Abstract
The utility model discloses an extra-large roller diameter squeezing device. The extra-large roller diameter squeezing device comprises a groove squeezing roller, a vacuum squeezing roller, an artificial stone roller, a blind hole squeezing roller, a large roller diameter artificial stone roller and a large roller diameter blind hole roller. According to the extra-large roller diameter squeezing device, the large roller diameter artificial stone roller and the large roller diameter blind hole roller are added to form a fourth squeezing area on the basis of the conventional four rollers and three squeezing areas, the moisture of paper webs is further eliminated, the paper webs enter a drying part under the action of sucking paper by blowing and an air suction box, and the dryness of paper sheets is effectively improved. Meanwhile, the air suction box is arranged before the larger roller is used for squeezing, and air between the paper webs and coarse cloth is exhausted.
Description
Technical field
The utility model relates to the papermaking equipment field, especially a kind of super large roller footpath pressing device.
Background technology
The squeezing form of paper machine has multiple, and high-speed paper machine uses compound squeezing usually.In common paper machine four roller tri-nip press devices; Paper web is inhaled by vacuum and is moved roller strap to paper injection felt; Carry out the squeezing of first road through suction press roll and fluted roller; Under the vacuum action of vacuum pressure roller, paper web is attached to the unipress that continues on the felt through other artificial stone roll and blind press composition, gets into oven dry portion then.Because paper web is only pressed through four rollers three, thereby the paper web moisture of entering oven dry portion is bigger.
The utility model content
The purpose of the utility model is to provide a kind of super large roller footpath pressing device of effective raising web dryness.
The technical scheme that realizes the utility model purpose is that a kind of super large roller footpath pressing device comprises grooved press roller, suction press roll, artificial stone roll and blind press, also comprises big roller footpath artificial stone roll and big roller footpath blind hole roller.
Said grooved press roller is close to suction press roll and is formed the two-sided pressed zone of the first road vacuum; Said suction press roll is close to the artificial stone roll and is formed suction press district, second road; Said artificial stone roll is close to blind press and forms the second road blind hole pressed zone; For being close to big roller footpath blind hole roller, big roller footpath artificial stone roll forms the 4th pressed zone after the second road blind hole pressed zone.
Said the 4th pressed zone front portion is provided with air-suction trunk.
Said the 4th pressed zone rear portion is provided with the air draught roller.
The utility model is on the basis of former four rollers, three nips; Increased big roller footpath artificial stone roll and formed the 4th nip, further got rid of the moisture of paper web, through the effect entering oven dry portion of blowing paper injection and air-suction trunk with big roller footpath blind hole roller; Improved web dryness effectively; Simultaneously, before the big roller squeezing, be provided with air-suction trunk, got rid of the air between paper web and the felt.
Description of drawings
Fig. 1 is the utility model sketch map.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
As shown in Figure 1; A kind of super large roller footpath pressing device; Comprise grooved press roller 1, suction press roll 2, artificial stone roll 3 and blind press 4; Be respectively equipped with the press felt 5 that l Water Paper is involved between grooved press roller 1, suction press roll 2, artificial stone roll 3 and the blind press 4, also comprise big roller footpath artificial stone roll 6 and big roller footpath blind hole roller 7.
Grooved press roller 1 is close to suction press roll 2 and is formed the two-sided pressed zone of the first road vacuum; Suction press roll 2 is close to artificial stone roll 3 and is formed suction press district, second road; Artificial stone roll 3 is close to blind press 4 and forms the 3rd road blind hole pressed zone; Big roller footpath artificial stone roll 6 forms the 4th road pressed zone with big roller footpath blind hole roller 7.
L Water Paper is adsorbed on press felt through suction press roll 2 and gets into the two-sided pressed zone in first road 5 times, and the l Water Paper page or leaf carries out double dewatering at this.The l Water Paper page or leaf further dewaters because the suction-operated of suction press roll 2 gets into suction press district, second road.Because l Water Paper chastity was separated with press felt 5 after the surface tension between l Water Paper page or leaf and the felt side less than the surface tension between itself and the stone roll, went out suction press district, second road, and along with artificial stone roll 3 gets into the second road blind hole pressed zone, continued dehydration.This moment, the mass dryness fraction of l Water Paper page or leaf obtained bigger raising, behind the artificial stone roll who is furnished with scraper 3 sur-face peelings, blew on the felt 9 through the blowing paper injection device 8 that is installed on the scraper again; Under the effect of air-suction trunk 10; Get rid of air between paper web and the felt, get into the 4th pressed zone of forming by big roller footpath artificial stone roll 6 and big roller footpath blind hole roller 7, further get rid of moisture again; Effectively improve squeezing efficient than prior art, the effect through blowing paper injection and air-suction trunk 11 at last gets into oven dry portion.
Claims (4)
