摘要： A screen apparatus includes a tank, a first cylidrical screen disposed inside the tank to form a first chamber, and a second cylidrical screen disposed outside the first cylindrical screen. The second cylindrical screen defines a second′ chamber facing the first cylindrical screen and having upper and lower portions communicating with an inlet portion, and second″ chamber. A connection member has a groove facing the second′ chamber at an intermediate portion of the second cylindrical screen, and a passage communicating with the groove for discharging a paper stock. The paper stock flows to the second′ chamber through the upper and lower portions. A part of the paper stock passing through the first and second cylindrical screens is discharged through first and second selection outlet portions, and a part of the paper stock not passing throught the first and second cylindrical screens is discharged through the passage.

摘要： A screen device includes a screen dividing a tank into a first chamber and a second chamber for sorting a foreign material in a papermaking material, a first papermaking material supply passage for supplying the papermaking material to the first chamber from the upper side, and a second papermaking material supply passage for supplying the papermaking material to the first chamber from the lower side. The papermaking material passing through the screen is ejected from a middle area of the screen. The screen device also includes an agitating member located inside the first chamber for agitating the papermaking material, and a foreign material outlet passage communicating with the first chamber through a foreign material outlet provided on a side face of the screen. Therefore, the screen device can improve the sorting effect between the foreign material and a good-quality fiber in the papermaking material.
