図1は、切削や研磨等の機械加工を行う工作機械1と濾過装置10とを模式的に示している。工作機械1の一例は、低圧側供給系2と高圧側供給系3とを含んでいる。低圧側供給系2は、比較的低圧(例えば1MPa未満)の液を第1の液使用部1aに供給する。高圧側供給系3は、比較的高圧(例えば1.5~3.0MPa)の液を第2の液使用部1bに供給する。低圧側供給系2は、被加工物Wやその周囲に向けて、液(例えばシャワークーラント)を噴射する。
図1に濾過装置10の概略が示されている。図2は濾過装置10の平面図、図3は図2中のF3-F3線に沿う断面図、図4は図3中のF4-F4線に沿う断面図、図5は濾過装置10の一部を示す斜視図ある。
一次コンベア槽11は、液流入口12とスラッジ掻き上げ部13とを有している。工作機械1から送られてくる濾過すべき液Q1は、液流入口12から一次コンベア槽11内に供給される。スラッジ掻き上げ部13は一次コンベア槽11の端部から斜め上方に延び、最上部にスラッジ排出部14が形成されている。
工作機械1から排出された液Q1は、戻り流路4と液流入口12とを通じて一次コンベア槽11に供給される。一次コンベア槽11の底部11aに沈んだ削り屑などを含むスラッジは、第1のコンベア20のスクレーパ23によって、スラッジ排出部14に搬送される。一次コンベア槽11内の液Q1は、一次ドラムフィルタ30によって一次濾過され、第1の開口41を通って二次コンベア槽40に流入する。一次ドラムフィルタ30に付着したスラッジは、掻き板37によって掻き落とされる。
