    摘要: A backwashable filtering device for thermoplastic plastics material is disclosed. The device can filter thermoplastic plastics material through one or more nests of screens in the filtering position, while submitting some nests of screens to the backwashing process that cleans them. The filtering position and the backwashing position are selectable by displacing one or more carrying bodies with respect to a housing and/or by displacing one or more control bodies with respect to the carrying bodies. The backwashing can be performed over an entire nest of screens or over a portion of a nest of screens. The nests of screens can be straight or curved.

    摘要: Within a process for recycling of PET-material and/or objects of PET, the PET-material to be processed is heated and dried in the course of a pre-treatment step and simultaneously is crystallized at elevated temperature. This pre-treatment step is followed by a main-treatment step under vacuum. In this main-treatment step, the processed material is again dried and crystallized at a temperature that is higher than the temperature of the pre-treatment step. Preferably, also in the main-treatment step no plasticizing of the material takes place; the plasticizing or, respectively, melting of the material takes place only after the main-processing step. An apparatus for performing this process comprises a pre-processing device (3) in which the processed material is dried and simultaneously crystallized at elevated temperature, and, if desired, is also comminuted. A main-processing device (4) is connected to this pre-processing device (3), in which main-processing device the supplied PET-material is dried, crystallized and heated to a temperature that is higher than the temperature within the pre-treatment device.

    摘要: An apparatus for reprocessing thermoplastic synthetic plastic material has a receptacle (1) for accomodating the synthetic plastic material, in which receptacle (1) has a rotating tool (4) is provided which presses the synthetic plastic material out of the receptacle (1) into the inlet opening (11) in the side wall of the screw housing (12) of a screw (13). The screw housing (12) of the screw (13) has a pocket-like enlargement (22) in the area of the inlet opening (11), which enlargement (22) provides an additional space for the synthetic plastic material being pressed in. On that edge of the inlet opening (11) on which the direction of rotation of the screw (13) is directed towards the receptacle (1), this enlargement (22) is confined by an adjustable wall piece (23). The enlargement (22) gives way in an area of the screw housing (12) adjoining it to grooves (28), which are of a depth which decreases to the screw diameter and which are separated from each by the rigid ribs (29) projecting toward the screw (13) from the wall of the enlargement (22). Each of these grooves (28) forms a space for the synthetic plastic material, the longitudinal direction of which space runs essentially in the axial direction of the screw (13).

    摘要: An apparatus for granulating thermally unstable synthetic plastic material includes a tip-driven plasticizing screw positioned in a housing. The screw conveys the synthetic plastic material through exit openings in the housing, wherein granulating knives slidably engaged with the housing exit openings cut-off pellets of synthetic plastic material. The drive mechanism for the plasticizing screw is disposed at the exit opening side of the screw with the orbit of the granulating knives disposed between the exit openings and the drive mechanism. The drive shaft of the plasticizing screw is detachably coupled to the front, or exit, end of the screw. A conveyor blower cools the pellets as they are severed from the exit openings, and further operates to convey the pellets to a storage bin for packaging.

    摘要: An apparatus for degassing thermoplastic synthetic plastics material has a first screw section (11) for the intake of the material to be treated. The plasticized synthetic plastics material flows from the housing (10) of this screw section (11) through a connection channel (15) to a filter (16) and from there through an inflow opening (17) into the housing (18) of a second screw section (19) which conveys the material to an outlet (21). Between the two coaxial screw sections (11, 19), a sealing section (26) is disposed which avoids a by-pass of the filter (16). A baffle member (28) is disposed in front of the inflow opening (17) which forces the synthetic plastics material stream into a hose-formed shape. The baffle member (28) is displaceable with respect to the inflow opening (17) in axial direction and has a cross section which tapers towards the second screw section (19). Thereby the migration path of the gas bubbles from the synthetic plastics material is reduced and thereby degassing via the degassing openings (20) is enhanced. (FIG. 1)

    摘要: An apparatus for filling a screw (7) bearingly supported within a housing (6), in particular of an extruder, for processing of pre-comminuted synthetic plastics material, in particular PET, has a filling opening (5) for the screw housing (6). This filling opening (5) is in flow connection with the lower outflow opening (4) of an upright receptacle 81) for the material to be processed. Within the receptacle (1), tools (30, 31) circulate around a, preferably vertical, axis, which tool act onto the material positioned within the receptacle (1). This material is introduced into the evacuable receptacle (1) through a sluice (60). A quickly circulating tool (30) for creating a mixing cone (71) is disposed between an upper interior portion (68) and a lower interior portion (69) of the receptacle (1). Within the lower interior portion (69) that constitutes a dwell space for the heated plastics material that has reached it for thermal homogenization thereof, also circulating tools (31) are disposed, which, however, are mere mixing tools without substantial introduction of power, so that within this dwell space an agglomeration of the plastics material is avoided.

The material thus treated is fed through an outlet opening (17) which is arranged at the bottom of the container (1) and to which the feed opening (18) of a housing (19) is fluidly connected. In this housing are arranged at least two screws (21, 22) which are jointly charged with material. The diameter (D) of the container (1) and the diameter (d) of each of the screws (21, 22) are in the relationship D=103{square root over (d2K)}, where D is the inner diameter of the circular cylindrical container (1) or the inner diameter of a hypothetical circular cylindrical container converted to the same capacity and having the same effective height, d is the screw diameter, and K is a constant greater than or equal to 50.
