A vertical shaft turbine for immersion in a liq. into which the rotating turbine draws and mixes a fluid. The horizontal turbine rotor is open to the liq. in which it is immersed. The fluid to be entrained is ducted vertically down, coaxially, to the hub of the turbine. The duct delivers via a convergent, coaxial cone of which the smaller, outlet end has a dia. only slightly larger than that of the hub. Surrounding liq. is also drawn in towards the hub along the exterior of the cone of which the larger end is encircled by a crown in the form of a coaxial vertical band. The turbine employed for aerating waste water; for promoting flotation of fats etc. to facilitate sepn. Liq. and powdered additives may be simultaneously introduced to treat the water.

Description

La présente invention concerne un dispositif mécanique permettant l'introduction d'un fluide (liquide, gaz, pulvérulent ou deux ou trois réunis) au sein d'un liquide sous forme de fines particules. Dans ce qui suit le mot fluide désigne toujours le corps additionné par l'invention à un liquide. The present invention relates to a mechanical device allowing the introduction of a fluid (liquid, gas, powder or two or three together) within a liquid in the form of fine particles. In what follows the word fluid always designates the body added by the invention to a liquid.

Le dispositif est immergé au sein d'un liquide dans lequel on désire introduire le fluide. Le liquide jout le double role d'agent moteur et de joint d'étanchéité pour le fluide aspiré par une tuyauterie. L'énergie nécessaire est fournie par un arbre tournant mu par un moteur électrique submersible par exemple ou toute autre forme d'énergie similaire. The device is immersed in a liquid into which it is desired to introduce the fluid. The liquid joins the double role of motor agent and seal for the fluid sucked by a pipe. The necessary energy is supplied by a rotating shaft driven by a submersible electric motor for example or any other similar form of energy.

Cette invention est caractérisée par le schéma figue 1 où sont représentés avec comme axe de symétrie X'X
- Une turbine à roue ouverte 1 comportant un flasque plein 11
i Moyeu central 12 et des pales incurvées13 de hauteur h
constante.This invention is characterized by the diagram fig 1 where are represented with as axis of symmetry X'X
- An open wheel turbine 1 comprising a full flange 11
i Central hub 12 and curved blades13 of height h
constant.

- Un tronc de cône d'arrivée de fluide 2 dont le petit dia
mètre est à la partie inférieure près du flasque il de
la turbine et laisse avec le moyeu 12 un anneau faisant
communiquer le liquide avec le tuyau 4.- A trunk of cone of fluid inlet 2 including the small dia
meter is at the bottom near the flange it
the turbine and leaves with the hub 12 a ring making
communicate the liquid with the pipe 4.

- La couronne 3
L'ensemble est plongé dans le liquide. La turbine 1 étant mise en rotation par le moteur de commande, le liquide est en traSné en rotation par la turbine autour du cane 2, aspiré suivant  et refoulé par les pales de la turbine suivant B produisant autour du moyeu central 12 près du flasque 11 une zone de dépures~ sion qui aspire le liquide puis le fluide venant de 4. La turbine refoule alors selon la flèche B un mélange liquide-fluide dont le volume est supérieur au liquide aspiré venant de A d'où la couronne 3 qui vient limiter l'aspiration du liquide et par la mOrne optimiser la dépression aspirant le fluide dans 4 par l'in termédiaire du jeu annulaire entre 2 et 12.Cette couronne peut prendre l'aspect d'un simple disque perpendiculaire et centré sur l'axe Itt et situé à une distance convenable du flasque 11 de la turbine. - Crown 3
The whole is immersed in the liquid. The turbine 1 being rotated by the control motor, the liquid is rotated by the turbine around the pipe 2, sucked along  and discharged by the blades of the turbine according to B producing around the central hub 12 near the flange 11 a zone of depuration ~ sion which sucks the liquid then the fluid coming from 4. The turbine then drives back according to arrow B a liquid-fluid mixture whose volume is greater than the liquid sucked coming from A hence the crown 3 which comes limit the aspiration of the liquid and by the mOne optimize the vacuum sucking the fluid in 4 through the annular clearance between 2 and 12.This crown can take the appearance of a simple perpendicular disc and centered on the axis Itt and located at a suitable distance from the flange 11 of the turbine.

De ces caractéristiques, il en découle que
1/ Le liquide assure ltétanchéité entre parties tournantes
et fixes avec des jeux initiaux importants d'où maintien
des caractéristiques dans le temps malgré l'usure.From these characteristics, it follows that
1 / The liquid ensures the tightness between rotating parts
and fixed with significant initial clearances, hence maintenance
characteristics over time despite wear.

2/ La turbine étant du type à roue ouverte, aubes inclinées
de hauteur constante, le bouchage ou le colmatage des
oueds est minimum, meme si le liquide est chargé de corps
étrangers.2 / The turbine being of the open wheel type, inclined blades
constant height, blockage or clogging of
wadis is minimum, even if the liquid is loaded with body
strangers.

3/ Le volume du fluide (liquide, gaz, ou pulvérulent ou les
trois réunis) admis dans le liquide est ajustable par
modifications des dimensions de l'anneau déterminé par
l'extrémité inférieure de 2 et 12 (diamètre dl et d2)Fig. 2
4/ Le mélange liquide-fluide se fait d'une manière homogène
et continu et le mélange est refoulé dans toutes les
directions perpendiculaires à l'axe de rotation de la tur
bine. Dans le cas d'un gaz, le laminage de celui-ci à la
sortie du càne 2 qui augmente sa vitesse et le hachage
des pales de la turbine produisent de très fines bulles
se répartissant dans le liquide. De plus, au lieu de
création de ces bulles, il y a une dépression qui
s'annulant lorsque le mélange liquide-gaz sort de la tur
bine ce qui réduit le volume des bulles de gaz en sus
pension.Le mélange obtenu liquide-gaz étant de densité
inférieure à celui du liquide, il se produit sponta
nément un mouvement de bas-en haut du mélange liquide-gaz
assurant un brassage de tout l'ensemble.3 / The volume of the fluid (liquid, gas, or powder or
three together) admitted into the liquid is adjustable by
changes in ring dimensions determined by
the lower end of 2 and 12 (diameter dl and d2) Fig. 2
4 / The liquid-fluid mixture is made in a homogeneous manner
and continuous and the mixture is forced back into all
directions perpendicular to the axis of rotation of the tur
well. In the case of a gas, the rolling thereof at the
exit of the caine 2 which increases its speed and the chopping
turbine blades produce very fine bubbles
dividing up in the liquid. In addition, instead of
creation of these bubbles there is a depression which
canceling out when the liquid-gas mixture leaves the tur
bine which reduces the volume of gas bubbles in addition
The liquid-gas mixture obtained having a density
lower than that of the liquid it occurs sponta
a bottom-up movement of the liquid-gas mixture
ensuring mixing of the whole assembly.

5/ Le moteur d'entrainement de la turbine peut entre placé
indifféremment du côté flasque 11 ou du côté arrivée du
fluide 4.5 / The turbine drive motor can between placed
either on the flange side 11 or on the arrival side of the
fluid 4.

Le dispositif objet de l'invention peut être utilisé lorsque lton désire mettre en suspension un fluide dans un liquide que l'on désire traiter : par exemple le traitement des eaux résiduaires. Le liquide est alors des eaux brutes, le fluide de l'air.  The device which is the subject of the invention can be used when it is desired to suspend a fluid in a liquid which it is desired to treat: for example the treatment of waste water. The liquid is then raw water, the fluid is air.

Four le pré-traitement le dispositif assure l'élimination des graisses et parties moussantes en provoquant leur flottation.In the pre-treatment, the device eliminates grease and foaming parts by causing them to float.

Dans le traitement des eaux brutes par oxydation il assure l'oxygénation des eaux à traiter soit à partir de l'oxydation de l'eau, soit par un mélange enrichi en oxygène ou autres gaz nécessaires. In the treatment of raw water by oxidation, it ensures the oxygenation of the water to be treated either from the oxidation of the water, or by a mixture enriched in oxygen or other necessary gases.

Si des additions de produits chimiques doivent être effectuées (liquide ou pulvérulents) une pompe doseuse refoulant dans la tuyauterie 4 peut en assurer la distilation. If chemical additions have to be made (liquid or powder), a metering pump discharging into the piping 4 can ensure its distillation.

Le deuxième aspect de l'invention est l'aspiration d'un fluide, gaz notamment. Le dispositif peut outre utile pour aspirer un gaz toxique au sein d'un liquide qui va en assurer l'assainissement, par garrot des particules en suspension au sein du liquide sous forme de boues ou de composés chimiques. l'aspiration se faisant en continu le dispositif permet également d'effectuer un vide relatif dans une enceinte et de maintenir le vide. The second aspect of the invention is the suction of a fluid, gas in particular. The device can also be useful for sucking a toxic gas into a liquid which will provide sanitation, by tourniquet of the particles in suspension within the liquid in the form of sludge or chemical compounds. as the suction is done continuously, the device also makes it possible to perform a relative vacuum in an enclosure and to maintain the vacuum.

L'invention n'est pas limitée aux exemples choisis, mais elle englobe toutes les variantes.  The invention is not limited to the examples chosen, but it covers all the variants.
