Definitions

  • the invention relates to a device for feeding blasting agent via a supply line into the central region of the blast wheel of a blasting system, wherein in the central region an allotment sleeve is provided with a metering opening and in the metering sleeve together with the impeller rotates an impeller with discharge openings, in which the blasting agent to be accelerated enters in the axial direction.
  • the object of the invention is therefore to reduce the abrasion caused by the blasting agent of the impeller and at the same time to produce a spray pattern with uniform coverage over the entire ejection angle of the blasting medium from the blast wheel with approximately parallel side boundary.
  • This object is achieved on the basis of a device for feeding blasting agent of the type described above in that the feed line for the blasting agent opens into the impeller and has a channel-shaped tongue which protrudes in the region of the metering opening in the impeller. It can the Impeller independent of the impeller and driven at variable speed. It is also possible to provide in the center of the impeller an operative with the drive shaft of the impeller stirring member.
  • the bumpless transition of the blasting agent acting as a central accelerator impeller in the impeller ensures uniform guidance of the blasting agent in the impeller, which not only achieves a uniform distribution of the blasting agent on the surface to be treated, but also the wear on the impeller and expended on the acceleration of the blasting agent Energy can be reduced.
  • the illustrated impeller 1 is surrounded by a housing 2, in whose central region a supply line 3 opens, with which the blasting agent such as quartz sand or steel shot is fed to the impeller 1. Opposite the mouth of the supply line 3 protrudes the drive shaft 4 of the blast wheel 1 out of the housing 2 out.
  • the blast wheel 1 has a side plate 5, which is fixed to the drive shaft 4 and on the opposite side of the drive shaft 4 carries blades 6, the inner ends of which adjoin an allocation sleeve 7 with a metering opening 8.
  • a metering sleeve 7 Within the metering sleeve 7 is a non-rotatably connected to the drive shaft 4 and the side plate 5 impeller 9 or.
  • Central accelerator provided in the discharge openings 11 are formed.
  • the blasting agent emerging from the feed line 3 passes into the impeller 9 via a groove-shaped tongue 10, which essentially covers the area above the metering opening 8 in the metering sleeve 7.
