| 摘要 |
The present invention relates to a method and to a system of apparatus for automated, intermittent extraction of liquid from liquid containing cellulose pulp of high pulp consistency for analysis of the chemical content of said liquid, wherein a collecting unit of given volume is inserted into a transport line or a vessel, wherein the cellulose pulp is advanced in a solid, voluminous state and the collecting unit, together with its content of cellulose pulp, is withdrawn from the transport line or the vessel and moved into a storage space located in connection with the transport line or vessel, and wherein the cellulose pulp is caused to leave the collecting unit and the cellulose pulp is then transported further in an unchanged or lowered pulp consistency, characterized in that the cellulose pulp is delivered to a dilution space to which there is supplied a controlled amount of water together with the cellulose pulp and/or explicity so as to obtain a pulp fibre suspension of comparatively low pulp consistency; and in that the pulp fibre suspension is thereafter de-watered so as to obtain a pulp fibre cake and a flow of liquid that is essentially fibre-free, wherein said liquid flow is removed from the system and passed to an analysis position, whereafter the dilution space is freed from pulp fibres so as to prepare the system for the extraction of fresh liquid for analysis. |
