Patent

CA 2232858

Described is .a sorting device intended in particular for the fibre suspensions produced when paper is pulped. Fitted to the body (1) of a rotor are vanes (2) which extend out from the surface of the rotor body (1) towards a screen wall (4). The supports for the vanes (2) are made up of several parts and may, for instance, consist o:f two parts - a vane carrier (10,10') and a strut (5,5'). The strut (5,5') is attached to the rotor body (1) by welding (6) for instance. The vane carrier (10,10') and the strut (5,5') are detachably connected to each other so that they cannot rotate, for instance by a screw joint (8,17). To secure the two parts (5,10; 5',10') against rotation, the joint is preferably of the inter-locking type.

L'invention a pour objet un dispositif de triage destiné en particulier à des suspensions fibreuses pour la fabrication de la pâte à papier. Sur un corps de base formé par une roue centrifuge (1) sont prévues des ailettes (2) s'étendant de la périphérie extérieure du corps (1) en direction d'une paroi constituée par un tamis (4). Le support des ailettes (2) est réalisé en plusieurs parties et comprend, par exemple, deux parties: un support d'ailette (10, 10') et un support de montant (5, 5'). Le support de montant (5, 5') est fixé, par exemple par soudage (6), au corps de base (1). Le support d'ailette (10, 10') et le support de montant (5, 5') sont montés amovibles et bloqués en rotation, par exemple par assemblage par vis (8, 17). Comme système de blocage en rotation, il est prévu notamment un raccordement par liaison de forme des deux éléments à assembler (5, 10; 5', 10').
