    [0001] DEVICE FOR PREPARING AEROSOL CONTAINERS FOR THEIR ELEVIATION OR RECYCLING AND INSTALLATION COMPRISING SUCH A DEVICE. OBJECT OF THE INVENTION [0001] The present invention relates to a device for preparing aerosol containers for their elimination or recycling and an installation comprising such a device. State of the art [0002] Waste, particularly household waste, comprises a multitude of objects, residues or substances, resulting from the activity or the human diet. Some are inert and not very dangerous, while others are more dangerous to treat or recycle. Household waste generally includes a multitude of substances of very different nature, some mixed waste is non-recyclable, such as some plastic packaging, while others are recyclable as newspapers magazines, cardboard packaging, plastic bottles, food blocks, boxes and aerosols in steel or aluminum. The collection of waste is usually done through traditional household garbage collection, selective collections, collections of bulky items and those brought in waste disposal. Generally, all the previously sorted waste, whatever their mode of collection, arrive in sorting centers in which they are prepared for recycling or disposal. They are eventually sorted again, before being packaged and sent to recovery centers for processing into new raw materials. With regard to the preparation of the recycling of objects or metal residues, it generally performs a first separation of these objects from the remains of the waste by a magnetic separation to recover first the ferrous objects, then a separation, for example by eddy current, to sort the non-ferrous objects of metal objects. The waste thus sorted is then packaged generally in the form of bales using presses, a packaging which proves to be the easiest at this stage of recycling. Indeed, in the sorting centers, the use of grinders that reduce powdered metal containers, or at least small particles, is not feasible because small particles, especially powders, are difficult to condition for transport and subsequent treatment and requires a lot of protective equipment to avoid particulate contamination of industrial facilities, the environment and people who are led to handle them. As regards aerosols, pressurized containers made of aluminum or steel, grinding is also not possible because of the high risk of explosions that would damage the grinding equipment. Similarly, packaging directly in the form of bales also has the disadvantage of inducing explosions or fires due to crushing and / or indirect piercing of containers, releasing residual contents still present (such as gas or mixture of propellants, the active product (s) and possibly solvents), which are generally highly flammable. In addition, it is generally not recommended to isolate aerosols from the sorted aluminum stream so as not to concentrate them at a point in the sorting center as this increases the risk of exposure. For packaging directly in bales, it has been proposed to equip the packaging devices, for example balers, explosive atmosphere detectors and associated ventilation, to automatically stop the device. conditioning and to trigger ventilation as soon as flammable or explosive vapors are detected. It has also been proposed solutions for drilling aerosols before their packaging in the form of bales, solutions that also recover the residual gas before it escapes into the environment. The document FR 2 664 834 describes a device comprising two plates, one fixed the other mobile, allowing the flattening and piercing of aerosols. This device has the disadvantage of operating batch, so discontinuous and, due to significant mechanical stresses, to present a rapid wear of the various elements of the device [0011] Continuous treatment devices are also known. The document FR 2 643 837 describes the piercing of aerosols, arranged on a rotating barrel, by means of a hollow needle for transferring the contents into a low-pressure separation tank, placing in communication the two aerosol enclosures -cuvette allowing a separation of gases from liquids, the gases being compressed to be transferred to storage tanks. The document WO2009156757 describes an aerosol treatment device comprising a perforation element for piercing in a first sealing element of the aerosol and a second perforating element for piercing in a second sealing element. aerosol. The document WO9207763 describes the destruction of aerosols using a cutting device passing through a slot in an aerosol feed tube for piercing aerosols, their contents being collected in a collecting tank. However, these solutions have the disadvantage of treating an aerosol at a time and are therefore not suitable for treating large volumes of aerosols. It has also been proposed, as described in document WO9009248, an aerosol treatment process in which the waste is compressed in a screw press disposed in a gas-tight enclosure and the gases escaping from the aerosols being collected on the walls of the enclosure. Similarly, the document EP 0 456 115 describes a device under nitrogen pressure in which the aerosol is frozen in a cooling bath before being cut. The document WO2010125393 describes an aerosol treatment device comprising a compacting device, a device for collecting released gases and a fire extinguisher in a negative pressure chamber. Because of their confinement in gas-tight enclosures, the solutions described above are not an implementation and easy maintenance. Furthermore, none of the solutions of the state of the art offers a solution for managing the so-called "undesirable" objects, namely metal objects, in particular aluminum or steel, present in the stream from a waste sorting line, which are not aerosols, such as for example beverage cans, cans, cans of beer, engine parts or pressure cookers. In addition, none of the solutions of the state of the art offers a solution to handle large objects to be recycled, such as cartons, rigid or flexible plastics, or to avoid a jam in case of introduction of a large volume of aerosols. OBJECTS OF THE INVENTION The present invention aims to provide a device for preparing aerosol containers for their elimination or recycling and an installation comprising such a device, which do not have the drawbacks of the state of the art. . The present invention aims to provide a solution that is an alternative to existing solutions already. The present invention aims in particular to provide a treatment solution, batch and continuous, a multitude of aerosols to remove residual gases and liquids that may be there, before packaging by compaction. The present invention also aims to provide a solution for packaging by compaction in balers or packets.
