Abstract
A solid-jacket screw centrifuge is disclosed. The centrifuge has a rotatable drum with a horizontal axis of rotation which encloses a bowl with a rotatable screw, an inlet for introducing material to be centrifuged into the bowl, at least one liquid and at least one solid discharge, where at least the solid discharge is assigned a non-rotatable housing surrounding it, at least radially bounding a discharge chamber, where the discharge chamber is designed as a drying chamber for the solid matter and has axial walls and one or more walls in the radial direction. The housing extends axially parallel to the axis of rotation at most into the conical region of the drum or the screw.
Claims16
A solid-jacket screw centrifuge, comprising:
- a rotatable drum with a horizontal rotational axis, wherein the rotatable drum surrounds a centrifuge chamber with a rotatable screw;
- an inlet for introducing a suspension to be centrifuged into the centrifuge chamber;
- and
- a liquid discharge and a solid matter discharge;
- wherein at least the solid matter discharge has assigned thereto a non-rotatable housing which surrounds the solid matter discharge and delimits a discharge chamber at least radially;
- wherein the discharge chamber is a drying chamber for solid matter, wherein the drying chamber has axial walls and a radial wall;
- wherein the housing extends axially parallel to the rotational axis no further than into a conical region of the drum or of the screw;
- wherein load-bearing elements of a machine frame structure extend through an interior of the housing.
