POWDER IMMERSION TREATMENT DEVICE

PROBLEM TO BE SOLVED: To provide a powder immersion treatment device automatically removing particulates such as powders having an increased particle diameter, foreign matters and the like from a fluidization tank without using an additional actuator.SOLUTION: In a powder immersion treatment device: a fluidization tank 20 is disposed with a filter 50 including a conveying surface 52 inclined upward toward a downstream side in a powder moving direction M; an angle β formed by a vibration direction V applied to the conveying surface 52 by an excitation unit 30 and a horizontal surface H is larger than an angle α formed by the conveying surface 52 and the horizontal surface H; and thus, particulates P without passing the sieve opening of the filter 50 are conveyed upward along the conveying surface 52 with vibration applied to the conveying surface 52 by the excitation unit 30, discharged from an extension part 54 extending to the outside of the fluidization tank 20 at the upper end part of the conveying surface 52 and automatically removed from the fluidization tank 20.SELECTED DRAWING: Figure 1 【課題】追加のアクチュエータを使用することなく、粒径が増大した粉体及び異物等の粒子を流動槽から自動で除去する粉体浸漬処理装置を提供する。【解決手段】流動槽２０に、粉体の移動方向Ｍの下流側に向かうに従って上方に傾斜した搬送面５２を含むフィルタ５０を設ける。加振装置３０によって搬送面５２に加えられる振動の方向Ｖと水平面Ｈとのなす角度βが、搬送面５２と水平面Ｈとのなす角度αよりも大きくなるように構成されている。これにより、フィルタ５０の目開きを通過しない粒子Ｐは、加振装置３０によって搬送面５２に加えられる振動によって、搬送面５２に沿って上方に搬送され、搬送面５２の上端部にあって流動槽２０の外側に延出する延出部５４から排出され、流動槽２０から自動で除去される。【選択図】図１
