Abstract

PURPOSE: To largely increase the dehydrating efficiency of sludge by providing a high-pressure dehydrating portion using an auxiliary belt in the end portion of the joining-dehydration section of two sets of filter cloth belts circulating endlessly.
CONSTITUTION: In the filtration of sludge by two sets of filtering cloth belts 1a and 1b circulating in endlessly, sludge is supplied onto the filtering cloth belt 1a at a sludge-supplying position 2 and dehydrated by gravity by means of the filtering cloth 1a in an area to reach a joining-starting point A, ane then the filtering clothes 1a and 1b are joined at the joining point A so as to put sludge between them and also to make it go in zig-zag between a large number of facial pressure-generating rollers 3, whereupon a shearing and compressive force is applied on the sludge for dehydration. At the end portion B of the joining-dehydrating section, high-pressure roller 4 and rollers 5 and 5' to hang the belt on the roller 4 on the form of Ω are provided and at the same time, the joined filtering cloth belts are pressed on the roller 4 by an auxiliary belt 6 to sufficiently dehydrate the sludge by strongly press the sludge in the joined belts. Thus, the dehydrating efficiency of sludge cake can be largely increased.
