Abstract
PURPOSE: To improve the dehydration performance of the belt press by parallel disposing a multiplicity of small-diameter rolls and continuously decreasing the radii of curvature thereby forming the pressing path of increasing compression pressure.
CONSTITUTION: The dehydrating device which performs dehydration of slurry by placing the slurry between two sheets of webs, at least one whereof is water permeable, and applying pressure to two sheets of the webs along the pressing path. The pressing path is constituted by the pressing path 2 of the continuously or pseudo- continuously decreasing radii of curvature and the pressing path 3 of conversely increasing radii of curvature. The slurry fed from an inlet 7, is held between two sheets of the webs and is dehydrated by the pressure increasing gradually along the pressing path 2 up to the roll of the smallest radius of curvature. Thereupon, it is inverted by an invertion roll 4 and this time it is applied with bending stress in the opposite direction and is dehydrated while moving along the pressing path 3. At an outlet 8, it is discharged from the dehydrator.
