    • A machine for removing sedimentary material from filter beds of water supply installations. The machine has a chassis running on endless tracks and supporting a displaceable front frame carrying an inclined elevated conveyor arrangement with a plurality of circulated buckets. A rotatable drum with projecting paddles or bars serves to project material in a trough which feeds the buckets of the inclined conveyor arrangement. An inclined plate also carried by the frame serves to skim a layer of material from the bed as the machine advances and the drum picks up the material from the plate. A further conveyor extends transversally of the chassis and receives material from the inclined conveyor for subsequent discharge from the machine.
    • 一种用于从供水设备的过滤床中除去沉积物的机器。 机器具有在环形履带上运行的底盘,并且支撑带有多个循环桶的倾斜升高的输送机布置的可移动的前框架。 具有突出的叶片或杆的可旋转滚筒用于将倾斜输送机装置的铲斗的槽中的材料投射到槽中。 由框架承载的倾斜板用于在机器前进时从床上去除一层材料,并且滚筒从板上拾取材料。 进一步的输送机横向延伸,并从倾斜输送机接收材料,以便随后从机器排出。

    • Industrial waste system having lateral lined trenches in a floor comprising spaced parallel side plates with downwardly and inwardly inclined lower sections joined to form a V bottom having a lengthwise gradient sufficient to promote flow of liquids and matter capable of suspension in the liquid from one end to a discharge point at the other end, side wall shoulders for supporting the side plates within the trench with the upper edges of the plates close to floor level, internal filtergrid support shoulders extending horizontally along the inside walls below floor level having filter grids thereon, power driven sprocket and chain means disposed on opposite sides of the side plates and extending substantially the length of the trench liner, carrying transverse scraper bars at a level to scrape the upper surface of the filter grids, and a similarly constructed trunk trench connecting the discharge ends of the lateral trenches, and means for collecting the liquids separate from the waste collected by the scraper bars.
