Title
(EN) DEVICE FOR MIXING FLUID MEDIUMS
(FR) DISPOSITIF DE MELANGE DE FLUIDES
Abstract
(EN)
The proposed device for mixing fluid mediums comprises: a vertical inlet pipe (1) directly connected to a mixing chamber (2); distribution chambers (3, 4, 5); preliminary and final mixing units (15 and 16 respectively); and a discharge pipe (28). The distribution chambers are configured coaxially around the vertical pipe and each chamber is divided into intercommunicating areas A and B at least one of which also communicates with the mixing chamber (2). The mixing chamber houses the assembly for mixing the components comprising the preliminary and final mixing units (15 and 16 respectively); these units are mounted on a single shaft (14) and take the form, respectively, of a turning rotor and a fixed stator which is mounted on the mixing chamber housing. The components to be mixed, which are evenly spread around the annular spaces in the distribution chambers, are directed via discharge channels (11) into the mixing chamber (2) and onto the preliminary mixing element rotor (18) which turns at a speed n > 3000 revs/min. The ent ire volume of the fluid medium containing the components undergoes intensive mixing, which results in a high degree of homogeneity and high quality in the final mixture.

Le dispositif de l'invention destiné à mélanger des fluides comprend: un orifice vertical (1) relié directement à une chambre de mélange (2), des chambres de distribution (3, 4, 5), des unités de mélange préliminaire et finale (15 et 16) et un orifice de sortie (28). Les chambres de distribution sont configurées coaxialement autour de l'orifice vertical et chaque chambre est divisée en zones d'intercomunication A et B, dont au moins une communique également avec la chambre de mélange (2). La chambre de mélange contient l'ensemble de mélange des constituants comprenant les unités de mélange pléliminaire et final (15 et 16), ces unités sont montées sur un axe unitaire (14) et se présentent, respectivement, sous la forme d'un rotor tournant et d'un stator fixe monté sur le corps de la chambre de mélange. Les constituants à mélanger, lesquels sont répandus uniformément autour des espaces annulaires dans les chambres de distribution, sont dirigés par l'intermédiaire des canaux de décharge (11) jusque dans la chambre de mélange (2) et sur le rotor (18) de l'élément de mélange préliminaire, lequel tourne à une vitesse de n > 3000 tours/min. Le volume total du fluide contenant les constituants subit un mélange intensif se traduisant par un degré élevé d'homogénéité ainsi qu'une haute qualité de mélange final.
