1. Description of Vacuum Press Roller
Vacuum presses are widely used in medium and high-speed paper machines, and are also an indispensable part of compound presses.
The layout of a general vacuum press and its ancillary equipment are similar to those of an ordinary press. However, the eccentricity of the vacuum press is opposite to that of the traditional press, that is, the upper roller of the press is offset by 50 to 60 mm in the outlet direction relative to the lower roller.
To remove moisture from the press section, the vacuum chamber suction in the vacuum roll must be directed towards the feed side of the nip. Only in this way, the felt and wet paper first come into contact with the vacuum roller, so that the sealing effect of the nozzle of the vacuum chamber can be achieved, preventing air from entering the vacuum system. Therefore, the felt generally enters the pressing section in the horizontal downward direction, and then moves away from the pressing section in the horizontal downward direction.
