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 connectable 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.
  • Municipal vehicles of this type have been known for a long time (DE-OS 31 40 200) and are usually used for cleaning and flushing sewer pipes, the dirt being sucked out of the sewer pipes by means of the vehicle and transported away.
  • the drained off dirty water is used to reduce the water requirement of such vehicles, if necessary after pre-cleaning inside the vehicle, used again to rinse the channel or the like.
  • Municipal vehicles of this type are often used in connection with the cleaning and flushing of channels and containers that also contain oil-containing substances.
  • cleaning in the above-described sense with cold water in the service water compartment of the container of the municipal vehicle is not only very limited but also impossible, although it should be emphasized that cleaning tools, suction hoses, sieve covers and the like is also possible if not expressly so have come into contact with oily substances, are often very difficult and cannot be carried out with sufficient success.
  • the object is achieved according to the invention in that 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.
  • 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 above-described sense , 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 formed by a heat exchanger which interacts with the cooling water circuit of a drive unit of the vehicle, this embodiment in particular representing a very inexpensive solution to the tasks according to the invention, especially since the vehicle drive is active when the municipal vehicle is operated as intended.
  • the Heat exchangers also interact with the exhaust system of the drive of the municipal vehicle.
  • Another advantageous embodiment of the vehicle in which it is possible to operate the actual cleaning process independently of the drive unit of the vehicle, is advantageously created in that the energy required by the heating means is provided by an energy source separate from the motor vehicle.
  • 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 can be advantageous to drive the pump device electrically, for example from the on-board electrical system of the municipal vehicle.
  • the pump device hydraulically and / or mechanically, ie either directly from the drive unit of the motor vehicle or by a separate one drive unit to be provided, which in turn can be driven with 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 allows, for example, the use of prefabricated or pre-assembled functional units as are known per se in the trade. Such functional units also allow very quick assembly and disassembly for maintenance purposes, and an exchange of the entire functional unit for maintenance and repair purposes and to ensure the operational readiness of the municipal vehicle is easily possible by installing a completely different functional unit.
  • 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 can be used in this regard, so that such an embodiment also is cheaper than a solution that is fully integrated into the vehicle and is 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.
  • DE-OS 31 40 200 With regard to the general structure of such a municipal vehicle and its mode of operation, reference is generally made to DE-OS 31 40 200.
  • the municipal vehicle in addition to the discharge of cold water or water 19 at ambient temperature via the line / delivery connection 13 to the flushing hose 14, effected by the pump device 15, the municipal vehicle has a second line / delivery connection 23, which also flows into the process water section 12 of the Container 10 opens.
  • 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 towards 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.
  • the heating means 20 may also be sensible to obtain the energy supplied to the heating means 20 via heat exchangers which interact with the coolant circuit of the drive unit of the vehicle and / or the exhaust system of the drive unit of the vehicle. 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.
