Abstract

Un apparecchio di separazione per materiale di piccole dimensioni comprende una vasca di separazione (1) che può essere riempita di liquido fino ad un livello (L) predeterminato, un dispositivo (3) a ciclone idraulico per l'introduzione del materiale congiuntamente ad un liquido convettivo nella vasca (1) al di sotto di detto livello predeterminato con una pressione superiore a quella esistente nell'area d'ingresso dovuta al peso della massa del liquido contenuto nella vasca stessa e un primo ed un secondo mezzo d'espulsione di materiale dalla vasca (21, 24) collocati, rispettivamente, al detto livello predefinito ed in fondo alla vasca (1) per l'asportazione, rispettivamente, del materiale avente peso specifico minore e maggiore di quello del liquido contenuto nella vasca stessa. (Fig. 1)A separation device for small material includes a separation tank (1) which can be filled with liquid up to a predetermined level (L), a hydraulic cyclone device (3) for introducing the material together with a liquid convective in the tank (1) below said predetermined level with a pressure higher than that existing in the inlet area due to the weight of the mass of the liquid contained in the tank itself and a first and a second means for expelling material from the tank (21, 24) located respectively at said predefined level and at the bottom of the tank (1) for the removal, respectively, of the material having a specific weight lower and greater than that of the liquid contained in the tank itself. (Fig. 1)
