Title
(EN) IMPROVED MIXING AND AERATING APPARATUS
(FR) DISPOSITIF MELANGEUR ET AERATEUR AMELIORE
Abstract
(EN) A mixing apparatus comprising a central disc driven by a rotating shaft. A number of mixing plates are stacked above and/or below the central disc. The mixing plates are spaced from and parallel to the central disc. Each plate has a central aperture and the diameter of the central aperture increases progressively away from the central disc to define a space coaxial with the rotating shaft. In operation, fluid is drawn into the space and directed out through the space between the plates. When placed near the surface of a fluid, air is drawn in and the fluid is aerated as well as mixed.
(FR) Ce dispositif mélangeur comporte un disque central entraîné par un arbre rotatif. Un certain nombre de plaques mélangeuses sont empilées au-dessus et/ou au-dessous de ce disque central. Ces plaques, qui sont parallèles au disque central, en sont séparées par un certaine distance. Chaque plaque possède une ouverture centrale dont le diamètre augmente progressivement au fur et à mesure que l'on s'éloigne du disque central et ce, afin de définir un espace coaxial avec l'arbre rotatif. Lorsque le dispositif fonctionne, le fluide est attiré dans cet espace et expulsé dans l'espace existant entre les plaques. Etant attiré, l'air se trouvant à proximité de la surface du fluide pénètre dans celui-ci qui, de ce fait, est à la fois aéré et mélangé.
