Definitions

  • the invention relates to a vacuum toilet with a toilet bowl, a vacuum generator, a collecting container, lines with valves and an intermediate container with an inlet and an outlet valve arranged between the toilet bowl and the collecting container, as well as a method for operating such a vacuum toilet.
  • a so-called vacuum toilet system and the operation of such a system is described, for example, in DE 37 28 157 A1.
  • the system disclosed there is intended 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 an intermediate container arranged between the toilet bowl and the collecting container.
  • the procedure is as follows: With the device for generating a vacuum, which can be an ejector connected to a compressed air tank, a negative pressure is generated in the intermediate tank.
  • a valve which can be opened pneumatically, is provided in front of and behind the intermediate container. After pressing a flush button, a negative pressure is generated in the intermediate container and flushing water enters the toilet bowl.
  • the valve arranged in front of the intermediate container is open, flushing water and faeces are sucked into the intermediate container from the toilet bowl, which is under atmospheric pressure, as a result of the pressure gradient.
  • the intermediate container is pressurized and, after opening the valve downstream of the intermediate container, the Contents of the intermediate container emptied into the collecting container.
  • the wastewater is also located in the intermediate tank and, if the inlet and outlet valve seals are leaky or worn, is also pressed into the valve housings, which can lead to deposits and, after a certain period of time, to valve failure. Furthermore, it can happen that while one of the valves is opening, the housing space is briefly released and the waste water gets into the housing at the same time.
  • the aim of the present invention is to prevent this penetration of waste water into the housing of the valves and this is achieved in a vacuum toilet of the type mentioned in that the housings of the inlet valve and the outlet valve are each connected to one or one source of pressure medium that the pressure in the housings is higher than that in the intermediate container when the pressure for conveying the drainage mass into the collecting container is built up there.
  • the pressure medium source can also be connected to the sides of the valves facing away from the intermediate container.
  • 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 an intermediate container arranged between the toilet bowl and collecting container with an inlet and an outlet valve, the inlet valve housing and the outlet valve housing below higher pressure than that of the intermediate container is maintained when this pressure is built up. It is obvious with the embodiment according to the invention that no deposits can form in the valve housings, which leads to an increase in the service life of the valves.
  • the single figure of the drawing shows part of a vacuum toilet according to the invention.
  • 10 denotes the intermediate container, which is located in terms of flow between a basin 19 and the sewer line or a collecting container 20.
  • This intermediate container 10 is closed on both sides by valves, namely by the inlet valve 11 and the outlet valve 12. These are slide valves or hose valves.
  • the housings of the two valves 11 and 12 are shown connected to a compressed air line and the addition P 9 is intended to express that a pressure is applied here that is higher than that in the intermediate container 10 when a pressure is built up there to convey the drainage mass will.
  • compressed air P 9 is simultaneously applied to the housings of the valves 11 and 12, so that "clean" compressed air from the valves reaches the intermediate container 10 so that no drainage material can collect there and the valves remain “clean” and ultimately the life of the valves and the entire system is increased.
  • the required pressure P 9 can also be derived from the pressure P which is effective in the intermediate container 10.
