Definitions

  • the invention relates to a method for cleaning stone and metal surfaces according to the preamble of claim 1, and an apparatus for carrying out this method according to claim 14.
  • the invention relates to a method and an apparatus for cleaning surfaces contaminated and attacked by atmospheric influences Stone and metal, such as such facades or stone and metal monuments.
  • the stone surfaces cleaned according to the invention can have both artificial stone surfaces such as concrete surfaces or natural stone surfaces such as limestone or be granite surfaces.
  • a cleaning method with the features of the preamble of claim 1 is known from US Pat. No. 3,427,763.
  • a stream of pressurized water which was generated by means of a water pressure between 100 and 900 bar, sucks the blasting material in a mixing chamber from a channel entering the mixing chamber laterally, which has a grain size between 0.01 and about 3 mm and sand , Quartz, corundum, fly ash and the like can exist.
  • the water jet acts as a water jet pump and in this way draws in the particles.
  • the blasting material particles are carried by a water jet and are hurled against the surface to be cleaned, the blasting material particles should not simply collide with the surface to be cleaned. Rather, they should, at least for the most part, be carried along by the sprayed water, slide along the surface and in this way clean this surface.
  • a major disadvantage of this known method is that the material to be processed is removed too much. Accordingly, the known method is used primarily for cleaning coarse components, such as castings and the like, and also as a cutting-off method in which the water jet loaded with blasting material saws a gap through the workpiece to be separated. The known method is therefore for cleaning valuable objects, such as of historical buildings, monuments and the like. In practice, the known method cannot be carried out in such a way that only the top layer to be lifted is actually lifted off, but the material underneath is not impaired.
  • the invention aims to develop the known method in such a way that the cleaning of the object surfaces can be done faster on the one hand and on the other hand but in such a way that parts of the surface of the object are not removed or only to a negligible extent.
  • the cleaning is carried out flawlessly, i.e. without leaving any dirt residue, but also without discoloration and other adverse effects on the object surface, provided the method is used correctly.
  • the jet contains in addition to the water and the blasting material a high proportion of air, which is a multiple of the volume by volume, that the jet rotates about its axis, and that the jet under the influence of the Beginning of the jet under pressure in the air contained in it and the rotation expanded strongly sideways.
  • the jet emerging from the tool for carrying out the method thus has approximately the shape of a cone, in which the angle between the cone axis and a generatrix of the cone shell is generally between 20 ° and 40 °.
  • the jet contains a high proportion of air gives it the character of a water-in-air dispersion.
  • the air contained in it at the beginning of the jet under pressure expands immediately when the jet emerges into the open and acts on the conical one Fan out the beam on all sides.
  • the rotation of the air-jet-water mixture works in the same sense. This also drives the jet apart radially on all sides.
  • the cross section of the jet grows approximately proportional to the square of the distance from the point of origin of the jet.
  • the velocity component of the jet in the direction of the jet axis i.e.
  • the worker who cleans an object surface by means of a device producing a jet according to the invention no longer runs the risk that even if the jet is allowed to continue to act for a short time on a sufficiently cleaned object surface, it will be attacked inadmissibly. This makes it possible to continue cleaning stubbornly soiled areas without having to take into account neighboring, already cleaned areas.
  • An essential criterion of the method according to the invention is that it easily affects the hardness of the surface to be processed and cleaned can be adjusted. For example, if a limestone or marble facade is to be cleaned, the water pressure and thus the pressure of the air supplying the blasting material will be chosen to be low, while for cleaning hard surfaces, such as granite surfaces or hard bronze surfaces, the pressure may be chosen to be relatively high.
  • Another advantage of the invention over the prior art is that not only is the rotation and expansion of the jet imparting a considerable speed component parallel to this surface to the blasting material particles before it hits the surface to be processed, but moreover the abrasive Effect of the blasting material in the invention distributed over a much larger area than was the case with the slim beams according to the prior art. This also has an especially mild abrasive effect. Surprisingly, this only gently removing effect of the cleaning jet according to the invention is sufficient to quickly achieve a perfect cleaning by removing the layers of dirt.
  • the volume of air in the jet is advantageously approximately 200 to 1200 times the volume of water, with the volume of air naturally increasing sharply in the direction of jet progress due to the expansion of the jet.
  • the proportion of air remains essentially constant. It is advantageously 0.5 to 3 times the water content, the air content should be greater the greater the water pressure. Air fractions from 0.7 to 1.5 have proven their worth.
  • a cleaning jet according to the invention does not have the relatively dark color of the water loaded with the blasting material. Rather, such a beam appears white.
  • the jet according to the invention is preferably formed by producing a mixture of sharp-edged blasting material, water and air, which is under considerable excess pressure, in a mixing chamber, this mixture rotating offset about an axis and the rotating mixture is sprayed along the axis. In this way, good mixing of air, blasting material and water can be achieved in the mixing chamber. In the mixing chamber, however, a relatively high pressure is maintained, which is also used to push the jet out of the mixing chamber, provided that this pushing out is not effected by maintaining the kinetic energy of the water jet entering the mixing chamber.
  • the air in the mixing chamber is still at a pressure which is only slightly below the pressure at which it was fed into the mixing chamber, its volume remains correspondingly low. Immediately after the blasting material-water-air mixture emerges from the mixing chamber into the surrounding atmosphere, the air can expand and thus radially disperse the jet.
  • the method is preferably carried out in such a way that a jet of pressurized water is injected into the mixing chamber on the side of the mixing chamber opposite the outlet nozzle in the direction of the outlet nozzle, and that a compressed air stream carrying blasting material is directed obliquely towards the front from the water jet, such that the blasting center axis of the Air flow and the jet center axis of the water jet run at a distance from each other.
  • a jet of pressurized water is injected into the mixing chamber on the side of the mixing chamber opposite the outlet nozzle in the direction of the outlet nozzle, and that a compressed air stream carrying blasting material is directed obliquely towards the front from the water jet, such that the blasting center axis of the Air flow and the jet center axis of the water jet run at a distance from each other.
  • a substantial R o-tation is generated in the mixing chamber.
  • the rotation can also be generated differently, for example by injecting the water tangentially into a mixing chamber.
  • the method of generating the rotation set out above is preferred. This has the essential advantage that no excessive rotation is generated, since otherwise the blasting material particles would be torn too much into the outer edge areas of the generated jet.
  • the mixing chamber narrows conically toward the outlet nozzle, the latter counteracts the fact that, in the mixing chamber near its circumference, rotating blasting material particles also point radially inwards towards the mixing chamber axis on their way to the nozzle Get motion component. In this way, the blasting material particles are distributed quite uniformly in the conically widened jet, so that the cleaning action of the jet acts on the entire cross section of the impact on the surface to be cleaned.
  • the blasting material is preferably ground glass powder, which is correspondingly sharp-edged and has a grain size between 0 and 1 mm, better between 0 and 0.5 mm. To this extent, training according to claims 12 and 13 is preferred.
  • the invention also includes an apparatus for performing the method.
  • This device is characterized in claim 14.
  • the preferred embodiment is characterized in claim 15.
  • the execution of the method according to the invention is relatively simple.
  • the water supply with the desired pressure - for example of 50 bar - is initially set.
  • the blasting material-air supply is switched on, and the pressure of the air supplying the blasting material is increased until the jet, which initially emerges in the form of a rod or rod, turns white and assumes the shape of a cone.
  • the beam now has the structure used according to the invention, which is the one shown above essential advantages in terms of cleaning even sensitive surfaces.
  • the grain size of the blasting material is preferably distributed over the range from 0 to the maximum size according to a normal distribution curve.
  • the concept of the normal distribution curve reference is made to the book "Introduction to grain size measurement technology" by Bartel (Springer-Verlag, Berlin, Göttingen, Heidelberg, 1964), pp. 13 and 14.
  • the course of the normal distribution curve is advantageously one in which about half (by weight) of all grains have a size between one third and two thirds of the maximum size.
  • half of them should therefore have a grain size between 0.17 mm and 0.33 mm.
  • a mixing head 1 is shown, which is composed of a series of individual parts. These individual parts, which will be described in more detail below, are firmly connected to one another, for example screwed, soldered, welded, glued and the like.
