    • An object of the present invention is to provide a filtering and condensing apparatus of the suction type which is capable of improving the filtering efficiency by securing the filtering area, while at the same time keeping an integrity of the filtering cloth.A filtering and condensing apparatus of a suction type comprises a sludge tank for containing sludge to be filtered and condensed, and a plurality of filtering plates aligned with each other so as to be disposed to be adjacent to each other in the sludge tank. Each plane portion of the filtering plates extends in the vertical direction. Each of the filtering plates includes a supporting plate in the form of a net, and a filtering cloth in a bag form so as to be integrally sewed on the supporting plate and to house the supporting plate, whereby a filtering chamber is formed inside the filtering cloth, The apparatus further includes a means for sucking the filtering cloth through the filtering chamber, a means for expanding the filtering cloth through the filtering chamber, and a means for constantly applying a tension force to each of the filtering plates which is disposed to be over the periphery of each of the plurality of the filtering plates. Each of the filtering clothes are divided in the lateral direction of the corresponding filtering plate by a plurality of vertically extending seams to form the filtering chamber at every divided zone, the lateral length of a portion of each of the filtering clothes divided by the adjacent seams is set to be longer than the lateral length of a portion of the supporting plate corresponding to the corresponding zone over the entire vertical direction, whereby each of the zones includes an expanding margin upon the expansion of the corresponding filtering cloth.
    • 本发明的目的是提供一种吸入式过滤冷凝装置,其能够通过确保过滤面积来提高过滤效率,同时保持过滤布的完整性。 抽吸式过滤冷凝装置包括用于容纳待过滤和冷凝的污泥的污泥槽,以及彼此对准的多个过滤板,以在污泥槽中相邻设置。 过滤板的每个平面部分在垂直方向上延伸。 每个过滤板包括网状支撑板和袋形式的滤布,以整体缝合在支撑板上并容纳支撑板,由此在过滤器内部形成过滤室 该装置还包括用于通过过滤室吸滤滤布的装置,用于使滤布膨胀通过过滤室的装置,以及用于不断向每个过滤板施加张力的装置,该装置被设置为 在多个过滤板中的每一个的周边上。 每个过滤衣物通过多个垂直延伸的接缝在相应的过滤板的横向方向上划分,以在每个分隔区域形成过滤室,每个过滤衣物的一部分的横向长度除以相邻的接缝 被设定为比在整个垂直方向上对应的区域的支撑板的一部分的横向长度更长,由此每个区域在相应的过滤布的膨胀时包括膨胀边缘。
