| Zusammenfassung: | An agitator impeller arrangement (1) for dispersing gas into a slurry of solids and liquid, the arrangement comprising an impeller (6) having a plurality of agitating blades (8) mounted radially and equally spaced to the circular hub disc (7). Each agitating blade (8) comprises a lower vertical dispersion blade (9) located below the plane of the circular hub disc (7) parallel to the radius of the circular hub disc, said vertical dispersion blade (9) having a straight vertical outer edge (10) being close to a periphery (11) of the circular hub disc (7), an inner edge (12) which is close to the shaft (2) and a rounded edge (13) curving with a radius r between the outer edge and the inner edge, an upper vertical dispersion blade (14) located above the plane of the circular hub disc (7) and parallel to the radius of the circular hub disc, and an inclined suspension blade (15) located radially outside the periphery of the circular hub disc (7), at a first angle (a) in relation to the vertical direction and below the plane of the circular hub disc.
Se proporciona un mecanismo de hélice agitadora (1) para la dispersión de un gas en una lechada de sólidos y líquido, mecanismo que comprende una hélice (6) con varias paletas agitadoras (8) instaladas en forma radial y a igual distancia del disco de cubo circular (7). Cada paleta agitadora (8) comprende una paleta inferior de dispersión vertical (9) ubicada bajo el plano del disco de cubo circular (7) paralelo al radio del disco de cubo circular, paleta de dispersión vertical (9) que tiene un borde exterior vertical recto (10) cercano al contorno (11) del disco de cubo circular (7), un borde interior (12) cercano al eje (2) y un borde redondo (13) que se curva en un radio (r) entre el borde exterior y el borde interior; una paleta superior de dispersión vertical (14) ubicada sobre el plano del disco de cubo circular (7) y paralelo al radio del disco de cubo circular; y paleta de suspensión inclinada (15) ubicada en forma radial fuera del contorno del disco de cubo circular (7) en un primer ángulo (a) con respecto a la dirección vertical y bajo el plano del disco de cubo circular. |
