Definitions

  • This invention is concerned with an extruding press for treating solid city waste.
  • solid city waste is a material whose specifications are widely variable, both in its nature (organic or inert) and in its consistence, size and composition, and in any case it has a high degree of humidity.
  • This material is usually disposed of in a dump or incinerator, after being sorted mainly in order to remove metals and large-size pieces, and after reducing humidity to below 20%.
  • a press that is suitable for advantageously performing such preliminary treatment is disclosed in IT-A-1 256 197, entitled "Macchina per il trattamento di arrangement aconcentrto umido, particolarmente per il riciclaggio di rifiuti solidi urbani" and in document EP-A-0 684 117.
  • the above press which in the following disclosure is referred to as the known press, substantially comprises a plurality of perforated cylinders carried in a rotating drum that is indexed to align each cylinder firstly with a waste material feeder, secondly with an extrusion station where the waste material is squeezed, and finally with a delivery station where the dry residue is discharged.
  • the drum turns between two stationary walls, the gap between the drum and each wall being minimal, barely sufficient to avoid a sliding contact between them.
  • One of the walls has three apertures located at the feeding station, extrusion station and delivery station, respectively, the perforated cylinders aligning in turn with each of them.
  • the opposite wall is solid in front of the feeder, so that it will plug the cylinder base which is aligned with the feeder and therefore contain the material being loaded. Accordingly, said wall only has two apertures, located at the extrusion station and at the delivery station, respectively, and sealing means are provided for plugging the aperture at the extrusion station.
  • the above known press performs satisfactorily as far as efficiency and yield of the material treatment are conerned, but still has some structural and operational drawbacks. More particularly, the solid wall which permanently plugs the cylinder placed in front of the feeder can be a serious hindrance to restoring the operation of the press in case that unbreakable lumps or pieces of hard, particularly metallic material accidentally jam the press by catching in the gap between the cylinder and the wall. It should be noted that in these circumstances, in order to remove the jamming material, the inside of the cylinder can only be reached from the feeder side after awkward disassembly and removal of the feeder itself.
  • the main object of the invention is therefore to avoid the above serious drawback, by improving the known machine so as to allow the material to be removed quickly and easily.
  • a further object of the invention is therefore to improve the known press so that the perforated cylinders can be easily withdrawn from the drum and replaced, without having to remove the drum from the machine.
  • Fig. 1 shows an extrusion press for city waste according to IT-A-1256197, comprising a frame 10, preferably built as a sturdy portal structure and supporting a drum 12 for rotation around an horizontal axis (not shown).
  • drum 12 comprises a pair of spaced, parallel disks 14 and 16, which are connected by cross members not shown.
  • the drum rotates between two walls 18 and 20, which are integral with frame 10, and is spaced from each wall by a gap L of minimal width, such that it will allow the drum to turn freely between the walls.
  • Drum 12 has three seats such as 22, in which respective perforated cylinders or matrices such as 24 are floatingly received.
  • the three seats 22 are arranged at equal angles around the drum axis, and drum 12 in its rotation will bring each of the three seats, together with its associated matrix, into successive alignment with: an aperture 26 on stationary wall 18, corresponding to a waste feeder 28; a similar aperture on stationary wall 18, corresponding to a waste extrusion station 30: and a further aperture on stationary wall 18, corresponding to an unloading or delivery station of the material resulting from the extrusion.
  • stationary wall 20 is provided, in front of the loading station, with an aperture 34, of a larger diameter than the outside diameter of matrix 24, and aligned with the corresponding aperture 26 in the stationary wall 18.
  • Aperture 34 is plugged by a plugging device comprising a flanged plate 36 having a projection 38 matching aperture 34 of wall 20, and abbutting against the base of the matrix which is dwelling there.
  • Plate 36 is carried on a rod 40 of a double-acting hydraulic cylinder 42, which normally maintains rod 40 extended. Therefore, whenever feeder 32 pushes waste into matrix 24 through aperture 26, the waste material abut against plate 36 plugging aperture 34.
  • drum 12 is stepped to the following extrusion position (station 32), and matrix 24 sliding along aperture 26 of wall 18 acts as a shears to trim any elongated bodies which might happen to be in an intermediate position.
  • the edge of aperture 26 is reinforced with a hard metal 46.
  • drum 12 may occasionally be blocked by a solid, bulky object such as a metal beam 44, which has a greater resistance to shear than the shear action offered by the machine.
  • cylinder 42 is actuated to move plate 36 apart from aperture 34 to the position shown in dotted lines, and the material (including clogging material 44) is pushed out through aperture 34. Plate 36 is then immediately pushed back in order to continue the normal operation.
  • Fig. 3 illustrates how the invention is used for the extraction of the matrix.
  • Fig. 3 is similar to Fig. 2, except that the flange of plate 36 has a set of bores 48 which can be aligned with corresponding threaded bores 50 in matrix 24.
  • Bores 48 do not affect the normal operation of the press as disclosed with reference to Fig. 1, since they are outside the area of the plate involved in plugging the end of matrix 24. However, when it is necessary, plate 36 can be fastened to matrix 24 by means of bolts 52 passing through bores 48 and screwed into bores 50. Hydraulic cylinder 42 can then be actuated to withdraw rod 40 to extract the entire matrix 24 from its seat, without having to disassemble drum 12 from the press.
