Abstract

Une machine de séparation pour séparer le caoutchouc du câblé lors du recyclage de pneus usés possède quelques traits particuliers. Elle est constituée de plusieurs sections qui comprennent des comprennent des mécanismes de traitement de pneus à trois stades. Les sections sont reliées entre elles, par exemple, par des brides. Le boîtier de la section de premier stade se présente comme une pyramide tronquée rectangulaire. Le premier stade de traitement s'effectue par un mécanisme de pressage de convoyeurs à rouleaux. Les convoyeurs sont disposés à un certain angle les unes par rapport aux autres; deux paires de cylindres sont dotées de supports réglables. Le deuxième stade de traitement s'effectue par un marteau plat. Le troisième stade de traitement, qui est un stade de finition terminal, s'effectue par trois paires de cylindres à surface profilée. Un tambour de transfert est raccordé à la section de réception de la machine, et une trémie est raccordée à la section de traitement de finition terminal, ladite trémie étant destinée à la collecte de miettes et de câblé. Dans la section de réception et la section du premier stade de traitement, on a disposé le long de la paroi inférieure un transporteur par vibrations de type à goulot. Le long de la paroi supérieur du boîtier de la machine on a monté une tuyauterie munie de tubulures, destinée à alimenter le corps avec un agent caloporteur liquide, par exemple, avec de l'azote liquide.
