DISPOSITIVO Y MÉTODO DE LIMPIEZA Y RECICLADO DE TÓNERES USADOSDEVICE AND METHOD OF CLEANING AND RECYCLING USED TONERS
El objeto de la presente invención es un dispositivo y un método de limpieza y reciclado de los tóneres de impresora láser ya empleados.The object of the present invention is a device and a method of cleaning and recycling of the laser printer toners already used.
Estado de la técnicaState of the art
En la actualidad no se conocen métodos efectivos para la limpieza y reciclado de los tóneres usados de impresora láser, una vez han sido usados y descartados. Ello, en parte, es debido a que no son residuos suficientemente significativos como para emplear recursos en su limpieza y reciclado, hasta el punto en que, actualmente, una de las formas más empleadas es el enterramiento del tóner, con los problemas medioambientales de toda índole que ello acarrea.At present there are no known effective methods for cleaning and recycling used laser printer toners, once they have been used and discarded. This, in part, is because they are not significant enough waste to use resources in cleaning and recycling, to the point that, currently, one of the most used forms is the burying of toner, with the environmental problems of all nature that this entails.
Otra solución empleada en la actualidad es emplear los sistemas de gestión de residuos electrónicos, pero estas instalaciones están generalmente refrigeradas con un gas como el nitrógeno que evita las deflagraciones. El problema de estas instalaciones para el bajo rendimiento en materias ricas que tienen los cartuchos de tóner, es muy caro, y por eso es necesario buscar una solución alternativa que no exigiera emplear gases ni tratarlos después.Another solution currently used is to use electronic waste management systems, but these facilities are generally cooled with a gas such as nitrogen that prevents deflagrations. The problem of these facilities for the low yield in rich materials that have the toner cartridges, is very expensive, and that is why it is necessary to look for an alternative solution that does not require to use gases or treat them later.
Además, las instalaciones de gestión de residuos electrónicos suelen ser plantas de varios cientos de metros cuadrados, cuyo empleo para el reciclado de tóneres no suele resultar rentable, dado que no es posible compatibilizar el uso de la planta de gestión para el reciclado de tóneres con la gestión y reciclaje de otros residuos de la industria electrónica.In addition, the electronic waste management facilities are usually plants of several hundred square meters, whose use for the recycling of toners is usually not profitable, since it is not possible to reconcile the use of the management plant for the recycling of toners with the management and recycling of other waste from the electronic industry.

Es un objeto de la presente invención proveer a la industria de un dispositivo y un método de limpieza y reciclado de tóneres usados que sea medioambientalmente sostenible y económicamente rentable. Todo ello de acuerdo con el dispositivo de la primera reivindicación que acompaña a la presente memoria descriptiva. En reivindicaciones dependientes se describen realizaciones particulares del dispositivo de la reivindicación primera. Por otro lado, en un segundo aspecto de la invención, se describe un método de limpieza y reciclado de tóneres usados que emplea el dispositivo descrito en la reivindicación primera.It is an object of the present invention to provide the industry with a device and method of cleaning and recycling of used toners that is environmentally sustainable and economically profitable. All this according to the device of the first claim accompanying the present specification. Dependent claims describe particular embodiments of the device of the first claim. On the other hand, in a second aspect of the invention, a cleaning and recycling method of used toners employed by the device described in claim one.
Así pues, la presente invención describe un sistema potente de aspiración para los polvos de tóner, que está magnetizado mediante partículas magnéticas que son las que hacen que precisamente la tinta pueda ser empleada en las impresoras láser. Es un objeto de la presente invención desmagnetizar previamente el polvo de tóner para su reciclado. Otro importante punto que hay que tener en cuenta de la presente invención es la protección anti-explosiones (ATEX) ya que el polvo de tóner tiende a deflagrar.Thus, the present invention describes a powerful aspiration system for toner powders, which is magnetized by magnetic particles which are precisely what makes the ink can be used in laser printers. It is an object of the present invention to pre-demagnetize the toner powder for recycling. Another important point to keep in mind of the present invention is the explosion protection (ATEX) since the toner powder tends to deflagrate.
