Problems solved by technology

[0003] The quality of carbon fiber depends largely on the raw silk. Drying and densification is an important process in the preparation of carbon fiber raw silk. However, the heat of the existing dryer densification equipment is mostly concentrated on the surface of the roller, and the tow travels on the surface during spinning. Only small drafts can be achieved in the dryer densification box

Abstract

The invention discloses a carbon fiber precursor spinning, drying and densifying device, and belongs to the field of carbon fiber precursor spinning equipment. The carbon fiber precursor spinning, drying and densifying device comprises a tank body, a circulating pipeline, a draught fan, a heater, a heating pipe, heating rollers, a connecting shaft and a steam spray device, wherein the steam spray device comprises steam main pipelines which are vertically arranged, steam spray pipes which are vertical to the steam main pipelines and spray nozzles which are connected with the steam spray pipes. According to the carbon fiber precursor spinning, drying and densifying device disclosed by the invention, tows are dried and densified, the effect is good, the efficiency is high, interior airflow is relatively uniform, stable temperature gradient change is formed, interference to carbon fiber tows is reduced, and the drying effect of the carbon fiber tows is increased; meanwhile, steam drafting can be carried out, and the tows are enabled to obtain larger drafting multiples during a walking process.

Description

technical field [0001] The invention relates to a carbon fiber precursor spinning drying and densification device, which belongs to the technical field of carbon fiber precursor spinning equipment. Background technique [0002] Carbon fiber is a high-strength, high-modulus fiber made of polyacrylonitrile (PAN) fiber, viscose fiber or pitch fiber, which is made by heating to remove all elements other than carbon. It has good chemical stability, high temperature resistance, corrosion resistance, friction resistance, fatigue resistance and other properties. It is an excellent structural material in the preparation of high-performance composite reinforced materials, so it is widely used in textiles, chemicals, machinery, aviation, construction. , sporting goods and other fields. [0003] The quality of carbon fiber depends largely on the raw silk. Drying and densification is an important process in the preparation of carbon fiber raw silk. However, the heat of the existing drye...
