The present invention relates to a multi-jet (11) rotary nozzle (1) for the spraying of very fine abrasive particles (particle-size distribution ranging from 0 to 200 microns) having multiple acceleration conduit sections (4), comprising a body of revolution mounted on a rolling bearing (2) and comprising, in the direction of movement of the particles, a central bore (7) coaxial with the axis of revolution of the nozzle (1), this bore (7) branching out into a series of conduits (4), the direction of which makes an acute angle, at a given location, with the longitudinal axis of the nozzle (1) and the cross-section of which is firstly substantially constant (4) and then, subsequently, increases substantially in the direction of movement of the particles before emerging on the face (10) for spraying the particles. The multi-jet rotary nozzle finds its application particularly in the cleaning of façade-wall stone and for equipping the arm of a robot.

Description

BUSE ROTATIVE MULTI-JETS POUR LA PROJECTION DE
PARTICULES ABRASIVES TRES FINES
La présente invention concerne une buse rotative permettant de projeter un
ensemble de jets rotatifs multiples contenant des abrasifs de nettoyage fins ( 0 à
200 microns). Ces jets rotatifs multiples d'abrasifs trés fins permettent de nettoyer
la pollution encrassant la surface des monuments en pierre de taille sans abrasion..MULTI-JET ROTARY NOZZLE FOR PROJECTION OF
VERY FINE ABRASIVE PARTICLES
The present invention relates to a rotary nozzle for projecting a
set of multiple rotating jets containing fine cleaning abrasives (0 to
200 microns). These multiple rotating jets of very fine abrasives allow cleaning
pollution fouling the surface of stone monuments without abrasion.

Les dispositifs de projection rotatifs que l'on peut trouver sont des ensembles
trés lourds, tant au niveau du poids, qu'au niveau de la maniabilité. Ils ne sont pas
conçus pour être déplacés facilement et rapidemment dans tous les sens. Le but de
ces dispositifs lourds étant en plus de projeter des sables plus ou moins gros,
Ces dispositfs, ne disposent que de une à deux buses, et sont entrainés en
rotation sans moteur avec seulement la pression de l'air comprimé, nécessitant alors
des pressions de projections élevées. (Dispositif de sablage de canalisation, etc...)
La présente invention à donc pour but de remédier à tous ces inconvénients
et de proposer une buse rotative multi-jets pour la projection de particules abrasives
fines (0 à 200 microns )qui en plus est compacte, légère, peu volumineuse, et pouvant tourner mécaniquement et de façon fiable à de très grande vitesses de rotations ( 0 à 2000 tours par minutes), tout en projetant des jets multiples , et ce à faible pression ( 2 à 3 kilos )., et pouvant ainsi équiper le bras d'un robot.The rotary projection devices that can be found are sets
very heavy, both in terms of weight and handling. They are not
designed to be moved quickly and easily in any direction. The goal of
these heavy devices being in addition to projecting more or less large sands,
These devices, have only one to two nozzles, and are driven in
rotation without motor with only compressed air pressure, thus requiring
high projection pressures. (Pipe sanding device, etc.)
The present invention therefore aims to remedy all these drawbacks
and to propose a rotary multi-jet nozzle for the projection of abrasive particles
fine (0 to 200 microns) which is also compact, light, not very bulky, and capable of turning mechanically and reliably at very high rotational speeds (0 to 2000 revolutions per minute), while projecting multiple jets, and this at low pressure (2 to 3 kilos)., and thus being able to equip the arm of a robot.

Ainsi la présente invention est une buse rotative pour la projection de particules abrasives fines qui consiste en un ensemble multi-jets à sections de conduits d'accélérations multiples, comprenant un corps de révolution monté sur roulement et
comprenant dans le sens de déplacement des particules, un alésage central coaxial
à l'axe de révolution de la buse, cet alésage se ramifiant en une série de conduits
dont la direction forme un angle aigu à un endroit donné avec l'axe longitudinal de la buse et dont la section est d'abord sensiblement constante, puis croit ensuite
sensiblement et ce dans le sens de déplacement des particules avant de déboucher sur la face de projection des particules. Thus the present invention is a rotary nozzle for the projection of fine abrasive particles which consists of a multi-jet assembly with sections of multiple acceleration ducts, comprising a body of revolution mounted on a bearing and
comprising in the direction of movement of the particles, a coaxial central bore
to the axis of revolution of the nozzle, this bore branching into a series of conduits
the direction of which forms an acute angle at a given location with the longitudinal axis of the nozzle and the section of which is first substantially constant, then increases
substantially and this in the direction of movement of the particles before reaching the projection face of the particles.

Selon un mode de réalisation préférentiel:
Les conduits d'accélération 4 sont de sections fines, principalement situés
entre 2 et 4 millimétres. According to a preferred embodiment:
The acceleration ducts 4 are of thin sections, mainly located
between 2 and 4 millimeters.

Les abrasifs projetés sont des abrasifs de trés faibles granulométrie allant de (O à 200
microns ), mais ayant des caractéristiques de dureté trés importantes (micro-billes de
verre, corindon, etc...)
Cet ensemble de projection est une buse multi-jets 1l comprenant en
moyenne huit jets .Cette buse multi-jets 11 est montée dans un porte-buses 6 que l'on
entraine directement en rotation.Ce porte-buse est monté sur un jeu de roulements 2
Le porte-buse 6 contient:
Une buse multi-jets 1l comprenant un alésage central 7, coaxial à l'axe de révolution de la buse 1 Cet alésage se ramifie en une série de conduits d'accélération 4. L'entrée de ces conduits se fait par des cônes d'entrées larges.The projected abrasives are very small size abrasives ranging from (O to 200
microns), but having very important hardness characteristics (micro-balls of
glass, corundum, etc.)
This projection assembly is a 1l multi-jet nozzle comprising
eight jets on average. This multi-jet nozzle 11 is mounted in a nozzle holder 6 which is
directly rotates. This nozzle holder is mounted on a set of bearings 2
The nozzle holder 6 contains:
A multi-jet nozzle 11 comprising a central bore 7, coaxial with the axis of revolution of the nozzle 1 This bore branches out into a series of acceleration conduits 4. The entry of these conduits is by cones of wide entrances.

Les canaux d'accélération sont relativement longs pour donner une trés grande vitesse d'accélération aux particules à projeter. The acceleration channels are relatively long to give a very high speed of acceleration to the particles to be projected.

'Ces conduits d'accélération 4 se prolongent par des conduits d'éjection 5, dont la direction générale forme un angle aigu avec l'axe longitudinal de la buse 1 et dont la section croit dans le sens de déplacement des particules avant de déboucher sur la face de projection 10 des particules. La section de ces conduits d'éjection varie d'une forme sensiblement circulaire à une forme oblongue au niveau de son ouverture de sortie sur la face de projection des particules 10. 'These acceleration conduits 4 are extended by ejection conduits 5, the general direction of which forms an acute angle with the longitudinal axis of the nozzle 1 and the cross section of which increases in the direction of movement of the particles before leading to the projection face 10 of the particles. The section of these ejection conduits varies from a substantially circular shape to an oblong shape at its outlet opening on the projection face of the particles 10.

Ces conduits d'éjection 5 ont préférentiellement une forme de sortie sensiblement en arc de cercle 14, et sont centrés sur l'axe longitudinal de la buse,et permettant ainsi de par le mouvement rotatif, d'accentuer l'effet de projection étalée. These ejection conduits 5 preferably have an outlet shape substantially in an arc 14, and are centered on the longitudinal axis of the nozzle, and thus making it possible, by the rotary movement, to accentuate the effect of spreading projection.

Les ouvertures de sortie de la buse vus selon la face de projection 10 s'inscrivent sensiblement dans une spirale.  The outlet openings of the nozzle seen along the projection face 10 are substantially in a spiral.

Les buses de projection 7 au niveau des conduits d'éjections 5 ne débordent pas ou pratiquement pas de la face de projection 10
La buse 1 et son porte buse 6 monté directement sur un jeu de roulements
est compactée dans un bloc carter 13 de maintien étanche et est équipée d'un joint d'étanchéité.The projection nozzles 7 at the level of the ejection conduits 5 do not project or practically do not project from the projection face 10
Nozzle 1 and its nozzle holder 6 mounted directly on a set of bearings
is compacted in a waterproof holding casing block 13 and is fitted with a seal.

Cet ensemble buse multi-jets 11 est équipée d'un moteur 8 de rotation à vitesses élevées ( 0 à 2000 tours). Cette vitesse de rotation est une vitesse variable. This multi-jet nozzle assembly 11 is equipped with a motor 8 of rotation at high speeds (0 to 2000 revolutions). This rotational speed is a variable speed.

Préférentiellement l'axe du moteur se trouve sensiblement dans l'axe de révolution de la buse. Preferably, the axis of the motor is located substantially in the axis of revolution of the nozzle.

Dans des formes de réalisation préférentielles, cet ensemble buse multi-jets
comprend des moyens de projection d'eau disposés autour de la buse 1 de manière à former un rideau d'eau annulaire autour des jets de projections d'abrasifs.In preferred embodiments, this multi-jet nozzle assembly
comprises water spraying means arranged around the nozzle 1 so as to form an annular water curtain around the abrasive spray jets.

Cet ensemble buse rotative multi-jets (11) est équipée de points de réglage permettant: la marche arrêt de l'envoie du mélange air-poudre, la marche arrêt du
moteur de rotation (8), de modifier des plages de vitesses présélectionnées, de modifier des débits présélectionnés.This multi-jet rotary nozzle assembly (11) is equipped with adjustment points allowing: the on-off of the sending of the air-powder mixture, the on-off of the
rotation motor (8), to modify preselected speed ranges, to modify preselected flow rates.
