Definitions

  • the invention relates to a powder flame spraying device consisting of a device base body, on which a flame spray nozzle with a special accelerator nozzle is arranged on its front side, which is fed by the device base body with accelerator gas, for which purpose blow-out openings are provided on the device base body, which are provided in an annular gap between the flame spray nozzle and a removable one Union sleeve open.
  • a powder flame spraying device has therefore already been built in which two special nozzle tubes are attached to a clamping ring on the flame spraying nozzle. These tubes are then further away from the flame spray nozzle and its flame and can then be aligned at the flame tip or in front of it at any point where the required kinetic energy can be given to the material that has already melted. These tubes are fed separately from a special distributor piece on the basic device body through special hose feeds for the accelerator gas. This device is cumbersome because the clamping ring with the tubes and the distributor with the hose connections have to be mounted separately on the powder flame spraying device. In addition, the alignment of the tubes must be carried out separately so that they blow the accelerator gas into the correct position with respect to the flame in front of the flame spray nozzle. In addition, the separate feed hoses, the distributor and the clamping ring with the protruding nozzle tubes hinder the proper operation of the powder flame spraying device by the operator during operation.
  • the cross section shown in this figure relates to an embodiment in which the coupling sleeve 25 and the fitting sleeve 31 are designed to be cylindrical to match one another.
  • the cross section is through the central transport gas line 3, as is obvious.
  • FIG. 2 shows a special development of the powder flame spraying device, only the front part of the adapter sleeve 31 with the flame spray nozzle 2 being shown for the sake of simplicity.
  • the components which correspond to the embodiment according to FIG. 1 have the same reference numerals and are not further explained here.
  • the adapter sleeve 31 is shown in a position rotated by 90 angular degrees with respect to the longitudinal axis 38 relative to FIG. 1.
  • two diametrically opposite cooling nozzles 34 are provided, which on the one hand open into the annular space 30 supplied with compressed air and on the other hand protrude forward over the end face 39.
  • the nozzle tubes 20 are angled to the longitudinal axis 38, while the cooling nozzles 34 are straight and project with their front ends of the nozzle tube 20 at a predetermined distance 40.
  • the two angled nozzle tubes 20 which have already been explained are effective according to the invention as accelerator nozzles.
  • Special nozzles for example ball-bearing nozzles, which allow the direction of exit of the cooling medium to be controlled as desired, may also be used at the outlet opening 35.
