Description

Technical Field

[0001] This application relates to carbon fiber washing and drying technology, and more particularly to a carbon fiber drying apparatus. Background Technology

[0002] In the production and processing of carbon fiber filaments, the carbon fiber filaments after high-temperature carbonization need to undergo surface treatment. The carbonized carbon fiber filaments are washed with water to remove the dirt and impurities generated during the carbonization process, and then dried in preparation for the subsequent adhesive coating process.

[0003] Existing carbon fiber drying equipment uses hot roller dryers. Washed carbon fiber filaments are wound onto heated rollers in the hot roller dryer, and the filaments are dried as the heated rollers rotate and convey them. In existing hot roller dryers, the heated rollers used to convey and dry the carbon fiber filaments are located externally. The heat generated during drying is quickly dissipated, resulting in high energy consumption and low drying efficiency. Utility Model Content

[0004] This application provides a carbon fiber drying device to solve the problems of high energy consumption and low drying efficiency caused by the exposed heating rollers in existing carbon fiber drying devices.

[0005] This application provides a carbon fiber drying device, including a base plate, with a vertical plate fixed to the upper end of the base plate. A heating roller and a guide roller are rotatably connected to one side of the vertical plate, and a motor for driving the heating roller is installed on the other side. A cover with a gap is fitted onto the heating roller. An opening for the carbon fiber filament to enter and exit is provided at the lower end of the cover. Limiting rollers are rotatably connected to the two side walls of the opening. The guide roller is located below the opening and is used to guide the carbon fiber filament into the cover through the opening.

[0006] Optionally, an absorption tank containing absorbent liquid is fixed on the base plate, and an air pump is installed on the absorption tank. The air inlet pipe of the air pump is connected to the inside of the cover, and the exhaust pipe of the air pump extends downward into the absorbent liquid in the absorption tank. The upper end of the absorption tank is provided with an exhaust pipe for discharging filtered gas.

[0007] Optionally, a filter layer is fixed inside the absorption box, and the filter layer is located between the discharge pipe and the absorption liquid.

[0008] Optionally, the upper part of the cover is a cover body spliced ​​with it, and a slide rail is vertically fixed on the upright plate above the cover body. The cover body is slidably connected to the slide rail and can be opened upwards.

[0009] Optionally, the cover may be made of a transparent material.

[0010] Compared with the prior art, the advantages of the carbon fiber drying device provided in this application are:

[0011] By sleeving the cover on the heating roller, heat loss of the heating roller can be effectively reduced, and a heat preservation cavity is formed in the cover, thereby reducing the energy consumption required when the heating roller is running. Moreover, by limiting the carbon fiber yarn entering the cover through the limiting roller, the carbon fiber yarn entering the cover can be more closely attached to the heating roller, so that the carbon fiber yarn has a larger contact drying area, thereby improving the drying efficiency.

[0021] In use, the carbon fiber filament 16 enters from the opening at the lower end of the cover 6 through the guide roller 5, and the entering carbon fiber filament 16 is guided out of the cover 6 through the opening at the lower end of the cover 6 after winding around the heating roller 3 from the upper end. The limiting roller 7 guides the carbon fiber filament 16 entering and exiting the cover 6. The carbon fiber filament 16 sequentially passes through a plurality of covers 6 and winds around the heating roller 3. The motor 4 drives the heating roller 3 to rotate, thereby conveying and drying the carbon fiber filament 16.

[0022] In the embodiment, the cover 6 sleeved on the heating roller 3 can effectively reduce the heat loss of the heating roller 3, form a heat preservation cavity in the cover 6, and reduce the energy consumption required when the heating roller 3 operates. Moreover, the limiting roller 7 limits the carbon fiber filament 16 entering the cover 6, so that the carbon fiber filament 16 entering the cover 6 is more closely attached to the heating roller 3, the carbon fiber filament 16 has a larger contact drying area, and the drying efficiency is improved.

[0025] In a possible implementation, a filter layer 12 is fixed in the absorption tank 8, and the filter layer 12 is located between the discharge pipe 13 and the absorption liquid.

[0026] The gas not completely absorbed by the absorption liquid escapes upward from the liquid surface and is adsorbed and filtered by the filter layer 12. Activated carbon or molecular sieve can be arranged in the filter layer 12 to further adsorb and filter the waste gas.
