Description
Technical field
The utility model relates to a kind of papermaking press mechanical technique apparatus field, and particularly a kind of taper hole vacuum is inhaled and moved pressure roller.
Background technology
The major function of press section of a paper machine is dehydration, solidifies page, improves page characteristic simultaneously, improves wet web strength to improve the drying capacity of drying section.Vacuum inhales that to move pressure roller are key equipments of realizing the separated major function of press section page, and Modern Paper Machine is due to the higher speed of a motor vehicle, use vacuum to inhale to move pressure roller can improve dewatering efficiency, improve page quality, reduce the adverse effect that squeezing paper feeding industry is brought.The main feature that vacuum suction moves pressure roller is on roller shell, to have the through hole that a lot of diameters are less, and through hole is by liners and body layer, and during work, roller shell inner chamber maintains lasting vacuum.The effect of vacuum furnace inner chamber vacuum is: force the moisture that nip is extruded to pass blanket net, through vacuum, inhale and move the through hole on roller, enter roller shell inner chamber.This process need regular hour, the vacuum of vacuum furnace region of no pressure is higher, and this time is shorter, just has more moisture to be sucked out within the identical time, and page separation is easier, and dehydrating effect is better.
Improve paper machine speed, the dewatering efficiency that requires the suction of paper machine vacuum to move pressure roller improves, and one of them method is to improve the line pressure of nip; The linear pressure of nip is larger, and page dehydration is more, but because page may be by conquassation, line pressure can not be too; And line pressure is larger, the frame of press section and the rigidity of roller increase, and making apparatus need be used more steel, and operation will consume the more energy.
In prior art, vacuum suction moves pressure roller surface and by blind hole is set, improves the dehydration of press section of a paper machine, thereby effectively eliminates embossing phenomenon; The water separation capability that improves vacuum furnace can realize by increasing the quantity of through hole on roller shell, because through hole is by liners and body layer, perforate meeting has influence on the bulk strength of vacuum furnace too much, affect conversely the raising of line pressure, and on paper, leave " ghost ", so vacuum inhales that to move the percent opening on pressure roller surface restricted, causes vacuum to be inhaled moving pressure roller limited to improving the water separation capability of press section of a paper machine, thereby make the aridity of finished paper not high, restricting the raising of paper machine speed.
