摘要： The problems of non-uniform treatment of paper pulp that may be caused by differential flow velocities within a vessel, channeling, and/or disruption of the pulp flow, are substantially eliminated by providing a non-circular cross-section substantially atmospheric pressure vessel with at least one screen surface, and typically a liquid introducing device. The vessel, screen surface, and liquid introducing device are constructed and positioned with respect to each other so that during the treatment of a pulp slurry the slurry has substantially uniform width in a treatment zone, and there is substantially uniform resistance to the flow of slurry over the screen surface over any particular cross-section of the vessel in the treatment zone, and its consistency varies less than 6% in the treatment zone (e.g. between 8-14%). The screen surface may comprise substantially vertical screening portions vertically spaced by non-screening portions, and the vessel wall may bulge out at the location of the non-screening portions so as to provide a slurry width at the bulges at least five percent wider than at the screening portions. The vessel may have a substantially race track shape in cross-section at the treatment zone, and the slurry width may form an annulus in the vessel, the annulus being substantially uninterrupted in the treatment zone (there being no arms or like structures which disrupt the flow). The screen surface may be rotated 5-30°, or oscillated or vibrated horizontally (transverse to pulp movement) to minimize plugging.

摘要： Arrangement for a continuous diffuser for washing pulp, comprising a number of hydraulic cylinders distributed in a ring, arranged so as to repeatedly raise and then lower a screen assembly which is included in the diffuser. The characterizing feature of the invention is that groups of two or more hydraulic cylinders which lie adjacent to each other in the ring are coupled in parallel with each other, but in series with the next group of adjacent hydraulic cylinders which are also coupled in parallel, so that each group of parallel-coupled hydraulic cylinders is coupled in series with the next group of parallel-coupled hydraulic cylinders.

摘要： In an atmospheric diffuser for the treatment of paper pulp (thickening, bleaching, and/or washing) the flow of backflushing liquid is controlled so as to maximize the effective treatment of the pulp. The pulp passes upwardly in a vessel. A number of annular screen assemblies are provided, with at least one screen associated with each screen assembly. The lower screen includes a barrier wall with a passage in the barrier wall adjacent the bottom end of the screen. Liquid which flows through the screen must flow to the passage in order to be withdrawn from the vessel, as the screen is slowly moved upwardly. When the screen is rapidly moved downwardly to cause backflushing, the backflushing liquid at the top end of the screen is liquid that recently passed through the screen at that point, so the pulp at that point --which is the cleanest along the length of the screen--has a minimal chance of being contaminated. The barrier may be provided by a number of tubes separated by webs, or a number of channels separated by webs. A baffle may be mounted between each passage and screen to redirect the backflushing liquid so that it does not merely backflush the bottom portion of the screen.

摘要： The screens of a pulp treating vessel, such as a paper pulp thickener, or diffuser, are back flushed in a simple yet effective manner. The screens are mounted to a supporting conduit within a vertical vessel, and a cylinder is connected at one open end to the conduit, and the other open end is disposed within the pulp inside the vessel. A piston is mounted within the cylinder and relative movement between the piston and cylinder is effected periodically in order to force liquid from within the cylinder into the conduit and out the screens, backflushing the screens and preventing clogging. Since no additional volume of liquid is added to the vessel during backflushing, no surge occurs in the vessel. Conventional accumulators, on/off valves, and the like can be eliminated while--in the case of diffusion washing--efficiency can be increased as much as 20-30% and capacity increased as much as about 15%.
摘要翻译：纸浆处理容器（例如纸浆增稠剂或扩散器）的筛网以简单而有效的方式回流。屏幕安装在垂直容器内的支撑导管上，并且气缸在一个开口端连接到导管，另一个开口端设置在容器内部的纸浆内。活塞安装在气缸内，并且周期性地实现活塞和气缸之间的相对运动，以便将液体从气缸内进入导管并从屏幕出来，反冲洗屏幕并防止堵塞。由于在反吹期间不会向容器中添加额外体积的液体，所以在容器中不产生浪涌。可以消除传统的蓄能器，开/关阀等，而在扩散洗涤效率的情况下可以增加多达20-30％，容量增加多达约15％。
