Abstract
Disclosed is a blasting device for blasting a part of a turbine blade, which has a blade root, a blade platform and a blade airfoil, with a blasting cubicle, which has an insertion opening, a blasting unit for the discharge of accelerated blasting media into the blasting cubicle, and a mounting for the turbine blade, wherein a seal is provided, which seals a gap between the mounting and the blade airfoil in the region of the insertion opening and so prevents the escape of dust, which is created when blasting, from the blasting cubicle, and wherein the seal seals the gap from the inner side of the cubicle.
Claims15
A blasting device for blasting a part of a turbine blade having a blade root, a blade platform and a blade airfoil, comprising:
- a blasting cubicle having an insertion opening configured such that the blade airfoil is arranged partially inside and partially outside the blasting cubicle;
- a blasting unit that discharges accelerated blasting media into the blasting cubicle;
- a mounting arranged inside the blasting cubicle and surrounding the insertion opening, where the mounting receives the turbine blade;
- a seal arranged between the mounting and a platform of the turbine blade, where the seal seals a gap, from the inner side of the cubicle, between the mounting and the blade platform in a region of the insertion opening and prevents an escape of dust created during blasting;
- and
- a cap arranged on an inner side of the cubicle that fits over the blade platform and the seal such that the seal is protected against the blasting media.
