摘要
A vacuum expressor device for a rotary drum vacuum filter (10) comprises an impermeable press belt membrane (35) mounted on a roll (21, 22) assembly atop the filter and adapted to be drawn into contact with the filter cake (15) by the vacuum within the filter drum (11) during the filtration cycle. The roll assembly (20) is mounted on the filter by a plurality of pneumatic actuators (39) for providing means for moving the press belt (35) towards or away from the filter drum (11).
