Claims (15)
1. Förfarande för diskontinuerlig filtrering av suspensioner genom utifrän verkande presstryck i en detta tryck skapande presskammare eller liknande, kännetecknat därav, att efter press-ningen av suspensionen (R) i presskammarrummet (12) och före inträ-det av den uppkomna presskakan (R^) i ätminstone ett efterföljan-de presskammarrum (12^, 12n) strukturen av presskakan förändras me<-delst sjuvkrafter.
2. Förfarande enligt patentkravet 1, kännetecknat därav, att den uppkomna presskakan (R^) böjes och ätminstone delvis sönder-rives mellan presskamrarna (3, 4, 5).
3. Förfarande enligt patentkravet 2, kännetecknat därav, att presskakan (Rj^) böjes ät tvä häll, dvs. i motsatta riktningar, mellan presskamrarna (3, 4, 5).
4. Förfarande enligt nägot av patentkraven 1-3, kännetecknat därav, att presskakan tilltar i en presszon gentemot den före-gäende presszonen, särskilt utövas ett större presstryck i en presskammare (5 resp. 4) än i den föregäende presskammaren (4 resp. 3).
5. Förfarande enligt nägot av patentkraven 1-4, för avvattning av kommunalslam, kännetecknat därav, att det flockade slam-met pressas i en första presszon (12) med längsam tryckökning och ett tryck av upp tili ca 100 KPa och i ätminstone en efterföljande presszon (12^) utsättes för en i förhällande tili den första presszonen relativt snabb tryckökning upptill en tryck av ca 300 KPa.
6. Förfarande enligt patentkravet 5, kännetecknat därav, att slammet pressas i en ytterligare presszon (12n) vid förhällande-vis snabb tryckökning upp tili ca 1000 KPa. 66760
7. Anordning för diskontinuerlig filtrering av suspensioner genom utifrän verkande presstryck i en detta tryck skapande presskammare av ätminstone delvis pä föränderligt avständ till varandra anordna-de pressytor eller liknande, kännetecknad av ätminstone tvä efter varandra anordnade presskammarrum (12) samt av ätminstone tvä för dessa rum gemensamma, suspensionen (R) mellan sig upptagande, förflyttade filtermedier, exempelvis filterdukar (20, 21), vilka löper ungefär parallellt med pressytorna (1, 2) och mellan press-kamrarna är förda över en krökt yta (22).

Anordning enligt patentkravet 7, kännetecknad där-av, att den krökta ytan Sr bildad av mantelväggen för en bryttrumma (22) och att efter denna trumma eventuellt ätminstone en ytterligare bryttrumma är anordnad pä sädant sätt, att filterdukarna (20, 21) delvis omsluter bryttrummorna i tvärsnitt ungefär meanderformigt.
9. Anordning enligt patentkravet 7 eller 8, kännetecknad därav, att en fast pressplatta och en gentemot denna platta avständs-föränderlig pressplatta (1, 2) tjänar som pressytor vid presskamma-ren (12) .
10. Anordning enligt patentkravet 9, kännetecknad därav, att den rörliga pressplattan (2) är förbunden med mekaniska tryck-organ, företrädesvis med hydrauliska eller pneumatiska presscylind-rar (7, 8) .
11. Anordning enligt nägot av patentkraven 7-10, kännetecknad därav, att ätminstone en pressyta vid presskammaren (12) bildas av ett membran eller en motsvarande, elastisk yta (lm, 2m), som är sä utformade, att de under inflytande av ett spännmedium, speciellt tryckluft eller tryckvätska, tidsvis kan förändra sin form.
12. Anordning enligt nägot av patentkraven 7-11, kännetecknad av ändlösa filtermedier (20, 21) eller -band, som är drivbara med eventuellt olika hastigheter.
13. Anordning enligt nägot av patentkraven 7-12, kännetecknad därav, att filtermedierna (20, 21) är lagda över brytrullar (23) eller liknande och före den första presskammaren (3) bildar en inloppstratt (24) eller liknande.
