A method and mechanism for dewatering fine coal or the like by a filtering operation including a horizontally disposed cylindrical housing defining a pressure chamber within, an intermittently movable filter belt wrapping support rolls for the belt at each end with the rolls having driving and braking devices, movable sealing devices positioned at openings to the chamber to seal the belt where it extends into and out of the chamber, a support for the belt with means for draining filtrate dewatered from the coal, and means to apply pressure to the chamber above the belt for dewatering the coal and for providing pressure beneath the support for the belt to balance forces within the housing. |
