Definitions
- This invention relates to a process for degreasing mechanical parts and a plant for implementing the process.
- One of these known processes uses a boiler containing the solvent, a grid on which the objects to be degreased are rested, this being positioned a certain distance above the surface of the solvent, and, positioned above the grid, a condenser formed from pipes through which water passes.
- the solvent vapour which is generated condenses on the objects deposited on the grid, to degrease them.
- they remain wetted with pure solvent because this reaches them always in a distilled state.
- the degreasing plant is usually completed by a device for recovering the solvent vapour from the air used for drying the degreased parts.
- An object of the invention is to obviate these drawbacks by providing a degreasing process which does not result in environmental pollution.
- a further object of the invention is to provide a process of low operating cost.
- the process according to the invention uses a plant comprising a sealed chamber 1 to which the following are connected:
- the condenser 11 is connected to the vacuum pump 9 by a line 12 and to an activated carbon filter 14 by a line 13.
- the perchloroethylene storage tank is also connected to a distillation unit, not shown on the drawing.
- the plant also comprises a plurality of valves and control devices, which fall within the normal knowledge of the skilled man and are not shown for simplicity of description.
- the plant for implementing the process of the invention operates as follows:
- solvent vapour is fed into the chamber through the line 4 to condense on the parts and penetrate into their interstices by virtue of the degree of vacuum.
- Solvent in the liquid state is then fed in through the line 2 from the storage tank 3. During this stage the parts are rinsed and any dirt still adhering to them is removed.
- Solvent vapour is then again fed into the chamber 1, to condense on the parts and dissolve the final dirt.
- Vacuum is then again created in the interior of the chamber 1 by the pump 9 in order to totally evaporate the solvent, which is fed to the condenser 11 operating at low temperature.
