The utility model comprises an outer cylinder and an inner cylinder, wherein the upper part of the outer cylinder is in a cone shape, the lower part of the outer cylinder is in a cylinder shape, a middle rectifying layer in an annular plate shape with holes is arranged between the outer cylinder and the inner cylinder, and the top end at the upper part of the outer cylinder is connected with the upper end of a blowing drum; the lower end of the blowing drum is supported by a pallet that is sheathed on the inner cylinder, the wall of the blowing drum is provided with through holes and is sheathed with wire meshes inside, the wall of the lower part of the outer cylinder is provided with a hole and is in welded joint with an air inlet pipe via the hole, and the whole annular air blowing device is supported on a base plate. The utility model has the advantages that the air pressure of the cooling air is stable, the wind speed is uniform, and the damping value is low; the utility model can use cooling air of low air pressure, which reduces energy consumption.
Description
Technical field
The utility model relates in the chemical fibre manufacturing a kind of totally-enclosed annular blowing device on the apparatus for melt spinning, to the melt thread that just comes out from the spinnerets cooling of drying, makes it the solid-state tow of solidify out into when being used for spinning.
Background technology
Totally-enclosed annular blowing device is that melt spinning method is produced an important device in the chemical fibre equipment.Its cooling effect obviously is better than other annular blowing forms, and the uniformity of its blowing with become open type and the semi-open-type annular blowing of yarn quality before to have extremely significantly and improve.
Blowing drum in the totally-enclosed annular blowing device is its core.Existing annular blowing device has two kinds, and a kind of Blowing drum of half open form is made up of inside and outside two-layer damping material, is respectively porous circle and the nonwoven fabric that is coated on porous circle outside.Owing to two-layer nonwoven and two-layer porous circle are arranged, make the damping value of Blowing drum relatively large.And nonwoven fabric inconvenience is cleaned, and consumes greatly, and this also makes the cost of regular maintenance than higher; The Blowing drum of another kind of totally-enclosed annular blowing device then is made of sintering metal, and its damping value is higher, and required blast is quite high, and energy consumption is big especially.
Summary of the invention
The utility model is intended to design a kind of low blast, less cooling wind regime of energy consumption of adopting, and simple in structure, blowing uniformity is good, and cooling performance is superior, makes simple installation, and daily clean and maintenance is convenient, reduces the totally-enclosed annular blowing device of energy consumption.
The totally-enclosed annular blowing device of the utility model design comprises: urceolus and inner core, it is conical that urceolus top is, and cone angle is 45 °～65 °, and the urceolus bottom is cylindrical, be provided with the middle rectification layer of annular slab form with holes between urceolus and the inner core, the urceolus top is connected with the Blowing drum upper end.The lower end of described Blowing drum is then by the pallet support that is enclosed within on the inner core, and the barrel of Blowing drum has through hole and interior cover steel wire, perforate and be welded to connect on the barrel of urceolus bottom by this hole and blast pipe, and the full annular blowing device is bearing on the base plate.
The rectification element that middle rectification layer between urceolus and the inner core is first level is made of two annular slabs with holes.Annular slab has the eyelet that diameter is 2.5～8mm, its percent opening is that the ratio of summation and the area of annular slab of perforation hole area is 5%～40%, distance between two annular slabs is 35～60mm, and its effect is that the blast that ajutage is sent the cooling air that comes to is tentatively obtained balance before by described annular slab damping.Again reposefully up, wind turns to after arriving the urceolus top conical surface again, by radially blowing away to the center.In the process of blowing away to the center, cooling air is through Blowing drum, and barrel and steel wire by the Blowing drum perforate carry out again balance, rectification to cooling air, and filtering function is arranged.It is that the tiny through hole of 2～4mm becomes the porous circle that the Blowing drum barrel has diameter, and its percent opening is that the ratio of summation and the Blowing drum outer surface of perforation hole area is 10%～50%.
The utility model with the advantage that the structure of common inside and outside two rectification tubes (each all adopts the coated porous circle of nonwoven fabric) is compared is, though Blowing drum has only one deck porous circle and layer of steel wire net circle, but cooling air is because at the preceding centre rectification layer that passed through, the stability of its pressure and the degree of consistency are more than existing structure height, so the wind speed uniformity that Blowing drum is produced by boasting at sustained height is quite high.
The utility model device is not also owing to use nonwoven fabric, also do not use sintering metal, and used rectification, the filtration system that constitutes by the middle rectification layer of two annular slabs with holes and Blowing drum porous circle and steel wire, make the damping value in the whole system reduce, can use the cooling air of low blast, thereby significantly reduce the consumption of energy.
Description of drawings
Accompanying drawing 1 is the utility model cross-sectional view; Accompanying drawing 2 is the up and down curve synoptic diagram of the cold air blast velocity on each height aspect of Blowing drum, and this curve is that the vector end points with each aspect cold air blast velocity connects the result who forms.Among the figure: 1. urceolus top; 2. Blowing drum; 3. urceolus bottom; 4. middle rectification layer; 5. inner core; 6. base plate; 7. pallet; 8. blast pipe.
The specific embodiment
Below in conjunction with the description of drawings implementation process.
As shown in Figure 1, middle rectification layer 4 is the porous plate of annular, totally two, is installed between urceolus bottom 3 and the inner core 5.And fix by bracing ring.The material of porous plate is anticorrosive stainless steel, thickness is 1.5mm, have the hole that diameter is 5mm on the porous plate, its percent opening is 30%, urceolus top 1 is connected with urceolus bottom 3 usefulness bolts, the upper end of Blowing drum 2 is connected with bolt with 1 top, urceolus top, the lower end of Blowing drum 2 is connected with pallet 7, and there is a sealing gasket that it is not leaked out, the barrel of Blowing drum 2 also is the porous circle, is made by the anticorrosive stainless steel material that 1.5mm is thick, and has the through hole that diameter is 3mm, its percent opening is 40%, cover steel wire in the Blowing drum 2.After cooling air enters from blast pipe 8, before by middle rectification layer 4, obtain rough balance because the resistance of Blowing drum 2, the cooling air further balance of getting back, last cooling air by around radially blow away to the center, tow is cooled off.Tray sleeve is on inner core, and its effect is firmly to support Blowing drum.
