Definitions

  • the present invention relates to a washing system for cleaning vehicle tires, in particular truck tires and / or vehicle undersides.
  • the washing system has a nozzle device for spraying the tire or underside with liquid for cleaning purposes, a roller device designed as a pair of rollers for driving the tires of an axle during the cleaning process, a catch basin for holding the liquid after the cleaning process and a pump device for recirculating the liquid to the nozzle device.
  • washing systems are used to clean vehicle tires, which have a robust structure that is suitable for daily rough operation and at the same time should ensure a high degree of cleaning of the tires.
  • Increasing attention is being paid to using such systems as environmentally friendly as possible.
  • Tires of construction site vehicles are frequently cleaned with a water hose before driving on public roads.

  • the water flows into the sewage system and places an additional burden on the sewage treatment plants and the environment.
  • a washing system for cleaning vehicles in which a multiplicity of supports formed from box profiles are arranged, in the intermediate spaces of which water jet pipes are arranged, which aim upwards.
  • This washing system inadequate cleaning of the tire surface can be achieved, since at the beginning of the cleaning process the tires are only sprayed tangentially in the upwardly directed water jet rollers and so the dirt sitting in the tread grooves is not sprayed out of the tires .
  • the washing system for cleaning vehicle tires known from DE 38 02 409 C2 has nozzles which form a spray angle of less than 60 degrees to the driving surface, the vehicle rolling over the system during the washing process. This enables a better cleaning effect for the tires, but this washing system also poses a not inconsiderable burden on the environment.
  • the invention is based on the problem of specifying a washing system for cleaning vehicle tires which is improved compared to the prior art mentioned.
  • this invention is accordingly characterized by a discharge device connected to the collecting basin for discharging the solid or quasi-solid dirt components which are detached from the tire or the underside as a result of the cleaning process and by at least one sewage treatment plant, into which the waste water present in the collecting basin can be introduced via a line connection.

  • the invention is therefore based on the knowledge that the wastewater collected in the sump can be further clarified by an additional sewage treatment plant downstream of the sump so that it can be used as so-called clear water in the same way as fresh water in the washing system or for other purposes .

  • the fresh water consumption, which is used in a washing system for cleaning the entire system is always available in a relatively large amount, desirably severely restricted.
  • the discharge of the solid or quasi-solid dirt components from the collecting basin means that the contaminated liquid, in particular water, itself has an already reduced degree of contamination.

  • This liquid can be fed into the collecting basin via a second independent pump device.
  • the walls of the collecting basin are kept free of dirt, in particular of a solid type, since the further nozzle device flushes these solid dirt components into the discharge device, from which these solid components can be conveyed out of the collecting basin.

Containers 112, 114 of this type are provided and are suitable for being transported from refuse vehicles to garbage dumps or similar collection points, to be emptied there and to be transported back to the same or another point of need.
  • the containers 112, 114 can be used in addition to one or more clarification towers 66 or preferably instead of such a clarification tower 66 in the present case.
  • the arrangement of the containers instead of the one or more clarifying towers 66 has the advantage that the dirt accumulated in them does not have to be reloaded and transported from the containers to another container, but that the container, in a manner known per se , with which the dirt particles present in it can be easily transported to a landfill or similar waste collection point.
  • the containers 112, 114 differ from comparable commercially available containers in that, in the present example, an intermediate wall 116 is provided in each of them. This intermediate wall 116 protrudes at right angles from a side wall 118 of each container and is connected to the bottom 120 of the container. The wall 116 does not run fully onto the opposite wall 124, so that in the remaining space 126 the water present in the container can flow from the right partial chamber 128 into the left partial chamber 130 (arrow 132).
  • By coupling the two containers 112, 114 to one another via a connecting line 134 four partial chambers are created, two chambers 128, 130 in the container 114 and two comparable chambers 128, 130 in the downstream container 112.
  • Subchamber 128 of the container 114 initiated. From there the water flows along the arrow 132 into the other part of the chamber 130. The dirty water thus flows through the container 114 twice in the longitudinal direction, the flow path could be extended further by arranging further partition walls. The longer the residence time of the dirty water flowing through the container, the more dirt particles can settle down in the bottom area of the container.
  • the water then flows from the container 114 via the connection line 134 into the downstream container 112. There, too, it flows through the container twice, namely once the water flows through the sub-chamber 128 and then once again through the sub-chamber 130
  • the sub-chamber 130 then flows the water, which has since been cleaned there, via the line 90 back to the washing system 10 or the nozzle devices. If two containers 114, 112 are not sufficient to achieve adequate cleaning of the discharged dirty water, a number of additional containers can be set up in a row in a corresponding manner. It is also possible to omit the partition 116 from one or more of these containers. This depends in particular on the degree of contamination of the water introduced and on the number of containers 112, 114 connected and provided downstream.
  • the line 90 can also open into another basin 140 (FIG. 5).
  • This basin 140 serves as a reservoir for purified water. From this container 140, the water present in the basin 140 is fed to the nozzle devices via a pump device 142. Depending on the size of the reservoir 140, water of any size can be made available for cleaning the vehicles. An additional water reservoir for purified water can still be provided below the bottom 36 (FIG. 3). Due to its inclined design, the floor 36 has a free space below it, which can be used as a storage 144 for purified water. In this way, the basin 140 could be made correspondingly smaller or a correspondingly larger amount of purified water could be made available for cleaning at short notice.
