Definitions

  • the cleaning liquid will be an appropriate solvent.
  • washing can be done manually or automatically.
  • washing takes place by means of a brush fed by pressurised water or solvent or by a gun with a nozzle; in the automatic system the spray guns and their components are hit by a spray coming from appropriately positioned nozzles, so that all the parts of the above-mentioned objects are reached.
  • the washing devices on the market are quite elaborate and the volume of water (or another liquid) used is quite large; and the cost for disposing of the used water as a special waste is quite large.
  • the water to be used is taken from a tank by means of a pump; or with the ejection system according to the Venturi principle.
  • the dirty water is collected, treated with a coagulant for the flocculation of the paint particles and filtered, to then end up in the water tank to be re-used as clean water.
  • the aim of this patent is to create equipment for washing spray guns and their components and/or small parts that are soiled with paints and the like, one that is extremely simple, with water (or another liquid) consumption that is practically insignificant, to be eliminated preferably through an evaporation process, thereby avoiding the problem of disposing of the dirty and polluted water (or another liquid) considered special waste to be disposed of by authorised companies with consequent high costs.
  • the equipment for washing spray guns and their components and/or small parts is contained in a C-shaped casing and basically has three parts.
  • the fraction separator can be removed and is composed of a sort of tank with a sealed bottom.
  • the lower part of the washing area is marked off by the flat grid of the fraction separator.
  • the spray guns and/or other small objects to be washed are placed on said grid.
  • a gun with a brush that uses water (or another solvent liquid), with a detergent if required, for washing the outsides of the pieces, and a gun with a nozzle for washing the insides (with water or solvent and any detergent) with water or solvent (and with air).
  • Said guns are fed by tubes that come out of the compartment of the washing area.
  • top cover surface there is an outlet for clean water for rinsing and an air outlet for drying and an outlet like for a shower.
  • the lower surface of the upper part of the equipment makes up the upper limit of the washing area.
  • the operator works on the spray gun to be cleaned using a gun with a brush (using water or solvent) and using the gun with a nozzle fed with water or a solvent, and then pressurised air. At the end the washing is completed with rinsing and blowing.
  • the absorption capacity of the separator is about 2 litres.
  • the absorption capacity of a separator is exhausted, it is replaced with a new one.
  • the used one can be put in a place that favours the evaporation of the water or solvent fraction in it (for example in an oven during the drying of the paint applied to cars).
  • the separator can be used again for another spray gun washing cycle replacing, if necessary, just the first or just the first two filtration units if these have a lot of dried paint on the surface that hinders the passage of the liquid to the underlying units.
  • the filter units that are soiled with dry paint are disposed of when they are no longer permeable, adopting the same disposal procedure as the masking paper that is used by the body repair worker in painting the cars.
  • the pneumatic system 17 is connected to both the air line 18 (not drawn) and the water line by inserting the washing tube into its housing (not drawn) and by inserting the rinsing tube into another housing (not drawn).
  • control 8 is opened on the front panel 6 of the upper box section part 5 where the pneumatic system 17 is located.
  • the operator having taken the spray gun 29 to be washed, activates the valve switch 11, presses the trigger of the brushgun 20, 24 until a steady flow comes out for cleaning the outside.
  • valve switch 12 Once the operator has activated the valve switch 12, he then rinses with a spray 30, with a shower flow 31, and with air 32.
  • the cleaning liquid is generally considered to be water (maybe with some detergent added) if the paints used by the spray guns to be cleaned were the water type, but if the paints used by the spray guns to be cleaned were solvents other than water, then also the cleaning liquid for washing would have been other than water. Therefore in the above description of the washing cycles in place of the word "water”, we should read "washing liquid”.
