Definitions

  • the invention relates to a Vollkegelsprühdüse, in particular for spraying low-viscosity liquids for cooling in billet or Vorblockstranggussanlagen, with a mouthpiece, with an outlet chamber and an outgoing from the outlet chamber outlet opening with a smaller cross-section than the outlet chamber.
  • a mouthpiece of this nozzle has an outlet chamber with an outlet opening extending from the outlet chamber with a smaller cross section than the outlet chamber.
  • a swirl insert is arranged, with which the gas-liquid mixture is rotated before reaching the outlet opening in rotation, so that it can then emerge conically under pressure from the mouthpiece.
  • the swirl insert has several holes or circumferentially arranged millings on, which are evenly distributed over the circumference.
  • a mixing chamber is provided upstream of the swirl insert and optionally separated by an extension tube from the mouthpiece in which a gas flow and a liquid flow are perpendicular to each other and thereby mixed. Due to the pronounced rotation of the gas-liquid mixture before reaching the outlet opening, other than circular spray cone shapes can not be satisfactorily molded.
  • a slot nozzle is provided for cooling in continuous casting plants.
  • an oval spray cone shape is to be achieved.
  • a mouthpiece has an outlet chamber with an outlet opening, which has a smaller cross section than the outlet chamber, wherein the outlet opening has an oval cross section.
  • a transverse web is arranged in the outlet chamber, which leaves free on both sides only in each case a circular segment-shaped inlet opening, which are arranged symmetrically to the center of the outlet chamber.
  • the wall of the outlet chamber is formed in the region of the outlet opening so that the liquid streams meet at or immediately before the outlet opening, in a range between 60 ° and 130 °.
  • a Vollkegelsprühdüse in particular for spraying low-viscosity liquids for cooling in billet or Vorblockstranggussanlagen be created in which a homogeneous liquid distribution is realized with low constipation sensitivity.
  • a Vollkegelsprühdüse in particular for spraying low-viscosity liquids for cooling in billets or Vorblockstranggussanlagen, provided with a mouthpiece having an outlet chamber and an outlet opening from the outlet chamber of smaller cross-section than the outlet chamber, wherein an inlet opening into the outlet chamber has a smaller cross-section than the outlet chamber and at the downstream of the inlet opening in the outlet chamber a web-like Vorzerstäuberelement is arranged, on which a fluid jet after entering the exit chamber at least partially impinges.
  • the web-like Vorzerstäuberelement on the one hand prevents the penetration of an incoming fluid flow to the outlet opening and on the other hand ensures a thorough rupture of the fluid jet. Since no pronounced rotation of the fluid jets occurs in the exit chamber, non-circular cross-sectional shapes of a full-jet jet with uniform distribution can be produced. This results in a uniform fluid distribution in the spray cone at a malleable cross-section of the spray cone, and at the same time large passage cross-sections are achieved in the spray nozzle, which ensure a low risk of clogging.
  • the fluid jet enters the outlet chamber parallel to a longitudinal axis of the nozzle and also the outlet opening lies in the longitudinal axis of the nozzle.
  • a sudden cross-sectional widening of a flow channel is provided at the transition of the inlet opening into the outlet chamber.
  • the inlet opening is provided in a diaphragm and has a radius of 2.5 mm.
  • the outlet chamber may then have, for example, a radius of about 6 mm, whereby even with a smaller cross-sectional widening, for example only to twice, a sufficient effect can occur.
  • a determination of the output fluid volume flow takes place by means of the cross section of the inlet opening.
  • the inlet opening is provided within a diaphragm, so that a different fluid volume flow can be realized by replacing the diaphragm.
  • the spray cone is shaped by means of the outlet opening and optionally by means of an outlet cone adjoining the outlet opening.
  • the exit cone or exit truncated cone in the mouthpiece housing can have an arbitrarily shaped, deviating from the circular shape cross-sectional shape. Since in the nozzle according to the invention, the rupture and atomization of an incoming fluid jet in the pre-atomizer and the outlet chamber, the shape of the outlet opening can be changed without a liquid distribution within the spray cone to change fundamentally by changing the shape of the outlet opening.
  • the outlet opening has an oval cross-sectional shape and, advantageously, an expanding outlet cone with an oval cross-section adjoins the outlet opening in the outlet direction.
  • an oval or oval shape is understood to mean an ellipse-like shape, but beyond that also an oval shape in the strict sense, that is to say two semicircles interconnected by straight lines.
  • the web-like Vorzerstäuberelement extends with its longitudinal direction substantially perpendicular to an incoming fluid jet through the outlet chamber, wherein the longitudinal direction relative to a longer axis of the oval outlet opening at an angle between 0 ° and 360 °, in particular 90 °, is arranged ,
  • the pre-atomizing element can be arranged in different angular positions relative to a longitudinal axis of the outlet opening.
  • an arrangement of the web-like pre-atomizing element has proven to be particularly advantageous at an angle of 90 ° to the longer axis of the oval outlet opening.

  • an exact distance between Vorzerstäuberelement and inlet opening can be ensured.
  • the Vorzerstäuberelement is designed as a web with rechteckartigem cross section, wherein a narrow side of the rectangle faces the inlet opening.
  • the narrow side of the rectangle thereby forms an impact surface for at least part of the fluid jet entering through the inlet opening. If the narrow side is narrower than the inlet opening, an incoming fluid jet is divided into three partial streams. A first partial flow impinges on the pre-atomizer element, two further partial flows pass through the pre-atomizer element on the right or left side.
  • the Vorzerstäuberelement can be as wide as the inlet opening, so that then no division into partial beams takes place but the entire incoming fluid jet impinges on the Vorzerstäuberelement.
  • the web-like pre-atomizing element is designed as a round rod extending transversely through the outlet chamber.
  • a round rod can be inserted and fixed by providing a simple bore in the mouthpiece housing in this.

Since the output fluid volume flow is determined by the inlet opening in the diaphragm, such an adaptation of the shape of the outlet opening does not lead to a change in the dispensed fluid volume flow. Conversely, the output fluid volume flow can be adjusted by changing the aperture without significantly changing the shape of the dispensed spray cone.
