VORRICHTUNG UND VERFAHREN ZUR FILTRIERUNG VISKOSEN MATERIALES |
摘要 |
An apparatus for filtering viscous material, in particular thermoplastic synthetic plastic material, comprises a screw ( 24 ), which presses the material to be cleaned from an upstream conduit ( 3 ) of a supply housing ( 2 ) towards a band-shaped screen ( 4 ). The screen ( 4 ) is abutted on its downstream side by a perforated plate ( 6 ) against the pressure of the supplied material. The band-shaped screen ( 4 ) can be displaced for replacement of a soiled band section by a fresh band section. For facilitating this displacement a device is provided, which comprises a closure means ( 30 ) that is disposed on the upstream side of the screen ( 4 ), by which closure means the upstream conduit ( 3 ) for the material to be filtered can be closed at least substantially. On the upstream side of this closure means ( 30 ) a storage space ( 36 ) for material to be cleaned is connected to the upstream conduit ( 3 ). Within this storage space ( 36 ) a piston ( 38 ) is sealingly guided, which is reciprocable by a drive means and closes in its projected position the storage space ( 36 ) against the upstream conduit ( 3 ). |
