Definitions

  • the invention relates to a vacuum toilet with a toilet bowl, a vacuum generator, a collecting container, lines with valves and arranged between the toilet bowl and reservoir intermediate container with an inlet and an outlet valve and a method for operating such a vacuum toilet.
  • a so-called vacuum toilet system and the operation of such a system is for example in the DE 37 28 157 A1 described.
  • the system disclosed therein is to be used in particular in mobile units, such as trains and buses.
  • the following components belong to the system described there: A toilet bowl, a device for generating a vacuum, a collecting container, lines with valves and arranged between the toilet bowl and collecting container intermediate container.
  • the procedure is as follows: With the device for generating a vacuum, which may be a connected to a compressed air tank ejector, a negative pressure is generated in the intermediate container. Before and behind the intermediate container a valve is provided in each case, which can be opened pneumatically. After pressing a flush button, a vacuum is generated in the intermediate tank and rinse water enters the toilet bowl. With the valve arranged in front of the intermediate container, rinsing water and faeces are sucked into the intermediate container as a result of the pressure gradient from the toilet bowl, which is under atmospheric pressure. Thereafter, with closed valves, the intermediate container is pressurized and after opening the intermediate container downstream valve is the Contents of the intermediate container emptied into the collecting container.
  • the waste water When pressure is built up in the intermediate container, the waste water is also in the intermediate container and is pressed in leaking or worn seals of the inlet and outlet valves in the housing of the valves, which can lead to deposits and after a certain period of failure of the valves. Furthermore, it may happen that while one of the valves is opening, at the same time the housing space is briefly released and the wastewater enters the housing.
  • the housings of the inlet valve and the outlet valve are connected either to one or in each case with a pressure medium source and that the pressure in the housings is higher than that in the intermediate container, when there the pressure for conveying the drainage mass is built up in the collecting container.
  • the pressure medium source may be connected to the intermediate container remote from the sides of the valves.
  • the invention also relates to a method for operating a vacuum toilet with a toilet bowl, a vacuum generator, a collecting container, lines with valves and arranged between the toilet bowl and reservoir intermediate container with an inlet and an outlet valve, wherein the inlet valve housing and the Auslrawventilgephaseuse below be held higher pressure than that of the intermediate container when built in this pressure.
  • 10 designates the intermediate container, which is fluidly located between a basin 19 and the sewer pipe or a collecting container 20.
  • This intermediate container 10 is closed on both sides by valves, through the inlet valve 11 and the outlet valve 12. These are slide valves or hose valves.
  • the housing of the two valves 11 and 12 are shown connected to a compressed air line and by the addition P g is to be expressed that here a pressure is applied which is higher than that in the intermediate container 10, if there built a pressure for conveying the drainage mass becomes.
  • the required pressure P g can also be derived from the pressure P, which is effective in the intermediate container 10.
