Definitions

• the present invention relates to an installation for breeding animals.
• the animal husbandry of animals, especially pigs, requires specific facilities: it is necessary to regularly wash the droppings produced by these animals to allow their growth under proper sanitary conditions.
• Document FR 2,650,152 discloses an installation for rearing animals, comprising an animal station area, means for brutally expelling a cleaning fluid in said zone in order to wash this zone and, situated opposite said flushing means with respect to said zone, a recovery channel of the mixture formed by said cleaning fluid and the droppings expelled by this fluid.
• the cleaning fluid can be of various types: it can be water, or excreted waste (biological and / or chemical and / or physical), or even a mixture of these two fluids .
• the manure expelled from the station area can be recovered in settling basins, and it is then the liquid fraction of the decanted manure that can be used to clean the station.
• the present invention has the following aims in particular:
• the bucket tilts under the sole effect of the displacement of its center of gravity during its filling, this tipping having the effect of sending a flow of cleaning fluid at a time very high and very brutal in the station area of the animals, which allows to hunt a good part of the animal dung fell in this area.
• a low fluid flow rate is sufficient to ensure the filling of the bucket, so that it is not necessary to use expensive pumping means.
• the tilting of the bucket also requires no particular mechanism, so that the installation according to the invention is very simple and inexpensive in initial investment, maintenance and power consumption.
• said bucket comprises a trough arranged so that when its filling level by said cleaning fluid has reached a predetermined threshold, the center of gravity of the assembly formed by said substantially empty bucket and said chute thus filled has moved to a point such that said bucket switches from said flushing position to said filling position, so as to refill said cleaning fluid.
• said bucket has a substantially asymmetrical trapezoidal profile.
• This trapezoidal shape is very simple to manufacture, and makes it easy to obtain the above-mentioned function of displacement of the center of gravity as and when the bucket is filled.
• said trough has a substantially horizontal bottom when said trough is in the filling position, said trough comprises a bottom which is inclined with respect to the horizontal when said trough is in the filling position, this bottom comprising a drain orifice allowing a leakage flow rate much lower than the filling rate of said cleaning fluid; said installation comprises siphon means interposed between said pit and said channel,
• said cleaning fluid originates at least in part from the recycling of the excreted waste from said station area.
• FIG. 1 shows a schematic top view of a livestock building equipped with an installation according to the invention
• FIG. 2 shows a perspective view of a bucket forming part of the installation according to the invention
• FIGS. 3 and 4 are side views of two variants of the bucket of Figure 2;
• FIG. 5 is a sectional view along the line V-V of the building shown in Figure 1;
• FIG. 6 schematically represents the fluid circuit of the installation according to the invention;
• FIG. 7 is a sectional view along the line VII-VII of the building shown in Figure 1, which shows a bucket of the installation according to the invention which begins to fill with a cleaning fluid;
• FIGS. 8 to 11 are similar to FIG. 7, the cup being respectively in the following situations: end of filling with the cleaning fluid, tilting and flushing of the cleaning liquid, filling of the chute of the bucket, return of the bucket at the initial position.
• FIG. 1 shows that the breeding building comprises a plurality of parts 1a to 1f separated from each other by partitions 3a to 3d.
• a central corridor 5 passes in the middle of the building, thus serving on the one hand the parts 1a, 1c, 1e, and on the other hand the parts 1b, 1d, 1f, thanks to doors 7a, 7b placed appropriately.
• buckets 11a to 11f of elongated form in which open conduits 13a, 13d, provided at their ends with valves 15a to 15d.
• each bucket 11 can optionally be subdivided into subsections.
• Figures 2 to 4 which shows that each bucket preferably has a profile, that is to say a cross section at its greatest length, having substantially the shape of an asymmetrical trapezoid.
• the mouth 17 and the bottom 19 of the bucket are parallel to each other, the surface of the mouth 17 being significantly greater than that of the bottom 19, and one 21 of the two inclined walls of the bucket has an area greater than other 22.
• the bucket 11 is pivotally mounted about an axis A situated in the vicinity of the edge located between the bottom 19 and the inclined wall 21.
• the bucket 11 comprises, fixed to the outside and in the upper part of the inclined wall of smaller area 22, a chute 23 defined by a bottom 25 and two end panels 27a, 27b, this chute extending preferably over substantially the entire length of the bucket 11.
• the bottom 25 of the chute 23 is substantially parallel to the bottom 19 of the bucket 11, so that the bottom 25 of the chute is in substantially horizontal position when the bucket 11 is in the position shown in Figure 3.
• the bottom 25 of the chute 23 is inclined relative to the bottom 19 of the bucket 11, so that the bottom 25 of the chute 23 is inclined relative to the horizontal when the bucket 11 is in the position shown in Figure 4.
• the bottom 25 of the chute 23 is provided with an orifice 29 located in the vicinity of the wall 22 of the bucket 11.
• the floor of the breeding building comprises gratings 31a, 31b, 33 arranged both in the pieces 1a, 1b and in the passageway 5.
• gratings 31a, 31b Under the gratings 31a, 31b are pits 35a, 35b whose bottom 36a, 36b, preferably concrete, has a slight slope (for example 1 cm per 1 meter) in the direction of the corridor 5.
• a channel 37 Under the grating 33 of the corridor 5 is a channel 37 extending along the entire length of the corridor 5, and whose bottom is also preferably made of concrete.
• siphon devices 39a, 39b are arranged in the areas where the pits 35a, 35b open into the channel 37, so as to prevent gas exchange between the corridor 5 and these pits.
• the siphon devices 39a, 39b are formed by channels integral with the upper edges of the channel 37, in which are partially immersed the lower ends of the partitions 41a, 41b separating the corridor 5 from pieces 1a, 1b.
• FIG. 6 shows a possible embodiment of the fluid circuit involved in the installation according to the invention.
• each bucket 11 can be brought into fluid communication with the channel 37 via the associated pit 35.
• Suitable conduits 43 connect the outlet of the channel 37 to a recycling facility 45.
• the term "recycling" is a generic term that covers any mode of treatment of the effluents recovered at the outlet of the channel 37.
• These modes of treatment can be of biological type (bacteriological reactor by example) of chemical type, or even of physical type.
• the recycling means 45 are of physical type, and consist in fact of a simple settling tank in which the effluents separate into two fractions: a liquid upper fraction 47 (consisting essentially of urine) and a solid lower fraction 49 (consisting essentially of fecal matter).
• This room is preferably closed in its upper part by a removable cover 55, and the bottom 57 of this room is located in the extension of the bottom 36 of the pit 35, and has a slope at least equal to that of the latter.
• the largest inclined wall 21 of the bucket 11 is preferably located opposite the pit 35.
• Pump 51 is operated and valve 15 is opened (see FIG. 6) so that fluid from recycle device 45 flows from line 13 into cup 11 at a substantially constant rate.
• the cup 11 fills with fluid, which, given the asymmetry of this cup, tends to shift the center of gravity of the assembly formed by the cup and the fluid towards the largest wall inclined 21, as this is symbolized by the arrow F shown in Figure 8.
• the flow of the fluid thus removed is very important, typically of the order of 35,000 m 3 per hour for a bucket having a volume of the order of 9 m 3 , adapted to a room 1 of a length (between the wall 9 and channel 37) of about 20 m.
• the flush of fluid symbolized by the arrows C of Figure 9, has the effect of removing a large part of the droppings located in the bottom 36 of the pit 35, and from animals stationing on the grating 31. These droppings are thus fed into the channel 37, then to the recycling device 45.
• the chute 23 is at the right of the pipe 13.
• the orifice 29 provided in the bottom 25 of the trough 23 allows, in this variant, to ensure that the chute ends by emptying completely while the bucket 11 fills.
• the installation according to the invention makes it possible to generate, at regular time intervals, a very high flow of pit cleaning fluid from a livestock building.
• siphon means 39a, 39b shown in FIG. 5 make it possible to prevent the fresh air situated in the corridor 5 from reaching the parts 1, thus making it possible to maintain the latter at a temperature sufficiently high for the beasts.
• the installation according to the present invention does not require any heavy pumping means or any particular actuating mechanism.
• This installation very simple and reliable design, is inexpensive to install and maintain, and consumes relatively little power.
