Abstract
Description
512 836 2 liknande flyter med vattnet, och eftersom detta material kan ha kan luft till- när så erford- olika vikt för överföringen till silorgan 10 och 11, föras medelst en anordning 9, som är placerad på en, ras, reglerbar, höj- och sänkbar anordning 8. Det överförda avlopps- vattnet, som nu är rent från tyngre partiklar, utgöres av lätta par- tiklar och dessa fastna på silorganen 10 och 11. Silorganen bestå av ett fast 10 och ett rörligt 11 organ innefattande delade stavar. Det fasta silorganet 10 eller gallret är försett med en sårad yta med utsläppning nedåt, medan det rörliga silorganet 11 eller gallret är utfört med hullingar utfällda vid nedgång för transport och infällda vid uppgång, när det fasta silorganet 10 har övertagit silningen. 512 836 2 similarly floats with the water, and since this material may have air, when necessary - different weight for the transfer to screen means 10 and 11, is conveyed by means of a device 9, which is placed on a, race, adjustable, height and submersible device 8. The transferred waste water, which is now clean of heavier particles, consists of light particles and these are attached to the screen means 10 and 11. The screen means consist of a fixed 10 and a movable 11 member comprising split rods. The fixed screen 10 or grid is provided with a wound surface with downward discharge, while the movable screen 11 or grid is made with barbs unfolded at the drop for transport and recessed at the ascent, when the fixed screen 10 has taken over the screen.
Det rörliga silorganet 11 eller gallret drives av ett drivorgan 13 och leder renset ned i en spiraltransportör 12, som har viss press- effekt för avskiljande av vatten och som bortför materialet under avvattning till lämplig upplagsplats, såsom t.ex. en container eller liknande.The movable screen means 11 or the grid is driven by a drive means 13 and leads the cleaner down into a spiral conveyor 12, which has a certain pressing effect for separating water and which removes the material during dewatering to a suitable storage place, such as e.g. a container or the like.
Uppfinningen är naturligtvis icke begränsad till detta utförande utan kan självklart varieras inom ramen för uppfinningstanken. ÄHThe invention is of course not limited to this embodiment but can of course be varied within the scope of the inventive idea. ÄH
