Abstract
Plant (1) for transforming into raw 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), said plant (1) comprising at least one hydraulic seal element (9) associated with said at least one supplying device (5) and heating means (16) for 10 heating said at least one pyrolysis chamber (6), characterised in that 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 at least one supplying conduit (11) that extends prevalently vertically until it reaches an inlet zone (12) of the at least 15 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 an inlet opening (13). 2. Plant (1) according to claim 1, characterised in that it comprises a plurality of pyrolysis chambers (6) each of which is supplied with said tyres (P) by means of a 20 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 conduit (11). 3. Plant (1) according to claim 1, or 2, wherein said at least one supplying conduit (11) extends vertically over a length of at least 4 metres, in particular over a length 25 comprised between 4 and 20 metres. 4. Plant (1) according to any preceding claim, wherein said second conveying device comprises a rung conveyor (7). 5. 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. 30 6. Plant (1) according to any preceding claim, wherein said inlet opening (13) is provided with a movable closing element (14), that can rotate around a hinge element (16) between a closed position and an open position.7. Plant (1) according to claim 6, wherein said movable closing element (14) is coated with a thermally insulating material. 8. Plant (1) according to claim 6, or 7, further comprising an actuator (36) suitable for driving said movable closing element in such a manner that it rotates around said hinge 5 element (16). 9. Plant (1) according to any preceding claim, wherein an end portion (15) of the at least one supplying conduit (11), in contact with said at least one pyrolysis chamber (6), is made of a thermally insulating material.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
