Abstract:
Provided is a powder distribution device which can perform a desired distribution of even fine powder while suppressing the formation of aggregated particles.
Compressed gas which is supplied from a compressed gas supply source (10) to a gas supply opening (9) flows into a gas pool section (8), is discharged into a compressed gas introduction chamber (5) from nozzles (7), forms a swirl gas flow within the cylindrical tube-shaped compressed gas introduction chamber (5) which is formed at the outer peripheral section of the lower-half section (2a) of a powder introduction pipe (2), and the swirl gas flow spreads downward to form a swirl gas flow which swirls within a cylindrical column-shaped distribution chamber (3) about the center axis (C). Powder which is introduced from the powder introduction pipe (2) enters the distribution chamber (3) from a powder introduction opening (6) which is formed in the lower end part of the powder introduction pipe (2), is exposed to the swirl gas flow and dispersed, and is then distributed together with the gas flow to powder distribution paths (11) after passing through slits (12).
