Abstract
Abstract Extraction apparatus wherein solid and liquid phases are subjected to vibro-acoustical action in order to intensify the extraction process. The apparatus includes an enclosure forming a working perforated vessel, spring means mounting such vessel for vibratory movement, a vibrator mounted on the vessel to vibrate it, two laterally displaced feeding openings for receiving, respectively, solid particulate material and liquid, two spaced discharge outlets on the cell for discharging, respectively, solid material and liquid.

Claim 1
Independent Claim
191 words
An apparatus for extraction, comprising in combination, an enclosure forming a working cell with imperforate walls; spring means mounted on said working cell; a vessel having perforated side walls mounted on said spring means inside said working cell for vibratory movement, said vessel forming an independent chamber within said working cell; a vibrator mounted on said vessel and adapted to impart to said vessel a vibratory movement; said working cell having a first, outlet conduit for discharging fluid from said working cell and said vessel having a second, inlet conduit extending through the wall of said working cell and the perforated side wall of said vessel for feeding liquid into said vessel; an upwardly inclined pulp discharge conduit means leading from the bottom of said cell to a raised discharge orifice; said pulp discharge conduit being dimensioned to discharge pulp above the level of the lowest point of said vessel. a solid material discharge conduit means connected to said cell adjacent to the bottom thereof; a feeding solid material conduit mounted on the top of the vessel; and a selectively operable shut-off valve operatively mounted on said solid discharge conduit means.
