Abstract
Description
また、集塵機には様々な形態の機種が存在するが、その一つとして、例えば、特許文献1に記載されたような、封筒型ろ布を用いた集塵機が知られている。
さらに、この封筒型ろ布を用いた集塵機において、例えば、特許文献2には、封筒型ろ布の表面に付着した粉塵を定期的に払い落し、圧力損失を回復させるためのシェーキング式払落し式装置が設けられた集塵機も知られている。
このように構成された本発明においては、集塵機の集塵用ろ布ユニットが、上端が開口した複数の封筒型ろ布が並列配置されたろ布群と、このろ布群の開口側の外周部に貼付けられた枠形状のパッキンと、このパッキンが取り付けられたろ布群を仕切部材に取り付けるためのろ布取付用部材とにより構成されるので、集塵用ろ布ユニットを構成する部品点数を低減することができる。また、ろ布取付用部材に、各封筒型ろ布の開口側の両端部を挟持する挟持部が形成されているので、各封筒型ろ布表面に粉塵が付着して、ろ布重量が増加し、ろ布を下方へ引っ張る力が大きくなっても、封筒型ろ布の開口側の両端部が挟持部に挟持されるため、各封筒型ろ布がろ布取付用部材からずれることなく、また、下方へ引っ張る力を分散することができ、シール性の低下を防止することができる。さらに、ろ布群の開口側の外周部に枠形状のパッキンを貼付けたので、集塵用ろ布ユニットの分解・組立を容易且つ迅速に行なうことができ、作業性が向上する。
このように構成された本発明によれば、封筒型ろ布をスリットにセットする際に、板状突起が封筒型ろ布をスリットに向けてガイドするので、封筒型ろ布のろ布取付用部材への取り付けが容易となる。
このように構成された本発明によれば、ろ布取付用部材の挟持部の板状突起の先端部が鋭角に形成されているので、封筒型ろ布をスリットにセットする際のガイド機能がより向上する。
このように構成された本発明においては、連結棒と複数の払落し部材を備えたしゃーキング式払落機構を有するので、連結棒を操作して、連結棒を水平方向に動かし、これにより、各払落し部材により、封筒型ろ布の表面に付着した粉塵をはたき落とすことができるようになっている。これにより、集塵用ろ布ユニットの圧力損失を低下させることができ、安定した風量で集塵機を運転することができる。
このように構成された本発明においては、各封筒型ろ布の間に介在させた払落し部材の配置を上記のように特定することにより、十分な粉塵払い落し効果と、ろ布間隔の保持効果とを発揮させることができる。
このように構成された本発明においては、払落し部材の形状が、上辺を水平とした逆三角形であるので、十分な粉塵払い落し効果と、ろ布間隔の保持効果とをより効果的に発揮させることができる。
このように構成された本発明においては、連結棒を作業者がシェーキングハンドルにより操作して、連結棒を水平方向に動かし、これにより、各払落し部材により、封筒型ろ布の表面に付着した粉塵をはたき落とすことができる。
このように構成された本発明においては、連結棒を駆動モータにより連結棒を水平方向に動かし、これにより、各払落し部材により、封筒型ろ布の表面に付着した粉塵をはたき落とすことができる。
