Abstract
This invention is about an industrial continuous cracking device of plastics. The technical program of this invention is as following: it includes the outer cylinder and the internal cylinder, and the two sides of the internal cylinder are connected with the outer cylinder; at least one of the outer cylinder and the internal cylinder is set with heating mechanism, and the helical ribbon is fixed in the inside of the outer cylinder wall; the transport mechanism is fixed in the internal cylinder, with its direction contrary to the outer cylinder's the feeding direction. The structures of this invention are simple, and it can reduce the possessive space. Furthermore, when cycling in the cylinder, the solid heat carrier has no heat energy loss, and that can substantially reduce the operation cost of the equipment.
