摘要： This invention concerns a process for monitoring the degree of wear of a compression worm (8) which conveys a plasticized material, in particular, plastic, against an element that exerts a resistance and is located in a worm housing (4). To this effect, the pressure of the material conveyed is measured at two points disposed at intervals along the direction of travel. These two points are situated at both sides of a resistance body (12) towards which the compression worm (8) conveys. The difference between the two pressures measured is used to display the degree of wear of the worm (5) and its housing. A device for that purpose has an opening (18) which penetrates the wall (20) of the housing (4) of the worm (5) in the region of its thread or in a region immediately adjacent thereto. An additional opening (19) penetrates the wall of this housing (4); both openings (18, 19) are disposed axially at a distance from each other. A pressure sensor (22, 23) is linked to each opening (18, 19).

摘要： Described is a filter for plastic melts containing impurities, the filter having a housing (1) in which a cylindrical or conical filter element (3) is mounted so that it can be rotated by a drive shaft (6) about its longitudinal axis (4). Lying against the outside surface (15) of the filter element is a scraper (20) which surrounds the filter element (3) in the form of a spiral. The material to be filtered is fed into the filter element from the outside through an inlet port (12). The filtrate passes through apertures (16) in the filter element (3) into the central cavity inside the filter element (3), from where it is removed through an outlet port (18). The impurities cannot pass through the apertures (16) in the filter element (3), but collect on the outside surface (15) of the filter element (3) and are conveyed by the fixed scraper (20) to a discharge port (24). This gives a simple design which is reliable in operation.

摘要： Disclosed is a device for degassing thermoplastics, the device having a first worm-conveyor zone (11) for feeding in the material to be treated. The plastified plastic material flows out of the housing (10) of this worm-conveyor zone (11) through a connecting channel (15) to a filter (16) and from there through an inlet aperture (17) into the housing (18) of a second worm-conveyor zone (19) which conveys the material to an outlet (21). Lying between the two equiaxial worm-conveyor zones (11, 19) is a seal zone (26) which prevents the filter (16) from being bypassed. Immediately downstream of the inlet aperture (17) is a baffle barrier (28) which forces the stream of plastic into a tubular shape. The baffle barrier (28) can be adjusted relative to the inlet aperture (17) in the longitudinal direction and has a cross-section which tapers towards the second worm-conveyor zone (19). This shortens the migration path for gas bubbles from the plastic material and thus facilitates the degassing through the degassing aperture (20).

摘要： The invention relates to a device for continuously recycling synthetic material, preferably polyester, having a first receptacle (2) for the material in which moving tools (9) are arranged that comminute and/or mix said material. The pretreated material is transported from this receptacle (2), via a channel (18) that can be vacuum sealed, and into a second receptacle (19) whose interior can be evacuated. Tools (22) which also move and which process the material are provided in this second receptacle. The material is removed from the second receptacle (19) by means of a worm (30). Another worm (15) is mounted in the channel (18) and has spirals which convey the material out of the first receptacle (2) and into the second receptacle (19). At least one blocking element (39) which is situated in the flow of the conveyed material is provided in the channel (18) between the spirals (52) of the other worm (15) and the second receptacle (19). This enables the second receptacle (19) to be completely vacuum sealed during continuous operation of the device.

摘要： The invention relates to a device for processing thermoplastic synthetic material, especially for the purpose of recycling, comprising a cutting compartment (2) in the bottom area (4) of which a grinding mill (5) is disposed that is provided with at least one rotor (6) rotating about a horizontal axis (9). Said rotor (6) carries on its periphery tools that reduce the material to be processed in size, especially knives (20) that are associated with stationary counter-bearings, especially counter-knives (21). At least one compression tool (15) is provided in the cutting compartment (2), which forces the synthetic material against the grinding mill (5), particularly a tamping slide (16) that is disposed in the bottom area (4) of the cutting compartment (2). The material reduced in size in the cutting compartment (2) is transported away by a screw (13), especially an extruder screw. The cutting compartment (2) communicates with a mixing compartment (23) into which the synthetic material is conveyed from the grinding mill (5). At least one rotating mixing organ (24) is disposed in the mixing compartment, which swirls the synthetic material and optionally reduces it in size and conveys the so treated material to the screw (13) and/or to the terminal section (33) of the grinding mill (5) neighboring the screw (13).

摘要： A device for filtering plasticised thermoplastics has a housing (1) with at least one supply channel (6) for the material to be filtered, via which said material is taken to the inlet side of at least one filter unit (3). The filtrate passes through fine holes (7) in the filter unit (3) and passes from its discharge side into at least one outlet channel (9) leading out of the housing (1). The inlet side of the filter element is scraped by the edges of doctor blades (11) moved in relation to said filter element (3), which guides the residues along the surface of the filter element (3) to at least one discharge channel (12). In the residue discharge direction the region (20) provided with holes (7) of the filter element adjoins an unperforated region (21) which is also scraped by the doctor blades (11). In the surface of the unperforated region (21) facing the doctor blades (11) there are grooves (29), the direction of which crosses that of the edges (24) of the doctor blades (11) extending over said grooves (29). The thickened compound on the unperforated region (21) is thus taken in concentrated form to the discharge channel (12).

The outlet openings (11) are situated on the front end of the housing (8) and behind a delivery head (18) comprising a worm section which turns with the agglomerating worm (12). The number of spires per length unit of said worm section is greater than that of the agglomerating worm (12). Grooves (33) are arranged in the housing (8) in the vicinity of said delivery head (18). The direction of said grooves cross with each of the worm spires of the delivery head (18) such that the delivery head (18) additionally compacts and agglomerates the material which has already been largely agglomerated by the agglomerating worm (12). This results in improving the quality of the agglomerate obtained.

摘要： A device for plasticising thermoplastic materials has a revolving feed screw (13) for plasticising the plastic materials within a housing (12). The plastic materials to be plasticised are supplied to the feed screw (13) by a feeding device (27) through a feeding hole (10) in the housing (12). The housing (12) of the feed screw (13) is provided on its inner wall with at least two broad pockets (23, 24). These pockets (23, 24) extend in the longitudinal direction of the feed screw (13) and are mutually separated by narrow ribs (25, 26), when compared to the width of the pocket. One pocket (24) is open towards the feeding hole (10), the other pockets (23) are sealed against the feeding hole (10) by at least one rib (25, 26) of the housing (12) of the feed screw (13). In order to improve filling of the feed screw (13), a feeding device (27) for the plastic materials to be processed is associated with the feed screw (13). This feeding device (27) stuffs the plastic materials into the feeding hole (10) of the housing (12) of the feed screw (13) with a component of motion normal to the longitudinal axis of the feed screw (13). The depth of the pocket (24) open towards the feeding hole (10) is at least constant, seen in the direction of rotation of the feed screw (13). Alternatively or in association therewith, one of the ribs (25, 26) may be adjustable, to allow the feeding capacity of the feed screw (13) to be modified according to the plastic materials to be processed.
