摘要： The invention relates to an improved design of the bottom of a continuous digester reducing the torque load on conventional bottom scrapers with scraper arms arranged at an angle α in relation to the horizontal plane in the range between 5°-30°. A simple digester shell extension VE is installed below the lowermost wash screen WS, ending at a small distance D above the end of the outer end of the scraper arm 2b. The shell extension prevents the descending pulp column from expanding below the wash screen and enables easier shaving action from the scraper, using a dilution and expansion volume established at the outer ends of the scraper arms.

摘要： The invention concerns a method and an arrangement for the improvement of a wash after completed digestion in a continuous digester (1) for the production of cellulose pulp. According to the invention, the softened chips are exposed to a radially directed displacement wash after they have passed the rotating bottom scraper (36), and which displacement wash has been established in the flow of digested softened chips through the outlet tap (10) before the softened chips are defibrated by the fall in pressure across the blow-valve that is arranged after the digester.
