Definitions
- the invention relates to a centrifugal wheel with radial standing blades on at least one side window are attached and their inner ends are spaced to the center, as well as with one in the central area arranged impeller cage, which rotates together with the centrifugal wheel and in it Central area the abrasive to be accelerated is fed in the axial direction.
- the object of the invention is now that of the abrasive to reduce conditional wear on the centrifugal wheel and at the same time a spray pattern with a uniform Covering over the entire ejection angle of the steel medium from the centrifugal wheel at approximately parallel Generate page boundary.
- centrifugal wheel of the type described above solved that between the blades of the centrifugal wheel Guide blades are arranged, the inner ends of which a greater distance from the center of the centrifugal wheel than those of the blades and the impeller cage is designed as an auxiliary centrifugal wheel, wherein the axial length of the blades of the auxiliary centrifugal wheel that of the blades of the centrifugal wheel considerably surpasses.
- the inventive design of the impeller cage the feed moves as an auxiliary centrifugal wheel Abrasives before entering the Centrifugal wheel on a circular path so that the abrasive, which leaves the auxiliary centrifugal wheel on a spiral orbit enters the centrifugal wheel, causing the blasting agent to impact the blades the centrifugal wheel essentially prevented becomes.
- the vagabundant abrasive and channel creating an even distribution of the abrasive on the surface to be treated is achieved.
- the blades of the auxiliary centrifugal wheel in the direction of its feed end tapers so that it rotates this centrifugal wheel one in the flow direction of the Blasting medium form conically narrowing cavity, through which the abrasive to increase the throughput optimal in the bucket area of the auxiliary centrifugal wheel can penetrate. It has also proven itself on the free ends of the blades of the auxiliary centrifugal wheel a widening in the direction of flow of the abrasive Arrange frustoconical sleeve. This sleeve can also be funnel-shaped Extension of the outlet end of the inlet pipe for the Blasting media to be formed to a blasting machine.
- ribs of the centrifugal wheel are provided on the outer surface (s) of the side window (s) ribs of the centrifugal wheel.
- centrifugal wheel can cause minor wear as a welded construction with straight or curved Blades are formed, which results in significant Losing weight leads.
- the centrifugal wheel 1 shown is of a housing 2 surround, in the central area an inlet pipe 3 opens with which the blasting medium such as quartz sand or Steel shot is fed to the centrifugal wheel 1. Across from The drive shaft protrudes from the mouth of the inlet pipe 3 4 of 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 surface of the drive shaft 4 opposite blades 6 carries, the inner ends of an allotment sleeve 7 adjoin with an allotment opening 8. Between Blades 6 are still guide blades on the side window 5 9 held, the inner ends in contrast a distance from the inner ends of the blades 6 have to the allocation sleeve 7.
- auxiliary centrifugal wheel 10 is formed inside the allotment sleeve 7 a non-rotatable with the drive shaft 4 or Side window 5 connected auxiliary centrifugal wheel 10 is formed. The axial length of the blades exceeds 11 of the auxiliary centrifugal wheel 10 that of the blades 6 and guide blades 9 of the centrifugal wheel 1 considerably.
- the free ends of the blades 11 of the auxiliary centrifugal wheel 10 taper towards that End of feed for the abrasive or the feed pipe 3 arrow-like, so that in the interior of the rotating auxiliary centrifugal wheel 10 one towards the side window 5 conical or cup-shaped cavity 12 is formed, through which the abrasive in the auxiliary centrifugal wheel 10 occurs.
- the tapered free ends of the Paddles 11 of the auxiliary centrifugal wheel 10 protrude into that the funnel-shaped widening adapted to the shape of the blade End 13 of the inlet pipe 3.
- the invention is not limited to that shown and described Embodiment limited. So can on the centrifugal wheel between the individual blades 6 more than one guide blade 9 is also provided be.
- the guide blades 9 can have the same radial length how the blades 6 have and thus protrude beyond the outer ends of the blades 6.
