Definitions
- the present invention relates to a beam device for machining workpiece surfaces using a granular abrasive, with a rotatable Centrifugal wheel with centrifugal blades, with one that Centrifugal wheel with the exception of an abrasive discharge area surrounding centrifugal wheel housing, with a feed line for the feeding of the abrasive, with a the centrifugal wheel rotating radially inside the Centrifugal blades arranged in centrifugal blades, into which the supply line opens and with several breakthroughs in their scope, through which the blasting media supplied into the gaps between two neighboring centrifugal blades.
- a beam device of the type mentioned is from the utility model DE-U1 858 683 known. With this beam device the abrasive passes through a feed pipe towards the blasting agent inlet of the blasting device. Immediately before entering the beam device the supply line for the blasting medium opens into a Compressed air supply line. Through the through the compressed air supply line The blasting agent is supplied with compressed air accelerated and by a non-rotating, narrowing Nozzle tube towards the center of the centrifugal wheel promoted. The nozzle pipe ends immediately in front of you with the centrifugal wheel rotating feed wheel, which in its Scope has several openings, the passage of the blasting agent-air mixture in the radial direction serve outside.
- a sleeve-like Radially outside the nozzle tube and the metering wheel is a sleeve-like at a short distance from it Fixed housing.
- the sleeve-like housing has approximately congruent with the openings in the Allotment wheel an allotment recess in its extent, by which the blasting agent-air mixture continues radially outwards reaches the area of the rotating centrifugal wheel.
- the sleeve-like housing has a Ab technologicalaus brieflyung. This discharge opening is in the axial direction offset relative to the centrifugal wheel so that the Discharge recess seen in the axial direction in front of the centrifugal wheel is positioned.
- the laxative opening then opens in a space between the centrifugal wheel and a housing surrounding the centrifugal wheel is formed.
- the laxative recess is used here, an excess of to remove the supplied blasting agent-air mixture to blockages the beam device by an excess of to exclude the abrasive supplied.
- Such one Excess blasting media supplied can be relative here easily occur because the compressed air supplied for a effective promotion of abrasives in the center of the Centrifugal wheel ensures, in order to avoid a lack of abrasive in practice the supply of the abrasive generally preferred to be set a little higher than necessary becomes.
- This deliberate excess of fed Abrasive is here unless it is excessively large is not harmful because the excess of abrasive, as explained above, harmless through the laxative recess, but also for machining the workpiece surface useless, is dissipated.
- the object of the present invention is a beam device of the type mentioned create, with a simplified working method a more efficient Use of the abrasive used becomes.
- a simplification of the beam device according to the invention is achieved primarily by: their operation does not require the supply of compressed air, with which also the provision of production facilities of compressed air at the location where the jet device is used more is needed.
- By eliminating the compressed air can also appropriate line connections, such as Compressed air hoses, eliminated, which makes the handling of the Beam device is simplified.
- a particularly effective one Function of the beam device is achieved that through the air inlet opening or openings air into the incoming blasting medium in the guide sleeve initiated and in the center of the beam device with the Abrasive is mixed, making it very light and mixture of air and abrasive that can be conveyed with little resistance will be produced.

- the Blasting device is advantageous to the blasting agent Air to be mixed from an area close to the blasting agent ejection area deducted, which is advantageous a certain Deduction of generated dust from a workpiece surface material removed. So that becomes a cleaner operation of the beam device in comparison achieved to common facilities.
- the centrifugal wheel and the distributor sleeve by a motor flanged to the outside of the outer housing are drivable, the motor on an end wall of the outer housing is arranged, the supply line for the abrasive in the opposite, other end wall of the outer housing and the supply line as Tube formed with a tube flange and detachable with the associated end wall is connected.
- the invention further proposes that the supply line forming tube in an arc between about 30 ° and 60 ° coming into the outer casing from above and pointing substantially in or near the axial direction the starting area of the distributor sleeve ends.
- Gravity can be exploited, which special conveyors dispensable on the supply line side makes.
- the end region of the feed line facing the distributor sleeve is formed with a step, an upper Part of the end area shorter and a lower part of the end area is trained longer.
- the guide sleeve, as well as the distributor sleeve and the Centrifugal blades of the centrifugal wheel in operation Wear is for the purpose of easy interchangeability the guide sleeve provided that this on her supply end on the supply side with a mounting flange is formed, which is detachably connected to the outer housing is.
- this preferably consists of two interconnected parts, namely one hollow cylindrical sleeve part made of an abrasion-resistant material and from an associated flange part from a less abrasion-resistant, easier to edit material.
- This is only advantageous for those who actually use the hollow cylindrical sleeve part stressed the abrasion-resistant, much more expensive material used, while for the one not used by the abrasive Part of the guide sleeve a less abrasion-resistant, lighter editable and also cheaper material used becomes.
- the guide sleeve or possibly at least their sleeve part a sintered metal or ceramic. These materials are particularly resistant to abrasion and therefore particularly good for the heavily used guide sleeve or its hollow cylindrical one Suitable sleeve part.
