Claims
- 1. Apparatus for introducing and mixing a first liquid with a second liquid in which the latter is present as a body of liquid confined within an enclosure, means for flowing the first liquid in a linear stream downwardly towards the body of the second liquid, a disc mounted for rotational movement located in spaced relation above the body of liquid, means for rotating the disc at high speed in the path of the downwardly moving stream of the first liquid whereby the stream of the first liquid is intercepted by the rotating disc and thrown centrifugally outwardly from the disc as droplets, an agitator mounted for rotational movement at high speed about an axis aligned with the axis of rotation of the disc with at least a portion of the agitator immersed in the body of the second liquid whereby a portion of the second liquid is displaced by the agitator from the body of liquid as droplets which spread upwardly and outwardly along an arcuate path above the body of liquid and which intersects with the droplets of first liquid thrown from the disc member whereby a mixture of the two liquids occurs at the intersection above the body of liquid.
- 2. Apparatus as claimed in claim 1 in which the disc is mounted for rotational movement in a substantially horizontal plane.
- 3. Apparatus as claimed in claim 1 in which the agitator is formed with relief portions which are so disposed as to impart to the fraction displaced from the body of liquid, a form close to a paraboloid of revolution, which falls back into the body of liquid.
- 4. Apparatus as claimed in claim 2, characterized in that it comprises a substantially vertical tube disposed adjacent the axis of the agitator at the upper end of which tube the liquid is introduced with the lower end opening onto a disc, so as to produce a substantially horizontal sheet of droplets, and so as to cause the substantially horizontal sheet of droplets of liquid to intersect above the liquid level with the fraction of a second liquid displaced above said level.
- 5. Apparatus as claimed in claim 1 which includes a shaft on which the agitator is fixed for rotational movement, characterized in that for introducing the liquid, it comprises an annular space concentric to the rotary shaft, said space being laterally delimited by a cylindrical sleeve member whose diameter is greater than the diameter of the shaft, and communicating with an inlet for the first liquid, in its upper part by a protective cap, and in its lower part by the disc fixed to extend perpendicularly to the shaft of the agitator, the sleeve member being separated from the disc by an adjustable clearance which permits the liquid to pass, so as to cause the substantially horizontal sheet of droplets of first liquid to intersect above the level of the body of liquid with the fraction of substantially liquid medium that is displaced above said level.
- 6. Apparatus as claimed in claim 5, which includes apertures in the sleeves so as to cause the substantially horizontal sheet of droplets of first liquid to intersect above the liquid level with the displaced fraction of second liquid dispersed above said level.
