Abstract
L'invenzione realizza un dispositivo di filtrazione per la separazione dei materiali inquinanti da masse plastiche fuse in presse per l'estrusione di materiali plastici riciclati ove dette presse comprendono almeno un estrusore (2) provvisto di almeno una coclea rotante (3) di spinta del materiale e di almeno una testa di estrusione (4) provvista di una filiera di estrusione (5). Il dispositivo di filtrazione (1) comprende almeno un filtro (6) disposto in corrispondenza di detto almeno un estrusore (2) ed almeno un raschiatore (11; 21; 31) che ruota a contatto con la superficie di detto almeno un filtro (6) essendo calettato ad una di dette almeno una coclea rotante (3).
