Abstract

A device for producing black phosphorus which includes a reactor having one end connected to a feeding pipe and another end connected to a discharge pipe; a propeller blade unit including a rotating shaft mounted between the two ends of the reactor and a blade element mounted on the rotating shaft; a motor connected to the rotating shaft for controlling a rotation speed of the blade element; a heating device enclosing the reactor at an outer side and defines the reactor into a plurality of heating zones; and an inert gas input connected to the discharge pipe. The device is simple and safe in operation, can optimize the production process at low cost, and has high level of automation, thus facilitating a continuous production of black phosphorus under normal pressure.
