Solid-jacket screw centrifuge

Abstract

Solid-jacket screw centrifuge (1) for processing a suspension Su in a centrifugal field, comprising at least the following: a. a rotatable drum (210) with an axis of rotation (D), wherein the drum (210) has a cylindrical section (211) and a conical section (212) and a separation chamber (219), b. a screw (230) arranged in the drum (210) and rotatable at a differential speed relative to the rotatable drum (210), c. an inlet pipe (217) through which the suspension Su to be processed can be conveyed into a separation chamber (219) of the drum (210), d. at least one liquid discharge (214) arranged in the cylindrical section (211) of the drum (210), and e. at least one solid discharge (216) arranged in the conical section (212) of the drum (210), f. wherein a device (240) for hydrohermetic sealing of the separation space (219) is associated with the separation space (219), characterized in thatThe discharge of the liquid phase Fl from the separation chamber (219) is carried out with a peeling device (215) which has an inlet opening (2153) that is located in the radial direction on an inlet radius RE, wherein the inlet radius RE is variable in the radial direction.
