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 the drying cylinder gas hood, especially relate to a kind of drying cylinder gas hood and use air-blast device.
Background technology
Be the paper quality that guarantees that paper machine dryer is dried out, all be provided with gas hood in the paper machine dryer outside.But autumn and winter cold weather, humidity is bigger in the paper machine room, and drying cylinder vapour cover internal temperature is high, drying cylinder vapour cover wet end is drawn into clammy air, adheres to the globule at vapour cover inwall easily, causes paper that the water droplet hole is arranged, and has a strong impact on original paper quality.
The existing Zhijiang River, river BF-10 Flying Dutchman gas hood is equipped with adjustable deep bead near cadre's suction opeing, is mainly used in to regulate cadre's intake.In actual production process, when cadre's air inlet reached maximum, intake was still smaller, caused cadre's gas hood steam to gather; Condense at the gas hood top, produce dripping phenomenon, cause the body paper hole of dripping; Original paper quality is defective, produces a large amount of quality and copies back loss, directly increases production loss.
Summary of the invention
The object of the invention is exactly to provide a kind of can effectively alleviate the body paper hole occurrence probability that drips in order to overcome the defective that above-mentioned prior art exists, and reduces the drying cylinder gas hood of mass loss and uses air-blast device.
The object of the invention can be realized through following technical scheme: a kind of drying cylinder gas hood is used air-blast device, it is characterized in that, comprises air blast; Connect flexible pipe, stainless steel tube, described air blast connects stainless steel tube through connecting flexible pipe; Described stainless steel tube is arranged on the gas hood below, and the stainless steel tube top is provided with blowing mouth, and this blowing mouth is over against gas hood cadre air inlet;, drive gas hood cadre moist steam and move, and then take away to gas hood cadre balanced ventilation through air blast by the gas hood blower fan to wet end.
The length of described stainless steel tube is identical with the gas hood width.
Blowing mouth on the described stainless steel tube is the steel pipe longitudinal opening.
Wide 3～the 5mm of described blowing mouth.
Compared with prior art, the present invention is transformed into air blast with deep bead, can quicken flow of water vapor in the gas hood, helps the gas hood blower fan and faster steam is taken away, thereby avoid steam in gas hood, to condense, and produces dripping phenomenon.Thereby effectively alleviate the body paper hole occurrence probability that drips, reduce mass loss.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the sketch map of stainless steel tube blowing oral-lateral of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is elaborated.
Shown in Fig. 1～2, a kind of drying cylinder gas hood is used air-blast device, comprises a 3KW air blast 1; Connect flexible pipe 2, stainless steel tube 3, described air blast 1 connects stainless steel tube 3 through connecting flexible pipe 2; Described stainless steel tube 3 is arranged on gas hood 4 belows, and 3～5mm blowing mouth 5 is vertically opened in stainless steel tube 3 tops, and this blowing mouth 5 is over against gas hood 4 cadre's air inlets;, drive gas hood cadre moist steam and move, and then take away to gas hood cadre balanced ventilation through air blast by the gas hood blower fan to wet end.Gather at cadre's gas hood thereby reduce steam, generation is dripped.
Claims (4)
1. a drying cylinder gas hood is used air-blast device, it is characterized in that, comprises air blast; Connect flexible pipe, stainless steel tube, described air blast connects stainless steel tube through connecting flexible pipe; Described stainless steel tube is arranged on the gas hood below, and the stainless steel tube top is provided with blowing mouth, and this blowing mouth is over against gas hood cadre air inlet;, drive gas hood cadre moist steam and move, and then take away to gas hood cadre balanced ventilation through air blast by the gas hood blower fan to wet end.
2. a kind of drying cylinder gas hood according to claim 1 is used air-blast device, it is characterized in that, the length of described stainless steel tube is identical with the gas hood width.
