Abstract
In an apparatus for dewatering sludge the sludge to be dewatered is continuously fed to a pre-dewatering stage and is subsequently transferred to an enclosed sludge chamber volume, which is intermittently moved past stationary pairs of pressure-applying plates. The pre-dewatering stage is consituted by a stationary dewatering container which serves also as a buffer between the means for the continuous fooding of sludge and the means for a discontinuous and intermittent transfer of the sludge to the sludge chamber volume. Owing to that design the plant has a low structural expenditure and is operable at a high dewatering rate.
Claims56
Apparatus for dewatering sludge, comprising:
- a sludge feeding means for continuously feeding of the sludge to the apparatus, a sludge transfer means having a sludge chamber volume and pressure-applying plates for a discontinuous, intermittent transfer of the sludge for discharging the sludge from the dewatering apparatus and for applying high pressure to the sludge for dewatering the sludge, and a buffer means located between the sludge feeding means and the sludge transfer means, wherein the buffer means comprises a stationary container having a pre-dewatering stage which is continuously fed with the sludge to be dewatered and having one end of the container communicating with the sludge chamber volume, and wherein the buffer means is for substantially reducing the volume of the sludge prior to leaving the pre-dewatering stage.
