Definitions

  • the innovation relates to a rotary atomizer according to the preamble of claim 1.
  • the innovation is based on the task of creating a rotary atomizer with condensation protection which requires as little energy and construction expenditure as possible.
  • the cover can lie against the atomizer housing in a forward-sealing manner and essentially form an air chamber around the outlet openings for the turbine exhaust air.
  • the continuously flowing exhaust air creates a slight excess pressure and thus a uniform air cushion around the essential part of the atomizer housing.
  • the air cushion prevents the warm and humid cabin air from coming into direct contact with the atomizer housing, which has cooled down to around 0 to + 3 ° C, for example.
  • the air permeability of the cover also prevents condensation on the cover itself.
  • the spray bell 1 of the atomizer is driven at high speed by an air turbine (not shown) located in the cylindrical housing 2.
  • an air turbine (not shown) located in the cylindrical housing 2.
  • the housing part 2 ⁇ on the side facing the spray bell 1 of the turbine housing there are bearings for the hollow shaft of the spray bell.
  • the compressed air supply line 3 for the turbine and an exhaust air cap 4 on the side of which facing the housing 2 the relaxed air coming from the turbine escapes into the environment (line 3 and the Cap 4 are arranged one behind the other perpendicular to the plane of the drawing).
  • the cover should be three-dimensional, i.e. be permeable to air throughout. It can expediently consist of a sufficiently porous, for example foamed plastic with good hydrophobic, ie water-repellent properties. Suitable plastics with, for example, 40 - 50% total pore volume are commercially available (e.g. under the trademark "Filtroplast").
  • a one-piece extension of the cover or a separate three-dimensional, air-permeable part which is fastened to a tubular body arranged similar to the cover 5 and can form the outer surface, can grip around the (left) edge of the turbine housing 2 and at least an essential one Also cover part of the end face 6 facing the spray bell 1.
  • a separate cover part made of insulating material (which possibly extends around the edge of the turbine housing and forms a front end face) can also be placed on the porous cover 5, which does not have to be porous with sufficient thermal insulation from the turbine housing 2.
  • a free air gap which essentially surrounds the entire housing and into which a line for blowing air opens into this ring-like gap.
  • the cover can be supported on the housing at the lateral edges of the gap.
  • the porous cover can be inserted between the turbine housing and an outer housing made of insulating plastic such as PTFE.
