Abstract

Przedmiotem zgłoszenia jest sposób recyklingu rur wielowarstwowych i urządzenie do recyklingu rur wielowarstwowych. Sposób recyklingu rur wielowarstwowych polegający na oddzieleniu warstwy metalowej od warstw z tworzywa sztucznego poprzez cięcie rury wielowarstwowej (R), podgrzanie jej i odkształcenie plastyczne charakteryzuje się tym, że rurę wielowarstwową (R) umieszcza się w urządzeniu podawczym (6), a następnie rozcina się wzdłużnie na całej jej długości na grubość ścianki w mechanizmie tnącym (7), po czym podgrzewa się do momentu roztopienia kleju w zespole podgrzewającym (8) i formuje się w mechanizmie walcującym (9) rozciętą rurę wielowarstwową (R) do postaci taśmy (T), walcując przy tym utworzoną taśmę (T) do grubości mniejszej niż grubość ścianki (S) rury wielowarstwowej (R). Urządzenie do recyklingu rur wielowarstwowych zawierające mechanizm tnący (7), zespół podgrzewający (8), mechanizm walcujący (9) charakteryzuje się tym, że zawiera mechanizm podawczy (6), za którym znajduje się mechanizm tnący (7) z nożem wysuniętym powyżej grubość ścianki rury wielowarstwowej (R), zaś w mechanizmie walcującym (9) przy każdym z walców zamocowane są skrobaki.The subject of the application is a method of recycling multilayer pipes and a device for recycling multilayer pipes. The method of recycling multilayer pipes consisting in separating the metal layer from the plastic layers by cutting the multilayer pipe (R), heating it and plastically deforming it is characterized in that the multilayer pipe (R) is placed in a feeding device (6), and then cut longitudinally along its entire length to the wall thickness in a cutting mechanism (7), after which it is heated until the adhesive melts in a heating unit (8) and the cut multilayer pipe (R) is formed in a rolling mechanism (9) into a tape (T), while rolling the formed tape (T) to a thickness less than the wall thickness (S) of the multilayer pipe (R). A device for recycling multilayer pipes comprising a cutting mechanism (7), a heating unit (8), and a rolling mechanism (9) is characterized in that it comprises a feeding mechanism (6), behind which there is a cutting mechanism (7) with a knife extended above the thickness of the multilayer pipe wall (R), and scrapers are mounted in the rolling mechanism (9) at each of the rollers.
