纸浆经粗筛等处理去除较大杂质后被引入涡流除渣器中,在纸浆内产生涡流,通过离心力和重力的作用,纸浆中较重的杂质沉到涡流除渣器的底部,从底部去除。图1示出涡流除渣器的操作原理,其中待处理的纸浆从侧面由入口供应。涡流除渣器的少部分壁构成分离锥,该分离锥的直径减小方式使靠近杂质出口的直径比纸浆入口一侧的锥端部处的直径要小。因此,纸浆中较重的杂质被带到涡流的外周并下沉,直到由
The pulp is coarsely sieved and other treatment to remove large impurities after being introduced into the vortex cleaner, the vortex generated in the pulp, by centrifugal force and gravity, the heavier impurities in the pulp sink to the bottom of the vortex cleaner, removed from the bottom . FIG. 1 shows the principle of operation of the vortex cleaner, in which the pulp to be treated is supplied laterally from the inlet. A small part of the wall of the vortex cleaner forms a separation cone whose diameter is reduced in such a manner that the diameter near the impurity outlet is smaller than the diameter at the taper end on the pulp inlet side. As a result, the heavier impurities in the pulp are brought to the periphery of the vortex and sink until it is exhausted
