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, wherein the pneumatic means for spraying a solvent on the part to be cleaned and the pneumatic means for aspirating the oil-soiled liquid, chips and/or dust are comprised of:

i) a compressed-air inlet that accepts a supply of compressed air,

ii) a main tank (1) with a venturi system connected to the compressed-air inlet to receive the compressed air to create aspiration in the main tank, wherein the main tank holds a first portion of the solvent,

iii) a trigger-controlled brush (5) having a discharge connected to the main tank, wherein soiled solvent is aspirated through the brush into the main tank to add to the first portion of the solvent, aspiration of the soiled solvent brings chips and oils into the main tank,

iv) a screen located within the main tank above the first portion of the solvent, the screen filtering particles due to the chips and oils from the soiled solvent,

v) a pneumatic pump (2) connected to a solvent outlet of the main tank, and

vi) a solvent reservoir (2) connected to the compressed-air inlet to receive the compressed air to pressurize a second portion of the solvent contained in the solvent reservoir, the solvent reservoir having a solvent inlet in fluid communication with a discharge of the pump, and a solvent outlet in fluid communication with the control trigger of the brush, operation of the control trigger releasing pressurized solvent from the brush, operation of the pump decanting the first portion of the solvent from the main tank to the solvent reservoir, and

wherein the cleaning device has no electrical element.

2. The cleaning device as claimed in claim 1, wherein the solvent is Diestone and has a flash point below or equal to 110°

C.

3. 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, wherein the pneumatic means for spraying a solvent on the part to be cleaned and the pneumatic means for aspirating the oil-soiled liquid, chips and/or dust are comprised of:

i) a compressed-air inlet that accepts a supply of compressed air,

ii) a main tank (1) with a venturi system connected to the compressed-air inlet to receive the compressed air to create aspiration in the main tank, wherein the main tank holds a first portion of the solvent,

iii) a trigger-controlled brush (5) having a discharge connected to the main tank, wherein soiled solvent is aspirated through the brush into the main tank to add to the first portion of the solvent, aspiration of the soiled solvent brings chips and oils into the main tank,

iv) and a solvent reservoir (2) connected to the compressed-air inlet to receive the compressed air to pressurize a second portion of the solvent contained in the solvent reservoir, and a solvent outlet in fluid communication with the control trigger of the brush, operation of the control trigger releasing pressurized solvent from the brush,

the cleaning device has no electrical element, and

the solvent is Diestone and has a flash point below or equal to 110°
