Abstract
An airless blaster arrangement (100) for the surface treatment of objects with blasting agents, comprising an airless blaster (10) consisting of several radially arranged thrower blades (11) which are secured to at least one side disk (14). An area (12, 13) for the projection of blasting agents is respectively provided between two thrower blades. A distributor element (20) with a star-shaped cross-section formed by several guide ribs (21) extends coaxially with respect to the airless blaster (10) and is connected thereto in rotationally fixed manner. One guide rib (21) of the distributor element (2) is respectively joined to a thrower blade (11). A blasting agent guide channel (22) of the distributor element (20) leads into the blasting agent projection area (12).
Claims12
In an airless blaster arrangement for surface treatment of objects with blasting agent, said arrangement comprising:
- a blasting agent supply tube,
- an impeller wheel comprising several axially-positioned thrower blades that are attached to at least one side disk, wherein a blasting agent discharge area is enclosed between each pair of thrower blades,
- the improvement wherein a distributor with a star-shaped cross-section formed from several guide blades extends coaxially with the impeller wheel and is connected with it so that it rotates with the impeller wheel, said distributor being surrounded by a fixed shell tube which has an aperture in a sidewall thereof at its periphery to which the supply tube is connected;
- wherein each guide blade of the distributor is connected to a thrower blade of the impeller wheel;
- and wherein a blasting agent guide channel of the distributor formed between each guide blade opens into an inner blasting agent discharge area of the impeller wheel.
