Abstract
PURPOSE:To automatically execute all the operations of sampling and measurement of specimen and calculation of measured value, by measuring pulp slurry density by light permeability, calculating weight of required specimen by the vessel and operating titration. CONSTITUTION:By introducing unbleached pulp specimen from an inlet 3, showering on it cleaning water from a cleaning water line 4 and rotating it around a rotary center 5, a K-value measuring pulp slurry is taken out from an outlet 8. And then, after pulp density was measured from light absorption measurement value of the pulp slurry, refined nbleached pulp is put into a container 16, and then, after the slurry was adjusted by being diluted by a given volume of water, it is taken out by a pump 10 and sent over to a flow cell 12 where its light permeability is measured by a light source 13 and a detector 14, and volume of slurry liquid corresponding to a prescribed weight is automatically calculated. And, by adding a reagent by a volume corresponding to the specimen, permanganate number is calculated from titration and measurement vaue. It is possible, by doing so, to control pulp manufacturing process with rapidity and accuracy.
