Description

"Hunting and distribution device
liquid"
The present invention relates to a device for flushing and distributing liquid. More particularly the present invention relates to any field where it is.

necessary to send a determined quantity of liquid in spurts.

 In the field of wastewater treatment, for example using septic tanks, after treatment of the water, it is necessary to send it into a spreading system. In many cases this spreading system is produced by a network of perforated, buried pipes. When the treated water arrives in small quantities and. under a low flow we see that only the first meters of such a spreading system are used. In fact, water comes out of the pipes through their perforations and does not spread over the entire pipe. As a result, the spreading system is very poorly used and there are significant risks of scouring, hydraulic overload and clogging.

 In addition, this poor distribution of treated water causes local subsidence of the land in which the spreading system is located.

 It is known to use pumps requiring an electrical energy supply, to pump treated water from septic tanks to a spreading system. Similarly, the use of traditional siphoning flushes requires that the septic tank be buried deeply. In addition to the fact that a deeper excavation is always longer and more expensive to carry out, there is a risk by digging deeper of encountering soil levels unfavorable for purification and / or the water table.

 The object of the present invention is to alleviate all of these drawbacks by creating a device allowing optimal use of the spreading system and not requiring for its installation that the water treatment installations are buried more deeply. , or that an electrical power supply is planned.

 To this end, the present invention relates to a device for flushing and distributing liquid, characterized in that it comprises at least one trough collecting a liquid and at least one siphon, said trough and / or said siphon pivoting between a position of filling, in which the liquid. fills said bucket, and a drain position, said pivoting. causing the priming of said siphon and the sudden emptying of said trough.

 By virtue of these provisions, the treated water is sent suddenly in the pipes of the spreading system. Therefore, this water arrives in force in these pipes and is distributed much better over the entire spreading system and no longer only the first few meters of this system. In addition, such a positive device does not require electrical energy or over-depth for its installation.

Other objects, advantages and characteristics of the present invention will emerge from the description which follows, by way of example, with reference to the accompanying drawings in which

 According to the embodiment shown in Figures 1 and 2, the flushing device and liquid distribution 10 according to the invention consists of a bucket II of triangular section, a pivoting support 12, a siphon 13a, two support elements 14 and 15 and a ballasting device 16.

 The bucket 11 has two longitudinal walls 17 and 18 and two transverse walls 19 and 2020. (Figure 3).

The apex A of the triangle formed by the bucket rests in a recess 21 formed in the support. pivot 12. The walls 17 and 18 are deliberately asymmetrical with respect to the vertex A
As shown in Figure 1, that is to say when the bucket is in the rest or filling position, the longitudinal wall 17 rests on the support element 15. The center of gravity of the device is then located on the left of it.

 The siphon 13a has an inlet pipe 22 and a drain pipe 23.

 The ballasting device 16 is adjustable and can be moved along the longitudinal wall 18.

 The longitudinal wall 18 has a.

abrupt enlargement 24 in the vicinity of its upper part.

 The operation of such a device is described below.

 Water is introduced into the bucket it in the direction of arrow F, the bucket being initially in the position shown in Figure 1, called the rest or filling position.

 The siphon 13a is defused and the water level inside the bucket rises. When the water level reaches the sudden widening 24, a slight variation in the water level causes a very rapid displacement of the center of gravity of the system to the right in FIG. 1.

 Therefore, the bucket 11 pivots abruptly on its apex A and the longitudinal wall 18 of the bucket comes to bear on the support element. 14. As a result, water suddenly enters the interior of the inlet pipe 22 of the siphon and initiates it. The priming of the siphon causes the bucket 11 to be emptied by the evacuation pipe 23 of the siphon.

 When the bucket is partially. emptied, its center of gravity quickly switches back to the left (Figures 1 and 2) and the longitudinal wall 17 comes to bear on the support element 15. The siphon thus defuses at the end of the emptying period, and l 'auget fills up again.

 Thanks to the rapid tilting of the bucket II, an abrupt and high-capacity emptying of the quantity of water contained inside the bucket. This water is therefore evacuated by sudden jerks and in a large volume.

 A fast and efficient flush is thus carried out.

 It can be seen that by displacement along the longitudinal wall 18, of the ballasting device 16 and of the siphon, it is possible to adjust the volume of water poured with each flush. Indeed the position of the ballasting device 16 on the longitudinal wall 18 allows. to determine the degree of filling of the bucket 11 at the time of its tilting.

 It should however be noted that this ballasting device can be omitted and advantageously. replaced by a modification of the shape of the bucket thus making it possible to shift the position of the center of gravity of the bucket.

 As shown in FIG. 3, as a variant, the device according to the invention can be provided with several siphons 13a, 13b, 13c.

 Therefore the flow of the flush is significantly increased or biased and the distribution of the discharged liquid is improved.

 As shown in Figure 4 it is possible to provide the device according to the invention with one or more partitions. In the embodiment shown, the device is provided with a single partition 25 of any shape, dividing the bucket 11 into two basins 26 and 27.

 A first siphon 13a is. placed along the longitudinal wall 18 and a second siphon 13d is placed along the longitudinal wall 17.

 The water arrives in the two basins according to arrow F. The operation of such a device is essentially analogous to that described above. However, such a device has a siphon associated with each of its longitudinal walls and therefore, whatever the wall. longitudinal bearing on the support elements 14 or 15 (not shown), one of the two siphons is always primed and allows the emptying of the corresponding basin. Such a device therefore allows continuous operation of the flush and this at a high flow rate.

 The positioning of the partition 25 defines the volume of each of the basins 26 and 27. If one is looking for an asymmetry of these two basins, that is to say a different volume of evacuated water according to each siphon, it suffices to move the partition in the bucket 11. As a variant (not shown), the position of the partition inside the bucket It is adjustable.

 Of course, the two variants shown in Figures 3 and 4 can be combined.

 A device as shown in Figures 1 to 4 is associated with a septic tank called "all water" (Figure 5).

 The device according to the invention is placed in a flushing compartment 28, so that the device according to the invention collects the treated water coming from the septic tank. The hunting device according to the invention allows. thus to send by sudden jerks a determined volume of water, according to a defined flow rate, in the conduits of a spreading system 40 associated with the septic tank.

 It should be noted that thanks to the device according to the invention, the treated water is sent suddenly. in the spreading system pipes and therefore the treated water is better distributed along these pipes before infiltrating into the ground. In addition, such a device directly integrated into a septic tank does not require that said tank to be buried more deeply.

 As shown in the embodiment shown in FIGS. 6a and 6b, it is possible to have a larger liquid flush volume than the volume of liquid contained in the bucket 11.

 Elements similar to those previously described have the same reference numerals.

 The bucket II according to this embodiment is identical to those already described.

 Here, the new element is the inlet pipe 30 for the treated water.

 This pipe has a bend 31 turned towards the upper part of the bucket. The mouth 33 of the elbow 31 is located at a markedly higher level than the opening of the inlet pipe 22 of the siphon 13e.

 The device according to this embodiment is.

associated with a tank 32 in which the pipe 30 originates.

 The operation of such a device is. described below.

 When the bucket is being filled (FIG. 6a) the treated water coming from the tank 32 penetrates through the curved pipe 30 into the bucket 11.

The siphon is defused.

 After tilting. abrupt of the bucket in its emptying position (Figure 6b) the siphon 13 starts, Therefore the water contained in the bucket 11 is sucked by the siphon and discharged. However being. given that the water level in the tank 32 is higher than the mouth 33 of the bent pipe 30, due to the principle known as "communicating vessels", the tank 32 continues to pour into the bucket 11 until that the level of the liquid contained in the tank is identical to that of the mouth 33. As a result, the flushing carried out not only made it possible to evacuate the water which was contained in the bucket, but also made it possible to evacuate part of the water contained in the tank 32 (see the hatched part in FIG. 6a) .We use this arrangement to produce a device for distributing liquid constituted by a small trough, while having a large hunting volume.

 The fact that the bucket can be small implies that it can tip quickly and easily which is an important factor in system reliability.

 The tank 32 can be a septic tank.

It should be noted that thanks to the use of such a liquid distribution device, the spreading system associated with the septic tank is much better used. On the other hand, such a device does not require implantation at a greater depth of the septic tank with which it is associated.

 it should be noted that the liquid distribution device according to the invention allows the sudden sending of a certain amount of liquid, whatever this liquid.

Thus, such a device can be used to add to a given quantity of liquid a certain quantity of another liquid.

 For example, a device according to the invention can be used to add chlorine to water.

 To improve the operation of the device according to the invention, namely, to accelerate the movement of the center of gravity and to facilitate priming of the siphon, it is possible to place a constriction on the outlet pipe of the siphon. A second constriction can also be placed at the entrance to the spreading system. It has been noted that such an arrangement clearly improves the operation of the device according to the invention.

 it should be noted that the device according to the invention can be associated with filters, that it can allow the management of liquids, and / or hydraulic regulation and / or metering. Likewise it can be used in any treatment. water (used, industrial, potable).

 As a variant, not shown, the device according to the invention comprises a plurality of buckets of identical or different shape and size. Each of these buckets is provided with one or more siphons arranged on the same longitudinal wall or on each wall.

 It should be noted that the device according to the invention may comprise a plurality of fixed buckets associated with tipping siphons or a plurality of tipping buckets associated with fixed siphons with respect to the troughs with which they are associated.

 Likewise, the device according to the invention may comprise at least one tilting bucket associated with at least one tilting siphon (not shown).

 Of course the present invention is not limited to the embodiments described above, but encompasses any variant within the reach of ordinary skill in the art. To this end, the device according to the invention can be provided with a tilting siphon whose sudden movement can be triggered by a displacement of the center of gravity, a float or an associated drainable tank and no longer of a tilting bucket. Similarly, the tilting bucket can be of any suitable shape and size.
