  1. SKRUEPRESSE OG ANVENDELSE AF SKRUEPRESSEN TIL AFVANDING AF SLAM PATENTKRAV
    1. Skruepresse (100) til afvanding af slam med tre efter hinanden placerede filtre til afvanding, hvilken skruepresse indbefatter et drænfilter (4), et filtreringsfilter (5) og et søjlefilter (6), og som ligeledes indbefatter en modtryksanordning (7) til frembringelse af et tryk inde i filtrene, og som endvidere har en indgang (1) til tilførsel af slammet til skruepressen, en udgang (9), en snegl (2), der er anbragt inde i filtrene, til tilførsel af slammet gennem tilførslen mod udgangen (9), kendetegnet ved, at indgangen (1) omfatter en cylindrisk rørsektion (15) med endeflanger (16A, 16B), hvilke endeflanger (16A, 16B) er forsynet med en flerhed af huller (17), og hvor den cylindriske rørsektion (15) endvidere er forsynet med et indgangsrør (19), hvilket indgangsrør (19) er forbundet med den cylindriske rørsektion (15) via et åbningshul (18) i sidevæggen af den cylindriske rørsektion (15), hvor indgangen (1) er fleksibelt anbragt i forhold til resten af skruepressen, hvilket gør det muligt at justere indgangen (1) til et rørsystem, der er forbundet med skruepressen (100), og hvor indgangens (1) cylindriske rørsektion (15) er forsynet med et endestykke (14).
  2. 2. Skruepresse (1) til afvanding af slam ifølge krav 1, hvor hullerne (17), der er anbragt på endeflangerne (16A, 16B), gør det muligt at rotere indgangen (1) i forhold til resten af skruepressen (100).
  3. 3. Skruepresse (1) til afvanding af slam ifølge krav 2, hvor indgangsrøret (19) er bøjet 90 grader fra en første ende forbundet med indgangen (1) til en anden fri ende.
  4. 4. Skruepresse (1) til afvanding af slam ifølge krav 3, hvor indgangsrøret (19) er forsynet med en flange (13) i den frie ende til tilkobling til et rørsystem.
  5. 5. Anvendelse af skruepressen (100) ifølge et eller flere af kravene 1 til 4 til afvanding af slam indbefattende materiale i flydende tilstand.
