Definitions

  • the present invention relates to an improvement in a waste-compacting machine, particularly for urban solid waste (USW).
  • USW urban solid waste
  • Machines which compact urban solid waste by pressing it under very high pressure, thereby causing its humid fraction, which can be recycled for production of fertilizers, to be separated from its dry fraction, which can be recycled as fuel.
  • a waste-compacting machine which comprises three perforated cylinders supported on a revolving drum and arranged to be cyclically filled with the material to be compacted.
  • the drum is driven to rotate by steps so that all the cylinders are successively conveyed in front of a plunger, which penetrates into the cylinder and squeezes the material contained therein, thereby causing the fluid fraction to be drained through the holes.
  • a plate integral with the frame rises in front of the loading side base of the drum and is provided with an opening through which the material is loaded into that cylinder aligned to the opening.
  • the rotation of the drum causes the excess fraction of USW to be cut off by shearing between the adjacent surfaces of the cylinder and of the plate.
  • the shearing surfaces are subjected to wear so that the gap between them tends to widen, with a risk that rigid bodies enclosed in the material become stuck between the drum and the screen, thereby blocking the rotation of the drum and causing damages in the structure.
  • a waste-compacting machine 10 comprises a frame 12 provided with two cross-pieces 14, 16 supporting respective transversal plates 18, 20 with a horizontal drum 22 pivotally supported between them about a longitudinal axis A.
  • Drum 22 supports three perforated cylinders 24 which are open at their ends, have horizontal axes, and are spaced at equal angles from each other around the axis of the drum.
  • a cylindrical, compaction chamber is defined within the cylinders.
  • a loading station 26 and an unloading station 28 are arranged in front of one longitudinal end of the drum, while a squeezing station 30 is arranged in front of the opposite end.
  • the three stations are angularly spaced from each other around the axis A, correspondingly to cylinders 24.
  • the loading side plate 18 is open to the corrisponding ends of cylinders 24 at stations 26, 28, 30.
  • the opposite plate 20 is open to the corresponding ends of cylinders 24 at the unloading station 28 and squeezing station 30, while it shuts the end of that cylinder which is arranged in front of loading station 26.
  • the drum is driven to rotate by steps by a motor (not shown), in order to cyclically convey one cylinder in front of the loading station, another cylinder in front of the squeezing station, and the last cylinder in front of the unloading station.
  • loading station 26 comprises a pressing member 32, or any other suitable feeding device such as, e.g., a screw feeder, which is coaxial to cylinder 24 when the latter is positioned in front of the loading station, and is axially operable for conveying the material from a hopper 24 to the cylinder via a feeding duct 35.
  • a pressing member 32 or any other suitable feeding device such as, e.g., a screw feeder, which is coaxial to cylinder 24 when the latter is positioned in front of the loading station, and is axially operable for conveying the material from a hopper 24 to the cylinder via a feeding duct 35.
  • the rotation of the drum in order to convey the material from loading station 26 to squeezing station 30, causes the excess fraction of USW to be cut off by shearing between the adjacent surfaces of the cylinder and of loading side plate 18.
  • two pairs of tie rods 36, 38 connect the cross-pieces to each other at respective ends thereof along a longitudinal direction, against respective spacing members 40, 42 which are clamped between the cross-pieces, toghether with a plurality of removable, register spacers 44, 46.
  • Each tie rod is provided with threaded nuts 36a, 36b, 38a, 38b screwed to its opposite ends and abutting against the outer sides of the cross-pieces.
  • a middle portion L of each tie rod is surrounded by a heating sleeve 48 connected to power supply means (not shown).
  • Squeezing station 30 comprises a shutting piston (not shown), which is coaxial to the cylinder positioned in front of such station and sealingly closes its loading side end, as well as a pushing member or plunger 52 that is drivable by a hidraulic cylinder 54 to penetrate into cylinder 24 through the other end, thereby causing the material contained therein to be squeezed with its humid fraction drained through holes.
  • a shutting piston (not shown), which is coaxial to the cylinder positioned in front of such station and sealingly closes its loading side end, as well as a pushing member or plunger 52 that is drivable by a hidraulic cylinder 54 to penetrate into cylinder 24 through the other end, thereby causing the material contained therein to be squeezed with its humid fraction drained through holes.
  • unloading station 28 comprises a knockout piston 56 which is coaxial to that cylinder 24 positioned in front of such station, and is drivable by a hydraulic actuator 58 to penetrate into the cylinder through its loading side end and knock the compacted material out through the opposite end.
  • the knocked-out material is unloaded onto a chute (not shown) for removal.
  • the drum is driven to rotate by steps of 120° for cyclically subjecting each cylinder to:
  • a registering operation is periodically carried out, which consists of removing, after loosening the nuts, one or more register spacers 44, 46.
  • heating sleeve 48 is energized, thereby causing the tie rod to lengthen by thermal expansion, an then the nuts are tightened/loosened as desired.
  • FIG. 3 An alternative embodiment of the invention is shown in Fig. 3, where one of the nuts engaging the end of tie rod TI is substituted by an actuator 62 having a hollow, through piston rod 64 that is screwed to the end of the tie rod and abuts, with its bottom 62a on the side of the pressurized chamber, against the side of cross-piece TR.
  • Piston 64 is provided with a stop abutment 64a which abuts against the opposite bottom 62b of the cylinder with the cylinder in its home position.
  • abutment 64a moves away from bottom 62b so that spacers 66 can be inserted therebetween, in order to maintain the tie rod pre-tensionied at a desired value when the piston is depressurized.
