Abstract

Oggetto dell'invenzione è un dispositivo per il lavaggio di fanghi a contenuto metallico, comprendente un cilindro coclea, con pale interposte tra le spire, sostenuto girevolmente in entrambi i sensi sul suo asse in orizzontale in un cilindro fisso contenente un fluido di lavaggio, fatto circolare tra l'interno del cilindro coclea e l'intercapedine tra questo ed il cilindro fisso. Il fluido di lavaggio esaurito viene allontanato e sostituito nel cilindro fisso da fluido di lavaggio vergine, sotto la regolazione di un comando di livello. Il cilindro coclea viene fatto girare nei due versi, facendo andare in avanti e all'indietro, incontrando il fluido di lavaggio, il fango da lavare nel suo interno, secondo un programma di lavaggio predeterminato, realizzato il quale il fango, lavato, viene allontanato dopo filtrazione.Costituiscono oggetto della presente invenzione anche un procedimento per il lavaggio di fanghi a contenuto metallico, facente uso di tale tipo di dispositivo, ed un prodotto atto a combattere l'eccessiva acidità di terreni boschivi, costituito dal fango residuo di tale procedimento.
