MÁQUINA RECICLADORA DE NEUMÁTICOS DESCRIPCIÓN OBJETO DE LA INVENCIÓN La presente memoria descriptiva se refiere a una solicitud de Patente de Invención, que según se expresa en el enunciado de esta memoria descriptiva, se refiere a una máquina recicladora de neumáticos, cuya finalidad estriba en permitir el reciclado de los neumáticos mediante la separación del caucho de los elementos metálicos, con la obtención de un granulado de material elástico de múltiples y diversas aplicaciones. TIRE RECYCLING MACHINE DESCRIPTION OBJECT OF THE INVENTION The present specification refers to an application for a Patent of Invention, which as expressed in the statement of this specification, refers to a tire recycling machine, the purpose of which is to allow the recycling of the tires by separating the rubber from the metallic elements, obtaining a granule of elastic material with multiple and diverse applications.
CAMPO DE LA INVENCIÓN Esta invención tiene su aplicación dentro de la industria dedicada a la fabricación de maquinaría para el reciclado de materiales, con independencia del campo de utilización.FIELD OF THE INVENTION This invention has its application within the industry dedicated to the manufacture of machinery for recycling materials, regardless of the field of use.
ANTECEDENTESDELAINVENCIÓN Como se sabe, desde hace años, el número de automóviles en circulación se encuentra en constante aumento, al haberse convertido el automóvil en un elemento imprescindible para el desarrollo de los pueblos. Los beneficios aportados por el automóvil a la sociedad quedan fuera de toda duda, sin embargo, no todo son ventajas. Los neumáticos que utiliza cada uno de los numerosos vehículos, sufren un lógico desgaste y, por tanto, deben sustituirse de forma periódica. Así, los neumáticos desgastados y sustituidos se convierten en un residuo no biodegradable que se acumula en los vertederos, y que hoy en día plantea uno de los mayores problemas de reciclado, puesto que el neumático está constituido fundamentalmente por acero y caucho, combinados en una compleja estructura que dificulta su separación y posterior reciclado. Teniendo en cuenta los inconvenientes anteriores, entre otros muchos, es por lo que ha sido ideada la invención que nos ocupa. En efecto, se trata de proveer de una máquina recicladora de neumáticos caracterizada porque 'separa los dos componentes básicos del neumático, el caucho y el acero, obteniendo un granulado de caucho que resulta reutilizable en numerosas aplicaciones como material elástico de relleno. Los restos metálicos pueden ser tratados de la forma habitual, resolviendo así por completo el problema del reciclado. Por parte del solicitante no se tiene conocimiento de la existencia en la actualidad de ninguna invención que presente las características que se señalan como idóneas.BACKGROUND OF THE INVENTION As it has been known, for years, the number of cars in circulation has been constantly increasing, as the car has become an essential element for the development of towns. The benefits provided by the automobile to society are beyond doubt, however, not all are advantages. The tires used by each of the numerous vehicles suffer logical wear and, therefore, must be replaced periodically. Thus, worn and replaced tires become non-biodegradable waste that accumulates in landfills, and which today poses one of the biggest recycling problems, since the tire is mainly made of steel and rubber, combined in a complex structure that makes it difficult to separate and later recycle. Taking into account the above drawbacks, among many others, is why the invention at hand has been devised. Indeed, it is about providing a tire recycling machine characterized in that it 'separates the two basic components of the tire, rubber and steel, obtaining a rubber granulate that is reusable in numerous applications as an elastic filler material. The metallic remains can be treated in the usual way, thus completely solving the recycling problem. On the part of the applicant, there is no knowledge of the current existence of any invention that has the characteristics indicated as suitable.
DESCRIPCIÓN DE LA INVENCIÓN La máquina recicladora de neumáticos que la invención propone, se configura en sí mismo como una evidente novedad dentro de sus múltiples campos de aplicación, llevando a cabo la separación del caucho y del acero que constituyen los neumáticos, permitiendo de este modo el reciclado de los mismos. De forma más concreta, la máquina recicladora de neumáticos objeto de la invención, está constituida por un rodillo que gira alta velocidad provisto de una serie de cuchillas que inciden repetidamente sobre el neumático, efectuando una acción de abrasión, impacto y desgarro, picándolo hasta dar lugar a su total desmenuzamiento.DESCRIPTION OF THE INVENTION The tire recycling machine that the invention proposes, is configured in itself as an evident novelty within its multiple fields of application, carrying out the separation of the rubber and steel that make up the tires, thus allowing recycling them. More specifically, the tire recycling machine object of the invention is made up of a high-speed rotating roller provided with a series of blades that repeatedly impinge on the tire, effecting abrasion, impact and tearing, chipping it until it gives place to its total crumbling.
Con objeto de que las cuchillas actúen de forma uniforme sobre toda la superficie del neumático, especialmente sobre la banda de rodadura, el neumático se afianza entre dos platos de apriete rotativos. La velocidad de rotación del neumático es considerablemente menor que la velocidad de giro del rodillo picador con objeto de favorecer -el picado uniforme y progresivo del neumático, siendo indiferente el sentido de giro de cada uno de ellos.In order for the blades to act uniformly on the entire surface of the tire, especially on the tread, the tire is clamped between two rotating clamping plates. The speed of rotation of the tire is considerably less than the speed of rotation of the chopper roller in order to favor -cut uniform and progressive tire, the direction of rotation of each of them being indifferent.
Para compensar el desgaste sufrido por el neumático y permitir el desmenuzado de neumáticos de diferentes diámetros, «1 rodillo picador también dispone de movimiento de traslación, lo cual permite el ajuste de su posición, garantizando la acción de las cuchillas sobre la superficie del neumático hasta el final del proceso de desmenuzado. La invención también contempla la posibilidad de que la fijación del neumático se realice mediante su inserción en un cilindro giratorio de diámetro adecuado, de modo que gire conjuntamente con el cilindro pero pueda desplazarse longitudinalmente por él, de forma que, disponiendo el eje del rodillo picador convergente con el del cilindro, el picado del neumático progresa según se desplaza por el cilindro, permitiendo de esta manera una alimentación continua del proceso de picado y desmenuzado del neumático, puesto que es suficiente con ir introduciendo los neumáticos por el extremo inicial del cilindro giratorio para que se empujen entre ellos hasta ser alcanzados por el rodillo picador.In order to compensate for the wear suffered by the tire and to allow the crumbling of tires of different diameters, «1 chopper roller also has a translation movement, which allows its position to be adjusted, guaranteeing the action of the blades on the surface of the tire until the end of the shredding process. The invention also contemplates the possibility of fixing the tire by inserting it into a rotating cylinder of suitable diameter, so that it rotates together with the cylinder but can move longitudinally through it, so that, by arranging the axis of the pick roller converging with that of the cylinder, the chopping of the tire progresses as it moves through the cylinder, thus allowing a continuous feeding of the chopping and crumbling process of the tire, since it is sufficient to introduce the tires through the initial end of the rotating cylinder so that they push each other until they are reached by the pick roller.
