Definitions
- the invention relates to a centrifugal wheel with radially standing blades which are fastened to at least one side disk and the inner ends of which are at a distance from the center, and with an impeller cage with discharge openings arranged in the central region thereof, which rotates together with the centrifugal wheel and in the central area the blasting medium to be accelerated is fed in the axial direction.
- an impeller cage with discharge openings arranged in the central region thereof which rotates together with the centrifugal wheel and in the central area the blasting medium to be accelerated is fed in the axial direction.
- the object of the invention is now that of the to reduce medium-related wear of the centrifugal wheel and at the same time to generate a jet pattern with uniform coverage over the entire ejection angle of the steel means from the centrifugal wheel with an approximately parallel side boundary.
- the blasting medium fed in moves on a circular path even before it enters the centrifugal wheel, so that the blasting medium Part, which leaves the auxiliary centrifugal wheel, enters the centrifugal wheel in a spiral orbit, whereby the impact of the blasting agent on the blades of the centrifugal wheel is substantially prevented.
- the guide vanes continue to collect and channel the stray blasting agent, thereby achieving a uniform distribution of the blasting agent on the surface to be treated.
- the blades of the auxiliary centrifugal wheel are tapered in the direction of its feed end, so that when this centrifugal wheel rotates they form a conically narrowing cavity in the direction of flow of the blasting medium, via which the blasting medium optimally increases the throughput in the blade region of the auxiliary centrifugal wheel can penetrate. It has also proven itself to be effective on the free ends of the blades of the auxiliary centrifugal to arrange a frustoconical sleeve widening in the flow direction of the blasting medium. This sleeve can also be formed by a corresponding funnel-shaped widening of the outlet end of the feed pipe for the blasting agent to form a blasting system.
- ribs are provided on the outer surface (s) of the side plate (s) of the centrifugal wheel.
- the centrifugal wheel can be designed as a welded construction with straight or curved blades, which leads to a considerable reduction in weight.
- Fig. 1 a schematic sectional view through an inventive centrifugal wheel, which is arranged in a housing.
- the centrifugal wheel 1 shown is of a housing
- the centrifugal wheel 1 has a side disk 5 which is fastened to the drive shaft 4 and on the surface opposite the drive shaft 4. fine 6 carries, the inner ends of which adjoin an allotment sleeve 7 with an allotment opening 8. Between the blades 6, guide blades 9 are still held on the side window 5, the inner ends of which, in contrast to the inner ends of the blades 6, are at a distance from the allocation sleeve 7.
- the free ends of the blades 11 of the auxiliary centrifugal wheel 10 taper arrow-like in the direction of the feed end for the blasting agent or the feed pipe 3, so that in the interior of the rotating auxiliary centrifugal wheel 10 a conical or cup-shaped cavity 12 in the direction of the side window 5 arises through which the blasting agent enters the auxiliary centrifugal wheel 10.
- the tapered free ends of the blades 11 of the auxiliary centrifugal wheel 10 protrude into the funnel-shaped expansion of the blade shape.
- Ribs 14 are also formed on the surface of the side window 5 opposite the blades 6.
- the invention is not limited to the illustrated and described embodiment. It includes modifications familiar to those skilled in the art.
- more than one guide blade 9 can also be provided on the centrifugal wheel between the individual blades 6.
- the guide blades 9 can have the same radial length as the blades 6 and consequently protrude beyond the outer ends of the blades 6.
