FILTER ASSEMBLY WITH FILTRATE FLOW CONTROL AND CONTROL COMPONENTS

摘要

Disc filter assembly in which a plurality of filter discs are mounted on common shaft for rotation to selectively dispose disc surfaces under vacuum in a confined body of slurry through a portion of said rotation and to discharge formed cake from said surfaces by "blow" action through another portion of rotation. Each disc has plurality of sectors in sequential arrangement circumferentially of shaft mounted on a hollow center shaft fabricated from standard industrial components, inclusive of steel pipe forming shaft exterior and plurality of tubular members of oblong section in welded circumferentially spaced arrangement interiorly of pipe providing a conductive passage in communicating relation to at least one sector for applying vacuum and blow thereto under control of filter valve.
