Moisture removal device for chemical fiber spinning raw material

Abstract

The invention discloses a moisture removal device for a chemical fiber spinning raw material. The device comprises a threaded rod extruder, a porous screen mesh, a moisture volatilization material cylinder, a spinning pump and a spraying mold, the porous screen mesh is located at an outlet of the threaded rod extruder, and the moisture volatilization material cylinder is located below the porous screen mesh; the spinning pump is located below an outlet of the moisture volatilization material cylinder, the spraying mold is located below the spinning pump, the porous screen mesh is connected with the threaded rod extruder through a pipe, and the spinning pump is connected with the moisture volatilization material cylinder and the spraying mold through pipes separately. The moisture removal device for the chemical fiber spinning raw material has the advantages that a heat preservation material cylinder which can be heated is arranged below the threaded rod extruder, the heating temperature is controlled within 180-230 DEG C, the extruded chemical fiber spinning raw material can pass through screen holes and form a thin filament shape through the porous screen mesh, accordingly, the moisture of chemical fiber spinning in the falling process is sufficiently heated and volatilized, the raw material drying operation before production in the prior art does not need to be conducted, andaccordingly energy can be effectively saved and consumption can be effectively lowered.

Description

technical field [0001] The invention relates to chemical fiber spinning processing equipment, in particular to a moisture removal device for chemical fiber spinning raw materials. Background technique [0002] In the production process of chemical fiber spinning, it is generally required that the moisture content of raw materials should be controlled within two thousandths, otherwise defects such as broken filaments will be easily caused during the spinning process, which will seriously affect the genuine product rate. At present, factories generally use drying and drying raw materials and then use them in production. The drying time is generally more than 8 hours, which is not energy-saving, and the moisture cannot be controlled to the best. This method consumes high energy and has low processing efficiency. The processing equipment in the prior art usually adopts the process that the chemical fiber melt extruded by the screw directly enters the spinning pump through the p...

Problems solved by technology

[0002] In the production process of chemical fiber spinning, it is generally required that the moisture content of raw materials should be controlled within 2 / 1000. Otherwise, it is easy to cause defects such as broken filaments during the spinning process, which will seriously affect the quality rate. If the moisture control is not good, it may seriously cause production failure.

At present, factories generally use drying and drying raw materials and then use them in production. The drying time is generally more than 8 hours, which is not energy-saving, and the moisture cannot be controlled to the best.
