Description
Technical field
The present invention relates to a kind of dryer device.
Background technology
In wrinkling paper manufacture process, the flexibility of thin paper, loosing character, draftability and absorbability etc. generally and scraper dry by Flying Dutchman realize.The coating of dryer surface contains sticker cylinder agent, remover, other chemical substance of adding before modifier and wet end.Good drying cylinder coating should have good pastes cylinder, fissility and be even, durable and soft rete.Prior art is sprayed into dryer surface by the some nozzles on spray pipe after normally sticker cylinder agent, remover and modifier being mixed.The flow of this some spray pipe nozzle is controlled by a pump, so can ensure that the coating sprayed on drying cylinder is uniform.
But the slurry in head case transfers to woollen blanket in forming net shaping dehydration, woollen blanket dewaters through squeezing further with wet web, transfer to again on drying cylinder, if woollen blanket is excessively wet, wet web is when transferring to dry on drying cylinder, and the water on woollen blanket can wash a part of coating of dryer surface off; Or wet web dewatered uneven before upper drying cylinder, wet web, when transferring on drying cylinder dry, can wash a part of coating off, causes the uneven or other reasons of drying cylinder coating to cause drying cylinder coating uneven.The region that coating is thin, the subsides cylinder of coating is bad, and the heat energy of drying cylinder can not be delivered on wet web effectively, and paper can not be dried effectively, causes paper uneven drying.Paper uneven drying can affect the wrinkling uneven of paper, finally affects the performances such as the intensity of thin paper, pliability and bulk.Coating is uneven also can cause swaging clamp in paper-making process to break paper, also may cause drying cylinder and creping blade excessive wear.When there is such situation, the thickness of coating can be increased to increase the subsides cylinder of coating.Because the flow of existing spray pipe nozzle is controlled by a pump, adjustment flow adjusts at whole dryer surface, the coating of local is uneven just increases coating spraying amount at whole dryer surface, so not only cause the waste of chemical drug, also can cause whole drying cylinder overweight coating, overweight coating can make coating hardening, can cause the pin hole problem of appearance of paper, also can cause the wearing and tearing of creping doctor.At this moment need to remove coating with cleaning doctor, re-establish 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 uniform of dryer surface.
A kind of dryer device, it comprises drying cylinder and the spray equipment in order to carry out spraying formation coating to dryer surface, this drying cylinder is in order to dry wet web, the surface of this drying cylinder is formed with coating, this spray equipment comprises the multiple nozzles spraying dryer surface, this spray equipment can the spraying flow of each nozzle of selective control, makes the quantity for spray in the region that dryer surface coating is thin more than the region of dryer surface thick coating; Be configured with guard shield outside drying cylinder, guard shield is hot blast guard shield; This spray equipment comprises four spray pipes, spray pipe is communicated with respectively three or four nozzles arranging at equal intervals, each spray pipe is by pipeline communication one charging pump, each charging pump is connected the holding tank being equipped with spraying substance respectively by pipeline, each charging pump can carry out flow-control, and then the spraying flow of at least one nozzle on each spray pipe of regulable control; This nozzle is to dryer surface spray-on coating chemical drug, and multiple nozzle coating widths sprayed out and the width being less than or equal to drying cylinder, and be more than or equal to the width of paper web; The downstream of this drying cylinder is provided with scanner carries out paper web moisture test to the paper web after oven dry, the region that scanner test paper web moisture is high may be the region that the coating layer thickness of dryer surface is thinner, and combine the coating of observing dryer surface, judge that whether dryer surface coating is even, then for the region that coating layer thickness is thinner, increase the flow of corresponding charging pump, and then the spraying flow of the nozzle of increase corresponding region.
The present invention carries out spraying formation coating by arranging spray equipment on the side of drying cylinder to dryer surface, this spray equipment can the spraying flow of each nozzle of selective control, make the coating chemical drug quantity for spray in the region that dryer surface coating is thin more than the region of dryer surface thick coating, make the coating layer thickness of whole dryer surface more even.

Following detailed description of the invention will further illustrate the present invention in conjunction with above-mentioned accompanying drawing.
Detailed description of the invention
Dryer device of the present invention comprises drying cylinder and the spray equipment in order to carry out spraying formation coating to dryer surface.The material of this spray equipment spraying contains the coating chemical drugs such as sticker cylinder agent, remover and modifying agent.
Refer to 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 is greater than and is covered in the width that the wet web of drying is carried out on drying cylinder 10 surface.
Please consult Fig. 1 further, the spray equipment 30 of the present invention first preferred embodiment is arranged on the below of drying cylinder 10, when can ensure that drying cylinder 10 rotates like this, spray equipment 30 can not be sprayed on the surf zone of wet web, only can be sprayed on drying cylinder 10 not by surf zone that wet web covers.
This spray equipment 30 comprises multiple spray pipe 31, each spray pipe 31 is communicated with and is provided with at least one nozzle 33, this nozzle 33 can to drying cylinder 10 surface spraying coating chemical drug, and multiple nozzles 33 of the plurality of spray pipe 31 the correspondence coating widths sprayed out and the width being less than or equal to drying cylinder 10, and be 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 the spraying flow of at least one nozzle 33 on each spray pipe 31 of regulable control.The spray equipment 30 of the present invention first preferred embodiment comprises four spray pipes 31, this four spray pipe 31 is communicated with respectively and arranges three or four nozzles 33.
Refer to Fig. 2, slurry transfers to woollen blanket 21 in forming net (not shown) shaping dehydration, woollen blanket 21 carries wet web (not shown) to carry out squeezing further dehydration through pressure roller 23, transfer on drying cylinder 10 again, guard shield 25 is configured with outside drying cylinder 10, this guard shield 25 is generally hot blast guard shield, guard shield 25 and drying cylinder 10 acting in conjunction carry out drying to wet web, undertaken wrinkling by scraper 27 pairs of paper webs again, the downstream of drying cylinder 10 is provided with scanner 29 carries out paper web moisture test to the paper web after oven dry.Paper web batches through scanner 29 again.
The region that the high region of paper web moisture may be coating 12 thinner thickness on drying cylinder 10 surface tested by scanner 29, and combines the coating 12 of observing drying cylinder 10 surface, judges that whether drying cylinder 10 face coat 12 is even.Then for the region of coating 12 thinner thickness, the flow of corresponding charging pump 37 is increased, and then the spraying flow of the nozzle 33 of increase corresponding region.The region that the coating chemical drug quantity for spray in the region that namely drying cylinder 10 face coat 12 is thin is thicker than drying cylinder 10 face coat 12 is more, makes drying cylinder 10 face coat 12 thickness become even.
