Abstract

A device for the filtration of liquid media, such as in particular viscous and highly viscous polymer melts, comprises at least one repeatably removable or exchangeable sieve body, provided in a plate (1) mounted to rotate about a rotation point (A), in order to take the body into or out of the medium flow. The plate (1) is connected to a drive by means of a gear (13', 13", 15', 15"). The drive is preferably a toothed gear set.
