Abstract
The utility model relates to a novel conveying and pressing unit for papermaking apparatuses, comprising a first double-felt pressing structure, a second and a third single-felt front pressing structures, a fourth smooth pressing structure. A double-felt pressing upper pressing roller (3), two single-felt front pressing lower pressing rollers (11), (16) are all provided with corrugated pressing roller structures which are provided with water receiving buckets (6), (13), (17). The conveying and pressing unit is mainly characterized in that the conveying and pressing unit overcomes the defect of heavy two-side on a paper web resulted from long net formation and single-side dewatering. The conveying and pressing unit is very suitable for producing various kinds of high-grade cultural paper of good quality with double-face coated and printed. The conveying and pressing unit can be also used as a pressing unit and applied on other papermaking apparatuses. The utility model improves dewatering efficiency, prolongs the service life of pressing rollers and felt, facilitates paper to be guided and improves running efficiency.
Description
The utility model belongs to paper machine, the new-type transmission pressing device of particularly a kind of paper machine.
Existing paper machine, under the fourdrinier forming condition, because of the single face dehydration causes the paper web dual character big, each road press dewatering poor effect, the service life of pressure roller and woollen blanket is shorter, and the press section operational efficiency is not high, thereby causes the paper quality to can not get reliable guarantee, yield rate is affected, and finally influences production efficiency.
The purpose of this utility model provides a kind of pressing device that is used to produce high-grade high-quality and many kinds cultural paper paper machine.Make paper web dual character reach minimum through its squeezing output, the press dewatering best results, pressure roller and felt life prolong, and production run efficient improves.
The new purpose of this practicality reaches by the design of the new-type transmission pressing device of following paper machine, this device mainly is made up of press mechanism, supporting device, imbibition woollen blanket, the press mechanism first road double felted press, second, third twice are single woollen blanket straight press, the 4th road is smooth squeezing, it is characterized in that the last pressure roller of the first road double felted press, the lower compression roller of second and third road squeezing all adopt the grooved press roll structure, and all have the water receiving bailing bucket, this water receiving bailing bucket is for having adjustable water saving scraper gulley groove groove structure; The last stone roll of second road squeezing is furnished with two mobile scrapers, and upper blade is provided with transport, is delivered directly in the broken pond in order to the broken that will scrape off, and this transport is mainly by the spiral promoting shaft 8 with broken breach, and sparge pipe 21 and cell body 22 are formed.
Fig. 1 is the utility model structural representation and embodiment;
Fig. 2 is a broken transport schematic diagram.
1. vacuum is inhaled and to be moved roller 2. woollen blankets 3. grooved press rollers 4. suction press roll 5. water doctors 6. water receivings 7. woollen blankets, 8. spiral promoting shafts, 9. scrapers, 10. stone rolls, 11. grooved press rollers, 12. water doctors, 13. water receivings, 14. single woollen blanket 15. stone rolls 16. grooved press rollers 17. water receivings, 18. stone rolls, 19. rubber rolls, 20. drying cylinders, 21. sparge pipes, 22. cell bodies of bailing of bailing of bailing
In force, per pass squeezing all adopt larger-diameter pressure roller, all pressure rollers all to be coated with anti-high line pressure (＞100KN/M) special rubber, each bar woollen blanket all has the high-efficient washing device.Below in conjunction with accompanying drawing is that example further specifies the utility model operation principle with the fourdrinier machine.Paper web moves roller 1 through the vacuum suction on the net from fourdriner forming and peels off and be adsorbed onto on the glazing felt 2, be clipped between the lower felt and squeeze, top roll is a grooved press roller 3, lower roll is a suction press roll 4, top roll has water receiving bailing bucket 6, the water receiving bailing bucket is the gulley groove groove structure of band water doctor 5, and water doctor can be regulated; Paper web obtains the double-side efficient dehydration simultaneously at the first road double felted press, again under suction press roll 4 suctions, enter the second road list woollen blanket rill straight press with lower felt 7, its lower roll is grooved press roller 11 and the water receiving bailing bucket 13 that has adjustable water saving scraper 12 gulley groove groove structures, top roll is a stone roll 10, this stone roll has two mobile scrapers 9, need again in the blink of paper injection in start or in producing, the transport that the paper web that is scraped by upper blade is formed via spiral promoting shaft 8 and water jet 21, cell body 22 directly is sent to broken under the fourdrinier wire in the broken pond; Behind the second road grooved press, effect based on efficient vertical dehydration mechanism, the paper web mass dryness fraction can reach 35～38% usually, thereby can begin open paper injection, enters and essentially identical the 3rd road list woollen blanket rill straight press in second road, the paper web mass dryness fraction further improves, can reach more than 40～43%, enter the smooth squeezing in the 4th road then, its lower roll is a stone roll 18, top roll is a rubber roll 19, after carrier rope is sent to drying cylinder 20.
The utility model has the advantages that to have overcome because the fourdriner forming single face dewaters causes the paper web dual character big Shortcoming, the tight ness rating that can reach the paper web two sides is basically identical, makes absorbefacient two sides, paper two sides Difference reaches minimum (the K﹠N value can reach 0～2%). Be particularly suitable for production two sided coatings, two-face printing High-grade many kinds of high-quality cultural paper also can be used as press section and is applied on other paper machine. In addition, use The press section that this programme is produced has also improved the press section dewatering efficiency, has prolonged making of pressure roller and woollen blanket Use the life-span, made things convenient for the paper injection operation, improved the operational efficiency of pressing device.
Claims (2)
1. new-type transmission pressing device of paper machine, form by press mechanism, supporting device and imbibition woollen blanket, press mechanism comprises the first road double felted press, the single woollen blanket straight press of second, third twice, the smooth squeezing in the 4th road, it is characterized in that the last pressure roller of the first road double felted press, the lower compression roller of the single woollen blanket straight press of second, third twice all adopt grooved press roller (16), the per pass squeezing all has water receiving bailing bucket (6), (13), (17).
2. the new-type transmission pressing device of a kind of according to claim 1 paper machine, its feature is that also the last stone roll (10) of second road squeezing is furnished with two mobile scrapers (9), and upper blade is provided with the transport of forming by with spiral promoting shaft (8), sparge pipe (21), the cell body (22) of broken breach.
