of the patent for INDUSTRIAL INVENTION entitled:

? Equipment for washing airbrushes and / or for washing small pieces ?,

TEXT OF THE DESCRIPTION

AND? It has always been known that after use, spray guns must be washed to remove any residual traces of paint in order to ensure that they are efficient and well-functioning during subsequent use.

Are currently used paints whose solvent? L? water for which the washing in this case is carried out with clean water or detergent. In the event that the paints have a thinner as a solvent, the cleaning liquid will be? a suitable solvent.

In the market there are devices made for washing airbrushes and their components. or less complexes that are also protected by specific invention patents. In said market devices, washing is carried out both manually and automatically.

In the manual system, washing is carried out by means of a brush fed by water or solvent under pressure or by a gun with nozzle; in the automatic system the spray guns and their components are hit by a spray generated by suitably positioned nozzles, so? to invest and wash the objects indicated above in all their parts. Are the washing devices on the market quite elaborate and the volume of water (or other liquid) used? rather conspicuous; and the cost for the disposal of? water used as a special compound not? negligible.

L? 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.

L? dirty water is collected, treated with a coagulant for the floculation of the paint particles present and filtered, to then end up in the tank of the? water to be reused as clean.

This water after a series of uses, even if filtered, ceases to be clean and is also malodorous, and must be disposed of as a special residue by authorized companies.

How can you? to infer is the industriousness? structural of the device for washing today in the market and both the quantities? dell? polluted water that is created, require disposal with a non-negligible cost.

Purpose of this patent? to create an apparatus for washing airbrushes and their components and / or small pieces dirty with paints or the like, extremely simple, with a consumption of water (or other liquid) practically? insignificant to be eliminated preferably through an evaporation process avoiding the problem of disposal of the? dirty and polluted water (or other liquid) considered as special residues to be disposed of by authorized companies with the consequent high costs.

The equipment for washing airbrushes and their components or for washing small pieces? contained in a wrapper configured to C and you can? identify essentially in three parts.

The lower part where is the fraction separator, the intermediate part where is the area for washing operations and the upper part where is the? system for the supply of water (or other liquid) and pressurized air to feed the tools used by? operator who cleans the spray guns.

The removable type fraction separator? consisting of a kind of tray with a sealed bottom.

In the vicinity? of the bottom of the tray? placed a diamond-shaped grid. Above the aforementioned diamond point grill? loaded a layer of unit? filtering (which can be one or more paper cloths suitably studied in form and structure).

Above the units filtering there? a grid of flat shape that holds the said units together? filter elements and its surface constitutes the support surface that defines the washing compartment.

The washing area below? bounded by the flat grid of the fraction separator.

Airbrushes and / or other small objects to be washed are positioned on said grid.

All? inside the washing area? there is a gun with brush fed by water (or other solvent liquid), with any detergent, for the external washing of the parts to be washed, and a gun with nozzle for the internal washing (with water or solvent and any detergent) with water or solvent (and with air).

Said guns are fed by pipes that come out of the compartment of the washing area.

Are also present? on the ceiling surface a clean water outlet for rinsing and a drying air outlet and a shower-like outlet.

The lower surface of the upper part of the appliance constitutes the ceiling of the washing area.

In the upper part there are the paths of the various pipes, the valves, and the diverters and anything else concerning the pneumatic system connected externally with the network of the? water (and / or with a tank of solvent or water) and with l? plant dell? compressed air. Said pneumatic system feeds through pipes the? water or solvent and l? air to the guns and nozzles and sprayers in the washing compartment.

For cleaning the spray guns, once the equipment has been activated with the? water or with the solvent and with l? air under pressure, l? operator acts on? airbrush to be cleaned by means of the brush gun (crossed by water or solvent) and by means of the gun with nozzle fed by water or solvent and then by means of pressurized air. At the end the washing is completed with rinsing and blowing.

During the? entire cleaning operation, the dirty liquid and the rinsing liquid (in all at most about? of a liter) falls on the units? filtering of the fraction separator below.

The capacity absorption capacity of the separator? about 2 liters. Once the absorbent capacity of a separator is exhausted, it must be replaced with an intact one. The exhausted one can? be placed in a place that favors l? evaporation of the fraction d? water or solvent contained in it (for example in an oven while the paint applied to cars is drying). In this way the separator can? still be used for another spray gun washing cycle, replacing, if necessary, only the first or only the first two units? filtering, if these appear to have a lot of dried paint on the surface that affects the passage of the liquid to the units? underlying.

With the washing equipment of the patent there is no dirty water (or solvent) to be disposed of by specialized companies, why? the little water (or the little solvent) used is eliminated by evaporation.

The units filtering, dirty with dry paint, when they are no longer? permeable are removed, with the masking paper that is used by the body builder in the painting of the machines by adopting the same removal procedure.

What was previously described is clarified by? examination of the attached tables of the drawings.

Fig. 1 shows the casing seen from the side and fixed to a load-bearing wall in which casing below is a series of extractable drawers each relating to a fraction separator, in the middle the washing compartment equipped with guns and rinsing equipment and above the ? pneumatic system for the supply of water and air for the washing cycle.

Fig. 2 shows the casing of fig. 1 resting on a surface by means of feet applied to the base.

Fig. 3 shows an axonometric view of the casing shown in fig. 1 and 2 and a special base suitable to support it.

Fig. 8 shows an off-site washing gun with nozzle held by an operator.

Fig. 9 shows a water gun fitted with a nozzle applied to the? airbrush for cleaning its inside. Fig. 10? L? enlargement of the detail of the? uggello in contact with l? airbrush of fig. 9.

Fig. 1 1 shows l? rinsing operation of the? spray gun with spray.

Fig. 12 shows l? blowing operation of the? airbrush with air.

Fig. 13 shows the rinsing of the? airbrush with shower.

Fig. 14 shows the fall of the liquid on the units? filtering of a fraction separator following the cleaning of an airbrush by means of a gun with brush and a gun with nozzle.

Fig. 15 shows in section an enlarged portion of a fraction separator from which you can see the bottom of the container, the grid set aside from the bottom that supports the units? filtering, the unit? filtering and the upper flat grid that keeps the units compact? filtering.

Note that in the fraction separators instead of unit? Filters consisting of sheets of paper can be used as other absorbent materials, wood sawdust chipboard, cellulosic wadding and any other absorbent material capable of fulfilling the specific characteristic of absorbing qualitatively and quantitatively what is required in the specific case.

To proceed with the cleaning operations of the spray guns or other small pieces to be cleaned, proceed as follows.

Once the casing of the appliance 1 has been installed by fixing it to a load-bearing wall 2 or by placing it on a worktop 4 or by placing it on the appropriate base 3, it is connected the? pneumatic system 17 both to the air line 18 (not drawn) and to the water by inserting the washing tube in its seat (not shown) and inserting the rinsing tube in a? other specific seat (not drawn).

Done? connection to the? pneumatic system the control 8 located on the front panel 6 of the upper boxed part 5 opens where is 1? pneumatic system 17.

It acts on the pressure regulators 13, 14 until? the pressure gauges 9, 10, do not indicate the programmed pressure (preferably 3-3, 5 bar).

L? operator taken in hand l? spray gun 29 to be washed, activated the selector valve 1 1 presses the trigger of the brush gun 20, 24 until a regular flow is released for external cleaning.

So there operator presses the trigger of the gun 19, 24 with nozzle 27, 28.

L? operator activated the selector valve 12 rinses with nebulizer 30, with shower 31 and with air 32. All the liquid (washing and rinsing) used to carry out the entire cleaning cycle, falls 33 on the flat grid 35 of the separator of fraction 7? been absorbed by the units? filtering 34.

For the replacement of the fraction separator 7 exhausted the absorbent capacity of the units? filter elements 34 supported by the diamond-point grid 37 at the dripping limit on the tray bottom 36 is replaced with an intact one by taking it from the spare set placed in the drawers 38 of the base of the casing 1.

It should be noted here that while according to the above described as a cleaning liquid? been generally considered l? water (possibly with the addition of detergents) if the paints used by the airbrushes to be cleaned were of the water type, note that if the paints used by the airbrushes to be cleaned had been of the type whose solvent was different from? water also for cleaning the washing liquid would have been different from? water. Therefore, in the above description of the washing cycles, instead of the word "water", the word "washing liquid" must be used.

After what was previously explained, in addition to the novelty, the peculiarity? inventiveness of the invention which revolutionizes a by now consolidated system in the specific field of cleaning spray guns and / or small pieces where existing market equipment is complex and expensive and with which dirty liquid is obtained to be disposed of as a special residue with high costs. With the equipment of the patent l? washing and / or rinsing water is eliminated by evaporation and the few units? filters covered by the paint dried above are removed together and with the same system of masking paper that the body builders adopt when painting the vehicles.

Do you not leave the? inventive scope object of the? invention for any other solution, even for improvement, that a person skilled in the art could achieve if it falls within the scope of? scope of the same concept.
