Abstract

A plant (1) for transforming into secondary raw material, or disposing of, used tyres (P), made of rubber or other carbon matrices, comprises at least one pyrolysis chamber (6), wherein said used tyres (P) are subjected to pyrolysis 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), at least one hydraulic seal element (9) associated with said at least one supplying device (5) and heating means (16) for heating said at least one pyrolysis chamber (6). The 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 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). The 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 and an end portion (15) of the at least one supplying conduit (11), in contact with the at least one pyrolysis chamber (6), is made of thermally insulating material. The movable closing element (14) and the end portion (15) in thermally insulating material minimise the transmission of heat to the hydraulic seal element. Below an openable bottom (28) of the pyrolysis chamber (6) a hopper (22) is arranged that is suitable for conveying solid residual materials of the pyrolysis treatment to a shredding device (23), said hopper (22) being provided with pushing means (32) arranged for pushing to the shredding device (23) solid residues that accumulate on the walls of the hopper (22).
