【発明の属する技術分野】
この発明は、集塵装置等のロータリーバルブに関し、特に、排出装置の大口径のロータリーバルブに関する。
【0002】
従来、ロータリバルブは、粉粒体の排出装置として使用されている。そして、可撓性のロータ羽根を用いて噛み込みにくい構造としたロータリバルブは考案されている。(例えば、特許文献1参照)。
【0003】
【特許文献1】
特開昭58−144026号公報(第1−3頁、第1−3図)
【0004】
しかし、その処理物は、粉粒体であり、嵩の大きな処理物は噛み込みの危険性が非常に高く、そのため、嵩の大きな処理物に対応したロータリバルブは、今日まで実用化されてないのが実情である。
【0005】
さらに、従来のロータリバルブでは、本体内に組み込まれたロータを回転させるため、ロータとケーシングとの間に、ある程度のクリアランスを要する。
そのため、機械加工にて、ロータとケーシングとのクリアランスをコントロールし、シール性を維持している。
【0006】
そして、保守点検に関しては、排出不良を引き起こすロータ羽根の磨耗・損傷具合を正確に把握できないので、システム内の他の機器へのトラブルを引き起こす危険性があり、ロータ羽根の交換は大変手間のかかる作業であった。
【0007】
【発明が解決しようとする課題】
そこで、この発明は、嵩の大きな処理物(処理物が、粗大ゴミ・廃プラスチック等の処理場およびリサイクル工場にてサイクロン、バグフィルター等の集塵機により集塵、回収されるシート状・袋状・軽い塊状等の嵩の大きいもの)に対応できる大容量の集塵装置等の排出装置であって、処理物の噛み込みによる運転の停止がなく、装置の製造・加工費を安価にでき、保守点検ができ、トラブルを未然に防ぐことのできる集塵装置のロータリーバルブを開発・提供する。
【0008】
【課題を解決するための手段】
この発明は、ケーシング本体の上部・下部の気密を保持すると共に、ケーシング本体内に、ロータを組込み、減速モータの駆動により回転させ、ロータ羽根を可撓性・耐磨耗性素材で構成し、ケーシング本体にロータ羽根交換用の点検口及びロータ羽根交換用の監視窓を設けたことを特徴とする集塵装置のロータリーバルブである。
【0009】
【発明の実施の形態】
この発明の一実施例を図1〜図4に従って説明すると、集塵装置等の排出装置であって、溶接構造のケーシング本体(1)の上部・下部の気密を保持すると共に、該ケーシング本体(1)内に、減速モータ(2)の駆動により回転するロータ(3)を設け、該ロータ(3)に、複数枚のロータ羽根(4)を設け、かつ、これらロータ羽根(4)は、回転半径より充分長いロータ羽根であって、しかも、可撓性・耐磨耗性素材で構成し、さらに、前記ケーシング本体(1)には、ロータ羽根交換用の点検口(5)及びロータ羽根交換用の監視窓(6)を設けたことを特徴とする集塵装置のロータリーバルブから構成されるものである。
【0010】
尚、上記実施例のケーシング本体(1)は、最小の大きさは、供給口寸法を300ミリメートルとすると、ケーシング本体の高さは、450ミリメートル程度であり、最大の大きさは、供給口寸法を1000ミリメートルとすると、ケーシング本体の高さは、1400ミリメートル程度であり、溶接構造としており、従来の機械加工が不要な構造にすることによって、制作費の大幅な削減ができるものである。
【0011】
また、ケーシング本体(1)より突出したロータ(3)の軸(3a)には、スプロケット(3b)を介して、減速モータ(2)の軸(2a)のスプロケット(2b)と、チエーン(X)で回巻されている。
【0012】
そして、この発明に使用するロータ羽根(4)の一例を図面に従って説明すると、ロータ(3)の周囲より放射状に突出したロータ羽根取付板(4a)を介して取り付けられており、その素材にウレタンゴムを使用しており、その弾力を利用して、ケーシング本体(1)の内壁に摺動して回転するものであり、充分にシール性を保持できるものである。
尚、(4b)は、ロータ羽根押え板であり、前記ロータ羽根取付板(4a)とで、ロータ羽根押え板を構成するものである。
【0013】
さらに、ロータ羽根(4)交換用の点検口(5)は、ロータ(3)と平行なケーシング本体(1)の側面に設けられており、磨耗したロータ羽根(4)を新しいものと取り替えるためのものである。
【0014】
また、ロータ羽根交換用の監視窓(6)は、ケーシング本体(1)の表裏のそれぞれ上・下部に、それぞれ設けられており、内部のロータ羽根の先端部が監視できるよう透明板で覆われており、該透明板には、ロータ羽根(4)が磨耗し、取り替える時期の目安となる目安ライン(6a)が引かれている。
【0015】
【発明の効果】
この発明によると、集塵装置等の排出装置であって、特に、嵩の大きな処理物に対応する大容量であり、ケーシング本体の上部・下部の気密を保持すると共に、ケーシング本体内に、減速モータの駆動により回転するロータを介して複数枚のロータ羽根を設け、かつ、回転半径より充分長いロータ羽根を可撓性・耐磨耗性素材で構成し、ケーシング本体にロータ羽根交換用の点検口及びロータ羽根交換用の監視窓を設けたことにより、以下の効果を奏するものである。
【0016】
先ず、各ロータ羽根(4)を充分な可撓性・耐磨耗性素材で構成したので、処理物がロータ(3)とケーシング本体(1)との間に噛み込もうとしても、ロータ羽根(4)が撓んで逃げる結果、回転を妨げないという効果を奏する。
【0017】
さらに、この発明のケーシング本体(1)は、溶接構造のままであるため、機械加工で行うよりも大幅な経費削減が可能となる。また、回転半径より充分長いロータ羽根(4)でケーシング本体の内壁を摺動することにより、シール性を確保でき、ロータ(3)とケーシング本体(1)とのクリアランスのコントロールが不要であり、その作業を省略できるとの効果を奏する。
【0018】
そして、ロータ羽根交換用の点検口(5)を設けたことにより、従来の交換作業に比べ作業効率が向上し、交換時期の短縮・作業費用の削減が可能となる。
【0019】
また、ロータ羽根交換用の監視窓(6)を設けたことにより、ロータ羽根(4)の磨耗・損傷具合及び交換時期を常時把握でき、システム内の他の機器へのトラブルを未然に防ぐことができる等極めて有益なる効果を奏するものである。
