ABSTRACT:
A constant flow felt dewatering system including first and second suction pipes with a slot in each pipe. A felt is positioned to pass over the slots of the first and second pipes. A centrifugal exhauster is connected by conduits to the first and second suction pipes. Drive structure is provided to operate the centrifugal exhauster and apply suction to the first and second suction pipes and to advance the felt over the pipes whereupon suction is applied thereto to dewater the felt. Controls are responsive to change in felt conditions to vary the dwell time of the felt with respect to the slots in order to maintain a substantially constant flow.
