Definitions
- the present invention relates to a method and a device for ensuring the separation and recovery of metallic constituents and / or other recoverable constituents present in a composite material, in particular plastic-metal laminate.
- the invention applies in particular, without being limited to such an application, to the recovery of copper contained in laminate plates for printed circuits.
- laminate plates for printed circuits consisting of a glass fabric support bonded by epoxy resins on which is deposited a coating of copper of very high purity, it is necessary to cut to the desired format of relatively large plates significant, which results in falls comprising a significant proportion of very high purity copper (of the order of 99.95%).
- very high purity copper of the order of 99.95%).
- the present invention has set itself the objective of carrying out the separation of metallic compounds and in particular copper, contained in a composite material by means of a process which does not have the drawbacks mentioned above of the prior techniques.
- the invention relates to a process for separating recoverable metal constituents such as in particular glass-resin-metal contained in a composite material, in particular plastic-metal laminate, characterized in that it consists in:
- the atmosphere controlled during the heat treatment can be oxidizing or reducing.
- the temperature of this heat treatment is approximately 400 ° C.
- the invention also relates to a device for implementing the method as specified above.
- a heat treatment chamber supplied with waste of composite material and in which the pyrolysis of this waste is carried out at a temperature between 350 and 450 ° C, preferably about 400 ° C, the combustion gases of the binders contained in the material composite being evacuated from said enclosure to be treated and purified by conventional means;
- - grinding means receiving the material from the heat treatment enclosure; - means ensuring the separation of recoverable metal constituents from the by-products and;
- said heat treatment enclosure is produced in the form of an enclosure with heat transfer particles, which may for example be of the particle rain, fluidized bed or vibrated bed type.
- the waste of said composite material previously reduced to the necessary dimensions is brought on a continuous conveyor of various types, carpet, vibrator, etc. and in this case a rotary drum positioned in said heat treatment enclosure and more particularly in the bed of particles, the feeding of said drum being carried out using a feed screw placed at one of its ends and the extraction and evacuation of the treated waste being carried out using a system conventional lifter provided at the other end of said drum.
- this process is essentially characterized by the fact that the waste of composite material containing a recoverable metallic constituent, in particular a red metal such as copper, is treated in a heat treatment enclosure. in which is maintained a temperature between 350 and 450 ° C, preferably 400 ° C, a controlled atmosphere being maintained in said enclosure so as to avoid any ignition of the products resulting from the combustion of flammable materials.
- a recoverable metallic constituent in particular a red metal such as copper
- the treated material undergoes a sorting operation in order to separate the recoverable metal component, the latter then being conditioned.
- the single figure represents, by way of nonlimiting example an installation making it possible to ensure the implementation of the method according to the invention.
- This installation comprises a feed hopper 10 in which the waste of the composite material is stored (for example waste resulting from the cutting of printed circuit boards), these having been previously conditioned, for example by cutting them to the desired dimensions.
- This hopper 10 feeds, by means of conventional dosing and weighing devices not shown in the drawing, the heat treatment chamber 12 in which a temperature between about 350 and 450 ° C. is maintained as well as a controlled atmosphere can be oxidizing or reducing.
- This "heat treatment chamber 12 is preferably a particle oven, for example a fluidized bed, vibrated bed or particle rain oven.
- the waste coming from the hopper of storage 10 are brought to a conveyor and, in this case in a rotary drum placed in the particle bed, the feeding of this drum being carried out by any conventional means, in particular a conveyor screw placed at one end of said drum and the treated waste is removed using conventional lifting systems positioned at the other end of this drum.
- a conveyor screw placed at one end of said drum and the treated waste is removed using conventional lifting systems positioned at the other end of this drum.
- the treated waste coming from the furnace 12 is brought into a hopper 14 supplying a crusher 16 from which this treated waste and reduced to the desired dimensions is
- the valuable metal components are fed into a scrubber 26 to be subsequently stored after treatment in a hopper 28 feeding a packaging installation 5 30.
- This conditioning can be performed so as to perform a compacting granulation of the recovered metallic component which is then packaged and evacuated.
- the installation naturally includes conventional means for purifying and dedusting the fumes extracted from the pyrolysis furnace 12 (these installations of well known type have not been shown in the drawing). It also includes a system for purifying and filtering the air from the separator 18 and the purifier 26. Here still these are systems well known to those skilled in the art and for this reason, they will not be described here.
- the invention allows under particularly advantageous economic conditions to recover metallic components of high purity contained in composite materials, in particular plastic-metal laminates. This is how this invention makes it possible to recover the copper contained in waste originating from the production of printed circuit boards.
