Abstract

The rotor is fixed coaxially to a drive shaft. The agitator can be supported at surface level by a floating assembly or by a fixed structure. The rotor comprises two axially spaced sets of helical blades which provide two-stage agitation as the rotor turns. Rotation can be clockwise or anticlockwise and the speed can be fast or slow. The direction of rotation can be periodically alternated. Used to break up the surface of a liq., partic. water for aeration or degassing. The treatment is partic. applicable to pisciculture installations and to tankers for transporting live fish. The double helix of the rotor induces efficient emulsification of the agitated liq. The result is obtained with a compact, inexpensive rotor.

UTILISATION D'UNE HELICE DOUBLE SUR LES APPAREILS DE
TRAITEMENT DES EAUX.USE OF A DOUBLE PROPELLER ON
WATER TREATMENT.

La présente invention concerne les appareils de traitemen des eaux. en particulier les appareils déposés ou flotta dans ou sur les eaux à traiter.The present invention relates to water treatment devices. in particular the devices deposited or floated in or on the waters to be treated.

Dans les dispositifs connus de ce genre.un moteur(souvent électrique) actionne une hélice multipales. soit par l'in termddiaire d'un réducteur entre le moteur et la dite hélice, ou par attaque directe. L'hélice étant immergée.In known devices of this kind, a motor (often electric) drives a multi-blade propeller. either by means of a reducer between the engine and said propeller, or by direct attack. The propeller being submerged.

L'hélice à double datage selon l'invention présente permet de hacher plus finement la gerbe d'eau produite par l'act de la rotation de l'hélice. et dans le cas de la double hélice, de produire une émulsion plus abbondante. favoris considérablement le dégazage et l'oxygénation de l'eau b traiter. Le nombre de pales de la double hélice est sans importance c'est seul le fait d'avoir deux étage im mergés qui provoque le processus décrit ci-avant.The double-dating propeller according to the present invention makes it possible to more finely chop the spray of water produced by the act of rotating the propeller. and in the case of the double helix, to produce a more abundant emulsion. considerably promotes degassing and oxygenation of the water to be treated. The number of blades of the double helix is irrelevant; it is only the fact of having two immersed stages which causes the process described above.

Le dessin annexé est une vue en élévation d'une hélice double comme expliqué ci-dessus.The accompanying drawing is an elevational view of a double propeller as explained above.

Tel qu'elle est représentée au dessin annexé lthéllce s, compose d'un premier étage(le supérieur) repère 2 du dessin, dans ce cas à trois pales mais qui peut être di.As shown in the accompanying drawing lthéllce s, consists of a first stage (the upper) item 2 of the drawing, in this case with three blades but which can be di.

férent. Le second étage repère 3 (I'inférieur) également dans ce cas à trois pales, mais dont le nombre peut être différent. L'ensemble peut être rigide et entraîné par l'arbre moteur repère I du dessin, cet arbre pouvant êtr soit celui d'un réducteur de vitesse de rotation ou dire tement l'arbre du moteur d'entraînement.proud. The second stage marks 3 (the lower one) also in this case with three blades, but the number of which may be different. The assembly can be rigid and driven by the motor shaft marked I in the drawing, this shaft being either that of a speed reduction gearbox or, in other words, the shaft of the drive motor.

Les deux étages de l'hélice peuvent autre réglables l'un par rapport à l'autre. soit en hauteur ou en orientation angulaire.The two stages of the propeller can further adjustable relative to each other. either in height or in angular orientation.

Le dispositif. objet de l'invention, peut être utilisé dans tous les cas où il est nécessaire de traiter de 1' ( soit dégazage ou aération 5 et tout particulibrement dans les bassins d'élevage de poissons en pisciculture, voir même dans les cuves des camions de transport de po.  The device. object of the invention, can be used in all cases where it is necessary to treat 1 '(either degassing or aeration 5 and especially in fish tanks for fish farming, even in the tanks of trucks po transport.

DESCRIPTION ( Suite
La nature du matériau constituant l'hélice décrite cidessus n'a pas d'influence sur le fonctionnement et peut donc être quelconque#La puissance du moteur d'entraînement de l'hélice n'altère pas la qualité de l'effet décrit ciavant, seul le débit est influencé par cette puissance. DESCRIPTION (Continued
The nature of the material constituting the propeller described above has no influence on the operation and can therefore be arbitrary # The power of the propeller drive motor does not alter the quality of the effect described above, only the flow is influenced by this power.
