More Information
Summary:The utility model relates to a silicon powder continuous feeding cold hydrogenation fluidization system which is characterized in that a pore plate is horizontally arranged in a flow channel, a driving part is located in a first cavity, a magnetic coupling A is arranged in a second cavity, a magnetic coupling B is arranged in a third cavity, and the driving part drives a partition plate to slide between the flow channel and the first cavity; a feed opening in the bottom of the sealed silicon powder bin is connected with a runner, the runner is connected with a powder inlet of a pneumatic conveyor, a pneumatic inlet of the pneumatic conveyor is connected with a hydrogen pipeline, and an outlet of the pneumatic conveyor is connected with a silicon powder inlet of the cold hydrogenation fluidized bed. Through the self-designed sealed feeder, on the basis of realizing controllable flow regulation, the sealing problem of devices such as a star-shaped feeder and a powder flow regulating valve in the prior art is so
