Definitions

  • the present disclosure relates to a waste compression arrangement, and especially to a waste compression arrangement comprising a hydraulic cylinder.
  • Waste compactors are used for compressing waste. At locations with limited space, such as in small shop storage rooms, it is useful to be able to compress the waste to free space. At the same time is it important that the waste compactor itself is not too bulky.
  • a vertical waste compactor occupies a relatively small floor space and comprises a waste container for receiving waste and a compression plate for compressing the waste. On top of the waste container there is arranged one or two hydraulic cylinders to press the compression plate downwards to compress the waste in the waste container.
  • waste compactor is still too bulky, for instance due to the height of the waste compactor.
  • the size of the waist container needs to be reduced in order to enable the waste compactor to fit in the room.
  • a waste compression arrangement according to claim 1.
  • the arrangement comprises a bottom plate, a waste container arranged on the bottom plate, a compression plate for compressing waste in the waste container, and at least one hydraulic cylinder for moving the compression plate.
  • the hydraulic cylinder is arranged with a first end attached to the bottom plate, and a second end attached to the compression plate. The hydraulic cylinder may thereby pull the compression plate downwards to compress waste in the waste container.
  • the at least one hydraulic cylinder may be configured to contract when pulling the compression plate to compress waste in the waste container.
  • a waste compression arrangement according to the present invention may enable a larger waste container volume than a previously known waste compactor of the same height.
  • a waste compression arrangement according to the present invention may have a minimum height that is equal to the height of side walls of the waste container. Such arrangement may thereby be easier to transport, both due to the height and due to a lower centre of gravity of the arrangement.
  • a waste compactor of known type with hydraulic cylinders arranged on top of the waste container may have a height of about 3.2 meters from a bottom plate to the end of the hydraulic cylinders.
  • a waste container may have a height of about 1.5 meters, i.e. the height of the space for receiving waste.
  • a waste compression arrangement, such as a waste compactor, according to the present invention with a correspondingly sized waste container may have a height of about 2.4 meters when the compression plate is in its top position, i.e. at maximum size of the waste container.
  • the waste compactor when the compression plate is in an intermediate position, the waste compactor may have a height of about 2 meters.
  • the height of the waste compactor in the intermediate position may correspond to the height of side walls of the waste compactor.
  • the arrangement of the present invention may thereby provide a waste compactor of reduced height compared to known arrangements.
  • the minimum height in the intermediate position may further provide a reduced height when transporting the waste compactor.
  • the first and second ends of the at least one hydraulic cylinder may be opposite remote ends of the hydraulic cylinder.
  • the hydraulic cylinder may, at its opposite remote ends be attached to the compression plate and the bottom plate.
  • the hydraulic cylinder may comprise a cylinder body and a piston rod, and one of the cylinder body and the piston rod may be attached to the bottom plate and the other to the compression plate.
  • a guide means for each hydraulic cylinder may be integrated in a side wall of the waste container.
  • each hydraulic cylinder may be arranged with a guide means.
  • the guide means may be integrated in the side wall of the waste container.
  • the hydraulic cylinder may extend from the bottom plate along a side wall of the waste container.
  • the guide means integrated in the side wall may be a channel in the side wall.
  • the hydraulic cylinder may thereby be arranged in said channel.
  • the guide means may alternatively be a guide rail, a rim, a groove or the like, integrated in the side wall.
  • the hydraulic cylinder may in a second end be coupled to the compression plate by a coupling means.
  • the coupling means may be adapted to connect the piston rod of the hydraulic cylinder to the compression plate.
  • the coupling means may be fixed to the compression plate and configured to be coupled to the hydraulic cylinder.
  • the coupling means may be an integrated extension of the compression plate.
  • the coupling means may be releasably fixed to the compression plate.
  • a side wall of the waste container may comprise an inner side surface at least partly covering the hydraulic cylinder, and the inner side surface may comprise an opening for receiving the coupling means between the second end of the hydraulic cylinder and the compression plate when the compression plate is moved to compress waste in the waste container.
  • the compression plate When the compression plate is pulled downwards, to press waste in the waste container, the position of the compression plate may be below a top edge of the side walls of the waste container.
  • the coupling means connecting the compression plate to the hydraulic cylinder may then extend through or crossing a part of the side wall.
  • An inner side surface of the side wall may cover at least a part of the hydraulic cylinder, separating the hydraulic cylinder from the waste container.
  • the side wall may comprise an opening.
  • the opening may be configured to receive the coupling means when the compression plate is pulled into the waste container.
  • the opening may be formed as a slot, or an elongated opening, extending from the top edge of the side wall.
  • the coupling means may comprise a tube arranged to enclose the second end of the hydraulic cylinder.
  • the second end of the hydraulic cylinder may comprise a piston rod.
  • the tube may then enclose an end of the piston rod.
  • the tube may provide an improved stability of the hydraulic cylinder, especially in its extended position when the piston rod extends out of the side wall of the waste container. Further, when the piston rod extends out of the side wall, the tube provides a safety feature of preventing anything from being squeezed between the piston rod and the side wall when the hydraulic cylinder contract.
  • the arrangement may comprise two hydraulic cylinders arranged in respective opposite side walls of the waste container.
  • Each side wall may comprise a channel for guiding the hydraulic cylinder, in which the hydraulic cylinder may be arranged.
  • the waste container may comprise two opposite side walls and a back wall connecting the two side walls.
  • the waste container may further be defined by the bottom plate, the compression plate on top and a front. The front may at least partly be a door for discharging waste from the waste container.
  • the two hydraulic cylinders may be coupled to the compression plate and together arranged to pull the compression plate to compress waste.
  • the two hydraulic may be arranged to be coupled to the compression plate at respective opposite sides of the compression plate. Both hydraulic cylinders may be coupled to the compression plate by means of respective coupling means.
  • Such arrangement may provide a stabile compression arrangement.
  • the coupling means may comprise two tubes arranged to enclose each second end of the hydraulic cylinders respectively.
  • Fig. 1 illustrates a waste compactor 1 according to an embodiment of the present invention comprising a bottom plate 10 onto which the waste compactor 1 stands on a floor.
  • the bottom plate 10 also forms a bottom of a waste container 20.
  • the waste container 20 is further formed by two opposite side walls 22 and a back wall 24.
  • the open front of the waste container may in an embodiment be covered by an openable discharge door (not shown) for discharging waste compressed in the waste container 20.
  • the waste compactor 1 further comprises a compression plate 30 arranged for compressing waste in the waste container 20 when being moved downward, into the waste container 20.
  • Figs. 2 and 3 illustrate the waste compactor 1 in cross-section.
  • the compression plate 30 is suspended by two hydraulic cylinders 40.
  • the hydraulic cylinders 40 are arranged in the side walls 22 of the waste container 20.
  • Each side wall 22 comprises a channel 28 in which the hydraulic cylinders 40 are arranged.
  • Each channel 28 is open at a top end of the side wall 22.
  • Each hydraulic cylinder 40 comprises a cylinder body 42 and a piston rod 44.
  • the cylinder bodies 42 are attached to the bottom plate 10 at a first end 46 of each hydraulic cylinder 40.
  • the cylinder bodies 42 extend from the bottom plate 10 through the channels 28.
  • the piston rods 44 are attached to the compression plate 30 at a second end 48 of each hydraulic cylinder 40.
  • the compression plate 30 is attached to the piston rods 44 via a coupling 32.
  • Fig. 2 illustrates the compression plate 30 being in a top position.
  • the hydraulic cylinders 40 are extended to a maximum axial length.
  • the piston rods 44 extend out of the channels 28 in the side walls 22 through channel openings 29 (see fig. 3 ).
  • the volume of the waste container 20 is maximized to receive waste to be compressed.
  • the hydraulic cylinders 40 pull the compression plate 30 downward.
  • the piston rods 44 move downward into the cylinder bodies 42 and pull the compression plate 30 downward.
  • the compression plate 30 is illustrated in its bottom position wherein the piston rods 44 are moved to a contracted position of the hydraulic cylinders 40, providing the hydraulic cylinder 40 with its minimal axial length.
  • a hydraulic cylinder 40 has a higher stability and strength in its contracted position compared to its most extended position. It is therefore an advantage that the compression plate 30 is moved towards its bottom position by the hydraulic cylinders 40 contracting, when the highest amount of acting forces is present, i.e. when waste is being compressed in the waste container 20.
  • the coupling 32 between each hydraulic cylinder 40 and the compression plate 30 further comprises tubes 34 enclosing each piston rod 44 respectively.
  • the tube 34 extends along substantially the entire axial length of the piston rod 44. In the most contracted position of the hydraulic cylinder 40, the tube extends from the end 48 of the piston rod 44 to the end 46 of the cylinder body 42.
  • the tubes 34 provide an improved stability of the hydraulic cylinders, especially in its extended position when the piston rods 44 extend out of the side walls 22. Further, when the piston rods 44 extend out of the side walls 22, the tubes 34 provide a safety feature of preventing anything from being squeezed between the piston rods 44 and the side walls 22 when the hydraulic cylinders 40 contract.
  • the side wall 22 of the waste container 20 comprises an opening or a slot 26.
  • the opening 26 extends from a top edge of the side wall 22 and downward.
  • the opening 26 is configured to receive the coupling 32 between the hydraulic cylinder 40 and the compression plate 30 when the compression plate 30 is moved downward.
