Description

Technical area

The present invention relates to a liquid distribution and distribution device intended in particular for distributing an effluent sparingly loaded with suspended matter and / or particles, in particular on a filtering surface. Said invention finds an application mainly in the field of non-collective sanitation, in the supply of so-called sand filters, compact filters, trenches or spreading beds, underground irrigation devices, or even so-called treatment devices primary, secondary or tertiary.

Previous state of the art

To supply a distribution network of wastewater treated by gravity or by flushing or even by pumping, the distribution devices range from a simple gravity flow, to the metering station connected to a low pressure network, to boxes with flush connected to a slotted network, or their combination through more sophisticated devices.

Most of the hydraulic models used, including the most recent ones, are based on very old concepts, for example:

- a distribution box fed by a gravity network and redistributing the effluent in several directions, in particular in a network with simple or so-called V-shaped slits, with the consequence of a non-homogeneous distribution and over a small percentage of the linear supply of said devices ,

- a large-volume float flush, associated with a simple distribution manhole and a 100 mm PVC network with slits at the origin, in particular of local overloads, for example on a sand filter,

- a trough box, with simple outlets and supplying the same type of slotted network, systematically resulting in non-homogeneous distribution,

- a low pressure supply from a mesh network, of small diameter, with small openings sensitive to clogging.

Neighboring patents illustrate this diversity of approaches and their limits: EP2404002 CA 2754640, US 4838731, US 1805862, US 1644532, US 931481 and US 710209, US 91828, US 3843976, WO 2008064420.

In a recent patent EP2404002 and patent application FR30492509, the improvement sought for a main application in the distribution of pretreated wastewater is only focused on a form of modularity of the bucket distribution box without taking into account the importance of the limits of simple slotted networks for homogeneous or balanced distribution in trenches, or on filter surfaces or other non-collective sanitation applications.

Other relatively recent solutions also ignore the need to review the distribution box concept, hunting upstream of a distribution network for certain applications in particular in non-collective, individual or group sanitation.

Detailed description of the invention

Other objects and characteristics of the invention will become apparent during the description which follows with reference to the appended drawings which are given by way of non-limiting examples and will make it clear what the invention consists of and how it can be implemented. .

In the accompanying drawings, for the figures numbered 1 to 3:

For FIG. 1, the general simplified diagram in plan, brings together the various components of the distribution and distribution device, the sequential supply internal to the box 30 or external, the two chambers 40 and 50, the partitioned outputs 60 and the network. partitioned 70 also,

For FIG. 2, it represents a simple bucket 20, said tip at the top 22, an axis positioning 24 and an adjustment counterweight 25,

For FIG. 3, 3a, 3b, 3c, this is a detailed presentation of the box 41, with a simple bucket in the low position because of its position only above the collection chamber and its orientation. hunting towards the entrances of the second chamber 51 and of the network intended for an application for the supply of a sand filter virtually cut into two blocks, said FIG. 3 showing essential accessories 52 roof, 53 corridor, 60 double outlet, 61 nesting ...

For FIG. 4, FIG. 4a represents in plan the organization of the distribution network by partitioned, full 72 or split 75a and 75b pipes, elbows 73, half-partitions in FIG. 4b with ventilation opening, for the choice of right and left flows and a loop 78 and FIG. 4b which shows the role of the partitions for supplying the two parts or blocks 81, 82, of the sand filter.

A detailed description of figures of the plates 1/3 to 3/3 makes it possible to present operating modes of different variants of the distribution and distribution device, in particular for the model intended for the traditional French sand filter, arranged downstream of a septic tank.

As illustrated in Figure 1, the general innovative concept is presented by a schematic plan view:

the supply is either external thanks to the use of the so-called pendulum or float flush 20b or thanks to a pump 20c, the effluent being transferred by a pipe to a collection chamber 40, or internal with a bucket presented in a position straddling the two chambers for flushing or emptying the bucket towards the external wall of the collection and distribution box 30.

The collection compartment 40 ensures balanced supply in the five pairs of lanes of the second compartment 50 with lanes, for a transfer of the effluent to the five double outlets, the connection means resume at the outlet of the box 30, the volumes transferred equivalents for supplying the final distribution network 70 with five double outputs supplying a network 70 with five lines, or even a single double output called open or active, supplying a network with a double line, with an additional distribution means 90.

As illustrated in FIG. 2, the bucket is said to be simple, with a pouring or flushing point situated in the high position 22, a reinforcement 23 comprising means for aligning the pivot axis 24, a trapezoid-shaped reservoir 21 and a counterweight 25, facilitating the return to equilibrium of the bucket after emptying triggered by the displacement of the center of gravity during the end feeding of said trough, passing from a filling phase to said emptying phase for a volume determined by the adjustments of the position of the axis and the counterweight.

As illustrated in Figure 3:

FIG. 3a represents a device configured for the use in feeding of a sand filter. The pretreated effluent passes either through a gravity feed in position A1 or A2 depending on the emptying mode of the bucket 21 chosen, 26b towards the wall 41 of the compartment 40 of the box 30 or towards the aisle entries 51 supplying the second compartment 50. In this configuration the edges of the bucket and its emptying are aligned on the two ends of the entrances of the second compartment, optimizing the distribution in equivalent volumes in each of the 10 lanes 53 with identical sections. The roof 52 closes the corridors to prevent any overflow during the transit of the effluent in the lower part of the chamber 50.

FIG. 3b is a schematic transverse view to illustrate the position of a trough 21 in a position above the corridors and the location of a supply A1, as well as the central outlet and the pairs of lateral outlets

60.

FIG. 3c shows in a plan section that there is continuity of flows in pairs of lanes, outlets 60 and inlet of the final distribution network 70, thanks to an interlocking 61.

Figure 3d shows in a cross section that the pair of lanes 54 at the outlet of the box is aligned to facilitate the entry of the effluent into the partitioned network 63, with in addition a threshold effect 62 to facilitate flow and hold account of a different length of the final distribution lines.

As illustrated in Figure 4:

FIG. 4a represents a sand filter 80 divided into two blocks 81, 82, joined one after the other with a supply by double network defining two watersheds, supplied independently. The effluent leaving the collection and distribution box imprints at least one line of the partitioned network. Each of these lines 71 has a first effluent transit section, full partitioned pipe 72, followed by at least one also partitioned elbow 73. The second section brings together a first network, partitioned pipe 75a which discharges the effluent by slit on one side by supply to the first sand filter block 81, via slits, the half-partition 76a serving as point of separation of the flow, the second part of the network on the other side ensures the supply of the second sand filter block 82, the half-partition 76b ensuring the second flow stop, while retaining a high ventilation 77c. After at least one bend, the third section of each line, without a slot 72, allows the effluent to reach a looping and ventilation look 78.

FIG. 4b, seen in cross section, shows that the partition 77b secured to a sleeve 77 is ventilated in the upper part 77c, said sleeve itself secured to a cradle 77a facilitating the maintenance of the verticality of the partition at the time of laying the network.

The operation of the power supply of a conventional sand filter can thus be summarized as follows:

- arrival of the effluent leaving, for example, a septic tank in the bucket integrated into the box 30,

- filling the bucket until a balance volume is exceeded,

- switching and feeding of 10 lanes then transit to the 5 double exits,

- first discharge into the double network up to the slots and uniform drainage on the filter by a series of unilateral slots,

- continuity of ventilation between the box 30, the network 70 and the loopback box 78.

The advantages of the invention therefore appear clearly for the supply of a traditional sand filter, its supply in two blocks by five lines with unilateral slits and the possibility of adapting to the evolution of these filters towards more units. narrow requiring a fewer number of supply lines 2 or 3 of these said lines.

Note that the partitioning and grouping of corridors can go from 2 to 3 or more compartments, and that the additional means of distribution at the end of the line are possible for use in spreading, irrigation, surface rejection and other supplies.

The advantages of the invention are therefore linked, beyond its hydraulic efficiency, to the existence of these variants, partly presented, facilitating its use in particular to adapt to the specific features of the new filters and new rejection methods or reuse of treated effluents.

All modifications in accordance with the basic concept, object of the innovation, must be included as defined in the claims.
