Definitions

  • the invention relates to a magnetic separator with a conveyor belt guided over a belt drum made of non-electrically conductive material for transporting the fraction to be sorted from more or less highly electrically conductive particles, with a magnet system which is rotatably driven in the belt drum at a higher rotational speed than that of the belt drum and with behind the belt drum arranged collection container for the separated electrically conductive particles.
  • Such a device is known from US Pat. No. 3,448,857.
  • a magnetic system arranged in a drum rotates within the belt drum at a speed of approximately 1500 rpm, while the conveyor belt carries the fraction to be sorted at a speed of 1 m / sec to 1.5 m / sec of the belt drum and thus feeds the magnet system.
  • the drum in which the magnet system is arranged has an outer diameter which corresponds approximately to the inner diameter of the belt drum, and a small, constant air gap is formed between the magnet system and the belt drum.
  • a ferromagnetic particle can get between the conveyor belt and its belt drum. It is also possible that such a particle can get through a wear point in a conveyor belt between the belt drum and the conveyor belt. These ferromagnetic particles are held in place by the magnetic force and circulate on the belt drum.
  • the belt drum In order not to impair the effect of the magnet system, the belt drum must be made of non-conductive material. As a rule, the belt drum of such a system is made of plastic. However, this plastic material will already melt at relatively low temperatures.
  • a magnetizable electrically conductive particle, i.e. Iron particles, which have settled between the conveyor belt and the belt drum, are warmed up so strongly by the alternating magnetic field of the magnet system that they begin to glow.
  • the particle can work its way through the plastic of the belt drum and enters the air gap between the outer surface of the magnet system and the inner surface of the belt drum.
  • the device may then be severely damaged under certain circumstances, since the rapidly rotating magnetic system takes the iron particles with it and, for example, slits the belt drum jacket. This entails a system shutdown and an expensive repair.
  • the invention has for its object to provide a generic magnetic separator in such a way that damage to the belt drum by particles between the conveyor belt and belt drum are avoided.
  • This object is achieved in that the outer diameter of the magnet system is significantly smaller than the inside diameter of the belt drum and that Magnet system is arranged eccentrically in the belt drum.
  • an iron particle gets between the belt drum and the belt, it is clamped between the belt drum and the belt and thereby initially guided past the rapidly rotating magnet system, but it cannot be held by it, but it is forced to rotate Belt drum placed at a greater distance from the magnet system.
  • the influence of the magnetic lines of force on the iron particle is so small that it either gets stuck on the belt drum or falls on the lower run of the conveyor belt.
  • Strippers are preferably arranged on the outside of the belt drum between the upper and lower runs of the conveyor belt and / or on the inside of the lower run of the conveyor belt behind the belt drum, so that iron particles passing between the conveyor belt and the belt drum are stripped from the belt drum or the lower run of the conveyor belt and can be derived. This prevents damage to the belt drum caused by the trapped iron particles.
  • the magnet system can be pivoted about the center of the belt drum, so that the relative position between the magnet system and the belt drum can be adjusted with simple means and, for example, maintenance work can be facilitated.
  • the air gap between the drum shell and the magnet system is preferably adjustable.
  • the diameter of the magnet system is preferably approximately half the diameter of the belt drum, so that the magnet system can be pivoted through 360 ° around the center of the belt drum.
  • the magnet system can consist of permanent or electromagnets.
  • the figure shows a conveyor belt 10 which is guided over a belt drum 12.
  • a fraction of more or less electrically conductive particles 16 is arranged, which are transported at a speed of about 1 m / sec to 1.5 m / sec in the direction of arrow 18 on the conveyor belt 10.
  • the belt drum 12 consists of electrically non-conductive material, for example a plastic material.
  • the cylinder drum 24 of the magnet system 20 has approximately half the diameter of the belt drum 12.
  • the center 26 of the cylinder drum 24 is arranged eccentrically to the center 28 of the belt drum 12.
  • the cylinder drum 24 can be pivoted with the magnets 22 by means of arms 30 about the center 28 of the belt drum 12.
  • the magnet system 20 is arranged in the position shown in the figure in order to optimally separate particles which are good electrical conductors from particles which are less electrically conductive.
  • the magnet system 20 rotates around the center point 26 at a speed of approximately 1500 rpm.
  • the container 32 In front of the belt drum 12 there is a container 32 into which the electrically conductive particles 34 fall.
  • the magnetic lines of force of the magnet system 20 cut through the belt drum 12 and the conveyor belt 10 and the electrically conductive particles 16 indicated on the conveyor belt.
  • currents are induced in the electrically conductive particles, which are higher in the case of well electrically conductive particles than less conductive particles.
  • the particles with good electrical conductivity are then accelerated onto a throwing path, which is indicated by arrow 36. The less conductive particles remain near the conveyor belt and fall down between it and the container 32.
  • An air gap 38 is formed between the outer surface of the cylinder drum 24 of the magnet system 20 and the inner surface of the belt drum 12, which air gap 38 changes continuously due to the eccentric arrangement of the magnet system 20 in the belt drum 12.
  • a wiper 40 and a collecting container 42 underneath are arranged on the outer surface of the belt drum 12 opposite to the magnet system 20 arranged in the belt drum 12.
  • Another scraper 44 is provided on the inner surface of the lower run 46 of the conveyor belt 10.
  • the air gap 38 between the belt drum 12 and the magnet system 20 is continuously adjustable by moving the center 26 of the magnet system 20 along the elongated hole 50 of the arm 30.
  • an iron particle 48 gets between the inside of the conveyor belt 10 and the outside of the drum 12, a current is induced in it by the action of the magnetic lines of force of the magnetic field 20 and the iron particle 48 becomes due to the high speed of rotation of the magnet system 20 entrained on the outer surface of the belt drum 12 until after sufficient rotation of the belt drum 12 the distance of the iron particle 48 arranged on the outer surface to the magnet system 20 becomes so great that the magnetic lines of force lose their influence on the iron particle 48. If the iron particle 48 remains stuck to the belt drum 12, it can be stripped off by the scraper 40 and released into the collecting container 42.
  • the particle falls beforehand from the outer surface of the belt drum 12 onto the lower strand 46, it will become from the scraper 44 removed from the space between the upper and lower run of the conveyor belt 10.
  • the eccentric arrangement of the magnet system 20 in the belt drum 12 and due to the smaller diameter of the magnet system 20 prevent an iron particle 48 between the belt drum 12 and the conveyor belt 10 from being entrained by the magnet system at a higher speed than the belt drum 12, so that since the iron particle 48 does not undergo very great heating due to the influence of the magnet system 20, damage to the belt drum 12, that is to say, for example, a slitting thereof by the iron particle 48 is excluded.
