Definitions

  • the invention relates to a device for feeding of blasting media via an inlet pipe into the central area the trained as a paddle wheel to his Longitudinal axis of rotating and motor-driven centrifugal wheel a blasting machine, being in the central area an allotment sleeve with an allotment opening is provided and in the allotment sleeve together with the centrifugal wheel an auxiliary centrifugal wheel with a rotating body in the center is provided, rotates and into which the abrasive to be accelerated in the axial direction occurs, the length of the rotating body at least corresponds to the width of the auxiliary centrifugal wheel.
  • GB-A-1 552 679 becomes a portable beam device described in which the abrasive with a air or gas flow under pressure an inlet pipe fed into an impeller cage becomes.
  • An allotment opening is formed in the impeller cage, through which the abrasive from the impeller cage in the effective area of the blades of a centrifugal wheel entry.
  • the mouth of the inlet pipe is axial Direction directed to the feed opening, so that from the blasting agent blown with compressed air is a considerable one Part immediately enters the feed opening, d. H. before entering the allotment opening on none Circular path, but linear and transverse to the blade movement is transported.
  • GB 441 466 A there is also a beam device known in which the abrasive under the action gravity through an inlet pipe into an impeller is fed.
  • the outlet opening of the inlet pipe flows into the impeller and extends over it entire width or depth.
  • the impeller is one Allotment sleeve surrounded.
  • the allocation sleeve is adjustable around the axis of the Centrifugal wheel held to by adjusting the position the dispensing opening the direction of the of the beam device emitted or emerging from the centrifugal wheel accelerated abrasive the respective Adapt to needs.
  • the object of the invention is now that of the abrasive conditional wear of the centrifugal wheel reduce and at the same time a spray pattern with more uniform Coverage over the entire ejection angle of the Blasting media from the centrifugal wheel at approximately parallel Generate page boundary.
  • the auxiliary centrifugal wheel ensures that all fed particles of the abrasive on a spiral orbit from the auxiliary centrifugal wheel enter the centrifugal wheel because not immediately, but only on a rotation path from the feed opening to the feed opening can reach. This results in a soft takeover of the abrasive in the blade area with subsequent even acceleration until the blade exit and the impact will of the abrasive on the blades and Sidewalls of the centrifugal wheel essentially prevented.
  • ribs or auxiliary blades in the auxiliary centrifugal wheel which is towards its Feed side can taper, so that when Rotate the centrifugal wheel in the auxiliary centrifugal wheel one in the direction of flow of the abrasive form narrowing cavity over which the blasting agent to increase the throughput optimally in penetrate the effective area of the auxiliary centrifugal wheel can.
  • the centrifugal wheel shown in Figures 1 and 2 1 is surrounded by a housing 2 in which an inlet pipe 3 opens with which the blasting agent such as quartz sand or blasted shot to the centrifugal wheel 1 is supplied. Opposite the infeed side the drive shaft 4 projects for the abrasive the centrifugal wheel 1 out of the housing 2.
  • the centrifugal wheel 1 has a side window 5, which is attached to the drive shaft 4 and on the drive shaft 4 opposite Surface Scheufeln 6 carries, the inner ends of adjoin an allotment sleeve 7 with an allotment opening 8.
  • an allotment sleeve 7 Within the allotment sleeve 7 is a non-rotatable with the drive shaft 4 or the side window 5 connected auxiliary centrifugal wheel 9 or central accelerator trained in the center of it sleeve-shaped rotating body 11 is provided, which protrudes from the auxiliary centrifugal wheel 9.
  • auxiliary centrifugal wheel 9 are on the inner wall of the auxiliary centrifugal wheel 9 ribs 10 or auxiliary blades still arranged, towards the end of the feed for taper the blasting agent or the feed pipe 3, so that in the interior of the rotating auxiliary centrifugal wheel 9 one towards the side window 5 annular or sleeve-shaped cavity is created, through which the blasting agent in the auxiliary centrifugal wheel 9 occurs.
