摘要

Screw conveyor device (10) or hydroelectric screw device, comprises a drivable central axis of rotation, a screw conveyor profile connected to the rotational axis, a drive unit for the axis of rotation or the screw conveyor profile and/or a generator unit coupled with the rotary axis unit, a trough profile partially surrounding the screw conveyor profile and a heat exchanger (20, 20.1), which is directly or indirectly contacted in a thermally-conductive manner with the pumped liquid. An independent claim is also included for the sewage treatment plant or a pumping station for the transportation of waste water, comprising a screw conveyor device arranged in the waste water supply system and/or waste water drainage system of the sewage treatment plant or pumping station.
