    摘要： This specification discloses vacuum cleaning apparatus for a rotary drum filter in which a drive screw for moving the suction nozzle axially of the rotary drum is supported by two movable bearings in addition to end bearings. The movable bearings are positioned on guide members which extend parallel to the drive screw to support the drive screw against sagging at locations between the suction nozzle and the end bearings. The movable bearing are spaced by rigid connecting rods. As one movable bearing is pushed along the guide member by the advancing suction nozzle, the rods pull the other movable bearing along to support the drive screw.

    摘要翻译： 本说明书公开了一种用于旋转鼓式过滤器的真空清洁装置，其中用于使旋转鼓轴向移动吸嘴的驱动螺杆除了端部轴承之外由两个可移动轴承支撑。 可移动轴承定位在平行于驱动螺杆延伸的引导构件上，以支撑驱动螺钉，以防止在吸嘴和端部轴承之间的位置处的下垂。 可动轴承由刚性连接杆隔开。 当一个可移动轴承通过前进的吸嘴沿导向件推动时，杆拉动另一个可移动轴承以支撑驱动螺杆。
