Detachable spinning manifold heated by biphenyl steam which is heating medium

Abstract

The invention discloses a detachable spinning manifold heated by biphenyl steam which is a heating medium. The detachable spinning manifold comprises an upper manifold and a lower manifold. The detachable spinning manifold has the advantages that components such as metering pumps and melt pipelines which can be blocked easily are arranged in the upper manifold, a replaceable spinning assembly and a fixed heat-insulation structure are disposed in the lower manifold, the upper manifold and the lower manifold are respectively provided with biphenyl steam inlets and biphenyl condensate reflux inlets which are of straight pipe structures with loose flanges, and a detachable filled heat-insulation layer is arranged on the surface of the upper manifold, so that the upper manifold can be easily separated from a biphenyl steam circulating system or connected with the biphenyl steam circulating system and can be perpendicularly hoisted out or assembled; and the upper manifold and the lower manifold are connected into the same biphenyl steam generator by parallel biphenyl circulating pipelines, so that the temperature of the inside of the upper manifold and the temperature of the inside of the lower manifold keep uniform and consistent.

Description

technical field [0001] The invention relates to spinning equipment in the textile industry, in particular to a detachable spinning box heated by biphenyl heat medium steam. Background technique [0002] As the key equipment of chemical fiber melt spinning, the spinning box can be divided into three parts according to its structure and function. The first part is mainly composed of the melt distribution pipeline before the pump, the spinning pump, the spinning pump assembly, the melt distribution pipeline after the pump, the spinning assembly assembly, the spinning assembly, etc., which constitute the material delivery of the spinning box. , metering, distribution and filtration, and fiber-forming system; the second part is the biphenyl steam heat medium chamber that provides heat energy for the first part; the third part is the insulation structure of the spinning box. [0003] When producing carbon black-containing fiber products such as carbon black-type conductive fibers...

AI Technical Summary

Problems solved by technology

[0006] Chinese patent CN03220585.6 "Melt Spinning Spandex Detachable Spinning Box" discloses an up and down detachable spinning box, but because the volume of the upper and lower boxes is the same, the insulation material covers it evenly, and shares a biphenyl Pipeline, resulting in the workload is not reduced too much when dismantling

Due to this method, the melt distribution system is made into an assembly structure of several metal blocks, resulting in complex operations and high technical requirements during disassembly and installation.

In addition, the module in this patent is a block of stainless steel. Compared with the melt pipeline directly immersed in the spinning box filled with stable biphenyl vapor and heated, the stability and uniformity of the spinning temperature are poor
