    • A method and an apparatus for treating pulp are described. The apparatus comprises a vessel (10) in which a wire-surfaced cylinder (12) is mounted and tightly sealed at the ends, a doctor blade (92) located externally of the wire surface and a source of pressure medium for moving and discharging a pulp web from the wire surface. A plurality of adjacent filtrate compartments (20) form a shell on the cylinder (12) and filtrate tubes are located at at least one end of the cylinder (12) and extend inwardly from the compartments (20). A suction means is connected to the inner end of the filtrate tubes and the doctor blade (92) is provided such as to be flexible in the radial direction of the cylinder (12) to provide an improved removal of pulp from the wire surface.

    • The present invention relates to a method and apparatus for treating pulp, which method and apparatus are especially suitable for treating fiber suspensions in wood processing industry. The method and apparatus are particularly designed for thickening said suspensions, in other words filtering liquids from fiber suspensions in pulp and paper industry. The invention relates more closely to a so called drum cylinder, the basic construction of which comprises a vessel, into which suspension being thickened is supplied and a wire-surfaced cylinder rotating in the vessel. The drum filter in accordance with the present invention is characterized in that the closing member (40) of the drum filter has a channel (70) for leading gas from the filtrate tubes (24) through the compartments of the distribution chamber (26) to the outside of the closing member (40). The method in accordance with the present invention is characterized in that the operation phase of the filter cylinder is divided into five stages separated from each other, in the first stage, when the cylinder descends into the vessel, air and the initial filtrate are discharged from the filtrate compartments and the formation of the pulp web on the wire surface begins; in the second stage filtrate is discharged with vacuum and the formation of the pulp web continues; in the third stage pulp web is dried by means of vacuum when said part of the web has risen with the cylinder from the vessel; in the fourth stage, a so called removal stage, pulp web is removed from the wire surface and discharged from the apparatus; and in the fifth stage, a so called washing stage, the wire surface is washed.
    • 本发明涉及一种处理纸浆的方法和装置,该方法和装置特别适用于处理木材加工业中的纤维悬浮液。 该方法和装置特别设计用于增稠所述悬浮液,换句话说,从纸浆和造纸工业中的纤维悬浮液中过滤液体。 本发明更具体地涉及所谓的鼓筒,其基本结构包括容器,其中供应有增稠的悬浮物和在容器中旋转的线表面的圆筒。 根据本发明的滚筒式过滤器的特征在于,滚筒式过滤器的关闭件(40)具有用于将来自滤液管(24)的气体引导通过分配室(26)的隔室的通道(70) 关闭构件(40)的外部。 根据本发明的方法的特征在于,过滤筒的操作阶段被分成五个阶段,在第一阶段中,当气缸下降到容器中时,空气和初始滤液从 滤液隔间和线表面上的纸浆网的形成开始; 在第二阶段,滤液真空排出,纸浆网的形成继续进行; 在第三阶段,当所述纤维网的一部分与所述圆筒从所述容器上升时,通过真空干燥纸浆网; 在第四阶段中,所谓的去除阶段,将纸幅从线表面移出并从设备中排出; 在第五阶段,所谓的洗涤阶段,丝线表面被洗涤。
