Description

Technical Field

[0001] The invention relates to the technical field of carbon fiber production, and in particular to a high-temperature carbonization device for carbon fiber production. Background Art

[0002] In the production process of carbon fiber, the precursor needs to undergo pre-oxidation and carbonization processes to change its molecular structure to form a carbon fiber structure. Therefore, pre-oxidation and carbonization processes are key process links in the production process of carbon fiber. Among them, the carbonization process of carbon fiber is divided into low-temperature carbonization and high-temperature carbonization. Different carbonization equipment is required in different carbonization stages. Among them, the high-temperature carbonization process is the process in which the polyacrylonitrile precursor completes the thermal decomposition and generates high-quality carbon fibers. The temperature range of the high-temperature carbonization process is generally between 800-1600°C. During the high-temperature carbonization process, the polyacrylonitrile precursor completes the final stage of decomposition to form HCN or N 2 The residual nitrogen element is released in a manner to obtain a carbon fiber with a carbon content of more than 95% and a turbostratic graphite stacking structure.

[0003] Chinese patent publication number CN106283274B discloses "a high-temperature carbonization device for producing carbon fiber", including a furnace body, a sealing device connected to both ends of the furnace body, an exhaust system and a protective gas supply device connected to the furnace of the furnace body, and also includes a cooling chamber connected to the fiber bundle outlet end of the furnace body through a non-contact sealing device, and a temperature detection control device connected to the temperature sensor and heating device of the furnace body through a temperature detection circuit and a temperature control circuit respectively. The low-temperature carbonization device provided by the patent is provided with a cooling chamber at the outlet end of the furnace body, which can effectively reduce the temperature of the fiber bundle pulled out of the furnace body, prevent the high-temperature fiber bundle that has been carbonized from being oxidized by oxygen in the air, and improve the quality of the carbon fiber. At the same time, the patent installs a temperature sensor inside the furnace body to monitor and control the temperature inside the furnace body in real time.

[0004] However, the prior art has the following problems:

[0005] 1. In some prior arts, when placing the raw silk into the carbonization furnace, the staff is usually required to first pull one end of the raw silk so that the one end of the raw silk passes through the interior of the carbonization furnace. After starting the carbonization furnace, the staff is then required to pull one end of the raw silk through a related device so that the raw silk slowly passes through the interior of the carbonization furnace. When one end of the raw silk passes through the interior of the carbonization furnace, the operation is inconvenient, and a section of the raw silk passing through the interior of the carbonization furnace has a shortened movement time in the carbonization furnace, resulting in insufficient carbonization time during the carbonization process, resulting in a certain degree of raw material waste;

[0006] 2. Before the raw silk enters the carbonization furnace, it may be entangled and knotted, thus affecting the carbonization effect;

[0007] 3. After the carbonization of the raw silk is completed, static electricity is easily generated during the winding process, which creates certain safety hazards and has a certain impact on product quality. Summary of the invention

[0008] The purpose of the present invention is to provide a high-temperature carbonization device for carbon fiber production in order to solve the above-mentioned problems and overcome the defects of the prior art, as described in detail below.

[0009] To achieve the above object, the present invention provides the following technical solutions:

Multiple heaters are respectively located between the crests and troughs of the raw wire motion trajectory, so that the raw wire can maintain a distance from the heat source when moving, thereby maintaining a uniform and efficient heating effect. The winding roller reels the two traction ropes during the rotation process, and the two traction ropes slide along the corrugated groove in the furnace body during the winding process. During the sliding process, the two traction ropes drive one end of the raw wire to move rightward in the furnace body along the edge of the corrugated groove as the motion trajectory through the clamp. When one end of the raw wire contacts the winding roller, the winding roller reels the clamp and the raw wire together, and maintains traction to the right on the raw wire in the furnace body during the winding process.

Springs are arranged on the pull rings, and the two spring buckles are respectively in contact with the two elastic rods during movement. The pull rings themselves have a certain elastic force, so that the pull rings exert a certain pulling force on the elastic rods. When the spring buckle on the inner joint contacts the elastic rod during movement to the right, the elastic rod exerts pressure on the spring buckle through the pulling force of the pull ring, so that the spring buckle is disengaged from the buckle groove on the outer joint. At the same time, the elastic rod limits the inner joint, preventing the inner joint from moving to the right, thereby separating the inner joint from the outer joint.

[0014] Preferably, a combing device is provided on the base, and the combing device includes two No. 2 frames, both of which are installed on the base, and a sliding shaft is slidably installed on the inner wall of the No. 2 frame, and the bottoms of the two reels are respectively connected to rotating wheels, and the bottoms of the two rotating wheels are respectively hinged with connecting rods, and the two connecting rods are respectively hinged to the right ends of the two sliding shafts, and when the rotating wheel rotates, the sliding shaft is driven by the connecting rod to slide back and forth left and right on the No. 2 frame.

During the reciprocating movement of the combing plate, the plurality of comb teeth above the combing plate divide the raw silk into multiple bundles by continuously moving back and forth along the raw silk, and the multiple bundles of raw silk slide between multiple adjacent comb teeth respectively, so that the subsequent raw silk can enter the furnace body more neatly, avoiding the situation that the raw silk is messy and easy to get tangled before entering the furnace body, which has a certain impact on carbonization.

[0016] Preferably, a plurality of spring pieces are installed at the bottom of the combing plate, a tooth plate is installed between the two No. 2 frames, a plurality of teeth are arranged on the tooth plate, and the plurality of spring pieces are in contact with the teeth on the tooth plate during movement.

The staff adds the antistatic agent into the pressure box in advance, and the plurality of atomizing nozzles spray the antistatic agent on the carbonized raw silk below. The antistatic agent can reduce the generation of static electricity on the raw silk within a period of time.

[0019] The beneficial effects are:

[0020] 1. Through the cooperation of the traction device, furnace body, guide roller and heater, the staff can clamp one end of the raw silk on the clamp in advance before the carbonization operation begins. After multiple heaters are started, two traction ropes slowly pull one end of the raw silk toward the winding roller until one end of the raw silk passes through the interior of the furnace body, reducing the staff's operation steps. The raw silk moves to the right in a wavy motion trajectory according to the guidance of multiple guide rollers, which increases the motion trajectory of the raw silk, increases the heating time, and improves the space utilization rate inside the furnace body. In addition, one end of the raw silk can completely complete the entire heating process during the traction process, so that the entire section of the raw silk can be effectively carbonized to avoid material waste. Through the setting of two reels, after a carbonization operation is completed, the staff can rotate the two reels to make the two pull ropes drive the two traction ropes to reset. The operation steps are simple and easy to maintain.

[0021] 2. Through the arrangement of the combing device, the combing plate combs the raw silk by reciprocating movement left and right, so that the raw silk is divided into multiple bundles and slides into between multiple comb teeth. Before the subsequent raw silk enters the furnace body, it is first combed by the combing plate, so that the raw silk entering the furnace body is more neat and uniform, so that the raw silk is heated more evenly, and the probability of the raw silk being entangled and affecting the carbonization effect is reduced; through the cooperation of the spring piece and the tooth plate, when the combing plate combs the raw silk by reciprocating movement left and right, it can also vibrate the contacted raw silk more evenly through vibration, so that the raw silk is more evenly divided into multiple bundles and then slides into between multiple comb teeth, further improving the combing effect.

Through the action of the anti-static agent, the probability of static electricity generated on the surface of the raw silk is reduced, the influence of static electricity is reduced in subsequent processes, the safety hazard is reduced, and the product quality is guaranteed.

A traction device 3 is arranged on the base 1, and the traction device 3 includes two No. 1 frames 31, and the two No. 1 frames 31 are both installed on the base 1. Winding rollers 32 are rotatably installed on the two No. 1 frames 31, and a motor 33 is installed on one of the No. 1 frames 31. Two traction ropes 34 are connected to the winding roller 32, and a clamp 35 is installed between the two traction ropes 34. The end of the traction rope 34 away from the winding roller 32 is connected to an external joint 3 6, the two outer joints 36 are respectively connected with inner joints 37, and the inner joints 37 are connected with pull-back ropes 38. The outer walls of the front and rear sides of the furnace body 2 are respectively installed with reels 39, and the right outer wall of the furnace body 2 is installed with two elastic rods 310. The plurality of guide rollers 6 guide the raw silk. When the raw silk moves inside the furnace body 2, it slides along the edges of the plurality of guide rollers 6, so that the raw silk moves in the furnace body 2 in a wave-shaped motion trajectory, thereby increasing the distance that the raw silk moves inside the furnace body 2, thereby increasing the time that the raw silk stays in the furnace body 2. The plurality of heaters 7 are respectively located between the peaks and troughs of the raw silk motion trajectory, so that the raw silk can maintain a distance from the heat source when it moves, thereby maintaining a uniform and efficient heating effect. The winding roller 32 is in the process of rotating. The two traction ropes 34 are wound up, and the two traction ropes 34 slide along the corrugated grooves in the furnace body 2 during the winding process. During the sliding process, the two traction ropes 34 drive one end of the raw silk to move to the right in the furnace body 2 along the edge of the corrugated groove as the motion trajectory through the clamp 35. When one end of the raw silk contacts the winding roller 32, the winding roller 32 winds up the clamp 35 and the raw silk together, and maintains the traction force on the raw silk in the furnace body 2 to the right during the winding process. The output end of the motor 33 is connected to the winding roller 32, and the inner wall of the furnace body 2 is provided with two corrugated grooves. The two traction ropes 34 are respectively slidably connected with the two corrugated grooves. The clamp 35 includes two clamps, and the two clamps are connected by hinges. Switches are provided on the two clamps. The staff combs the raw silk and lays it flat on the guide On the plate 46, the clamp 35 is opened by the switch, one end of the original wire is placed between the two clamping plates, and the clamp 35 is closed. A spring buckle 371 is installed on the inner joint 37, and a buckle groove is provided on the outer joint 36. The pull-back rope 38 is wound on the reel 39, and a hand wheel is provided on the reel 39. When the pull-back rope 38 is pulled, the reel 39 is driven to rotate. The two reels 39 are rotated by the hand wheel. When the reel 39 rotates, the pull-back rope 38 located in the corrugated groove is reeled. During the reeling process, the pull-back rope 38 pulls the traction rope 34 to the left through the inner joint 37 and the outer joint 36, so that the two traction ropes 34 are reset. Two pull rings 311 are installed on the outer wall of the furnace body 2. The two pull rings 311 are respectively connected with the two elastic rods 310, and a spring is provided on the pull ring 311.The two spring buckles 371 contact the two elastic rods 310 respectively during the movement. The pull ring 311 itself has a certain elastic force, so that the pull ring 311 applies a certain pulling force to the elastic rod 310. When the spring buckle 371 on the inner joint 37 contacts the elastic rod 310 during the movement to the right, the elastic rod 310 applies pressure to the spring buckle 371 through the pulling force of the pull ring 311, so that the spring buckle 371 is disengaged from the buckle groove on the outer joint 36. At the same time, the elastic rod 310 limits the inner joint 37, preventing the inner joint 37 from moving to the right, thereby separating the inner joint 37 from the outer joint 36. Through the cooperation of the traction device 3, the furnace body 2, the guide roller 6 and the heater 7, the staff can clamp one end of the raw silk on the clamp 35 in advance before the carbonization operation begins. After the multiple heaters 7 are started, the two traction ropes 34 slowly pull one end of the raw silk toward the winding roller 32 until one end of the raw silk passes through the interior of the furnace body 2, reducing the staff's operation steps. The raw silk moves to the right in a wavy motion trajectory according to the guidance of the multiple guide rollers 6, so that the motion trajectory of the raw silk increases, the heating time increases, and the space utilization rate inside the furnace body 2 is improved. In addition, during the traction process, one end of the raw silk can completely complete the entire heating process, so that the entire section of the raw silk can be effectively carbonized, avoiding material waste. Through the setting of the two reels 39, after a carbonization operation is completed, the staff can rotate the two reels 39 to make the two pull ropes 38 drive the two traction ropes 34 to reset. The operation steps are simple and easy to maintain.

[0039] For further information, see Figure 9-10A combing device 4 is provided on the base 1, and the combing device 4 includes two No. 2 frames 41, and the two No. 2 frames 41 are both installed on the base 1. A sliding shaft 42 is slidably installed on the inner wall of the No. 2 frame 41, and the bottoms of the two reels 39 are respectively connected to rotating wheels 44, and the bottoms of the two rotating wheels 44 are respectively hinged with connecting rods 43, and the two connecting rods 43 are respectively hinged to the right ends of the two sliding shafts 42. When the rotating wheel 44 rotates, the sliding shaft 42 is driven by the connecting rod 43 to slide back and forth on the No. 2 frame 41, and the two sliding shafts 42 are respectively connected to connecting frames 45, and a guide plate 46 is installed between the two connecting frames 45, and a guide plate 46 is installed on the guide plate 46 through a spring. A combing plate 47 is provided with a plurality of comb teeth. When the two sliding shafts 42 slide back and forth left and right, they respectively drive the guide plate 46 to move back and forth left and right through the two connecting frames 45. The guide plate 46 drives the combing plate 47 to move synchronously through the spring. During the reciprocating movement of the combing plate 47 left and right, the plurality of comb teeth above it divide the raw silk into multiple bundles by continuously moving back and forth along the raw silk. The multiple bundles of raw silk slide between multiple adjacent comb teeth respectively, so that the subsequent raw silk can enter the furnace body 2 more neatly, avoiding the situation that the raw silk is messy and easy to be knotted before entering the furnace body 2, which has a certain impact on carbonization. By setting the combing device 4, the combing plate 47 combs the raw silk by reciprocating movement left and right, so that the raw silk is divided into multiple bundles and slides into between multiple comb teeth. Before the subsequent raw silk enters the furnace body 2, it is first combed by the combing plate 47, so that the raw silk entering the furnace body 2 is more neat and uniform, and the heating of the raw silk is more uniform, and the probability of the carbonization effect being affected by entanglement between the raw silk is reduced; through the cooperation of the spring piece 48 and the tooth plate 49, the combing plate 47 can comb the raw silk by reciprocating movement left and right, and can also vibrate the contacted raw silk more evenly through vibration, so that the raw silk is more evenly divided into multiple bundles and then slides into between multiple comb teeth, further improving the combing effect.

[0040] For further information, see Figure 11-Figure 12, a plurality of shrapnels 48 are installed at the bottom of the combing plate 47, a tooth plate 49 is installed between the two No. 2 frames 41, and a plurality of teeth are arranged on the tooth plate 49, and a plurality of shrapnels 48 contact the teeth on the tooth plate 49 during the movement, and an antistatic component 5 is arranged on the base 1, and the antistatic component 5 includes two mounting frames 51, and the two mounting frames 51 are respectively installed on the two No. 1 frames 31, and a pressure box 52 is installed between the two mounting frames 51, and a plurality of atomizing nozzles 55 are installed at the bottom of the pressure box 52, and the staff adds the antistatic agent into the pressure box 52 in advance, and the plurality of atomizing nozzles 55 are sprayed on the carbonized raw silk below, and the antistatic agent can reduce the generation of static electricity on the raw silk within a period of time. Through the setting of the antistatic component 5, the pressure box 52 sprays the antistatic agent on the raw silk that has been carbonized and left the furnace body 2 through the plurality of atomizing nozzles 55, and through the action of the antistatic agent, the probability of static electricity generated on the raw silk surface is reduced, and the influence of static electricity is reduced in the subsequent process, and the safety hazard is reduced, and the product quality is guaranteed.

[0041] With the above structure, the working principle of this case is that the staff combs the raw silk and lays it flat on the guide plate 46, opens the clamp 35 through the switch, places one end of the raw silk between the two clamps, closes the clamp 35, starts multiple heaters 7, the heater 7 heats the inside of the furnace body 2, the air duct 8 is connected to the external fan, and can discharge the exhaust gas generated in the carbonization process inside the furnace body 2 in time to avoid affecting the carbonization quality, starts the motor 33, and the motor 33 drives the winding roller 32 on the No. 1 frame 31 to rotate. The winding roller 32 reels the two traction ropes 34 during the rotation process. The two traction ropes 34 slide along the corrugated groove in the furnace body 2 during the winding process. The two traction ropes 34 drive one end of the raw silk through the clamp 35 during the sliding process. The end moves rightward in the furnace body 2 with the edge of the corrugated groove as the motion trajectory, and multiple guide rollers 6 guide the raw silk. When the raw silk moves inside the furnace body 2, it slides along the edges of the multiple guide rollers 6, so that the raw silk moves in the furnace body 2 with a wave-shaped motion trajectory, which increases the distance the raw silk moves inside the furnace body 2, thereby increasing the time the raw silk stays in the furnace body 2. Multiple heaters 7 are respectively located between the peaks and troughs of the raw silk motion trajectory, so that the raw silk can maintain a distance from the heat source when moving, thereby maintaining a uniform and efficient heating effect. When one end of the raw silk contacts the winding roller 32, the winding roller 32 winds up the clamp 35 and the raw silk together, and maintains the traction force on the raw silk in the furnace body 2 to the right during the winding process. When the traction rope 34 moves to the right, the traction rope 34 drives the inner joint 37 to move to the right through the outer joint 36, and the inner joint 37 drives the pull rope 38 to move to the right. When the pull rope 38 is pulled, the reel 39 is rotated. Since the pull ring 311 itself has a certain elastic force, the pull ring 311 applies a certain pulling force to the elastic rod 310. When the spring buckle 371 on the inner joint 37 contacts the elastic rod 310 during the rightward movement, the elastic rod 310 applies pressure to the spring buckle 371 through the pulling force of the pull ring 311, so that the spring buckle 371 is separated from the buckle groove on the outer joint 36. At the same time, the elastic rod 310 limits the inner joint 37, preventing the inner joint 37 from moving to the right, so that the inner joint 37 and the outer joint 36 separates, so that the two traction ropes 34 are out of contact with the furnace body 2. When the two traction ropes 34 are completely wound on the winding roller 32, the winding roller 32 continues to rotate to wind up the raw silk. When the carbonization of this batch of raw silk is completed, the staff transfers the raw silk on the winding roller 32 to the next process. At this time, the staff pulls out the two traction ropes 34 from the winding roller 32, plugs the two external joints 36 and the two internal joints 37 together again, and rotates the two reels 39 by the hand wheel. The reel 39 reels the return rope 38 located in the corrugated groove while rotating. During the winding process, the return rope 38 pulls the traction rope 34 to the left through the internal joint 37 and the external joint 36, so that the two traction ropes 34 are reset and prepared for the next operation in advance.Through the cooperation of the traction device 3, the furnace body 2, the guide roller 6 and the heater 7, the staff can clamp one end of the raw silk on the clamp 35 in advance before the carbonization operation begins. After the multiple heaters 7 are started, the two traction ropes 34 slowly pull one end of the raw silk toward the winding roller 32 until one end of the raw silk passes through the interior of the furnace body 2, reducing the staff's operating steps. The raw silk moves to the right in a wavy motion trajectory according to the guidance of the multiple guide rollers 6, so that the motion trajectory of the raw silk increases, the heating time is increased, and the space utilization rate inside the furnace body 2 is improved. In addition, during the traction process, one end of the raw silk can completely complete the entire heating process, so that the entire section of the raw silk can be effectively carbonized to avoid material waste. Through the setting of the two reels 39, after a carbonization operation is completed, the staff can rotate the two reels 39 to make the two pull ropes 38 drive the two traction ropes 34 to reset. The operating steps are simple and easy to maintain.

[0042] When the two reels 39 rotate, the two reels 39 respectively drive the two rotating wheels 44 to rotate. When the rotating wheels 44 rotate, they drive the sliding shaft 42 to slide back and forth on the second frame 41 through the connecting rod 43. When the two sliding shafts 42 slide back and forth, they respectively drive the guide plate 46 to move back and forth left and right through the two connecting frames 45. The guide plate 46 drives the combing plate 47 to move synchronously through the spring. In the process of the combing plate 47 moving back and forth left and right, the multiple comb teeth above it divide the raw silk into multiple bundles by continuously moving back and forth along the raw silk. The multiple bundles of raw silk slide into between multiple adjacent comb teeth respectively, so that the subsequent raw silk can enter the furnace body 2 more neatly, avoiding the situation that the raw silk is messy before entering the furnace body 2 and is easy to be knotted, which has a certain impact on carbonization. When the combing plate 47 moves, the combing plate 47 drives the multiple spring pieces 48 below it to move synchronously. When moving, each spring piece 48 continuously contacts with a plurality of teeth on the tooth plate 49, so that the multiple spring pieces 48 continuously vibrate, and the multiple spring pieces 48 transmit the vibration to the combing plate 47. Through the setting of the combing device 4, the combing plate 47 combs the raw silk by reciprocating left and right, so that the raw silk is divided into multiple bundles and slides into between multiple comb teeth. Before the subsequent raw silk enters the furnace body 2, it is first combed by the combing plate 47, so that the raw silk entering the furnace body 2 is more neat and uniform, so that the raw silk is heated more evenly, and the probability of the carbonization effect being affected by entanglement between the raw silk is reduced; through the cooperation of the spring piece 48 and the tooth plate 49, when the combing plate 47 combs the raw silk by reciprocating left and right movement, it can also vibrate the contacted raw silk more evenly, so that the raw silk is more evenly divided into multiple bundles and then slides into between multiple comb teeth, further improving the combing effect.

[0043] The staff adds the antistatic agent into the pressure box 52 in advance, and the winding roller 32 drives the multiple protrusions 56 to perform circular motion when rotating. The multiple protrusions 56 will contact and squeeze the two air cylinders 53 on the two mounting frames 51 when moving. After being squeezed, the two air cylinders 53 inject air into the pressure box 52 through two air pipes 54. The pressure box 52 uses the positive pressure to spray the antistatic agent inside it through multiple atomizing nozzles 55 on the carbonized raw silk below. The antistatic agent can reduce the generation of static electricity on the raw silk within a period of time. Through the setting of the antistatic component 5, the pressure box 52 sprays the antistatic agent on the raw silk that has been carbonized and leaves the furnace body 2 through multiple atomizing nozzles 55. Through the action of the antistatic agent, the probability of static electricity generated on the surface of the raw silk is reduced, the influence of static electricity is reduced in subsequent processes, the safety hazard is reduced, and the product quality is guaranteed.

[0044] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
