Abstract
The invention relates to a dryer device comprising a dryer and a spray device which sprays on the surface of the dryer to form a coating; the dryer is used for drying a wet sheet; the coating is formed on the surface of the dryer; the spray device comprises a plurality of spray nozzles which are used for spraying the surface of the dryer; and the spray device can selectively adjust the spray flow of all the spray nozzles, so that the spraying amount on thin areas of the coating on the surface of the dryer is larger than that of the thicker areas of the coating on the surface of the dryer. According to the dryer device, the spray device is arranged beside the dryer and sprays on the surface of the dryer to form the coating, the thickness of the coating on the surface of the whole dryer is more uniform.
Description
Technical field
The present invention relates to a kind of dryer device.
Background technology
In wrinkling paper manufacturing process, the flexibility of thin paper, loosing character, draftability and absorbability etc. generally realize by Flying Dutchman drying and scraper.The coating of dryer surface contains pastes the cylinder agent, other chemical substance of adding before the remover, modifier and wet end.The drying cylinder coating should have good subsides cylinder, fissility and be even, durable and soft rete preferably.Prior art will be sprayed into dryer surface by the some nozzles on the spray pipe after normally will pasting cylinder agent, remover and modifier mixing.The flow of these some spray pipe nozzles is controlled by a pump, so the coating that can guarantee to spray on the drying cylinder is uniform.
Yet the slurry in the case is shaped to dewater at forming net and transfers to woollen blanket, and woollen blanket is with further dehydration of wet web process squeezing, transfer to again on the drying cylinder, if woollen blanket is excessively wet, when wet web was dry on transferring to drying cylinder, the water on the woollen blanket can be washed a part of coating of dryer surface off; Or wet web dewatered inhomogeneously before upper drying cylinder, when wet web is dry on transferring to drying cylinder, can wash a part of coating off, caused the inhomogeneous or other reasons of drying cylinder coating to cause that the drying cylinder coating is inhomogeneous.The zone that coating is thin, the subsides cylinder of coating is bad, and the heat energy of drying cylinder can not be delivered on the wet web effectively, and paper can not be dried effectively, causes that the paper uneven drying is even.The paper uneven drying is even can to affect the wrinkling inhomogeneous of paper, finally affects the performances such as intensity, pliability and bulk of thin paper.Coating is inhomogeneous also can to cause the disconnected paper of swaging clamp in paper-making process, also may cause drying cylinder and creping blade excessive wear.When such situation occured, the thickness that can increase coating increased the subsides cylinder of coating.Because the flow of existing spray pipe nozzle is controlled by a pump, adjusting flow is to adjust at whole dryer surface, local coating is inhomogeneous just to increase the coating spraying amount at whole dryer surface, so not only cause the waste of chemical drug, also can cause whole drying cylinder overweight coating, the overweight coating meeting can cause the pin hole problem of appearance of paper so that the coating hardening, also can cause the wearing and tearing of creping doctor.At this moment need to remove coating with cleaning doctor, rebulid coating, cause the waste of coating chemical drug.
Summary of the invention
In view of this, be necessary to provide a kind of dryer device, this dryer device can make the coating of dryer surface even.
A kind of dryer device, it comprises drying cylinder and in order to dryer surface is sprayed the spray equipment that forms coating, this drying cylinder is in order to dry wet web, the surface of this drying cylinder is formed with coating, this spray equipment comprises spraying a plurality of nozzles of dryer surface, this spray equipment can each nozzle of selective control the spraying flow, make the quantity for spray in the thin zone of dryer surface coating more than the zone of dryer surface thick coating.
The present invention arranges spray equipment by the next door at drying cylinder dryer surface is sprayed the formation coating, this spray equipment can each nozzle of selective control the spraying flow, make the coating chemical drug quantity for spray in the thin zone of dryer surface coating more than the zone of dryer surface thick coating, make the coating layer thickness of whole dryer surface more even.

The following specific embodiment further specifies the present invention in connection with above-mentioned accompanying drawing.
The specific embodiment
Dryer device of the present invention comprises drying cylinder and in order to dryer surface is sprayed the spray equipment that forms coating.The material of this spray equipment spraying contains coating chemical drugs such as pasting cylinder agent, remover and modifying agent.
See also Fig. 1, the outer surface of drying cylinder 10 of the present invention is formed with coating 12, and the width of this coating 12 is less than the width of drying cylinder 10 and greater than the width that is covered in the wet web of drying on drying cylinder 10 surfaces.
Please further consult Fig. 1, the spray equipment 30 of the present invention's the first preferred embodiment is arranged on the below of drying cylinder 10, spray equipment 30 can not be sprayed on the surf zone of wet web in the time of can guaranteeing like this drying cylinder 10 rotation, only can be sprayed on the surf zone that drying cylinder 10 is not covered by wet web.
This spray equipment 30 comprises a plurality of spray pipes 31, be communicated with on each spray pipe 31 and be provided with at least one nozzle 33, this nozzle 33 can be to drying cylinder 10 surface spraying coating chemical drugs, and the coating width that a plurality of nozzles 33 of these a plurality of spray pipe 31 correspondences are sprayed out and less than or equal to the width of drying cylinder 10, and more than or equal to the width of paper web.Each spray pipe 31 is communicated with a charging pump 37 by a pipeline 35, and each charging pump 37 connects holding tank 39 by pipeline 36 respectively, is equipped with the material of spraying in this holding tank 39.Each charging pump 37 can carry out flow-control, and then regulates the spraying flow of at least one nozzle 33 on each spray pipe 31 of control.The spray equipment 30 of the present invention's the first preferred embodiment comprises four spray pipes 31, is communicated with respectively on this four spray pipe 31 three or four nozzles 33 are set.
See also Fig. 2, slurry is shaped to dewater in the forming net (not shown) and transfers to woollen blanket 21, woollen blanket 21 carries the wet web (not shown) and squeezes further dehydration through pressure roller 23, transfer to again on the drying cylinder 10, dispose guard shield 25 outside the drying cylinder 10, this guard shield 25 is generally the hot blast guard shield, and guard shield 25 and drying cylinder 10 actings in conjunction are carried out drying to wet web, undertaken wrinklingly by 27 pairs of paper webs of scraper, the paper web that the downstream of drying cylinder 10 is provided with after 29 pairs of oven dry of scanner carries out the test of paper web moisture again.Paper web batches through scanner 29 again.
The high zone of scanner 29 test paper web moisture may be the zone of coating 12 thinner thicknesses on drying cylinder 10 surfaces, and in conjunction with the coating 12 of observing drying cylinder 10 surfaces, judges whether drying cylinder 10 face coats 12 are even.Then for the zone of coating 12 thinner thicknesses, increase the flow of corresponding charging pump 37, and then increase the spraying flow of the nozzle 33 of corresponding region.Be that the coating chemical drug quantity for spray in the thin zone of drying cylinder 10 face coats 12 zone thicker than drying cylinder 10 face coats 12 is more, make drying cylinder 10 face coats 12 thickness become even.
