La présente invention concerne un dispositif pour créer un jet fluide orbital pur ou chargé de particules abrasives capable de réaliser des opérations de traitement de surface comme l'arrosage, le décapage, le grenaillage, le nettoyage, le sablage, le séchage ou autre... The present invention relates to a device for creating a pure or abrasive-charged orbital fluid jet capable of carrying out surface treatment operations such as watering, stripping, shot blasting, cleaning, sanding, drying or other. .
Traditionnellement, ces opérations de traitement de surface jet rond ou à jet plat. Ces faibles taux de recouvrement, surface traitée par unité de selon l'invention permet de remédier à cet au bout d'une buse, ce nouveau dispositif jet provenant de cette buse d'un mouvement orbital, et ce, quelle que soit la nature du jet fluide, chargé ou non de particules abrasives. Ainsi, grâce au mouvement orbital du jet, l'aire de la surface traitée par unité de temps augmente. Traditionally, these round jet or flat jet surface treatment operations. These low coverage rates, surface treated per unit of the invention can remedy this at the end of a nozzle, this new jet device from this nozzle of an orbital movement, and whatever the nature of the fluid jet, loaded or not with abrasive particles. Thus, thanks to the orbital motion of the jet, the area of the treated surface per unit of time increases.
Ce dispositif comporte selon une première caractéristique un rotor relié à un corps par une liaison pivot, ce corps étant lui même fixé à la buse. Le rotor présente une conduite(C) dont la géométrie permet: Éd'une part, de dévier le jet provenant de la buse, dont l'axe d'écoulement est l'axe(Z), d'un angle(a), Éd'autre part, grâce aux bras de levier(R) entre le point d'application des forces hydrodynamiques exercées par le jet sur la conduite(C) et l'axe(Z), d'assurer un moment de ces forces hydrodynamiques par rapport à l'axe(Z) différent de zéro. This device comprises according to a first characteristic a rotor connected to a body by a pivot connection, this body being itself fixed to the nozzle. The rotor has a pipe (C) whose geometry allows: On the one hand, to deflect the jet coming from the nozzle, whose axis of flow is the axis (Z), of an angle (a), On the other hand, thanks to the lever arms (R) between the point of application of the hydrodynamic forces exerted by the jet on the pipe (C) and the axis (Z), to ensure a moment of these hydrodynamic forces by relative to the axis (Z) other than zero.
Compte tenu de la liaison pivot qui relie le rotor au corps, ledit rotor se met en rotation par rapport au corps sous l'effet de ce moment. Ainsi, on obtient un jet orbital en sortie du dispositifE produisant un impact annulaire sur la surface à traiter. Given the pivot connection which connects the rotor to the body, said rotor is rotated relative to the body under the effect of this moment. Thus, an orbital jet is obtained at the output of device E producing an annular impact on the surface to be treated.
Plusieurs géométries de conduite(C) peuvent satisfaire ce principe de fonctionnement dévier le jet tout en assurant un 35 moment ou couple par rapport à l'axe Z différent de zéro . A titre d'exemple non limitatif, je cite: Éune conduite en spirale, en hélice ou torsadé,(FIG.2) sont effectuées à l'aide de buses buses de projection présentent de le taux de recouvrement étant la temps. Several driving geometries (C) can satisfy this operating principle to deflect the jet while providing a moment or torque with respect to the Z axis other than zero. By way of non-limiting example, I quote: A spiral, helical or twisted pipe, (FIG. 2) are made using nozzles projection nozzles have the recovery rate being the time.

Fixé permet d'animer le - 2 Éune conduite composée de plusieurs tronçons de géométrie simple, raccordés les uns aux autres,(FIG.4 et FIG.5) 40 Éun rotor contenant des pales ou aubes, Selon des modes particuliers de réalisation: le rotor peut comporter une, deux ou plusieurs conduites(C1, C2,...,C,) produisant ainsi un ou plusieurs jets orbitaux. The disadvantage device. Fixed allows to animate the - 2 Éa pipe composed of several sections of simple geometry, connected to each other, (FIG.4 and FIG.5) 40A rotor containing blades or blades, According to particular embodiments: the rotor may comprise one, two or more conduits (C1, C2, ..., C,) thereby producing one or more orbital jets.
- le rotor étant exposé à l'impact du jet fluide pur ou chargé de particules, donc sujet à une usure importante, pourrait être protégé selon les solutions suivantes: Éle rotor est réalisé en entier dans un matériau résistant à l'érosion abrasion, Éla conduite(C) est revêtue d'une couche de matériau 50 résistant à l'érosion-abrasion, Éle rotor est réalisé en deux parties: un canon de focalisation réalisé dans un matériau résistant à l'érosion-abrasion et un porte-canon dans un autre matériau. the rotor being exposed to the impact of the pure fluid jet or charged with particles, thus subject to significant wear, could be protected according to the following solutions: The rotor is made entirely in an abrasion resistant material abrasion, Ela The pipe (C) is coated with a layer of erosion-abrasion-resistant material 50. The rotor is made in two parts: a focusing gun made of an erosion-abrasion resistant material and a gun holder in another material.
- le dispositif pourrait être équipé d'un frein pour ralentir le rotor et ainsi réguler sa vitesse de rotation. - The device could be equipped with a brake to slow down the rotor and thus regulate its speed of rotation.
Les dessins annexés illustrent l'invention: La figure 1 représente un schéma du dispositif de l'invention La figure 2 représente un schéma du rotor et de la conduite(C) La figure 3 représente le parcours du jet dans la conduite(C) La figure 4 représente un rotor avec une conduite cônecylindre La figure 5 représente un rotor avec conduite cylindre-cylindre La figure 6 représente un rotor comportant deux conduites La figure 7 représente un rotor en deux parties La figure 8 représente une buse jet d'eau pur orbital La figure 9 représente une buse jet d'eau abrasif orbital La figure 10 représente une buse de sablage orbital En référence aux figures 1, 2 et 3, le dispositif, fixé à la buse(l), comporte un corps(2) relié par une liaison pivot(3) au rotor(4). Ledit rotor(4) est muni d'une conduite(C) dont la géométrie permet d'une part la déviation du jet(5) de son axe d'écoulement(Z) d'un angle(a) et d'autre part la mise en rotation dudit rotor(4) autour de l'axe(Z). En effet, grâce au bras de levier(R), la perte de charge du jet(5) occasionnée dans la - 3 conduite(C) est transformée en moment par rapport à l'axe(Z). Compte tenu de la liaison pivot(3) entre le rotor(4) et le corps(2), liaison matérialisée par des roulements, coussinets ou autre, ledit rotor(4) se met en rotation par rapport au corps(2) autour de l'axe(Z) sous l'effet de ce moment. Il en résulte un jet orbital. The attached drawings illustrate the invention: FIG. 1 represents a diagram of the device of the invention FIG. 2 represents a diagram of the rotor and the pipe (C) FIG. 3 represents the path of the jet in the pipe (C) Fig. 5 shows a rotor with a cylinder-cylinder line; Fig. 6 shows a rotor with two lines; Fig. 7 shows a two-piece rotor; Fig. 8 shows a jet nozzle with pure orbital water FIG. 9 represents an orbital abrasive water jet nozzle FIG. 10 represents an orbital sand blasting nozzle. With reference to FIGS. 1, 2 and 3, the device, attached to the nozzle (1), comprises a body (2) connected by a pivot connection (3) to the rotor (4). Said rotor (4) is provided with a pipe (C) whose geometry allows firstly the deflection of the jet (5) of its axis of flow (Z) by an angle (a) and secondly rotating said rotor (4) about the axis (Z). Indeed, thanks to the lever arm (R), the pressure drop of the jet (5) caused in the - 3 line (C) is transformed in time relative to the axis (Z). Taking account of the pivot connection (3) between the rotor (4) and the body (2), link materialized by bearings, bushings or the like, said rotor (4) is rotated relative to the body (2) around the axis (Z) under the effect of this moment. This results in an orbital jet.
Selon la figure 4, le rotor(4) comporte une conduite(C) composée d'un tronçon conique (T1) d'angle(P) en entrée, suivi d'un tronçon cylindrique(T2) incliné d'un angle(a) vers la sortie. Selon le principe de fonctionnement explicité ci-dessus, le jet(5) provenant de la buse(l) impacte la paroi conique (T1) au point(P1), se trouve ensuite dévié vers la paroi cylindrique(T2) et l'impacte au point(P2) avant de quitter le rotor(4). Grâce au bras de levier(R), le moment des forces(F1) et (F2) résultant des interactions aux points(P1) et (P2) du jet(5) avec les deux tronçons (T1) et (T2) du rotor(4) par rapport à l'axe(Z) est différent de zéro. According to FIG. 4, the rotor (4) comprises a pipe (C) composed of a conical section (T1) of angle (P) at its entrance, followed by a cylindrical section (T2) inclined at an angle (a) ) to the exit. According to the operating principle explained above, the jet (5) coming from the nozzle (1) impacts the conical wall (T1) at the point (P1), is then deflected towards the cylindrical wall (T2) and the impact at point (P2) before leaving the rotor (4). Thanks to the lever arm (R), the moment of the forces (F1) and (F2) resulting from the interactions at the points (P1) and (P2) of the jet (5) with the two sections (T1) and (T2) of the rotor (4) with respect to the axis (Z) is different from zero.
Le dess__n de la figure 5 représente une configuration du rotor(4) où la conduite(C) est composée de deux tronçons cylindriques(T3) et (T4) raccordés l'un à l'autre comme représentés sur la figure 5; le tronçon(T3) d'inclinaison(a3) débouche dans le tronçon (Tq) d'inclinaison(a4) . Le jet(5) attaque le rotor(4) par le tronçon (T3) et l'impacte au point(P3) . Le jet(5) arrive ensuite dans le tronçon(T4) et l'impacte au point(PQ) avant de quitter le rotor(4). Le moment par rapport à l'axe(Z) des forces hydrodynamiques résultant de l'écoulement du jet(5) dans les tronçons(T3) et (T9) est différent de zéro. The drawing of Figure 5 shows a configuration of the rotor (4) where the pipe (C) is composed of two cylindrical sections (T3) and (T4) connected to each other as shown in Figure 5; the inclination section (T3) (a3) opens into the inclination section (Tq) (a4). The jet (5) attacks the rotor (4) by the section (T3) and impacts it at the point (P3). The jet (5) then arrives in the section (T4) and impacts it at the point (PQ) before leaving the rotor (4). The moment relative to the axis (Z) of the hydrodynamic forces resulting from the flow of the jet (5) in the sections (T3) and (T9) is different from zero.
Dans la forme de réalisation selon la figure 6, le rotor(4) comporte deux conduites(C1) et (C2) inclinées respectivement de (al) et (a2) et raccordés l'une à l'autre comme représentées sur la figure 6. Le jet(5) provenant de la buse(l) impacte le rotor(4) au point(PS) et se trouve divisé en deux jets distincts. L'écoulement de ces deux jets dans le conduites(C1) et (C2) produit un couple autour de l'axe(Z) grâce au bras de levier(R). Ce type de rotor produit deux jets orbitaux. Plus généralement, un rotor peut comporter une, deux ou plusieurs conduites(Cn) produisant ainsi un, deux ou plusieurs jets orbitaux. In the embodiment according to FIG. 6, the rotor (4) comprises two lines (C1) and (C2) inclined respectively of (a1) and (a2) and connected to one another as shown in FIG. The jet (5) from the nozzle (1) impacts the rotor (4) at the point (PS) and is divided into two separate jets. The flow of these two jets in the pipes (C1) and (C2) produces a torque around the axis (Z) through the lever arm (R). This type of rotor produces two orbital jets. More generally, a rotor may comprise one, two or more pipes (Cn) thus producing one, two or more orbital jets.
Le dessin de la figure 7 représente un rotor(4) en deux parties; la première partie est un canon de déviation(R1) réalisé dans un matériau résistant à l'érosion-abrasion et la deuxième partie est un portecanon(R2) réalisé dans un autre matériau. The drawing of Figure 7 shows a rotor (4) in two parts; the first part is a deflection gun (R1) made of an erosion-abrasion resistant material and the second part is a portecanon (R2) made of another material.
Le dispositif permet de créer des jets orbitaux, et ce, quelle que soit la nature du jet(5) provenant de la buse(?) : jet d'eau pur, jet d'eau abrasif, jet d'air, jet d'air chargé de particules, jet air-eau et particules... A titre d'exemple non limitatif, les figures 8, 9 et 10 montrent différentes utilisations du dispositif de l'invention: -Selon la figure 8, le dispositif est fixé, grâce au filetage entre la buse(l) et le corps(2), sur la buse(l) fournissant un jet d'eau pure(5). L'interaction du jet d'eau pure(5) avec le rotor(4) qui est relié au corps(2) par la liaison pivot(3) produit en sortie du dispositif un jet d'eau pur orbital. -Selon la figure 9, le dispositif est vissé, grâce à l'écrou (6) , sur une buse(?) fournissant un jet d'eau abrasif(5). The device makes it possible to create orbital jets, whatever the nature of the jet (5) coming from the nozzle (?): Jet of pure water, jet of abrasive water, jet of air, jet of air charged particles, air-water jet and particles ... By way of non-limiting example, Figures 8, 9 and 10 show different uses of the device of the invention: -Selon Figure 8, the device is fixed, thanks to the threading between the nozzle (1) and the body (2), on the nozzle (1) providing a jet of pure water (5). The interaction of the pure water jet (5) with the rotor (4) which is connected to the body (2) by the pivot connection (3) produces at the outlet of the device a stream of pure orbital water. According to FIG. 9, the device is screwed, thanks to the nut (6), onto a nozzle (?) Providing an abrasive water jet (5).
L'interaction du jet d'eau abrasif(5) avec le rotor(4) qui est relié au corps(2) par la liaison pivot(3) produit en sortie du dispositif un jet d'eau abrasif orbital. The interaction of the abrasive water jet (5) with the rotor (4) which is connected to the body (2) by the pivot connection (3) produces at the outlet of the device an orbital abrasive water jet.
-Dans la figure 10, le dispositif est fixé grâce à plusieurs vis de serrage(6) à une buse(?) fournissant un jet de sablage(5). In FIG. 10, the device is fixed by means of several clamping screws (6) to a nozzle (?) Providing a sanding jet (5).
L'interaction du jet(5) avec le rotor(4) qui est relié au corps(2) par la liaison pivot(3) produit en sortie du dispositif un jet de sablage orbital. The interaction of the jet (5) with the rotor (4) which is connected to the body (2) by the pivot connection (3) produces at the outlet of the device an orbital sandblasting jet.
Selon une variante non illustrée, le dispositif peut être équipé d'un frein pour ralentir le rotor(4) et ainsi réguler sa 140 vitesse de rotation. According to a variant not illustrated, the device may be equipped with a brake to slow down the rotor (4) and thus regulate its speed of rotation.
