Definitions

• the invention relates to a device for removing dirt, in particular oil, extreme dirt, etc. on a surface, in particular on a road surface, wherein the device is integrated in a vehicle or associated with this, with nozzles for spraying cleaning fluid, brushes for mechanical processing the soiled area and a suction device for sucking the emulsion containing the detached dirt.
• the invention relates to a method for removing dirt, in particular oil, extreme dirt etc. on a surface, in particular on a road surface.
• Dirty roads are a very high risk of accidents, especially if they are contaminated with oil or similar substances that reach the roadway, for example by accident vehicles. After traffic accidents, it is therefore necessary to eliminate any soiling as quickly and thoroughly as possible, so that the road can be released for traffic again. Also in factory halls or parking garages again and again larger areas must be cleaned of dirt, which are caused by machines or vehicles.
• the scrub-wet suction cleaning has the disadvantage that in practice usually several operations are necessary to achieve a satisfactory cleaning.
• Another disadvantage is the high use of cleaning agent concentrate, which leads to an extreme environmental impact. When cleaning surfaces by high-pressure technology is problematic that this process requires large amounts of water. This leads to high disposal costs for the resulting wastewater and a short range of cleaning vehicles.
• Another disadvantage of this method is that the surface of the surface to be cleaned can be damaged by the high water pressure.
• the present invention is therefore an object of the invention to provide a device and a method for removing dirt of the type mentioned in such and further, that with little use of cleaning fluid surface-friendly, residue-free removal of dirt is possible, with the lowest possible energy consumption.
• the generic device for removing dirt on a surface is characterized in that the cleaning liquid is heatable by means of heat exchangers on the waste heat of the vehicle.
• the heating of the cleaning liquid requires that it be used to a much lesser extent.
• a further inventive manner has been recognized that it does not require the heating of the cleaning liquid external heat sources, but the waste heat of the vehicle is sufficient to bring the cleaning fluid to the required temperature.
• Another advantage is that the use of warm cleaning fluid in combination with the conventional scrubbing-suction-wet cleaning enables a surface-friendly removal of dirt.
• the low use of cleaning fluid leads to low disposal costs and a long range of the device according to the invention.
• the thermal energy of the cooling water and / or the exhaust gases of the vehicle can be used to heat the cleaning fluid - depending on the vehicle type.
• permanently hot water is provided in a short time, so that a removal of dirt is possible regardless of the prevailing outside temperatures.
• the energy costs for heating the cleaning fluid are completely eliminated.
• the use of water or a mixture of water and cleaning agent is advantageous, depending on the underlying soiling.
• the admixture of an oil-soluble surfactant to the cleaning liquid offers.
• the device for spraying the preheated cleaning liquid comprises a spraying device, which consists of several nozzles, wherein the nozzles are preferably individually controllable.
• a spraying device which consists of several nozzles, wherein the nozzles are preferably individually controllable. This makes it possible to dissolve the dirt in advance of a mechanical cleaning. Due to the individual control of the individual nozzles, these can be specifically adjusted to particularly heavily soiled partial areas.
• the brushes for the mechanical processing of the soiled area comprise outlet nozzles, through which they are sprayed with preheated cleaning liquid.
• a particularly gentle surface cleaning with low consumption of cleaning fluid and thus low disposal costs is given.
• the additional warm cleaning liquid is rubbed into the soiled surface with brushes.
• high-pressure nozzles are provided for discharging cleaning fluid under high pressure, which are preferably designed as wide-jet nozzles.
• the wide jet nozzles are operated by a high-pressure pump.
• the high-pressure pump allows a fast filling or emptying of the device with cleaning fluid.
• the suction device is automatically lowered to the surface to be processed, so that the leader of the device does not need to focus on this.
• the risk of accidents is increased, which increases with the number of different tasks that are put to the driver.
• edge areas such. As curbs, individually controllable front and side nozzles are provided. As a result, the device is also suitable for use in urban areas, where in particular after traffic accidents often curbs and narrow sidewalks need to be cleaned.
• a recycling system which reprocesses the suctioned, the dirt-containing cleaning liquid to the extent that it can be used again. As a result, costs are saved and the environmental impact is significantly reduced.
• the single figure shows a schematic view of the device according to the invention for removing dirt, which is integrated into a - not shown - vehicle or assigned to this.
• water is used as the cleaning liquid, and any other type of known Cleaning liquid or a mixture of different liquids can be used.
• the cleaning water is stored in a tank (1) and is fed via a line to the heat exchanger (2).
• the heat exchanger (2) uses the thermal energy of the cooling water and / or the exhaust gases of the vehicle to heat the cleaning water.
• the hot water is then fed via lines the brush (3) or a switchable high-pressure pump (4).
• the high-pressure pump (4) supplies several high-pressure nozzles (5) with pressurized hot water. Depending on the type and degree of soiling, the driver selects the brushes (3) and / or the high pressure nozzles (5) to clean the surface.
• the dirty water containing the detached dirt is sucked from the surface via a suction device (6), which is driven by a suction turbine (7), and fed into a recycling system (8). There, the dirty water is cleaned and returned the purified water in the tank (1). It should be noted that hot water which is not required can also be returned directly to the tank (1) via a line (not shown) from the heat exchanger (2).
• preheated cleaning liquid can be sprayed onto the soiled surface from a heated spray tank (11) via a spray device (10) comprising several nozzles (9) in order to dissolve the dirt.
• the Vorsprühtank (11) may either have a separate heater or be connected to the heat exchanger (2).
• Coarse dirt - such as granular oil binder - is fed via a sweeping roller (13) to the hopper (14).
• the content of the debris hopper (14) can be disposed of separately, reducing disposal costs.
