Abstract

A rotary separator has a separation vessel comprised of opposed conical sections and has an annular gap between the sections for discharge of solid material. A sleeve surrounds the separation vessel and is attached to the lower conical section thereof by a flexible member allowing axial sleeve movement. The sleeve carries a ring for comovement therewith displaceable to open and close the gap. When the pressure of material in the vessel is sufficient to overcome the flexibility characteristics of the material supporting the sleeve, discharge occurs. The flexible member may be pre-stressed to control the pressure required for discharge to occur, or a chamber communicating with the sleeve and flexible member may be pressurized to selectively displace the sleeve and ring and thereby control discharge.

Claims6

Dependent claims

A separator for separating materials of different densities consisting of:

a rotational-symmetric separation vessel having at least one discharge aperture disposed on a circumference thereof;
an annular sleeve spaced from said separation vessel and forming a piston valve in cooperation therewith having a chamber which is chargeable with a pressure medium and which surrounds the exterior of the separation vessel and normally blocks said discharge aperture;
a flexible connection element radially attached between the sleeve and the separation vessel, said connection element permitting limited uniform axial displacement of and guiding said sleeve to open and close said aperture, said connection element further having a selected flexibility to normally oppose interior pressure developed in said separator and to allow piston valve displacement and material discharge upon developement of a selected interior pressure.
