Abstract
Description
La présente invention se rapporte à une chambre de mélange et/ou de propulsion pour un ou plusieurs composants fluides et dans laquelle au moins un rotor entraîné par un moteur provoque l'agitation de ce ou ces composants. The present invention relates to a mixing and / or propulsion chamber for one or more fluid components and in which at least one rotor driven by a motor causes the agitation of this or these components.
Dans les dispositifs connus à ce jour, l'agitateur, à picots ou à palettes ou de tout autre type, est entraîné par un flexible ou un axe de liaison relié à un moteur électrique ou hydraulique ou a une turbine à air. In the devices known to date, the agitator, with pins or paddles or any other type, is driven by a hose or a connecting pin connected to an electric or hydraulic motor or to an air turbine.
L'étanchéité exigée au droit du flexible ou de l'axe de liaison est rapidement prise en défaut. Les bagues et joints qui l'entourent sont soumis à une usure par frottement, à l'agressivité des produits à mélanger et/ou à propulser, ainsi qu'à celle des solvants de nettoyage utilisés. L'agitateur se déséquilibre, vibre. On note une élévation de température. Les conditions de mélange se modifient au détriment des caractéristiques du produit final. The required tightness in line with the hose or the connecting pin is quickly faulted. The rings and seals which surround it are subject to wear by friction, to the aggressiveness of the products to be mixed and / or to be propelled, as well as to that of the cleaning solvents used. The agitator becomes unbalanced, vibrates. There is an increase in temperature. The mixing conditions change to the detriment of the characteristics of the final product.
En outre, l'emplacement de l'axe de liaison, l'encombre- ment des bagues et joints attenants obligent le plus souvent à l'introduction des composants dans la partie latérale supérieure de la chambre, les entrées étant généralement en opposition. Dans tous les cas, l'image du mélange n'est pas immédiate. In addition, the location of the connecting axis, the size of the rings and adjoining seals most often require the introduction of the components into the upper lateral part of the chamber, the inlets being generally in opposition. In all cases, the image of the mixture is not immediate.
Pour remédier en partie à ces inconvénients et en particulier pour résoudre le problème de l'étanchéité au droit du flexible ou de l'axe de liaison qui relie l'agitateur au moteur, il est connu, notamment dans le domaine des pompes, de séparer la partie tournante d'un moteur électrique de la partie fixe de ce moteur par la paroi d'une canalisation traversant longitudinalement,de façon étanche, l'entrefer tubulaire du moteur électrique. To partially remedy these drawbacks and in particular to solve the problem of the tightness of the hose or of the connecting pin which connects the agitator to the motor, it is known, in particular in the field of pumps, to separate the rotating part of an electric motor from the fixed part of this motor through the wall of a pipe longitudinally passing through, in leaktight manner, the tubular air gap of the electric motor.
Ces dispositifs qui résolvent les problèmes d'étanchéité de l'entraînement de l'axe de liaison, ne résolvent par contre pas certaines difficultés d'entretien. En effet, pour assurer un nettoyage correct, soit après gélification ou solidification partielle ou totale du mélange dans la chambre, soit pour des changements de composants, on est amené à démonter l'agitateur, ce qui entraîne des opérations de montage et de démontage délicates et qui requièrent des temps appréciables. These devices which solve the sealing problems of the drive of the connecting axis, however do not solve certain maintenance difficulties. In fact, to ensure correct cleaning, either after gelling or partial or total solidification of the mixture in the chamber, or for changes of components, it is necessary to dismantle the agitator, which involves delicate assembly and disassembly operations. and which require significant time.
L'un des buts de la présente invention est de réaliser une chambre de mélange et/ou de propulsion qui reste parfaitement étanche même après de longues périodes de service et qui soit d'entretien aisé. A cet effet, la chambre de mélange et/ou de propulsion pour un ou plusieurs composants fluides dans cette chambre dans laquelle au moins un rotor entraîné par un moteur provoque l'agitation et/ou la propulsion de ce ou ces composants et est relié à la partie tournante d'un moteur électrique, d'une part séparée de la partie fixe de ce moteur par la paroi d'une canalisation traversant longitudinalement, de façon étanche l'entrefer tubulaire du moteur électrique, d'autre part immergée, avec ses paliers de support, dans le ou les composants contenus dans la canalisation et entraînée en rotation par l'induction magnétique du moteur électrique (qui traverse l'entrefer et la canalisation) est caractérisée en ce qu'une partie de la chambre de mélange et ou de propulsion est constituée par la partie de l'entrefer du moteur électrique formant un passage annulaire compris entre la partie tournante du moteur électrique et la paroi intérieure de la canalisation traversant longitudinalement 1 'entrefer. One of the aims of the present invention is to provide a mixing and / or propulsion chamber which remains perfectly sealed even after long periods of service and which is easy to maintain. To this end, the mixing and / or propulsion chamber for one or more fluid components in this chamber in which at least one rotor driven by a motor causes the agitation and / or propulsion of this or these components and is connected to the rotating part of an electric motor, on the one hand separated from the fixed part of this motor by the wall of a pipe passing longitudinally, in leaktight manner, the tubular air gap of the electric motor, on the other hand submerged, with its support bearings, in the component or components contained in the pipeline and driven in rotation by the magnetic induction of the electric motor (which crosses the air gap and the pipeline) is characterized in that a part of the mixing chamber and or propulsion system is formed by the part of the electric motor air gap forming an annular passage between the rotating part of the electric motor and the inner wall of the pipe passing longitudinally 1 'between iron.
Avantageusement la partie tournante du moteur électrique utilisé est constituée par l'induit d'un moteur électrique asynchrone, notamment d'un induit à cage (d'écureuil) réalisé en un ensemble résistant à la corrosion, notamment en aluminium coulé, tandis que le circuit magnétique de cet induit est protégé de la corrosion par un revêtement tel qu'un vernis, un émail ou une pellicule de matière plastique enrobant l'ensemble du rotor à l'exception des portées frottantes des paliers. Advantageously, the rotating part of the electric motor used consists of the armature of an asynchronous electric motor, in particular of a cage armature (of squirrel) made of a corrosion-resistant assembly, in particular of cast aluminum, while the the magnetic circuit of this armature is protected from corrosion by a coating such as a varnish, an enamel or a plastic film coating the entire rotor except for the friction surfaces of the bearings.
Selon un autre mode de mise en oeuvre de l'invention, la partie tournante du moteur électrique comporte des aimants de synchronisation de l'induit de ce moteur sur le champ magnétique tournant qui parcourt l'inducteur du moteur électrique et ces aimants de synchronisation de l'induit peuvent faire saillie sur la su-rface extérieure de l'induit pour constituer des ailettes ou nervures de mélange et/ou de propulsion du ou des composants. According to another embodiment of the invention, the rotating part of the electric motor comprises synchronization magnets of the armature of this motor on the rotating magnetic field which traverses the inductor of the electric motor and these synchronization magnets of the armature can protrude from the external su-rface of the armature to form fins or ribs for mixing and / or propelling the component (s).
Le moteur électrique utilisé peut être alimenté à fréquence variable et notamment dans la gamme des fréquences la plus compatible avec la réluctance élevée de son entrefer et son induit peut posséder une résistance électrique importante permettant d'assurer le chauffage du ou des composants fluides par l'intermédiaire de l'énergie électrique dissipée à l'intérieur de cet induit à partir de l'inducteur du moteur. The electric motor used can be supplied at variable frequency and in particular in the range of frequencies most compatible with the high reluctance of its air gap and its armature can have a significant electrical resistance making it possible to ensure the heating of the fluid component (s) by intermediary of the electrical energy dissipated inside this armature from the inductor of the motor.
Avantageusement, l'inducteur du moteur électrique possède un bobinage séparé de chauffage permettant de développer par induction à l'intérieur ou de préférence à la surface du rotor une énergie calorifique de chauffage du ou des- composants. Advantageously, the inductor of the electric motor has a separate heating coil making it possible to develop by induction inside or preferably at the surface of the rotor a heat energy for heating the component (s).
Selon un troisième mode de mise en oeuvre de l'înven- tion, au moins une partie de la surface extérieure de la partie tournante du moteur électrique, pour augmenter le brassa ge et/ou la propulsion du ou des composants, porte des saillies et/ou ailettes et/ou nervures ménagées sur la surface extérieure (de la partie tournante) qui fait face à l'entre- fer du moteur. Ces saillies et/ou ailettes et/ou nervures sont de préférence réalisées en un matériau de bonne perméabilité magnétique par exemple par usinage des tôles magnétiques du rotor de façon à ménager autour des saillies et/ou ailettes et/ou nervures un passage de forme générale annulaire et de section relativement importante pour le ou les composants fluides tout en limitant la réluctance magnétique de l'entre- fer. According to a third embodiment of the invention, at least a part of the external surface of the rotating part of the electric motor, in order to increase the agitation and / or the propulsion of the component or components, carries projections and / or fins and / or ribs formed on the external surface (of the rotating part) which faces the air gap of the motor. These projections and / or fins and / or ribs are preferably made of a material of good magnetic permeability, for example by machining the magnetic sheets of the rotor so as to provide around the projections and / or fins and / or ribs a passage of general shape. annular and of relatively large cross section for the fluid component (s) while limiting the magnetic reluctance of the air gap.
La canalisation traversant longitudinalement l'entrefer, d'une part, peut être réalisée en un matériau résistant à la corrosion (tel qu'un acier inoxydable) et/ou de preférence de bonne qualité frottante tel qu'un polytétrafluoréthylène et, d'autre part, peut être ajustée sur les parties de plus grand diamètre de la partie tournante du moteur électrique de manière à réduire l'entrefer du moteur électrique tout en autori sant d'éventuels contacts entre ces parties de plus grand dia métre et la paroi intérieure à faible coefficient de frottement de la canalisation. The pipe passing longitudinally through the air gap, on the one hand, can be made of a material resistant to corrosion (such as stainless steel) and / or preferably of good rubbing quality such as polytetrafluoroethylene and, on the other hand part, can be adjusted on the larger diameter parts of the rotating part of the electric motor so as to reduce the air gap of the electric motor while allowing possible contacts between these parts of larger diameter and the inner wall to low coefficient of friction of the pipe.
Selon un autre mode encore de mise en oeuvre de l'invention, la paroi intérieure de la canalisation traversant long-itudinalement l'entrefer, pour augmenter le brassage et/ou la propulsion du ou des composants fluides, est munie de saillies et/ou ailettes et/ou nervures, orientées pour exercer un effet de retenue opposé à la rotation provoquée par la partie tournante du moteur électrique. According to yet another embodiment of the invention, the inner wall of the pipe passing long-itudinally through the air gap, to increase the mixing and / or the propulsion of the fluid component (s), is provided with projections and / or fins and / or ribs, oriented to exert a retaining effect opposite to the rotation caused by the rotating part of the electric motor.
Les portées qui soutiennent la partie tournante du moteur électrique dans des paliers peuvent être constituées par un ensemble de deux pointeaux coniques dont chacun est-ménagé à l'une des extrémités différentes de la partie tournante du moteur électrique et vient en appui sur une portée conique conjuguée d'un palier correspondant supporté à l'intérieur de la canalisation. The bearing surfaces which support the rotating part of the electric motor in bearings can be constituted by a set of two conical needles, each of which is formed at one of the different ends of the rotating part of the electric motor and comes to bear on a conical bearing combined with a corresponding bearing supported inside the pipe.
La position axiale d'au moins un des paliers peut être réglable dans les limites permettant le réglage du jeu des paliers de la partie tournante du moteur électrique. The axial position of at least one of the bearings can be adjustable within the limits allowing the adjustment of the clearance of the bearings of the rotating part of the electric motor.
En variante, au moins l'une des arrivées des composants débouche sur la face du palier entourant l'un des pointeaux de la partie tournante du moteur électrique et est munie de moyens de réglage et/ou d'obturation aisément accessibles sur la face du palier débouchant à l'extérieur et constituant un flasque support pour le moteur électrique. As a variant, at least one of the components' inlets opens onto the face of the bearing surrounding one of the needles of the rotating part of the electric motor and is provided with easily accessible adjustment and / or shutter means on the face of the bearing opening to the outside and constituting a support flange for the electric motor.
Selon une autre variante de mise en oeuvre de l'invention, l'axe longitudinal de la partie tournante (rotor) du moteur électrique est monté verticalement, le flasque portant les arrivées des composants réparties autour du pointeau du rotor du moteur électrique étant emmanché de façon étanche sur la canalisation qui traverse longitudinalement l'entrefer du moteur électrique, tandis que l'évacuation du mélange des composants s'effectue à travers le flasque opposé du rotor du moteur électrique dont les paliers inférieur et/ou supérieur sont munis de moyens de réglage axial pour rattraper le jeu axial du rotor. Au moins l'un des paliers supportant la partie tournante du moteur électrique peut être relié à la paroi de la canalisation par au moins un bras participant au brassage des composants. According to another variant embodiment of the invention, the longitudinal axis of the rotating part (rotor) of the electric motor is mounted vertically, the flange carrying the inlets of the components distributed around the needle of the rotor of the electric motor being fitted with sealingly on the pipe which crosses longitudinally the air gap of the electric motor, while the evacuation of the mixture of the components is carried out through the opposite flange of the rotor of the electric motor whose lower and / or upper bearings are provided with means of axial adjustment to compensate for the axial play of the rotor. At least one of the bearings supporting the rotating part of the electric motor can be connected to the wall of the pipeline by at least one arm participating in the mixing of the components.
D'autres buts, avantages et caractéristiques de 1 'inven- tion ressortiront de la description qui va suivre, faite à titre d'exemple non limitatif en regard du dessin annexé sur lequel la figure unique représente une coupe suivant un axe longitudinal d'une chambre de mélange et/ou de propulsion conforme à l'invention. Other objects, advantages and characteristics of the invention will emerge from the description which follows, given by way of nonlimiting example with reference to the appended drawing in which the single figure represents a section along a longitudinal axis of a mixing and / or propulsion chamber according to the invention.
En référence à la figure unique, un stator 1 d'un moteur électrique asynchrone, éventuellement équipé d'un freinage électrique, est relié à une source de courant électrique polyphasée qui peut être alimentée par un variateur continu de fréquence. La carcasse 2 du moteur électrique sert de support à un flasque supérieur 3 et à un flasque inférieur 4. With reference to the single figure, a stator 1 of an asynchronous electric motor, possibly fitted with electric braking, is connected to a polyphase electric current source which can be supplied by a continuous frequency converter. The carcass 2 of the electric motor serves as a support for an upper flange 3 and a lower flange 4.
Une chambre de mélange 5 est délimitée par le bloc/flasque supérieur 3, une canalisation 6 en matière plastique (notamment en téflon) qui travers-e entrefer 18 entre le stator 1 et le rotor 7 du moteur électrique pour l'isoler de façon étanche du stator 1, et par une douille 8 maintenue par le flasque inférieur 4. A mixing chamber 5 is delimited by the upper block / flange 3, a pipe 6 made of plastic (in particular Teflon) which crosses the air gap 18 between the stator 1 and the rotor 7 of the electric motor in order to isolate it in a sealed manner of the stator 1, and by a socket 8 held by the lower flange 4.
Le rotor massif 7 du moteur électrique est muni sur toute sa surface extérieure de rainures usinées directement sur l'empilement des tôles constituant son circuit magnétique. The solid rotor 7 of the electric motor is provided over its entire outer surface with grooves machined directly on the stack of sheets constituting its magnetic circuit.
Ce rotor est muni de deux pointeaux 9 et 10 rapportés ou usinés dans la masse. Ces deux pointeaux reposent chacun sur un palier en métal fritté.This rotor is provided with two needles 9 and 10 added or machined in the mass. These two needles each rest on a sintered metal bearing.
Le palier 11 du pointeau 9 est inséré dans le flasque supérieur 3 et sa position axiale est réglable. Pour permettre de rattraper automatiquement le jeu des pointeaux, il peut également être monté sur ressort. The bearing 11 of the needle 9 is inserted in the upper flange 3 and its axial position is adjustable. To make it possible to automatically make up for the set of needles, it can also be spring-mounted.
Un palier inférieur 12 est enchâssé dans un croisillon profilé 13 logé dans un conduit d'évacuation 14. A lower bearing 12 is encased in a profiled spider 13 housed in a discharge duct 14.
Le flasque supérieur 3 usiné dans un métal tel que l'a cier ou l'aluminium (pour mieux résister à la corrosion) comporte en outre des canaux d'entrée 15 pour les composants fluides à mélanger et/ou à propulser. Des clapets antiretour 16 et des pointeaux de réglage 17 des débits peuvent être disposés dans ces canaux. L'ensemble du moteur électrique et de ses deux flasques d'extrémité peut être entouré d'un manchon permettant de réguler cet ensemble en température. The upper flange 3 machined from a metal such as steel or aluminum (to better resist corrosion) further comprises inlet channels 15 for the fluid components to be mixed and / or propelled. Non-return valves 16 and flow adjustment needles 17 can be arranged in these channels. The assembly of the electric motor and its two end flanges can be surrounded by a sleeve making it possible to regulate this assembly in temperature.
Le dispositif qui vient d'être décrit fonctionne de la façon qui va maintenant être explicitée. Les composants fluides à mélanger et/ou à propulser sont stockés séparément dans des réservoirs attenants ou non au bâti de la machine et qui peuvent être préssurisés et régulés en température. Ces réservoirs alimentent les canaux d'entrée 15 par gravité ou bien des pompes à pistons, à engrenages ou autres propulsent et dosent les composants à mélanger qui sont amenés dans le flasque supérieur 3 par l'intermédiaire de tubes souples ou rigides. Un réglage complémentaire du débit de chaque composant est possible en agissant sur la tête moletée de réglage du pointeau 17. La canalisation 6 qui traverse tout l'entrefer 18 divise celui-ci en deux parties.La partie extérieure 18a présente une forme annulaire lisse et peut se réduire à une valeur très faible, la paroi externe de la canalisation 6 venant toucher la paroi de l'alésage du stator I du moteur électrique. La partie intérieure i8b présente au contraire une section longitudinale dentelée par les saillies et/ou ailettes et/ou nervures 7a ménagées à la surface du rotor 7. The device which has just been described operates in the manner which will now be explained. The fluid components to be mixed and / or propelled are stored separately in tanks adjoining or not to the machine frame and which can be pressurized and temperature controlled. These reservoirs feed the inlet channels 15 by gravity or else piston, gear or other pumps propel and dose the components to be mixed which are brought into the upper flange 3 by means of flexible or rigid tubes. An additional adjustment of the flow rate of each component is possible by acting on the knurled needle adjustment head 17. The pipe 6 which crosses the entire air gap 18 divides the latter into two parts. The outer part 18a has a smooth annular shape and can be reduced to a very low value, the external wall of the pipe 6 coming into contact with the wall of the bore of the stator I of the electric motor. The inner part i8b, on the contrary, has a longitudinal section which is serrated by the projections and / or fins and / or ribs 7a formed on the surface of the rotor 7.
Cet entrefer 18b constitue en fait la chambre de brassage et de propulsion du mélange des composants qui est propulsé vers le conduit d'évacuation 14 au cours de la rotation du rotor 7 entraîné par la seule induction électromagnétique.This air gap 18b in fact constitutes the mixing and propulsion chamber of the mixture of components which is propelled towards the evacuation duct 14 during the rotation of the rotor 7 driven by electromagnetic induction alone.
Le démontage de la chambre de mélange s'effectue en enlevant le flasque inférieur 4. Le changement du rotor 7, son montage et/ou son démontage deviennent des opérations simples, rapides et sûres facilitant le nettoyage de la chamde mélange. On doit noter que la tête mélangeuse peut être miniaturisée, désolidarisée du bâti machine, se déplacer dans toutes les directions de l'espace, prendre toutes les orientations exigées par la coulée, la projection, l'inJection du mélange, prendre la forme d'un pistolet. La chambre de mélange peut s'adapter à toutes les machines de coulée, de projection ou d'injection qu'elles soient de petites ou de grandes capacités, en marche continue ou discontinue. The disassembly of the mixing chamber is carried out by removing the lower flange 4. The change of the rotor 7, its assembly and / or disassembly become simple, rapid and safe operations facilitating the cleaning of the mixing chamber. It should be noted that the mixing head can be miniaturized, separated from the machine frame, move in all directions in space, take all the directions required by casting, projection, injection of the mixture, take the form of a gun. The mixing chamber can be adapted to all casting, spraying or injection machines, whether small or large, in continuous or discontinuous operation.
La chambre de mélange qui vient d'être décrite peut s'appliquer à des composants à l'état de gaz, de vapeur ou de liquide pour les mélanger dans des proportions définies et à des fins complémentaires éventuelles de dispersion, de dissolution, de réaction, d'adjonction de charges et/ou d'adjuvants spécifique tout en assurant la propulsion du mélange. The mixing chamber which has just been described can be applied to components in the state of gas, vapor or liquid in order to mix them in defined proportions and for possible complementary purposes of dispersion, dissolution, reaction , addition of fillers and / or specific additives while ensuring the propulsion of the mixture.
Diverses modifications et variantes peuvent être apportées aux dispositifs qui viennent d'être décrits sans sortir du cadre de la présente invention. Ainsi dans le cas où l'on désire que la chambre de mélange 5 assure elle-meme une propulsion énergique du mélange des composants, on peut disposer à la surface du rotor 7 de petites ailettes ou mieux des rainures hélicoidales orientées dans le sens assurant la propulsion du mélange du flasque supérieur 3 vers le flasque inférieur 4, les termes supérieur et inférieur étant bien entendu interchangeables. Dans une telle disposition, l'entrefer de mélange 18b peut être utilisé comme une simple pompe. Various modifications and variants can be made to the devices which have just been described without departing from the scope of the present invention. Thus in the case where it is desired that the mixing chamber 5 itself ensures energetic propulsion of the mixture of the components, it is possible to have on the surface of the rotor 7 small fins or better still helical grooves oriented in the direction ensuring the propulsion of the mixture from the upper flange 3 to the lower flange 4, the terms upper and lower being of course interchangeable. In such an arrangement, the mixing air gap 18b can be used as a simple pump.
On doit noter égaiement que dans certaines dispositions constructives de la chambre de mélange selon l'invention, la situation du stator et du rotor du moteur électrique peut être inversée. Dans ce cas, le stator I de la figure est mobile en rotation et le rotor 7 est fixe, et la chambre de mélange annulaire est alors constituée par la partie extérieure 18a de l'entrefer tandis que les ailettes de mélange et/ou de propulsion 7a sont reportées sur l'alésage intérieure du stator I de la figure (muni d'une cage d'écureuil), la canalisation 6 pouvant venir toucher la paroi lisse extérieure du rotor 7 de la figure. It should also be noted that in certain constructive arrangements of the mixing chamber according to the invention, the situation of the stator and of the rotor of the electric motor can be reversed. In this case, the stator I of the figure is movable in rotation and the rotor 7 is fixed, and the annular mixing chamber is then constituted by the external part 18a of the air gap while the mixing and / or propulsion fins 7a are transferred to the inner bore of the stator I of the figure (provided with a squirrel cage), the pipe 6 can come to touch the smooth outer wall of the rotor 7 of the figure.
