    • To effectively seal the atmosphere within a chamber against ambient atmosphere, particularly for drying or curing of printing ink by UV radiation, vacuum drying, or the like, a pair of plates (12, 13; 33, 34) are positioned contiguous with a pass-through slit formed in a side wall (6) of the chamber, the plates being formed with recesses, grooves or depressions (7-11; 29) extending transversely to movement of the paper web. Ambient air is conducted at the lateral sides to the recesses or grooves which, preferably, in cross section are circular and formed as semicircular grooves in the respective plates, and suction is applied essentially centrally, with respect to the width of the web (2, 40) by suction pumps (19, 23) which may apply an increading degree of vacuum to the recesses as the wall (6) of the chamber is approached. The width of the ridges adjacent the grooves or recesses can be determined by replaceable strips (35', 36') or by eccentric rollers (34, 35) so that the width of the pass-through slit between the plates can be matched to the thickness of the paper web (2, 40).
    • 为了有效地将室内的气氛与环境气氛密封,特别是通过UV辐射,真空干燥等来干燥或固化印刷油墨,一对板(12,13; 33,34)与一个通道 通孔形成在腔室的侧壁(6)中,板形成有横向于纸幅移动延伸的凹槽,凹槽或凹陷(7-11; 29)。 环境空气在侧面被传导到凹槽或凹槽,凹槽或沟槽优选地在横截面上是圆形的并且在相应的板中形成为半圆形凹槽,并且相对于腹板(2, 40)通过抽吸泵(19,23)连接,当泵室(6)接近时,抽吸泵(19,23)可以向凹槽施加逐渐的真空度。 与槽或凹槽相邻的脊的宽度可由可替换的条(35',36')或偏心辊(34,35)确定,使得板之间的通过狭缝的宽度可与 纸幅(2,40)的厚度。

    • A skimmer is secured to the top of a cyclone separator. The skimmer includes an outer cylinder forming an extension of the conventional air exhaust duct of the separator and an inner concentric cylinder terminating within the lower end of the outer cylinder. A specially constructed spiral directing wall means is secured within the space and directs the fine dust laden peripherial layer of the exhaust air through the outer peripheral portion of the exhaust duct for selective discharge into and from a discharge opening and duct means. A door is provided for the opening, and has a central pivot means to simultaneously open and close the reverse sides of the door. The cylinders define an annular space aligned with the peripherial layer of the upwardly moving air from the cyclone separator. The peripherial air layers move into and through the annular space into the discharge duct or back into the center of the center cylinder while the central relative clean air passes through the center cylinder for discharge. In a drying installation the dust laden air may be recycled to a furnace for incineration and/or as a heat carrier.
    • 撇油器固定在旋风分离器的顶部。 撇渣器包括形成分离器的常规排气管的延伸部的外圆筒和终止于外筒的下端内的内同心圆筒。 专门构造的螺旋导向壁装置固定在空间内,并引导排气的细粉尘外围层通过排气管的外周部分,以选择性地排放到排出口和管道装置中。 为开口提供门,并且具有中心枢轴装置,以同时打开和关闭门的反面。 气缸限定与旋风分离器向上移动的空气的周边层对准的环形空间。 外周空气层通过环形空间进入排放管道或返回到中心圆筒的中心,同时中央相对干净的空气通过中心圆筒排放。 在干燥装置中,载满尘土的空气可以再循环到用于焚烧的炉子和/或作为热载体。
