Improvements in vacuum Belt Filters, especially - to the liquid separation of Aqueous suspensions

摘要

Installation for Separation of Liquids in aqueous suspensions by means of Belt Vacuum Filter. The Conveyor Belt (1) comprises a support Mesh like structure is arranged on the filter Fabric (9), of Greater width than the supporting structure, so there are some marginal areas (9a).In the vacuum Chamber (16) the marginal areas of the filter Fabric (9a) Sliding on the formacioneslaterales (23), ensuring the tightness longuitudinal. The transverse Sealing is achieved through the use of pressure Rollers mounted on the tape at the ends of the vacuum Chamber.These cylinders are formed by a rigid Tube covered by a Resilient Sleeve of cellular Rubber or similar material. The Sealing Cylinder are mounted so that their surfaces are in contact with the Inner Faces of the walls to ensure tightness.
