    摘要： An apparatus and a method for controlling a degree of attrition or wear of a sealing screw conveying plasticized material are provided. The apparatus includes an opening which intersects the wall of a housing of the screw in the region of the screw threads or in the region immediately neighboring the screw threads. Another opening intersects the wall of the housing. The two openings are spaced apart axially from each other and the pressure sensors connected to both openings. The process involved conveys a plasticized material against a resistance, the resistance being a sealing screw bearing supported within the screw housing. The pressure of the conveyed material is measured at two locations spaced apart from each other in the direction of conveyance. The two locations are disposed on both sides of a resistance body towards which the sealing screw conveys the material. The difference between the two measured values is used to indicate the degree of wear of the screw or its housing, respectively.

    摘要： An apparatus for pre-treatment of thermoplastic synthetic plastics material, for example polyester waste, comprises at least two receptacles (1,13) disposed in series following each other, in each one of which receptacles a comminuting or mixing tool (5) rotates around a vertical axis (4) in the bottom region of the receptacle (1 or 13). At least the downstream receptacle has an evacuation line (18) through which, optionally also a protective gas can be introduced. The receptacles (1,13) are connected to each other by a tube piece (12) in which a shut-off means (20) is disposed so that the vacuum in the downstream receptacle (13) can be maintained without any problem until the shut-off valve (20) is opened, whereupon the vacuum in the receptacle (13) sucks on the material positioned in the upstream receptacle (1). Therefore, in the upstream receptacle (1)--when seen in flowing direction of the synthetic plastics material--the synthetic plastics material is pre-comminuted, pre-heated, pre-dried and pre-compressed, what is still assisted by the turbulence when sucked-in into the downstream receptacle (13). In such a manner, completely homogeneous material is conveyed by a worm (16) connected to the last receptacle (13) to further processing (FIG. 1).

    摘要： A backflushable filtering apparatus for a molten material, particularly for a plastic melt, comprises a housing (1) in which a sieving arrangement (17) is provided which includes at least two sieving sections (16) separated from one another. The melt to be filtered is supplied to the sieving sections (16) through at least one distributor (3). The distributor (3) includes at least one control body (9) for backflushing which is moveable within a housing (53) that is provided with an inlet opening (4) for the material to be filtered. The control body (9), in a filtering position, unblocks the influx of material to be filtered to all sieving sections (16) through connection channels (23). However, in a backflushing position, the control body (9) interrupts the influx of material to the filtering section (16) to be backflushed and interconnects the connection channel (23) of the sieving section (16) flushed back with a discharge channel (28) located in the control body (9). At least the majority of the circumference of the control body (9) is surrounded by a distribution space (7) for the material to be filtered which is situated within its housing (53). The distribution space (7) is connectable through the connection channels (23) to all sieving sections (16) in communication with the distributor (3). Guiding channels (6) lead from the inlet opening (4) to the regions of the two front ends (61, 62) of the distribution space (7). These front ends (61, 62) are situated in the region of the outermost connection channels (23) or outside the region of all connection channels (23). The discharge channel (28), which leads away from the control body (9), may be caused to communicate with the connection channel (23) of the respective sieving section (16) to be flushed back through a flush back channel (27) of at least one cross-piece (14) of the control body (9) which overbridges the distribution space (7).

    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).

    摘要： An apparatus for filtering thermoplastic synthetic plastic material has a screw (5) bearingly supported within a housing (1) for rotation around its longitudinal axis for the transport and preferably also plasticizing of the synthethic plastic material. This material is supplied to the screw (5) through an intake opening (7) into the housing (1) and leaves the housing (1) through an exit opening (8). The screw (5) is subdivided into two sections (9, 10) disposed one behind the other in axial direction. A filter (40) provided with penetration openings (25) is disposed in the flow of the synthetic plastic material that is disposed between these two sections (9, 10), which filter (40) is disposed within the housing (1) between the two sections (9, 10) of the screw (5) so that it subdivides the interior of the housing. The filter (40) is connected for common rotation with at least one of the screw sections (9, 10). At least one scraper (26) mounted in the housing (1) engages the upstream side of the filter (40) and strips off coarse impurities from the filter when the filter (40) is rotated and conveys the impurities into a collecting space (27) that is in connection with the interior of the housing.

    摘要： A filter apparatus for thermoplastic synthetic plastics material includes a screen carrier member having at least one screen nest, the screen carrier member being shiftable in a longitudinal direction in a housing. For backwashing the screen nest, the screen nest is in connection with a washing channel in a washing position of the screen carrier member In order to make the washing process quickly, effectively and uniformly over the surface of the screen and in order to avoid an additional loss of the mass in the main flow at the backwashing process, a storage space is provided in the screen carrier member which is filled in normal operation with cleaned melt. A piston in the storage space is shifted for moving the material provided in the storage space in the backwashing direction through the screen nest and into the washing channel.
