Abstract
A device for separating solid matter conveyed by waste and/or rain water effluent comprising an upstream zone in which the effluent to be treated emerges, and which is discharged by overflow, by means of a spillway 1, to a downstream zone 3. The device includes at least one removable basket 4 provided with s sieve 6 positioned in at least one frame (10 in Fig. 3a) disposed on the spillway 1 between the upstream zone and the downstream zone, the solid matter being collected in the basket 4.
Description
2365799 DEVICE FOR SEPARATING SOLID MATTER IN AN EFFLUENT The present
invention relates to a device for separating solid 5 matter conveyed by a waste or rain water effluent in drainage installations collecting this water with a view to taking it to purification plants.
In general terms, waste water and rain water is discharged to 10 treatment plants by simple pipes, so that, in the event of heavy rain and storms, the flow of water contained in these pipes becomes much greater than in dry weather, and cannot be treated in the purification plants.
15 To resolve this problem, overflow or spillway devices are known which prevent any hydraulic overload of these purification svstems under such conditions. These spillways are generally disposed at strategic points on the water collection system and thus protect the plants by discharging the overflow to close-by 20 watercourses or rivers.
These devices are in the majority of cases simple structures which allow the solid matter conveyed by the waste and/or rain water to leave the system with the overflow. Thus they 25 frequently discharge sewer waste and other household waste into the watercourses. These pollutants are unfortunately harmful to the surrounding flora and fauna and affect the appearance of the watercourses and rivers, often causing complaints from the public.
To overcome this problem, there exist spillways which include plates forming a barrage so as to prevent the solid matter from being discharge to the watercourses. However, these systems are not designed to comply with current standards.
Different types of grilles and filter bags are also known, 5 produced for this purpose and disposed at the spillway in order to collect and contain the solid matter and prevent it being driven into the drainage systems. Unfortunately these devices have many drawbacks: for example, such bags have a tendency to break, to slow down the overflow when they are full, their 10 service life is often short and their weight, when full, is generally too great to enable them to be handled by only one person. With regard to the grilles, these pose hydraulic problems, also presenting problems of maintenance when disposed in confined spaces, and are often expensive to produce.
The present invention aims therefore to mitigate these drawbacks by proposing a spillway device for minimising pollution of watercourses without affecting the hydraulic performance of the drainage installation, the maintenance of 20 this device being able to be carried out by only one person.
According to the present invention, there is provided a device for separating solid matter conveyed by waste and/or rain water effluent comprising an upstream zone in which the said effluent 25 to be treated emerges, and which is discharged by overflow, by means of a spillway, to a downstream zone, wherein at least one removable basket provided with a sieve is positioned in at least one frame disposed on said spillway between said upstream zone and said downstream zone, said solid matter 30 being collected in said basket.
For a better understanding of the invention and to show how the same may be carried into effect, reference will.now be made, by way of example, to the accompanying drawings, in which:- Figure 1 is a partial view in perspective of a device for separating solid matter in an effluent mounted on a spillway of a drainage installation; 5 Figure 2 is a perspective view of a removable basket of the device; and Figures 3a to 3c are perspective views of three variants of a frame of the device.
Referring to Figure 1, which partially depicts a drainage installation, it can be seen that a waste and/or rain water effluent coming from an upstream zone arrives at a spillway 1, flowing through a pipe 2 in the direction of the arrow F. This 15 pipe 2 is generally in the form of a semi-cylinder, one of the rims of the latter fulfilling the role of a spillway 1. Thus, in the event of heavy precipitation, the excess waste and/or rain water flow passes over the spillway 1 and overflows, downstream of the latter, into a discharge pipe 3 (or 20 downstream zone), itself opening out for example into a closeby watercourse or river.
In addition, between the spillway 1 and the said pipe for discharging excess effluent, there is disposed at least one 25 device (in Figure 1, three in number) for separating solid matter conveyed by the effluent when the latter passes over the spillway.
Naturally, this device, which is in the form of modules 30 disposed alongside each other, can be adapted to any type of spillway by varying the number of modules, notably according to the width of the spillway.
Referring now to Figures 2 and 3a to 3c, it can be seen that this devLce is basically composed of a removable basket 4 (Figure 2) and a frame 5 supporting the latter (Figures 3a to 3c), the basket making it possible to connect the solid matter 5 which might pollute the watercourse or river into which the discharge pipe 3 emerges. To do this, the removable basket has a sieve 6 which retains the solid matter and allows the overflow water to pass.
10 According to one advantageous characteristic (cf Figure 2), the sieve 6 of the removable basket has a rounded base 7 and a rim 8 to which two side handles 9 are fixed so as to facilitate the removal and cleaning of the basket.
15 According to another advantageous characteristic, the rounded base of the sieve 6 has a U shape so as to facilitate the emptying of the basket. This is because the absence of corners at -the base 7 of the sieve 6 prevents solid matter from remaining blocked at the bottom of it when a person comes to 20 empty the basket.
In addition, the frame 5 on which the removable basket 4 is positioned is designed so as to be able to support the weight of a man, and the basket is sized so as to be able to be 25 removed, even when it is full, by only one person. This is because the dimensions of each module must be in conformity with current regulations (removal of the removable basket by only one person).
30 According to yet another advantageous characteristic, the frame 5 has a mount 10 for supporting the basket 4 and at least one projecting lug 11 for fixing the frame to the spillway 1.
Preferably (cf Figures 3a to 3c), the frame has four lugs thus ensuring good fixing to the spillway.
The frame also has at least one deflector plate 12 for 5 directing the effluent coming from the upstream zone in the direction of the removable basket. This plate, which forms a right or obtuse angle with the direction F of flow of the effluent (in the clockwise direction), has the advantage of diverting the overflow and thus concentrating the solid matter towards the basket.
The frame comprises at least one parapet plate 13 for preventing overflow of the effluent outside the basket.
15 This last advantageous characteristic shown in Figures 3b and 3c is basically intended to equip the modules disposed at each end of the spillway 1, notably when the length thereof does not make it possible to receive a whole number of modules.
20 The present device as described offers many advantages:
notably, it proposes a device for separating solid matter which is economical, adaptab'Le to any size of spillway without affecting the hydraulic performance of the drainage installation, and which can be emptied and cleaned by only one 25 person.
