Definitions

  • the invention relates to a municipal vehicle for flushing and cleaning channels and containers or the like, comprising a container with a sludge compartment and a process water compartment, the process water compartment being connected to a flushing hose through which water is conveyed by means of a pump device to the end of the flushing hose which can be provided with a nozzle head becomes.
  • a mobile disposal device is known from DE-U-88 06 703, in which water conveyed in a flushing hose by means of a pump device is heated by means of a heating means before it emerges from the flushing hose. Waste heat from the drive motor of the known device is used as the energy supplier for the heating of the water, so that only 60 ° C to 85 ° C warm pressurized water can be generated there, and thus possibly no significant heating of the water takes place in principle in the course of the drive motor of the device can.
  • a vehicle for cleaning roadway and sidewalk surfaces is known, this vehicle having two rotating nozzles arranged side by side has, which are supplied with water from a reservoir arranged on the vehicle and the nozzles spray the water while rotating onto the surface to be cleaned by means of an intermediate pump device.
  • the cleaning water can be heated before it emerges from the nozzles by means of a heat generating device, the water sprayed onto the surface to be cleaned partly being recaptured and returned to the vehicle's own water circuit.
  • the object is achieved according to the invention in that the water conveyed by means of a further pump device, which is connected to the process water compartment, in a further flushing hose before it emerges from the another flushing hose is heated by means of a heating means and the energy required by the heating means is provided by an energy source separate from the drive unit of the motor vehicle.
  • the advantage of the solution according to the invention consists essentially in the fact that, as desired, the construction of previous municipal vehicles of this type can in principle be maintained without changes, since only to improve the cleanability the water from the service water compartment, which is required for cleaning in the sense described above , is heated specifically, to the extent that it can perform its cleaning function as intended.
  • the heating can take place in the range of 155 ° Celsius in the steam stage, i.e. up to a temperature typically found in steam cleaners.
  • the heating means is advantageously formed by a fuel-operated device which operates on the principle of an oscillating fire heater, such a heating means having the advantage that it is able to deliver the thermal energy required for heating the water in a very targeted manner, in relation to the desired one Temperature of the water or water vapor and in relation to the amount of heated water or water vapor.
  • the water required for the cleaning process is first brought to the required and desired pressure by means of a pump device. It may be advantageous to use the pump device to drive electrically, for example from the electrical system of the municipal vehicle.
  • the pump device hydraulically and / or mechanically, i.e. either directly from the drive unit of the motor vehicle or through a drive unit to be provided separately, which in turn can be driven by fuel.
  • the detergent advantageously being received in a metering container, via which the detergent can be introduced into the conveying connection between the process water compartment and the pump device.
  • the detergent can be easily refilled if necessary, the dosing container also allowing simple checking of whether sufficient detergent is present.
  • Such an embodiment also has the advantage that, in the event of maintenance and malfunctions of parts of the heating means, pump device and the like combined in the functional unit, commercially available parts which are commercially available in this regard can be used, so that such an embodiment is also less expensive than with a solution that is fully integrated into the vehicle and directly adapted to it.
  • FIG. 1 shows: a schematic, vertical longitudinal section through the container of the sewer vehicle and a rinsing hose connected to the container for cold water and a rinsing hose connected to the container, which promotes heated water or steam to exit the rinsing hose.
  • the municipal vehicle shown only partially in the drawing consists of a container 10 carried by the vehicle chassis, not shown, which is subdivided into a sludge compartment 11 and a process water compartment 12, the subdivision of the two compartments 11, 12 in the container 10 by an extension piston 25 for adjustment variable departmental volume.
  • a container 10 carried by the vehicle chassis, not shown, which is subdivided into a sludge compartment 11 and a process water compartment 12, the subdivision of the two compartments 11, 12 in the container 10 by an extension piston 25 for adjustment variable departmental volume.
  • the municipal vehicle in addition to the outlet of cold water 19 or water at ambient temperature Via the line / delivery connection 13 to the flushing hose 14, brought about by the pump device 15, the municipal vehicle has a second line / delivery connection 23, which likewise opens into the process water compartment 12 of the container 10.
  • the end of the line / delivery connection 23 which points away from the service water compartment 12 is connected to a further pump device 17 which Water in turn promotes a heating medium 20, which is shown schematically here as a water heater. From there, the heated water 19 is in turn conveyed via the line 23, optionally via a hose reel 26 to the flushing hose 18, at the end of which a spray gun or the like, not shown here, can be arranged.
  • the pump device 17 for conveying the water 19 into the heating means 20, which at the same time serves to build up the pressure of the warm water 19 required for the rinse cycle, can be driven per se in any suitable manner, for example electrically, hydraulically or mechanically, specifically directly from Drive unit of the motor vehicle, not shown here, as well as by a separate drive unit either directly or electrically, hydraulically or mechanically, which can be accommodated, for example, in the functional unit shown in dashed lines.
  • the arrow directed to the pump device 17 symbolically represents the drive of the pump device by the various suitable drive means listed above.
  • the heating means 20 can also be arranged in the functional unit 24, the arrow pointing at the heating means 20 also symbolically representing the supply of energy to the heating means 20 in order to heat the water 19 flowing through the heating means 20 or to generate water vapor.
  • the heating means 20 is shown here as a continuous-flow heater, it can also make sense to provide a storage container for the warm water generated, in order to avoid the heating means 20 always being in operation even when small amounts of hot water 19 or water vapor are required put.
  • energy can be supplied to the heating means 20 in any manner, for example by operating the heating means 20 according to the principle of the fuel-operated so-called oscillating fire heaters. In principle, it may also be possible to supply the heating means 20 with energy in the form of electrical energy if, for example, electrical energy from a general electrical energy network is available at the place of use.
  • the functional unit 24 consists at least of the heating means 20, the pump device 17 and a drive unit (not shown separately) for operating the pump device 17 and for generating energy for operating the heating means 20
  • the drive unit can be, for example, an ordinary drive unit (diesel engine, gasoline engine) operated with liquid fuel.
  • the functional unit 24 can be designed and positioned on the vehicle in such a way that it can easily be removed from the vehicle for maintenance and replacement purposes, with only standardized line connections for the supply of the water 19, the removal of the heated water 19 and, if appropriate, standardized electrical connections need to be solved. Such a configuration also allows the use of standardized, commercially available spare parts Malfunctions and / or continuous replacement when the predetermined service life has been reached.
  • the inlet of a metering container 21, in which cleaning agent 22 is received can open into the line / delivery connection 23 from the service water part 12 to the pump device 17.
  • the cleaning agent 22 By using the cleaning agent 22, the cleaning effect of the heated water 19 or of the water vapor, in particular if the cleaning agent 22 is matched to the substances to be expected, can be considerably improved.
  • control of the pump device 17 and the supply of energy to the heating means 20 can be effected by control and regulating devices, not shown separately here, which can also be provided in the functional unit 24.
  • the electrical energy required for this can also be generated by the drive unit, which is provided in the functional unit 24 and is not shown here, so that an electrical connection to the electrical system of the vehicle is not necessary, so that the aim of the invention of a simple additional structural unit without intervention in the design principles of the motor vehicle can be achieved, which in turn is of great advantage for maintenance, replacement and repair purposes.
