Abstract
The invention discloses a blowing tube assembly which comprises an outer blowing tube and an inner blowing tube, wherein the outer blowing tube is positioned on an outer layer, a plurality of through holes are formed in the outer blowing tube, the inner blowing tube is positioned on an inner layer and is composed of a plurality of layers of screen meshes, a gap is formed between the outer blowing tube and the inner blowing tube, a diversion layer is further arranged on the outer side of the inner blowing tube, and through holes which are inclined downward from outside to inside are uniformly distributed in the diversion layer. According to the blowing tube assembly, the diversion layer is additionally arranged on the outer side of the inner blowing tube, so as to guide airflows in an inclined mode downward into the inner blowing tube, so that the airflows which make into contact with polyester fiber in the blowing tube are stabilized downward, the airflows are smooth and stable, and the performance of the polyester fiber is improved.
Description
Technical field
the present invention relates to a kind of air duct assembly.
Background technology
current polyester fiber is all adopt polyester melt to spray fast from spinnerets under pressure, then under cooling wind action, silk is cooled to, cool rapidly through air duct of also drying from the polyester fiber of spinnerets ejection from the high temperature of 297 DEG C, make polyester fiber rapidly from molten condition cooled and solidified, become solid-state fiber, the process wherein cooled rapidly is particularly important, more even from the cooling air of air duct blowout, the polyester fiber performance produced is better, in addition, the air-flow of current air duct blowout is all horizontal direction, there is certain sinuous flow in the air-flow contacted with polyester fiber in air duct inside, thus tow is shaken, bar is done excessive, affect the quality of product, the cooling air duct that a kind of wind direction of current needs is stable.
Summary of the invention
the object of this invention is to provide one
for achieving the above object, the technical solution used in the present invention is: a kind of air duct assembly, comprise the air duct being positioned at the outer field outer air duct being distributed with multiple through hole and forming with the multi-layer silk screen being positioned at internal layer, gap is provided with between described outer air duct and described interior air duct, the outside of described interior air duct is also provided with guide layer, and described guide layer is evenly distributed with the through hole under being from outer to inner tilted to.
preferably, the tilt angles of described through hole is 45 °.
preferably, described through hole is hexagonal hole.
preferably, described guide layer is be wound into cylindric cellular board.
preferably, the multi-layer silk screen forming described interior air duct is steel wire.
because technique scheme is used, the present invention compared with prior art has following advantages:
because the outside of interior air duct of the present invention has added guide layer, air-flow is tilted to air duct in lower importing, the air-flow contacted with polyester fiber in air duct can have been made to be downwards stable, made air-flow steady, add polyester fiber performance.
Accompanying drawing explanation
accompanying drawing 1 is cross sectional representation of the present invention;
accompanying drawing 2 is cross-sectional schematic of the present invention;
accompanying drawing 3 is enlarged diagram A of the present invention.
in above accompanying drawing: 1, outer air duct; 2, interior air duct; 3, guide layer; 4, through hole.
Detailed description of the invention
below in conjunction with embodiment shown in the drawings, the invention will be further described:
embodiment one: shown in accompanying drawing 1-3.
a kind of air duct assembly, comprise the air duct 2 being positioned at the outer field outer air duct 1 being distributed with multiple through hole and forming with the multi-layer silk screen being positioned at internal layer, gap is provided with between outer air duct 1 and interior air duct 2, it is characterized in that: the outside of interior air duct 2 is also provided with guide layer 3, the through hole 4 under guide layer 3 is evenly distributed with and is from outer to inner tilted to.
the tilt angles of through hole 4 is 45 °.
through hole 4 is hexagonal hole.
guide layer 3 is for being wound into cylindric cellular board.
in composition, the multi-layer silk screen of air duct 2 is steel wire.
the outside of the interior air duct 2 of the present embodiment has added guide layer 3, air-flow is tilted to air duct 2 in lower importing, the air-flow contacted with polyester fiber in air duct can be made to be downwards stable, makes air-flow steady, adds polyester fiber performance.
above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
