Assembly for recovering polysilicon fragments and method for recovering polysilicon fragments from a polysilicon cleaning apparatus

摘要

A structural unit for recovering polysilicon fragments comprises a polysilicon cleaning device designed to clean a plurality of polysilicon bodies. Also included is a plurality of polysilicon fragments produced by the polysilicon bodies as they are being cleaned, each of the plurality of polysilicon fragments having a longest dimension in the range of 0.1 mm to 25.0 mm. Further included is a polysilicon emptying conduit configured to convey the plurality of polysilicon fragments from the polysilicon purifier to a debris removal main, the debris removal main being away obliquely oriented downwardly from the polysilicon emptying conduit. Also included is a fluid source in fluid communication with the debris removal main and configured to supply fluid to the debris removal main to drive the plurality of polysilicon debris through the debris removal main.
