Document Type and Number:
Japanese Patent JP2829417
Kind Code:
B2
Abstract:
Apparatus for thickening a suspension of pulp material which includes an endless foraminous belt (30) wrapping two spaced horizontally supported rolls (20,22). A doctor mechanism is provided for transferring thickened pulp from the surface of the second roll (22) into a trough (50) mounted in the space bounded by the two rolls (20,22) and the upper and lower runs of the belt (30). The doctor mechanism includes a rigid doctor blade (55) mounted with its working edge in close but spaced relation with the bare surface of the roll (22) to remove pulp therefrom without contact with the roll surface. The mounting apparatus periodically oscillates the blade (55) about a horizontal axis to move its working edge away from and back to its closely spaced working relation with the roll (22).
