Abstract
A suction-filter-drier, in particular for isolating and drying a product from suspension, comprising a closed container having an outer wall and a horizontal axis and including a liquid permeable filter positioned in the container and spaced from the outer wall; and having a plurality of filter chambers disposed between the filter means and the outer wall; and further including a hollow rotatable rotor extending axially through the container with the rotor being oblate in cross-section with a rotor disc supported on the rotor, and including means for selectively oscillating the rotor by imparting a reversely pivoting motion.
Claims41
A suction-filter-drier, in particular for isolating and drying products from suspension characterized by a closed container (1) having a horizontal axis, of which the casing comprises generally in its lower half a liquid-permeable, concave, for instance cylindrically or elliptically curved inner filter surface (24) and an outer wall (42) spaced from this surface, this casing being divided into a plurality of filter chambers (11 through 15), and by a hollow rotor (54) generally extending axially through the container and supporting heatable rotor disks means (58) and driven in swinging or in reversible rotating manner to homogenize the product cake during filtration or to wash and to dry the product following isolation and said filter surface (24) operable through a manifold system communicating with the filter chambers (11 through 18) and through selectively connected vacuum or compressed-gas sources both with excess pressure in the container (1) and external vacuum on one hand and on the other with external excess pressure and vacuum or normal pressure in the container.
A suction-filter-drier, in particular for isolating and drying a product from suspension, comprising:
- (a) a closed container comprising an outer wall, said container having a horizontal axis;
- (b) a liquid permeable filter means positioned in said container and spaced from said outer wall;
- (c) a plurality of filter chambers disposed between said filter means and said outer wall;
- (d) a hollow rotatable rotor extending axially through said container, said rotor being oblate in cross section;
- (e) rotor disk means supported on said rotor;
- and
- (f) means for selectively oscillating said rotor by imparting a reversely pivoting motion thereto so that a product in said container becomes compacted.
