Abstract
A kind of path producing spandex fiber, comprise the first cylindrical shell that cross section is rectangle, be arranged on the second cylindrical shell of the outer larger length of side of the first cylindrical shell, close the first end cap, second end cap of the first cylindrical shell and the second cylindrical shell, unlike the prior art: the first cylindrical shell goes along with sb. to guard him into path, be vacuum in the cavity that the first cylindrical shell, the second cylindrical shell, the first end cap and the second end cap are formed.Compared with prior art, the thickness of heat-insulation layer can be reduced, and high insulating effect, energy-conservation, and solve heat exchange problem of non-uniform, safe and reliable, convenient construction is installed, and greatly reduces costs.
Description
Technical field
The utility model relates to the manufacturing equipment technology of spandex, is specially a kind of path producing spandex fiber.
Technical background
Dry spinning produces the dominating process route of spandex, and spinning shaft is one of key equipment in dry spinning fiber forming process, is the key equipment of constraints on fiber quality.For ensureing the volatilization that solvent is abundant and suitable, ensureing the quality of spandex fiber, the path insulation and hot air circulation scheme that are rationally suitable for must be adopted.
The spinning shaft of prior art for insulation and hot air circulation process normally: alumina silicate/calcium silicates/rock wool fibers layer in the outer cladding of path, arranges heating adjoining pipe that conduction oil circulates at path outer wall and applies one deck heat-conducting daub and guarantee hot air circulation in path; Its shortcoming is that conventional insulation material thermal conductivity factor is bigger than normal, and especially when high temperature, thermal conductivity factor rises very fast, and reach the heat-insulation layer that certain insulating power needs thicker, workload is corresponding also comparatively large, and effect is good not sometimes; Heat transfer is slow, and heat losses rate is high, and need constantly to the heat conduction adjoining pipe additional heat of spinning shaft, energy consumption is larger; And the heating agent relating to heat conduction adjoining pipe strengthens hot air circulation scheme, there is problem when constructing and run, smear the uneven heat that can affect as heat-conducting daub and distribute, and the heating agent of hot operation being also a potential safety hazard.
The spinning shaft of more existing patent Introduction dry spinning spandexs, if application number is the corridor for spinning of urethane elastic fiber of 200920200654.3, the cross section in its path is square, is provided with the square cannula of the larger length of side outside path, defines four sides sandwich type structure.In the interlayer of front and back, be respectively provided with 3-5 root heating tube, in the interlayer of left and right, be respectively provided with 4-6 root heating tube.Be welded with the fin of spiral winding outside heating tube, the circulating heat conduction oil of 280 ~ 300 DEG C provided by heat conducting oil boiler is provided in heat pipe, but its sleeve outer wrapping heat-insulation layer, still inevitably produce larger heat losses, energy consumption is still larger.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model solves in prior art that the insulation cost existed is high and heat insulation effect is not good enough, heat problem pockety in path.For realizing this object, technical solution adopted in the utility model is:
A kind of path producing spandex fiber, comprise the first cylindrical shell 2 that cross section is rectangle, be arranged on the second cylindrical shell 3 of the outer larger length of side of the first cylindrical shell 2, close the first end cap 5, second end cap 6 of the first cylindrical shell 2 and the second cylindrical shell 3, unlike the prior art: it is vacuum that the first cylindrical shell 2 is gone along with sb. to guard him in cavity that path 1, first cylindrical shell 2, second cylindrical shell 3, first end cap 5 and the second end cap 6 formed.
Further, the outer wall of the first cylindrical shell 2 lays reflecting layer 4.
Further, the inwall of the second cylindrical shell 3 lays reflecting layer 4.
Further, described reflecting layer is aluminium coated or silver coating.
Owing to have employed technique scheme, compared with prior art, the present invention has the following advantages:
The vacuum interlayer insulation in path makes thermal loss reduce, and can reduce the thickness of heat-insulation layer, and high insulating effect.
Without the need to laying heat conduction adjoining pipe and clay at path outer wall, continuing heat supply without the need to heating agent, only just can satisfy condition by the hot air circulation heat exchange in path, saving energy 35%.
Heat by reflecting layer radiation cycle, is evenly distributed in vacuum interlayer, solves due to the heat exchange problem of non-uniform that the circulation of heat conduction adjoining pipe is not smooth or construction wrong causes.
Safe and reliable, solve the potential safety hazard that the leakage because using high temperature heating agent to exist causes.
Reduce insulation layer thickness, do not use heat conduction adjoining pipe and heat-conducting daub, convenient construction is installed, and greatly reduces costs.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.Specific embodiment just in order to clearly demonstrate path of the present invention vacuum heat-preserving system composition and structure further, does not form limiting to the claimed invention.
The cross section in the path 1 of the utility model design is square, the first cylindrical shell 2 being rectangle by cross section is gone along with sb. to guard him and is formed, outer the second cylindrical shell 3 that the larger length of side is set of first cylindrical shell 2, first cylindrical shell 2 and the second cylindrical shell 3 are closed by the first end cap 5, second end cap 6 that shape is corresponding to the section of the chuck between the first cylindrical shell 2 and the second cylindrical shell 3, first cylindrical shell 2, second cylindrical shell 3, first end cap 5 and the second end cap 6 define four sides sandwich-type cavity body structure, and material is corrosion resistant plate.Is vacuumized by reserved pore in cavity, vacuum interlayer is interior without the need to arranging heating tube, and the inwall that the outer wall of the first cylindrical shell 2 lays reflecting layer 4, second cylindrical shell 3 also lays reflecting layer 4, and reflecting layer is that aluminium coated (may also be silver coating) is to reduce heat loss through radiation.
Model machine practice of trial production shows, the utility model realizes the stronger adiabatic heat insulating effect of corridor for spinning of urethane elastic fiber by the superior thermal insulation ability of split type vacuum structure, and heat in path is uniformly distributed by hot air circulation, is applicable to polyurethane fiber dry spinning.
