SCREEN DEVICE AND CONTAMINANT SEPARATION SYSTEM
To cut and shred contaminants when the contaminants clog between coil spring wires.SOLUTION: A screen device 1 comprises: a coil spring 7 in which a wire 27 is spirally wound, to one of an inner side and an outer side of which a processed liquid W1 is introduced and to the other of inner and outer sides of which a penetration liquid PW separated from the processed liquid W1 is discharged; a drive unit 10 for performing telescopic motion of the coil spring 7; and a control unit for controlling the drive unit 10. The wire 27 has a first face which is a spiral cylindrical surface directed to one side, and a second face which is a spiral slant face which is directed to the other side and forms an acute angle between itself and the first face. The control unit has a drive part which so controls the drive unit 10 as to cut contaminants when the contaminants clog between the wires.SELECTED DRAWING: Figure 2
【課題】コイルバネの線材間に夾雑物が目詰まりした場合に、夾雑物を切断して夾雑物を細かくする。【解決手段】線材２７を螺旋状に巻いたコイルバネ７であって、コイルバネ７の内側と外側との一方に被処理液Ｗ１が導入され、他方に被処理液Ｗ１から分離された透過液ＰＷが排出されるコイルバネ７と、コイルバネ７を伸縮する駆動装置１０と、駆動装置１０を制御する制御装置と、を備え、線材２７は、一方を向く螺旋状の円筒面である第一面と、他方を向き、第一面とのなす角が鋭角である螺旋状の斜面である第二面と、を有し、制御装置は、線材間に夾雑物が目詰まりした場合に、駆動装置１０を制御して夾雑物を切断する駆動部を有するスクリーン装置１を提供する。【選択図】図２
