METHOD AND APPARATUS FOR DISTURBING NETWORKED PULP |
摘要 |
The present invention provides a method (20) of separating pulp from a feed material within a tank (1), the method comprising the steps of (23) introducing the feed material (22) into the tank (1); (24) allowing the feed material (22) to settle in the tank (1); (25) allowing the pulp (21) to form into aggregates (13); (26) allowing the pulp aggregates (13) to settle towards the bottom of the tank (1) and form a networked layer (2) of pulp; and (27) causing a disturbance substantially uniformly across a disturbance zone (16) in an upper region of the networked layer (2), so as to disrupt the networked pulp in the disturbance zone within a predetermined period of time; thereby releasing entrained liquid from the networked pulp in the disturbance zone (16) and increasing the relative density of the pulp below the disturbance zone. The invention also provides a separation device (40) for separating pulp (21) from a feed material (22). |
