and will not be described in detail here.

[0042] The main function of the return material component 4 is to push the spinneret placement plate 204 placed on the discharge plate 206 after cleaning or drying back to the feed plate 203 for the next step. The return material component 4 includes a return material cylinder 41, a return material push plate 42 and a return material cylinder mounting plate 43.

[0043] 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.

[0044] The return material push plate 42 is a metal plate with a "Z"-shaped cross-section. The horizontal plate at one end of the return material push plate 42 is fixed to the push head of the return material cylinder 41 by screws, and the horizontal plate at the other end is placed on the discharge plate 206. When the return material cylinder 41 is extended, it can drive the return material push plate 42 to move, and then push the spinneret placement plate 204 on the discharge plate 206 back to the feed plate 203.

[0045] 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, and 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, making cleaning convenient.

[0046] 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 arranged in the cabinet 1 at the other side of the conveying part 2 , and at the first discharge plate 206 on the conveying part 2 close to the cabinet 1 .

[0047] The high-pressure steam generator 501 is connected to the steam hood 502 through the air inlet pipe 508. The steam hood 502 is covered above 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 steam clean 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.

[0048] The high-pressure steam generator 501 is an existing device and can be used directly. An air intake pipe 508 is connected to the high-pressure steam generator 501, and a control valve 504 is installed between the high-pressure steam generator 501 and the air intake pipe 508. The control valve 504 is an electromagnetic valve, and the control valve 504 can control the on and off of steam transmission in the air intake pipe 508.

[0049] 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 three-way pipe. The movable hood head 505 is a rectangular metal hood. The size of the movable hood head 505 is slightly larger than the fixed hood head. The movable hood head 505 can be covered on 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 movable hood head 505 that moves downward can be covered on the spinneret placement plate 204 placed on the discharge plate 206 to clean the spinneret 9.

[0050] In order to ensure the sealing of the connection between the movable cover head 505 and the fixed cover head, a rectangular skirt is protruded on the outer wall of the fixed cover head, and a rectangular skirt is protruded on the inner side of the upper end of the movable cover head 505. A sealing gasket is placed at the contact point of the two skirts. When the movable cover head 505 moves downward, the two skirts of the movable cover head 505 and the fixed cover head are in contact to prevent air leakage.

[0051] When the lower end of the movable cover head 505 is covered on the spinneret placement plate 204, in order to improve the sealing performance, a rectangular sealing platform 509 is protruded outward on the lower end surface of the movable cover head 505. The sealing platform 509 can cooperate with the sealing groove 214 on the spinneret placement plate 204 to seal and prevent air leakage.

[0052] In order to facilitate the adjustment of the interval between the movable cover head 505 and the fixed cover head, a cylinder is fixed on the fixed cover head with screws. This cylinder is named the first lifting cylinder 513. The push head end of the first lifting cylinder 513 is connected to the upper end of the movable cover head 505 with screws. The interval between the movable cover head 505 and the fixed cover head can be adjusted through the first lifting cylinder 513.

[0053] In order to facilitate the guidance of steam to blow directly onto the spinneret 9 on the spinneret placement plate 204, two conical steam nozzles 506 are welded on the movable cover head 505. The opening diameter at the lower end of the steam nozzle 506 is larger than the diameter of the spinneret 9, and the steam nozzle 506 can be covered on the outside of the spinneret 9 as a whole.

[0054] In order to facilitate the steam nozzle 506 to rise and fall with the movable cover head 505, a circular groove is concave on the inner side surface of the opening at the upper end of the steam nozzle 506, and this groove is named as a sealing groove 510. At the same time, an air intake joint 512 connected with the three-way pipe on the air intake pipe 508 is inserted into each of the two circular openings on the fixed cover head. An annular sealing ring 514 is convex on the outer wall of the end of the air intake interface 512. When the steam nozzle 506 descends with the movable cover head 505, the sealing ring can cooperate with the sealing groove 510 on the steam nozzle 506 to seal and prevent air leakage. In order to improve the sealing performance, a high-temperature resistant sealing gasket is covered at the overlap between the steam nozzle 506 and the air intake interface 512.

[0055] The exhaust box 503 is a hollow rectangular box, and its main function is to receive the steam after passing through the micropores on the spinneret 9. In order to prevent blockage, a filter 507 is fixed to the upper end of the exhaust box 503 with screws. The filter 507 can filter the steam entering the exhaust box 503 and intercept the debris blown out with the steam.

[0056] In order to discharge the steam in the exhaust box 503 in time, an exhaust port 511 is opened 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.

[0057] Regarding the cleaning process of the steam cleaning component 5: when the conveying part 2 transports the spinneret placement plate 204 equipped with the spinneret 9 to the steam cleaning component 5, the pushing cylinder 31 in the pushing component 3 of the corresponding steam cleaning component 5 pushes the spinneret placement plate 204 onto the discharge plate 206, and the upper limit table 207 of the discharge plate 206 limits the position of the spinneret placement plate 204, and then the first lifting cylinder 513 drives the movable cover head 505 to descend, and the sealing table 509 on the movable cover head 505 cooperates with the sealing groove 214 on the spinneret placement plate 204 to seal, and then the control valve 504 puts the high-pressure steam The high-temperature compressed steam in the steam generator 501 is released, and the high-pressure hot steam is sprayed out 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 15 minutes of steam flushing, the steam spraying is stopped, the movable cover head 505 rises, and then the return cylinder 41 at the steam cleaning component 5 extends, driving the return push plate 42 to move, and then the spinneret placement plate 204 on the discharge plate 206 is pushed back into the feed plate 203 for the next cleaning process.

[0058] like Figure 2 , 9 As shown in 10 , the vibration cleaning assembly 6 includes an ultrasonic vibrator 61 and a supporting plate 62 . The ultrasonic vibrator 61 is fixed on a vibrator support frame 63 . The lower end of the vibrator support frame 63 is placed on the ground. The supporting plate 62 is placed in the ultrasonic vibrator 61 , and the supporting plate 62 can be raised and lowered relative to the ultrasonic vibrator 61 .

[0059] The vibrator support frame 63 is a frame made of 40*40 aluminum profiles, and its main function is to support the ultrasonic vibrator 61. The ultrasonic vibrator 61 is an existing device and can be used directly.

[0060] The main function of the ultrasonic vibrator 61 is to ultrasonically clean the spinneret 9 after steam cleaning. Cleaning liquid is placed in the vibration pool of the ultrasonic vibrator 61. During vibration cleaning, the support plate 62 carries the spinneret 9 in the cleaning liquid. The PAN solid softened by the steam cleaning component 5 in the micropores of the spinneret 9 is vibrated out through high-frequency vibration, and some impurities that have not fallen off are cleaned for the second time, thereby improving the cleaning effect.

[0061] The support plate 62 is a metal plate with a rectangular cross-section. The main function of the support plate 62 is to support the spinneret placement plate 204 on which the spinneret 9 is placed. The spinneret placement plate 204 moves from the feed plate 203 to the support plate 62 under the action of the pushing assembly 3, and in order to improve the cleaning effect, two circular through holes corresponding to the discharge holes 212 on the spinneret placement plate 204 are opened on the support plate 62.

[0062] In order to facilitate the control of the lifting and lowering of the supporting plate 62, two "U"-shaped supporting plate connecting plates 64 are welded on two adjacent side surfaces of the supporting plate 62. The supporting plate connecting plates 64 can be directly clamped on 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 supporting plate connecting plate 64 by screws. When the second lifting cylinder 65 rises, it can drive the supporting plate 62 to rise and fall. When the supporting plate 62 rises to the highest point, it can be flush with the feeding plate 203 on the conveying part 2.

[0063] like Figure 2 , 11 As shown in FIG. 12 , the flushing assembly 7 includes a flushing mechanism 71 and a flushing sealing mechanism 72 . The main function of the flushing assembly 7 is to perform high-pressure flushing on the spinneret 9 after vibration cleaning, so as to flush away the loose PAN debris remaining on the surface of the spinneret 9 and in the micropores.

[0064] The flushing mechanism 71 includes a water inlet pipe 73 and a water storage tank 74 . The water inlet pipe 73 is connected to the water storage tank 74 through a water pump. The water pump pumps the water in the water storage tank 74 into the water inlet pipe 73 .

[0065] The flushing sealing mechanism 72 includes a flushing sealing cover 75, a fixing plate 78 and a third lifting cylinder 79. The fixing plate 78 is connected to the water inlet pipe 73. The flushing sealing cover 75 is connected to the fixing plate 78 through the third lifting cylinder 79. The distance between the flushing sealing cover 75 and the fixing plate 78 can be adjusted through the third lifting cylinder 79.

[0066] The fixing plate 78 is a rectangular metal plate, on which a three-way pipe is welded. The upper ends of the three channels are connected to the water inlet pipe 73, and the other two lower end interfaces are each fixedly connected with a bellows 76 (the connection method can be connected by a clamp or other existing technology to ensure that there is no water leakage). A conical water spray head 77 is installed at the end of the bellows 76. The water in the water tank 74 is transmitted through the water inlet pipe 73 under the action of the water pump and sprayed out through the water spray head 77. When the spinneret placement plate 204 moves to above the discharge plate 206 near the flushing assembly 7 under the action of the pushing assembly 3, the flushing sealing cover 75 descends under the action of the third lifting cylinder 79, and the spinneret 9 on the spinneret placement plate 204 is sprayed with high-pressure water for cleaning through the water spray head 77.

[0067] In order to prevent water leakage during flushing, a sealing platform is also provided at the lower end of the flushing sealing cover 75 which can cooperate with the sealing groove 214 on the spinneret placement plate 204. When the flushing sealing cover 75 contacts the spinneret placement plate 204, the lower end of the flushing sealing cover 75 is stuck in the sealing groove 214 to prevent water leakage.

[0068] In order to facilitate the collection of water during flushing of the flushing component 7, the water tank 74 is placed below the discharge plate 206 near the flushing component 7, and the upper opening of the water tank 74 is connected to the lower surface of the discharge plate 206 by screws. The water sprayed by the flushing component 7 can be stored and collected by the water tank 74, and in order to facilitate the recycling of flushing water, a filter net (not shown in the figure) is installed above the water tank 74. Impurities in the water are filtered and collected through the filter net and recycled to avoid waste of water resources.

[0069] like Figure 2 , 13 As shown in FIGS. 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 by screws through a hot air blower mounting frame 83 . The drain box 81 is placed under the discharge plate 206 near the drying assembly 8 .

[0070] The main function of the drying component 8 is to dry the spinneret 9 after being flushed by the flushing component 7 to prevent the spinneret 9 from being rusted due to residual moisture.

[0071] The drain box 81 is placed below the discharge plate 206 near the drying assembly 8, and is mainly used to collect water drained from the spinneret 9.

[0072] The hot air blower 82 is an existing hot air blower capable of blowing air, and 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.

[0073] The hot air blower mounting frame 83 is an "L"-shaped metal plate. The lower end of the vertical plate of the hot air blower mounting frame 83 is connected to the upper end of the drain box 81 by screws. The hot air blower 82 is installed on the horizontal plate above the hot air blower mounting frame 83 by screws. After installation, the hot air blower 82 is at a certain distance from the upper end of the drain box 81, and the discharge plate 206 near the drying component 8 is located here.

[0074] In order to facilitate directing the wind 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 frame 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 frame 83 with screws. The hot air blower 82 is connected to the side of the air guide box 84, and two air outlets 85 are provided on the lower end surface 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 then blown out from the air outlet 85 to dry the spinneret 9.
