Abstract
Official abstract text for this publication.
A separator arrangement includes a drum with a vertical axis and which is rotatably mounted in a hooded area and placed on a rotatable drive spindle. The arrangement also includes a sealed drive area containing one or more or all of the components of a separator drive, and a pump that generates negative pressure in the sealed drive area relative to the surroundings outside of the drive area.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for operating a separator, the method comprising: rotating a rotatable drum arranged in a hooded chamber, wherein the rotatable drum has a vertical rotational axis and is arranged on a rotatable drive spindle; generating, by a pump, in a sealed drive chamber including one, several or all components of a separator drive, negative pressure in the sealed drive chamber in relation to a surrounding area outside the sealed drive chamber; and generating negative pressure in the hooded chamber, wherein the negative pressure in the hooded chamber is modified in dependence on an operating state of the separator and wherein the operating state is a solid matter ejection from the rotatable drum; wherein the negative pressure in the hooded chamber is increased prior to or during the solid matter ejection from the rotatable drum and is lowered from the increase after the solid matter ejection.
