Description

Technical Field

[0001] This application relates to water washing technology in carbon fiber production, and more particularly to a carbon fiber water washing device. Background Technology

[0002] Carbon fiber material is made from carbon fiber precursor through a process of pre-oxidation, low-temperature carbonization, high-temperature carbonization, and water washing and gluing. During the pre-oxidation and carbonization process, impurities and dirt will be generated on the carbon fiber filaments, and oil and dust will also adhere to them during transportation. Therefore, it is necessary to clean it before gluing.

[0003] Existing carbon fiber washing equipment involves guiding carbon fiber filaments into a water tank and immersing them in water, then using a rotating roller brush to wash them along the length of the filaments. However, the roller brush in existing carbon fiber washing equipment can only clean surface stains on the carbon fiber filaments, failing to remove impurities and dirt that have detached from the fibers, thus affecting the quality and lifespan of carbon fiber products. Utility Model Content

[0004] This application provides a carbon fiber washing device to solve the problem that existing carbon fiber washing devices are unable to clean impurities and dirt inside carbon fibers.

[0005] This application provides a carbon fiber washing device, including a water tank, with guide rollers rotatably connected to both ends of the water tank, and support rollers for conveying carbon fiber filaments rotatably connected to both ends of the water tank. A roller brush for clamping and cleaning the carbon fiber filaments is rotatably connected inside the water tank. The roller brush is driven by a motor. A support plate is provided between the two guide rollers. The side end of the support plate is fixed to the inner wall of the water tank by a spring. An ultrasonic generator is installed at the bottom of the support plate. Multiple partitions are vertically fixed on the top surface of the support plate, and an ultrasonic cleaning channel is formed between adjacent partitions.

[0006] Optionally, as each bundle of carbon fiber filaments passes through the ultrasonic cleaning channel, the bundle is in contact with a partition on one side of the ultrasonic cleaning channel.

[0007] Optionally, a fan is installed at the top of the water tank at one end of the carbon fiber filament output, and the fan blows air downwards along the carbon fiber filament.

[0008] Optionally, the bottom of the water tank is sloped, and a drain pipe is provided at the lowest point of the water tank along the slope, with a valve installed on the drain pipe.

[0009] The carbon fiber washing device provided by the application, when the carbon fiber yarn enters the water in the water tank from one end for cleaning, passes through the ultrasonic cleaning channel formed by the supporting plate and the partition plate, and the vibration in the channel is cleaned by the ultrasonic generator. The high-frequency vibration in the fiber inside the carbon fiber yarn can be generated by the ultrasonic cleaning, so that the impurities and dirt in the fiber inside the carbon fiber yarn are cleaned. After the stains on the surface of the carbon fiber yarn are brushed by the rolling brush, the water tank is output from the supporting roller at the other end. BRIEF DESCRIPTION OF DRAWINGS

[0017] In order to make the purpose, technical solutions and advantages of the embodiments of the application more clear, the technical solutions in the embodiments of the application will be clearly and completely described below. Obviously, the described embodiments are some embodiments of the application, not all embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor also belong to the protection scope of the application.

[0018] As Figures 1-4 ​As shown, one embodiment of this application provides a carbon fiber washing device, including a water tank 1. Guide rollers 3 are rotatably connected to both ends of the water tank 1. Support rollers 4 for conveying carbon fiber filaments 11 are rotatably connected to both ends of the water tank 1. A roller brush 2 for clamping and cleaning the carbon fiber filaments 11 is rotatably connected inside the water tank 1. The roller brush 2 is driven by a motor. A support plate 5 is provided between the two guide rollers 3. The side end of the support plate 5 is fixed to the inner wall of the water tank 1 by a spring 6. An ultrasonic generator 7 is installed at the bottom of the support plate 5. Multiple partitions 8 are vertically fixed on the top surface of the support plate 5, and an ultrasonic cleaning channel is formed between adjacent partitions 8.

[0019] In use, carbon fiber filaments 11 are conveyed to the water tank 1 by rollers 4 and pressed into the water by guide rollers 3. A motor drives a roller brush 2 to rotate along the length of the carbon fiber filaments 11, which is then washed during the conveying process. The carbon fiber filaments 11 that have entered the water pass through the ultrasonic cleaning channel between the partitions 8. The ultrasonic generator 7 generates vibrations in the ultrasonic cleaning channel through the support plate 5 and the partitions 8, which ultrasonically cleans the carbon fiber filaments 11 that have passed through it.

[0020] In this embodiment, when the carbon fiber filament 11 enters the water in the water tank 1 for cleaning from one end, it passes through the ultrasonic cleaning channel formed by the tray 5 and the partition 8. The ultrasonic generator 7 performs ultrasonic cleaning by vibrating the channel. Ultrasonic cleaning generates high-frequency vibrations inside the fibers of the carbon fiber filament 11, effectively cleaning impurities and dirt from within the fibers. After the roller brush 2 brushes away the dirt on the surface of the carbon fiber filament 11, it exits the water tank 1 from the other end through the roller 4.

[0021] In one possible implementation, each bundle of carbon fiber filament 11 is in contact with a partition 8 on one side of the ultrasonic cleaning channel as it passes through the ultrasonic cleaning channel.

[0022] The width of the tray 5 and the spacing of the partitions 8 are widened so that the carbon fiber filaments 11 can expand through the partitions 8 when passing through the ultrasonic cleaning channel. The increased spacing between the carbon fiber filaments 11 is conducive to the cleaning and removal of stains. Furthermore, during expansion, the carbon fiber filaments 11 can fit against the inner wall of the partitions 8, which is beneficial to the vibration transmission of ultrasonic cleaning.

[0023] In one possible implementation, a fan 9 is installed at the top of the water tank 1 at one end of the carbon fiber filament 11, and the fan 9 blows air downward along the carbon fiber filament 11.

[0024] When the cleaned carbon fiber filaments 11 are output from the water tank 1, the fan 9 blows air downwards along the carbon fiber filaments 11, which can blow off most of the water attached to the carbon fiber filaments 11, which is beneficial to improving the subsequent drying efficiency.

[0025] In one possible implementation, the bottom of the water tank 1 is a slope, and a drain pipe 10 is provided at the lowest point of the water tank 1 along the slope, with a valve installed on the drain pipe 10.

[0026] The bottom of the water tank 1 is sloped, which allows the detached carbon fiber powder and stains to slide and accumulate to one end during the sedimentation process. When the accumulation is too large, it is discharged from the drain pipe 10.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
