Definitions

  • the invention relates to a method for cleaning a ground surface which has been contaminated, in particular with chewing gum, by mechanical action on the contamination by means of at least one brush moving under a hood and by supplying superheated steam to the contaminant to be purged. Furthermore, the invention relates to a device for cleaning a particular contaminated with chewing gum, fixed bottom surface with at least one driven to perform a brush movement, arranged within a bottom open hood cleaning brush, with a device for supplying superheated steam to the ground surface to be cleaned and with a device for suction dirt particles dissolved from the bottom surface.
  • the object of the invention is therefore to propose a method and a device with which not only stubborn dirt, in particular hardened chewing-gum residues, can be removed on a fixed floor surface, but that this is possible. without having to accept an excessively slow feed of the soil cleaning device.
  • the device-related object is achieved by an initially mentioned, generic device in which the at least one brush is disposed in a provided within the hood treatment chamber, which is laterally separated by an apron with a bottom-side seal of the outside of the treatment chamber hood areas, wherein the bottom-side seal the apron enclosing the treatment chamber is designed so that within the treatment chamber a makes hamperkeitsbad can be dammed, wherein the hot steam supply opens into the treatment chamber and at which the suction line of the suction device opens into a suction chamber located outside the treatment chamber.
  • a hot cleaning liquid bath is provided in a treatment chamber of a cleaning device for the duration of the cleaning process and maintained for the duration of the cleaning process. It is provided that this makes protestkeitsbad is maintained at a temperature at which even hardened chewing gum residues soften greatly.
  • superheated steam is introduced into the treatment chamber, preferably under pressure.
  • the superheated steam represents a precursor for the actual cleaning liquid, which is formed only by the process of condensing the superheated steam in the treatment chamber.
  • the temperature of the present in the treatment chamber for the purpose of cleaning cleaning liquid bath can be quite brought to temperatures of more than 90 ° C and maintained.
  • it is provided to supply the superheated steam at a temperature of 150 ° C.
  • a supply of superheated steam under pressure supports the cleaning process, since insofar as at the same time as the supply of thermal energy is also a mechanical effect made by the spray on the contaminant to be cleaned.
  • the process is carried out such that the filling level of the cleaning liquid bath in the treatment chamber does not exceed a maximum fill level.
  • a fill level height of the cleaning liquid bath is considered to be suitable between 3 mm and 15 mm, preferably somewhat less than 10 mm. For this reason, the cleaning liquid bath in the treatment chamber covers the bottom surface underneath in the desired fill level, like a film.
  • the hot cleaning liquid bath ensures a particularly effective heat transfer to a surface to be cleaned off or dirt adhering to it, for example hardened chewing gum residues.
  • the same applies to the claimed device not only the amount of heat available in the makesssenkeitsbad is considerable.
  • the heat also acts on the contaminant to be cleaned during the entire time of the brush machining, the height of which projecting from the bottom surface is less than the filling level of the cleaning liquid bath.
  • a contamination present in the cleaning liquid bath is roughened, as a result of which the surface thereof is enlarged and thus a transfer of heat from the hot cleaning liquid into the contamination is still favored.
  • An advantage of this concept is also that additives that support the Abcurisvon on the hot steam supply into the treatment chamber must be introduced. Rather, they can be added directly to the cleaning liquid bath. As a result, evaporation of additives, especially if they are harmful to health, avoided. Nevertheless, they can exert their effect in the cleaning liquid bath, namely by mixing it throughout the entire surface area covered by the cleaning liquid bath.
  • openings are provided as overflow openings in the height of the maximum desired filling level height of the cleaning liquid bath in which a treatment chamber enclosing skirt can escape through the dirty water from the treatment chamber into an adjacent suction.
  • leakage of dirty liquid from the treatment chamber into the suction chamber is also possible by means of both measures described above.
  • the To control fluid level within the treatment chamber through the hot steam supply is provided.
  • the cleaning liquid bath temperature will also be included in this control, so that it does not fall below a predetermined value.
  • it is provided in such a configuration that even with maximum superheated steam supply over a certain period of time, the intended maximum fill level of the cleaning liquid in the treatment chamber is not exceeded or can be exceeded.
  • a suction device is operated in order to suck off immediately emerging from the treatment chamber dirty liquid. Suction is thus carried out simultaneously with the implementation of the mechanical brush processing of the bottom surface.
  • the suction line opens into a suction channel provided adjacent to the treatment chamber, preferably in the feed direction of the cleaning device behind the treatment chamber.
  • a plurality of brushes supported by a common brush are arranged, which are driven to perform an oscillating reciprocating motion.
  • the oscillatory motion typically has its apex in such a configuration in a position of the two brush groups, if they are arranged one behind the other in the feed direction.
  • a mechanical brush processing of the floor surface to be cleaned takes place in two steps, in a first step when the first brush group is moved over the floor surface to be cleaned and in a second step when the second brush group moves over the floor surface to be cleaned becomes.
  • the special feature of this concept is that the two brush groups are spaced from each other in the feed direction of the device and thus is a period of heat and spray exposure without brush processing between the first brush processing and the second brush processing.
  • adhering contaminants are heated to their softening temperature by heat transfer from the cleaning liquid, so that they can be brushed off from the bottom surface by the subsequent brushing of the second brush group.
  • the hot steam is preferably supplied at high pressure, with a pressure of more than 30 bar is preferred. In one embodiment, a hot steam supply at 50 bar is provided.
  • the kinetic energy thus introduced into the treatment chamber is correspondingly high. Since the superheated steam outlet nozzles are preferably directed towards the floor surface to be cleaned, the superheated steam jet, with appropriate kinetic energy, impinges on the floor surface or on the dirt adhering thereto on. With such a pressure, the hot steam jet permeates the hot cleaning liquid bath at any rate with a considerable kinetic energy in order to be able to exert its intended task of pressure spraying onto the floor surface to be cleaned.
  • a suction channel for sucking out of the treatment chamber leaked dirty liquid serve the remaining components of the hood, which preferably surround the skirt of the treatment chamber circumferentially. In this way, a circumferential suction channel is formed.
  • the hood is sealed on the bottom side by a suitable seal.
  • this circumferential suction channel also serves as a thermal insulation. Under the sealing of the hood incoming ambient air is then sucked together with the dirty liquid and does not reach or at most only in a not significant extent in the treatment chamber. Since the cleaning device is designed and the method is carried out so that contaminated liquid escapes from the treatment chamber, there is also no danger in the extraction that heat is extracted from the cleaning liquid bath by the suction.
  • the introduction of the warm exhaust gases into the suction channel supports the insulating effect of the suction channel with respect to the relative to the temperature of the cleaning liquid bath relatively cool or even cold ambient air.
