Abstract
(EN)
A tumbler may be used as defluidizer, dryer, coater, classifier, or dynamic filter. The tumbler includes a housing for rotatably supporting a removable screened drum on a plurality of rollers. The drum receives a solid/fluid slurry through an inlet chute. As the slurry travels through the drum, fluid exits the drum through a plurality of apertures in screens attached to the sides of the drum, while the solids continue along the drum's length until they reach one or more openings and exit the drum into an outlet chute. The outlet chute includes ridges that wrap around rings extending from the openings of the drum to prevent solids from escaping the outlet chute. To further dry the solids before they exit the drum, an air tube disposed within the drum is configured to direct air through the screens to an air blower intake positioned outside of the drum.

Cette invention concerne un tambour rotatif pouvant être utilisé à titre de défluidiseur, séchoir, dispositif de revêtement, classificateur, ou filtre dynamique. Le tambour rotatif comprend un carter pour le support rotatif d'un tambour à cribles amovible sur une pluralité de rouleaux. Le tambour reçoit une boue solide/fluide par une goulotte d'admission. Au fur et à mesure que la boue progresse dans le tambour, le fluide est évacué du tambour par une pluralité d'ouvertures de cribles fixés sur les côtés du tambour, tandis que les matières solides continuent à progresser sur toute la longueur du tambour jusqu'à ce qu'elles atteignent une ou plusieurs ouvertures et sortent du tambour par une goulotte de sortie. La goulotte de sortie comprend des arêtes qui enveloppent des anneaux s'étendant à partir des ouvertures du tambour pour empêcher les matières solides de s'échapper de la goulotte de sortie. Pour sécher davantage les matières solides avant leur sortie du tambour, un tube à air situé à l'intérieur du tambour est conçu pour diriger l'air à travers les cribles vers la prise d'air d'une soufflante située à l'extérieur du tambour.
