Abstract

Device for cleaning aeronautical parts after machining or piercing includes an element for spraying a liquid on the part to be cleaned and an element for aspirating the oil-soiled liquid, chips and/or dust.

Claims

1. A pneumatic device for cleaning aeronautical parts after machining or piercing, said device comprising a pneumatic means for spraying a solvent on the part to be cleaned and a pneumatic means for aspirating the oil-soiled liquid, chips and/or dust, the control of the device being pneumatic.

2. The cleaning device as claimed in claim 1, wherein the solvent has a flash point below or equal to 300°

C., preferably below or equal to 110°

C.

3. The cleaning device as claimed in claim 1, said cleaning device comprising a means for filtering the soiled liquid allowing the filtration of the soiled liquid before it is stored.

4. Cleaning device according to claim 3, said device comprising a closed circuit allowing the soiled liquid, once retreated by filtration, to be reused by the spraying means.

5. The cleaning device as claimed in claim 1, wherein the spraying means comprises a gun fitted with a trigger (G), the actuation of the trigger (G) allowing the spraying of the liquid.

6. The cleaning device as claimed in claim 5, wherein the gun comprises a plurality of bristles (7) forming a brush (5), the jet of liquid originating from the gun being directed toward the bristles (7).

7. The cleaning device as claimed in claim 5, wherein the aspiration means comprises a duct (9) provided on the gun fitted with the brush (5).

8. The cleaning device as claimed in claim 1, wherein the aspiration means comprises a venturi-effect vacuum system.

9. The cleaning device as claimed in claim 1, wherein the air expelled from the device is filtered before it is discharged into the atmosphere.

10. The cleaning device as claimed in claim 1, wherein it comprises a control, situated in the vicinity of the trigger, making it possible to control a stoppage of the aspiration.

11. The cleaning device as claimed in claim 10, wherein the control comprises an orifice of which the blocking causes an overpressure, the overpressure causing the aspiration to stop.

12. The cleaning device as claimed in claim 1, wherein the trigger comprises at least one perfluorinated elastomer-based seal.

13. The cleaning device as claimed in claim 2, said cleaning device comprising a means for filtering the soiled liquid allowing the filtration of the soiled liquid before it is stored.

14. Cleaning device according to claim 13, said device comprising a closed circuit allowing the soiled liquid, once retreated by filtration, to be reused by the spraying means.

15. The cleaning device as claimed in claim 6, wherein the aspiration means comprises a duct (9) provided on the gun fitted with the brush (5).
