Patent ID: 6874644

Claim:
An appliance for material separation having a container ( 10 ), which comprises at least one sedimentation chamber ( 12 ) for accepting and sedimenting a material, which is bounded at one end by a base ( 14 ) which has an opening ( 16 ) for evacuating a sedimented material, a flow device for supplying a washing liquid being provided in the container ( 10 ), characterized in that the opening ( 16 ) in the base ( 14 ) of the sedimentation chamber ( 12 ) is configured as a gap by means of which a continuous sediment film can be generated during the evacuation of the sedimented material, and the flow device comprises at least one duct ( 18 , 20 ), which is arranged in a region of the outlet of the sediment film from the gap and is configured for the approach flow of the washing liquid through the sediment film, the gap in the base ( 14 ) of the sedimentation chamber ( 12 ) having an annular configuration in order to form ad annular sediment film, and wherein an inner duct ( 20 ) is arranged as feed duct within the annular sediment film and in that the flow device has an annular outer duct ( 18 ) as evacuation duct, which surrounds the annular sediment film and is configured for evacuating the washing liquid which flows through the sediment film.
