Abstract

Dispositivo per il pretrattamento di rottami di circuiti elettronici, comprendente un condotto disposto ad una certa inclinazione sulla verticale, nel quale sono disposte giranti a griglia controruotanti in cascata dall'estremità superiore, di ingresso dei rottami, all'estremità inferiore, di uscita dei rottami. I mezzi di ingresso e di uscita dei rottami sono costituiti da porte girevoli rispettive e da una bocca di carico e da un convogliatore di scarico rispettivamente, con interposizione, secondo una variante dell'invenzione, di rispettive barriere d'aria. Il condotto è dotato di mezzi per la circolazione al suo interno di fluido di scambio termico dall'estremità inferiore all'estremità superiore.Costituisce oggetto dell'invenzione anche un procedimento per il pretrattamento di rottami di circuiti elettronici, comprendente gli stadi di: (I) trattamento in un forno costituito da un dispositivo secondo l'invenzione; (II) trattamento di plastiche e metalli in un refrigeratore costituito da un dispositivo secondo l'invenzione, nonché (III) bruciatura dell'aria in uscita e (IIII) bruciatura del fluido di scambio termico in uscita.
