Definitions

  • the invention relates to a siphon well with a collecting container, which is provided on its lower part with a riser which merges into a vertical downpipe, to which a mainly U-shaped pipe connects, which is connected to a horizontal drain.
  • the device can be flowed through by both small, continuous amounts of liquid and intermittently flowing, larger amounts, the latter leaving the device in the form of liquid plugs with high kinetic energy.
  • Such liquid plugs can be deliberately aimed at to blockages, for example in drain pipes of houses and. To avoid where the line would not be self-cleaning otherwise with a free drain.
  • Another area where liquid conduction transport in plug form is desired is artificial irrigation when drainage pipes are connected to a lifting station.
  • the amount of liquid carried in such a system is somewhat more than 200 liters per person per 24 hours. This amount makes up 40 liters of flushing water from lavatories, through which the largest quantities of settable waste are introduced into the discharge pipe. A large part of the water reaches the drain pipe with a low volume flow, while the waste water from the lavatories is produced intermittently when the toilet is flushed.
  • drain pipes The general rule for drain pipes is that they must be dimensioned so that the greatest amount of water can be directed and that the pipe is self-cleaning. So far, the self-cleaning ability was mostly dependent on the required water speed.
  • a water speed of 0.6 m / s was specified as a need for self-cleaning.
  • the duration of the flow at this speed differs from country to country. Common in many countries, however, is that the water speed is considered to be independent of the line size and that the water speed means the maximum speed during a minimum day; more specifically, the rate of flow during the maximum hour of the minimum day.
  • the minimum day is the day of the year on which the drain pipe has the lowest flow load.
  • the quietest hour is the hour when the inflow from drain units other than the toilet is greatest.
  • the design flow is that which occurs when the number of holes in the toilet connected to the drain line in question is flushed during the maximum hour. This calculation was based on the Swedish authorities' approval that toilets may be flushed with 6 liters of water.
  • the transport takes place partly in that lumps flow with the water, possibly when the pipe bottom and the pipe walls touch. If the water storm is interrupted, the lumps sink to the bottom or they lie against the pipe sides. The next time the water is rinsed, they are raised and flow along a little, or if the amount of water is too low, they remain in the same place, whereby new, organic lumps can be deposited on them. Such increasing deposition can gradually lead to total constipation.
  • a double siphon well in which a riser pipe is arranged in a collecting tank, which merges into a vertical down pipe via a bend. At the highest point of the elbow there is a vent pipe which extends beyond the liquid level in the tank and which forms a water seal. When the water level in the tank rises, the air in the vent pipe is compressed and the water is expelled from the water seal, thereby clearing the way for the water in the tank through the double lifter.
  • This known device is structurally very complex because of the double U-shaped vent pipe.
  • the present invention serves the purpose of representing a device from which liquid in the form of stoppers with large kinetic energy can originate.
  • Two areas of application have been indicated above, namely, partly to improve the self-cleaning ability of drain pipes, which can be carried out with smaller dimensions than others due to the kinetic energy of the water plugs and partly to achieve longer transport distances through seepage pipes, due to the fact that the cohesive water plug due to its kinetic energy travels a relatively long distance while the plug gradually decreases in volume by releasing part of its liquid through the perforations along the conduit wall.
  • this is achieved in that the collecting container is connected to the riser pipe by means of a pipe elbow projecting downward from its bottom, and in that the U-shaped pipe merges into the horizontal drain in such a way that a normal one Liquid closure not completely closing the water inflow occurs, but that with higher water inflow the liquid closure in the tube closes and causes the siphon well to start.
  • the lower part 3 of the container runs a pipe 5 running with a selected slope to a summit point 4.
  • At the end of the riser 5 there is a bend 6, from which a vertical down pipe 7 is guided.
  • a dimension change can take place between elbow 6 and downpipe 7. This change is normally carried out as a taper 8, whereby the speed of the liquid can be changed.
  • the downpipe 7 is connected to a partially U-shaped pipe 9 with a horizontal outlet 10.
  • the drain 10 is connected to a municipal sewage system, or in the case of artificial irrigation, to an outgoing seepage gallery.
  • the summit point 4 of the riser 5 is chosen so that it comes to lie at the same height as the lid of the container 2.
  • a quantity of liquid flows via the summit 4 of the riser 5, which normally corresponds to the inflow present at the container 2. If this inflow is small, only a smaller amount of liquid per unit time flows through the downpipe 7 and down to the U-shaped pipe 9, which does not completely close the water seal. Since the entire course takes place at atmospheric pressure, the outflow coming from the pipe 9 becomes the same as large as the inflow in the feed line 1.
  • the variant of the invention shown in FIG. 1 cannot be used in vacuum systems, but is primarily intended for those drainage systems that operate at atmospheric pressure.
  • it has an inlet line 11, which is connected to the upper part of a container 12, from the lower part 13 of which a riser pipe 15 runs upwards at a selected angle.
  • a pipe bend 16 At the end of the riser is a pipe bend 16, the inner radius of which represents the summit point 14 of the riser.
  • a vertical downpipe 17 runs from the pipe elbow 16 via a taper 18 and is connected to a partially U-shaped pipe 19, the output side of which is connected horizontally to a drain line 20.
  • a vent line 21 is branched off from the outlet line 20 and is connected to the inlet line 11 of the device.
  • This vent line 21 has the effect that a water plug emanating from the pipe 19 does not have to work against a back pressure prevailing in the drain line 20. If there is a blockage in the further course of the drain line 20, which hinders a free flow of the air in the line, this air can be supplied via line 21 to the inlet line 11 and in this way via the ventilation lines normally occurring in the building the atmosphere can be derived.
  • the device has been described here mainly as a device for discharging waste water from a conventional drainage system.
  • the riser 5 By appropriate design and dimensioning of the riser 5, it can be easily adapted to drain systems that work with negative pressure. It can also be tuned as a metering device in manufacturing processes where batchwise supply of mixed material in the liquid phase is desired and where volume fluctuations in the order of magnitude of ⁇ 10% are acceptable.
