Abstract

Eine Vollmantelzentrifuge (1) zum Entwässern von Schlamm, bestehend aus einer konischen Vollmanteltrommel (2) und einem dazu mit Rela­ tivdrehzahl drehenden Innenrotorteil (3), das Einrichtungen (15, 16) zum Axialtransport der festen Schlammbestandteile aufweist, wobei der Schlammeintrag (14) im konisch verjüngten Ende und der Austrag der festen Schlammbestandteile am konisch erweiterten Ende der Vollmanteltrommel (2) erfolgt, soll dahingehend verbessert werden, daß bei Verringerung des Energieaufwandes eine verbesserte Trennwirkung erzielt wird. Hierzu wird vorgeschlagen, daß der Schlammeintrag über einen oder mehrere radiale Schlammein­ trittskanäle (14) erfolgt, die Einrichtungen zum Axialtransport aus am Innenrotorteil (3) befestigten Flächenelementen (16) bestehen, die in geringem Abstand an der Innenwandung der Vollmanteltrommel vor­ beibewegbar sind und die an Halterungen (15) gehalten sind, durch die mindestens zu 50 % des radialen Abstandes zwischen der Wan­ dung des Innenrotorteils (3) und der Innenwandung der Vollmantel­ trommel (2) ein von den Flächenelementen (16) freier axialer Durch­ trittskanal gegeben ist, am konisch erweiterten Ende der Voll­ manteltrommel (2) am Innenrotorteil (3) eine Stauscheibe (17) befestigt ist, die zur Innenwandung der Vollmanteltrommel (2) unter Bildung eines Ringspaltes (18) angeordnet ist, der die Durchtrittsöffnung von einem vor der Stauscheibe (17) befindlichen Kompaktierungsraum (19) zu einem hinter der Stauscheibe (17) befindlichen Sedimentaustragsraum (20) darstellt, aus dem einer oder mehrere radial nach innen gerich­ tete Sedimentaustrittskanäle (29) führen, die an einen das Sediment nach außerhalb der Vollmanteltrommel (2) leitenden Sedimentaus­ tragskanal (25) anschließen, wobei die vom Sediment getrennte Flüs­ sigkeit aus dem Kompaktierungsraum (19) durch einen oder mehrere in den Klarbereich der Flüssigkeit mündende Flüssigkeitsaustritts­ kanäle (28) ausgetragen wird, die am Innenrotor (3) radial nach innen verlaufend angeordnet sind und in einen die Flüssigkeit nach außerhalb der Vollmanteltrommel (2) leitenden Flüssigkeitsaustrags­ kanal (29) übergehen. A solid bowl centrifuge (1) for dewatering sludge, consisting of consisting of a conical solid jacket drum (2) and one with a relay tivdrehzahl rotating inner rotor part (3), the devices (15, 16) for Axial transport of the solid sludge components, wherein the sludge entry (14) in the tapered end and the discharge the solid sludge components at the flared end of the Solid drum (2) takes place, should be improved in that that with a reduction in energy consumption an improved Separating effect is achieved. It is proposed that the Sludge entry via one or more radial sludges occurs through channels (14), the devices for axial transport on the inner rotor part (3) attached surface elements (16) exist in short distance on the inner wall of the solid jacket drum are movable and which are held on brackets (15) by which is at least 50% of the radial distance between the tub the inner rotor part (3) and the inner wall of the solid jacket drum (2) of the surface elements (16) free axial through is given at the conical end of the full jacket drum (2) on the inner rotor part (3) a baffle plate (17) is attached, to the inner wall of the solid casing drum (2) to form a     Annular gap (18) is arranged which the passage opening of a compacting space (19) located in front of the baffle plate (17) a sediment discharge space (20) located behind the baffle plate (17) represents one or more radially inward tete sediment outlet channels (29) lead to the sediment to the sediment conducting outside the solid jacket drum (2) Connect the supporting channel (25), the rivers separated from the sediment liquid from the compacting space (19) by one or more in liquid outlet opening into the clear area of the liquid channels (28) is carried out on the inner rotor (3) radially inwards are arranged in a gradient and into the liquid outside the solid jacket drum (2) conductive liquid discharge pass over channel (29).
