Definitions

  • the present invention relates to a device for regulating the flow rate of wastewater mixed with clear rainwater, transmitted to a purification station during floods and / or following a storm, comprising a collecting chamber equipped with a first orifice receiver of said mixed water, a second water-pouring orifice containing a high proportion of waste water, and a third water-pouring orifice containing a high proportion of clear water, said collecting chamber containing a weir a predetermined quantity of mixed water highly concentrated in waste water towards said second port, and for discharging the surplus of mixed water containing a high proportion of clear water into the collecting chamber and towards said third port.
  • each device according to the invention is relatively expensive to manufacture.
  • each device according to the invention is adapted to a pipe format, so that it is necessary to have a relatively wide range of "flood weirs" corresponding respectively to all the formats of existing pipes.
  • the present invention proposes to overcome these drawbacks by providing a device in which the central tubular element is designed in a simple and economical manner, which can be produced in large series.
  • this device comprises an adapter-reducer which makes it possible to adapt the same device "spillway of floods" to another format of existing pipes.
  • this adapter which can be produced so as to have several different degrees of reduction, a single type of "flood weir" can be connected to pipes of different calibers, depending on the reduction gear chosen.
  • the device according to the invention is characterized in that the weir is made in one piece from a tubular element connected between the first orifice and the second orifice, this element comprising a first zone of baffles arranged to follow the running an S-shaped path and a second clear water separation zone, comprising a waste water discharge channel formed in the last curve of the S in the direction of water circulation, and a profiled discharge fin provided with guide grooves, which originate in the last convex curve of the S to prevent the formation of a plug, and in that it comprises an adapter-reducing member composed of a frustoconical tubular section, the small diameter of which corresponds to the diameter inlet of the spillway and whose large diameter corresponds to the diameter of the mixed water supply pipe, this member comprising an overflow connected to the upper wall of the truncated tubular section having sex and being in communication with him.
  • the central opening 16 of the fixing plate 12 corresponds to the internal diameter of a supply pipe, to which it is planned to connect the described regulation device.
  • the central opening 17 of the fixing flange 13 corresponds to the inlet diameter of the weir, shown in more detail with reference to FIG. 4.
  • This water which contains a significant proportion of clear water, is discharged into the collecting chamber where it joins the water discharged by the crest of the weir and by the fin, to flow finally by the third orifice of the collecting chamber, connected to a pipe having substantially the same diameter as the inlet pipe.
  • the view in fig. 3 shows a variant according to which a window 18 has been formed in one of the side walls of the overflow 14.
  • This window is equipped with a grid 19 made up of flaps slightly inclined with respect to the direction of circulation of the water through the device (shown in fig. A).
  • This window is designed to communicate with a pipe 20, shown diagrammatically in FIG. 4, intended to channel a counter-current creating turbulence in the zone 21, with the aim of remove any waste likely to settle there.
  • Fig. 4 shows the flood weir constituted by a single piece 22 slightly bent, molded in a hard synthetic material, for example in polymerizable resin.
  • Interior bosses 23, 24 and 25 define an S-shaped channel illustrated by the arrows B, 8 1 and B 2 , which brings the water containing a high proportion of waste water to the second orifice of the collecting chamber (not shown).
  • two fixing flanges 27 and 28 On either side of the tubular weir are mounted two fixing flanges 27 and 28, which allow respectively to fix the weir to the flange 17 of the adapter-reducing member and to the pipe which leads to the second orifice of the collecting chamber .
  • the actual spillway, shown in fig. 4, and the adapter-reducing member of FIGS. 1 to 3, are preferably mounted one after the other inside the collecting chamber.
  • the flood weir which requires the construction of a mold, can be produced in relatively large series and combined with different adapters, themselves associated with the inlet walls of the collecting chamber having openings for different entry.
  • the overflow is calculated in such a way that all the water entering through the intake orifice is evacuated either through the overflow or through the overflow.
  • the channel 14 is therefore dimensioned so as to be able to evacuate at least the difference in the maximum quantities of water, which can be respectively absorbed by the supply pipe and the weir.
  • the overflow spill fin preferably comprises a set of guide grooves, making it possible to channel the waste present in the mixed water by giving the whole a smooth and progressive profile, without sharp angles.
