Definitions

  • the invention relates to a device for feeding in blasting media via a feed line into the central area of the centrifugal wheel of a blasting system, wherein in the central area an allocation sleeve with an allocation opening is provided and an impeller with discharge openings rotates in the allocation sleeve, into which the blasting medium to be accelerated rotates occurs in the axial direction.
  • the object of the invention is now to reduce the wear of the blasting wheel caused by the blasting agent and at the same time to produce a blasting pattern with uniform coverage over the entire ejection angle of the blasting agent from the blasting wheel with an approximately parallel side boundary.
  • this object is achieved on the basis of a device for feeding in blasting media of the type described in the introduction in that the feed line for the blasting media opens into the impeller and has a trough-shaped tongue which projects into the impeller in the region of the feed opening.
  • the Impeller can be driven independently of the centrifugal wheel and at variable speed. It is also possible to provide a stirring element which is operatively connected to the drive shaft of the centrifugal wheel in the center of the impeller.
  • the inventive design of the mouth of the feed line with a channel-shaped tongue protruding into the impeller which essentially covers the area of the feed opening for the blasting medium into the centrifugal wheel, ensures that all particles of the blasting medium fed in are in a spiral orbit enter the impeller from the impeller.
  • the tongue protruding into the impeller is a barrier for the jet material emerging from the feed line on the direct path to the feed opening, so that the same cannot pass from the feed line to the feed opening directly, but only on a rotational path. This results in a smooth transition of the blasting medium into the blade area of the centrifugal wheel with subsequent uniform acceleration until the blade emerges and the impact of the blasting by means of the blades and side walls of the centrifugal wheel substantially prevented.
  • the smooth transition of the blasting medium from the impeller acting as a central accelerator into the centrifugal wheel ensures uniform guidance of the blasting medium in the centrifugal wheel, which not only achieves an even distribution of the blasting medium on the surface to be treated, but also wear on the centrifugal wheel and the effort required to accelerate the blasting medium Energy can be reduced.
  • FIG. 1 shows a schematic sectional view through a centrifugal wheel.
  • the centrifugal wheel 1 shown is of a housing
  • the drive shaft projects opposite the mouth of the feed line 3 4 of the centrifugal wheel 1 out of the housing 2.
  • the centrifugal wheel 1 has a side disk 5 which is fastened to the drive shaft 4 and carries blades 6 on the surface opposite the drive shaft 4, the inner ends of which are connected to an allotment sleeve
  • An impeller 9 or central accelerator which is connected in a rotationally fixed manner to the drive shaft 4 or the side window 5 and in which discharge openings 11 are formed, is provided within the allocation sleeve 7.
  • the blasting agent emerging from the feed line 3 passes through a trough-shaped tongue 10 which extends the area above the feed opening

Abstract

L'invention concerne un dispositif pour acheminer un agent de sablage par l'intermédiaire d'une conduite d'alimentation (3) dans la zone centrale de la roue centrifuge (1) d'une installation de sablage. Une douille de dosage (7) comportant une ouverture de dosage (8) est prévue dans la zone centrale. Dans cette douille de dosage (7), un rotor (9) comportant des ouvertures de décharge (11) tourne avec la roue centrifugeuse (1), l'agent de sablage à accélérer pénétrant dans ce rotor dans le sens axial. La conduite d'alimentation (3) pour l'agent de sablage débouche dans le rotor et présente une languette annulaire (10) qui fait saillie au niveau de l'ouverture de dosage (8) dans le rotor (9).
