Abstract

Esillä on uudenkaltainen suodosnäytteenotin (100a, 100b) suodosnäytteen keräämiseksi selluliuoksesta. Suodosnäytteenotin (100a, 100b) käsittää: vaipan (140a, 140b), männänvarren (110a, 110b), joka käsittää ensimmäisen pään (111a, 111b) ja toisen pään (112a, 112b), joka männänvarsi (110a, 110b) on järjestetty mainitun vaipan (140a, 140b) sisälle vaipan (140a, 140b) pituussuunnassa, ja rakosihdin (120a, 120b), joka on järjestetty männänvarteen (110a, 110b). Rakosihti (120a, 120b) käsittää lukuisia rakoja (123), jotka ulottuvat männänvarren (110a, 110b) pituussuunnan suuntaisesti.A novel filtrate sampler (100a, 100b) is presented for collecting a filtrate sample from the pulp solution. The filtrate sampler (100a, 100b) comprises: a jacket (140a, 140b), a piston rod (110a, 110b), which comprises a first end (111a, 111b) and a second end (112a, 112b), which piston rod (110a, 110b) is arranged as inside the jacket (140a, 140b) in the longitudinal direction of the jacket (140a, 140b), and a slot screen (120a, 120b) arranged on the piston rod (110a, 110b). The slit filter (120a, 120b) comprises numerous slits (123) that extend parallel to the longitudinal direction of the piston rod (110a, 110b).
