Title (EN) A TRANSMISSION ASSEMBLY FOR A SLURRY MIXER AND A FLOTATION CELL HAVING SUCH A TRANSMISSION ASSEMBLY
(FR) ENSEMBLE DE TRANSMISSION POUR UN MÉLANGEUR DE SUSPENSION ET CELLULE DE FLOTTATION ÉQUIPÉE D'UN TEL ENSEMBLE DE TRANSMISSION
Abstract:
(EN) A transmission assembly (1) for a slurry mixer with fluid addition via a mixer shaft (5), comprising a gear transmission device (2) having an input shaft (3) for receiving input rotation and an output shaft (4). Said assembly also comprises a slurry mixer shaft (5) fixed to the output shaft (4), extending towards a slurry mixer direction, the slurry mixer shaft (5) having an axial inner passage (5a) extending there through for conducting a fluid flow. The output shaft (4)) is a hollow tubular shaft arranged to nest a portion (5c) of the slurry mixer shaft (5), wherein the slurry mixer shaft (5) comprises, on a portion (5b) not nested by the output shaft (4), in the slurry mixer direction, a discontinuity (5b') on the mechanical structure thereof, arranged to exhibit a local maximum on internal stresses. A flotation cell (8) having such an assembly (1) is also concerned
(FR) Un ensemble de transmission (1) pour un mélangeur de suspension avec addition de fluide par l'intermédiaire d'un arbre de mélangeur (5), comprend un dispositif de transmission à engrenage (2) ayant un arbre d'entrée (3) pour recevoir une rotation d'entrée et un arbre de sortie (4). Ledit ensemble comprend également un arbre de mélangeur de suspension (5) fixé à l'arbre de sortie (4), s'étendant vers une direction de mélangeur de suspension, l'arbre de mélangeur de suspension (5) ayant un passage interne axial (5a) s'étendant à travers celui-ci pour conduire un écoulement de fluide. L'arbre de sortie (4)) est un arbre tubulaire creux agencé pour s'emboîter dans une partie (5c) de l'arbre de mélangeur de suspension (5), l'arbre de mélangeur de suspension (5) comprenant, sur une partie (5b) non emboîtée par l'arbre de sortie (4), dans la direction du mélangeur de suspension, une discontinuité (5b') sur sa structure mécanique, agencée pour présenter un maximum local sur les contraintes internes. L'invention concerne également une cellule de flottation (8) équipée d'un tel ensemble (1).
