Definitions

  • the invention relates to a mud suction vehicle according to the preamble of claim 1.
  • Such a mud suction vehicle is known from DE-PS 30 34 058.
  • water carried along with the vehicle for cleaning for example a sewer, is sprayed onto the object to be cleaned under high pressure, and is then sucked into a container of the sludge-suction vehicle with the sludge substances thereby detached.
  • the sucked-in water is separated from the substances it contains and fed back to the cleaning jet.
  • a discharge line in the container for discharging the water to be supplied with the cleaning jet is provided with a filter at one end which can be moved up and down with a buoyancy body in order to separate out the coarse particles present in the tank water. The sludge settles on the bottom of the tank.
  • the water can be drained from the tank with the least filtering effort, since there are no substances floating on the water surface in this area, and also the density of the substances that settle down with gravity at a certain height over the deposit layer is relatively low.
  • the buoyancy body In order to balance the weight of the discharge lines and the filter, the buoyancy body must be of a relatively large size, as a result of which space is lost for the sludge to be collected and for cleaning water.
  • the buoyancy body floating on the water surface can be of a significantly smaller shape, since the load of the suction line is mainly taken over by the springs and the buoyancy body only has a control effect.
  • the springs are biased against the gravity of the parts of the drain line, so that the buoyancy body only has to compensate for a small part of the gravity of the filter and the drain line.
  • the up and down movable, provided with the filter end of the drain pipe is automatically adjusted in height to the changing water surface as in the Tecnik state.
  • the buoyancy body formed as a rigid hollow body which is connected via a connection to a line led out of the tank. According to this embodiment, it can be checked via the line whether the buoyancy body has suffered damage and has become leaky, or the buoyancy body can be flooded by supplying water in order to lower the filter deeper into the sludge water in the case of substances floating on the water surface.
  • the buoyancy body consists of a gas-inflatable balloon made of a robust, flexible material, the volume of which can be adjusted depending on the gas filling and which cannot exceed a predetermined maximum volume.
  • a variable buoyancy can thus be obtained so that the filter can be held in different positions with respect to the water surface.
  • a plastic tarpaulin reinforced with textile, for example, is suitable as the material for such a balloon. Since the maximum volume is fixed, a predetermined maximum buoyancy force cannot be exceeded even with variable pressure, in particular with negative pressure in the container.
  • FIG. 1 and 2 show a container 1 in which sucked-in sludge water 2 collects and on the bottom of which sludge 3 is deposited.
  • a filter designed as a cage drum 26, through which the water to be discharged enters a discharge line present in a hollow support 16.
  • the discharge line consists of a further tube 11 inside the container, which is connected to a flange 10 of a lead-through tube 8 through a container wall.
  • the discharge line is provided with a valve 40 on the outside of the container. Between the valve 40 and a low-pressure suction pump 42 there is a flexible hose line 41.
  • the cage drum 26 is cylindrical in shape with rods arranged along the cylinder jacket and fastened to rings in the interior of the drum. At the front ends of the cage drum there are rings for attaching doctor blades.
  • a buoyancy body 31 and the cage drum 26, which acts as a coarse filter, are fitted between two carrier brackets 15 and 16.
  • the support brackets are in turn rotatably attached to the pipe 11 serving as part of the discharge line, the axis of the pipe 11 being perpendicular to the longitudinal direction of the two supports 15 and 16.
  • the tube 11 is firmly attached to the container wall by means of the tube bushing 8 and the flange 10 and a holding strut 9.
  • the two support points of the tube 11 are each located near the lateral ends of the tube.
  • the carrier 16 is designed as a hollow carrier and, together with the feed-through tube 8, the tube 11 and the cage drum 26, represents the discharge line which can be moved up and down at one end.
  • the cage drum 26 is rotatably mounted between the carriers 15 and 16, and also has Carrier 16 out a rotary flange through which the water entering through the cage drum can enter the hollow support 16.
  • the cage drum 26 rotating about its axis of rotation 27 is driven by a drive 28 attached to the carrier 15.
  • a stripper 25 is held between the tube 11 and the cage drum 26 between the two supports 15 and 16.
  • the scraper 25 rests on the cage drum 26 and, due to the rotational movement of the cage drum 26, wipes off coarse material lying on the outside of the filter drum.
  • the scraper 25 consists of a scraper bar the length of the cage drum 26, the scraper bar being held by three holding brackets which in turn are fastened to a holding rod which is rotatably held between the carriers 15 and 16 and lies parallel to the axis 27 of the cage drum 26.
  • the buoyancy body 31 is attached, which in the embodiment shown has the shape of a drum and is designed as a rigid hollow body.
  • the buoyancy body is connected to a line 34.
  • the line 34 is attached to a flange 35 which is formed on a bushing projecting through the container.
  • the drum-shaped buoyancy body is fastened to the carriers 15 and 16 via the buoyancy body brackets 32 and 33.
  • a container strut 6 is attached to the container 1 and has at its end a trailer buffer 7 on which a holding part rests in a lower end position.
  • a spiral spring 19 and 20 are attached to laterally outstanding fastening webs 17 and 18 on the supports 15 and 16, respectively. With their second end, the coil springs are each attached to the tank 1.
  • the two respective attachment points at the ends of the springs are at different heights, so that the springs are biased due to the load with the weight of the parts of the discharge line.
  • the floating body 31 floating on the water surface must therefore compensate for a smaller part of the weight of the parts of the discharge line which can be moved up and down.
  • the two support beams are angled in their central region.
  • the cage drum 26 is fastened in the downwardly angled region of the two supports 15 and 16. This ensures that the cage drum is completely immersed in the water if, at a water level, as shown in the drawing, the axis of the buoyant body 31 and the axis of rotation 12 of the holding brackets 15 and 16 have approximately the same height.
  • the brackets 15 and 16 could also be bent in the opposite direction, the same function being achieved if the positions of the cage drum and the buoyancy body are interchanged.
  • the buoyancy body 31 floating on the water surface 4 moves with the water level upwards or downwards, the two supports 15 and 16 moving about the axis of rotation 12 on the Turn tube 11.
  • the position of the cage drum 26 with respect to the water surface is moved according to the division ratio of its arrangement on the supports 15 and 16 between the buoyancy body and the axis of rotation 12.
  • the semitrailer 6 is present, which limits the downward movement of the carrier 15. A large part of the weight of the free end of the one-sided parts of the discharge line is absorbed by the two spiral springs 19 and 20.
  • a torsion bar spring is used for partially absorbing the weight of the discharge line.
  • the torsion bar is parallel and in the vicinity of the axis of rotation 12. While one end of the torsion bar is attached to the container 1, at another end of the torsion bar a support is attached at right angles, on which one of the supports is slidably supported with a sliding part.
  • the torsion bar can, for example, be held in a tube of suitable dimension attached to the container 1.
  • the non-deformable drum-shaped buoyancy body 31 is connected to a feed line 34, through which the buoyancy body 31 can be filled with water.
  • the weight of the buoyancy body 31 is thus increased, so that the buoyancy is no longer sufficient to keep the buoyancy body on the water surface.
  • This proves to be particularly useful or desirable when there is a thick layer of floating substances 5 on the water surface 4 floats, and the cage drum 26 is to be lowered below this layer of floating substances 5.
  • the feed line 34 proves to be advantageous since it can be determined via the line 34 whether the buoyancy body 31 is damaged within the rough operating conditions within of the container 1 is done. Damage to the buoyancy body 31 can easily be demonstrated, since in this case water emerges through the line 34.
  • a deformable body which can be filled with gas can also be used.
  • a balloon body for example made of a plastic material, is provided with a pressurized gas line and is filled with gas as required, whereby the balloon expands against the gravity of the water and creates an effective buoyancy body.
  • the expansion of the balloon and thus the buoyancy can be controlled by filling the balloon with gas. It can thus be achieved that the filter is held at different depths below the water surface 4, depending on the filling of the balloon with gas.
  • the filter When the balloon is completely filled, the filter is held very close to the water surface, when the balloon is filled mediumly in a middle area between the water surface and the deposited sludge layer 3, and when the balloon is filled slightly, the filter is located near the deposit layer 3 at the bottom of the container.
  • the tightness of the container can be checked via the gas pressure resistance of the system.
  • a buoyancy body as a hollow body, a buoyancy body as a solid body made of material of low specific density, such as Wood or polystyrene. With solid bodies, however, there is no possibility of influencing the buoyancy force or the weight of the arrangement and thus adjusting the position of the filter with respect to the water surface.
