Definitions

  • the invention relates to a centrifugal jet head according to the preamble of claim 1.
  • Centrifugal jet heads with the features of the preamble of claim 1 are already known, which have the shape of a box to be placed on the surface to be blasted, open to the surface to be blasted, the edge part of which is to be placed on the surface to be blasted is designed as a brush seal.
  • the blasting nozzle opens approximately vertically into the blasting chamber from above, and also at the upper end of the blasting chamber, that is to say approximately opposite the surface to be blasted facing blast chamber opening, an outlet nozzle for suction of the conveying air and the used blasting medium is arranged obliquely. It is known to form the lower wall section of the blasting chamber from transparent material in order to allow an insight into the blasting chamber.
  • the invention is based on the object of providing a centrifugal jet head which is easier and more convenient to use than the known centrifugal jet heads, which gives better radiation results and enables better observation of the radiation result.
  • the obliquely arranged blasting nozzle produces a better blasting result than the blasting nozzles of conventional centrifugal jet heads, which are directed essentially perpendicular to the surface to be blasted, and in connection with the outlet nozzle opposite, much better flow conditions are obtained in the blasting chamber, since the jet exits the blasting nozzle obliquely onto the surface to be blasted, is reflected on this and then, without hindering or impairing the incoming jet, reaches the outlet nozzle directly.
  • conventional centrifugal jet heads develop a countercurrent of the supplied jet and the exhaust air jet, which can have a considerable impact on the radiation effect.
  • the viewing window directly opposite the blasting chamber opening and thus expediently of approximately the same area enables direct and convenient observation of the blasting process without being obstructed by the exhaust air flow during
  • the spent blasting medium that has just been whirled up in the edge zones of the blasting chamber there is hardly any usable observation option, especially since there the transparent chamber wall is oriented perpendicular to the surface to be blasted.
  • the interchangeable arrangement of the viewing window according to claim 8 is advantageous because then the viewing window pane, if it has been scratched by the blasting agent, can be quickly replaced.
  • the sealing pad according to claim 9 on the edge part of the blasting chamber enables a reliable sealing of the blasting chamber to the surface to be blasted, even if this should be somewhat curved, and enables the blasting chamber to be moved easily on the object surface without damaging it.
  • the inlet check valve according to claim 10 allows the entry of outside air when a vacuum occurs in the blasting chamber when the work is interrupted, for example when the jet is briefly interrupted for better observability of the blasted surface through the viewing window.
  • the tapering flat trapezoidal box shape of the blasting chamber according to claim 7 results in optimal flow conditions.
  • the centrifugal blasting head has a blasting chamber 1 in the form of a relatively flat box, which has an opening 2 on its underside and an exchangeably mounted viewing window 3 on its opposite side.
  • the viewing window can be mounted in the blasting chamber by means of retaining strips 9 which can be screwed onto the chamber wall, these simple details not being shown in detail for the sake of clarity.
  • the edge part 1a of the blasting chamber 1 which surrounds the opening 2 of the blasting chamber carries a soft-elastic sealing pad 4 for placing the blasting chamber on the surface to be blasted.
  • a blasting nozzle 5 is arranged on the blasting chamber, the nozzle axis of which is oriented obliquely to the main plane of the opening 2.
  • an outlet connection 6 On the opposite side of the blasting chamber 1 with respect to the opening 2 of the blasting nozzle 5 there is an outlet connection 6, the axis of which is also oriented obliquely to the main plane of the opening 2, namely at approximately the same angle as the blasting nozzle 5.
  • the jet nozzle 5 is shown in Fig. 3 in more detail, although still very schematically. It is held on the wall of the blasting chamber 1 by means of an articulated flange stop 7, the articulated flange bearing allowing the jet nozzle 5 to be pivoted on all sides in the swivel angle range specified, for example. At the same time, the nozzle is guided so as to be longitudinally displaceable along its longitudinal axis and is biased into its rear position by means of a compression spring 8.
  • the longitudinal displaceability of the jet nozzle 5 is indicated in the drawings by the arrow x.
  • the jet nozzle 5 is not quite in its rearmost position in FIG. 3 in order to show a stop ring 5a at the front end of the nozzle more clearly, which limits the displaceability of the jet nozzle to the rear by a stop on the articulated flange bearing.
  • An inlet check valve 10 in the blasting chamber wall (FIG. 1) allows outside air to enter at a negative pressure in the blasting chamber.
