ABSTRACT:
A drum vacuum filter is shown which draws-in and radially outwardly projects the liquid content of a slurry or the like while the latter is advanced vertically along a passageway defined between a cylindrical rotating filter and a rotating drum wall, the latter of which collects and advances the solid material content of the slurry downwardly along the passageway for delivery and, as facilitated by a scroll scraper extending therealong. The liquid content is drawn under vacuum pressure induced force by a series of spaced-apart flutes or plates disposed along the exterior of the rotating filter, and radially or transversely outwardly with respect to the filter for segregated delivery with respect to the solid material content of the slurry or changed-in liquid.
