  • FR-A-1363681 proposes to use two or more ridge spraying devices.
  • a technical problem posed by the "multi-bowls" spraying means is the cleaning of the external surface of the internal bowls or bowls, soiled during the spraying where the rotation of the member creates a depression between the bowls which causes the deposition of droplets on an outer surface. This surface is difficult to reach by the solvent during rinsing.
  • FR-A-2 170 940 discloses a spraying member for spraying two separate products with two separate feed means. Such supply means, however, do not allow to simultaneously feed the two distribution surfaces of the spray member. In addition, the construction of such a spraying member is relatively complex and detrimental to the balance and compactness of this organ.
  • US-A-5,894,993 discloses a spray member comprising a single internal coating material distribution surface and an annular guide for guiding solvent to clean the outer surface of the spray member.
  • the flow of coating material sprayed by such a spraying member is relatively limited because there is only one spray edge.
  • the invention intends to remedy more particularly by providing a compact and compact multi-bowl spraying device whose geometry is such that the cleaning of the external surface of its internal bowl is facilitated.

  • the volume defined between the inner surface of the outer bowl and the outer surface of the inner bowl has a passage section which narrows in the direction of progression of the cleaning product towards the spraying edge of the bowl. external. Indeed, its thickness, which corresponds to the distance, taken perpendicularly to a median of this volume, between the inner surface of the outer bowl and the outer surface of the inner bowl, allows to control the distribution of the cleaning product in this volume.
  • the speed of the product increases between the bowls at the same time as the diameter of the bowls.
  • the pressure of the product between the bowls tends to decrease as the diameter of the bowls increases, i.e. in the direction of flow of the product.
  • the passage section is to be reduced, which provides the invention.
  • the passage section is to be reduced, which provides the invention.
  • the cleaning of these internal and external surfaces is thus optimized.
  • the central supply means can simultaneously feed the two internal distribution surfaces with a compact and balanced construction of the spray member

  • a body 2 fixed with respect to the axis X 1 -X ' 1 , surrounds the rotor 1 and is itself isolated from the outside by a cover 3.
  • An annular support 4 made of magnetic material, for example stainless steel magnetic, is mounted on the front face 21 of the body 2, this support being provided with an annular groove centered on the axis X 1 -X ' 1 and in which is disposed an annular magnet 41.
  • An injector 5 coating product is aligned on the axis X 1 -X ' 1 .

  • the insert 8 may not protrude from the surface 206.
  • the three forms of the insert 8 contemplated above make it possible to influence the distribution of the product between the flow paths formed by the surfaces 102 and 202 of the two bowls. Different types of bowls can therefore be provided, with inserts 8 of different geometry.
  • edges 101 and 201 are not in the same plane, they are offset axially with respect to each other, the edge 101 being set back relative to the edge 201, in order to avoid as much as possible jets of pulverized product recombine, that is to say, mingle with each other.
  • indented is meant that the edge 101 is further away from the objects O than the edge 201. It is necessary to separate as much as possible the jets of coating product from the edges 101 and 201. Indeed, if the These jets recombine, so the size of the droplets increases, while a uniform spray requires droplets as fine as possible.
  • the distance d 1 of withdrawal of the edge 101 with respect to the edge 201 may be 10 millimeters for a bowl whose edge 201 has a diameter of the order of 65 mm.
  • the distance d 1 represents more than 1% of the diameter D 201 of the edge 201, which ensures a good separation of the product jets without axially lengthening the bowl too much. The greater the shrinkage, the less jets of sprayed product recombine.

  • the air and solvent trains follow the same paths as the coating product, from the injector 5 to the edges 101 and 201.
  • the reduction of the gap between the bowls 100 and 200 of e 1 to e 2 has the effect of compensating for a decrease in pressure due to the centrifugal force and of slightly compressing the rinsing liquid to allow the force-feeding of the volume V 1 during rinsing of the spray member, thereby rinsing the surface 102 and the surface 203 at the same time.
  • the injection of cleaning product can properly clean not only the inner surfaces 102 and 202, but also the surface 203.
