Abstract

Cette invention concerne un bloc d'étanchéité conçu pour sceller une palette (10) d'une machine de refroidissement circulaire, lequel bloc comprend des dispositifs d'étanchéité permettant d'empêcher toute fuite d'air froid. Ces dispositifs d'étanchéité sont installés séparément sur des positions de la plaque inférieure de fond (12) de la palette (10) entrant en contact avec les parois d'étanchéité (13, 14) intérieure et extérieure et avec les longerons de maintien (31, 32) gauche et droite d'un longeron (30) de forme spéciale de la palette (10). Les dispositifs d'étanchéité installés sur la plaque inférieure de fond (12) entrant en contact avec les parois d'étanchéité (13, 14) intérieure et extérieure et avec les longerons de maintien (31, 32) d'un longeron (30) de forme spéciale constituent le premier dispositif d'étanchéité (20). Ce premier dispositif d'étanchéité (20) présente une traverse (24) et un support (23) qui sont reliés entre eux à angle droit. Un élément d'étanchéité élastique (33) est fixé à l'extérieur du support (23). L'extrémité inférieure de l'élément d'étanchéité (33) vient en contact avec la plaque inférieure de fond (12). La hauteur de l'élément d'étanchéité (33) est légèrement plus importante que la hauteur de l'extrémité inférieure du support (23) en direction de la traverse (24). Cette invention concerne également une machine de refroidissement circulaire. Le bloc d'étanchéité permet d'empêcher l'abrasion et la brûlure du dispositif d'étanchéité par le matériau dispersé; le bloc d'étanchéité permet également de garantir des performances d'étanchéité et d'améliorer l'effet de refroidissement du matériau.
