Definitions

  • the present invention relates to a device for distributing effluent from a septic tank to a number of pipes supplying the effluent to a filter bed.
  • the device comprises a distribution box having a bottom, a front wall, a rear wall, two side walls and an inlet to allow said effluent to enter the distribution box. It also comprises a rocker mounted in said distribution box to pivot around a pivot axis which is substantially parallel to said front wall.
  • the rocker is located below said inlet to receive effluent flowing into the box and is configured to be in an equilibrium position when filled with effluent to a predetermined level and then rotates automatically because of the weight of the effluent contained therein to evacuate the effluent contained in the rocker into the distribution box.
  • the distribution box has an upper part provided with said inlet and a lower part which is provided with a plurality of outlet openings.
  • the lower part is narrower in cross-section perpendicular to said pivot axis than the upper part.
  • the front wall of the upper part forms a ramp which has a lower edge which is located at the transition between the upper part and the lower part and which is substantially parallel to said pivot axis. The ramp is configured to receive the effluent which is evacuated from the rocker and to direct this effluent towards the rear wall of the distribution box.
  • Such a device for distributing effluent from a septic tank to a number of pipes supplying the effluent to a filter bed is already described in the document FR-B-2 953 868 .
  • the device collects a quantity of effluent in the tipper and discharges it discontinuously, so that a relatively large quantity of water is discharged into the pipes each time. In this way, a more uniform distribution of the effluents on the different pipes can be obtained.
  • the distribution tank is also equipped with a ramp on which the effluent contained in the tipper is evacuated. The ramp is located opposite the outlet openings so that effluent flow is directed through the ramp to the outlet openings. Due to the velocity of the effluent reached during the descent of the ramp, the effluent will flow a longer distance in each of the pipes connected to the outlet openings.
  • a disadvantage of the prior art device is that outlet openings can only be provided in the rear wall of the distribution box, so that the distribution box has to be located on one side of the filter bed. As a result, the pipes feeding the side areas of the filter bed are longer and must contain curved connecting pieces. Therefore, less effluent will flow in these laterals and/or effluent in these laterals will flow less far.
  • the filter bed does not have to be quite elongated but can be squarer and therefore more compact.
  • Such a position of the box distribution requires that the outlet openings be provided on opposite sides of the box.
  • outlet openings are only provided in the rear wall, that is to say opposite the inlet opening.
  • the document DE 38 16 378 A discloses a device for distributing an effluent from a septic tank to several pipes supplying the effluent to a filter bed.
  • the document DE 3818714 A discloses a process for wet surface treatment of semiconductor chips.
  • the document US 2004/0134542 A describes a system configured to distribute a flow of liquid in predetermined proportions.
  • the system includes a dispenser defining a plurality of outlets configured to dispense liquid from the dispenser.
  • exit openings are provided not only in the rear wall but also in the two side walls.
  • partitions are provided on the bottom of the distribution box so that the effluent is equally divided over the different outlet openings.
  • this system does not allow still not to also provide openings in the front wall of the distribution box.
  • An object of the present invention is therefore to provide a new device for distributing effluent from a septic tank to several pipes supplying the effluent to a filter bed in which the outlet openings can be provided in the rear wall of the distribution box, or possibly also in its side walls, but in which a number of outlet openings can also be provided in the front wall of the distribution box while ensuring a sufficiently uniform distribution of the effluent on the different exit openings.
  • the device according to the present invention is characterized in that the ramp in the distribution box is configured in such a way that a plane containing said pivot axis and said lower edge forms an angle between 15° and 45° with a vertical plane containing said pivot axis and in that said plurality of exit openings comprises at least one exit opening in said front wall and at least one opening outlet in said rear wall.
  • outlet openings of the device according to the present invention are thus provided both in the front wall and in the rear wall of the distribution box. Such an arrangement of outlet openings allows a more compact layout of the waste water treatment system.
  • the ramp extends to a relatively low level, so that its lower edge is located vertically below the pivot axis approximately at the level of the centers of the exit openings. The effluent which flows through the ramp is therefore entirely directed towards the various outlet openings.
  • the ramp ends earlier, at a higher level, where the effluent continues to flow from the tipper.
  • the flow of effluent leaving the rocker is thus directed, at the level of the lower edge of the ramp, obliquely downwards and the front wall while the flow of effluent flowing along the ramp is directed towards the lower edge of the ramp obliquely downwards and the rear wall.
  • the two effluent flows compensate each other, so that there is substantially no preferential flow towards the front wall or towards the rear wall of the distribution box.
  • the quantity of effluent discharged by the various outlet openings can thus differ by less than 25%, preferably less than 15%, from the average quantity of effluent discharged through the various outlet openings.
  • the lower edge of said ramp is located above said outlet openings.
  • the angle formed between said plane which contains said pivot axis and said lower edge and said vertical plane is greater than 20°, preferably greater than 25° and more preferably substantially equal at 30°.
  • the angle formed between said plane which contains said pivot axis and said lower edge and said vertical plane is less than 40°, preferably less than 35° and more preferably substantially equal at 30°.
  • the length of the ramp can thus be chosen to obtain the same flow rate of effluent through the openings of the rear wall and of the front wall.
  • said ramp forms an arc around said pivot axis, said arc is preferably substantially an arc of a circle having said pivot axis as its central point.
  • the tipper can extend a greater distance towards the ramp, so it can have a larger volume while being configured to be emptied automatically by the effluent it contains once the maximum level is reached in the rocker.
  • said arc extends over an angle ( ⁇ ) around said pivot axis of at least 45°, preferably at least 50° and at most 55° and at most 75°, preferably at most 70°, more preferably at most 65°.
  • Such angles contribute to obtaining an even distribution of the effluent towards the front and rear wall of the distribution box.
  • a line tangent to said arc at the location of said lower edge forms an angle of at least 15°, preferably at least 20°, more preferably at least minus 25° with a horizontal plane.
  • a line tangent to said arc at the location of said lower edge forms an angle of at most 45°, preferably at most 35°, and more preferably at most 30° with a horizontal plane.
  • the inclination of the lower part of the ramp can thus be chosen to obtain the same flow rate of effluent through the openings of the rear wall and of the front wall.
  • said rocker has an edge on which the effluent is evacuated out of the rocker, said edge passing at a distance less than 30 mm, preferably less than 20 mm and more preferably less than 10 mm, measured in said cross section, from the lower edge of the ramp during pivoting to evacuate the effluent contained in the tipper.
  • Such a small distance between the edge of the rocker and the boom helps to provide a larger rocker, and therefore a higher capacity of the device, and also improves the interaction between the flow of effluent downstream of the boom and the flow. of effluent out of the tipper.
  • said rocker has an edge on which the effluent is evacuated from the rocker, which edge is located in said cross section at a predetermined distance from said pivot axis, the lower edge of said ramp being located at a height above the bottom of the distribution box, which height is greater than 50%, preferably greater than 60% and preferably greater than 65% of said predetermined distance.
  • Such a relatively large height of the lower part of the distribution box contributes to obtaining an even distribution of the effluent towards the outlet openings in the front and rear wall of the distribution box.
  • said rocker has an edge on which the effluent is evacuated from the rocker, which edge has a length greater than 70%, preferably greater than 75% and more preferably greater than 80 % of the internal length of the lower part of the distribution box, measured between the said two side walls.
  • the flow of effluent leaving the rocker is better distributed over the length of the distribution box or in other words over the various outlet openings in the wall. front and in the rear wall when several outlet openings are provided in the front wall and in the rear wall.
