摘要： The present invention discloses a method and a centrifugal pump for pumping fiber suspensions of the pulp and paper industry in which the fiber suspension is caused to flow into a centrifugal pump housing in which space a vortex flow is created to prevent the suspension from forming a strong fiber network and from causing blockage of the system.
The centrifugal pump includes a housing provided with one inlet (22) and at least two non-symmetrical outlets (92, 94), at least one of the outlets being preferably provided with a means for regulating the flow through the outlet. The centrifugal pump further includes an impeller/rotor (78, 80) for moving the suspension through the several outlets (92, 94) towards further processing devices.摘要翻译： 本发明公开了一种用于泵送纸浆和造纸工业的纤维悬浮液的方法和离心泵，其中使纤维悬浮液流入离心泵壳体，在该壳体内产生涡流，以防止悬浮液形成强烈的 纤维网络和系统的阻塞。 离心泵包括设置有一个入口（22）和至少两个非对称出口（92,94）的壳体，至少一个出口设置有用于调节通过出口的流动的装置。 离心泵还包括用于将悬架通过多个出口（92,94）移动到另外的处理装置的叶轮/转子（78,80）。

摘要： The present invention relates to a method and an apparatus for optimizing the control and treatment of fibre suspension flow. The invention is mainly intended to be applied in connection with pumping of high consistency pulp in pulp and paper industry. In general, a control valve is provided on the discharge site of the pump in order to regulate the flow. Problems with high pressure loss across the control valve or clogging of the valve are eliminated or minimized by the method and apparatus (19) according to the invention, in which in close proximity to the flow side surface of the valve element (19) a fluidizing element (22) is arranged, which fluidizes the pulp to a liquid state so that the pulp can flow through the valve opening (16) and not clog it.

摘要： The present invention relates to a method and apparatus for keeping a screen surface or a filter surface clear. The method and apparatus according to the invention is especially suitable in connection with thickeners, screens and filters intended for treating the fiber suspensions in the pulp and paper industry.
The greatest disadvantage of all above-mentioned equipment is the tendency of perforated screen/filter surfaces to become gradually clogged as fibers of pulp suspensions adhere to the openings in the screen/filter surface.
In the method of the invention, pressure fluid is introduced from a conduit (5) to the secondary side (10) of the screen/filter drum (6), which fluid flows, during the underpressurized stage caused by the blades (9) of the rotor (7) rotating on the primary side of the screen/filter drum (6), through the screen/filter drum (6) from the secondary side to the primary side thereby rinsing the openings of the drum (6) and making them clear.摘要翻译： 本发明涉及一种保持屏幕表面或过滤表面清洁的方法和装置。 根据本发明的方法和装置特别适用于用于处理纸浆和造纸工业中的纤维悬浮液的增稠剂，筛网和过滤器。 所有上述设备的最大缺点是当纸浆悬浮液的纤维粘附在筛网/过滤器表面上的开口时，穿孔筛网/过滤器表面逐渐堵塞。 在本发明的方法中，压力流体从导管（5）引导到筛网/过滤鼓（6）的次级侧（10），该流体在流体流动的过程中由叶片（9） 在筛网/过滤鼓（6）的初级侧旋转的转子（7）通过筛网/过滤鼓（6）从次级侧到初级侧，从而漂洗滚筒（6）的开口并使它们 明确。
