Definitions

  • the invention relates to a spray device, commonly referred to as a spray bowl, intended to spray a liquid coating product into fine droplets; it applies in particular to the spraying of any type of paint or varnish, liquid.
  • the invention also relates to any sprayer with a rotating head, equipped with such a spraying device.
  • the invention applies preferentially to a sprayer with a very high speed of rotation, typically of the order of 50,000 to 100,000 revolutions per minute.
  • the patent US 2658472 describes a spray bell inside which there are liquid ejection nozzles directed towards the distribution surface. The presence of these nozzles disturbs the rotational drive of the volume of air inside the spray bell. In addition, the nozzles deposit the liquid at a very short distance from the spray edge, which is unfavorable to a good spreading of the liquid on said distribution surface, before it is sprayed on the edge of the bell.
  • the invention proposes a rotary spray device having a combination of several characteristics which combine to obtain a finer spray, with an extremely narrow diameter distribution of the droplets, making it possible to obtain, in the case in particular of a paint, a better aspect of the deposit.
  • the invention relates to a device for spraying liquid coating product according to claim 1.
  • trumpet shape of this surface is favorable to good cleaning using a liquid cleaning product injected instead of the liquid to be sprayed. More precisely, this surface has no discontinuity that could lead to an undesirable accumulation of certain components of the liquid to be sprayed, in particular certain pigments.
  • the spray edge can be a sharp or notched edge. Streaks can be printed in this surface, in the vicinity of the spraying edge, or placed on the distribution surface.
  • the profile of the distribution surface along a half-section passing through the axis of rotation of said rotary bowl has substantially the shape of an exponential.
  • fast growth we mean any function whose derivative grows with the variable. It is also possible to adopt as profile a section of hyperbolic function. Any linear combination of these types of curves is also suitable.
  • any rotating spray bowl combining a central supply (that is to say an axial injection of liquid, in the hub) with a distribution surface of the type described above, is within the scope of the invention. .
  • the bowl comprises a distributor mounted in the axial extension of said hub, extending to the bottom of said deflector and comprising a core obstructing the axial flow of the liquid and radial passages arranged at the rear of said core to directing at least the greater part of the flow of liquid towards said distribution surface.
  • a liquid spray device 11 comprising an element of revolution 12 intended to be driven in rotation, at relatively high speed around a main axis x′ x.
  • This device is particularly suitable for the electrostatic spraying of liquid coating products such as paints or varnishes.
  • the element of revolution 12 consists essentially of an axial, tubular hub 13, extended forwards by a divergent centrifugal deflector 14 having a circular spray edge 15 .
  • the hub 13 constitutes or houses a liquid supply conduit. The liquid to be sprayed propagates forwards until it reaches a continuous distribution surface 18 extending between the hub and the spray edge.
  • the hub 13 is intended to be mounted at the end of a hollow shaft of a drive device, not shown.
  • this drive device is a compressed air turbine.
  • the liquid to be sprayed is introduced by an injector 17 placed in the hollow shaft of this turbine and in the hub. It flows forwards spreading over said distribution surface 18.
  • Said hub 13 has a thread 20 by which it can be fixed to the shaft of the turbine.
  • the attachment may be magnetic as described in the document EN 2805182 .
  • Said distribution surface 18 has the overall shape of a trumpet horn and the liquid emerging from the hub 13, more precisely here from the injector 17, is distributed in a thin film on the distribution surface while progressing to the edge of spraying where it is atomized into fine droplets, under the effect of centrifugal force.
  • the centrifugal deflector 14 is at least partially made of electrically conductive material. It is generally placed at a high negative electrical potential, close to 100 kV, and the object to be painted is placed at ground potential.
  • the latter may for example be made of metal, or internally covered with an electrically conductive layer.
  • the action of the high electric field, in the vicinity of the spray edge 15, also contributes, like the effect of the centrifugal force, to breaking the thin film into fine droplets.
  • a continuous profile of the centrifugal divergent deflector such as that given by a trumpet shape, makes it possible, due to its large radius of curvature, to concentrate the electric field in the zone having the smallest radius of curvature, that is to say i.e. on the spray edge, precisely where the droplets are formed by essentially mechanical effect.
  • the trumpet shape is therefore favorable to all the means which contribute to the good spraying of the liquid on the spraying edge, that is to say a mechanical effect and an electrostatic effect.
  • the distribution surface 18 has the overall shape of a trumpet bell. In other words, said distribution surface generally has a certain convexity directed towards the object to be covered. Typically, the distribution surface along a half-section passing through the axis of rotation has here substantially the shape of an exponential.
  • the element of revolution 12 composed of the hub and the centrifugal deflector houses means for substantially radially deflecting part of the liquid towards the innermost part of the distribution surface 18.
  • These means consist of a distributor 22 mounted in the extension axial of the hub 13 and partly extending to the bottom of the deflector 14.
  • This distributor has the function of deflecting the liquid introduced axially so that the greater part of the flow of liquid is directed towards the distribution surface 18 in the zone la more internal to it.
  • This distributor 22 comprises a core 24 obstructing the axial flow of the liquid. It is provided with radial passages 26 arranged at the rear of the core.
  • the core 24 comprises a lateral surface of revolution 28 extending opposite and at a distance from the distribution surface 18, in the innermost zone of the latter, to define with said surface an annular passage 30 extending said radial passages.
  • the distributor 22 comprises a tubular element of revolution 32, of which a mounting portion 34, rear, is fixed inside the axial hub 13.
  • the injector 17 ends in a nozzle engaged in the axial cavity of the mounting portion 34, opposite the rear face of the core 24.
  • the radial passages 26 are constituted by three cutouts made in the element 32 between said mounting portion and the core 24. In fact, these three cutouts do not leave in the element 32 that three bridges 36 circumferentially offset at 120 degrees from each other and connecting said mounting portion 34 to the core 24.
  • the greater part of the liquid injected axially by the hub 13 passes through the element 32 until coming to strike the rear face of the core 24 and continues its flow radially until it meets the distribution surface 18 on which it spreads while progressing forwards to the spray edge 15.
  • the most central part of the deflector is lined internally with an annular wear part 50 integrated into the innermost part of the distribution surface 18. More particularly, the visible, inner surface of this annular part marries and extends the distribution surface 18 without any break in continuity. It is generally located radially on the outside and opposite the radial passages 26.
  • This annular wear part can be fitted into the bottom of the deflector. In this case, it is planned to be replaced regularly.
  • the annular part can on the contrary be made of a material that is very resistant to abrasion (ceramic, hard metal, etc.) or at least its internal surface, facing the radial passages 26, can be covered with a material abrasion resistant, for example titanium nitride.
  • at least the innermost part of the distribution surface 18 (that is to say that which faces the passages 26) is covered with a layer of material resistant to abrasion.
  • the core 24 comprises four divergent channels 38 extending between the rear surface thereof and an annular abutment surface 39 surrounding an axial passage 40 extending in a front part of said core.
  • This comprises a first insert 44 fixed in the front part of the distributor, more particularly at the front of the element 32.
  • the annular abutment surface 39 extending opposite the orifices of the divergent channels 38 and the axial passage 40 which extends this annular abutment surface are defined in the insert 44.
  • a cylindrical housing, defined at the rear of the stopper, houses a second insert 46 containing the four divergent channels.
  • the distributor 22 that is to say more particularly the element of revolution 32, is force-fitted inside the hub 13 while the first insert 44 is itself force-fitted in the front part of said distributor.
  • the insert 46 is for its part mounted by force in the insert 44. All these elements can be made of plastic or metal. Operation is as follows.
  • the liquid When the liquid is introduced under pressure into the injector 17, it strikes the rear face of the core 24 and is partly deflected radially to the bottom of the distribution surface 18. The liquid continues to spread, under the effect of centrifugal force, on this surface forming an increasingly thin thin film as it progresses towards the edge of the spray. When the liquid reaches the spray edge, it is sprayed into fine droplets.
  • a small part of the liquid enters the divergent channels 38 and strikes the annular abutment surface 39.
  • This secondary flow of liquid bypasses the rounded surface 42 of the axial passage 40 without being projected forwards and progresses radially towards the exterior on the front surface of the dispenser until it joins the main flow of liquid flowing along the distribution surface 18.
  • the front of the dispenser is constantly wetted with liquid. If the liquid is paint or varnish, there is therefore no risk of it drying on the surface of the dispenser.
  • the spray device can easily be cleaned by injecting a cleaning liquid instead of the liquid coating product.
  • the ratio between the maximum diameter of the distributor 22 and the diameter of the spray edge 15 can be between 5 and 60%. Preferably, this ratio will be between 10 and 40%.
  • the diameter of the spray edge is generally between 25 and 100 mm.
  • any liquid sprayer in particular any paint or varnish sprayer, characterized in that it comprises a spraying device as described above.
  • a sprayer generally consists of a drive device in rotation, such as for example a compressed air turbine, carrying the spraying device and arranged to allow axial injection of liquid to be sprayed inside the hub.
  • This sprayer is generally supplemented by a high voltage power supply carrying the centrifugal deflector 14 (conductive, for example metallic) to a high voltage.
  • the speed of rotation can be from 50,000 to 100,000 rpm and the device which has just been described is remarkable for its ability to give a very fine and very regular spray (small difference in droplet size) , this in a very wide range of rotational speeds.
