摘要： An apparatus for dewatering a pulp is described, comprising a vessel having a pulp chamber for pulp to be dewatered; a pulp inlet to the vessle; pulp outlet from the vessel; a filtrate chamber with an outlet for filtrate expelled from the pulp; a stationary cylindrical screen mounted within the vessel and defining said plup chamber and filtrate chamber on opposite sides thereof; and mechanical cleaning means supported by a shaft and disposed in the pulp chamber close to the screen face of the screen for removing a mat of pulp therefrom. The apparatus further comprises a backflushing means mounted outside the vessel and including a cylinder with first and second end portions and a piston mounted within the cylinder for reciprocal movement therein. The first end portion communicates with the interior of the apparatus, and the second end portion communicates with the filtrate chamber. Furthermore, the backflushing means comprises a power transmitting means for actuating the piston in the cylinder to move reciprocally in cycles each cycle comprising a slow stroke for drawing filtrate slowly into the cylinder and removing pulp slowly therefrom, and a fast stroke for expelling said drawn-in filtrate quickly out from the cylinder and drawing pulp quickly into the cylinder, said quickly expelled filtrate causing a backlfush through the screen.

摘要： A pressure diffuser includes in a liquid-tight pressurized vessel a vertical screen and which screen and vessel wall define first and second interior volumes for transmitting pulp from a pulp inlet to a pulp outlet and receiving displacement (e.g. wash or bleach) liquid transmitted from headers through the pulp. The screen ends have different cross-sectional areas, and quick movement of the screen effects backflushing. The volumes are segregated by a vertical, generally cylindrical, screen. A chamber is provided in communication on opposite sides of a piston therein with the pulp adjacent the pulp inlet and the extracted liquid. By displacing the piston immediately prior to rapidly moving the screen vertically to effect backflushing through the screen, the pulp pressure on the screen is being reduced and at the same time a volume is made available adjacent the pulp inlet in the chamber thus avoiding pressure shocks and compaction of the pulp adjacent the inlet caused by the movement of the screen.

摘要： A method and apparatus for the thickening of a suspension of comminuted fiber material and liquid. A reciprocal screen assembly having a variable volume interior chamber is mounted for movement along the axis of a container through which suspension to be dewatered flows. Mechanical apparatus, such as a hydraulic cylinder actuated rod, moves the screen assembly in either the direction of flow of suspension in the container, or in the direction opposite thereto, and the screen assembly is relatively rotatable with respect to the container. During movement of the screen assembly in the direction of flow of the suspension (at about the same velocity as the suspension flow), liquid passes through the screen assembly into the interior chamber, and is expelled from the container. The screen assembly is moved more quickly in the direction opposite to the direction of suspension flow, and the variable volume of the interior chamber thereof decreases quickly so that backflushing of the screen assembly is effected. Even during backflushing, however, liquid is continuously moved from the interior screen chamber to be expelled from the container. Fins mounted on the screen assembly effect relative rotational movement of the screen assembly with respect to the container (to facilitate cleaning of the screen assembly) during movement in the direction opposite to the direction of suspension flow.
摘要翻译： 一种用于增稠粉碎的纤维材料和液体的悬浮液的方法和装置。 安装具有可变体积内部室的互屏组件，用于沿着要脱水的悬浮液流过的容器的轴线移动。 诸如液压缸致动杆的机械装置使筛网组件沿容器中的悬浮液流动方向或与其相反的方向移动，并且筛网组件相对于容器可相对旋转。 在屏幕组件沿着悬架的流动方向移动（以与悬浮液流速大致相同的速度）运动时，液体通过屏幕组件进入内部室，并从容器中排出。 屏幕组件在与悬浮流动方向相反的方向上更快地移动，并且其内部室的可变容积快速下降，从而实现了屏幕组件的反冲洗。 然而，即使在反冲洗期间，液体从内部筛网室连续移动以从容器中排出。 安装在屏幕组件上的金属丝在与悬挂流动方向相反的方向运动期间影响屏幕组件相对于容器的相对旋转运动（以便于屏幕组件的清洁）。

摘要： A method for the treatment of a suspension, such as pulp, with one or more treatment liquids in a manner that maximizes treatment efficiency and minimizes heat loss. The pulp flows in a flow path confined to a given web thickness, and has first and second opposite sides. Treatment liquid is added to the first side of the flow path at spaced predetermined points along its length. Liquid displaced by the treatment liquid is withdrawn from the second side of the flow path at substantially the predetermined points. The displaced liquid at the first predetermined point along the flow path consists essentially of original suspension liquid, while the liquid fraction of the pulp past the last predetermined point of the flow path is composed mainly of treatment liquid added at the last predetermined point. Treatment can be accomplished at super-atmospheric pressure and at a temperature above 100.degree. C. The web thickness is between about 50-500 mm., and the pulp concentration is between about 7-15 percent and is maintained substantially constant throughout treatment.

The panel has a first part (1) intended for fixed mounting of the panel and a second part (2) with operating keys (19) for activating electrical switches. The two parts are hinged together, and the hinge is formed with a rotary shaft (10) on the no part and a bearing with a cylindrical face (13) on the other part and formed with interengaging projections (16) and depressions (15) such that the second part may assume various angular positions relative to the first part, the force between projections and depressions bearing greater than the necessary operative pressure on the operating keys, but smaller than the force necessary to manually move the second part between the various angular positions. The panel is of simple structure and easy to mount and use. The users may easily set the keyboard part in the desired angular position. Furthermore, the panel yields so that it is not damaged in case of collision with an object.
