US 4,417,980 A · Filtration apparatus

Abstract

A filtration apparatus comprises a tiltably mounted container having a liquid permeable filter bottom, a wall opposite such bottom, and an inverted neck extending inwardly from that opposite wall. A power shaft extends through the inverted neck into the container and carries a mixing implement in the container. A guide bearing for the power shaft is located in the inverted neck. A drive for the mixing implement is supported on the container wall opposite the filter bottom for driving the power shaft. A lifting mechanism connected to said power shaft is also supported by that opposite wall for axially displacing the power shaft and mixing implement in said container. A support bearing at one side of the container and the frame has an apertured part rotatable with the tiltable container. Conduits are conducted through the apertured part for angular movement with the container, thereby avoiding a tangling of lines.
