Description
Technical field
The present invention relates to a kind of spinning equipment of textile industry, particularly relate to one and utilize the steam-heated dismantled and assembled spinning manifold of biphenyl heating agent.
Background technology
Spinning manifold, as the key equipment of chemical fibre melt spinning, can be divided into three parts by its structure by function.First part forms the mass transport of spinning manifold, metering, distribution and filtration, fiberizing system primarily of melt distribution circuit, filament spinning component conjunction, filament spinning component after melt distribution circuit, Spinning pumps, Spinning pumps conjunction, pump before pump etc.; The second part is for Part I provides the biphenyl steam heating agent room of heat energy; Part III is the insulation construction of spinning manifold.
When producing carbon black type conductive fiber etc. and containing the fiber product of carbon black, because the carbon black be dispersed in matrix polymer has the characteristic of reunion, sedimentation in extruding course of conveying, the normal situation that blocking melt pipeline occurs in spinning, for this reason, need often to clear up the melt distribution line before Spinning pumps in spinning manifold and after pump.
But because traditional spinning manifold is a kind of overall structure, biphenyl steam heating agent room adopts tilting pipe joint to weld with external heating agent steam supply pipeline, the insulation of spinning manifold adopts integral coating formula project organization.Therefore, to when clearing up in spinning manifold, need the heat-insulation layer first removing casing, cut off biphenyl pipeline, whole casing is carried out integral demounting.Then, when the blocking of clearing up inner melt pipeline needs to the spinning manifold disassembled, can only adopt and first cut spinning manifold, then the method that the melt pipe cutting blocked inside is changed.Whole cleaning process operation easier is large, and the processing time is long, need carry out mechanical process and welding, and due to the workload that reparation degree is poor, reinstall also large, so be applicable to the fiber product that production carbon black type conductive fiber etc. contains carbon black.
For this reason, a lot of people has proposed some solution to this problem.
