Abstract
(DE) Eine Schwerlast-Wirbelrinnenvorrichtung (1) zur Behandlung von Kunststoffgranulat umfasst eine Vibrationsrinne (10) zur Aufnahme von Kunststoffgranulat, welche einen Rinnenboden (11) und zwei einander gegenüberliegende Seitenwände (12a, 12b) aufweist, wobei die Länge der Vibrationsrinne (10) in Längsrichtung (a) größer ist, als die maximale Höhe und Breite eines zur Längsrichtung senkrechten Rinnenquerschnitts; mindestens zwei Schwingungserreger (20) zur Erzeugung einer Schwingungserregung, welche eine Querkomponente (y) senkrecht zu einer durch die Längsrichtung (a) und Vertikalrichtung (z) gebildeten Ebene aufweist; und mindestens zwei Rinnenträger (31), die in Längsrichtung (a) der Vibrationsrinne (10) voneinander beabstandet sind, jeweils den Rinnenboden (11) und die Seitenwände (12a, 12b) von außen abstützen und ferner die Vibrationsrinne (10) an der dem Rinnenboden (11) gegenüberliegenden Seite überbrücken, wobei an mindestens zwei der Rinnenträger (31) jeweils einer der Schwingungserreger (20) befestigt ist. Weiterhin wird ein Verfahren zur Kristallisation von zum Verkleben neigendem Kunststoffgranulat angegeben.
(EN) The invention relates to a heavy load vortex internal apparatus (1) for handling plastic granular material, comprising a vibration channel (10) for receiving plastic granular material, which vibration channel has a channel floor (11) and two side walls (12a, 12b) which are opposite each other, wherein the length of the vibration channel (10) is greater in the longitudinal direction (a) than the maximum height and width of a channel cross section perpendicular to the longitudinal direction; at least two vibration generators (20) for generating a vibration excitation which has a transverse component (y) perpendicular to a plane formed by the longitudinal direction (a) and the vertical direction (z); and at least two channel carriers (31) which are spaced apart from each other in the longitudinal direction (a) of the vibration channel (10), each supporting the channel floor (11) and the side walls (12a, 12b) from the outside and furthermore bridging the vibration channel (10) on the side opposite the channel floor (11), wherein one of the vibration generators (20) in each case is fastened to at least two of the channel carriers (31). The invention furthermore relates to a method for crystallization of plastic granular material which tends to stick together.
(FR) L'invention concerne un appareil interne (1) à vortex de charge lourde pour la manipulation d'un matériau granulaire en plastique, comprenant un canal de vibration (10) pour recevoir un matériau granulaire en plastique, lequel canal de vibration présente un fond de canal (11) et deux parois latérales (12a, 12b) qui sont opposées l'une à l'autre, la longueur du canal de vibration (10) étant plus grande dans la direction longitudinale (a) que la hauteur et que la largeur maximales d'une section transversale de canal perpendiculaire à la direction longitudinale ; au moins deux générateurs de vibrations (20) pour générer une excitation vibratoire qui présente une composante transversale (y) perpendiculaire à un plan formé par la direction longitudinale (a) et la direction verticale (z) ; et au moins deux supports de canal (31) qui sont écartés l'un de l'autre dans la direction longitudinale (a) du canal de vibration (10), chacun supportant le fond de canal (11) et les parois latérales (12a, 12b) depuis l'extérieur et pontant en outre le canal de vibration (10) sur le côté opposé au fond de canal (11), l'un des générateurs de vibrations (20), dans chaque cas, étant fixé à au moins deux des supports de canal (31). L'invention concerne en outre un procédé de cristallisation d'un matériau granulaire en plastique qui tend à coller ensemble.
