Self-cleaning filtering device

Abstract

A filtering device for filtering particles, in particular plastic particles, such as plastic fibers, from liquid is configured to be operated in a filtering mode in which particles, in particular plastic particles, are filtered from a liquid flowing through the filtering device, the filtering device comprising an inlet chamber receiving unfiltered liquid in the filtering mode, an outlet chamber receiving filtered liquid from the inlet chamber in the filtering mode, and a filter screen unit separating the inlet chamber from the outlet chamber and being configured to filter particles from liquid flowing from the inlet chamber into the outlet chamber, wherein the filter screen unit is rotatable about an axis of rotation, characterized in that at least a part of the inlet chamber is located radially outward of the rotatable filter screen unit with respect to the axis of rotation, and the filtering device is configured to be operated in a self-cleaning mode in which the filter screen unit is rotated to detach filtered particle-sludge from the filter screen unit.
