Description
La présente invention concerne un dispositif qui délivre "N" jets fluides orbitaux, chargés ou non de particules, destiné à la réalisation d’applications telles que l’arrosage, le lavage, le nettoyage, le massage, le gommage, le décapage, le grenaillage, le polissage, le sablage, le séchage, le peinturage... Le nombre "N" de jets orbitaux (JOPQ) délivrés par ce dispositif est supérieur ou égal à 1 (N ≥ 1) et s’écrit : N = P.Q où le nombre de toupies (TP) est P ≥ 1 et le nombre de canaux (CPQ) dans une toupie est Q ≥ 1.The present invention relates to a device which delivers "N" orbital fluid jets, charged or not with particles, intended for the performance of applications such as watering, washing, cleaning, massage, exfoliation, pickling, shot blasting, polishing, sandblasting, drying, painting... The number "N" of orbital jets (JO PQ ) delivered by this device is greater than or equal to 1 (N ≥ 1) and is written: N = PQ where the number of spinning tops (T P ) is P ≥ 1 and the number of channels (C PQ ) in a spinning top is Q ≥ 1.
Il existe divers dispositifs de projection fluidique, mono-jet ou multi-jets, à jet orbital ou non orbital, chargés ou non de particules, comme les pommeaux de douche, pistolets, lances et buses de projection... Les dispositifs à jet orbital mettent en œuvre un jet orbital produisant un impact annulaire permettant : (i) de traiter des surfaces plus grandes et (ii) d’avoir des impacts sur la cible plus énergiques et efficaces. Ces dispositifs à jet orbital présentent des performances techniques et des coûts d’exploitation intéressants.There are various fluidic projection devices, mono-jet or multi-jet, orbital or non-orbital jet, charged or not with particles, such as shower heads, spray guns, lances and projection nozzles... Orbital jet devices implement an orbital jet producing an annular impact allowing: (i) to treat larger surfaces and (ii) to have more energetic and effective impacts on the target. These orbital jet devices have attractive technical performance and operating costs.
Le dispositif de projection fluidique, selon le document portant la référence FR 2 934 508 A1 (RAISSI KADDOUR [FR]), met en œuvre plusieurs jets orbitaux à la fois, accroissant ainsi les performances de traitement. Ces jets orbitaux sont obtenus suivant la solution de la figure
Seulement, étant donné les conditions de son utilisation dans un environnement agressif et non propre, l’exposant à des écoulements fluidiques chargés ou non de particules, ce dispositif est confronté à des problèmes d’encrassement et de frottement au niveau des parties tournantes. Des dépôts de tartre et corrosion apparaissent au niveau des paliers lisses ou à roulements, engendrant du frottement et une résistance au pivotement desdits rotors. L’utilisation de roulements étanches n’améliore pas la situation, car les frottements générés par les flasques perturbent fortement la rotation du rotor (RP).Only, given the conditions of its use in an aggressive and not clean environment, exposing it to fluid flows charged or not with particles, this device is confronted with problems of fouling and friction at the level of the rotating parts. Scale and corrosion deposits appear on the plain or roller bearings, causing friction and resistance to the pivoting of said rotors. The use of sealed bearings does not improve the situation, since the friction generated by the flanges strongly disturbs the rotation of the rotor (R P ).
Ces encrassements systématiques des paliers lisses ou à roulements, engendrant du frottement qui bloque la rotation des rotors, rendent le dispositif (référence FR 2 934 508 A1) non fiable et non robuste, empêchant toute possibilité d’exploitation industrielle et lui fermant les portes des marchés.This systematic fouling of the plain or rolling bearings, generating friction which blocks the rotation of the rotors, makes the device (reference FR 2 934 508 A1) unreliable and unrobust, preventing any possibility of industrial exploitation and closing the doors of the markets.
Le dispositif selon l’invention permet de remédier aux problèmes présentés ci-dessus en proposant une nouvelle solution fiable et robuste de production de jets orbitaux et ce même en présence de fluides chargés ou non de particules et malgré les encrassements des parties tournantes par des dépôts comme le tartre, par exemple. Ainsi de nouvelles perspectives et opportunités d’exploitation industrielle du dispositif selon l’invention deviennent possibles.The device according to the invention makes it possible to remedy the problems presented above by proposing a new reliable and robust solution for the production of orbital jets, even in the presence of fluids laden or not with particles and despite the fouling of the rotating parts by deposits. like tartar, for example. Thus new perspectives and opportunities for industrial exploitation of the device according to the invention become possible.
Ce dispositif propose une nouvelle solution de production de jets orbitaux sans paliers lisses ni roulements, paliers jugés très sensibles à l’encrassement dans un contexte agressif et non propre. Cette nouvelle solution s’inspire de l’exemple de la toupie qui tourne sur sa pointe autour de son axe de rotation jusqu’à ce que le frottement, très faible, l’arrête.This device offers a new solution for producing orbital jets without plain bearings or bearings, bearings considered to be very sensitive to fouling in an aggressive and unclean environment. This new solution is inspired by the example of the spinning top which turns on its tip around its axis of rotation until the very low friction stops it.
Ainsi, le dispositif selon l’invention est muni de "P" toupies (TP), de géométrie particulière car possédant chacune une pointe inférieure et une pointe supérieure,
Le dispositif selon l’invention, présenté ci-dessus, fonctionne comme suit,
Compte tenu de la géométrie particulière des canaux (CPQ), qui se déploient en étoile depuis l’entrée (EP), située sur le sommet de chaque rotor (RP) et centrée sur l’axe (ZP), jusqu’aux sorties (SPQ) situées à la périphérie de la base dudit rotor (RP), en suivant une trajectoire hélicoïdale,
Le choix des matériaux composant la toupie (TP) ainsi que le siège (BP) et le guide (DP) conditionnent fortement la rotation de ladite toupie (TP) et par conséquent le fonctionnement du dispositif selon l’invention. Ainsi, pour garantir la fiabilité et la robustesse de ce dispositif, ces matériaux doivent présenter une bonne tenue mécanique et résistance à l’oxydation et assurer un bon glissement et roulement au niveau des surfaces de contact entre la toupie (TP), le siège (BP) et le guide (DP).The choice of materials making up the top (T P ) as well as the seat (B P ) and the guide (D P ) strongly condition the rotation of said top (T P ) and consequently the operation of the device according to the invention. Thus, to guarantee the reliability and robustness of this device, these materials must have good mechanical strength and resistance to oxidation and ensure good sliding and rolling at the level of the contact surfaces between the top (T P ), the seat (B P ) and the guide (D P ).
En résumé, le dispositif selon l’invention met en œuvre une solution fiable et robuste pour produire "N" jets orbitaux (JOPQ), même en présence de fluides chargés ou non de particules et malgré les encrassements. Le dispositif selon l’invention dispose de "P" toupies (TP), chacune composée d’un rotor (RP) encastré sur un arbre (AP). Chaque toupie de ce dispositif comprend une entrée annulaire (EP) donnant sur des canaux (CPQ) de géométrie hélicoïdale aboutissant aux sorties (SPQ) situées à la périphérie de la base dudit rotor (RP). La mise en position et maintien de chaque toupie (TP) se font grâce au siège (BP) et le guide (DP) où sont logées les pointes de ladite toupie (TP).In summary, the device according to the invention implements a reliable and robust solution for producing "N" orbital jets (JO PQ ), even in the presence of fluids laden or not with particles and despite fouling. The device according to the invention has "P" spinning tops (T P ), each composed of a rotor (R P ) embedded on a shaft (A P ). Each spinning top of this device comprises an annular inlet (E P ) opening onto channels (C PQ ) of helical geometry leading to the outlets (S PQ ) located at the periphery of the base of said rotor (R P ). Positioning and holding each spinning top (T P ) is done using the seat (B P ) and the guide (D P ) where the tips of said spinning top (T P ) are housed.
