Descripción de la invenciónDescription of the invention

El procedimiento y el dispositivo para la separación de metales no ferrosos en manipulación de materiales al por mayor, objeto de esta invención, presentan unas particularidades técnicas destinadas a ofrecer un funcionamiento mejorado y un tamaño de la instalación más compacta y económica.The procedure and the device for separation of non-ferrous metals in material handling at wholesale, object of this invention, have particularities techniques designed to offer improved performance and size of the most compact and economical installation.

Según la invención esto se soluciona por las características de la reivindicación principal. Otras reivindicaciones se refieren a las formas ventajosas de la invención.According to the invention this is solved by characteristics of the main claim. Other claims refer to the advantageous forms of the invention.

La ventaja principal de la invención es hacer de dos máquinas sólo una máquina por la combinación de la simple y probada técnica de sensor electromagnético y la tecnología de corriente de remolino (corrientes de Foucault). Esto permite no sólo una inversión bastante baja, sino que al mismo tiempo la reducción de una planta de clasificación bastante compleja a una compacta.The main advantage of the invention is to make two machines just one machine by combining the simple and Proven electromagnetic sensor technique and technology eddy current (eddy currents). This allows not only  a fairly low investment, but at the same time the reduction from a fairly complex sorting plant to a compact

En cuanto al mencionado proceso anterior el "SCS Sensor Current Separator" o sensor separador de corriente SCS está colocado detrás de una unidad de trituración, seguida de un separador de imán, o colocado directamente detrás de una criba y separador magnético. Las fracciones de entrada se alimentan en la cinta transportadora del dispositivo "SCS" vía una banda transportadora con un alimentador vibrador.As for the above mentioned process the "SCS Sensor Current Separator" or current separator sensor SCS is placed behind a crushing unit, followed by a magnet separator, or placed directly behind a sieve and magnetic separator. The input fractions are fed into the conveyor belt of the "SCS" device via a belt Conveyor with a vibrating feeder.

El reconocimiento selectivo del metal ocurre al principio de la banda transportadora mediante sensores electromagnéticos. Poco después, la corriente de material pasa hacia el final de la cinta donde las corrientes de remolino son generadas al paso de metales no ferrosos haciéndoles saltar lejos de la corriente de material del principio.Selective metal recognition occurs at principle of the conveyor belt by sensors electromagnetic Shortly after, the flow of material passes to the end of the belt where the eddy currents are generated to the passage of non-ferrous metals making them jump away from the material stream from the beginning.

Debajo del extremo de la cinta se encuentra una bandeja separadora que separa los metales no ferrosos que saltan de la corriente de material restante por el efecto de las corrientes de remolino. Los metales restantes, tales como el acero inoxidable, que todavía están contenidos en el material, han sido anteriormente detectados por los sensores electromagnéticos citados y ahora pueden ser expulsados por unos inyectores de aire colocados en la mencionada bandeja de separación.Under the end of the tape is a separating tray that separates non-ferrous metals that jump from the material stream remaining by the effect of the streams of swirl. The remaining metals, such as stainless steel, which they are still contained in the material, they have been previously detected by the aforementioned electromagnetic sensors and can now be ejected by some air injectors placed in the mentioned separation tray.

Una segunda bandeja de separación, separa del material restante una tercera corriente de producto que principalmente consiste en acero inoxidable.A second separation tray separates from the material remaining a third product stream that It mainly consists of stainless steel.

Como es imposible decir exactamente de antemano cuál de los metales inductivos reaccionaría suficientemente a las corrientes de remolino para saltar lo bastante lejos y alcanzar la bandeja de separación, el sensor metálico debe ser adaptado a los metales que no pueden ser suficientemente inducidos por las corrientes de remolino. Esto se refiere al acero inoxidable. Por consiguiente, se crea una tercera corriente de producto concentrada, consistente principalmente en acero inoxidable.How impossible to say exactly beforehand which of the inductive metals would react sufficiently to the eddy currents to jump far enough and reach the separation tray, the metal sensor must be adapted to the metals that cannot be sufficiently induced by eddy currents This refers to stainless steel. By consequently, a third stream of concentrated product is created, consisting mainly of stainless steel.

Para la combinación del separador de corriente de remolino con el sensor o sensores metálicos, la presente invención permite la producción de fracciones de metal de altas cualidades no ferrosas y otros materiales valiosos con un medio simple y de un modo económico. La combinación de numerosos sensores y unidades de separación reduce considerablemente el tamaño de la planta y -distintamente a las máquinas de clasificación comunes- se producen más de dos fracciones clasificadas. Esto causa una reducción de gastos para la construcción de la máquina y la planta. Las ventajas económicas son el resultado de las exigencias de tiempo reducido para la clasificación cualitativa del material de entrada.For the combination of the current separator swirling with the metal sensor or sensors, this invention allows the production of high metal fractions non-ferrous qualities and other valuable materials with a medium Simple and in an economical way. The combination of numerous sensors and separation units greatly reduces the size of the plant and - differently from the common sorting machines - are produce more than two classified fractions.
