Rotary type compressive filtrating machine

摘要

A rotary type compressive filtrating machine (1) capable of increasing a dewatering efficiency of a dewatering cake to be discharged, wherein unprocessed stock solution is led continuously into a filtration chamber (10) formed in a rectangular cross-section and extending annularly to rotatingly move a permeable donut-shaped screen (5) continuously in the end direction of the filtration chamber (10) in order to move, while compressing, the stock solution successively in the end direction by a friction between the unprocessed stock solution and the screen (5) in the filtration chamber (10), and a pressurizing plate (13) is provided in the filtration chamber (10) so that the cross-sectional area of the filtration chamber (10) is reduced gradually toward the moving direction of the unprocessed stock solution.
