Problems solved by technology

[0003] The purpose of the present invention is to provide a type of tube-type thickening equipment. Through the tubular equipment, the thickening particles can be evenly heated and fully reacted in a small space to achieve the purpose of thickening, so as to solve the problem of thickening in the prior art. Slow speed or uneven viscosity increase, resulting in large particle damage and high ash content, making subsequent polymer spinning difficult technical problems

Abstract

The invention discloses a novel tubular thickening equipment. The tubular thickening equipment includes a thickening kettle; inside the thickening kettle, there are several charging bins, and the charging bins are straight pipelines; on the outer wall of the charging bin, there are several The heating channel is used to place the heat conduction wire or heat conduction oil. In the present invention, by setting distributed charging bins, the polymer melt can be fully and evenly heated in the loading bins at all levels, and the cross-sectional temperature of each part is basically the same, thereby ensuring the viscosity increase of the polymer in the device The process is basically the same. The thickening device of the present invention is not only suitable for thickening polyamide, but also suitable for other polymers. The design of the feeding bin of the novel tubular thickening equipment of the invention is reasonable, so that the polymer melt is heated evenly, the thickening process is stable, the thickening time is saved by more than 20-40%, and the viscosity uniformity error is within 5%.

Description

Technical field [0001] The present invention relates to a new tubular tacking device, belonging to the field of chemical fiber equipment. Background [0002] Solid phase tack increase, also known as solid phase polycondensation, the process of viscosity polymerization in the solid state of the polymerization reaction, thereby improving the molecular weight. This method aims to improve the spinability of spinning polymers. At present, the tacking equipment mostly uses the drum method, which has problems such as uneven heating, large particle damage, and more ash, resulting in long tacking time and uneven viscosity, resulting in problems such as uneven subsequent spinning. Therefore, a new tacking device needs to be provided. Contents of the Invention [0003] Object of the present invention is to provide a type of tubular tack-type tack-type equipment, through the tubular apparatus, so that the tackifying particles in a small space to obtain a uniform heat, sufficient reaction, t...
