Abstract
A device for the continuous filtration of material blends, in particular for separating impurities from plastic melts. A housing has a hollow cylindrical filter disposed inside. An inside chamber is disposed inside the filter. An annular chamber is defined by the outer surface of the filter and an inside wall of the housing. A cleaning device removes the impurities retained on the filter by a motor driving about an axis coupled to pivot the filter inside the housing. The cleaning device has at least one wiper for removing in the radial direction impurities retained on the filter. A conveying device transports off the impurities removed from the filter by the wiper. The motor-driven filter and the conveying device are driven separately of each other.
