Definitions

  • ABSTRACT A method of cleaning objects such as surfaces of a ve- 30 Foreign Application priority Data hicle and the like by passing a washing fluid, such as Nov 6 1971 Germany 2155278 water, which may contain a washing agent, through an atomizing nozzle to form' an atomized jet and then 52 U.
  • a washing fluid such as Nov 6 1971 Germany 2155278 water, which may contain a washing agent
  • the invention relates to a washing process with at least one washing jet directed at the object which is to be cleaned, said jet being emitted through a nozzle which atomises it.
  • washing agent is added to the washing jet and the washing liquid is preferably heated.
  • the washing action is improved in that greasy dirt particles are emulsified in a known manner by the additional washing agents.
  • a further limitation in the use of the known washing processes is that there must be means available for heating the washing liquid. This presupposes, in most cases however, an extra source of energy, for instance fuel, electric current or the like. Furthermore, because of the required heating means, the device for carrying out the known washing process is made considerably more expensive and is less reliable when in use.
  • the cleaning action will immediately be reduced so much that it will no longer be possible to obtain a sufficient cleaning effect with the known washing methods. This then becomes apparent when ,the dirt adheres firmly to .the object which is to be cleaned, as is for example the case with vehicles with dead insects or the like which hit the windows and the body when the vehicle is driven fast and stick firmly. These particles of dirt are very difficult to remove fully from the object which is to be cleaned even with conventional washing methods and even if the washing liquid is heated and washing agents are added.
  • the washing process according to the invention is characterised in that the jet of washing liquid passes through a magnetic field, the flux lines of which intersect the jet approximately perpendicularly. Under the influence of the magnetic field, magnetic moments which are directed against this field are also induced in atoms without a fixed magnetic moment. As the electro-dynamic theory shows, these diama'gnetic moments are proportional to the ordinal number of the element, the square of the radii of the path of electrons and the field strength.
  • the magnet arrangement can be constructed for this in such a way that the magnetic field is produced by two oppositely magnetised poles of a magnet arrangement, said poles surrounding the washing jet on at least two opposing sides.
  • the magnetic poles can be formed by two oppositely magnetised single magnets or by the two oppositely magnetised poles of a single magnet.
  • the magnetic field is produced by an annular magnet which fully en-.
  • annular magnet having suitably aligned-magnetisation.
  • the strength of the magnetisation is optimum because the drops of water in the atomised jet are subjected equally over the whole cross-section of the jet to the magnetic field.
  • the magnet arrangement can be constructed both as an electromagnet or electromagnets respectively or as a permanent magnet or magnets.
  • the cleansing action can be adjusted in a way which is not obvious by energising the electromagnet or magnets. This adjustment can be infinite or can be carried out in predetermined stages.
  • the magnet arrangement is constructed as a permanent magnet or magnets the same effect can advantageously be obtained if the magnet or magnets are positioned so that they can be adjusted perpendicularly and axially to the washing jet.
  • FIG. 4 shows in side view a nozzle with a magnet arrangement constructed in a different way
  • FIG. 5 shows the front view of the nozzle and of the magnet arrangement shown in FIG. 4.
  • the washing liquid 11 is conducted, with or without a washing agent addition, through a pipe to a nozzle 12 which is at the end of the pipe, the nozzle opening of said nozzle, 13 extending conically.
  • the cross-section is made very much more narrow at the inlet of the nozzle aperture and through this the atomising effect, which is in itself known, is produced in the washing jet 14 which is emitted.
  • the particles of water, indicated by 15 in the diagram depend in quantity and size on the dimensions of the nozzle 12, of the nozzle opening 13 and on the pressure of the washing liquid and on the cross section of the pipe 10.
  • the arrow V indicates the direction of the movement of the atomised water particles 15 and shows that these particles leave the nozzle opening 13 at a certain speed.
  • the washing jet 14 which is split up into the drops of water 15 now passes through a magnetic field 18 which is produced by the two poles l6 and 17, of opposite magnetisation of a magnet arrangement.
  • the flux lines of this magnetic field 18 are perpendicular to the centre axis of the washing jet which widens out concially.
  • the magnet arrangement is positioned so that it is connected directly to the nozzle opening 13. This has the advantage that the distance between the poles can also be kept small because the cross section of the jet is still small in this region, and this considerably increases the strength of the magnetisation, as is well known.
  • almost all the drops of water 15 cross the magnetic field approximately at right angles and this again has a favourable effect on the size of the induced voltages.
  • the effect of the magnetic field 18 on the water particles is characterised by the induction of voltages, as indicated by the drops of water 19 marked with the polarity signs and
  • the charged drops of water 19 hit a surface 20 which is to be cleaned and on which the dirt particles '21 adhere firmly.
  • These particles of dirt 21 may also be held firmly through electrostatic charges, as given by the polarity signs in the object to be cleaned and in the dirt particles2l.
  • electrostatic charges are equalised and thus the additional holding force of the dirt particles 21 is broken.
  • a magnetic moment is also induced in the water particles 15 under the action of the magnetic field 18. These moments are directed against the magnetic field and are the cause of the diamagnetism. These diamagnetic moments are proportional to the ordinal number of the element, the square of the radii of the path of electrons and the field strength, according to the electro-dynamic theory. This diamagnetism is not dependant on temperature and it exerts on the water particles the action which leads to a more effective removal firmly adhering dirt particles.
  • a pipe 31 for the washing liquid is shown in FIGS. 2 and '3, the end of said pipe being terminated with a nozzle 32.
  • This nozzle 32 is preferably screwed on or into the washing liquid pipe 31.
  • the nozzle opening discharges into a transverse slit so that the jet which is emitted is given a rectangular cross-sectionwhere one measurement can be very small in relation to the other measurement.
  • a sleeve 35 is secured so that it is axially adjustable by means of a retaining screw 36 on the nozzle 32.
  • An L-shaped curved piece of metal 34 is fixed on the sleeve 36 and projects with its free arm into the region in front of the nozzle opening.
  • a U-shaped permanent magnet 30 is screwed on this arm as indicated by the screw 37.
  • the lines of .flux which run between the poles of the permanent magnet 30 cross the water jet perpendicularly, and directly after it passes out of the nozzle 32.
  • the U-shaped permanent magnet 30 can also have means for receiving the nozzle 32 in the bar itself and can be secured directly on the nozzle 32 by means of an adjusting screw 33.
  • the poles of the permanent magnet 30 are in this case aligned to the broad sides of the washing jet. In this magnet arrangement also the lines of flux run perpendicular to the washing jet.
  • the magnet arrangement can of course also be formed out of single, opposed, permanent magnets where a further possibility for adjustment is provided, diagonally to the direction of the washing jet.
  • Electromagnets can also be used instead of permanent magnets, the energisation of these being infinitely adjustable or adjustable in predetermined stages.
  • a method of cleaning an object comprising passing a washing liquid through a nozzle to form an atomized jet of the washing liquid, passing the atomized jet of washing liquid through a magnetic field, the flux lines of which are substantially perpendicular to the axis of the atomized jet, to induce a voltage in the droplets of said atomized jet, and finally passing the atomized jet against the object to. be cleaned whereby the object is more effectively cleaned.
