Problems solved by technology

At the same time, however, the tank depth is limited by the diameter of the worm hub and the buoyancy and sedimentation effects of the mixture to be clarified or light phase obtained there.
[0004] The diameter of the worm hub cannot be reduced indefinitely, as this would negatively affect the stiffness of the worm and its stability

Embodiment Construction

[0026] In these figures a full shell worm centrifuge 10 is shown which extends substantially along a horizontal longitudinal axis 12 . The full-shell worm centrifugal separator 10 has an outer housing 14 in which a drum 16 is mounted rotatably about a longitudinal axis 12 . By rotating the drum 16 at a high rotational speed, a centrifugal force can be generated in the drum by means of which the substance to be clarified can be separated into a heavy phase and a light phase. The roller 16 is supported for this purpose on a first roller bearing 18 and a second roller bearing 20 .

[0027] An inlet 22 for the substance to be clarified as well as an outlet 24 for the heavy phase and an outlet 26 for the light phase are formed on the drum 16 . A drive 28 is provided for rotating the drum 16 . The outlet 26 serves as an overflow for the light phase located radially inwardly in the drum 16 , so that it flows out there automatically as soon as a predetermined liquid level, the so-ca...

Abstract

The invention relates to a screw (30) of a solid bowl centrifuge (10), comprising a screw hub (32) extending along a longitudinal axis (12), and a screw flight (34) surrounding the screw hub; the screw hub (32) is provided with a lattice structure (56) in a section (36) of the longitudinal extension thereof.

Description

technical field [0001] The invention relates to a worm of a full-shell worm centrifugal separator having a worm hub extending along a longitudinal axis and a worm screw surrounding the worm hub. The invention also relates to the application of this type of worm in a full-shell worm centrifuge. Background technique [0002] Full-shell worm centrifuges are characterized by a closed shell or full-shell drum. The drum rotates at a high rotational speed, whereby the multiphase mixture present in the drum can be separated into at least one heavy phase and a light phase. The heavy phase is generally the solid phase, which is conveyed out of the drum by means of a worm. For this purpose, the worm is rotatably mounted in the drum relative to the drum and has a worm screw which is arranged around a worm hub. The worm screw extends along the inner side or the inner shell surface of the drum and in this way conveys the heavy-phase material to an axial end region of the drum and conve...
