Definitions

  • the present invention relates to atomization devices of the type in which the division of the fluid into fine droplets and the suspension of these in an air stream takes place inside the atomizer body and the mixing thus formed is expelled at high speed through an elongated opening formed in a nozzle with a hemispherical head so as to produce a flat jet of great width. These devices are used in particular for cooling continuous casting products.
  • the nozzle has a single slot producing a relatively thin jet.
  • the thickness of the jet can be increased by increasing the width of the slot, but the jet is then no longer homogeneous.
  • it is sought to obtain thicker and homogeneous jets over their entire section.
  • a nozzle for a sprinkler device comprising two slots arranged symmetrically with respect to a plane containing the axis of the nozzle and whose median planes are inclined relative to this plane of symmetry. These slots are arranged so as to produce two symmetrical jets watering two relatively narrow and diametrically opposite sectors. Such a nozzle does not produce a single homogeneous jet.
  • the object of the present invention is to provide a nozzle making it possible to obtain a wide, thick and homogeneous jet over its entire section.
  • the atomizing nozzle object of the invention comprises two slots arranged symmetrically with respect to a plane containing the axis of the nozzle and whose median planes are inclined relative to this plane of symmetry and is characterized in that the two slots are arranged so as to produce a common jet, in that the angle formed by the median plane of each slot with the plane of symmetry is between 5 ° and 40 ° and in that the two ends of the slots are located at the level from the base of the hemispherical head of the nozzle and away from said plane of symmetry.
  • the nozzles shown in the drawings are constituted by a part 10 in the shape of a glove finger comprising a hemispherical head 12 in which two slots are machined 14.
  • the part 10 At its base, the part 10 comprises an annular shoulder 16 allowing its fixing, by means of 'a nut, on the threaded end of the body of an atomizer. Lugs 18 ensure the correct positioning of the nozzle on the body of the atomizer.
  • the slots 14 are symmetrical with respect to a plane X-X containing the axis Y-Y of the nozzle. They have the shape of a semicircle and their ends are located approximately at the base of the hemispherical head 12 (plane Z.Z) and away from the plane of symmetry X-X.
  • the slots have parallel edges and their median planes are inclined at an angle a equal to about 20 ° relative to the plane of symmetry.
  • these slots In projection on a plane perpendicular to their median plane and to the plane of the figure (arrow F), these slots have an approximately trapezoidal shape, as shown in FIG. 3.
  • These slots are produced by milling using a saw mill or a cutter-three sizes on a universal milling machine with tilting head.
  • the slots which are arranged in the same way as on the nozzle of Figures 1 and 2 have a width which decreases from the ends towards the middle.
  • these slots In projection on a plane perpendicular to their median plane and to the plane of the figure (arrow F), these slots have the shape shown in FIG. 5, the longitudinal edges having in this representation a curved shape, for example in an arc of a circle.
  • the machining of these slots comprises two phases: first forming flat and parallel lip slots by milling, then giving the lips a curved shape by combination of an alternative cutting movement and a movement of advance circular.
  • these slots could be given a shape such that, shown as in FIG. 5, their longitudinal edges are constituted by broken lines with two segments (FIG. 6), three segments (FIG. 7) or more.
  • the slots are produced by milling, by means of a milling cutter, in two passes with rotation of the plane of the milling cutter between the two passes to produce the nozzle of FIG. 7, where the slots have a constant width in the area located halfway between the ends, a third pass is necessary to machine the middle part.
  • the inclination of the median plane of the slots relative to the plane of symmetry of the nozzle can vary from 5 ° to 40 °.
