Description

Technical Field

[0001] The utility model relates to the technical field of carbon fiber spinning, in particular to a carbon fiber spinning component. Background Art

[0002] Carbon fiber is a high-strength and high-modulus fiber with a carbon content of more than 90%. Spinning is an important step in carbon fiber processing. The spinning process usually involves a polymerization section and a spinning section. The spinning section involves the process of converting polyacrylonitrile stock solution into raw silk.

[0003] Among them, there are two types of spinning technologies: dry-jet wet spinning and wet spinning. Dry-jet wet spinning means that after the spinning liquid is ejected through the spinneret, it first passes through a section of air layer and then enters the coagulation bath for double diffusion, phase separation and formation of filaments.

[0004] After searching, a Chinese patent (publication number: CN217438360U) discloses a carbon fiber precursor dry-jet wet-spinning spinneret device, including a spinneret assembly, a coagulation bath and a protective cover. The protective cover is installed on the spinneret assembly, and the opening of the protective cover is downward. The protective cover forms a semi-closed dry air layer for surrounding the silk thread in the upper area of ​​the space formed by the spinneret assembly and the coagulation bath, and the lower area of ​​the space formed between the spinneret assembly and the coagulation bath is a fully open dry air layer.

[0005] In the prior art, when a shielding structure is used to block the space, a single shielding cover is used, which makes it inconvenient to connect the nozzle assembly to the coagulation bath, and during spinning, the spinneret needs to be kept at a suitable temperature. Therefore, the utility model proposes a carbon fiber spinneret assembly. Utility Model Content
