▎ 摘  要

NOVELTY - Continuous feeding device, comprises a forward feeding section (1), a rear feeding section (2) and an outer sleeve of the rear feeding section. Conveying waste plastic (6) are passed through the front feeding sectionand the back feeding section entered into the reactor (4) for chemical recovery, the protective gas is input through the outer sleeve of the feeding section, entered into the back feeding section through the hole on the back feeding section pipewall, the inner wall of the pipeline of the feeding section is formed with an air film, and the contact waste plastic and the forward feeding section inner wall of the pipeline. USE - Continuous feeding device for chemical recovery of waste plastics. ADVANTAGE - The device avoids blockage caused by softening, melting and adhesion on the inner wall of the feeding section of the pipe during the chemical recovery of waste plastics, enables continuous operation, continuous feeding greatly improves the feeding rate, and does not need oxygen in the feed section, which is safe and reliable. The device is simple, and has convenient and quick processing and maintenance. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a continuous feeding device. Forward feed section (1) Rear feed section (2) Reactor (4) Waste plastic (6) Shielding gas (7)
