Zusammenfassung: | To provide a fine particle production apparatus in which sticking of liquid material to the vicinity of a distal end of a nozzle can be directly removed and possibility of damaging the distal end of the nozzle is reduced, and which therefore allows for stable production of uniform particles.SOLUTION: A fine particle production apparatus comprises: a solution tank 10 storing a solution; a nozzle 20 spraying a solution supplied from the solution tank; a furnace core tube 30 heating the sprayed solution and generating fine particles; a recovery device 40 recovering the generated fine particles; and a sticking removal mechanism 50 removing a solid stuck to the nozzle 20. The sticking removal mechanism 50 comprises: an edge portion 52 contacting with the solid stuck to the nozzle 20 and sliding thereby removing the solid; an operation portion 54 operating motion of the edge portion 52. The edge portion 52 is mutually movable between a standby position not for inhibiting spraying of the solution from the nozzle 20 and a sticking removal position for removing sticking on the nozzle 20, and the edge portion 52 does not contact the distal end 22 of the nozzle 20 at the sticking removal position.SELECTED DRAWING: Figure 4
【課題】ノズルの先端部近傍の固着を直接的に除去できると共にノズルの先端部を傷つける虞が低減し、均質な粒子を安定的に製造できる微粒子製造装置を提供する。【解決手段】溶液を貯留する溶液タンク10と、溶液タンクから供給された溶液を噴霧するノズル20と、噴霧された溶液を加熱し微粒子を生成する炉芯管30と、生成された微粒子を回収する回収装置40と、ノズル20に固着した固体を除去する固着除去機構50と、を備え、固着除去機構50は、ノズル20に固着した固体に接触させ摺動させることで固体を除去するエッジ部52と、エッジ部52の動きを操作する操作部54と、を備え、エッジ部52は、ノズル20からの溶液の噴霧を妨げない待機位置およびノズル20の固着を除去する固着除去位置に相互に移動可能であり、エッジ部52は、固着除去位置においてノズル20の先端部22に接触しない。【選択図】図4 |
