Abstract

PURPOSE:To dehydrate sludge under high pressure with only the adjustment of filter cloth tension without requiring a driving power device by constituting a titled dehydrator of tensioners for a filter cloth, movable rolls which are actuated by tension of the filter cloth, stationary rolls provided with a pressurizing belt and a tension roll which tenses the pressurizing belt cooperatively with the movable rolls. CONSTITUTION:When tension is generated to a filter cloth 1 by tensioners 3, 12 for the filter cloth, force acts on respective rolls No.1-No.3 of movable rolls 5 and forces sliding stands 20, 21 to move downward. A tension roll 8 is simultaneously forced to move downward by which tension is applied to a pressurizing belt 7. The belt 7 applied with the tension compresses the sludge sandwiched by the cloth 1 at stationary rolls 6 thereby dehydrating the sludge under high pressure. The higher tension may be further generated by adding a tension mechanism to the roll 8.

Then, in the roll (54), the p cloth (
1) is pressurized to the roll (54) side to perform high-pressure dewatering, and then the sludge is discharged as a dehydrated cake (Y). In the figure, (53) is a tension roll of the furnace cloth (1), which applies tension to the jOF cloth (1). (52) is a high-pressure belt (51), which is moved by a cylinder or the like to apply tension to the belt (51).
