    • [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.
    • [问题]提供了具有高分离效率的分离装置。 分离装置1包括粉碎单元30(第一粉碎单元),分离单元40(第一分离单元)和传送路径76(第一空气管)。 切碎单元30将包含塑料(第一材料)和粘附到塑料的吸水聚合物(第二材料)的一次性尿布(加工目标)切碎成碎片。 分离单元40在其中容纳由切碎单元30切碎的一次性尿布碎片的状态下使滚筒42旋转,从而将吸水性聚合物通过孔42a与一次性尿布碎片分离。 传送路径76利用空气压力将由粉碎单元30粉碎的一次性尿布碎片传送至分离单元40。 传送路径76具有在第一方向上延伸的部分76a和在部分76a的下游侧上连接到部分76a并沿基本上正交于第一方向的第二方向延伸的部分76b。
