Definitions

  • the invention regards an equipment that allows the detection, the acceleration along a well defined linear trajectory and the separation of not ferromagnetic metals, like the aluminium cans, from Municipal or Industrial solid wastes.
  • Municipal or Industrial solid wastes In particular municipal solid wastes contain important (from the economic point of view) quantity of not ferromagnetic metals, in particular Aluminium.
  • the not ferromagnetic metals can be detect using the eddy currents phenomenon generated by means of variable magnetic fields.
  • the combination of variable magnetic fields and the eddy currents generates on the not ferromagnetic metals the Lorentz Forces having a direction depending on the magnetic field direction. These forces are normally too small for permitting the separation of the not ferromagnetic metals from the other wastes. Only the use of magnetic field of extremely high intensity could permit the separation of the not ferromagnetic metals from the wastes which they are immersed in. In this case, the systems which produce the magnetic field require a very big electric power and consequently the energy electric consumption is tremendously high.
  • the invention seeks to overcome the previous mentioned difficulties providing an equipment which first detects the not ferromagnetic metals and after produces a very big forces on the metals, for a short instant of time, accelerating them in the same direction of the movement of the other wastes. The separation occurs when the wastes fall for gravity while the accelerated metals flight in a collection container.
  • this performance is accomplished :
  • the electric system producing the Lorentz forces on the not ferromagnetic metals acts as a three phase electric linear engine at induction.
  • the induced are the metals and the inductor are blocks of ferromagnetic metal sheets, shaped like a comb, and Copper windings lodged in each rabbet of the sheets , connected each other in such way that each block constitutes an inductor having ' p' poles and' n' phases.
  • An equipment of detection and separation of not ferromagnetic metals formed in accordance with the invention has a number of advantages.
  • the electric system producing the magnetic field is able to impress a very big force on the metal , moreover being nearly always switched off the electric energy consumption is very little and normally cooling system for the removal of effect Joule heating are not necessary. Therefore the income deriving from the recover of the separated metal overcome greatly the costs of the separation due to the low investment costs (induction electric engine technology is low cost and reliable) and low production costs.
  • the equipment is made up of:
