Abstract:
A particulate object conveying device for conveying particles of a predetermined size, comprising:a stagnating portion;a disc shaped rotor having an outer circumference with a plurality of grooves formed equidistantly about said outer circumference, said grooves being of a fixed size and shape to hold only a single one of said particles of predetermined size, said rotor rotating within said stagnating portion about a rotary shaft, said stagnating portion being disposed on a side of said rotor and having a gap, said stagnating portion having a cross section defined substantially by two radial lines and an arcuate line to form a partial section of a circle, wherein excess particles taken up in movement of said rotor fall into said stagnating portion;a discharge path for discharging said particles from said rotor;a storage section, disposed above said rotor, for storing particulate objects of polycrystalline silicon;a supplying pipeline having an inner tapered surface, said pipeline connecting said storage section to said stagnating portion; anda valve disposed in said pipeline closer to said storage section than said stagnating portion.
