Abstract

Изобретение относитс  к ситам и может быть использовано в целлюлозно-бумажной промышленности дл  сортировани  волокнистых суспензий. Цепь изобретени  - повьш1ение надежности функционировани  сита и увеличение производительности процесса сортировани  за счет эффективного использовани  ситовой поверхности. Сито дл  сортировани  волокнистой суспензии состоит из основани  1 с р дами 2 выполненных в нем сквозных каналов перфорации 3 дл  отвода кондиционной суспензии. При зтом между смежными каналами перфорации 3 по крайней мере в некоторых из р дов 2 основани  1 сита выполнены сквозные щели 4 дл  отвода длинноволокнистой фракции кондиционной суспензии. Длинные волокна ориентируютс  вдоль щелей и проход т через них, не задержива сь ситом. 1 з.п. ф-лы, 2 ил. с S (ЛThe invention relates to sieves and can be used in the pulp and paper industry for sorting fibrous suspensions. The circuit of the invention is to increase the reliability of the screen and increase the productivity of the screening process due to the effective use of the screen surface. The sieve for sorting the fibrous suspension consists of a base 1 with a series of 2 through-perforation channels 3 made therein for discharging the conditioned suspension. With this, between the adjacent perforation channels 3, at least in some of the rows 2 of the base 1 of the sieve, through slots 4 are made to drain the long-fiber fraction of the conditioned suspension. The long fibers are oriented along the slits and pass through them without being delayed by the sieve. 1 hp f-ly, 2 ill. with S (L
