摘要： A cellular drum filter for dewatering suspensions is disclosed, comprising trough means and a filter drum mounted to rotate partially submerged in a liquid suspension in the trough means. Vacuum suction is applied to the surface of the drum from the interior thereof via radial passages communicating preferably with respective axial channels leading to a control head. Each radial passage and each channel has a cross-section whose shape is an arcuate sector of an annulus.

摘要： The disclosure concerns apparatus for disintegrating waste paper and for sorting out fibers to be recovered from the suspension. There is a disintegrating chamber connected by a gravity feed discharge line to a drum type or vibration sorting device. A circulating member disposed in the disintegrating chamber rotates about an axis that is tilted at a small acute angle from the vertical. A screen located beneath the circulating member separates the disintegrating chamber from a discharge chamber beneath the screen. The screen sorts out coarser particles letting only finer suspension paticles pass into the discharge chamber. A first suspension discharge line communicates with the discharge chamber while a second suspension discharge line communicates with the disintegrating chamber immediately above the screen. Both discharge lines empty into each other and lead to the sorting device. Appropriate slides control flow through the two discharge lines. The preferred sorting device is a horizontally oriented, rotatable, perforated drum and the suspension delivered into the drum is screened, with the good suspension being collected and the coarse material being trapped inside the drum to exit from an end.

摘要翻译： 本公开涉及用于分解废纸并从悬浮液中分离待回收的纤维的设备。 存在通过重力进料排出管线连接到鼓式或振动分选装置的分解室。 设置在崩解室内的循环构件围绕垂直方向以小锐角倾斜的轴线旋转。 位于循环构件下面的屏幕将分解室与屏幕下方的排放室分离。 屏幕排出较粗颗粒，只有更细的悬浮颗粒进入放电室。 第一悬浮排出管线与排出室连通，而第二悬浮排出管线与屏幕正上方的分解室连通。 两个排放管线彼此相互排空并导致分拣装置。 适当的幻灯片控制流经两条排放管线。 优选的分选装置是水平定向的，可旋转的多孔滚筒，并且输送到滚筒中的悬架被筛选，其中收集好的悬挂物，并且粗料被捕获在滚筒内以从一端离开。
