Filtering device for plastic melts, comprising a filter replacement device (3), at least one filter housing (4), at least one filter stud (5, 6) which is axially movable inside said housing (4) and has at least one filtering chamber (9, 10) transversely to the longitudinal axis (7, 8) thereof; the filtering chamber (9, 10), which includes at least one filter screen (11, 12), is horizontally oriented in an operating position during a filtering operation and is fluidically connected to at least one fluid delivery duct (14) and at least one fluid discharge duct (15) in the filter housing (4); in order to replace the filter screen (11, 12), the filtering chamber (9, 10) can be moved into a vertical filter screen replacement position (16) outside the filter housing (4). The filter replacement device (3) includes at least one actuator (17) which drives a pushing mechanism (18) and, during a pushing motion of the pushing mechanism (18) into the filter screen replacement position (16), axially moves the filter stud (5, 6) containing the filter screen (11, 12) in the longitudinal direction of the filter stud (5, 6) and pivots the filter stud (5, 6) from the horizontal orientation in the operating position (13) into the vertical filter screen replacement position (16) by means of a gate (20). |
