Molten reaction device for chemical fiber manufacturing

Abstract

The invention discloses a melting reaction device for chemical fiber manufacturing, which comprises a melting barrel, a screw feeding barrel and a waste gas treatment device; a heating wire is embedded in the inner wall of the melting barrel; an inner stirring ring is arranged in the melting barrel; An outer stirring ring is provided outside the inner stirring ring; a bolt feeding cylinder is connected to the left side of the melting barrel; a raw material storage box is connected above the bolt feeding cylinder; a heating jacket is arranged outside the raw material storage box, and the heating jacket It communicates with the melting barrel through the waste gas pipe; the heating jacket is connected with the waste gas treatment device. The present invention is equipped with the inner stirring ring and the outer stirring ring with the opposite rotation direction to fully stir the high-viscosity molten reaction raw materials, so that the reaction can be carried out thoroughly and the reaction efficiency is improved; The heat in the generated exhaust gas is fully utilized, and the exhaust gas is treated before being discharged to protect the environment.

Description

technical field [0001] The invention relates to the chemical fiber field, in particular to a melting reaction device for chemical fiber manufacturing. Background technique [0002] Chemical fibers are fibers with textile properties that are made from natural polymer compounds or artificially synthesized polymer compounds through the processes of preparing spinning dope, spinning and post-treatment. Fiber length, thickness, whiteness, gloss and other properties can be adjusted during the production process. And they have the advantages of light resistance, wear resistance, easy washing and drying, no mildew, no moths and so on. Widely used in the manufacture of clothing fabrics, filter cloths, conveyor belts, hoses, ropes, fishing nets, electrical insulation wires, medical sutures, tire cords and parachutes, etc. Generally, polymer compounds can be made into solutions or melts, extruded from the pores of the spinneret, and then solidified to form fibers. [0003] In the pr...

AI Technical Summary

Problems solved by technology

[0003] In the process of preparing spinning dope, it is necessary to use a melting reaction device. A common melting reaction device is only provided with a separate stirring rod, which cannot make the spinning dope with a high viscosity fully mixed and reacted, and the reaction produces a large amount of high-temperature waste gas. , directly discharged, will pollute the air, and at the same time, the waste gas contains a lot of heat that has not been fully utilized, and lacks a device to control the feeding speed and feeding amount
