Abstract
The utility model discloses 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.The outside of interior air duct of the present utility model has added guide layer, and air-flow is tilted to air duct 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.
Description
Technical field
the utility model 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 purpose of this utility model is to provide a kind of air duct assembly.
for achieving the above object, the technical solution adopted in the utility model 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 utility model compared with prior art has following advantages:
because the outside of interior air duct of the present utility model 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 utility model;
accompanying drawing 2 is cross-sectional schematic of the present utility model;
accompanying drawing 3 is the utility model enlarged diagram A.
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 utility model is 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 utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
