Definitions

  • the invention relates to a device according to the preamble of the first Claim.
  • the device for spraying on road markings intended.
  • the viscosity of the sprayed paints is very temperature-dependent and the manufacture of the colors measured and adjusted accordingly.
  • the Road marking is however in a widely varying temperature range applied from 2 to over 30 ° C.
  • the temperature fluctuation in a day can be more than 15 ° C.
  • the viscosity of the paint must therefore Application location also set by adding solvents be, which is very expensive because the entire amount of color must be post-processed, the amount supplied depending on the temperature fluctuation can be up to 4% with multiple settings are necessary daily.
  • Multi-component sprayers are known per se, but have These all have the disadvantage that the individual components only come out at the outlet of the Device come together.
  • Such an embodiment is e.g. in US-A-4, 927,079 (Binks), which is believed to be for applying a color in a color booth is suitable, in which there is a constant temperature.
  • the object of the invention is therefore to provide a device for spraying a multi-component color that matches each Temperature fluctuation is immediately adjustable, and at which the setting in the Device happens in there.
  • Fig. 1 shows a housing 1 with a connection 2 for compressed air, a Connection 3 for a first component A and a connection 4 for a second component B.
  • the connection 3 of the housing 1 flows Component A into a cylindrical prechamber 8 through a bore 11 in a cylindrical body 18.
  • a closing needle 5 with a valve 28 causes component A to be closed by a smaller bore 11a of the body no further to one end 18b of the body 18 can flow.
  • the compressed air reaches an upper one through connection 2 circular cylindrical annular space 17a of an annular body 17.
  • By radial Bores 17b and axial bores 17c get the compressed air into a first one Mixing chamber 24.
  • Component B reaches one through port 4 lower circular cylindrical annular space 17d of the annular body 17.
  • the axial bores 17c are each with the radial bores 17e aligned to the component B by means of compressed air in the mixing chamber 24 to atomize. All holes 17b, 17c and 17e are in the ring body 17 on Scope arranged at regular intervals, so as possible to achieve good mixing of compressed air / component B in the mixing chamber 24 is.
  • the mixing chamber 24 is on the one hand by a truncated cone Outer surface 18a of the cylindrical body 18 and a truncated cone upper inner surface 14a of an annular body 14 limited.
  • the lower part 18b of the body 18 extends to the end of the bore 14c of the ring body 14, The body 18 and the ring body 14 form a gap 11b, which the inflow the mixture of compressed air and component B to the mixing chamber 7 allows.
  • the lower inner surface of the ring body 14 is frustoconical formed so that a mixing chamber 7 together with the nozzle ring 10 arises.
  • Component A is inserted through the lower bore 18a of the body the mixing chamber 7 transported where it mixes with the compressed air and Component B mixed.
  • the mixing chamber 7 is on the one hand by the frustoconical inner surface 14b of the ring body 14 and the upper, inner, frustoconical surface 10a of the ring nozzle 10 formed with a milled slot 6 is provided.
  • Compressed air, component B and needle 5 are controlled jointly by actuating means
  • the nozzle ring 10 is closed by means of a ring nut 9, which with Internal thread 12 is provided, which in the external thread 13 on the housing 1st intervenes.
  • the mixing chamber 7 is the nozzle ring 10 and one Annular body 14 bounded against the inner wall 15 of the housing 1st abuts and inwardly extending along the inner wall 15 Has groove 16.
  • an O-ring 22 for sealing serves and the flange 19 is by means of an O-ring 23 against the projection 20th sealed.
  • FIG. 2 shows an embodiment which is different from that of FIG. 1 differs in that another component, namely C, is added.
  • the connection for C is on the same side as A and the Compressed air arranged.
  • the connection 4 for component B is located on the other hand, on the diametrically opposite side. In the way it is possible, connection for more than three components plus compressed air in the Install spray gun.
  • Annular body 25 are introduced with an annular space 25a and radial Bores 25b is provided.
  • the ring body 25 is fixed to the ring body 17 by bolts 27 such that the radial bores 25b are located below the axial bores 17c
  • Spray paint can be connected as component A to connection 3, while port 4 used for component B for the thinner is used for two-component paints for the catalyst becomes.
  • the connection 26 for component C can be used for other additives be used.
  • the spray liquid the current state of the surface to be sprayed, that is, one Road markings primarily to adapt to the temperature.
  • Another one The requirement is a short drying time and as gentle as possible Treatment of the environment.
