Ejector for granular material color sorting machine

摘要

An ejector for a granular matter color sorter reducing burdens such as cleaning and maintenance in particular associated with a nozzle unit is to be provided. The ejector 10 comprises a nozzle unit 15, a solenoid valve unit 13, and a manifold unit 14. The nozzle unit 15 is constituted by a plurality of nozzle devices 16 that are independent from each other. The solenoid valve unit 13 is constituted by a plurality of solenoid valve devices 19. The respective nozzle devices 16 and the respective solenoid valve devices 19 correspond to each other on a one-on-one basis so that air flow passages of them are connected by an air flow passage of a manifold. The nozzle device 16 and the manifold 29 are detachably connected and made integral in a state where a surface of the nozzle device 16 in which the air flow passage opens and a surface of the manifold 29 in which the air flow passage opens are brought into abutment with each other.
