Description

TECHNICAL FIELD The present invention relates to a plant for grinding and recycling of organic waste intended in particular to be partly mounted below the bottom of a collecting vessel such as a sink or the like, and to reduce and especially to recycle ecologically the volume of said organic waste.

PRIOR ART It is widely used to use grinding plants for crushing organic waste in order to reduce its volume thus limiting the hygiene problems due to the decomposition of said waste and those related to its storage and disposal. Said grinding plants generally comprise a grinder mounted below the bottom of a collecting container such as a kitchen sink, for example. Most of these known mills have two distinct elements: the engine and the grinding chamber. Thus, when cold water is poured into the sink to drive the organic waste to the drain of said sink, said waste enters the grinding chamber comprising a disk equipped with metal hammers and a spray ring which is in general rule formed by the toothed wall of said grinding chamber. The motor then actuates the disc which, by turning, pushes the waste towards said spray ring. In a few seconds, the organic waste is reduced into small particles which are then evacuated through holes on the ring to an evacuation pipe, then to a septic tank or a treatment plant. The main disadvantage of this type of device is that it does not propose to recycle the particles of organic waste thus obtained for an energy use for example.

DISCLOSURE OF THE INVENTION The present invention aims to remedy this drawback by proposing a plant for grinding and recycling organic waste making it possible to reduce the volume of said organic waste by grinding it but also to recycle the particles of organic waste resulting from grinding to for example, energy and ecological applications. In addition, the plant for grinding and recycling of organic waste according to the invention is economical, easy to implement and has a small footprint because it is partly disposed under a sink. In this regard, the invention relates to a plant for grinding and recycling organic waste comprising at least one grinder intended in particular to be mounted below the bottom of a collection container such as a sink or the like and suitable for crushing waste organic entrained by rinsing water to the drain of said sink, characterized in that it comprises at least one dipping tank containing said mill and adapted to receive a mixture (rinsing water-particles of organic waste) from grinding by said mill, a first valve for supplying water to said mill, a first pump contained in said dip tank coupled to an outlet for discharging said mixture (rinsing water-particles of organic waste) to the outside of said dip tank. Advantageously, the grinding and recycling plant comprises at least one composter coupled to said evacuation of the quench tank and comprising at least one storage tank adapted to receive said mixture (water

ZYTACI-EN-1_TEXTE REMOVAL_RG / CD - 3 - rinsing-particles of organic waste). Said storage tank comprises at least one discharge orifice located substantially in the middle of said storage tank and a filter mass intended to be completely covered by said mixture (rinsing water-particles of organic waste) stored in said storage tank under the discharge port, said storage tank being covered respectively by a box. Preferably, the composter comprises a 10 drains network located under the storage tank and arranged to recover the excess water filtered by the filter mass. Preferably, the first pump is connected to the composter by means of at least one discharge pipe connected to the first pump, to a second valve and to a pipe network whose free end of one of its pipes is connected to the discharge port of the storage tank. Advantageously, the first valve is a solenoid valve controlled by a computer capable of determining the optimum water concentration of said mixture (rinsing water-organic waste particles). According to an alternative embodiment, the composter comprises a first, a second and a third storage tank and the pipe network comprises at least 25 first, second and third pipes respectively connecting the second valve and the first, second and third storage bins. Finally, according to this same variant embodiment, the second valve is a four-way solenoid valve controlled by a time stamp.

Brief Description of the Figures Other advantages and features will become more apparent from the following description of the invention.

ZYTACI-FR-1_TEXTE DEPOSE_RG / CD refers to the attached single figure which is a diagram of the preferred embodiment of the grinding and recycling plant according to the invention.

BEST WAY OF CARRYING OUT THE TECHNICAL INVENTION The following will be described, with reference to this preferred non-limiting embodiment, a grinding and recycling plant intended in particular to be partly mounted below the bottom of a collecting vessel such as a sink of a kitchen of a single house; however, the crushing and recycling facility can obviously be used for other types of collecting vessels and in other types of habitats such as, for example, multi-dwelling buildings.

Referring to the single figure, the grinding and recycling plant 1 according to the invention comprises a grinder 2 arranged to be mounted below the bottom of a sink 3 in a substantially sealed manner, a dip tank 4 containing said grinder 2 and adapted to contain the mixture (rinsing water-particles of organic waste) from grinding, a first valve 5 for supplying water if necessary said mill 2, a first pump 6 also contained in said dip tank 4 in below said mill 2 for discharging said mixture (rinsing water-particles of organic waste) to a composter 10 through a discharge pipe 7, a second valve 8 carried by said discharge pipe 7 and a pipe network 9 connected at said second valve 8.

The mill 2 and the first pump 6 are preferably coupled so that one can not work without the other. The mill 2 is a grinder of the type known from the prior art and comprises two distinct elements: the

ZYTACI-EN-1_TEXTE DEPOSE_RG / CD 2965737 - 5 - motor 21 and the grinding chamber 22. Thus, when cold rinse water is poured into the sink 3 to drive the organic waste to the drain 31 said sink 3, said organic waste enters the grinding chamber 22 containing a disc (not shown) and a spray ring (not shown). The motor 21, which is preferably a smaller permanent magnet electric motor, lighter and more efficient than an induction motor, then drives the disc which, by turning, pushes said organic waste towards said spray ring. The organic waste is then reduced to small particles and the mixture (rinsing water-organic waste particles) is subsequently discharged into the quenching tank 4 via an evacuation pipe 23. The crusher 2 is preferably connected to the mains water network through the first valve 5 and a supply line 51 connecting said mill 2 to said valve 5. Said mill 2 can also be connected to a water reserve. The first valve 5 is advantageously a solenoid valve controlled by a computer (not shown) able to determine the optimum water concentration in said mixture (rinsing water-organic waste particles) to obtain an ideal compost 25 promoting decomposition and fermentation said organic waste. Said computer is connected in particular by a cable 18 to at least one probe 19, preferably electronic, placed in the composter 10 and measuring the humidity level in the latter. In another embodiment not shown, the first valve 5 may be manual and coupled to a non-electronic visual probe disposed in the composter 10. In this embodiment, the first valve 5 will be opened or closed by a person for adjust the

ZYTACI-FR-1_TEXTE DEPOSE_RG / CD 2965737 - 6 - concentration of water in said mixture (rinsing water-particles of organic waste) as a function of the indications observed on said visual probe. Said dip tank 4 is mounted substantially tightly around the mill 2 and is arranged to contain the mixture (rinsing water-particles of organic waste) discharged through the discharge pipe 23 of said mill 2. The dip tank 4 further contains said first pump 6 for discharging said mixture (rinsing water-organic waste particles) from said dip tank 4 to a composter 10. Said first pump 6 is preferably of the electric lift pump type and is placed at the bottom of said dip tank 4 immersed in said mixture (rinsing water-particles of organic waste) and connected to the discharge pipe 7. To overcome a possible power failure or damage to the first 6, the soaking tank 4 further comprises an overflow 41 connected to the drain pipe of the sink 3 by a pipe (not shown e) and for discharging the contents of the dip tank 4 to the city network of wastewater treatment. Similarly, it is well understood that the quenching tank 4 has orifices arranged to allow the passage substantially sealingly of the discharge pipe 7, the supply pipe 51, the electric cables 24, 61 connecting the 30 respectively. motor 21 of the mill 2 and the first pump 6 to a power supply 17. The composter 10, which receives said mixture (rinsing water-particles of organic waste), preferably comprises a first, a second and a third tank of

ZYTACI-FR-1 TEXTE DEPOSE_RG / CD - 7 - storage 11, 12, 13 of said mixture each respectively connected to a first, a second and a third pipe 91, 92, 93 of the pipe network 9. It goes without saying that the Composter 10 may comprise only one storage bin, however this configuration with three storage bins 11, 12, 13 makes it possible to maintain a time interval of at least one week between each filling of one of the three storage bins. 11, 12, 13 thus promoting the fermentation of said mixture (rinsing water-particles of organic waste) recently deposited in each of said three storage tanks 11, 12, 13. To do this, the network of pipes 9 is connected to the pipe discharge 7 connected to the first pump 6 through the second valve 8. The latter is advantageously a four-way solenoid valve controlled by a time stamp (not shown) to change, each week, the connection between the said pipe network 9 and said discharge pipe 7. Thus, the first week for example, the second valve 8 allows only the passage of the mixture (rinsing water-organic waste particles) of said discharge pipe 7 to the first pipe 91 of the pipe network 9 only allowing the filling of the first storage tank 11. Then, the second week for example, the second valve 8 only allows the passage of the mixture (rinsing water-particles of organic waste) from said discharge pipe 7 to the second pipe 92 of the pipe network 9 only allowing the filling of the second storage tank 12. Finally, the third week for example, the second valve 8 only allows the passage of the mixture (water rinsing-particles of organic waste) of said delivery pipe 7 to the third pipe 93 of the pipe network 9 allowing only the filling of

ZYTACI-EN-1_TEXT REMOVE_RG / CD third storage bin 13. The previously described cycle is then repeated every 3 weeks. Each first, second and third storage tank 11, 12, 13 comprises a discharge orifice 11a, 12a, 13a, of vertical axis, situated as high as possible and laterally substantially in the middle respectively of each of the first, second and third bins. storage 11, 12, 13 in order to always be above the level of the mixture (rinsing water-particles of organic waste) already stored. Said delivery port 11a, 12a, 13a is further connected respectively to the free end of the first, second and third pipes 91, 92, 93 of the pipe network 9. This configuration allows, on the one hand, the mixture (water rinsing-particles of organic waste) from each discharge port 11a, 12a, 13a to spread well over the entire surface of said first, second and third storage tank 11, 12, 13 associated and other on the other hand, a good oxygenation of said mixture (rinsing water-particles of organic waste) favoring the decomposition and the fermentation of said organic waste. In addition, each first, second and third storage tank 11, 12, 13 comprises a filter mass 11b, 12b, 13b completely covered by the mixture (rinsing water-organic waste particles) stored in each of said first, second and third storage tanks 11, 12, 13. Said filtering mass 11b, 12b, 13b allows to pass the excess water contained in said mixture (rinsing water-organic waste particles) while retaining the flow of suspended solids and preferably consists of a geotextile envelope filled with pozzolan. It goes without saying that we will be able to use an entirely different

ZYTACI-FR-1 TEXTE DEPOSE_RG / CD - 9 - filtering material such as synthetic foam without departing from the scope of the present invention. In addition, to recover the excess water filtered by each of the filter masses 11b, 12b, 13b, the bottom of each of the first, second and third storage tanks 11, 12, 13 has orifices (not shown) and the Composter 10 comprises a network of drains 14 located under all the orifices of the first, second and third storage tanks 11, 12, 13 and allowing the recovery of said excess water. Said network of drains 14 is advantageously connected by a recovery line 15 to a second pump 16 in order to use said excess water to water the garden, for example.

It is well known that, as for a growing medium, the aeration and the moisture of a compost are bound to obtain a decomposition and a fermentation of the organic waste: an excess of water decreases the quantity of air available in the volume of compost.

In addition, the heat released by the fermentation causes the evaporation of a large amount of water. The watering of said mixture (rinsing water-particles of organic waste) in fermentation allows, if necessary, to maintain a humidity level of 50 to 70%.

Composter 10, according to the invention, therefore comprises an aeration device (not shown) effective and adjustable. On the other hand, beating rains such as excessive evaporation by the sun can also slow down the process of fermentation of organic waste. Thus, each of the first, second and third storage tanks 11, 12, 13 is advantageously covered by respectively caissons 11c, 12c, 13c filled with

ZYTACI-FR-1_TEXTE DEPOSE_RG / CD 2965737 - 10 - soil and acting as gardens of aromatic or other plants, said gardens being advantageously watered by the excess water filtered by each of the filter media 11b, 12b, 13b from of the second pump 16. These gardens of aromatic plants allow, in addition to improving the aesthetics of said composter 10, to mask the odor generated by the decomposition and fermentation of said organic waste. In addition, each of the first, second and third storage tanks 11, 12, 13 advantageously comprises a probe 19 measuring the moisture content in each of said storage tanks 11, 12, 13 and being connected by at least one cable 18 a computer (not shown) able to drive the first valve 5 to obtain the optimum water concentration in said mixture (rinsing water-organic waste particles) to obtain an ideal compost promoting the decomposition and fermentation of said organic waste. Finally, it is well known that the decomposition of organic waste generates heat up to 80 to 90 ° C. It goes without saying that it is interesting to use this heat to achieve an additional heating of a house. Thus, each of the first, second and third storage bins 11, 12, 13 of the composter 10 may receive a heat sensor (not shown) of the coil type filled with a heat transfer fluid, preferably air or water. water, able to be heated by the heat generated the decomposition of organic waste. This heat sensor is preferably connected to the heating network of said individual house. The skilled person will have no difficulty in sizing the grinding and recycling plant 1 according to the invention, especially the first and second

ZYTACI-FR-1 TEXTE DEPOSE_RG / CD 2965737 - 11 - pumps 6, 16, the first and second valves 5, 8 and the composter 10, depending on the need and dimensions of the house receiving said grinding and recycling facility. With reference to the example described, the grinding and recycling plant 1 according to the invention comprises a composter 10 comprising a first, a second and a third storage tank 11, 12, 13. It can of course not include only one storage bin or even a greater number of storage bins.

Possibility of industrial application The grinding and recycling plant 1 according to the invention is intended to be used preferably in a single house; However, it goes without saying that this grinding and recycling plant 1 can also be installed in a collective housing building by equipping each of the sinks of the various apartments of said building with an assembly comprising a mill 2, a dip tank 4 , a first valve 5 and a first pump 6, and connecting said assemblies to a large composter 10 or a series of composters 10. Similarly, the grinding and recycling plant 1 can be implemented in buildings in collective use such as for example restaurants or school canteens. It is understood that the examples described are only particular illustrations and in no way limiting the fields of application of the invention.
