Title
(DE) VORRICHTUNG ZUM AUFBEREITEN VON KUNSTSTOFFMATERIAL
(EN) APPARATUS FOR PROCESSING PLASTIC MATERIAL
(FR) DISPOSITIF POUR PRÉPARER UNE MATIÈRE PLASTIQUE
Abstract
(DE) Die Erfindung betrifft eine Vorrichtung zum Vorbehandeln und anschließenden Fördern oder Plastifizieren von Kunststoffen mit einem Behälter (1) mit einem um eine Drehachse (10) drehbaren Misch- und/oder Zerkleinerungswerkzeug (3), wobei in einer Seitenwand (9) eine Öffnung (8) ausgebildet ist, durch die das Kunststoffmaterial ausbringbar ist, wobei ein Mehrschnecken-Förderer (5) vorgesehen ist, mit zumindest zwei in einem Gehäuse (16) rotierenden Schnecken (6). Die Erfindung ist dadurch gekennzeichnet, dass die gedachte Verlängerung der Längsachse (15) des Förderers (5) entgegen der Förderrichtung (17) an der Drehachse (10) vorbeiführt, wobei die Längsachse (15) der dem Behälter (1) nächsten Schnecke (6) ablaufseitig zu der zur Längsachse (15) parallelen Radialen (11) um einen Abstand (18) versetzt ist, und dass die beiden der Einzugsöffnung (80) nächstliegenden Schnecken (6) zueinander gegenläufig sind.
(EN) The invention relates to an apparatus for preprocessing and subsequently conveying or plasticizing plastics, comprising a container (1) with a mixing and/or comminuting tool (3) that can rotate about a rotational axis (10), wherein an opening (8) is formed in a lateral wall (9) through which the plastic material can be discharged and a multiple-screw conveyor (5) is provided with at least two screws (6) rotating in a housing (16). The invention is characterized in that the imaginary extension of the longitudinal axis (15) of the conveyor (5) passes by the rotational axis (10) counter the conveying direction (17), wherein the longitudinal axis (15) of the screw (6) that is closest to the container (1) is on the outlet side offset by a distance (18) in relation to the radial (11) that is parallel to the longitudinal axis (15), and the two screws (6) closest to the feed opening (80) run in opposite directions.
(FR) L'invention concerne un dispositif de pré-traitement et de transport ou malaxage consécutif de plastiques, comportant une cuve (1) présentant un outil de mélange et/ou de broyage (3) tournant autour d'un axe de rotation (10). Une paroi latérale (9) présente une ouverture (8) à travers laquelle le matériau plastique peut être distribué, le dispositif comportant également un transporteur à plusieurs vis (5) présentant au moins deux vis (6) tournant dans un boîtier (16). L'invention est caractérisée en ce que le prolongement imaginaire de l'axe longitudinal (15) du transporteur (5), dans le sens opposé au sens de transport (17), s'étend à côté de l'axe de rotation (10), l'axe longitudinal (15) de la vis (6) la plus proche de la cuve (1) étant décalé côté écoulement, de l'ordre d'un écart (18), par rapport à la radiale (11) parallèle à l'axe longitudinal (15), et les deux vis (6) les plus proches de l'ouverture d'entrée (80) sont contrarotatives.
