Abstract: The sidewall of a rotary filter drum is provided with raised, perforate decking across which is formed a plurality of parallel grooves encircling the drum. Loops of filter medium are trained about the drum and rollers spaced therefrom. The loops are in a single layer and seat in the grooves to thereby be maintained in parallel, spaced-apart relationship. Division strips are provided longitudinally across the drum between sections of the decking to seal against the loops of filter medium between said sections. A circumferential seal is provided about the drum ends to stop leakage from the edges of the decking section while allowing expansion of the decking. An adjustable device is provided for tensioning the loops and for discharging cake therefrom.
Abstract translation: 旋转过滤鼓的侧壁设置有凸起的穿孔板，跨越其形成有环绕滚筒的多个平行的槽。 围绕与其间隔开的滚筒和滚子对过滤介质的循环进行培训。 这些环在单层中并且位于凹槽中，从而保持平行且间隔的关系。 分段条纵向设置在滚筒的两个部分之间，以密封在所述部分之间的过滤介质的环之间。 围绕滚筒端部设置周向密封，以阻止甲板边缘的泄漏，同时允许甲板膨胀。 提供可调整的装置用于张紧环路并从中排出饼干。

Abstract: A rotary disc vacuum filter includes a trunnion (2), a plurality of conduits (3) detachably mounted to the trunnion (2) which conduits (3) have an open end (5), an opposite closed end (6), openings (4) therealong and a groove (8) adjacent the open end (5) of the conduits (3) shaped so as to hold an O-ring (9), a collar (11) mounted to rotate with trunnion (2) having apertures (12) for slideably accepting the open end (5) of the conduits (3) so that the O-ring (9) forms a seal and means (15) for detachably mounting the conduits (3) to the trunnion (2) adjacent the closed end (6) of the conduits (3). The filter further including ferrules (37) which are detachably mounted in the openings (4) of the conduits and (3). The plurality of conduits and ferrules mounted in accordance with the above facilitate problems related to replacement and alignment of filter elements.
