Definitions
- the present invention relates to a method for detecting and selectively separating metals from a quantity, in particular for separating non-ferrous and / or noble metals from other metals when recycling scrap, in particular electronic scrap.
- waste and scrap are a particularly big problem today.
- the waste often contains valuable raw materials that should be recovered in the event of appropriate recycling. This applies above all to waste / products that contain metals. Above all, the recovery of non-ferrous and precious metals is desirable.
- EP-A 0 125 435 describes a process for the treatment of metal parts provided with a surface coating described.
- the metal parts to be processed are crushed to a grain size of 1 mm to 20 mm, these coarse fractions are subjected to fine comminution in micro-vortex mills, on which the coarse fractions are crushed to a grain size of approximately 300 ⁇ m.
- the solid mixture of metal fraction and non-metal fraction in separators is then separated into the metal fraction and the non-metal fraction.
- the non-metal fraction is agglomerated and the metal fraction is removed for further processing.
- the present invention has for its object to provide a method of the above. To develop a way by which a metal fraction can be broken down even further. Above all, non-ferrous and / or precious metals should be removed from the metal fraction.
- This method is particularly applicable to non-ferrous and / or especially precious metals. It is known that gold components have a yellow or reddish color. In contrast, other metal parts, such as iron, are colored dark. According to the present method, the position of the yellow metal parts, ie of gold granules or gold-plated particles / granules, is determined, which are then separated out.
- the metal parts should first be crushed, for example ground and separated on a transport device before the detection.
- a conveyor belt is suitable, which is designed as a grid, the mesh size being smaller than the smallest diameter of the metal fraction.
- the invention also covers a device with devices for comminuting, grinding and separating metal components from other components.
- the device for separating the metal components is to be followed by a transport device which is assigned a device for detecting color differences in the metal components and which is connected to an ejector with the interposition of a computer.
- a line camera which works by optoelectronic means, is particularly suitable for the optical detection of the color differences of the metal parts.
- other options are also conceivable here.
- the separation of the detected metal parts of a certain color by means of the ejector can also be done in different ways. It is conceivable, for example, that a plurality of ejector nozzles are arranged under a grid-shaped conveyor belt, which blow off the metal parts detected. For this purpose the ejector is with connected to the line camera, the individual ejector nozzles being actuated by the line chamber depending on the position detection via a corresponding control.
- the metal particles could also run through sieve levels after the separation of other constituents and be separated depending on the size and / or weight.
- the individual sizes can then be placed on a corresponding frame with subdivisions, captured by the line scan camera and each frame can be fed individually to the ejector. Further possibilities are also conceivable here, which are intended to be included in the invention.
- the method according to the invention can be used above all in the recycling of metals, the present invention should not be restricted to this. According to the invention, it can always be used when a certain metal is to be separated from a quantity.
- this scrap 1 is comminuted in a first step.
- the shredding can take place, for example, in a shredder 2.
- the shredded amount reaches a mill 3, in which the scrap 1 is ground.
- a mill 3 in which the scrap 1 is ground.
- plastic components are separated from the metal particles.
- An impact mill, micro vortex mill or turbo mill is preferably used as the mill, in which the components to be ground collide. This effectively separates the plastic from the metal particles and simultaneously spheres the metal particles.
- the metal grains in the mill 3 preferably reach a diameter of 1 to 5 mm.
- Separator 4 can be used in any suitable device in which it is possible to separate the parts, in particular the plastic parts, from the metal parts. This also includes sieves, such as wind sifters or water tables. However, these are just examples.
- the separator 4 can be followed by sieve levels or similar separation devices, by means of which the metal parts are divided according to differently defined grain sizes or weights.
- the individual non-metallic components such as in particular plastic, are preferably discharged from the separator 4 through a discharge 5.
- the metallic components pass from an outlet 6 to a transport device 7.
- the metal components are then preferably separated on this transport device 7, as is indicated by way of example in FIG. 2.
- the transport device 7a according to FIG. 2 has a transport belt 8 which forms individual compartments 9 for metal balls 10.
- Metal balls 10a with a light coloring, in particular gold coloring, and dark metal balls 10b with dark coloring are indicated by way of example. These metal balls 10a and 10b are each located in a compartment 9 and are thus separated.
- the transport device 7 there is an optical detection device 11 by means of which color differences of the metal balls 10 can be detected.
- the position of these metal balls 10 is passed via a line 12 to a computer (not shown in more detail) and from there to an ejector 13, by means of which metal balls of a certain color are removed from the transport device 7. This can be done, for example, by blowing off or expelling.
- a computer not shown in more detail
- an ejector 13 by means of which metal balls of a certain color are removed from the transport device 7. This can be done, for example, by blowing off or expelling.
- FIG. 3 A mechanically operating ejector is shown in FIG. 3 as an example of an ejector 13a. This works with plungers 14 which push a metal ball 10a of a certain color through the conveyor belt 8, so that the metal ball 10a can fall into a receptacle 15. The metal balls 10b with a different color remain on the conveyor belt 8.
- the transport device 7a has a slot 16 in the region of a compartment 9.
- the conveyor belt 8 is so elastic that the slot 16 closes again after the metal ball 10 has been ejected.
