DISPOSITIVO DI FILTRAZIONE CONTINUA E SOTTO PRESSIONE DI SOSTANZE SOLIDE CONTENUTE IN LIQUIDI

摘要

Continuous filtration under pressure is obtained by combination of a looped filter belt and an alveolar belt which are caused to cooperate with a rotary distributor drum. The belts are compressed against the drum through application onto the belts of an external pressure which is at least equal to the filtration pressure but which is exerted on a surface which is larger than that onto which the filtration pressure is exerted.
