Definitions

  • the object of the present invention is to provide a more effective method which can be performed more rapidly and is thus cheaper.
  • This object is achieved by the method as according to the main claim.
  • the inventor has found that heating of the piece of chewing gum to be removed, followed by mechanical action thereon, whereby the surface area of the piece of chewing gum is enlarged, and subsequently feeding an agent removing the adhesive property of the chewing gum brings about good results.
  • the piece of chewing gum to be removed is here initially heated, whereby it becomes soft, so that the mechanical action can take place more easily.
  • This heating is carried out in a more effective manner in that a liquid is supplied in addition to steam. It has after all been found in the prior art method and apparatus that heating of the chewing gum does not take place quickly enough. This is caused by the small heat capacity of steam.
  • the heat capacity of liquids is much greater owing to their density, so that they result in more rapid heating of the chewing gum.
  • the invention makes use of this property by supplying liquid and steam.
  • the use of water as liquid has the first advantage that it is inexpensive.
  • Another advantage is the fact that the water can be used not only for the liquid but also for generating steam. Because of this measure use can be made of a single supply tank for liquid, from both water and steam can be generated.
  • a further shortening of the time for heating the chewing gum is obtained when the steam and the liquid are at least partly supplied simultaneously.
  • the use of a surface tension reducer results in a more intimate contact between liquid and chewing gum.
  • the chewing gum is dissolved by applying a cleaning agent .
  • the use of a metal brush enlarges the surface area of the chewing gum.
  • the effect of the cleaning agent is hereby enhanced.
  • the adhesive property of the chewing gum is herein removed by the cleaning agent, so that the mechanical action can be more effective.
  • the whole piece of chewing gum is finally removed in this manner.
  • Essential to the invention is the fact that use is made of hot water, which is provided with a cleaning agent, and of steam. While it is known to even use a combination of water and steam for cleaning, the invention is distinguished herefrom by the use of a solvent dissolved in the water.
  • the chewing gum residue is hereby limited such that it releases from the surface to which it is adhered.
  • the mechanical action may then be formed only by a kind of scraping action for removal of the detached piece of chewing gum.
  • the invention also relates to an apparatus for performing a method according to any of the foregoing claims, comprising a steam generator and a hot water source which can both be connected by a hose to a spray lance provided with a brush.
  • This apparatus forms a good tool for performing the method according to the invention.
  • a restriction is preferably arranged between the connection to the tank for supplying liquid and the connection for the coupling to the spray lance.
  • Fig. 1 shows a cross-sectional view of an apparatus for generating steam and hot water which is used in the present invention
  • Fig. 2 shows a cross-sectional view of a nozzle used in the present invention
  • Fig. 1 shows a trolley 1 in which a tank 2 is arranged.
  • a tank 2 is arranged.
  • Such an apparatus is usually applied for generating steam for stearn-cleaning, and an example of such a cleaning apparatus is the "Robby 5000" type.
  • Trolley 1 is provided with wheels 3 on which the trolley rests.
  • Tank 2 can withstand a pressure of about 5 at .
  • On the top there is provided a filling opening 4 which can be closed pressure-tightly with a cap 5.
  • a heating element 6 is further arranged in tank 2 and, under the permissible water level, i.e. below the upper level of heating element 6, there is arranged an outlet connection 7 on which is placed an electrically operated valve 8.
  • a connection 9 which connects to an electrically operated valve 10.
  • the outlet connections of both valves 8, 10 lead to a connection 11 to which a flexible hose can be coupled.
  • This hose is connected to a lance, the underside of which is shown in figure 2. It is pointed out here that it is possible with the above stated apparatus to generate both water and steam.
  • the water is herein taken off through connection 7, while steam is taken off via connection 9. Both media are brought together in the external connection 11.
  • the steam will herein entrain the outflowing water.
  • a restriction 20 is arranged between the connection 7 for supplying water and the controllable valve 8. It is however also possible to arrange the restriction between the controllable valve 8 and the connection 11 for connecting to the coupling to the spray lance.
  • the diameter of the restriction lies in the order of magnitude of one millimetre. Except for the restriction, such an apparatus is otherwise per se known; the elucidation relates only to the components which are significant for the present invention.
  • Figure 2 shows the end 12 of a spray lance 13. The end 12 of spray lance 13 narrows so that the flow speed of the medium travelling therein increases. Placed connecting thereto is a curved part 14 which leads to a brush holder 15.
  • the bottom 16 of the brush holder is provided with bristles 17 manufactured from metal, preferably brass, while holes 18 are arranged in the bottom 16 for passage of the water-steam mixture.
  • the brush holder is easy to replace in the case of for instance wear of the bristles.
