Comme on peut le voir aux figures 1 et 2 avec un premier mode de réalisation de l'invention, le dispositif est constitué d'un récipient (10) de forme cylindrique dont le fond est horizontal.
Une conduite (8) achemine du gaz, par exemple de l'air, vers un distributeur (9) placé au centre du fond du récipient (10). Un injecteur tournant (7) est placé au-dessus du distributeur (9). Quatre tiges creuses (12), rendues solidaires de l'injecteur (7) et disposées horizontalement, s'étendent radialement à partir de ce dernier, chaque tige (12) étant perpendiculaire à la tige (12) adjacente.
A l'extrémité opposée de l'injecteur (7), chaque tige (12) est munie d'une buse (6).As can be seen in Figures 1 and 2 with a first embodiment of the invention, the device consists of a container (10) of cylindrical shape whose bottom is horizontal.
A pipe (8) conveys gas, for example air, to a distributor (9) placed in the center of the bottom of the container (10). A rotary injector (7) is placed above the distributor (9). Four hollow rods (12), made integral with the injector (7) and arranged horizontally, extend radially from the latter, each rod (12) being perpendicular to the adjacent rod (12).
At the opposite end of the injector (7), each rod (12) is provided with a nozzle (6).

Les figures 3 et 4 représentent un dispositif identique à celui des figures 1 et 2, à l'exception du fait que, outre un premier système injecteur (7) - tiges (11) - buses (6), il est muni d'un deuxième système injecteur (7) - tiges (12) - buses (6). Le deuxième système est placé au dessus du premier et la longueur de ses tiges (12) est supérieure à celle des tiges (11) du premier système. Figures 3 and 4 show a device identical to that of Figures 1 and 2, except that, in addition to a first injector system (7) - rods (11) - nozzles (6), it is fitted with a second injector system (7) - rods (12) - nozzles (6). The second system is placed above the first one and the length of its rods (12) is greater than that of the rods (11) of the first system.

Les figures 5 et 6 illustrent une buse (6) utilisée dans l'un ou l'autre des dispositifs précédemment décrits, elle comprend deux plaques (3,4) de forme circulaire, superposées l'une par rapport à l'autre et maintenues à distance par l'intermédiaire de trois entretoises (2).
L'extrémité (1) d'une tige (11,12) vient se fixer vers la partie centrale de la plaque circulaire inférieure (3) pour aboutir dans l'espace entre les deux plaques (3,4).Figures 5 and 6 illustrate a nozzle (6) used in one or other of the devices described above, it comprises two plates (3,4) of circular shape, superimposed relative to each other and held remotely via three spacers (2).
The end (1) of a rod (11,12) is fixed towards the central part of the lower circular plate (3) to end up in the space between the two plates (3,4).

La figure 7 illustre schématiquement un système d'acheminement de gaz par la conduite (8) vers les buses (6).
Avant d'accéder dans le distributeur (9), le gaz, dont le chemin est symbolisé par des flèches, passe à travers un filtre (17) et une vanne pneumatique (16), le réglage de la vanne pneumatique (16) étant réglée par un ensemble de régulation (13) commandé à distance (15) et alimenté par un conduit électrique (14).FIG. 7 schematically illustrates a system for routing gas through the pipe (8) to the nozzles (6).
Before entering the distributor (9), the gas, the path of which is symbolized by arrows, passes through a filter (17) and a pneumatic valve (16), the adjustment of the pneumatic valve (16) being adjusted by a remote control regulation assembly (13) (15) and supplied by an electrical conduit (14).

Le choix de la composition des matériaux qui constituent le récipient (10), le distributeur (9), les injecteurs (7), les tiges (11,12) et les buses (6) n'est pas limité. Suivant les substances à mélanger, substances solides par exemple, on choisira des matériaux particulièrement résistants.The choice of the composition of the materials which constitute the container (10), the distributor (9), injectors (7), rods (11,12) and nozzles (6) is not limited. Depending on the substances to be mixed, solid substances for example, we will choose particularly resistant materials.

Le fonctionnement du dispositif est décrit ci-après en se basant notamment sur les figures 3 et 4.
Dans une première phase, la vanne pneumatique (16) est réglée de façon à ce que le gaz soit acheminé jusqu'aux buses (6) et génère des bulles entre les deux plaques circulaires (3,4). En s'élevant dans le récipient qui contient la ou les substances fluides ou solides, les bulles initient le mélange.
Après une durée déterminée, la vanne pneumatique (16) est actionnée de manière à interrompre l'acheminement du gaz vers les buses (6), ce qui entraíne une interruption de la formation des bulles.
Par le biais d'un système de clapets et de conduits non illustrés sur les figures, le gaz est alors acheminé dans un système, constitué par exemple de pales placées à l'intérieur des injecteurs
tournants (7), de façon à faire tourner ces derniers d'un angle déterminé, par exemple 30°. The operation of the device is described below, based in particular on FIGS. 3 and 4.
In a first phase, the pneumatic valve (16) is adjusted so that the gas is conveyed to the nozzles (6) and generates bubbles between the two circular plates (3,4). When rising in the container which contains the fluid or solid substances, the bubbles initiate the mixing.
After a determined period, the pneumatic valve (16) is actuated so as to interrupt the flow of gas to the nozzles (6), which causes an interruption in the formation of bubbles.
By means of a system of valves and conduits not illustrated in the figures, the gas is then conveyed in a system, consisting for example of blades placed inside the injectors
rotating (7), so as to rotate the latter by a determined angle, for example 30 °.

Une fois l'angle de rotation atteint, la vanne pneumatique (16) est actionnée de manière à permettre l'acheminement du gaz au niveau des buses (6), ce qui résulte en un nouveau cycle de mélange tel que décrit précédemment.Once the angle of rotation has been reached, the pneumatic valve (16) is actuated so as to allow gas to be conveyed to the nozzles (6), which results in a new mixing cycle as described above.

II importe de relever le fait que la figure 7 n'est que schématique. La conduite (8) comprise entre la vanne pneumatique (16) et le distributeur (9) peut être constituée d'une pluralité de conduites dont l'ouverture est contrôlée par la vanne pneumatique (16), une partie desdites conduites étant utilisée pour effectuer la rotation des injecteurs (7) alors que l'autre partie assure l'acheminement du gaz vers les buses.It is important to note the fact that Figure 7 is only schematic. Driving (8) between the pneumatic valve (16) and the distributor (9) can be constituted a plurality of pipes, the opening of which is controlled by the pneumatic valve (16), part of said pipes being used to rotate the injectors (7) while the other party ensures the delivery of gas to the nozzles.
