Definitions

  • the invention relates to a device for removing dirt, particularly oil, extreme soiling, etc., on a surface, particularly a road surface, with the device being integrated in or allocated to a vehicle, comprising nozzles for spraying cleaning liquids, brushes for a mechanical processing of the soiled surface, and a suction device for suctioning off the emulsion containing the dissolved dirt.
  • the invention relates to a method for removing dirt, particularly oil, extreme soiling, etc., on a surface, particularly a road surface.
  • the wet scrubbing method is disadvantageous in that in practice usually several processing steps are required to reach a satisfactory cleaning result.
  • the high consumption of concentrated cleaning solution is also disadvantageous, which leads to extreme environmental contamination.
  • This method needs large amounts of water. This leads to high disposal costs for the developing waste water and a short range of operation for the cleaning vehicles.
  • this method it is additionally disadvantageous that by the high water pressure the surface to be cleaned may be damaged.
  • the present invention is therefore based on the objective to provide a device and a method for removing soiling of the type mentioned at the outset equipped and further developed such that with a small amount of cleaning liquid the removal of soiling is possible while using small amounts of cleaning solution and a gentle treatment of the surface, with as little energy as possible being consumed.
  • the generic device for removing soiling from an area is characterized such that the cleaning liquid can be heated via heat exchangers utilizing the exhaust heat of the vehicle.
  • the invention it has first been recognized that by heating the cleaning liquid a largely reduced amount is sufficient. Additionally, it has been recognized according to the invention that no external heat source is required to heat the cleaning liquid, but the exhaust heat of the vehicle is sufficient to bring the cleaning solution to the required temperature.
  • the advantage develops that no energy must be provided to operate a separate heating device for the cleaning liquid. In particular it is possible to operate the device according to the invention at temperatures below freezing without adding any antifreeze means to the cleaning liquid.
  • Another advantage is given in the fact that by using warm cleaning liquid in connection with the conventional wet scrubbing method the soiling can be removed from the surface in a gentle fashion. The low amount of cleaning liquid leads to lower disposal expenses and a wide range of application for the device according to the invention.
  • the thermal energy of the cooling water and/or the exhaust of the vehicle can be utilized. This way, warm water is provided quickly so that the removal of soiling is possible regardless of the exterior temperatures.
  • the energy costs for heating the cleaning liquid are entirely omitted.
  • the device for spraying preheated cleaning liquid comprises a spray device, which includes several nozzles, wherein the nozzles can be controlled individually. This way it is possible to dissolve the dirt prior to any mechanical cleaning. By the individual control of the separate nozzles they can be adjusted to severely soiled sections in a targeted fashion.
  • the brushes for a mechanical processing of the soiled area include outlet nozzles, through which it is spray coated with the preheated cleaning liquid.
  • This embodiment allows a particularly gentle cleaning of the surface with a low consumption of cleaning liquid and thus low disposal costs.
  • the added warm cleaning liquid is gently rubbed into the soiled surface using brushes. This way, any soiling, particularly oil, is effectively removed mechanically from the road surface.
  • high pressure nozzles are provided to apply the cleaning liquid under high pressure, which nozzles being embodied as wide-jet nozzles.
  • the wide-jet nozzles are operated by a pressure pump.
  • the pressure pump allows a quick filling and/or emptying of the device with cleaning liquid.
  • the suction device can be lowered automatically to the area to be processed so that it is not necessary for the operator of the device to concentrate on this task. This way, the risk for accidents is reduced, which increases with the number of tasks to be performed by the operator.
  • edge sections such as curbs
  • individually controlled front and side nozzles are provided. This way the device is also suitable for operation within city limits, were particularly after traffic accidents frequently the curb and narrow sidewalks require cleaning as well.
  • a circuit may be provided, by which any unused, preheated cleaning solution can be returned into a reservoir. This considerably increases the range of the device.
  • a manual lance with a hose reel so that areas hard to access can be cleaned manually. After traffic accidents frequently not only the road is soiled but also guardrails, for example, or other hard-to-clean objects. They can quickly and reliably be cleaned using the manual lance.
  • a manually operated dome to be provided to suction hard-to-access areas.
  • a recycling system which reprocesses the suctioned cleaning solution containing the soiling to such an extent that it can be reused. This leads to cost savings and considerably reduced environmental contamination.
  • FIGURE shows, in a schematic front view, the device according to the invention for cleaning soiling, which is integrated in or allocated to a vehicle, not shown.
  • water is used as the cleaning liquid, though here any other type of known cleaning solution may also be used, or a mixture of various liquids.
  • the cleaning water is stored in a tank ( 1 ) and is supplied via a line to the heat exchanger ( 2 ).
  • the heat exchanger ( 2 ) uses the thermal energy of the cooling water and/or the exhaust of the vehicle to heat the cleaning water.
  • the warm water is then fed via lines to the brushes ( 3 ) or the high pressure pump ( 4 ), which can be switched on additionally.
  • the high pressure pump ( 4 ) provides several high pressure nozzles ( 5 ) with pressurized warm water. Depending on the type and degree of soiling, the operator selects the brushes ( 3 ) and/or the high pressure nozzles ( 5 ) in order to clean the surface.
  • the waste water containing the released dirt is suctioned off the area via a suction device ( 6 ), driven by a suction turbine ( 7 ), and guided into a recycling system ( 8 ).
  • the waste water is cleaned and the cleaned water is returned into the tank ( 1 ).
  • any warm water not required can also be returned via a line, not shown, from the heat exchanger ( 2 ) directly into the tank ( 1 ).
  • preheated cleaning liquid Prior to using the brushes ( 3 ) or the high pressure nozzles ( 5 ), preheated cleaning liquid can be sprayed from the heated pre-spray tank ( 11 ) via a spray device ( 10 ) comprising several nozzles ( 9 ) onto the soiled surface in order to dissolve the dirt.
  • the pre-spray tank ( 11 ) may either comprise a separate heating device or be connected to the heat exchanger ( 2 ).
  • Lateral brushes ( 12 ) with integrated pre-spraying nozzles are provided in the external edge section of the device so that even edgeless wet scrubbing of the surface is possible.
  • Coarse contaminants such as granular oil binders
  • a circular sweeper ( 13 ) to the debris container ( 14 ).
  • the content of the debris container ( 14 ) may be disposed of separately, thus reducing the disposal costs.
