Abstract
The invention relates to a device for feeding blasting shots into the central area of a centrifugal wheel (1) in a shot blasting system via a feed pipe (3), whereby a distributing bushing (7) comprising a distributing opening (8) is provided in the central region thereof. An impeller (9) comprising discharge openings (11) rotates in the distributing bushing (7) together with the centrifugal wheel (1), wherein the shots which are to be accelerated enter in an axial direction, the feed pipe (3) for the shots discharges into the impeller (9) and is provided with a ring-shaped tongue (10) which protrudes into the impeller (9) in the region of the distributing opening (8).
Claims4
Apparatus for the feeding of blasting material via a feed line (3) into the central portion of the centrifugal wheel (1) of a blasting unit, whereby in the central portion there is provided a distribution sleeve (7) having a distribution opening (8), and in the distribution sleeve (7) there rotates, together with the centrifugal wheel (1), an impeller (7) having discharge openings (11), into which impeller the blasting material that is to be accelerated enters in the axial direction, characterized in that the feed line (3) for the blasting material opens into the impeller (9) and is provided with a trough-shaped tongue (10) that extends into the impeller (9) in the region of the distribution opening (8).
Apparatus according to one of the preceding claims, characterized in that in the center of the impeller (9) there is provided a stirring or agitation element that is operatively connected with the drive shaft of the centrifugal wheel (1).
