Description

Device for drying tows by using hot air Technical Field The utility model relates to the technical field of tow drying, in particular to a device for drying tows by using hot air. Background The tow undergoes a number of critical steps during the production process to ensure its quality and performance. Among them, desalted water cleaning is a crucial link. Desalted water, i.e., purified water from which most minerals and impurities are removed, is used to clean the tow to remove oil stains, dust and other impurities that may adhere to the surface of the tow during the production process, and during the desalted water cleaning process, the tow is in sufficient contact with desalted water to effectively clean the micropores and surfaces inside the tow, and the increase in water content of the tow has a direct effect on the subsequent processing of the tow, particularly the drying and sizing steps, due to the penetration and adhesion of water, and hot air drying is an indispensable step for controlling the water content of the tow to ensure its stability and quality during subsequent processing. The hot air drying accelerates evaporation of moisture inside and on the surface of the filament bundle by blowing high-temperature dried air to the filament bundle. The existing device for drying the tows by hot air has the defects that the whole hot air in the device is uniformly distributed, the multi-section drying design is lacked, the tows usually contain higher moisture in the initial stage of drying, and the hot air with higher temperature is needed to accelerate the evaporation of the moisture. However, as the drying process continues, the moisture content of the filament bundle gradually decreases, and if the high-temperature drying is continuously maintained, not only energy waste is caused, but also unnecessary damages to the texture and performance of the filament bundle may be caused, such as fiber embrittlement or shrinkage non-uniformity caused by excessive drying.
