Claims (5)

1. Устройство для промывки целлюлозных волокон, содержащее полый корпус (10), имеющий аксиальные герметизированные камеры (17, 18, 24) для приема потока суспензии целлюлозных волокон и снабженный входным (11) и выходным (12) патрубками, первый и второй неподвижные цилиндрические промывочные фильтры (19, 25), расположенные коаксиально внутри указанного корпуса, которые пропускают жидкость, но задерживают волокна, причем, первый цилиндрический промывочный фильтр (19) расположен внутри второго фильтра (25) с радиальным зазором, cиcтему каналов внутри корпуса (10) для аксиального перемещения суспензии по одной стороне первого фильтра (19), а затем в обратном аксиальном направлении по одной стороне второго фильтра (25); средство (21, 22) для возбуждения пульсации в суспензии на одной стороне фильтров, способствующей просачиванию жидкости сквозь фильтры, средство для сообщения суспензии осевой скорости для перемещения по первому и второму фильтрам (19, 25), средство для сообщения суспензии радиальной скорости для удаления из нее воды при движении по фильтрам и входной патрубок (16), сообщающийся с внутренним пространством корпуса для ввода промывной жидкости, смешивания ее с суспензией и замены отфильтрованной жидкости.1. A device for washing cellulose fibers, containing a hollow body (10) having axial sealed chambers (17, 18, 24) for receiving a stream of suspension of cellulose fibers and equipped with inlet (11) and output (12) nozzles, the first and second fixed cylindrical washing filters (19, 25), located coaxially inside the indicated housing, which allow fluid to pass through but retain fibers, and the first cylindrical washing filter (19) is located inside the second filter (25) with a radial clearance, the channel system inside the housing ca (10) for axial movement of the suspension on one side of the first filter (19), and then in the opposite axial direction on one side of the second filter (25); means (21, 22) for exciting pulsations in the suspension on one side of the filters, which allows fluid to leak through the filters, means for communicating the axial velocity suspension to move along the first and second filters (19, 25), means for communicating the radial velocity suspension for removal from water when moving through the filters and the inlet pipe (16), communicating with the interior of the housing for entering the washing liquid, mixing it with the suspension and replacing the filtered liquid. 2. Устройство по п. 1, отличающееся тем, что средство для возбуждения пульсации включает вращающийся барабан (21), аксиально расположенный внутри полого корпуса с зазором между первым и вторым промывочными фильтрами (19, 25). 2. The device according to claim 1, characterized in that the means for exciting the pulsation includes a rotating drum (21) axially located inside the hollow body with a gap between the first and second washing filters (19, 25). 3. Устройство по п. 2, отличающееся тем, что барабан (21) имеет по существу цилиндрическую поверхность с множеством выступов (28, 29). 3. The device according to claim 2, characterized in that the drum (21) has a substantially cylindrical surface with many protrusions (28, 29). 4. Устройство по п. 3, отличающееся тем, что указанные выступы (28, 29) имеют по существу полусферическую форму. 4. The device according to claim 3, characterized in that said protrusions (28, 29) have a substantially hemispherical shape. 5. Устройство по п. 1, отличающееся тем, что входной патрубок (16) для промывной жидкости расположен так, что эта жидкость поступает в корпус между первым и вторым фильтрами. 5. The device according to claim 1, characterized in that the inlet pipe (16) for the washing liquid is located so that this liquid enters the housing between the first and second filters.
