筛网用于筛选纤维悬浮液,以便去除其中的杂质,它一般是刚性的,不同于柔性的连续筛网。一般要求有尽可能大的开口筛网面积和相对高的抗液压强度。在此,所要解决的技术问题是在确保需要的筛网稳定性的情况下,改进分选效果和/或通流量。如图1所示,压力筛具有一体式的金属筛网,在此为具有垂直的圆柱轴线的圆柱体筛篮形式,该筛网将压力筛的内部空间划分成进料空间和良浆空间。在进
Screens are used to screen fiber suspensions to remove impurities therein, which are generally rigid, unlike flexible, continuous screens. It is generally required to have as large an open screen area and relatively high hydraulic strength as possible. The technical problem to be solved here is to improve the sorting effect and / or the throughput rate while ensuring the required screen stability. As shown in FIG. 1, the pressure screen has an integral metal screen, here in the form of a cylindrical screen basket with a vertical cylindrical axis which divides the internal space of the pressure screen into a feed space and an accept space.
