Definitions

  • the invention relates to a device for separating non-magnetizable metals, in particular non-ferrous metals, from a solid mixture with an alternating magnetic field generator and with a crown plate which protrudes between the throwing parabolas of the deflected non-ferrous metal flow on the one hand and the flow of the remaining solid mixture on the other hand.
  • the so-called eddy current separation can be carried out with the aid of such a device.
  • the feed material is guided over the poles of an alternating magnetic field generator, for example on a belt or in free fall.
  • eddy currents are induced in the electrically conductive constituents of the mixture to be separated, which build up their own magnetic fields which are opposed to the generating field and thereby accelerate these constituents by electromagnetic forces relative to the other constituents of the mixture.
  • Eddy current separation can be used to separate non-ferromagnetic, highly electrically conductive substances, such as aluminum and copper, from non-ferrous solid mixtures and non-ferrous metal / non-metallic solid mixtures, such as automobile shredder rubble, electronic scrap and the like. If This material contains ferromagnetic parts, the eddy current separation can be preceded by a magnetic separation in order to remove ferromagnetic parts beforehand. It is also advisable to precede the eddy current separation with other sorting and classifying stages because the greatest possible pre-enrichment and fractionation of the feed material has a positive effect on the separation success.
  • a solid mixture for separating the ferromagnetic portion is first passed under a magnetic separator by means of a conveyor belt and then fed from the conveyor belt to a preferably slowly rotating outer drum for separating the non-ferrous metals.
  • a fast rotating rotor equipped with permanent magnets is arranged concentrically inside the outer drum. The permanent magnets extend uniformly along the axis of rotation of the magnetic rotor and are arranged there at a large distance from one another in order to ensure that a magnetic field which forms between the poles of the permanent magnets acts as far as possible outside the drum.
  • the solid mixture reaches the area of the alternating magnetic field very early, namely before the upper vertex of the outer drum.
  • the non-ferrous metal parts are thus additionally accelerated very early, essentially tangentially in the conveying direction. These parts therefore pass into a throwing parabola much earlier than the non-conductive material parts, ie they lose contact with the drum at an early stage.
  • Separate removal of the non-ferrous metal components and other constituents is to be supported by means of a separating saddle, which faces the mixture components deflected by the alternating magnetic field to different ejection parabolas and is arranged directly above the collecting containers located under the magnetic rotor in the area of the already separated material flows.
  • the acceleration of the non-ferrous metal parts is not sufficient to deflect the throwing parabola, which begins at the apex of the drum, far enough beyond the drum radius. It is therefore not possible to rule out disabilities with the electrically non-conductive parts which are either still lying on the drum surface or are being detached due to gravity.
  • the non-ferrous metal parts already detached at the apex of the drum due to the force of the magnetic field rather hit the electrically non-conductive parts conveyed by the outer drum, so that mutual hindrances occur.
  • conductive parts to be deflected are braked by the non-conductive parts and, on the other hand, non-conductive parts are undesirably accelerated by contact with the conductive non-ferrous metal parts. As a result, incorrect discharges cannot be avoided in both grades, ie electrically non-conductive parts also get into the collection area of the non-ferrous metal parts and vice versa.
  • US Pat. No. 3,448 also describes a device for separating materials that are less electrically conductive from electrically well conductive by means of a magnetic rotor arranged concentrically in a rotating outer drum, the magnets of which are arranged alternately with a north and a south pole on the periphery of the rotor body 857 became known.
  • the solid mixture intended for separating the constituents is fed to the outer drum of the magnetic rotor either from a belt conveyor running a short distance above the outer drum or by means of a conveyor belt which wraps around the outer drum.
  • the magnetic forces accelerate the electrically highly conductive substances to a more distant trajectory than the electrically less highly conductive substances, so that these components can be separated due to the different trajectories.
  • the invention has for its object to provide a device of the type mentioned, which allows a better separation of non-ferrous metals from a solid mixture containing in particular small and / or light, flat components.
  • this object is achieved in that the top of the apex plate ends near the material discharge area in the discharge sector.
  • an alternating magnetic field generator which is, for example, a rotating body
  • the upper edge should lie above the horizontal central plane running through the axis of rotation of the rotating body.
  • the invention is based on the knowledge confirmed by numerous tests that, in particular in the case of solid mixtures with small non-ferrous constituents (fractions ⁇ 15 mm) or larger, flat, but also light material, such as used for condenser paper, with aluminum vapor-deposited foils, a sailing effect of these parts occurs. Due to the low mass, such non-ferrous components are only slightly repelled by the eddy current effect of the alternating magnetic field. Because of the low weight and the often flat shape of these particles, these particles float (sail) more or less when falling, and the valuable and the less valuable components mix again and again below the material discharge area of the alternating magnetic field generator.
  • material discharge area is understood to mean the area in the discharge sector in which the full force of either an inductive, but preferably of an alternating magnetic field generated by the magnetic rotor floods the non-ferrous metals.
  • the discharge sector is a quadrant which is delimited by a horizontal and a vertical and essentially comprises the entire area of the alternating magnetic field generator which actively acts on the feed material.
  • the material discharge area is defined where the material to be separated is advantageously at least advantageously on the slideway, which is either curved from the circular shape or formed as a stationary or rotating drum, or by a driven conveyor belt that wraps around the slideway or drum, or from one of the alternating magnetic field generators Curved line formed in the ejection sector surrounding the slider, due to gravity just slipping or falling, so that the greatest deflection of the throwing parabola results in the combination of the mechanical ejection forces with the repulsive forces of the magnetic field which act as late as possible for the non-ferrous metals.
  • the crown plate ends only a little away from the outer surface of the slideway in the material discharge area. This further improves the quality of the separation of the mixture constituents.
  • the separation quality is also optimized if the top edge of the crown plate runs above the narrowest point of the gap formed between the alternating magnetic field generator and the inner surface of the slideway.
  • a cutting-like upper edge that is achieved in this way which can be wedge-shaped, for example, favors the directing of the valuable mixture components onto the in Direction of conveyance rear surface of the crown plate and from there selectively into the corresponding collecting container or into a stationary collecting chamber. It results for elongated mixture components, such as for wire, a function like a long section separator, since these long components can be supported on the surface of the conveyor belt or the slideway / drum and the crown plate, so that they are in this way over move the distance of the top edge away from the surface formed.
  • the crown plate is designed with an arcuate and / or oblique course, so that it extends with its lower end from a position further forward in the conveying direction, starting from the installation level, in the direction of the alternating magnetic field generator, it can be achieved that that at least the same width as the alternating magnetic field generator crest plate completely seals off the lower collecting chambers for valuable and non-valuable components. There is therefore only the gap due to the distance that the upper edge of the crown plate takes from the surface of the conveyor belt, the slideway or the drum.
  • the valuable components deflected onto a larger discharge parabola are in this way - also supported by the inclined course of the crown plate - directed specifically to the collecting chamber arranged on the side of the crown plate facing away from the alternating magnetic field generator or to a collecting container set up there.
  • the distance of the upper edge from the surface of the conveyor belt, the slideway or the drum can be changed; at for a feed with changing mixture components, the gap to be passed by the less valuable components can be increased or decreased accordingly.
  • the crown plate is combined with a separating saddle and the separation saddle is advantageously in several pieces and consists of a lower saddle and a support pivotably arranged thereon, the crown plate can preferably be attached to the support with a fork piece.
  • the crown plate can then be pivoted by means of the carrier and can be removed very quickly and easily due to the plug connection, for example when the feed material contains components which, due to their size and / or weight, do not give rise to the mentioned sailing effect.
  • the crown plate could also be arranged in a suspension, which can consist, for example, of adjusting rods or cylinders and would have to be accommodated inside a discharge box that shields the discharge sector from the outside, although the suspension could then be damaged by the materials and also the free access to the drop box disabled.
  • a suspension can consist, for example, of adjusting rods or cylinders and would have to be accommodated inside a discharge box that shields the discharge sector from the outside, although the suspension could then be damaged by the materials and also the free access to the drop box disabled.
  • a crown plate composed of at least two parts, at least the upper part of the crown plate removed from the lower saddle advantageously being made of an electrically non-conductive material. Materials such as wood, ceramic or plastic are suitable for the upper part of the crown plate.
  • An at least two-part crown plate allows only this part of the plate to be replaced by a replacement part in the event of wear, in particular the chamfered upper edge.
  • the carrier be connected to a preferably lockable pivot lever.
  • the swivel lever arranged laterally outside the discharge box is freely accessible to an operator; after adjusting the swivel lever and thus the carrier with the crown plate attached, the swivel lever is fixed in its set position, for which a clamping lever or a wing nut can be used.
  • Exceeding or falling below a limit dimension for the width of the gap between the top edge of the crown plate and the opposite surface can advantageously be prevented by means of stops defining the end positions of the pivoting lever.
  • the swivel lever can be freely arranged and provided with taring.
  • the free mobility offers the advantage that the dividing saddle with the top plate can escape in the conveying direction in the case of mixture components that could jam in the gap and thus clear the way; Bridge formation is thus largely avoided.
  • the buoyancy for example a weight that is slidably arranged on a bolt connected to the pivot lever, or a tension spring, engages the pivot lever from the rear in the conveying direction and, on the one hand, ensures a certain stiffness and inertia, so that the pivot lever is not so easy escapes from its operating position, and on the other hand ensures that the pivoting lever moves back into its operating position after the mixture components causing the deflection of the crown plate have passed through the gap.
  • the separating saddle be horizontally adjustable. Before the alternating magnetic field generator is put into operation, the separating saddle can be preset according to the composition of the mixture components of the feed material to be processed, and thus the guidance of the separated mixture components into the associated collecting chambers for valuable and less valuable mixture components can be supported.
  • the separating saddle can be arranged in a subchamber that can be moved in sliding pieces.
  • the sliders can advantageously be arranged on strips which are attached to a discharge box downstream of the alternating magnetic field generator in the conveying direction.
  • the sliders can be, for example, U-profiles placed on the strips. Since the strips are not arranged inside, but outside the drop box, for example welded there to the side walls, the separation of the mixture components, and also the accessibility of the inside of the drop box necessary for maintenance purposes, is not impaired.
  • the horizontal adjustment can be achieved by changing the angular position of the adjustment levers relative to one another.
  • the sliders can advantageously be screwed onto the strips; an unintentional horizontal adjustment during operation is excluded.
  • a solid mixture containing nonferrous metals is placed on a vibrating trough 1 designed as a feed conveyor according to FIG. 1.
  • the feed material is made more uniform in height and width on the vibrating trough 1, which supports the later separation of the mixture components.
  • the vibrating trough 1 inclined in the conveying direction 2 discharges the mixture from a low height onto a conveyor belt 3.

  • the speed of the conveyor belt 3 is greater than the conveying speed of the vibrating trough 1, so that the layer height of the mixture is further reduced by the single-layer achieved on transfer to the conveyor belt 3.
  • a magnet rotor 6 is arranged eccentrically in the drum 5 and has rows of permanent magnets (not shown) which extend in the longitudinal direction of the rotor shaft and are fastened in the base body with alternating north-south polarity. Such an arrangement is shown and described in the earlier EP application 89104611.2.
  • the axis of rotation 7 and thus the magnet rotor 6 are to be adjusted concentrically on a radius around the drum axis of rotation 8 and radially (cf. FIG. 2).
  • the effective range of the magnetic rotor 6 can be adjusted in a discharge sector 11 delimited by the vertical 9 and horizontal 10 passing through the axis of rotation 8 of the drum 5, in which the material discharge region 13 lies, in which the mixture lying on the conveyor belt 3 due to the effective force of the eddy currents and / or gravity slides or falls.
