Description
Technical field
The present invention relates to a kind of chemical fibre manufacturing fields, more particularly, to a kind of rectification of fiber cooling ring blowing apparatus
Cylinder and preparation method thereof.
Background technology
For the cooling procedure of chemical fibre melt spinning, especially staple fiber, independent outer-ring ventilation side is generally used
Method cools down tow, reaches to the cured effect of tow cooling.Now the flow regulating barrels that generally use with porous plate outsourcing without
Woven fabric or the mode of porous plate winding metal mesh improve the damping of flow regulating barrels, is dried under different technology conditions with this to meet
Uniformity.But since the dust containing capacity of non-woven fabrics or multiple layer metal net is limited, it must replace or clean to certain period, thus lead
The yield of cause declines and because of driving and parking because its product quality fluctuates.To subtract the replacement number of flow regulating barrels as far as possible, usually to carry
The filtering accuracy of high fresh air or return air is cost, causes the usage amount of filter bag to increase and increases with the energy consumption of wind turbine.
Invention content
In order to solve, prior art middle ring blowing device flow regulating barrels service life is short, flow regulating barrels intensity is low yielding etc. asks
Topic, it is an object of the present invention to provide a kind of flow regulating barrels of fiber cooling ring blowing apparatus, which reduces damping, drop
Low energy consumption, reduce production this, improve the spinning quality of staple fiber product.Another object of the present invention is to provide one kind
The production method of above-mentioned flow regulating barrels.
In order to realize the first above-mentioned purpose, present invention employs technical solutions below：
A kind of flow regulating barrels of fiber cooling ring blowing apparatus, which includes upper flange, lower flange and circular cylinder body structure
At circular cylinder body is fixed on upper flange and lower flange, and the circular cylinder body is made of n-layer cylinder, and n is more than 2
Positive integer, by being arranged concentrically, the cylinder is made of n-layer cylinder stainless steel porous plate, and the side wall of cylinder is provided with multiple lead to
Air holes, for the pore diameter range of ventilation hole in 1.0mm~4.5mm, percent opening is 15%~42%.
Preferably, the circular cylinder body is made of 3 ~ 5 layers of cylinder.
Preferably, the thickness of the stainless steel porous plate be 1mm~1.5mm, upper flange, lower flange thickness exist
3mm~4mm.
Preferably, the side wall of the cylinder is provided with the blind area of 2mm~3mm, blind area apart from upper flange and lower flange
Inside it is not provided with ventilation hole.It ensure that the needs of accurate blowing height and welding.
Preferably, the inside and outside two sides of the cylinder is handled through electrobrightening, more coarse one side as windward side,
Relatively smooth one side is as leeward.Its object is to reduce oligomer gathering on porous plate in spinning process and be convenient for
Accumulate in the cleaning of upper oligomer on the inside of flow regulating barrels.
Preferably, it is 0.5mm~1.5mm's that the upper flange, lower flange upper and lower corresponding, which are provided with the roads n-2 depth,
Annular groove, the upper and lower end of the outermost cylinder of the circular cylinder body outside with the outer edge of upper flange and lower flange respectively
Edge concordantly welds, the upper and lower end of the cylinder of the circular cylinder body innermost layer inward flange with the inward flange of upper flange and lower flange respectively
Concordant welding, the upper and lower end of the cylinder of n-2 is inserted into upper flange and the annular groove on lower flange and mutually welds respectively among circular cylinder body
It connects.
In order to realize the second above-mentioned purpose, present invention employs technical solutions below：
A kind of manufacturing method for the flow regulating barrels preparing above-mentioned ring blowing device, includes the following steps：
1）Stainless steel plate shearing machine is cut into strip, surrounding is reserved bigger 4mm~5mm than required size, using punching mechanical
Punching and the imperforate section of 5mm~6mm is reserved apart from lower edges, the stainless steel plate after punching is cut into institute on stainless steel
Size is needed, left and right side alignment argon arc welding or ion are welded into cylinder；
2）Multi-layer cylinder is sequentially placed into from the inside to surface in its lower flange with annular groove, then covers upper flange, pass through
After the flange groove of rotation upper flange for several times blocks cylinder, apply certain load while ensureing verticality, it later will most
Inner layer cylinder and outermost layer cylinder welding are to upper flange and lower flange.
The percent opening of the porous plate of flow regulating barrels of the present invention and aperture because the difference of its product can carry out different designs and
Arrangement.For porous plate connection gap using laser butt welding at cylinder, soldered width is no more than 0.2mm.Correspond to the interior of cylinder
Circle and outside diameter output the annulus that depth is 0.5mm~1.5mm on upper and lower mounting flange, then multi-layer cylinder and
A solid welding is carried out to the inner edge of flow regulating barrels and outer rim inner edge corresponding with flange and outside with argon arc welding after flange is connected good above and below
It is fixed.
The flow regulating barrels of flow regulating barrels that the present invention is closed with multi-layer porous board group substitution conventional belt metal mesh, reduce metal mesh with
The fastness of flange welding requires and the difficulty of woven wire connecting sewing weld seam.In addition.It is 1mm~1.5mm's by 4~5 layer thickness
More flow regulating barrels intensity that porous plate is combined are far above the intensity of conventional rectification cylinder, and there is no caused by flow regulating barrels insufficient strength
It deforms, irregular problem of drying.Simultaneously because the metal mesh without internal layer also reduces the high standard welding of metal mesh and flange
It is required that producing efficiency also greatly improves.The flow regulating barrels intensity of which processing is high, it is indeformable, without repair, be after enterprise has saved
The maintenance cost of phase, the most key is flow regulating barrels during use without needing to change, and saves manpower, improves yield, is improved
Product quality.
