Definitions

  • the invention relates to a lifting gully arrangement according to the preamble of claim 1.
  • Lift gullies are used, for example, in the street inlets of shafts with mixed and waste water collectors that often have poor flow.
  • water collectors tend to deposit solids, which usually have to be cleaned at regular intervals using high-pressure flushing devices. In many cases, such cleaning is necessary on a monthly basis in order to avoid clogging of the sewage system or to always ensure the maximum possible discharge amount when a rain event occurs.
  • lifters are installed in the street inlets, which thanks to their training periodically, i.e. If a certain amount of water accumulates, empty the shaft or container within a very short time. Due to the strong suction effect of the lifter in operation, solids deposited on the bottom (sump) of the manhole are entrained on the one hand and deposits in the sewerage pipes leading away from the manhole are also detached from the pipelines by the relatively strong water surge swept away.
  • a lifting gully arrangement is known from Swiss patent specification 676264, in which both the hairpin-shaped lifting tube and the odor trap (siphon) are arranged within the shaft and the odor trap can be cleaned by lifting off a cover.
  • the object of the present invention is to provide a lifting gully arrangement which, on the one hand, can be connected to the sewer system as a ready-made unit and, on the other hand, ensures optimum accessibility for its cleaning.
  • Another object of the invention is to arrange the throttled spout when using the lifting gully arrangement in separation systems in such a way that it is inexpensive to manufacture, reliable and easy to clean.
  • the first task is solved by a lifting gully arrangement according to the features of claim 1.
  • the second task is solved by the features of claim 6.
  • the suction side leg can be lifted out of the container without tools before cleaning the sump.
  • this can be pulled out of the plug connection; in the case of a tubular design, the leg on the lifter side can be raised without the leg on the suction side having to be released from the connecting line to the sewage system.
  • a device or a weight arranged at the end of the tubular part ensures that the suction-side end cannot be lifted from the bottom of the shaft even if the lifting tube is empty.
  • the funnel-shaped extension at the suction-side end of the lifting tube which is placed over a truncated cone-shaped elevation on or in the bottom of the container or a cone is inserted in the tube end, enables the suction of solids deposited on the bottom with high suction speed, since the ring cross-section between the suction-side End of the lifter and the frustoconical elevation is formed less than or equal to the cross section of the lifter tube. At the same time, the risk of constipation can be significantly reduced.
  • a throttle element in short a throttle, for example a vortex throttle, in the knee between the vertical overflow pipe and the horizontal drain pipe enables a continuous outflow of the inflowing water into the channel in separation systems, regardless of the gully filling.
  • the vortex throttle located inside the lift gully like the lift tube itself, can be installed at the factory and is easy to clean. If there is a large inflow of water and the permissible amount of water is exceeded, e.g. during a heavy rain event, the solid section floating in the tank is held up by the pipe section attached to the upper end of the overflow pipe and protrudes from the latter and is fed to the sewer system after the rain event.
  • the lifting gully arrangements 1 in FIGS. 1 to 4 are installed in a container or shaft, container 3 for short.
  • the design of the upper inlet is not shown in the figures; it can be made from a slotted cast lid 5 with or without a conventional type of sludge bucket.
  • a hairpin-shaped lifter 7 made of steel or plastic is shown, the inlet-side tube 8 of which is inserted with the end 9 in a plug-in closure 11 and connected to a sewage system or a sewage pipe 15 by a connecting line 13.
  • An odor trap or siphon 17 can be installed in the connecting line 13.
  • the suction-side tube 18 with the end 19 of the lifter 7 can have a funnel-shaped section 21, to which a cone or frustoconical part 23 is fastened to form a conical ring-shaped space 25.
  • the frustoconical part 23 can also be placed on the bottom 27 of the container.
  • the suction-side end 19 of the lifting tube 7 preferably projects into a depression or a sump 29 in the base 27.
  • a handle 31 is fastened, which serves to pull the tube 8 out of the plug closure 11 and to remove it from the container 3.
  • the lifting gully arrangement 1 is connected to a so-called separation system, two drains are provided for additional separation of contaminants.
  • the drain from the lifter 7 can lead to the wastewater treatment plant; the second drain can be in a body of water.
  • the second drain has an outlet throttle 33 on the inlet side in the container 3, through which the water can be fed directly to a channel 35 in the case of small to medium inflows, without the lifter 7 starting.
  • An overflow pipe 37 leads from the discharge throttle 33 to close to the upper end of the container 3.
  • a pipe section 39 is placed on the upper end, the inside diameter of which is larger than the outside diameter of the Overflow pipe 37 and its upper edge 41 is above the upper edge of the overflow pipe 37.
  • the throttle 33 consists of a vortex throttle which is placed on the knee between the overflow pipe 37 and the outlet pipe 43.
  • the throttle 33 can be firmly connected to the drain pipe 43 or screwed to the latter for cleaning or repair purposes.
  • the lifter 7 consists at least partially of an elastic hose 45, the inlet-side end 9 of which is connected to the connecting line 13 projecting into the container 3 in this embodiment.
  • a device or a weight 47 is attached to the suction-side end 19, the mass of which cancels the buoyancy of the empty lifting tube 7 in the filled container 3, so that the suction-side end 19 of the hose 45 is pulled down into the region of the bottom 27.
  • a closable cleaning connector 49 is attached in the connecting line 13 and forms an access to the siphon 17.
  • a handle 31 reaching to the suction-side end 19 and connected there with hose 45 allows the operating personnel to carry out the Lift hose 45 out of container 3 to clean it. For exact positioning of the hose 45 and its suction-side end 19, this can be suspended from a hose support 51.
  • a vertically arranged outlet throttle 33 is shown, which is placed on the inner end of the drain pipe 43.
  • the flexible lifting tube 7 is even closer to the wall of the container 3.
  • the overflow tube 37 is arranged on the opposite side and the drain pipe 43 leaves the container 3 on the opposite side of the connecting line 13.
  • the embodiments of the lifting gully arrangement 1 shown in FIGS. 1 to 4 can all be carried out without the overflow pipe 37 and the drain pipe 43 if all the water flowing into the arrangement 1 is to be fed through the lifter 7 to a sewage / sewage system.
  • the water can be fed to the lifting gully arrangement 1 through the upper opening of the container 3 or through the side into the container 3 or another, also higher, feed.
