Methods for cleaning vehicles

The invention relates to a method for cleaning Vehicles in general.

Washing or cleaning for the purpose of removing the dirt that has settled on the surfaces to be cleaned, remove is commonly done by simultaneous mechanical

kali
and chemical-physical effects on those to be cleaned

Surfaces carried out.

There are already various solutions for performing this mechanical and / or chemico-physical Operations have been proposed.

In the case of the known devices with washing brushes, which can be arranged horizontally and / or vertically, For example, the mechanical operation is achieved through the brush bristles being drawn along and through the energy of the water jet, while the chemical-physical operations are effected by the temperature of the cleaning agent or as a result of the use of cleaning agents with special characteristics.

man

In other known solutions / has the energy of the ultrasonic waves or you have resorted to mixing water and air bubbles in the jet, to produce the mechanical effect, while the physical effect through electrostatic phenomena is produced.

The known solutions described above are used extensively, but they have different technical parts both from the point of view of its practical exercise and from the point of view of the results obtained thereby , e.g. because of the complicated structure of the necessary Facilities and / or because of the difficulty in making contact

The effect of the brushes on surfaces can be regulated and adjusted accordingly, which vary according to the vehicles Can have shapes.

The aim of the present invention is to provide a method for cleaning vehicles in general to create while using the combination of the various mechanical and chemical-physical operations involved in washing and cleaning are necessary, essentially the disadvantages of the known Solutions are avoided.

For the above purpose, according to the invention, that new methods of cleaning vehicles in general, characterized in that one sludge in suitable Distributed evenly on the surface to be cleaned in a manner that you can then remove the sludge together with the Dirt, which mixes with him by being sucked in, lets form a pasty mass and that you finally removes the pasty mass formed from mud and dirt with the help of jets of pure water.

The distribution of the mud on the surfaces of the vehicle that are to be cleaned can be advantageous in the form of rays in such a way that mechanical action causes a slight abrasion, a slight abrasion Scraping off the dirt is effected, with the peeling

409849/0278

the dirt from the surface of the vehicle to be cleaned and its adhesion due to physical effects absorption on the mud is facilitated.

According to another feature of the invention, the to surface of the vehicle to be cleaned by preparing them beforehand, i.e. before treatment with bathing or sprinkling the mud with a chemical cleaner.

The composition of the sludge, the temperature at which it is applied and the residence time of the Sludge on the surfaces of the vehicle to be cleaned naturally depend on the degree of soiling and can vary within wide limits without departing from the scope of the present invention steps out.

As preferred examples, which, however, are not intended to limit the scope of protection in any way, are to name the clay-containing sludge or the bentonite sludge as particularly suitable.

In the process of cleaning or bagging vehicles According to the present invention, the mud that is removed from the surface of the vehicle is in the form of a pasty mass together with that forming the pollution

4098 4 9/0278

Material, recovered and in a later treatment other surfaces to be cleaned are used again.

Separating the sludge from the pollution

forming material

can advantageously be carried out in suitable collecting basins or sumps according to methods known per se.

The devices for practicing the method according to the invention can be in various, arbitrary ways can be practiced using the conventional technique, for example by using known devices with so-called Washing bow ("Arco di lavaggio") is used with spray nozzles that are capable of mixing jets of water with solid particles to distribute.

Claims (1)

Expectations y procedures for cleaning vehicles in general, characterized in that sludge is distributed evenly in a suitable way on the surface to be cleaned, that you then remove the sludge together with the dirt to be removed, which is then absorbed or removed with it. Mixed absorption, a pasty mass can be formed and that finally the one formed from mud and dirt removes pasty mass with the help of jets of pure water. 2. The method according to claim 1, characterized in that the sludge on the surface to be cleaned in shape of rays distributed in such a way that in this way a slight abrasion or a mechanical effect the dirt particles are easily scraped off the surface to be cleaned. 5. The method according to claim 1 or 2, characterized in that that the sludge advantageously consists of clayey sludge or of Berfcm.itschlamm. 409849/0278 4 ·. Method according to one of Claims 1 to 3, characterized in that the surface to be cleaned is prepared by bathing or sprinkling them with a chemical cleaner before mud treatment. 5. The method according to one of claims 1 to 4, characterized in that the shape of a pasty The mass of sludge removed from this mass together with the material forming the pollution is recovered, by splitting the mass in suitable collecting or collecting basins or pans in a manner known per se and hereby separates the sludge from the material forming the pollution, the sludge for a subsequent one Treatment of other surfaces is recovered.
