SEPARATION DEVICE

摘要

[Problem] A separation device having a high separation efficiency is provided. [Solution] A separation device 1 includes a shredding unit 30 (first shredding unit), a separation unit 40 (first separation unit), and a transfer path 76 (first air pipe). The shredding unit 30 shreds a disposable diaper (processing target) containing a plastic (first material) and a water-absorbent polymer (second materials) adhering to the plastic into fragments. The separation unit 40 rotates a drum 42 in a state in which the disposable diaper fragments shredded by the shredding unit 30 are accommodated therein, thereby separating the water-absorbent polymer passing through holes 42a from the disposable diaper fragments. The transfer path 76 transfers the disposable diaper fragments shredded by the shredding unit 30 to the separation unit 40 with air pressure. The transfer path 76 has a portion 76a that extends in a first direction, and a portion 76b that is connected to the portion 76a on a downstream side of the portion 76a and that extends in a second direction substantially orthogonal to the first direction.
