Title (EN) DISK SCREEN WITH COMPRESSIBLE SPACERS AND FLANGED SURROUNDS
(FR) CRIBLE A DISQUES AVEC PIECES D'ECARTEMENT COMPRESSIBLES ET DISQUES DE PROTECTION A BRIDE
Abstract:
(EN) A disk screen or like shaft structure is disclosed in which screen disks (14), surround disks (24), and spacers (28) are connected together in modular relation. The surround disks (24) have metallic flanges (25) which shield the plastic spacers (28) which are located on either side of the surround disks (24) between the screen disks (14). The spacers (28) are formed of resilient plastic to allow the disks to deflect from their radial plane and the flanges (25) of the surround disks (24) are sufficiently smaller then the spacers (28) to avoid contact with the screen disks (14) in their deflected positions. The assembly is placed under a predetermined endwise compression and the module is mounted on a rectangular shaft (27) which is suitably supported for rotation. The assembly is particularly suited for screening of wood chips in the paper making industry where exposed plastic parts is undesirable.
(FR) Crible à disques ou structure en forme d'arbre comportant des disques de criblage (14), des disques de protection (24) et des pièces d'écartement (28) assemblés de manière modulaire. Les disques de protection (24) possèdent des brides métalliques (25) qui protègent les pièces d'écartement en plastique (28) situées de chaque côté des disques de protection (24) entre les disques de criblage (14). Les pièces d'écartement (28) sont en plastique élastique afin de permettre aux disques de dévier de leur plan radial et les brides (25) des disques de protection (24) sont de taille suffisamment inférieure à celle des pièces d'écartement (28) pour éviter le contact avec les disques de criblage (14) dans leurs positions déviées. Le dispositif est soumis à une compression axiale prédéterminée et le module est monté sur un arbre rectangulaire (27) qui est soutenu de manière appropriée en vue de sa rotation. Ce dispositif convient particulièrement au criblage d'éclats de bois dans l'industrie du papier où il n'est pas souhaitable que les pièces de plastique soient sans protection.
