Abstract

Fremgangsmåte og anordning for gjenvinning av hovedsakelig ren sand fra en varmebehandlingsovn (19) , hvor et støpestykke med vedheftet sandkjerne og/eller sandform, omfattende sand bundet av et bindemateriale som kan forbrennes, innføres i varmebehandlingsovnen, eller hvor deler av sandkjerne og/eller sandform som ikke er vedheftet et støpestykke innføres i varmebehandlingsovnen. Idet gjenvinningen i ovnen utføres delvis v.h.a. en sveveinnretning (som f.eks., men ikke begrenset til, en sikt (252) eller fluidiserer (40)) som fremmer forbrenning av bindemateriale v.h.a. én eller flere av prosessene omrøring, oppvarming og oksydering. Idet karakteristikaene til den gjenvundne sand styres selektivt ved å styre sandens oppholdstid i varmebehandlingsovnen.Method and apparatus for recovering substantially pure sand from a heat treating furnace (19), wherein a casting piece with an adhered sand core and / or sand mold, comprising sand bound by a combustible bondable material, is introduced into the heat treating furnace, or wherein parts of the sand core and / or sand mold which is not adhered to a casting insert is introduced into the heat treatment furnace. As the recycling in the furnace is carried out partly by a floating device (such as, but not limited to, a screen (252) or fluidizer (40)) which promotes combustion of binder material by e.g. one or more of the processes stirring, heating and oxidizing. As the characteristics of the recovered sand are selectively controlled by controlling the residence time of the sand in the heat treatment furnace.
