Abstract

Le problème à résoudre dans le cadre de cette invention consiste à proposer un appareil de mélange ayant une structure simple et pouvant générer un flux à phase mixte composée d'un liquide et de granulés, ou bien composée d'un liquide, de granulés et d'un gaz, sans appliquer de pression ou analogue au mélange. La solution proposée consiste en un appareil de mélange destiné à mélanger un liquide avec des granulés. L'appareil de mélange comprend un aspirateur (2) et un équipement fournissant le mélange (3) connecté à l'aspirateur (2) et il est caractérisé en ce que l'aspirateur (2) comprend un orifice d'aspiration (6) destiné à aspirer le mélange, une buse d'éjection (4), qui a un diamètre réduit vers un orifice d'éjection (4b) et éjecte un liquide (16) à travers ledit orifice (4b), une paroi externe (7) destinée à entourer ledit orifice (4b), une partie d'aspiration (8) formée entre la paroi externe de sa surface périphérique interne (7a) et la buse d'éjection (4) de sa face périphérique externe (4c), et une buse de réception (5) destinée à recevoir le liquide éjecté à travers la buse d'éjection (4) et le mélange aspiré à travers l'orifice d'aspiration (6). L'équipement fournissant le mélange (3) est raccordé à l'aspirateur (2) dans son orifice d'aspiration (6) et comprend une partie fournissant le liquide (12) et une partie fournissant les granulés (11).
