Abstract

Dispositivo di scarico per filtro-pressa prevede mezzi di supporto superiori di una serie di tele filtranti associate alle superfici frontali opposte di una corrispondente serie di piastre disposte a pacco e atte ad essere serrate fra una testata fissa e una testata mobile, in maniera da formare una successione di camere di filtrazione nelle quali viene alimentato il liquido da filtrare. Tali mezzi di supporto sono mobili verticalmente fra una posizione sollevata di filtrazione, in cui le tele filtranti risultano in tensione, e una posizione abbassata di scarico, in cui una porzione superiore di dette tele forma una piega atta a favorire il distacco delle mattonelle formate dai residui solidi di filtrazione. La posizione di scarico è ottenuta in combinazione con una limitata apertura di dette camere di filtrazione.
