The invention relates to a device which is used to continuously filter material mixtures, in particular for separating impurities from plastic melts. The device includes a hollow cylindrically-shaped filter element (2) which is arranged inside a housing (1), an annular chamber (22) which is defined from the outside of the filter element (2) and an inner wall of the housing, and at least one stripper (23) which can be pressed onto the filter body by an adjusting device. The stripper is used to remove the impurities detained on the filter element (2) due to a relative movement of the filter element (2) and the stripper (23). The adjusting device contains a pressure sensor (42, 53) which is used to detect the pressure of the material mixture upstream from the filter body and an actuator (43) which is connected to the pressure sensor, the actuator being used to adjust the pressure of the stripper (23) according to the pressure detected by the pressure sensor.
A device for continuously filtering material mixtures, especially for separating impurities from plastic melts, the device usable in an apparatus having at least one stripper operable to remove impurities detained on a filter element, the device comprising:
A device for continuously filtering material mixtures delivered to a filter element under pressure, comprising:
