Description
Technical field
It the utility model is related to the technical field of drying unit, especially a kind of drying unit for paper machine.
Background technology
Paper machine is the joint equipment of paper making, is mainly made up of the part such as net, squeezing and drying.Mesh portions cylinder and
Two kinds of fourdrinier wire, press section is made up of pressure roller and papermaker's felt etc., and drying section is made up of one or several drying cylinders.
In drying section, it is divided into preceding group of drying cylinder and rear group drying cylinder, typically respectively there are 6 drying cylinders, 12 altogether.While and preceding group of baking
Two groups of dry net circle roads that cylinder and rear group drying cylinder are used in combination（Plain net）, they one from another is tight by page from below above
It is pressed onto on the cylinder surfaces of heating.The drying of page is to absorb heat by the tight drying cylinder of l Water Paper signature progressively to evaporate moisture to reach
To the mass dryness fraction of Product Process requirement.
Wherein dry net circle road is mainly made up of braided polyester and some deflector rolls；The dry net of braided polyester is divided by species, can be divided
Dry net is woven for one layer of half-dried net, double-deck dry net, flat filament drying net, double footpath flat filament drying nets and special materials（Plain net）.
The dry net of braided polyester when one from above another from when page is pressed onto on the cylinder surfaces of heating below, due to
The dry net of braided polyester is in drying box and page contains moisture, and the dry net of braided polyester can also be stained with substantial amounts of moisture；So in paper
Page in dried kind, close to the moisture of drying cylinder dried rapidly by page；And because the dry net of braided polyester can be also stained with largely
Moisture；Page can not obtain drying in time close to drying cylinder free surface moisture；It is irregular and cause drying to cause moisture distribution inside and outside page
Gloss, color and the other physical properties of page positive and negative afterwards can not being consistent property.
China Patent Publication No. is 2048483, and the entitled paper machine dryer group driven with deflector roll, it discloses one
The dry net circle road of kind, but also without solution above-mentioned technical problem.
The content of the invention
In order to solve above-mentioned technical problem, the utility model provides a kind of papermaking drying for being used to improve page quality
With dry net circle road.
The technical solution of the utility model is：
Papermaking drying dry net circle road, including dry net and some deflector rolls, do excessively some deflector roll positioning windings of Netcom in drying cylinder
On, one closed-loop path of each formation of net is done, the front of dry net is adjacent to the drying cylinder face contacted, and dry net is driven to do and followed for no reason by drying cylinder
Inscription of loop, dry net are the dry net of braided polyester；Dry net circle road is additionally provided with least one heating roller for being used to heat dry net.
Further, above-mentioned heating roller heats to steam water.
Further, a diameter of 400cm of above-mentioned heating roller.
Further, two groups of dry net circle roads of preceding group of drying cylinder and rear group drying cylinder are divided into dry net circle road and lower dry net circle road,
The heating roller on upper dry net circle road is placed in preceding group of drying cylinder and rear group drying cylinder upper end；Down the heating roller on dry net circle road be placed in preceding group of drying cylinder and
Drying cylinder lower end is organized afterwards.
The beneficial effects of the utility model are：Because heating roller is also also carried out the dry net of braided polyester in baking oven simultaneously
Heat and unwatering, one, the dry net of braided polyester from above another page is pressed onto on the cylinder surfaces of heating from below
When, page simultaneously by interior external heat, inside and outside such page moisture loss basically reach unanimously, reached free surface moisture in page and divided
Cloth is uniform, and makes gloss, color and other the being consistent property of physical property of its positive and negative.
Heating roller, which is set, does not change former drying unit, steams the mode of heating one of water heating and former drying unit and causes work
Part is easy to process and reduces production cost.
Brief description of the drawings
Fig. 1 is the upper and lower dry net circle line structure schematic diagram of preceding net drying cylinder paper grade (stock) of the present utility model；
The dry nets of 1- in figure；2- heating rollers；3- deflector rolls；4- drying cylinders.
Embodiment
The explanation under is made to the present invention below in conjunction with the accompanying drawings：
It is the upper and lower dry net circle line structure signal of preceding net drying cylinder paper grade (stock) of the present utility model referring to Fig. 1
Figure,
Dry net circle road includes dry net 1 and some deflector rolls 3, does excessively some deflector roll positioning windings of Netcom on drying cylinder 4, dry net 1
A closed-loop path is respectively formed, the front of dry net 1 is adjacent to the drying cylinder face contacted, and dry net 1 is driven by drying cylinder 4 and does circulating for no reason
OK, dry net 1 is the dry net of braided polyester；Dry net circle road is additionally provided with the heating roller 2 of one.
Wherein two groups dry net circle roads are divided into dry net circle road and lower dry net circle road, before the heating roller 2 on upper dry net circle road is placed in
Group drying cylinder upper end；The heating roller 2 on dry net circle road is placed in rear group of drying cylinder lower end down.
The utility model Fig. 1 only draws preceding group of drying cylinder, and rear its basic structure of drying cylinder of organizing is as preceding group of drying cylinder, herein simply
Explanation.
The structure of heating roller can also be heated as cylinder structure with steam；They all make it with steam heating simultaneously
Other mode of heatings are not needed, reduce cost.
The diameter of drying cylinder is about 1500cm, and the diameter of heating roller is about 400cm；The diameter of heating roller crosses ambassador's steam wave
Take and make dry net temperature drift, it is too small not reach vapor and heating effect.
The dry net of braided polyester is divided by species, can be divided into one layer of half-dried net, double-deck dry net, flat filament drying net, double footpath flat filament dryings
Net and special materials weave dry net（Plain net）.
The steam mode of heating of drying cylinder of the present utility model is prior art；The application need not one in this as prior art
One description.
The utility model is compared with existing painting spray apparatus, the quality of paper can be significantly improved, because heating roller is in baking oven
Also the dry net of braided polyester has also been carried out simultaneously heating and unwatering, one, the dry net of braided polyester from above another under
When page is pressed onto on the cylinder surfaces of heating by face, page is simultaneously by interior external heat, and moisture loss is basic inside and outside such page
Reach consistent, reached that moisture distribution inside and outside page is uniform, and keep gloss, color and the other physical properties of its positive and negative
Uniformity.
1. wire side eliminates two sides aberration, originally paper two sides aberration is obvious, no color differnece after improvement without steam；
2. eliminating reticulate pattern using plain net, the flatness of paper is added；
3. improving speed, 10% production capacity is added；
The quality index (list) specifically surveyed：
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, for this
For the technical staff in field, the present invention can have various modifications and variations.It is all within the spirit and principles of the utility model,
Any modification, equivalent substitution and improvements made etc., should be included within the scope of protection of the utility model.
