Abstract

A device for the continuous filtering of flowable masses containing solid particles, in particular contaminated plastics melts, comprises a housing (1) in which a hollow cylindrical filter (2) is fixedly arranged. The interior of the filter (2) is fluidically connected to an inlet opening (5) of the housing (1). The mass to be cleaned flows outwards through the filer (2). A cleaning means (12) is arranged in the interior of the filter (2) and is driven so as to rotate about the axis of the filter (2). The cleaning means (12) rests against the inner surface of the filter (2) and feeds the solid particles retained by the filter to a screw (17) which conveys the solid particles to a solid-matter discharge opening (13). The filtrate is collected in a collecting chamber (9) located on the outside of the filter (2) and fluidically connected to an outlet opening (10) of the housing. A hollow shaft (16) of the cleaning means (12) carries, on its outer circumference, at least one scraper (18) for removing the solid particles from the filter (2) and forms a housing for the screw (17) arranged in the hollow shaft (16), the solid particles being fed to the screw (17) through at least one opening (19), adjacent to the scraper (18), in the wall of the hollow shaft.
