Problems solved by technology

A considerable amount of this particle hits the side discs and vanes and bounces back there like a ping pong ball, which not only has an adverse effect on the discharge velocity by the centrifuge impeller, but also leads to unevenness of the blasting medium on the surface to be cleaned distributed
Moreover, due to the impact of the shot blasting medium particles on the components of the impeller of the centrifuge, it is subject to strong wear

Embodiment Construction

[0009] The illustrated centrifuge impeller 1 is surrounded by a casing 2, an input pipe 3 leads into its central area, and the blasting medium such as quartz sand or steel pellets is conveyed to the centrifuge impeller 1 by means of the input pipe 3. Opposite to the nozzle of the input pipe 3, the drive shaft 4 of the centrifuge impeller 1 extends out of the housing 2.

[0010] The centrifuge impeller 1 has a side disk 5, which is fixed on the drive shaft 4 and has blades 6 on the surface opposite to the drive shaft 4. The inner end surfaces of these blades 6 adjoin a dispenser with a dispenser opening 8. Sleeve 7. A runner 9 or a central accelerator is rotatably and fixedly connected to the drive shaft 4 or the side disk 5 in the distribution sleeve 7, and a plurality of unloading openings 11 are formed therein. The shot blasting medium discharged from the input pipe 3 enters the runner 9 through the grooved tongue 10. The groove-shaped tongue 10 basically covers the area on the ...

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).

Description

Technical field [0001] The present invention relates to a device for conveying shot blasting medium to the center area of ​​a centrifuge impeller of a shot blasting equipment through an input pipe, wherein a distribution sleeve with a distribution opening is provided in the center area and a rotating rotor with an unloading opening is provided in the center area. The wheel rotates together with the centrifuge impeller in the distribution sleeve, and the shot peening medium to be accelerated enters it in the axial direction. Background technique [0002] A device equipped with a centrifuge impeller, such as known from DE-OS 2538228, is excluded by spraying a shot blasting medium composed of fine metal particles onto the outer surface of the metal rolled product before the protective coating is obtained. Rolling swarf and / or rust on the surface. In such a centrifuge impeller, not all particles of the shot blasting medium move radially and as parallel as possible to the blades outwa...
