摘要： In a hydrocyclone, particularly for deinking of paper pulp, a movable generally cylindrical plug is utilized to define an annular space near the accepts withdrawal conduit to effect release of obstructions should the annular space become clogged. The plug is biased by a spring, and moved against the spring pressure to enlarge the annular space automatically in response to a build up of back pressure. The plug also may be moved manually from exteriorly of the hydrocyclone housing, or may be operated by fluidic elements on a periodic basis to clean the annular space whether or not there has been a build up of back pressure. The hydrocyclone preferably is a gas sparged hydrocyclone, and recycled paper--with print on it--having a consistency of at least about 2% is treated to effect deinking.

摘要翻译： 在水力旋流器中，特别是用于纸浆的脱墨，如果环形空间变得堵塞，则使用可移动的大体上圆柱形的塞子来限定接近的抽出管道附近的环形空间。 插头被弹簧偏置，并抵抗弹簧压力移动，以响应于背压的积聚而自动扩大环形空间。 塞子还可以从水力旋流器壳体的外部手动地移动，或者可以周期性地由流体元件操作，以清洁环形空间，而不管是否存在背压的积聚。 水力旋流器优选是气体喷射式水力旋流器，并且处理具有至少约2％的稠度的再循环纸 - 其上具有印刷物以进行脱墨。
