Definitions

  • the invention relates to a cleaning device for a substrate and a cleaning method for a substrate, in particular flat substrates with non-closed surface can be cleaned, such as artificial turf.
  • a method is known with which a substrate such as artificial turf can be cleaned.
  • a nozzle tube is provided with a plurality of individual nozzles, which form a liquid curtain by adjacent sprays. This meets at an adjustable angle to the ground in a strip-like or line-like impact area. The angle can be in a range of 15 ° to 30 °. Dirt particles entrained by the spray jets are thrown or rinsed on a pick-up lamp arranged just behind the impact area, ie moved, and can easily be transported away from there.
  • the disadvantage here is that the removal of dirt particles after the recording lamp may be difficult under certain circumstances.
  • the invention has for its object to provide an aforementioned cleaning device and a corresponding cleaning method for substrates with which problems of the prior art can be solved and it is possible in particular, from or from the ground dissolved or entrained dirt particles as simple and as complete as possible to be able to remove.
  • a cleaning device having the features of claim 1 and by a method for cleaning a substrate with such a cleaning device with the features of claim 14.
  • Advantageous and preferred embodiments of the invention are the subject of further claims and are explained in more detail below. In this case, some of the features are described only for the cleaning device or only the method for cleaning. However, they should be able to apply independently and independently of each other both for a cleaning device as well as for a method for cleaning independently.
  • the wording of the claims is incorporated herein by express reference.
  • the cleaning device with the particularly advantageous flat surfaces can be cleaned with non-closed surface, such as artificial turf, has two nozzle tubes, each having a plurality of individual nozzles for generating juxtaposed spray jets per nozzle tube. These individual nozzles may under certain circumstances form a liquid curtain.
  • the spray jets of the two nozzle tubes meet from different or opposite directions in a common impact area on the ground, the directions can be opposite viewed from above. Such an impact area is advantageously strip-shaped or linear.
  • the spray can hit each other directly. Alternatively, they can hit the ground with a distance of no more than 5 cm or no more than 3 cm from each other.
  • a suction device is arranged in order to be able to remove or suck off liquid spouting upwards and, above all, to be able to remove or suck off dirt particles or impurities which have been removed from the underground or from the substrate by the spray jets and entrained. These dirt particles or impurities can also splash up, so to speak, advantageously to a height of 3 cm or more above the ground. There they can then be detected well by the suction device arranged above or be sucked off.
  • the suction device has an elongated suction slot, which is advantageously approximately as long as the impact area.
  • the suction slot can be adjusted in height relative to the impact area. Additionally or alternatively, the suction slot can be adjusted in its width.
  • the first measure of the height adjustment can influence how many dirt particles or impurities or upwardly splashing liquid are sucked off.
  • the second measure of the adjustment of the width of the suction slot can essentially be used to set the speed of the air at the suction, which ultimately also influences the suction power for liquid and dirt particles or impurities.
  • the height and / or width of the suction slot can also be adjusted or adjusted during a cleaning process, for example, to changing factors such as the nature of the substrate or the amount of dirt particles.
  • height and width of the suction slot can be adjusted simultaneously and / or synchronously. This makes an adjustment easier with respect to finding an optimum value, possibly also with respect to the mechanical complexity of such adjustability.
  • Such an adjustability can be realized such that the suction slot automatically becomes wider when moving upwards, and at a Movement down automatically becomes narrower. As the suction slot moves downwards, it comes closer to the impact area, so that dirt particles released from the spray jets or entrained upward can spray less far to the side, so that they can also be caught by a relatively narrow suction slot. It should be added that in a narrow suction slot, the flow velocity near the suction slot is considerably higher, so that in turn means that the dirt particles sucked more towards the narrow suction slot and then sucked through this and thus can be removed.
  • the suction slot extends over the impact area or just above it, ie vertically above it. This is especially true for a line-like or linear impact area, which can be particularly advantageous exactly in the middle between the two nozzle tubes.
  • the suction slot may be substantially formed by the lower edges of two opposing Absaugwangen, which may be, so to speak elongated and parallel to the nozzle tubes extending surface components.
  • the suction cheeks can thereby be moved or moved linearly in such a way, in particular with a vertical component, that both suction cheeks can be moved toward a common line which runs parallel to their lower edge and parallel to the ground.
  • this common line the suction cheeks can be moved to or from her. It is possible that the suction cheeks are simultaneously and similarly displaced, so that, for example, only a single actuator is necessary and in particular problems with synchronization can be avoided.
  • this common line can also be below the impact of the spray jets, but it is advantageous above it. This makes it possible to make the suction slot actually very narrow, for example, with a width of less than 1 cm or even only 5 mm, the suction slot is still above the impact area and thus actually bring dirt or impurities up can be from the underground.
  • the lower ends of the suction cheeks are specially designed. It is thus possible for the outer edges facing away from the suction slot to be rounded.
  • Such a rounding can be wide or generous, possibly with a radius of 50% to 100% of the thickness of the suction cheek at this lower end. Through this wide rounding, so to speak, from the side approaching air very well and preferably without turbulence, so as quickly as possible, to flow around the lower end of the suction and thus also with great speed and therefore good suction the air above the impingement up swept up and so well sucked up dirt particles entrained.
  • An inner edge of the lower ends of the suction cheeks directly forming the suction slot can not have any rounding or only a slight rounding. This form is less crucial for the suction effect.
  • the aforementioned Absaugwangen are arranged on opposite sides of a downwardly open suction box. These outer sides can diverge from bottom to top and thus be inclined so that this inclination causes the path of movement of the suction cheeks towards each other during a downward movement or away from each other in an upward movement.
  • the inclination may in particular be mirror-symmetrical to a vertical. This is particularly advantageous, although the arrangement of the nozzle tubes with respect to distance to this vertical and height above the ground is the same.
  • linear guides or the like be provided on the outer sides of the suction box, where they are movable upwards or downwards.
  • these may be elongated slots in the suction cheeks, into which guide pins or guide projections extend, which protrude from the outer sides of the suction box.
  • the elongated slots are formed exactly along the desired direction of movement or define them. It is possible to interchange the arrangement of longitudinal slots in the Absaugwangen and guide projections on the outer sides of the suction box also.
  • the outer sides of the suction box do not necessarily have to simultaneously form the inner sides of a suction channel or suction chamber of the suction box. Rather, they advantageously form a structural unit or a structural unit with these inner sides, so that separate components can also be provided for the formation of the inner sides.
  • the suction box can have a plurality of suction connections at the top or at an upper side. These can be guided by means of one or more pipes to a suction device, as it is known per se for such cleaning devices. In such a suction device and dirt particles and liquid can be separated, so that in particular the liquid can be used later or directly again for the cleaning process. The dirt particles are advantageously collected in a separate store.
  • the Suction connections preferably go upwards from the suction box, wherein they can then also be angled relatively short behind it and if necessary can also be brought together, so that overall only one or two suction pipes lead to the suction device itself.
  • suction box subdivisions are provided such that they lead from an inner side wall of the suction box to another opposite inner side wall or extend.
  • These subdivisions extend not only from an inner side to the opposite, but also from top to bottom and in particular up to an upper side of the interior of the suction box.
  • This interior may be formed such that the subdivisions from the bottom up are strictly monotonously narrow or reduce their width.
  • the inner sides of the suction box may even be inclined in opposite directions to the respective aforementioned outer sides with the suction cheeks thereon.
  • This has the advantage that the flow velocity increases as a result of a reduction in the overall cross-section to a suction connection on the upper side, and thus liquid and dirt particles can be reliably sucked off and thus transported away.
  • the speed of the dirt particles is high due to the leaching by the hitting the ground spray, it decreases naturally on the way up or mandatory, in particular even after the cross section above the narrow suction slot can widen slightly again.
  • a renewed acceleration upwards is beneficial.
  • a suction connection is provided at the top of the suction box.
  • this may be three to six or even eight suction ports on the top, wherein suction regions below these suction ports, which are adjacent to each other, may be separated from each other by the partitions.
  • the nozzle tubes are adjustable in height above the ground and / or in their distance from one another.
  • This can be achieved by basically any guides or brackets for the nozzle tubes.
  • This is achieved by guide slots for the nozzle tubes in side walls or side plates, which are arranged at the beginning and at the end of the suction slot or the suction box.
  • the nozzle tubes have an adjustable angle of the spray jets to be cleaned underground.
  • the nozzle tubes can be rotated, for example, about a central longitudinal axis, so that at the same time changes the angle for all its spray jets at each nozzle tube.
  • the nozzle tubes may be moved in a guide or guide slot such that the orientation and thus the angle of the spray jets change to the ground. If the angle is larger, the spray jets can penetrate deeper into the ground and thus also transport deeper impurities or dirt particles upwards or tear them up so that they can be sucked off.
  • the danger may increase that, for example, in the case of a synthetic turf filled with sand or granules, too much of the backfilling is carried along as suction and suction and thus removed from the underground, which would obviously be detrimental.
  • This effect can, of course, be counteracted by a flatter angle of incidence and by the pressure of the spray jets being somewhat reduced.
  • a guide device for the nozzle tubes may be formed such that the nozzle tubes are adjusted identically and in opposite directions.
  • they are adjusted such that they are always arranged mirror-symmetrically to a vertical center plane, which extends through the impact area.
  • the nozzle tubes with their nozzles therein, in particular flat-jet nozzles can always also be arranged and aligned mirror-symmetrically to this center plane.
  • the guide device for the nozzle tubes have a vertically movable guide carriage, advantageously on both sides of the nozzle tubes.
  • the guide device may comprise a holding rod which extends from the guide carriage to each nozzle tube and advantageously has a connection with the nozzle tube, which lies in the extension thereof.
  • the guide device may comprise an adjusting rod, which also from the guide carriage to each nozzle tube runs, but advantageously by means of an articulated lever or the like. is connected to the nozzle tube, said compound is not in the extension of the nozzle tube.
  • Holding rod and adjusting rod can run parallel to each other, so form a kind of parallel guide for the nozzle tubes and their movement.
  • An articulation lever should be rotatably connected to the nozzle tube and ensure that this moves in a movement due to the support rod or twisted so that the angle of incidence behaves as desired, advantageously does not change.
  • the guide device and thus also holding rod and adjusting rod are advantageously designed such that upon adjustment of the guide carriage and thus changing the position of the nozzle tubes an angle of incidence of their spray jets on the ground always remains the same and does not change.
  • a cleaning and thus also a cleaning result can be optimized by changing the position of the nozzle tubes.
  • the two nozzle tubes move simultaneously and identically, ie always run symmetrically to a vertical center plane.
  • the spray jets are influenced by the height and width of the suction slot and possibly by a pressure on the nozzle tubes.
  • the guide carriage can be adjusted and the nozzle tubes can change their position, but advantageously such that the angle of incidence remains the same.
  • an angle of incidence of the spray jets in both nozzle tubes also differ, under certain circumstances it can also be adjustable.
  • an adaptation to different substrates or their degree of contamination can be achieved.
  • the nozzle tubes have flat jet nozzles, more preferably 5 to 15 flat jet nozzles.
  • the spray jets are flat jets, which lie essentially in one plane. A flat jet can therefore be fan-shaped or fanned out, so to speak.
  • the flat jets form a liquid curtain per nozzle tube, which radiates into the impact area. Due to the particularly advantageous symmetrical irradiation of the spray jets on or in the ground, the dirt particles are not only in the direction of the corresponding nozzle tube away slightly upwards or slightly slanted upwards, but so to speak, mainly upwards or even vertically upwards. They reach in a relatively narrow area above the impact area a sufficient height above the ground, for example, at least 3 cm, from which they can then be very effectively sucked by means of the above-described suction slot.
  • the individual flat jet nozzles can be designed to be adjustable, for example with regard to the cross section or width of the respective spray jet. So a profile can be set.
  • the respective spray jets formed by them from the two different directions can be symmetrical to a vertical plane along the impact area, preferably at the same angle to the ground.
  • a treatment device for treating the surface with liquid can be provided by applying this liquid.
  • a care liquid can be applied, advantageously a disinfecting liquid in order to disinfect the surface or an artificial turf during or after cleaning.
  • the treatment device has a tank and at least one discharge device with at least one discharge opening for the liquid and a line from the tank to the discharge device.
  • the discharge device may advantageously be a tube, for example a kind of spray bar, with a plurality of discharge openings thereon, particularly advantageously in the form of nozzle openings.
  • the discharge can be carried out with high pressure or with a slight overpressure, depending on the desired penetration depth.
  • a pump or a similar device for generating pressure can be provided, for example on the tank or on the said line.
  • the discharge device may preferably be arranged in the direction of travel of the cleaning device behind the suction device, in particular behind the rear nozzle tube. This prevents the liquid from being washed out again. It can be arranged on a chassis or frame, which also carries the nozzle tubes.
