Abstract

En anordning for filtrering av et flytende medium som innbefatter en beholder (1) med innløp (2) for mediet. I beholderen er det anordnet en rotor (6) med en indre rotordel (7), og minst ett skive-lign- ende ytre filterelement (8) orientert i en vinkel mot den indre rotordelens (7) symmetriske akse. Filter- elementet oppviser en ytre filtrerende bekledning (10) og indre kanaler for å frakte filtratet som passerer gjennom bekledningen til en eller flere filtratkanaler (l 1) i den indre rotordelen (7). Midler (15) er framskaffet for å frigjøre materialet som er filtrert bort fra mediet og avsatt på filtrerings- bekledningen (10). Videre fins det midler (17) for bortføring av løsgjorte materialet. Disse bortfør- ingsmidlene er anordnet ved siden av filterele- mentet (8) for mottakelse av det fra dette løsgjorte materialet. Bortføringsmidlene (17) omfatter minst ett bevegelig transportorgan (35), som ved hjelp av et drivorgan (36) er drivbart for å forflytte det løsgjorte materialet vesentlig parallellt med filter- elementets utstrekning i en vinkel mot den indre rotordelens (7) geometriske akse. Dessuten omfatter oppfinnelsen en fremgangsmåte for å konvertere et trommelfilter til et skivefilter, hvorved trommel- filterets trommel erstattes med en skivefilterrotor med transportorgan av ovenfor diskuterte sort.
