Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The present invention relates to a kind of bushing air-conditioner wind orifice plate, solve the problem that the air-out of bushing air-conditioner wind is uneven.Fig. 1 is the application scenarios schematic layout pattern of bushing air-conditioner wind orifice plate.As shown in Figure 1, bushing air-conditioner wind bellows 1 apportion is suspended on the both sides of bushing 3, and bushing 3 is placed in the centre of two bushing air-conditioner wind bellows 1.Glass fibre 7 forms regular glass fiber bundle after the integration of baster 4 and buncher 5, and glass fiber bundle extends in wire drawing machine 6.In the scene described by Fig. 1, bushing air-conditioner wind is used for cooled glass filament root, ensures the consecutive production of glass fiber precursor.
Fig. 2 is air-conditioner wind box structure schematic diagram.Air-conditioning inner bellows is cavity-like, is provided with bushing bellows controlled valve 8.Different according to the demand of nozzle plate temperature field, airflow field, bushing bellows controlled valve regulates air quantity, and then the wind speed of regulating orifice plate each region air outlet.In actual production, bushing air-conditioner wind bellows are connected with main air duct, and main air duct blows after the wind come enters bushing air-conditioner wind bellows and meets obstructions and can deflect and reflect, and causes bellows both sides (also claiming end) not identical with the wind speed at middle part.The structures shape of air outlet air output, arranges orifice plate at the air outlet place of bushing air-conditioner wind bellows, utilizes orifice plate water conservancy diversion air-conditioner wind.
Fig. 3 is traditional bushing air-conditioner wind orifice plate.Fig. 3 illustrates diameter and the arrangement mode of traditional orifice plate exhaust vent, traditional orifice plate has been covered with diameter equal, the circular exhaust vent of even density, namely adopts the orifice plate of equal diameter size to carry out water conservancy diversion.Obvious traditional approach wind speed lack of homogeneity, cannot blow out relatively more uniform wind.Fig. 4 is embodiment of the present invention modified bushing air-conditioner wind orifice plate.
As shown in Figure 4, a kind of bushing air-conditioner wind of bushing air-conditioner wind orifice plate orifice plate after the present invention improves is provided with the exhaust vent for regulating air-conditioner wind, orifice plate after improvement divides and has several subregions, here also referred to as wind district, several exhaust vents are set in each subregion, in order to play a guide functions, in each subregion, the aperture of exhaust vent and arrangement mode decide according to needing the air output of this subregion in actual production, air output=air holes area of section × wind speed.Here air output is a concept for set, refers to all exhaust vent unit interval Inner guide total air output out in a certain described subregion, i.e. the air quantity sum that goes out of each exhaust vent water conservancy diversion.An orifice plate is generally no less than 2 subregions.
Setting is the first subregion by the subregion of bellows end, and because the wind speed by bellows end is large, origin or beginning is little, larger without air quantity during exhaust vent water conservancy diversion; When therefore setting out air holes in the first subregion, the relatively short and small aperture in several apertures should be set.
Setting is the second subregion by the subregion in the middle part of bellows, and the wind in this subregion is not very large without air quantity during exhaust vent water conservancy diversion, should arrange the relatively larger macropore in several apertures when therefore setting out air holes in the second subregion.
Suppose with the first subregion for benchmark, first use wind measuring device (can be air output measuring barrel for air outlets) to measure the air quantity of the bushing air-conditioner wind that the first subregion from orifice plate is produced by boasting, this air quantity is recorded; And then measure the air quantity of the bushing air-conditioner wind that the second subregion from orifice plate is produced by boasting, this air quantity is recorded, adjust the exhaust vent quantity in the second subregion and arrangement mode, until the air output of the second subregion is identical with the air output of the first subregion, even if the first subregion and the second subregion air output slightly difference, error also should in the scope of producing permission.Profit in this way, just can regulate the guiding of bushing air-conditioner wind, obtains uniform air-conditioner wind.
Orifice plate in Fig. 4 divides and has four subregions, the structure at this division and bushing bellows air outlet place has relation.The one side that air quantity is large, respective apertures, the corresponding macropore of the one side that air quantity is little.Fig. 5 is embodiment of the present invention bushing air-conditioner wind orifice plate assembling schematic diagram.Composition graphs 1 and Fig. 5, orifice plate of the present invention is arranged on bushing air-conditioner wind bellows 1, bushing air-conditioner wind bellows 1 is provided with bushing bellows controlled valve 8, and employing bushing bellows controlled valve 8 regulates the air-conditioner wind through orifice plate 2.Orifice plate 2 and bushing air-conditioner wind bellows 1 are arranged on the actual production line operator crown, and air-conditioning bellows connect main air duct.Air-conditioner wind is blowed by main air duct, and the air quantity that main air duct send can not adjust in certain hour section, and air quantity is regulated by bushing bellows controlled valve 8.In actual production, wind blows from main air duct, and orifice plate is outside, and be tilted to the right assembling, and inclination angle is usually between 30 degree to 50 degree.
Produce certain specification 2400tex product for bushing air-conditioning bellows air intake wind speed 6.5m/s to be below described:
In summary, the present invention and conventional holes plate structure structure compared simple, to be skillfully constructed and easy to use.The bushing air-conditioner wind air-out uniformity adopting the present invention to produce is good, little to the perturbation of fiber, is more conducive to forming stable temperature field; Owing to solving the uneven problem of bushing air-conditioner wind air-out, be coated with the temperature deviation of oil drop because this reducing bushing two ends, the temperature deviation making bushing two ends be coated with oil drop diminishes, and is conducive to the stable of product quality.The yarn linear density good stability produced, product wool yarn is few.
It should be pointed out that the above detailed description of the invention can make the invention of those skilled in the art's comprehend, but do not limit the present invention in any way creation.Therefore; although this description has been described in detail the invention with reference to drawings and Examples; but; those skilled in the art are to be understood that; still can modify to the invention or equivalent replacement; in a word, all do not depart from technical scheme and the change thereof of the spirit and scope of the invention, and it all should be encompassed in the middle of the protection domain of the invention patent.
