ABSTRACT:
The apparatus is a washer, thickener and classifier for recovering solids from liquids including a truncated conical screen with walls typically sixty degrees from the horizontal and formed of filter media. Stock sprayer assemblies rotate about a longitudinal axis of said conical screen and direct stock, particularly deink paper stock, onto the walls of the conical screen. Wash fluid sprayer assemblies, including high impact shower nozzles, direct wash fluid onto the stock on the walls of the conical screen. The wash fluid cleans the stock, with the unwanted solids and contaminants passing through the conical screen to the discharge pipes. The wash fluid similarly washes the cleaned stock through the exit formed at the truncated portion formed at the apex of the conical screen for subsequent processing.
