    • A port device (10) for processing control, e.g. venting, feeding, co-feeding, additional mixing, etc., when operating a processor for a viscous material, such as a heated polymer composition, typically an extruder; the port device comprises: (i) an enclosure (11) encompassing an elongated and preferably cylindrical cavity (13) extending along a longitudinal and vertical axis (A); the cavity (13) has an axially open first end (101), a second end (109) opposite the first end, and an outlet (102) near the second end; (ii) an elongated rotor arranged within the cavity (13) for rotation in an essentially coaxial alignment with the longitudinal axis of said cavity; (iii) drive means (14, 16) connected with the rotor for rotation thereof within the cavity; and (iv) conveying (121, 122) means for causing a stream of polymer to flow in a direction from the open and toward the closed end and through the outlet when the rotor is actuated by the drive means; the conveying means include at least one scraping flight section (122) provided on the rotor near said outlet, and at least one shearing flight section (121) provided up-stream of said scraping flight section; the viscous material is fed into the cavity through a radial inlet (103).
    • 一种用于处理控制的端口装置(10)。 当用于粘性材料的处理器(例如加热的聚合物组合物,通常为挤出机)时,通风,进料,共进料,附加混合等。 端口装置包括:(i)围绕沿着纵向和纵向轴线(A)延伸的细长且优选圆柱形的空腔(13)的外壳(11); 空腔(13)具有轴向开口的第一端(101),与第一端相对的第二端(109)和靠近第二端的出口(102); (ii)布置在空腔(13)内的细长转子,用于与所述空腔的纵向轴线基本上同轴对准旋转; (iii)与所述转子相连的驱动装置(14,16),用于在所述空腔内旋转; 和(iv)当所述转子由所述驱动装置致动时,使所述聚合物流沿着从所述开放端朝向所述封闭端的方向流动并通过所述出口的装置(121,122); 所述输送装置包括设置在所述出口附近的转子上的至少一个刮除飞行部分(122)和设置在所述刮削飞行部分的上游的至少一个剪切飞行部分(121) 粘性材料通过径向入口(103)进入空腔。
