Definitions

  • the present invention relates to a device for dehumidifying organic material, particularly originating from urban solid waste.
  • the urban solid waste is a material whose properties may considerably vary in respect of its nature (organic or inorganic), consistence, size and composition. It is already known to perform differentiated collection of USW, for separately storing the different materials which it consist of (organic substances, glass, paper, metals, etc.) in order to make it easier to recycle them or to dispose of them efficiently.
  • the organic material which has been separated should be subjected to aerobic fermentation in order to turn it into an inert material or compost.
  • the degree of humidity of the organic material which originally is about 80%, should be previously reduced to about 40%.
  • a main object of the present invention is to provide a device for dehumidifying organic waste originating from urban solid waste, in order to prepare it for oxygenation treatments and to reduce its size, for ease of conveyance to subsequent stations of treatment or collection and for a reduction of the costs of such conveyance.
  • Another object of this invention is to provide a device that is easy to integrate in traditional waste collection centres and which does not affect the operative continuity of such centres.
  • a further object of this invention is to provide a dehumidification device provided with a rugged structure, in order to reduce the incidence of maintenance or replacement operations.
  • Another object of the invention is to provide a device that may be manufactured cheaply and by means of known processes and equipment, wich are commonly employed in this field.
  • a dehumidification device 10 is installed beside a pit 12 into which a truck 13 unloads material consisting of the organic fraction of urban solid waste which has been collected by the so-called differentiated collection.
  • a bridge crane 14 overhanging pit 12 is operated by an onboard operator to pick up successive portions of the organic material from the pit and to transfer them to the dehumidification device 10.
  • the dehumidification device 10 shown in more detail in Figs. 2, 3 and 4, comprises a horizontal, flat, elongated bedplate 15 resting on the bank of pit 12 and three drums 16, 17 and 18, each comprising a cylindrical, perforated metal sheet with open ends.
  • the drums are normally supported side-by-side on the bedplate, so that their openings at their lower ends 53 are shut by the surface of the bedplate, which acts as a shutting means, while their upper openings 52 are open to the atmosphere.
  • each drum 16, 17 and 18 is externally provided with an edge 40 extending along its upper lip.
  • Shifting means 19, e.g. a hydraulic cylinder, are supported on a longitudinal end of bedplate 15 and are provided with a pushing member 20 adapted to engage an annular salient portion 61 of the wall of the adjacent cylinder (cylinder 16 in the figure) in order to shift the latter and the adjacent drums along bedplate 15.
  • a longitudinal middle portion of bedplate 15 consists of a substantially plane, rigid section 55.
  • Cross-piece 25 has a vertical hole 26 in which is slidable a piston 27 of a squeezing cylinder 28.
  • a horizontal swivel arm 30 is hinged about a vertical axis 32 and, to this purpose, is provided at one end 31 with a bush 39 which pivotally engages a pivot 41 attached to cross-piece 25.
  • Two lifting cylinders 35, 36 hang at right angles on the free end 59 and on a middle point P of the arm respectively.
  • the rods of lifting cylinders 35, 36 are provided with respective hooks 33, 34 adapted to engage edge 40.
  • a crown gear 42 is coaxially keyed to bush 39, and is engaged by a chain 43, whose opposite ends 44, 45 are fastened to the rods of respective linear actuators 46, 47 fastened to cross-piece 25.
  • bedplate 15 The periphery of bedplate 15 is surrounded with gutters 60 leading to a fluid-collection tank S (only diagrammed in Figs. 5-9).
  • the gutters are covered by respective grids 58 adapted to screen any solid residuals.
  • Grids 58 can be tipped towards a download area 56 on one side of bedplate 15.
  • the organic material inside drum 160 is pressed and, while the solid organic material is retained in the enclosed chamber delimited by the drum, the squeezing plate and the substantially plane, rigid section 55 of the bedplate, the excess fluid is drained through the holes 57 on the wall of the drum and flows into gutters 60.
  • drums 160, 170 and 180 cyclically follow one another in performing a process comprising a loading step, a squeezing step, a picking step and a downloading step, thereby enhancing the continuity of the dehumidification process.
  • the organic material is effectively prepared for the subsequent oxygenation treatments.
  • the pressure exerted by squeezing cylinder 28 the amount of fluid drained drum also be adjusted depending on the requirements.
  • the dehumidified material is reduced in weight and volume, so that it will be easier and cheaper to be conveyed.
  • the dehumidification device of the invention is also easy to integrate in traditional waste collection pits 12, such as that shown in Fig. 1, because of its small overall size.
  • a further advantage of this device is its sturdy structure, which allows the pressure exerted by squeezing cylinder 28 upon the organic material in the drum to be reacted by a section of the bedplate which is suitably reinforced to be rigid and rugged. Moreover, the device according to the invention may be cheaply manufactured, by means of known processes and equipment commonly employed in this field.
  • the device can include a different number of cylindrical drums, in order to optimise its operation according to the requirements.
  • the rotation of horizontal arm 30 can be alternatively achieved by a motor driving a crown gear integral with bush 39 of the arm via gears, or by any other known device that will be obvious for the person skilled in the art.
  • Arm 30 can be also substituted by other means adapted to allow the extraction of the squeezed material through the lower end of the drum, e.g. a sliding shutter on the bedplate.
  • the material is downloaded by gravity, downloading can be forced by inserting an extra ejection piston overhanging the download area, which is operated in case the weight of the material in the cylinder is not sufficient to cause the material to fall into the download area.
