PROBLEM TO BE SOLVED: To increase discharge efficiency in discharging the air and bubbles held by increasing discharge velocity and increase cleaning efficiency by increasing the velocity of a detergent at the time of circulation cleaning by disposing an internal drum inside a roller to form a channel for a liquid substance between the internal drum and the internal side of a screen, thereby discharging the liquid substance smoothly.SOLUTION: The internal drum Rd is disposed so as to be along the inner circumferences of rollers R1, R2, and the liquid substance separated with the screen is allowed to flow along a channel Rc formed by a screen Rs and the internal drum Rd and is collected at an outlet 11 for discharging. In addition, the liquid substance inside the rollers R1, R2 are sent to the front and/or the outer circumference of the internal drum Rd aiming at the outlet side, and a paddle (blade) 10 that sends the liquid substance is mounted.COPYRIGHT: (C)2011,JPO&INPIT【課題】 ローラ内に内部ドラムを配設して、その内部ドラムとスクリーン内側との間で液状物の流路を形成させて、液状物の排出をスムーズに行い、排出流速を上げて溜まった空気や泡の排出効率を高めるとともに、循環洗浄時は洗剤の流速を高めて洗浄効率を上げる。【解決手段】 ローラR1,R2内周に沿うように内部ドラムRdが配され、スクリーンで分離した液状物をスクリーンRsと内部ドラムRdとで形成される流路Rcに沿って流して出口11に集めて排出する。また前記内部ドラムRdの前方ないしは外周に出口側に向かってローラR1,R2内の液状物を送り込み、送液するためのパドル(羽根)10を装着する。【選択図】 図1
