Description
Technical field
The utility model relates to a kind of papermaking press mechanical technique apparatus field, and particularly a kind of blind slot 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 be to realize press section page to separate the key equipment of major function, 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 when 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, inhale the through hole moving on roller through vacuum, 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 it is easier that page separates, and dehydrating effect is better.
In prior art, vacuum suction moves pressure roller surface and improves the dehydration of press section of a paper machine by blind hole is set, thereby effectively eliminates embossing phenomenon, although small diameter circular blind hole has certain dehydration, because aperture is little, air is left in inside, contained air, while entering nip, the air in blind hole can hinder entering of water, affects the water capacity of blind hole, further affects the dewatering efficiency of blind hole, while leaving nip, in blind hole, air can return to normal pressure, thereby can promote the discharge of moisture in blind hole, but along with the operation of suction press roll, in blind hole, experience is carried out repeatedly to moisture enters and discharge process, therefore, blind hole is forced moistening, and water-filling is inevitable, once air is substituted by moisture in blind hole, in described blind hole, will retain the moisture of part, blind hole to moisture siphonage under, even through the centrifugal action of suction press roll, can be by the whole moisture emptyings in blind hole yet, thereby have influence on the water capacity of circular blind hole, directly affect the dewatering efficiency of suction press roll, thereby make the aridity of finished paper not high, restricting the raising of paper machine speed.
