Definitions
- the invention relates. a blower for a blasting machine, the formed Elrad rotatable about its longitudinal axis, and as mot'orisch ant'reibbar Schauf 'is as well as in its Zent'ral Geneva a Zut express sleeve with' a Zut 'f eilöf voltage has. , in the ingredient sleeve together with! the centrifugal wheel an auxiliary centrifugal wheel rotates, into which the steel to be accelerated is fed in the axial direction.
- the object of the invention is? it is now to reduce the wear of the centrifugal wheel caused by the steel and, at the same time, a steel picture with? to produce uniform Elndeckung gethese'en over the ejection angle of the St 'rahlmit'tels from the centrifugal wheel in approximately parallel Seit'enbegrenzung.
- the arrangement according to the invention of the feed opening for the steel medium and the design of the auxiliary centrifugal wheel ensure that all the particles of the blasting medium which are fed in enter the centrifugal wheel in a spiral orbit from the auxiliary centrifugal wheel, since they do not directly, but only on a rot'at'ion path from the feed opening to the component opening. This results in a soft transfer of the St'rahlmit't'els into the bucket area with subsequent even acceleration until the bucket is ' rit? T 'and the impact of the St'rahlmit't ' els on the blades and side walls of the Centrifugal wheel essentially prevented.
- the smooth transition of the steel medium from the auxiliary centrifugal wheel acting as a central accelerator into the centrifugal wheel ensures a uniform guidance of the steel ram in the centrifugal wheel, so that? only an even distribution of the steel rod on the surface to be treated is achieved, but also the wear on the centrifugal wheel and the energy required to accelerate the steel rod are reduced: are reduced.
- Fig. 1 a schematic sectional view? through a centrifugal wheel that is arranged in a housing? is'.
- Fig. 2 is a schematic Schnit 't'ansicht by the impeller and the housing along the line II of Fig. 1.
- the impeller 1 shown in Figures 1 and 2 ' is surrounded by a housing 2 in which an inlet pipe 3 opens' is supplied to the spinner 1 'where the St' 'rahlschrot' rahlmitt'el such as quartz sand or St? becomes. Is it opposite the feed side for the St'rahlmitt ' el? the drive shaft 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? is 'and on the surface opposite the drive shaft 4 Scheufein 6 t'?, whose inner ends a Zut 'adjacent eilhülse 7 with a Zut'eilö réelle. 8 Within the allot 'eilhülse 7 is? a rotatable 'with? the auxiliary shaft 9 or central accelerator connected to the drive shaft 4 or the side plate 5, in the center of which a sleeve-shaped rotating body 11 is provided which protrudes from the auxiliary wheel 9.
- the side of the rotary body 11 opens in the rotational direction of the impeller 1 according to the Zut 'eilötechnisch 8, the feed pipe 3 in the Hilfsschleuderrad 9 so that the light emerging from the inlet pipe 3 St'rahlmitt'el outside the center in the Hilfsschleuderrad 9 is fed.
- auxiliary centrifugal wheel 9 On the inner wall of the auxiliary centrifugal wheel 9 ribs 10 or auxiliary blades are arranged, which taper in the direction of the end of the feed for the blasting agent or the feed pipe 3, so that in the interior of the rotating auxiliary centrifugal wheel 9 a ring or sleeve-shaped in the direction of the side window 5 Cavity is created through which the blasting media enters the auxiliary centrifugal wheel 9 occurs.
