  • Publication number: 20140144823
    Abstract: An Archimedes screw plant for separating slurry includes a tubular sifting device; a slurry feeding device; a device for evacuating the liquid fraction; and a device for evacuating the substantially dry separated solid. The device includes an upper compaction chamber of the separated solid where a solid plug of product is formed. In addition, the tubular sifting device has an upper opening being provided with an auxiliary contrast element for forming said solid plug of product.

  • Patent number: 8215477
    Abstract: The archimedes screw (1) for use in conveyors, compactors and the like, comprises a shaft (2) on which a helix (3) is coupled, which screw rotates internally of a containing structure, wherein the archimedes screw (1) comprises a plurality of sections (4a, 4b, 4c, 4d . . . 4n) which can be threaded coaxially and solidly in rotation on a central shaft which defines the shaft (2) of the archimedes screw, each of which plurality of sections exhibits different constructional and functional characteristics from other of the plurality of sections.

  • Patent number: 8087353
    Abstract: The machine (4) having an improved drainage grid (1) for compacting humid waste (2) comprises at least an Archimedes screw (7) which rotates internally of a containing structure (11) in which a support structure (13) is afforded for the grid (1). The drainage grid (1) comprises a perforated structure (16) shaped and connected to the fixed structure (13) in such a way as to maintain the perforated structure (16) continuously in contact with the helix (10) of the Archimedes screw (7).

  • Publication number: 20080309948
    Abstract: The process comprises a stage of highlighting a plurality of light points of a free surface of the material contained in the silo, of detecting a position of each of the light points and obtaining electrical signals which are proportional to the detected position of each point, and processing the signals to obtain a virtual reproduction of the free surface of the material which when processed provide desired data. The device for realising the process comprises lasers, which project a laser beam towards the free surface of the material contained in the silo, an optical sensor which detects the position of the light points defined by each laser beam on the free surface, and a data processing system which processes the data relating to the position of the lasers, the inclination of the laser beams, and the detected positions of the light points in such a way as to construct a virtual free surface of the material.
