表示细粒范围内水力旋流器分离函数的曲线是鱼钩形的,即随着颗粒粒度降低分离增加。对于和纵轴相交的分离曲线,提出了用于物理基础模型的方法,相交点相应于水力旋流器底流中回收的体积。鱼钩形曲线可在相应的干扰沉降基础上进行计算。从悬浮液中挤压出沉淀物时,粗粒表面的细颗粒产生了选择性分离。这和层过滤的原理一致。 The curve representing the hydrocyclone separation function within the fines range is hook-shaped, ie increases as the particle size decreases. For separation curves intersecting the longitudinal axis, a method for the physical base model is proposed, with the point of intersection corresponding to the volume recovered in the underflow of the hydrocyclone. The hook curve can be calculated on the basis of the corresponding disturbance settlement. When the precipitate is extruded from the suspension, the fine particles on the surface of the coarse particles are selectively separated. This is consistent with the principle of layer filtering.
