A kind of outer shroud is blown with flow regulating barrels, including cylindric inner side silk screen, the outside silk screen being set-located, in addition to two
Bracing ring, the bracing ring is arranged between inner side silk screen and outside silk screen, so that the inner side silk screen and the outside silk screen
It is arranged at intervals, two bracing rings are located at the axial both ends of flow regulating barrels respectively；
The expanded metal lath of cylindrical shape, the expanded metal lath axial direction two are also arranged between the inner side silk screen and the outside silk screen
End offsets with the bracing ring；
Also include sealing gasket, the sealing gasket is arranged on the axial both ends of flow regulating barrels, with sealing inner side silk screen, bracing ring,
The fit clearance of outside silk screen；
Cladding is provided with nonwoven layer on the lateral surface of the outside silk screen.
As the further improved technical scheme of the utility model, the inner side silk screen is made for 3 layers of volume circle of silk screen of 80 mesh
Into.
As the further improved technical scheme of the utility model, the outside silk screen is made for 4 layers of volume circle of silk screen of 60 mesh
Into.
As the further improved technical scheme of the utility model, the spacer of the inner side silk screen and the outside silk screen
From for 10 millimeters.
As the further improved technical scheme of the utility model, the nonwoven layer is made by the non-woven fabrics of 80 mesh.
It is of the present utility model to have technical effect that relative to prior art：
The utility model manufacturing cost simple in construction is low, meanwhile, using spaced inner side silk screen and outside silk screen and
Nonwoven layer is provided with the net in filum laterale, and there is the advantages of uniform of drying, can improve spinning quality.
Brief description of the drawings
Fig. 1 is the use state diagram that a kind of outer shroud blows with flow regulating barrels in the utility model embodiment；
Fig. 2 is the partial enlargement structural representation at A in Fig. 1.
Embodiment
The utility model is described in detail below with reference to embodiment shown in the drawings.But these embodiment party
Formula is not intended to limit the utility model, structure that one of ordinary skill in the art is made according to these embodiments, method or
Conversion functionally is all contained in the scope of protection of the utility model.
A kind of embodiment of the present utility model presented below：
Fig. 1 to 2 is referred to, a kind of outer shroud is blown with silk screen 1, outside on the inside of flow regulating barrels, including the cylindrical shape being set-located
Silk screen 2, in addition to two bracing rings 3, the bracing ring 3 are arranged between inner side silk screen 1 and outside silk screen 2, so that in described
Lateral filament net 1 and the outside silk screen 2 are arranged at intervals, and two bracing rings 3 are located at the axial both ends of flow regulating barrels respectively；
The expanded metal lath 4 of cylindrical shape, the axle of expanded metal lath 4 are also arranged between the inner side silk screen 1 and the outside silk screen 2
Offseted to both ends with the bracing ring 3；
Also include sealing gasket 5, the sealing gasket 5 is arranged on the axial both ends of flow regulating barrels, with sealing inner side silk screen 1, support
Circle 3, the fit clearance of outside silk screen 2；
Cladding is provided with nonwoven layer 6 on the lateral surface of the outside silk screen 2.
It should be noted that in melt spinning production process, melt is sprayed into being cooled in flow regulating barrels by spinneret 7
Tow 8.Arrow show cooling airflow and moves direction in Fig. 1.
Expanded metal lath 4 is arranged between inner side silk screen 1 and outside silk screen 2, it is therefore intended that the skeleton as whole flow regulating barrels.
Inner side silk screen 1 and outside silk screen 2 are arranged at intervals, and the first purpose is to make cooling wind energy enough according to side in good order
Blown out to from inner side silk screen 1, make to blow cooling wind on tow 8 in a circumferential direction more uniformly, another object is to make cold
But general mood stream more smoothes out stabilization, and tow 8, which is less prone to, to be rocked and situations such as silk.
It is miscellaneous in the outer cladding of filum laterale net 2 setting nonwoven layer 6, fine particle of the first purpose in wind is cooled down in filtering
Matter, while absorb certain moisture, the second purpose is to play a part of rectification and voltage stabilizing so that enters inner side silk screen 1 and outer
Air quantity is more uniform in a circumferential direction for cooling wind between lateral filament net 2.
It is test data of the present utility model below：
4 sampled points are respectively taken at axial upper, middle and lower three in flow regulating barrels, and (4 sampled points are circumferentially-spaced uniformly in circle
Set, namely 90 degree of interval is set), 12 sampled points altogether, measure the air-out wind speed of flow regulating barrels.
As can be seen from the above table, at any one place in upper, middle and lower, air-out wind speed circumference to worst error be far smaller than
The 0.1m/s of conventional criteria.It can be seen that air-out uniformity, the stability of flow regulating barrels are preferable.
Further, the inner side silk screen 1 is made up of 3 layers of volume circle of silk screen of 80 mesh.
Further, the outside silk screen 2 is made up of 4 layers of volume circle of silk screen of 60 mesh.
Further, the spacing distance of the inner side silk screen 1 and the outside silk screen 2 is 10 millimeters.
Further, the nonwoven layer 6 is made by the non-woven fabrics of 80 mesh.
It is of the present utility model to have technical effect that relative to prior art：
The utility model manufacturing cost simple in construction is low, meanwhile, using spaced inner side silk screen 1 and outside silk screen 2
And nonwoven layer 6 is provided with filum laterale net 2, there is the advantages of uniform of drying, spinning quality can be improved.
Finally it should be noted that：Embodiment of above is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the utility model is described in detail with reference to aforementioned embodiments, one of ordinary skill in the art should
Understand：It can still modify to the technical scheme described in foregoing each embodiment, or special to which part technology
Sign carries out equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from each reality of the utility model
Apply the spirit and scope of mode technical scheme.
