Definitions

  • the invention relates to a sludge suction vehicle, the sludge receptacle with a sludge supply nozzle, a water pump connection, which leads via filter devices to a supply of a high-pressure flushing device, and in the area of the water pump connection with a coarse filter for separating solids and water.
  • the object of the present invention is therefore to create a sludge suction vehicle of the type mentioned in the introduction, in which a much better separation between water and solids takes place in the sludge tank.
  • a chain curtain is used as a coarse filter within the sludge compartment Det, which extends substantially over the entire cross-section of the container.
  • the chain curtain can be formed from a plurality of chain strands which are not connected to one another and are arranged closely adjacent to one another, the upper ends of which are firmly connected to the container wall.
  • a chain curtain can act differently in points because the individual links of the chain curtain can perform a movement that is different from the movement of the neighboring links.
  • the solids of the sludge supplied on the inlet side can lose their kinetic energy much better and then sink downward on the inflow-side surface of the chain curtain due to gravity. The water emerging behind the chain curtain is then much better cleaned.
  • An improvement in the effect of the chain curtain can also be achieved by arranging a pendulum-suspended baffle from the flow side behind the chain curtain, which extends essentially over the entire lower half of the container parallel to the chain curtain.
  • the mud suction vehicle shown in the drawings consists of a kettle-like sludge receptacle 11 carried by the vehicle chassis 10, which can be closed at its rear end with a dome-like cover 12.
  • a water pump connection 13 In the cover 12 there is a water pump connection 13, via a filter arrangement (not shown) to a process water compartment of the container 11 or a separate process water storage tank.
  • a hinge joint 14 Between . the container 11 and the lid 12 is a hinge joint 14, which gives the possibility of pivoting the lid 12 upward about a horizontal axis for emptying the container 11.
  • the container 11 is provided with a sludge feed pipe 15, which has a hose, not shown can be connected to a drain or the like to be emptied.
  • a solid return line 16 which is connected to the filter arrangement located between the sludge tank and the service water tank, projects through the tank 11 from bottom to top. If, during operation, the sludge S has been deposited on the bottom of the container, water which can be used for further high-pressure flushing can be pumped out above the solids via the nozzle 13.
  • a chain curtain 18 is provided in the container 11 so that relatively well pre-cleaned water is obtained at the nozzle 13 above the deposited sludge S.
  • This chain curtain consists of a plurality of interconnected, closely adjacent chain strands, the upper ends of which are firmly connected to the wall of the container 11, but preferably via an arcuate holder 17 to the cover 12.
  • the chain links are made of metal and in practice a chain link size of approximately 5 to 10 cm has proven to be useful.
  • a baffle 20 is arranged at a distance, which is formed by a semicircular sheet can be, which extends substantially over the entire lower half of the container cross-section.
  • the bearing axis 21 arranged at the upper edge of the baffle wall is preferably fastened to the cover 12 with a holder 19, although it can of course also be stored in the container 11 itself.
  • the baffle 20 ensures that the water to be reused from the muddy material is only passed on from the upper half of the chain curtain 18, where it contains less solids and that the soil sludge is kept away from the water pump nozzle.
  • An even further improved cleaning effect i. H.
  • An improved separation of solids and water is achieved if a coarse sieve in the form of a perforated plate 22 is arranged in the cover 12 behind the baffle 20, preferably at a distance of 3 mm.
