Definitions

  • the present invention relates to a method and the relative portable apparatus to clean metal and non-metal surfaces using sodium bicarbonate indistinctively matched with mineral or vegetable material.
  • sodium bicarbonate is preferable not only from an ecological point of view, but also it is very effective because it leaves the support unaltered even in case of polished surfaces.
  • this material is also particularly difficult to operate since it is notoriously subject to adhere to the surfaces of the tank in which it is kept and to create intermediate vacuums, with subsequent problems of discontinuity in the supply.
  • the present cleaning machines are conceived to operate with the sodium bicarbonate matched distinctively either with mineral material or with vegetable material because, having these materials very different physical, mechanical and particle-size features, they need different types of apparatuses.
  • An aim of the present invention is to overcome the cited drawbacks through a surface cleaning method that guarantees the perfect storing, inside the preset tank, of the sodium bicarbonate matched with the chosen cleaning material and, also, the continuous and regular supply of the said material from the spray gun when needed.
  • the claimed invention concerns a portable cleaning apparatus according to claim 1. This is used with the double aim both to allow the perfect storing of the sodium bicarbonate and of the chosen cleaning material, being inserted directly inside the respective tank, and also to be mixed with the above-mentioned abrasive product together with whom to reach the suitable spray gun.
  • a cleaning apparatus according to the preamble of claim 1 is disclosed in document EP 0119021 .
  • fig. 1 and 2 illustrate a vertical section and a bottom view of the claimed apparatus
  • fig. 3 and 4 illustrate the transverse sections XX and YY relating to fig. 1 .
  • a tank 1A is provided for the cleaning material, realized as a hollow cylindrical body 1 that, preferably obtained through extrusion, is closed on the upper side through a lid 2 provided with a slot 2A for the filling and the subsequent refillings of material.
  • the cylindrical body is completed in the lower part by a base 3 having a discharge opening 3A closed by a suitable trapdoor 4 and is also equipped with a couple of feet 5 and a couple of wheels 6 for the firm rest of the apparatus and for its easier transport.
  • the said cylindrical body 1 comprises, internally and for its entire length, a tank-compartment 1A and an adjacent duct 1B superiorly comprising two transverse holes, a first hole 1C and a second hole 1D.
  • the first hole connects the outside with the inside of the tank 1A ( fig. 3 ) while the second one only connects the outside with the duct 1B ( fig. 4 ).
  • the said compressed air reaches, from a compressor not represented in the illustrations and through the supply pipe 8, the anti-condensate filter 9 and the following treatment assembly 10, and then flows through the supply duct 11 up to the pressure regulator 12 and the above-mentioned inlet valve 13.
  • the air that passes through the first hole 1C fills a sort of compression 'pre-chamber', that is that space suitably left above the cleaning material, let in through the slot 2A of the upper lid 2, in order to realize a constant pressure onto the product and consequently its perfect storing inside the tank 1A.
  • the slot 2A is closed by a spring door 7 suitably applied underneath the lid 2 so that it can be opened exclusively towards the inside of the tank itself.
  • a mixing valve 15 completed, at the exit, by a nozzle 16 on which is suited to be fixed the flexible rubber hose carrying the spray gun 17 at its opposite end.
  • the said valve 15 receives inside its mixing chamber both the compressed air coming from the duct 1B above, through the outflow slot 3B suitably arranged on the lower base 3, and also the abrasive material coming from the tank 1A above, through the slot 3C suitably realised on the base 3 too.
  • the outflow of the above-mentioned material through the outlet slot 3C is made regular and continuous by the uniform thrust exerted by that part of air simultaneously let into the compression pre-chamber through the first hole 1C.
  • the said mixing valve 15 can easily adjust itself to the different physical, mechanical and particle-size features of the various cleaning material usable, offering thus the possibility to adjust the outflow by means of a wider or smaller opening of its manual valve 15A and making so the portable apparatus, on which it is installed, flexible.

Claims (5)

  1. Tragbares Gerät für die Reinigung von Oberflächen, versehen mit einem Behälterkörper (1), umfassend einen Speicherraum (1A) zur Aufnahme eines Scheuermittels, insbesondere Natriumbikarbonat, und eines Reinigungsmittels, sowie eine Rohrleitung (1 B) für den Druckluftstrom, und versehen mit einem Mischventil (15) zur Mischung des Scheuermittels mit der Druckluft vor dem Abfließen mittels entsprechender Spritzmittel (17), die dazu geeignet sind, an das Mischventil (15) angeschlossen zu werden, wobei die Rohrleitung (1B) dazu geeignet ist, den Druckluftstrom sowohl ins Innere des Speicherraums (1A), über das darin enthaltene Scheuermittel hinweg, als auch zum Mischventil (15) hin zu leiten, um eine wirksame Lagerung des Scheuermittels im Innern des Speicherraumes (1A) zu ermöglichen,
    dadurch gekennzeichnet, dass der Behälterkörper (1) als zylindrischer Körper ausgebildet ist, in dem der Speicherraum (1A) und die Rohrleitung (1 B) sich aneinander angrenzend entlang des gesamten Längsverlaufs des zylindrischen Körpers (1) erstrecken.
  2. Tragbares Gerät für die Reinigung von Oberflächen nach Anspruch 1, dadurch gekennzeichnet, dass die Rohrleitung (1 B) an ihrem oberen Ende ein erstes Querloch (1C) besitzt, das dazu geeignet ist, das Äußere mit dem Inneren des Speicherraumes (1A) zu verbinden, sowie ein zweites Querloch (1 D), das dazu geeignet ist, das Äußere nur mit der Rohrleitung (1 B) zu verbinden, wobei das erste und das zweite Loch (1 C, 1 D) jeweils dazu bestimmt sind, ein Drucklufteingangsventil (13) für den Luftstrom in der Rohrleitung (1 B) im Inneren des Speicherraums (1A) und ein Sicherheitsventil (14) für die Ausstoßung der überschüssigen Luft zu verbinden.
  3. Tragbares Gerät für die Reinigung von Oberflächen nach Anspruch 2, dadurch gekennzeichnet, dass der zylindrische Körper (1) am oberen Ende durch einen Deckel (2) verschlossen ist, der mit einer Einfüllöffnung (2A) zum Befüllen und anschließenden Nachfüllen des Reinigungsmittels versehen ist, und unterseitig durch eine Basis (3) verschlossen ist, die mit einer Luke und einem Paar Füßen (5) sowie einem Paar Räder (6) für den sicheren Stand und leichten Transport des Geräts versehen ist.
