|20140144823||ARCHIMEDES SCREW SEPARATION PLANT FOR TREATING SLURRY - 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.||05-29-2014|
|20120247927||ARCHIMEDEAN SCREW - An Archimedean screw comprising a spiral helix. The Archimedean screw is characterized in that it further comprises a central element plastically twisted like a helix about a central symmetry axis. The spiral helix, in turn, is wound about the central element. Furthermore, the central element is the only supporting element of itself and of said spiral helix.||10-04-2012|
|20120099934||APPARATUS AND RELATED METHOD FOR THE RECOVERY AND THE PNEUMATIC TRANSPORATION OF DUST COMING FROM A FILTRATION SYSTEM - An apparatus and related method for the recovery and the pneumatic transportation of dust coming from a filtration system provided with a particulate collection hopper. The apparatus comprises:||04-26-2012|
|20110247920||CONVEYING SCREW APPARATUS FOR TRANSPORTING LOOSE MATERIAL - A conveying screw apparatus for transporting loose material. The apparatus includes: —a power unit apt to rotate an Archimedes screw pushing the loose material; —a charging hopper of the loose material in a tubular body containing the Archimedes screw and the loose material; —a feeding channel of the loose material towards a user; —pushing elements of the loose material present in the feeding channel; and —a back flow preventing device, preventing the back flow of pushing air together with loose material; such a device closing, in case, a through hole to the feeding channel. The back flow preventing device includes a shutter, provided with a plate, undergoing the action of a helical spring which, in any opening/closing step of the through hole, is always substantially perpendicular to the feeding first direction of the material in the tubular body.||10-13-2011|
