Description
PATENTKRAV 1. Dekantercentrifuge til separering af et tilført materiale i en let fase (12) og en tung fase (13), omfattende en til rotation om sin længdeakse indrettet langstrakt tromle (2) med et separationskammer, en i separationskammeret beliggende og med tromlen koaksial snegletransportør (3) omfattende en krop (4) , der bærer en en eller flere gænger (7, 7') omfattende snegl med en langs længdeaksen (20) varierende nominel transporthastighed, et indløb med mindst en indløbsåbning (6) i snegletransportøren til tilførsel af materialet, der skal separeres, og mindst en afgangsåbning (14) for den tunge fase i tromlen ved sneglet ransportørens (3) ene ende, hvor snegletransportøren er indrettet til at rotere i forhold til tromlen (2) med henblik på at transportere den tunge fase mod afgangsåbningerne (14) for den tunge fase, og hvor snegletransportøren har en mellem indløbsåbningerne (6) og afgangsåbningerne (14) beliggende baffel (8, 8'), der opdeler separationskammeret i en i det væsentlige cylindrisk separationsdel (17) og en i det mindste delvis konisk afgangsdel (18) , hvorved afgangsåbningerne (14) for den tunge fase er beliggende i afgangsdelen (18) , og indløbsåbningerne (6) er beliggende på den modsatte side af baflen (8) i forhold til nævnte afgangsåbninger, kendetegnet ved, at der umiddelbart opstrøms for baflen (8, 8'), i forhold til transportretningen, er en overgangsdel (19) mellem separationsdelen (17) og afgangsdelen (18) , og at snegletransportøren (3) har en større nominelle transporthastighed i overgangsdelen (19) end i separationsdelen (17) umiddelbart før overgangsdelen (19), idet ændringen i sneglens nominelle transporthastighed fra den nominelle transporthastighed i separationsdelen umiddelbart før overgangsdelen til den højere nominelle transporthastighed i overgangsdelen er tilvejebragt ved en ændring (21) af sneglens stigning. 2. Dekantercentrifuge ifølge krav 1, kendetegnet ved, at ændringen (21) i sneglens stigning er brat. 3. Dekantercentrifuge ifølge krav 1, kendetegnet ved, at ændringen i sneglens stigning er gradvis. 4. Dekantercentrifuge ifølge krav 1-3, kendetegnet ved, at sneglens stigningsvinkel i separationsdelen (17) er væsentligt mindre end 45° i forhold til tangentielretningen og at ændringen (21) i sneglens stigning er en forøgelse. 5. Dekantercentrifuge ifølge krav 4, kendetegnet ved, at den nævnte forøgelse er 40-80%. 6. Dekantercentrifuge ifølge krav 1-3, kendetegnet ved, at sneglens stigningsvinkel i separationsdelen (17) er væsentligt større end 45° i forhold til tangentielretningen og at ændringen (21) i sneglens stigning er en formindskelse. 7. Dekantercentrifuge ifølge krav 1-6, kendetegnet ved, at sneglen har den større nominelle transporthastighed over i det mindste en 1/3 x 1/n af en vinding før baflen (8), fortrinsvis over ca. 2/3 x 1/n af en vinding, hvor n er antallet af gænger (7, 7' ) . 8. Dekantercentrifuge ifølge krav 1-7, kendetegnet ved, at indløbet (6) er placeret opstrøms for overgangsdelen (19) i separationsdelen (17) . 9. Dekantercentrifuge ifølge krav 1-8, k e n - detegnet ved, at baflen (8) har en aksial udstrækning, hvorved grænsen mellem afgangsdelen og overgangsdelen er beliggende ved midtpunktet (23) for baflens aksiale udstrækning. 10. Dekantercentrifuge ifølge krav 1-9, kendetegnet ved, at sneglens stigning er voksende i separeringsdelen (17) i retning væk fra overgangsdelen (19) .
