Abstract

L'invention concerne une machine à traiter des matières visqueuses ou particulaires équipée d'un dispositif d'étanchéité perfectionné. Ledit dispositif d'étanchéité comprend un joint dynamique 27 qui est destiné à maîtriser une fuite de la matière entre des surfaces complémentaires 14, 26 qui sont très rapprochées et qui se déplacent l'une par rapport à l'autre. La fuite est maîtrisée par la présence de plusieurs canaux hélicoïdaux d'étanchéité 27 ménagés dans l'une des surfaces relativement mobiles 14, 26 pour s'opposer à l'écoulement du liquide de fuite entre ces surfaces. Les canaux d'étanchéité, qui peuvent être hélicoïdaux ou obliques, sont ménagés, soit dans la surface rotative soit dans la surface fixe. Application à l'élimination d'une fuite d'une matière liquide à partir des passages de traitement d'une machine rotative destinée à traiter des matières plastiques ou polymères visqueuses.The invention relates to a machine for treating viscous or particulate materials equipped with an improved sealing device. Said sealing device comprises a dynamic seal 27 which is intended to control leakage of material between complementary surfaces 14, 26 which are very close together and which move with respect to one another. The leak is controlled by the presence of several helical sealing channels 27 formed in one of the relatively movable surfaces 14, 26 to oppose the flow of the leakage liquid between these surfaces. The sealing channels, which can be helical or oblique, are provided either in the rotating surface or in the fixed surface. Application to the elimination of a leak of a liquid material from the treatment passages of a rotary machine intended to treat viscous plastics or polymers.
