MELT FILTER COMPRISING A DRIVE DEVICE FOR A ROTATABLE DISK SCREEN

摘要

The invention relates to a melt filter (1) comprising: at least one rotatable disk screen (2) which holds a screen insert (3), at least one screen insert (3) being displaceable inside the melt filter (1) by means of a drive device for the rotatable disk screen (2) in such a way that said screen insert (3) lies opposite a melt feed opening (6); and comprising a piston (13) for backflushing and/or pre-flooding. The object of the invention is to develop a melt filter such that the drive device for backflushing and/or pre-flooding is simplified. To achieve this object, the piston (13) is operatively connected to the drive device and can be driven by said drive device in order to carry out the backflushing and/or pre-flooding operation.
