Definitions
- the invention relates to a spraying device, commonly called 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 rotary head sprayer equipped with such a spraying device.
- the invention preferably applies to a sprayer with a very high speed of rotation, typically of the order of 50,000 to 100,000 revolutions per minute.
- Numerous types of spraying device for coating product in the form of a bowl or bell are known, rotating at high speed.
- the product to be sprayed flows on the inside surface of the bowl and, under the effect of centrifugal force, reaches the edge of the bowl where it is sprayed into fine droplets.
- the bowl is most often shaped so that the surface facing the object to be covered is generally concave, often frustoconical.
- document EP 0951942 describes a bowl with a frustoconical distribution surface.
- the document US 692631 describes a rotary and electrostatic device with external charge for dispersing a liquid in threads, forming textile fibers as the liquid solidifies in the air by dispersion and evaporation of its most volatile components. Fibers form beyond the rotating device because the liquid is subjected to an electric field created between two electrodes located downstream of the rotating device. This document does not concern the electrostatic spraying of liquid coating product. In addition, the speed of rotation is insufficient to spray the liquid by the sole effect of centrifugal force. The liquid is in the form of a thin layer when it enters the zone where the electric field prevails.
- US Pat. No. 2,658,472 describes a spray bell inside which there are liquid ejection nozzles directed towards the distribution surface. The presence of these nozzles disturbs the rotation drive of the air volume inside the spray bell. In addition, the nozzles deposit the liquid at a very short distance from the spraying edge, which is unfavorable for good spreading of the liquid on said distribution surface, before being sprayed on the edge of the bell.
- the invention provides a rotary spraying device having a combination of several characteristics which combine to obtain a finer spraying, with an extremely tight distribution of droplet diameter, 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 a liquid coating product
- a divergent centrifugal deflector having a spraying edge and capable of being driven in rotation about an axis of rotation, characterized in that it comprises a tubular hub forming or housing a liquid supply duct, in that said centrifugal deflector comprises a continuous distribution surface extending between said hub and said spraying edge, in that this distribution surface is generally in the form of a horn of a trumpet and in that it comprises means for deflecting at least radially at least part of said liquid towards the innermost part of said distribution surface in the shape of a horn of a trumpet.
- trumpet shape of this surface is favorable for good cleaning using a liquid cleaning product injected in place of the liquid to be sprayed. More precisely, this surface has no discontinuity which could lead to an undesirable accumulation of certain components of the liquid to be sprayed, in particular certain pigments.
- the spraying edge can be a sharp or notched edge. Streaks can be printed in this surface, in the vicinity of the spraying edge, or arranged on the distribution surface.
- the profile of the distribution surface in a half-section passing through the axis of rotation of said rotary bowl has substantially the shape of an exponential.
- rapid growth we mean any function whose derivative increases with the variable.
- any rotary spray bowl combining a central supply (that is to say an axial injection of liquid, into 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 direct at least most of the liquid flow to said distribution surface.
- FIG. 1 is an axial sectional view of the spray bowl, according to arrow l-l of Figure 2;
- FIG. 2 is a view along arrow II of Figure 1;
- FIG. 3 is a section III-III of Figure 1;
- FIG. 4 is an enlarged view of Box IV of Figure 1.
- a liquid spraying device
- the element of revolution 12 essentially consists of an axial, tubular hub 13, extended forward by a divergent centrifugal deflector 14 having a circular spraying edge 15.
- the hub 13 constitutes or shelters a liquid supply conduit. The liquid to be sprayed propagates forward until it reaches a distribution surface 18, continuous, extending between the hub and the spraying edge.
- the hub 13 is intended to be mounted at the end of a hollow shaft of a drive device, not shown. Conventionally, 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 forward while 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 can be magnetic as described in document FR 2805182.
- Said distribution surface 18 is generally in the form of a trumpet horn and the liquid leaving the hub 13, more precisely here from the injector 17, is distributed in a thin film on the distribution surface progressing to the edge of spray where it is sprayed into fine droplets, under the effect of centrifugal force.
- the centrifugal deflector 14 is at least partially made of conductive material. electricity. 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 covered internally with an electrically conductive layer.
- the action of the high electric field, in the vicinity of the spraying edge 15, also contributes, like the effect of centrifugal force, to break the thin film into fine droplets.
- a continuous profile of the divergent centrifugal deflector such as that given by a trumpet shape, makes it possible, because of its large radius of curvature, to concentrate the electric field in the zone having the smallest radius of curvature, that is to say - say on the spray edge, precisely where the droplets are formed by an essentially mechanical effect.
- the trumpet shape is therefore favorable to all of 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 generally has the shape of a trumpet horn. In other words, said distribution surface generally has a certain convexity directed towards the object to be covered. Typically, the distribution surface in 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 shelters means for deviating substantially radially a part of the liquid towards the innermost part of the distribution surface 18.
- it is a distributor 22 mounted in the axial extension of the hub 13 and extending partly at the bottom of the deflector 14.
- This distributor has the function of deflecting the liquid introduced axially so that most of the liquid flow is directed towards the distribution surface 18 in the innermost zone thereof.
- This distributor 22 has a core 24 which obstructs the axial flow of the liquid. It is provided with radial passages 26 arranged at the rear of the core.
- the core 24 has a lateral surface of revolution 28 extending opposite and at a distance from the distribution surface 18, in the innermost zone thereof, to define with said surface an annular passage 30 extending said radial passages.
- the distributor 22 includes a tubular element of revolution 32, a rear mounting portion 34 of which is fixed inside the axial hub 13.
- the injector 17 ends with a nozzle engaged in the axial cavity of the mounting portion 34, facing the rear face of the core 24.
- the radial passages 26 are formed by three cutouts made in the element 32 between said mounting portion and the core 24. In fact, these three cutouts do not leave any residue in the element 32 that three bridges 36 offset circumferentially 120 degrees from each other and connecting said mounting portion 34 to the core 24.
- the most central part of the deflector is internally lined with an annular wear part 50 integrated into the innermost part of the distribution surface 18. More particularly, the apparent, internal surface of this annular part matches and extends the distribution surface 18 without breaking continuity. It is generally radially outside and facing the radial passages 26. This annular wear part can be fitted at the bottom of the deflector. In this case, it is intended to be replaced regularly.
- the annular part can on the contrary be made of a material very resistant to abrasion (ceramic, hard metal, etc.) or at least its internal surface, facing the radial passages 26, can be covered with a resistant material abrasion, for example titanium nitride.
- a resistant material abrasion for example titanium nitride.
- at least the innermost part of the distribution surface 18 is covered with a layer of abrasion-resistant material.
- the core 24 has 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 housing cylindrical, defined at the rear of the plug, 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 dispenser.
- the insert 46 is forcibly mounted in the insert 44.
- the channels 38 could be replaced by grooves made on the external surface of the insert 46 or on the internal surface of the housing of said insert. All these elements can be made of plastic or metal. The 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 deflected in part radially to the bottom of the distribution surface 18. The liquid continues to propagate, under the effect centrifugal force on this surface, forming a thin film which becomes thinner and thinner as it progresses towards the spraying edge. When the liquid reaches the spray edge, it is sprayed into fine droplets.
- a small part of the liquid engages in 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 forward and progresses radially towards the outside 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 a paint or varnish, there is therefore no risk of drying on the surface of the dispenser.
- the spray device can easily be cleaned by injecting a cleaning liquid in place of the liquid coating product.
- the ratio between the maximum diameter of the distributor 22 and the diameter of the spraying 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.
- the distributor 22 can be replaced by a radial wall attached to the element of revolution and comprising a ring of holes, this arrangement being known per se.
- 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 rotary drive device, such as for example a compressed air turbine, carrying the spraying device and arranged to allow an axial injection of liquid to be sprayed inside the hub.
- This sprayer is generally supplemented by a high voltage electrical supply bringing the centrifugal deflector 14 (conductor, for example metallic) to a high voltage.
- the rotation speed can be from 50,000 to 100,000 revolutions / minute and the device which has just been described is remarkable for its ability to give a very fine and very regular spraying (small difference in droplet size) , this in a very wide range of rotational speeds.
- the rotation speed can be lowered to 20,000 rpm with acceptable spraying. It may also be advantageous to provide means for supplying clean air inside the distributor 22 so that this air comes out through the annular passage 30 and / or the passage 40, in order to reduce the vacuum which forms in the center of the pavilion. and which could bring partially dried coating product droplets to the front of the distributor.
