Abstract

In a linear magnetic separator using Foucault currents, the material processed is conveyed in a vibrating trough or belt arranged on the magnetic rotor, in the direction of the axis thereof, forcing the material to flow over the entire length of the magnetic rotor. The electroconducting particles are laterally deflected in that they are repelled by the Foucault currents generated in the material by the alternative magnetic field produced by the rotating rotor.

OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La invención, tal como se expresa en el enunciado de la presente memoria descriptiva, se refiere a un separador magnético lineal por corrientes de Foucault, que aporta a la función conocida de estos separadores, una serie de ventajas y características, aparte de las inherentes a su organización y constitución, que se describirán en detalle más adelante, que suponen una alternativa y/o mejora innovadora a lo ya conocido en este campo.The invention, as expressed in the statement of the present specification, refers to a linear magnetic separator by eddy currents, which provides the known function of these separators, a series of advantages and characteristics, apart from those inherent in its organization and constitution, which will be described in detail below, which represent an alternative and / or innovative improvement to what is already known in this field.
Más concretamente, el objeto de la invención consiste en un separador magnético de metales, por el principio de corrientes de Foucault, destinado a la separación de metales conductores eléctricos, aluminio, cobre etc., de entre un material no conductor eléctrico, especialmente en granulometria baja, en el que, ventajosamente y de forma caracterizadora, el rotor magnético se encuentra montado en linea con la dirección del movimiento del material a tratar, proporcionándole un notable aumento de su rendimiento.More specifically, the object of the invention consists of a magnetic metal separator, by the principle of eddy currents, intended for the separation of electrical conductive metals, aluminum, copper etc., from an electrical non-conductive material, especially in particle size low, in which, advantageously and characteristically, the magnetic rotor is mounted in line with the direction of movement of the material to be treated, providing a marked increase in its performance.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
En la actualidad y como referencia al estado de la técnica, debe mencionarse que la separación de pequeñas partículas de metales, tal como aluminio ó cobre en granulometrias bajas (0 a 3 m/m) con un separador magnético de corrientes de Foucault convencional, en el que el material es presentado por una banda sobre el rotor magnético, se realiza al lanzar el material conductor eléctrico en la misma dirección en la que llega el material, sacándolo de entre el material no conductor y siendo recogido por una clapeta separándolo del resto.At present and as a reference to the state of the art, it should be mentioned that the separation of small metal particles, such as aluminum or copper at low particle sizes (0 to 3 m / m) with a magnetic separator of eddy currents Conventional, in which the material is presented by a band on the magnetic rotor, is performed by throwing the electrical conductive material in the same direction in which the material arrives, removing it from the non-conductive material and being collected by a clapper separating it the rest.
El problema en partículas finas (inferior a 3 m/m) es la muy pequeña distancia a la que puede lanzarse estas partículas, ya que las corrientes de Foucault generadas en su masa, son de acuerdo con ésta, muy pequeñas .The problem in fine particles (less than 3 m / m) is the very small distance at which these particles can be thrown, since the eddy currents generated in their mass are, according to this, very small.
Por otra parte, en estas granulometrias, las partículas tienden a la forma esférica y las corrientes generadas en ellas tienden a girar a la partícula, reorientándose y evitando el efecto de lanzado.On the other hand, in these granulometries, the particles tend to the spherical shape and the currents generated in them tend to rotate to the particle, reorienting and avoiding the effect of throwing.
Se hace por tanto necesaria la creación de un separador magnético de este material de granulometria fina, de alto rendimiento, que de una solución adecuada a la problemática descrita, siendo éste el principal objetivo de la presente invención, sobre la cual, por otra parte, debe señalarse que, por parte del peticionario, se desconoce la existencia ninguna otra que presente unas características técnicas, estructurales y de configuración semejantes.It is therefore necessary to create a magnetic separator of this fine granulometry material, of high performance, that of a suitable solution to the problem described, this being the main objective of the present invention, on which, on the other hand, It should be noted that, on the part of the petitioner, the existence of any other that presents similar technical, structural and configuration characteristics is unknown.
EXPLICACIÓN DE LA INVENCIÓNEXPLANATION OF THE INVENTION
El separador magnético lineal por corrientes de Foucault que la invención propone, constituye por si solo una evidente novedad dentro de su campo, ya que a partir de su aplicación, se logra separar partículas de metales conductores eléctricos de solo unas pocas mieras de entre un material no conductor eléctrico con un elevado rendimiento.The linear magnetic separator by Foucault currents that the invention proposes, constitutes by itself an obvious novelty within its field, since from its application, it is possible to separate particles of electric conductive metals of only a few microns from an electrical non-conductive material with high performance.
La principal innovación que presenta el separador que la invención preconiza, consiste en presentar el material a tratar sobre el rotor en la dirección del eje de éste, todo lo contrario de lo hasta ahora conocido, en que el material a tratar se presenta en dirección perpendicular a la del eje del rotor.The main innovation presented by the separator that the invention advocates is to present the material to be treated on the rotor in the direction of its axis, quite the opposite of what has been known until now, in which the material to be treated is presented in the perpendicular direction. to that of the rotor shaft.
Para ello, el material es transportado mediante una banda, canaleta vibrante, plano inclinado, o elemento transportador alternativo, circulando por encima del rotor magnético en la misma dirección de su eje. Durante su recorrido, las pequeñas partículas de metal conductor son lanzadas en la dirección contraria al giro del rotor magnético y caen de nuevo sobre el transportador, quedando de nuevo sometidas al fuerte campo alterno generado por el rotor. De nuevo sufren un nuevo lanzado, repitiéndose sucesiva y rápidamente este efecto mientras continúan su transporte a lo largo del rotor.For this, the material is transported by a band, vibrating channel, inclined plane, or alternative conveyor element, circulating above the magnetic rotor in the same direction of its axis. During its journey, the small particles of conductive metal are thrown in the direction opposite to the rotation of the magnetic rotor and fall back onto the conveyor, again being subjected to the strong alternating field generated by the rotor. Again they suffer a new throwing, repeating this effect successively and quickly while they continue their transport along the rotor.
De esta forma, y dando suficiente longitud al rotor magnético, todas las partículas de metal conductor se trasladan sobre el transportador de forma lateral hasta ser evacuadas lateralmente, mientras que las partículas no conductoras eléctricas siguen sobre el transportador sin ser influenciadas por el mismo, siendo evacuadas al final del transportador.In this way, and giving sufficient length to the magnetic rotor, all the conductive metal particles are transferred on the conveyor laterally until they are evacuated laterally, while the non-conductive electrical particles remain on the conveyor without being influenced by it, being evacuated at the end of the conveyor.
Por otra parte, cabe destacar que las partículas de forma esférica que tienden a reorientarse, y que en un separador convencional fallarla muy frecuentemente el lanzado, en el de la invención giran sobre si mismas para reorientarse con el campo magnético de alta frecuencia. Esta rotación las hace rodar sobre el transportador en la misma dirección que la del lanzado y ser evacuadas igualmente por la canalización lateral, junto al resto de partículas de metal.On the other hand, it should be noted that the spherical particles that tend to reorient themselves, and that in a conventional separator, the thrown one frequently fails, in that of the invention they rotate on themselves to reorient themselves with the magnetic field high frequency This rotation causes them to roll on the conveyor in the same direction as that of the thrown and also be evacuated by the side channel, along with the rest of the metal particles.
El nuevo separador magnético lineal por corrientes de Foucault representa, por consiguiente, una estructura innovadora, de características estructurales y constitutivas desconocidas hasta ahora para tal fin, razones que unidas a su utilidad práctica, le dotan de fundamento suficiente para obtener el privilegio de exclusividad que se solicita.The new Foucault current linear magnetic separator represents, therefore, an innovative structure, with structural and constitutive characteristics unknown until now for this purpose, reasons that together with its practical utility, provide it with sufficient foundation to obtain the privilege of exclusivity that It is requested.

REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION
A la vista de las mencionadas figuras, y de acuerdo con la numeración adoptada, se puede observar en ellas un ejemplo de realización preferente del separador magnético lineal por corrientes de Foucault, el cual comprende las partes y elementos que se indican y describen en detalle a continuación.In view of the aforementioned figures, and according to the numbering adopted, an example of a preferred embodiment of the linear magnetic separator by eddy currents can be observed, which comprises the parts and elements indicated and described in detail to continuation.
Asi, tal como se aprecia en las figuras 2-A, 2-B y 2-C, el separador magnético lineal por corrientes de Foucault (1) que la invención preconiza está esencialmente constituido por una canaleta vibrante (2), fabricada en material no conductor eléctrico, tal como estratificado de vidrio, madera, etc., para que en ella no se produzcan calentamientos por efecto de corrientes de Foucault, sobre la que se alimenta el producto o material a tratar (m) por su extremo de entrada (3) .Thus, as can be seen in Figures 2-A, 2-B and 2-C, the linear magnetic separator by eddy currents (1) that the invention advocates is essentially constituted by a vibrating channel (2), made of material non-electric conductor, such as stratified glass, wood, etc., so that it does not produce heating due to eddy currents, on which the product is fed or material to be treated (m) by its inlet end (3).
Esta canaleta (2), mediante la acción de los vibradores rotativos (4) que incorpora, hace avanzar el material (m) sobre y en la dirección del eje (5) del rotor magnético (6), el cual se encuentra adecuadamente apoyado sobre los soportes de rodamientos (7) y que, por acción del motor (8), gira a altas revoluciones generalmente entre 1500 y 3000 revoluciones por minuto, estando para ello dispuesto, tal como se aprecia en dichas figuras, de forma que su eje (5) se encuentra orientado en la misma dirección en la que discurre el material a tratar sobre el elemento transportador o canaleta (2) .This channel (2), by means of the action of the rotary vibrators (4) that it incorporates, advances the material (m) on and in the direction of the axis (5) of the magnetic rotor (6), which is properly supported on the bearing supports (7) and which, by motor action (8), rotates at high revolutions generally between 1500 and 3000 revolutions per minute, being arranged, as shown in said figures, so that its axis ( 5) It is oriented in the same direction in which the material to be treated runs on the conveyor element (2).
El rotor magnético (6) está formado por numerosos polos longitudinales y de polaridad alterna, de forma que en la superficie de la canaleta vibranteThe magnetic rotor (6) is formed by numerous longitudinal and alternating polarity poles, so that on the surface of the vibrating channel
(2) se genera un muy alto campo magnético de elevada frecuencia que genera corrientes de Foucault en la masa de las partículas conductoras eléctricas (m' ) .(2) a very high magnetic field of high frequency is generated that generates eddy currents in the mass of the electrical conductive particles (m ').
Estas corrientes generan a su vez un campo magnético que se opone al del rotor (6), obligando a la partícula (m' ) a girar sobre si misma para reorientarse ó siendo lanzada ligeramente en la dirección contraria al giro del rotor (6) por repulsión.These currents in turn generate a magnetic field that opposes that of the rotor (6), forcing the particle (m ') to rotate on itself to be reoriented or being thrown slightly in the direction opposite to the rotation of the rotor (6) by repulsion.
La canaleta vibrante (2) dispone, tal como se aprecia en la figura 2-A en sección transversal, de una zona (2a) a un nivel más bajo, de recogida de las partículas metálicas (m' ) conductoras eléctricas, de forma que del material (m) que es transportado por la zona alta (2b) van saliendo las partículas conductoras (m' ) , bien rodando, ó bien con sucesivos y cortos lanzados hacia la zona (2a) de recogida donde caen y continúan su avance hacia el final de la canaleta vibrante (2) donde son recogidas selectivamente por una canalización o elemento de recogida al efecto (9), mientras que el resto del material no conductor eléctrico es recogido por una canalización o elemento de recogida (10) distinto.The vibrating channel (2) has, as shown in Figure 2-A in cross section, an area (2a) at a lower level, for collecting the electrically conductive metal particles (m '), so that of the material (m) that is transported by the high zone (2b) the conductive particles (m ') leave, either rolling, or with successive and short thrown towards the collection zone (2a) where they fall and they continue their progress towards the end of the vibrating gutter (2) where they are selectively collected by a channel or collection element for that purpose (9), while the rest of the non-conductive material is collected by a channel or collection element (10 ) different.
En las figuras 3-A, 3-B y 3-C se puede observar un ejemplo o variante alternativa del separador magnético lineal por corrientes de Foucault (1), en las que se aprecia como dicho separador (1) es esencialmente igual al anteriormente descrito y representado en las figuras 2-A, 2-B y 2-C, con la diferencia de que en este caso incorpora como elemento transportador una banda textil ó de goma (11) para la presentación del material (m) al rotor magnético (6) .In Figures 3-A, 3-B and 3-C an example or alternative variant of the linear magnetic separator by eddy currents (1) can be seen, in which it can be seen how said separator (1) is essentially the same as before described and represented in figures 2-A, 2-B and 2-C, with the difference that in this case it incorporates a textile or rubber band (11) for the presentation of the material (m) to the magnetic rotor (6).
En este caso, las partículas conductoras eléctricas (m' ) , que por efecto del rotor (6) son obligadas a desviarse, van abandonando la banda transportadora (11) lateralmente, siendo recogidas por un tolvin o encauzador lateral (12), mientras el resto de material avanza hasta el final de la cinta (11) .In this case, the electrical conductive particles (m '), which due to the rotor (6) are forced to deviate, leave the conveyor belt (11) laterally, being collected by a tolvin or lateral channeler (12), while the Other material advances to the end of the tape (11).
