PROBLEM TO BE SOLVED: To provide a fluidized bed apparatus equipped with a hanging member capable of hanging a bag filter from a bearing member without coming off and damaging the bag filter even in brushing-off operation of a filter part.SOLUTION: A fluidized bed apparatus 1 is equipped with a fluidized bed chamber 2 for granulating floating particulates and a filter part 8 installed in the fluidized bed chamber 2. The filter part 8 is composed of a plurality of filters 10 having a hanging part 18, and a bearing member 11 having a through-hole 11a at a hanging position and capable of hanging each filter 10, and a hanging member 17 made of a spiral wire and capable of hanging the filter 10. A part of the spiral of the hanging member 17 is inserted into the through-hole 11a and another part of the spiral is inserted into the hanging part 18 to hang the filter 10 from the bearing member 11.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】フィルター部の払い落とし操作によっても外れることがなく、また、バグフィルターを破損することがなく、バグフィルターを支持部材に吊下げ可能な吊下げ部材を有する流動層装置を提供する。【解決手段】粉粒体を浮遊流動させながら、造粒等を行う流動層容器2と、流動層容器2の内部に配置されたフィルター部8とを備えた流動層装置1において、フィルター部8は、吊り部18を有する複数のフィルター10と、吊下げ位置に貫通孔11aが形成され、それぞれのフィルター10を吊下げ支持可能な支持部材11と、螺旋状に巻かれた線材で形成され、フィルター10を吊下げ可能な吊下げ部材17とを有し、吊下げ部材17は、螺旋の一部分が貫通孔11aに挿通され、かつ螺旋の一部分が吊り部18に挿通された状態で、フィルター10を支持部材11に吊下げることを特徴とする。【選択図】図1
