The device comprises a filter unit in which the filtering element consists of a continuous tape (13) made of fibrous material that passes through the filter unit (5; 100) to intercept with one or more portions of its extension the liquid to be filtered. The device can also comprise: a pair of motorized drive rollers (31, 37) of the tape (13) suitable to feed it when one or more tape portions require to be replaced. The pair of rollers (31, 37) is positioned downstream of the filter unit (5; 100). There can also be provided thrust means (39, 35) that elastically stress the rollers to press the spent tape (13) therebetween, expelling the liquid that impregnates it; and collection means (51; 115) of the liquid thus extracted.
