ABSTRACT:
A suction dewatering system which includes a suction device adapted to be connected to a source of suction and having at least one longitudinal opening therein to which suction can be applied. The opening is positioned substantially perpendicular to the direction of medium travel across the suction device for dewatering thereof. An adjustable slot cover is provided for the suction device and includes a base. The base is mounted to the suction device in fixed position and has surfaces thereon forming spaced longitudinal lands and defining a longitudinal slot between each pair of adjacent lands in alignment with the suction device opening. A wear strip is removably positioned on each of the lands for engagement with the medium passing thereover. The wear strip on one of each pair of adjacent lands is stationary in respect to the direction of medium travel and the wear strip on the other of the pair of adjacent lands is automatically adjustable with respect to the direction of medium travel. Controls are responsive to change in medium conditions traveling over the suction device and automatically adjust the position of the adjustable wear strip and vary the slot width accordingly. One of the land and the adjustable wear strip mounted thereon has an oblique slot therein angularly directed with respect to the longitudinal slot and the other of the land and adjustable wear strip thereon has a rail extending therefrom at an oblique angle with respect to the longitudinal slot and extending into the oblique slot so that when the adjustable wear strip is moved longitudinally it will be shifted laterally with respect to the slot thereby changing the width of the slot opening.
