Description

Technical Field

[0002] The spinning device refers to the equipment used to convert polymer solution or melt into fiber. It plays an important role in the production process of carbon fiber. In the production process of carbon fiber, the spinning device is usually used to convert carbon source polymers such as polyacrylonitrile into carbon fiber precursor through a specific process.

[0003] As disclosed in Chinese Patent Publication No. (CN213172712U), a carbon fiber wet spinning device includes a coagulation tank, in which a spinneret and a first traction roller are arranged in sequence along the traveling direction of the precursor, and at least three feed ports of the same size are opened on the spinneret, and each of the feed ports is connected to a precision metering pump. The advantage of this utility model is that the linear density fluctuation during the spinning process of the carbon fiber precursor is reduced.

[0004] However, as in the above patent, there is still a problem of poor filtering effect of the spinning liquid before spinning of the spinning device. The carbon fiber exists in the form of spinning liquid before spinning preparation, and is sprayed out and cooled through the spinneret to form fiber filaments. The purity of the spinning liquid determines the quality of the carbon fiber. Failure to perform efficient filtration will cause the spinning liquid to contain solid impurities, undissolved polymers, gels, etc., which will cause broken filaments or spinneret blockage in the subsequent spinning process.
