Patent

CA 2577834

The invention relates to a device for granulation of an ejected material from at least one nozzle (7), in particular a thermoplastic plastic, with a perforated plate (2) comprising the nozzles (7). A blade head (10), supporting several blades (11) lies opposite the same, fixed to a shaft (9) which is rotatably driven by a motor (13). The motor (13) is suspended such as to be displaced relative to the housing (1) by means of a suspension (15), however the above is suspended in such a manner that displacement is only possible in the direction of the axis (8) of the shaft (9) and not in a radial direction. Said suspension (15) comprises at least one membrane (14) which suspends the motor (13) on the granulator housing (1). The motor (13) can be adjusted relative to the perforated plate (2) by means of an adjuster device (27), such that the desired pressure of the blade on the perforated plate (2) is maintained. The excised granulate particles are drawn out of the housing (1) by means of a coolant.

L'invention concerne un granulateur servant à mettre sous forme de granulés une matière extrudée à partir d'au moins une filière (7), ledit granulateur présentant une plaque perforée (2) présentant les filières (7). Face à cette plaque perforée se trouve un porte-lames (10) qui comporte plusieurs lames (11) et qui est fixé sur un arbre (9) entraîné en rotation par un moteur (13). Ce dernier (13) est suspendu de manière mobile par rapport au boîtier au moyen d'une suspension (15), cependant de manière à ce que cette possibilité de mouvement ne soit possible que dans le sens de l'axe (8) de l'arbre mais pas dans le sens radial. Cette suspension (15) présente au moins une membrane (14) qui suspend le moteur (13) au boîtier (1) du granulateur. Un dispositif de réglage (27) permet de déplacer le moteur (13) par rapport à la plaque perforée (2) de sorte que les lames exercent en permanence la pression souhaitée sur la plaque perforée (2). Les granulés obtenus sont évacués du boîtier (1) au moyen d'un agent de refroidissement.
