Abstract

In a rotary conical filter drum with a perforated peripheral wall, a pipe at the large end of the drum for the removal of solids separated by filtration, a feed pipe inside the drum for the liquid to be filtered, and tubes for spraying a liqid on the external peripheral surface, a conical filter surrounds concentrically and is fixed to the drum with which it rotates, and widens in the same direction, but has a less rigid surface with finer perforations, being formed e.g. by a filter cloth on a perforated metal sheet.
