Abstract
The invention relates to an air blowing device for a dryer air cover, comprising an air blower, a connecting hose and a stainless steel pipe, wherein the air blower is connected with the stainless steel pipe through the connecting hose; the stainless steel pipe is arranged below a dry part air inlet of the air cover and an air blowing opening is arranged above the stainless steel pipe; the air blowing opening is aligned with the dry part air inlet of the air cover; and air is uniformly conveyed into a dry part of the air cover through the air blower to drive wet steam of the dry part of the air cover to move towards a wet part, so as to pump out by the air blower of the air cover. Compared with the prior art, the air blowing device for the dryer air cover has the advantages of effectively reducing the generation possibility of water dripping holes on raw paper, reducing the mass loss and the like.
Description
Technical field
The present invention relates to drying cylinder gas hood, especially relate to a kind of drying cylinder gas hood air-blast device.
Background technology
For ensureing the paper quality that paper machine dryer is dried out, outside paper machine dryer, be all provided with gas hood.But autumn and winter cold weather, paper machine room humidity is comparatively large, and drying cylinder vapour cover internal temperature is high, and drying cylinder vapour cover wet end is drawn into clammy air, easily at the vapour cover inwall attachment globule, causes paper to have water droplet hole, has a strong impact on original paper quality.
The Zhijiang River, existing river BF-10 Flying Dutchman gas hood is equipped with adjustable deep bead near cadre's suction opeing, is mainly used in regulating cadre's intake.In actual production process, when cadre's air inlet reaches maximum, intake is still smaller, causes cadre's gas hood moisture accumulations, in the condensation of gas hood top, produce dripping phenomenon, cause body paper to drip hole, original paper quality is defective, produces a large amount of quality and copies back loss, directly increase production loss.
Summary of the invention
Object of the present invention is exactly provide one effectively can alleviate body paper to overcome defect that above-mentioned prior art exists to drip hole occurrence probability, reduce the drying cylinder gas hood air-blast device of mass loss.
Object of the present invention can be achieved through the following technical solutions: a kind of drying cylinder gas hood air-blast device, it is characterized in that, comprise air blast, connecting hose, stainless steel tube, described air blast connects stainless steel tube by connecting hose, and described stainless steel tube is arranged on below gas hood, is provided with blowing mouth above stainless steel tube, this blowing mouth is just to gas hood cadre air inlet, by air blast to gas hood cadre balanced ventilation, drive gas hood cadre moist steam to move to wet end, and then taken away by gas hood blower fan.
The length of described stainless steel tube is identical with gas hood width.
Blowing mouth on described stainless steel tube is steel pipe longitudinal opening.
Wide 3 ~ the 5mm of described blowing mouth.
Compared with prior art, deep bead is transformed into air blast by the present invention, can accelerate flow of water vapor in gas hood, is conducive to gas hood blower fan and is taken away by steam faster, thus avoid steam to condense in gas hood, produces dripping phenomenon.Thus effectively alleviate body paper and to drip hole occurrence probability, reduce mass loss.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the schematic diagram of stainless steel tube blowing mouth side of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment 1
As shown in Fig. 1 ~ 2, a kind of drying cylinder gas hood air-blast device, comprises a 3KW air blast 1, connecting hose 2, stainless steel tube 3, described air blast 1 connects stainless steel tube 3 by connecting hose 2, and described stainless steel tube 3 is arranged on below gas hood 4, longitudinally opens 3 ~ 5mm blowing mouth 5 above stainless steel tube 3, this blowing mouth 5 is just to gas hood 4 cadre air inlet, by air blast to gas hood cadre balanced ventilation, drive gas hood cadre moist steam to move to wet end, and then taken away by gas hood blower fan.Thus minimizing steam gathers at cadre's gas hood, generation is dripped.
Claims (4)
