Definitions

  • the invention relates to an impeller for feeding of blasting agent to be accelerated in the blast wheel of a blasting system, wherein the impeller in the central region of the impeller within a metering sleeve having a metering opening, and is rotatable in the direction of rotation of the impeller and wherein the impeller trimmed on the metering sleeve ,
  • tabular, guide elements for guiding the blasting agent to the outside which are arranged on at least one side window.
  • the object of the invention is to reduce the abrasion caused by the blasting agent of the impeller and at the same time to produce a spray pattern with uniform coverage over the entire ejection angle of the blasting agent from the blast wheel at approximately parallel side boundary.
  • the recess or the cavity can be formed directly by the legs.
  • legs of the profile piece on the one hand point in the direction of the metering sleeve, they expediently show on the other hand at least approximately in the direction of the axis of rotation of the impeller.
  • the two legs of the profile piece preferably extend at an angle to each other, in particular at least approximately V-shaped or the two legs form a V-shape.
  • at least one leg, preferably both legs of the profile piece extend at an angle to the radial direction of the impeller, in particular the side window.
  • the legs of the profile pieces can be connected to each other in a further embodiment by a preferably extending at an angle to the legs web.
  • the web can run, for example, straight or curved. It is also possible, the legs of the profile pieces of different lengths form. It has also proven useful to provide between the legs of the profile pieces in the direction of the dispensing sleeve extending, preferably tabular transport elements.
  • the blasting agent passes through the discharge channels with channel end discharge openings from the rotating impeller into the spaces between Zuteilhülse and impeller on a nearly circular path. Subsequently, the blasting medium circulates in this area between the metering sleeve and the impeller along this circular path.
  • the blasting agent passes through the discharge channels with channel end discharge openings from the rotating impeller into the spaces between Zuteilhülse and impeller on a nearly circular path.
  • the blasting medium circulates in this area between the metering sleeve and the impeller along this circular path.
  • the bumpless transition of the blasting medium acting as a central accelerator impeller in the impeller causes a uniform guidance of the blasting agent in the impeller, whereby not only a uniform distribution of the blasting agent is achieved on the surface to be treated, but also the wear on the impeller and the acceleration of the blasting medium energy to be reduced.
  • Fig. 1 is shown in a schematic sectional view of an impeller 2, which is arranged in the interior of a metering sleeve 1 of a blast wheel of a blasting machine, not shown.
  • the impeller 2 has profile pieces 3, which are attached to one of the end sides of a first side window 4.
  • a second side window is assigned to the first side window 4 in the axial direction opposite one another, so that the profile sections 3 are arranged between the two side windows.
  • the profile pieces 3 can in principle also be integrally connected to the front side of the side window 4.
  • the profile pieces 3 are raised relative to the front side plane of the side window 4, ie they form elevations with respect to this plane.
  • each profile piece 3 is spaced from the respective adjacent profile piece 3 in the circumferential direction.
  • the profile pieces 3 each have two serving as blasting agent guide elements legs 5 and 6, which are connected to each other at their at least approximately to the impeller center or to the impeller rotation axis ends.
  • the legs 5 and 6 point with their free ends on the metering sleeve 1, wherein in each case between the legs 5 and 6 from the direction of the dispensing sleeve accessible cavities are formed.
  • the profile pieces 3 are distributed in the circumferential direction over the circumferential edge region of the end face of the side window 4 such that channels 7 are formed between adjacent legs of adjacent profile pieces.
  • legs 5 and 6 of a profile piece 3 may, as shown in a sector A of the impeller 2, describe a V-shape.
  • the legs 5 and 6 may also be connected to one another via a web 9, cf. Sector B, so that the profile piece 3 is formed approximately overall as a U-shape.
  • a variety of shapes are conceivable, such as an L-shape.
  • the otherwise closed dispensing sleeve 1 is circumferentially provided with a discharge opening 8.
  • blasting medium is guided via unillustrated feed lines in the axial direction into the center of the impeller 2.
  • the blasting agent is then guided radially outward along the channels 7 by the impeller 2, which is set into a rotational movement by means of a drive (not shown).
  • the blasting agent is finally discharged into the angular range of the blades of a blaster wheel, not shown.
