Abstract
Plant (1) for transforming into raw and secondary material, or disposing of, used tyres (P), made of rubber or other carbon matrices, comprising at least one pyrolysis chamber (6), wherein said used tyres (P) are subjected to pyrolysis 5 treatment, said tyres (P) being conveyed to said at least one pyrolysis chamber (6) by means of at least one supplying device (5) that receives the tyres (P) from a first conveying device (3) and conveys the tyres (P) to said at least one pyrolysis chamber, said plant (1) comprising at least one hydraulic seal element (9) associated with said at 10 least one supplying device (5) and heating means (16) for heating said at least one pyrolysis chamber (6), characterised in that it comprises at least one supplying conduit (11) through which said tyres (P) are conveyed, said at least one supplying conduit mainly extending vertically and being interposed between said at least one hydraulic seal element (9) and said at least one pyrolysis chamber (6), an end 15 portion (15) of said at least one supplying conduit (11), in contact with said at least one pyrolysis chamber (6), being made of a thermally insulating material. 2. Plant (1) according to claim 1, wherein said at least one supplying conduit (11) communicates with an inlet opening (13) of said at least one pyrolysis chamber, said inlet opening (13) being provided with a movable closing element (14) coated 20 with thermally insulating material. 3. Plant (1) according to claim 2, wherein said movable closing element (14) can rotate around a hinge element (16) between a closed position and an open position. 4. Plant (1) according to claim 3, further comprising an actuator (36) suitable for driving said movable closing element (14) so that it rotates around said hinge 25 element (16). 5. Plant according to any one of claims 2 to 4, wherein said at least one supplying device (5) comprises a second conveying device (7) that receives the tyres (P) from the first conveying device (3) and conveys the tyres (P) through said at least one hydraulic seal element (9) and along said at least one supplying conduit (11) until 30 reaching an inlet zone (12) of the at least one pyrolysis chamber (6), where said tyres (P) are released by said second conveying device (7) and drop by gravity into said pyrolysis chamber (6) through said inlet opening (13). Plant (1) according to claim 1, or 2, characterised in that it comprises a plurality of pyrolysis chambers (6) each of which is supplied with said tyres (P) by means of a respective supplying device (5), that receives the tyres (P) from the first conveying device (3) and conveys the tyres (P) to a respective pyrolysis chamber (6) through a respective supplying 5 conduit (11). 7. Plant (1) according to any preceding claim, wherein said at least one supplying conduit (11) extends vertically over a length of at least 4 metres, in particular over a length comprised between 4 and 20 metres. 8. Plant (1) according to any preceding claim, wherein said second conveying device 10 comprises a rung conveyor (7). 9. Plant (1) according to any preceding claim, wherein said at least one hydraulic seal element (9) comprises a tank (10) containing a liquid (L), in particular water or oil.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
