  Installation pour le traitement d'un liquide.



   La présente invention a pour objet une installation pour le traitement   d'un    liquide au moyen d'un fluide gazeux, comprenant un bassin, destiné à contenir le liquide à traiter et au moins une pompe rotative dont l'axe porte un organe de brassage, cette pompe coopérant avec une conduite fixe par laquelle s'effectue l'aspiration du fluide gazeux.



   De telles installations sont destinées à être utilisées notamment pour le traitement des eaux.



   L'installation faisant l'objet de l'invention se distingue des installations connues par le fait que la pompe est disposée en dessous du niveau du liquide à traiter et en ce que l'extrémité de la conduite du fluide gazeux plongeant dans le liquide constitue le carter de la pompe.



   Le dessin annexé se réfère à deux formes d'exécution de   l'installatino    selon l'invention.



     La fig.    1 est une coupe à travers la première   forme    d'exéeution.



   La fig.   2    est une coupe d'une partie de la seconde forme d'exécution.



   L'installation représentée à la   fig. 1    comprend   un    bassin   I,    destiné à contenir le liquide à traiter et une pompe rotative   2    noyée dans le liquide à traiter.



   Cette   pompe    rotative est du type à roue centrifuge 3, portée par un arbre   d'entraîne-    ment 4 disposé verticalement. En effet,   eomme    le   montre    le dessin, la pompe 2 est suspendue dans le bassin 1. Pour cela, un bâti formé de traverses   5    est prévu au haut   clu    bassin et sur ce bâti est fixé un moteur électrique 6. Dans cette forme d'exécution, le carter ou bâti 7 du moteur est relié   direetement    à une conduite 8 entourant l'arbre 4. Cette conduite 8 est destinée à l'amenée d'un fluide gazeux, par exemple de l'air, vers le côté aspiration de la roue de pompe.

   Elle porte à son extrémité inférieure un flasque 9   eonstituant    un demi-corps de pompe, dans lequel tourne la roue centrifuge 3 qui est du type à aspiration simple, c'est-à-dire sur une seule face,   crans    le cas présent, la face supérieure qui constitue la face active de la roue. Comme le montre la fig. 1, cette roue est formée par   nli    disque 10 sur l'une des faces duquel sont disposées des ailettes 11.



   L'arbre 4 présente an-dessous de la roue un prolongement 12 portant à son extrémité   iibre    un organe de brassage, en l'occurrence une hélice 13. Cette hélice 13 a pour but de provoquer un brassage du liquide à la partie inférieure du bassin 1, ce brassage étant utilisé dans certains cas pour entraîner en mouvement des corps solides placés dans le tond du bassin, par exemple des   moreeaus       de fer, lorsque 1 'installatiosi est es utilisée pour    le traitement d'eaux usées   à 1 'hydroxyde    de fer.



   Dans cette première forme d'exécution, le bâti du moteur sert lui-même de support au dispositif agitateur en entier, grâce à une bride 14 dont il est muni, cette bride étant boulonnée sur les traverses 5.  



   En outre, les paliers du moteur 6 constituent les paliers de tout l'ensemble rotatif formé du rotor du moteur, de l'arbre d'entraînement 4, de la roue 3 et de l'organe de brassage 13.



   Il est avantageux, en outre, que le moteur soit à vitesse réglable. Dans le cas particulier, le moteur est à double enroulement, ce qui permet l'entraînement de la pompe à deux régimes différents selon que l'installation est fortement chargée on non.



   Le fonctionnement de cette installation est le suivant:
 Lorsque le liquide à traiter est par exemple de l'eau,   l'on    remplit le bassin 1 de   l'eau    à traiter et   l'on    met en marche le moteur 6. La pompe rotative   2    aspire alors de l'air qui entre dans la conduite 8 par des   ouïes    d'entrée 15 et est centrifugé dans la masse d'eau par la roue 3. La roue centrifuge 3 et l'hélice 13 provoquent un mouvement de toute la masse d'eau et la diffusion d'air dans celle-ci produit donc une oxygénation de   1 'eau.   



   Dans les cas où l'eau ne doit pas. seulement être oxygénée, mais encore traitée à l'hydroxyde de fer,   l'on    ajoute dans le   bas-    sin 1, comme cela a été signalé plus haut, des morceaux de fer qui sont   entravés    en   mouve-    ment par l'organe de brassage 13.



   Pour que le rendement de l'installation soit plus favorable, celle-ci travaille en fonctionnement continu, c'est-à-dire qu'un certain débit de liquide brut entre continuellement dans le bassin let que réciproquement une   quantité    correspondante de liquide traité en sort.



     I1    est bien entendu que dans les cas de traitement de petites quantités de liquide, l'installation pourrait aussi fonctionner par phases, c'est-à-dire que   l'on    remplirait le bassin 1 d'eau brute, par exemple, qu'on la soumettrait à une oxygénation, éventuellement aussi à   une    ferrisation et qu'ensuite l'on viderait l'eau traitée du bassin 1 pour la remplacer par une nouvelle charge d'eau brute.



   Dans la seconde forme   d'exéeution    représentée partiellement à la fig.   2,    l'installation est en tout point pareille à la première, sauf en ce qui concerne la roue centrifuge 3. En effet, la roue centrifuge représentée est du type à aspiration sur ses deux faces. Elle est constituée par des palettes 16 fixées radialement sur un moyeu 17 rendu solidaire de   1 'arbre    d'entraînement 4.



   En outre, dans cette dernière forme d'exécution, un palier 18 a été prévu pour l'arbre   dans    la conduite 8. Toutefois, il va de soi que ce palier 18 pourrait être supprimé à eondition que les paliers   (lii    moteur 6 soient prévus en conséquence.



   Il est à noter que les palettes 16 de la roue de pompe représentée à la fig. 2 pourraient être soit plates, soit incurvées, soit   encorde    formées par des fers cornières, par exemple.



   D'autre part, en variante,   l'on    pourrait prévoir un dispositif de réglage permettant de faire varier le débit d'air passant par les   ouïes    15. Il suffirait pour cela de disposer une douille coulissante sur la conduite 8, cette douille   pouvait    être déplacée pour obturer plus ou moins les   ouïes    15.



   Il est bien entendu que   I'installation    au lien de ne comprendre qu'un seul dispositif agitateur pourrait en comprendre   phlsieurs    disposés soit dans le même bassin, soit dans   pînsieurs    bassins.
 



   L'installation représentée au dessein est plus   partieulièrement    destinée au traitement des eaux. Toutefois, il va de soi   qu'une    telle installation pourrait être utilisée pour traiter des liquides antres que de l'eau. De plus, lorsqu'un fluide gazeux autre que de l'air doit être dispersé dans le liquide, il suffit de relier la conduite 8 à une source dudit fluide gazeux et de fermer les ouïes 15.    iEVENDICWTION:

  Installation for the treatment of a liquid.



   The present invention relates to an installation for the treatment of a liquid by means of a gaseous fluid, comprising a basin, intended to contain the liquid to be treated and at least one rotary pump, the axis of which carries a stirring member, this pump cooperating with a fixed pipe through which the suction of the gaseous fluid takes place.



   Such installations are intended to be used in particular for the treatment of water.



   The installation forming the subject of the invention differs from known installations in that the pump is placed below the level of the liquid to be treated and in that the end of the pipe for the gaseous fluid immersed in the liquid constitutes the pump housing.



   The appended drawing refers to two embodiments of the installatino according to the invention.



     Fig. 1 is a section through the first embodiment.



   Fig. 2 is a section through part of the second embodiment.



   The installation shown in fig. 1 comprises a basin I, intended to contain the liquid to be treated and a rotary pump 2 submerged in the liquid to be treated.



   This rotary pump is of the type with a centrifugal impeller 3, carried by a drive shaft 4 arranged vertically. Indeed, as shown in the drawing, the pump 2 is suspended in the basin 1. For this, a frame formed of crossbars 5 is provided at the top of the basin and on this frame is fixed an electric motor 6. In this form of execution, the housing or frame 7 of the motor is directly connected to a pipe 8 surrounding the shaft 4. This pipe 8 is intended for the supply of a gaseous fluid, for example air, to the suction side of the pump wheel.

   It carries at its lower end a flange 9 constituting a pump half-body, in which the centrifugal impeller 3 which is of the single-suction type, that is to say on one side, notwithstanding the present case, turns. upper face which constitutes the active face of the wheel. As shown in fig. 1, this wheel is formed by nli disc 10 on one of the faces of which fins 11 are arranged.



   The shaft 4 has below the wheel an extension 12 carrying at its free end a stirring member, in this case a propeller 13. The purpose of this propeller 13 is to stir the liquid at the lower part of the basin. 1, this stirring being used in certain cases to entrain in motion solid bodies placed in the shear of the basin, for example iron water, when the installation is used for the treatment of waste water with iron hydroxide .



   In this first embodiment, the frame of the motor itself serves as a support for the entire agitator device, thanks to a flange 14 with which it is fitted, this flange being bolted to the cross members 5.



   In addition, the bearings of the motor 6 constitute the bearings of the whole rotary assembly formed by the rotor of the motor, the drive shaft 4, the wheel 3 and the stirring member 13.



   It is also advantageous that the motor is at adjustable speed. In the particular case, the motor is double wound, which allows the pump to be driven at two different speeds depending on whether the installation is heavily loaded or not.



   The operation of this installation is as follows:
 When the liquid to be treated is for example water, the basin 1 is filled with the water to be treated and the motor 6 is started. The rotary pump 2 then sucks in the air which enters the chamber. the pipe 8 by inlet openings 15 and is centrifuged in the body of water by the wheel 3. The centrifugal wheel 3 and the propeller 13 cause movement of the entire body of water and the diffusion of air in the latter therefore produces oxygenation of the water.



   In cases where the water should not. only to be oxygenated, but still treated with iron hydroxide, one adds in the tank 1, as was pointed out above, pieces of iron which are hampered in movement by the stirring member 13.



   So that the efficiency of the installation is more favorable, it works in continuous operation, that is to say that a certain flow of raw liquid continuously enters the basin let that conversely a corresponding quantity of liquid treated in comes out.



     It is understood that in the case of treatment of small quantities of liquid, the installation could also operate in phases, that is to say that the basin 1 would be filled with raw water, for example, that it would be subjected to oxygenation, possibly also to ironing, and then the treated water would be emptied from basin 1 to replace it with a new load of raw water.



   In the second form of execution shown partially in FIG. 2, the installation is in all respects the same as the first, except as regards the centrifugal wheel 3. In fact, the centrifugal wheel shown is of the type with suction on its two faces. It consists of pallets 16 fixed radially on a hub 17 made integral with one drive shaft 4.



   In addition, in this latter embodiment, a bearing 18 has been provided for the shaft in the pipe 8. However, it goes without saying that this bearing 18 could be omitted provided that the bearings (lii motor 6 are provided Consequently.



   It should be noted that the vanes 16 of the pump wheel shown in FIG. 2 could be either flat, or curved, or encorde formed by angle irons, for example.



   On the other hand, as a variant, one could provide an adjustment device making it possible to vary the air flow passing through the openings 15. It would suffice for this to have a sliding sleeve on the pipe 8, this sleeve could be moved to more or less block the gills 15.



   It is understood that the installation at the link to include only one agitator device could include phlsieurs arranged either in the same basin or in pînsieurs basins.
 



   The installation shown on purpose is more particularly intended for water treatment. However, it goes without saying that such an installation could be used to treat liquids other than water. In addition, when a gaseous fluid other than air has to be dispersed in the liquid, it suffices to connect line 8 to a source of said gaseous fluid and to close the openings 15. iEVENDICWTION:

In fact, the centrifugal wheel shown is of the type with suction on its two faces. It consists of pallets 16 fixed radially on a hub 17 made integral with one drive shaft 4. En outre, dans cette dernière forme d'exécution, un palier 18 a été prévu pour l'arbre dans la conduite 8. Toutefois, il va de soi que ce palier 18 pourrait être supprimé à eondition que les paliers (lii moteur 6 soient prévus en conséquence. In addition, in this latter embodiment, a bearing 18 has been provided for the shaft in the pipe 8. However, it goes without saying that this bearing 18 could be omitted provided that the bearings (lii motor 6 are provided Consequently. Il est à noter que les palettes 16 de la roue de pompe représentée à la fig. 2 pourraient être soit plates, soit incurvées, soit encorde formées par des fers cornières, par exemple. It should be noted that the vanes 16 of the pump wheel shown in FIG. 2 could be either flat, or curved, or encorde formed by angle irons, for example. D'autre part, en variante, l'on pourrait prévoir un dispositif de réglage permettant de faire varier le débit d'air passant par les ouïes 15. Il suffirait pour cela de disposer une douille coulissante sur la conduite 8, cette douille pouvait être déplacée pour obturer plus ou moins les ouïes 15. On the other hand, as a variant, one could provide an adjustment device making it possible to vary the air flow passing through the openings 15. It would suffice for this to have a sliding sleeve on the pipe 8, this sleeve could be moved to more or less block the gills 15. Il est bien entendu que I'installation au lien de ne comprendre qu'un seul dispositif agitateur pourrait en comprendre phlsieurs disposés soit dans le même bassin, soit dans pînsieurs bassins. It is understood that the installation at the link to include only one agitator device could include phlsieurs arranged either in the same basin or in pînsieurs basins. L'installation représentée au dessein est plus partieulièrement destinée au traitement des eaux. Toutefois, il va de soi qu'une telle installation pourrait être utilisée pour traiter des liquides antres que de l'eau. De plus, lorsqu'un fluide gazeux autre que de l'air doit être dispersé dans le liquide, il suffit de relier la conduite 8 à une source dudit fluide gazeux et de fermer les ouïes 15. iEVENDICWTION: The installation shown on purpose is more particularly intended for water treatment. However, it goes without saying that such an installation could be used to treat liquids other than water. In addition, when a gaseous fluid other than air has to be dispersed in the liquid, it suffices to connect line 8 to a source of said gaseous fluid and to close the openings 15. iEVENDICWTION: Installation pour le traitement d'un liquide au moyen d'un fluide gazeux, compre- nuant un bassin, destiné à contenir le liquide à traiter et au moires ùne pompe rotative dont l'axe porte un organe de brassage, cette pompe coopérant avec une conduite fixe par laquelle s'effectue l'aspiration du fluide ga zeux, caractérisée en ce que la pompe est disposée en dessous du niveau du liquide à traiter et en ce que l'extrémité de la conduite du fluide gazeux plongeant dans le liquide cons- titue le earter de la pompe.
