Spinning coagulating bath device

Abstract

The invention discloses a spinning coagulating bath device, and belongs to the technical field of textile machinery. The spinning coagulating bath device comprises a water tank (1), a water diversion partition plate (8) and a bundling godet assembly (6), wherein the water diversion partition plate (8) is arranged in the water tank (1), so that a containing space in the water tank (1) is divided into a first containing space (17) and a second containing space (14) by the water diversion partition plate (8); the bundling godet assembly (6) is arranged in the first containing space (17); a first through hole (18) is formed in the bottom of the second containing space (14), and the second containing space (14) communicates with the outside through the first through hole (18); and the height of the water diversion partition plate (8) is smaller than the top edge of the water tank (1). According to the spinning coagulating bath device, stable fluid in a coagulating bath body can be guaranteed, and in addition, due to the arrangement of the water diversion partition plate (8), it is guaranteed that the water tank (1) can be completely filled with solvent, and the gap requirement of cooling side blowing is met.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a spinning coagulation bath device. Background technique [0002] Dry-jet wet spinning is both dry and wet spinning, which means that after the spinning liquid is sprayed out through the spinneret micropores, it first passes through a dry layer, that is, the air layer, where physical changes occur, and the water in the spinning liquid evaporates rapidly. Dense, uniform, and thin filaments are formed, and then pass through the coagulation bath, and the filaments are solidified into a filament structure with high density, smooth surface and no grooves through the two-way diffusion and phase separation process of solvent and water. At present, dry-jet wet spinning has been widely used in the production of various fibers and can achieve high-speed spinning. In order to pursue high fiber production, producers often want to increase the speed of tow entering the coagulation ...

AI Technical Summary

Problems solved by technology

[0003] The coagulation bath tank in the existing production cannot be completely filled with solvent, resulting in too large blowing gap between the solvent liquid level and the spinneret, affecting the forming of the tow, and finally affecting the quality of the finished tow; In the bath water tank, in the actual production, due to the deep godet roller depth, it is difficult for workers to spin the tow; After falling into the coagulation bath, the tow cannot return to the tow with the water flow. The surface friction of the cluster godet roller made of stainless steel is relatively large, and the tension, tension and resistance of the final tow are relatively large, which makes it difficult for workers to form a tow.
