Definitions

  • the invention relates to a shaping air ring for a nebulizer and a corresponding coating method according to the independent claims.
  • High-speed rotary atomizer which atomize the paint to be applied (for example, powder paint, wet paint) by means of a rapidly rotating bell cup, wherein the rotating bell cup emits a spray at a circular encircling Glockentellerkante, which widens in spray jet direction.
  • a directing air jet which is directed by a directing air ring from behind against the spray, so that the spray jet is constricted in dependence on the strength of the shaping air jet.
  • a disadvantage of the known high-speed rotary atomizers described above is the fact that the paint particles not deposited on the component to be coated ("over-spray") can foul far-reaching surfaces, such as, for example, the booth walls of a paint booth or handling equipment in the paint booth.
  • the known high-rotation atomizers can thus lead to contamination over long distances.
  • the invention is therefore based on the object to reduce the pollution prone room area in the known Rotationszerstäubern. This object is achieved by an inventive shaping air ring and a corresponding coating method according to the independent claims.
  • the invention is based on the technical-physical realization that frictional effects in the interior of the spray jet generate a negative pressure, which contributes to a concentration of the spray jet, so that the spray jet is stable over relatively large distances.
  • the friction on the outer surface of the spray is too small to cause a significant beam expansion of the spray.
  • the spray jet emitted by the rotary atomizer can have a large spatial length, while maintaining the internal flow rate, so that the applied coating agent particles can cause contamination even at a great distance from the rotary atomizer.
  • the invention therefore encompasses the general technical teaching of specifically generating turbulences in the shaping air jet and thus also in the spray jet in order to limit the undisturbed range of the spray jet and thus the spatial contamination potential.
  • turbulences in the spray jet are fundamentally undesirable and should therefore be limited to a remote area within the scope of the invention.
  • the spray jet or the surrounding directing air jet should preferably be directed and low in turbulence, so that the coating quality is not impaired by turbulence.
  • the spray jet thus has a significantly greater degree of turbulence in the far range than in the near range.
  • additional irregularities are provided in comparison to a conventional shaping air ring with a rotationally symmetrical arrangement of the shaping air nozzles, on the one hand the original function of the
  • the directing air jet has a decay length from the directing air ring to the turbulent far end, which is less than 1 m, 75 cm, 50 cm, 40 cm, 30 cm or 20 cm. This limits the spatial contamination potential of the nebulizer to the near area of the nebulizer, thus preventing the contamination of remote surfaces.
  • the decay length of the shaping air jet is preferably greater than the component distance between the shaping air ring and the component to be coated, so that the component to be coated is located in the directional and low-turbulence near region of the spray jet. This is advantageous because the component to be coated is then in the vicinity, so that the coating quality by the relatively strong turbulence in the long range is not affected.
  • the irregularities for generating the turbulence are that the shaping air nozzles are arranged asymmetrically with respect to the spray axis and the axis of rotation of the atomizer, respectively. not rotationally symmetric.
  • the nozzle cross-section and / or the jet direction of the individual shaping air nozzles can be varied over the circumference of the shaping air ring.
  • the flow velocity over the circumference of the shaping air ring faster and slower flows in the shaping air jet run side by side, which leads to velocity gradients and thereby flow friction in the spray jet, whereby turbulences are then produced in the course of the spray jet.
  • one part of the shaping air nozzles has a jet direction which is aligned substantially parallel to the spray axis of the atomizer, while another part of the shaping air nozzles has a jet direction which is inclined radially inward with respect to the spray axis.
  • the shaping air ring according to the invention can have six groups each with five shaping air nozzles, wherein three groups have shaping air nozzles which are aligned substantially axially parallel to the spray axis, while the other three groups comprise shaping air nozzles whose jet direction is inclined radially inwards with respect to the spray axis.
  • a part of the shaping air nozzles has a jet direction, which is inclined radially inwards with respect to the spray axis, while another part of the shaping air nozzles has a jet direction which is inclined radially outward with respect to the spray axis.
  • the individual shaping air nozzles are therefore inclined either radially inwards or radially outwards.
  • the individual shaping air nozzles are here also subdivided into groups with a uniform jet direction, wherein the different groups of the shaping air nozzles are arranged alternately in the circumferential direction.
  • a part of the shaping air nozzles is arranged on an inner ring, while another part of the shaping air nozzles is arranged on an outer ring.
  • the shaping air nozzles on the inner ring preferably have a jet direction which is inclined radially outward with respect to the spray axis, while the shaping air nozzles on the outer ring preferably have a jet direction which is inclined radially inwards relative to the spray axis.
  • the shaping air nozzles are preferably arranged in groups with a uniform beam direction, wherein the different groups are arranged alternately in the circumferential direction.
  • the shaping air jet has the shape of a flat jet.
  • two mutually opposite groups of shaping air nozzles each have a jet direction, which is inclined radially inwardly with respect to the spray axis, while two other, likewise mutually opposite groups of shaping air nozzles have a jet direction which is aligned substantially parallel to the axis of the spray axis or opposite the spray axis is inclined radially outward.
  • the radial Inwardly inclined shaping air nozzles thus compress the resulting shaping air jet into a flat jet.
  • the individual shaping air nozzles have a jet direction which is inclined radially inwards relative to the spray axis, which leads to a crossing shaping air flow and causes a constriction of the spray jet downstream of the bell cup. Behind the constriction, the
  • the turbulence-generating irregularities consist essentially of variations in the jet direction of the shaping air nozzles.
  • the irregularities for generating the desired turbulences can also consist of variations of the nozzle cross-section of the individual shaping air nozzles, which leads to corresponding variations in the flow velocity.
  • the nozzle cross section can be varied over the circumference of the shaping air ring, wherein the shaping air nozzles can again be subdivided into different groups with uniform cross sections.
  • the irregularities for generating the turbulence may consist in that the nozzle cross section of the shaping air nozzles widens conically or tapers in the direction of flow.
  • the turbulence generation irregularities can consist of slots which adjoin the shaping air nozzles and run essentially parallel to the flow direction.
  • the slot can likewise be arranged annularly on the shaping air nozzle ring and cut all shaping air nozzles.
  • the slots are arranged in a cross shape and concentric with the individual shaping air nozzles.
  • the turbulence generation irregularities may be that the flow profile of the shaping air nozzles is deliberately distorted.
