Patent ID: 7204795

Claim:
A self-discharging centrifuge ( 1 ) for the process engineering treatment of highly concentrated pastes, comprising at least a housing ( 10 ) that is optionally coolable, a feed line ( 11 ) for a suspension, a discharge line ( 12 ) for a clarified liquid, a suspended drum ( 14 ), which is connected to a drive part ( 13 ) at the top and has two or more discharge slots ( 3 ), and a collection vessel ( 7 ), wherein the centrifuge ( 1 ) includes a paste deflector ring having an annular impact wall ( 2 ) for the self-discharging centrifuge ( 1 ), said centrifuge having a discharge slot ( 3 ), wherein a setting angle α of the tangent of the impact wall ( 2 ) of the paste deflector ring ( 4 ) positioned opposite the discharge slot ( 3 ) of the centrifuge ( 1 ) with respect to the horizontal is from 3 to 60° as seen over the entire opening width of the discharge slot ( 3 ), said paste deflector ring having an inner contour immediately below the impact wall of circular or parabolic design and, in the region below said discharge slot ( 3 ) a curved inner contour with a radius of curvature (r) of>20 mm, said impact wall ( 2 ) having, in the region above the opening width of the discharge slot ( 3 ), a setting angle γ with respect to the horizontal of 3 to 30°, the tangent of the inner contour, in the region below the curved inner contour of the paste deflector ring having a setting angle β of up to 30°, with respect to the vertical, said paste deflector ring ( 4 ) having, at its lower end, a detachment edge ( 6 ) which optionally is undercut, said paste deflector ring ( 4 ) being integral with said collection vessel ( 7 ) or detachably connected to said collection vessel, said paste deflector ring being provided with a cooling jacket ( 8 ).
