Description
Technical field
The utility model belongs to paper making equipment technical field, specifically, relates to a kind of paper-making drying cylinder drying device.
Background technology
In the process of wet papermaking, the drying of l Water Paper has heated-air drying and cylinder dried two kinds of forms usually, general cylinder dried device is made up of upper row's cylinder group and lower row's cylinder group and dry net and some deflector rolls, dry net is polyester spiral net or plain net, being wound around by deflector roll makes the dry net of part be close on drying cylinder cylinder face, and the closed-loop path that dry net is formed is provided with stretcher and adjuster carries out tensioning and correction to dry net.Dry net stretcher and corrector roll are installed in the upper loop of dry net, and for adjusting the elasticity of dry net and rectifying a deviation to dry net, other deflector rolls play guiding and supporting role to dry net;
Because l Water Paper moisture is large, surface strength is poor, under drying cylinder cylinder face and the adhesion doing net and rubbing action, the surface of l Water Paper has small part paper hair and filler, chemical industry etc. and splits away off the drying cylinder cylinder face and dry online of sticking to, the bur sticked on drying cylinder cylinder face can scrape off with dryer scraper, the bottom in prior art, dryer scraper being arranged on drying cylinder paper delivery end does not contact the proper site of paper, plays cleaning action to drying cylinder cylinder face.
But stick to dry online bur then can transfer on deflector roll and form pitchy block, these pitchy blocks falling down of not timing can be formed blob of viscose by dry guipure by dry net friction to the paper in drying cylinder portion, easily cause quality problems.The water vapour evaporated because of l Water Paper is again up discharge from bottom under the effect of drying cylinder gas hood top exhaust blower; the dry net wire side of the row's of causing drying cylinder is moist and more easily adhere to the burs such as paper hair; therefore the dirty patch that on dry net deflector roll, bur is formed is gone up more; need regularly or irregularly to shut down to carry out striking off cleaning, have a strong impact on the quality of paper and the output of paper machine.
If in the upper and lower dry net loop in general cylinder dried device, two diameters are used to replace dry net to go out the common deflector roll of certain root compared with front end after drying cylinder times over the adhesion roller of common deflector roll, and scraper is set at adhesion roll surface the bur sticked on roll surface is struck off, then can reach clean dry net and reduce the hidden danger that bur forms dirty patch, by deriving the purpose of this utility model.

Detailed description of the invention
The utility model specifically can be implemented by the technology illustrated in technical scheme, and by the following examples can the utility model will be further described, but scope of the present utility model is not limited to following embodiment.
Embodiment 1: see Fig. 1-3;
Upper row's cylinder group is made up of four upper row's drying cylinders 2, upper row's dryer scraper 4 is also had in figure, upper row's deflector roll 5, on drain net stretcher 6, upper row's corrector roll 7, upper row's adhesion roller 10, upper row's scraper 8 and upper dry net 9 etc., wherein the bottom of upper row dryer scraper 4 row of being arranged on drying cylinder 2 paper delivery end does not contact the correct position of paper, cleaning action is risen to upper row's drying cylinder 2 cylinder face, on drain net stretcher 6 and upper row's corrector roll 7 is installed in the upper loop of dry net, for adjusting the elasticity of upper dry net and rectifying a deviation to upper dry net, the comparatively front end in upper row's adhesion roller 10 upper dry net loop after being arranged on out drying cylinder, on the roller seat of upper row's scraper 8 row of being arranged on adhesion roller 10, other are arranged deflector roll 5 and guiding and supporting role are risen to upper dry net,
Lower row's cylinder group is made up of four lower row's drying cylinders 3, lower row's dryer scraper 13 is also had in figure, lower row's deflector roll 14, under drain net stretcher 15, lower row's adhesion roller 16, lower row's scraper 12, corrector roll 17 and lower dry net 11 etc., wherein lower row's dryer scraper 13 is arranged on the correct position that lower row's drying cylinder 3 top does not contact paper, cleaning action is risen to lower row's drying cylinder 3 cylinder face, under drain net stretcher 15 and corrector roll 17 is installed in the lower loop of lower dry net, for adjusting the elasticity of lower dry net and rectifying a deviation to lower dry net, the comparatively front end in lower row's adhesion roller 16 lower dry net loop after being arranged on out drying cylinder, lower row's scraper 12 is arranged on the roller seat of lower row's adhesion roller 16, other lower row's deflector rolls 14 play guiding and supporting role to lower dry net.
The l Water Paper going out press section enters oven dry portion dries, first wet web is introduced lower between dry net 11 and lower row's drying cylinder 3, l Water Paper is close to cylinder face in the part of the coated drying cylinder of lower dry net 11, l Water Paper to go out after lower row's drying cylinder 3 again between the row's of being introduced into drying cylinder 2 and upper dry net 9, wet web is close to cylinder face in the part of the coated drying cylinder of upper dry net 9, conducted heat by drying cylinder, wet web moisture becomes water vapour gradually and evaporates and discharged by the exhaust blower of drying cylinder gas hood side, through the oven dry of some drying cylinders, subsequent processings such as batching is entered after the paper web moisture going out oven dry portion reaches the moisture requirement of finished paper.
In last, the two drying cylinder sections in oven dry portion, because l Water Paper moisture is large, surface strength is poor, under drying cylinder cylinder face and the adhesion doing net and rubbing action, the surface of l Water Paper has small part paper hair and filler, chemical industry etc. and splits away off the drying cylinder cylinder face and dry online of sticking to, the bur sticked on drying cylinder cylinder face is struck off by dryer scraper, and the bur scraped off falls into the dust collecting trough of scraper.
The most burs sticked on dry net 9 are struck off by upper row's scraper 8 compared with on upper row's adhesion roller 10 of front end after then transferring to and being arranged on out drying cylinder, and the bur scraped off falls into the dust collecting trough of scraper.
