Abstract

A pickling tool configured for pickling a surface of an element, comprising a supply conduit delimiting a supply channel configured to be in pneumatic communication with a source of compressed air laden with a powder of an abrasive product, a removal conduit delimiting a removal channel configured to be in pneumatic communication with a suction source, and a nozzle having an opening that communicates with an exterior and is configured to face the surface, wherein the nozzle is in pneumatic communication with the supply channel and the removal channel. Such a tool thus allows the passage of a flow of air for spraying the abrasive and the suction of the abrasive and of the powder arising from abrasion.

First claim

The invention claimed is:

1. A pickling tool configured for pickling a surface of an element, said pickling tool comprising:
a supply conduit delimiting a supply channel configured to be in pneumatic communication with a source of compressed air laden with a powder of an abrasive product,
a removal conduit delimiting a removal channel configured to be in pneumatic communication with a suction source, and
a nozzle having an opening that communicates with an exterior and is configured to face the surface, wherein the nozzle is in pneumatic communication with the supply channel and the removal channel,
wherein the supply conduit is an interior conduit and the removal conduit is an exterior conduit in which the interior conduit is accommodated, and
wherein the pickling tool comprises a guide that traverses the opening and is secured to the supply conduit.

2. The pickling tool according to claim 1 , further comprising a seal fixed around the opening.

3. The pickling tool according to claim 1 , wherein the opening is made at an end of the removal conduit.

4. The pickling tool according to claim 1 ,
wherein the supply conduit comprises a proximal part and a distal part,
wherein the proximal part is fixed and in pneumatic communication with the source of compressed air,
wherein the distal part is mounted movable in rotation at an end of the proximal part and opens out in the nozzle,
wherein the end of the distal part that opens out in the nozzle is closed off by a plug pierced with perforations traversing it, and
wherein the pickling tool comprises means for rotating the distal part.

5. The pickling tool according to claim 4 ,
wherein the means for rotating comprise an air conduit and fins,
wherein the air conduit delimits an air channel in pneumatic communication with the source of compressed air,
wherein the distal part carries fins that are arranged in the air channel in such a manner that a flow of air that circulates in said air channel interacts with the fins such as to cause the distal part to turn, and
wherein the air conduit opens out in the removal conduit downstream of the fins.

6. The pickling tool according to claim 1 , wherein the guide is removable.

7. A pickling system comprising:
a source of compressed air,
a reservoir containing a powder of an abrasive product,
a suction source,
a pickling tool according to claim 1 ,
a supply pipe extending between the source of compressed air and the supply channel traversing the reservoir, wherein the supply pipe comprises a charging system that makes it possible to extract powder from the reservoir and to inject it into a flow of air in the supply pipe, and
a removal pipe extending between the removal channel and the suction source.

8. A pickling tool configured for pickling a surface of an element, said pickling tool comprising:
a supply conduit delimiting a supply channel configured to be in pneumatic communication with a source of compressed air laden with a powder of an abrasive product,
a removal conduit delimiting a removal channel configured to be in pneumatic communication with a suction source, and
a nozzle having an opening that communicates with an exterior and is configured to face the surface, wherein the nozzle is in pneumatic communication with the supply channel and the removal channel,
wherein the removal conduit is an interior conduit and the supply conduit is an exterior conduit in which the interior conduit is accommodated, and
wherein the pickling tool comprises a guide that traverses the opening and is secured to the removal conduit.

9. The pickling tool according to claim 8 , further comprising a seal fixed around the opening.

10. The pickling tool according to claim 8 , wherein the opening is produced at an end of the supply conduit.

11. The pickling tool according to claim 8 , wherein the guide is removable.

12. A pickling system comprising:
a source of compressed air,
a reservoir containing a powder of an abrasive product,
a suction source,
a pickling tool according to claim 8 ,
a supply pipe extending between the source of compressed air and the supply channel traversing the reservoir, wherein the supply pipe comprises a charging system that makes it possible to extract powder from the reservoir and to inject it into a flow of air in the supply pipe, and
a removal pipe extending between the removal channel and the suction source.
