Definitions

  • Compaction devices of this kind generally fall into two categories.
  • the first type compacts waste into paper or plastic bags whereas the second type compacts waste within a large steel bin.
  • a major disadvantage associated with compacting waste into bags is that the bags are generally small and require constant attention from a building attendant to replace the bags as they fill. This problem is overcome to some extent by arranging a series of empty bags on a carousel or linear conveyor for sequential filling.
  • Compaction of waste into large, wheeled, steel bins overcomes the problem of the need for constant supervision, but of necessity, the floor space required for horizontal ramming units is excessive whereas vertically operated rams are not applicable as there is insufficient headroom (usually only around 2.4 metres) in the basement area of a conventional high rise building.
  • Prior art reciprocating ram devices all suffer the disadvantage that rearward of the feed hopper, a considerable amount of floor space (or height in an analogous vertical unit) is required to enable retraction of the ram. In most units of this kind the distance is usually substantially the same length (or height) as the container into which waste is being compacted.
  • the provision of this "retraction space", at least in horizontally reciprocating devices causes the need for sloping feed chutes from a corner of the waste handling room where the chute usually enters from the ceiling.
  • the relatively low ceiling height approximately 2.4 metres
  • Most devices of this kind include a photo-electric cell positioned in the feed throat of the inclined chute to activate the reciprocating ram. Thus if waste was to lodge in the chute adjacent the P.E. cell, the ram would continue reciprocation leading to unnecessary wear on the compacting device and excessive power consumption.
  • the present invention aims to overcome or alleviate the problems of prior art waste compaction devices and to provide a simple robust and compact device suitable for high rise buildings.
  • a compaction device comprising:- a body member adapted for location in use over a waste collection bin; waste inlet means associated with said body member, oscillatable ram means located within said body for movement between a retracted position clear of said bin and an extended position to compact waste within said bin.
  • said ram means comprises a member pivoted about a transverse axis relative to said body member.
  • said ram means is pivotably mounted intermediate the length of said body.
  • said ram means is adapted, in the extended position to guide waste towards one end of said bin.
  • said ram is adapted to close said waste inlet means at a position intermediate the retracted and extended positions.
  • said body member is adapted for interlocking engagement with said waste collection bin.
  • said body member is adapted for elevated mounting on a frame member, said frame member being adapted to interlockingly engage said bin beneath said body member.
  • said inlet means is adapted for connection to a waste disposal chute.
  • FIG. 1 illustrates a side elevation of the compaction device.
  • FIG. 2 illustrates a support frame for the device of FIG. 1.
  • FIG. 3 is a front end elevation of the device shown in FIG. 1.
  • the device comprises a sturdy framework of suitable material such as rolled steel channel or the like.
  • the framework comprises a base 1 and an arch 2 located inwardly of the sides of base 1.
  • Pivotally mounted on the base 1 is a ram assembly 3 comprising a face plate 4 and a reinforcing framework 5 on the rear side thereof.
  • the ram assembly is shown in the retracted position and the extended position is shown in phantom.
  • Attached to the rear of ram assembly 3 are sector shaped plates 6 with a curved cover plate 7 extending therebetween to form a hood.
  • An hydraulic cylinder 8 is pivotally connected between the ram assembly 3 and frame arch 2 for movement of the ram assembly between its retracted and extended positions.
  • the ram assembly 3 is located within a body 9 supported on the base frame 1. At one end of the body 9 is an inlet chute 10 comprising a hopper 11 and a sloping throat 12. When the ram assembly is in the retracted position, face plate 4 serves as one of the walls defining the sloping throat 12 for guiding waste into the bin 13 shown partially in phantom. An inspection door 14 is provided in one or both sides of throat 12.
  • An electrically operated hydraulic pump 30 and an oil reservoir 31 are located within the body within the space bounded by the hood on the rear of the ram assembly when in the retracted position.
  • An electrical control panel 32 is provided suitably at one end of body 9.
  • a photo-electric cell 15 is provided in the region of the bottom of throat 12 to detect an accumulation of waste within the throat. Suitable timing delay circuitry is provided to ensure that the ram is activated only by a stationary accumulation of waste.
  • the ram assembly is clear of the bin thus permitting its removal and replacement by an empty bin.
  • throat 12 is closed by the hood attached to the rear of ram assembly 3 thus preventing waste from passing through throat 12 or into the region of the hydraulic controls.
  • the ram assembly is then returned to the retracted position allowing waste to fall into the bin.
  • the device is preferably provided with mechanical override means whereby the ram assembly can be cranked into position to close throat 12 and to permit removal of the bin.
  • the device according to the invention can be mounted directly onto a bin for mobile applications but preferably is fixedly mounted on an elevating frame to permit a bin to be wheeled underneath.
  • One end of the device is preferably stepped as shown to permit one lid of the bin to be folded into an open position.
  • FIG. 2 illustrates a side elevation of a preferred embodiment of an elevating support frame.
  • a bin (not shown) is wheeled from right to left in the illustration to engage at one end towards rear frame member 5.
  • Attached to front frame member 16 is pivotally attached a screw clamp device 17.
  • clamp member 19 is adapted to engage a slotted aperture in the bin to enable at least limited rearward and frontward movement under the influence of the screw clamp.
  • a base member 20 is provided to support the base of the bin during the compaction cycles.
  • lifting wedges 21, 22 lift the bin off the ground surface to prevent damage to the bin wheels and bearings resulting from the downward component of the compaction force.
  • the apparatus according to the invention is preferably adapted to be positioned in any of four corners of a basement waste handling room as waste chutes generally emerge from the ceiling in a corner due to building constraints.
  • the compaction device is preferably positioned directly below the chute outlet as inclined chutes give rise to problems of blockage and because of ceiling height limitations, any inclined chute is often at a low angle thus increasing the length of space required.
  • FIG. 3 is an end elevation of the device shown in FIG. 1.
  • Inlet 10 comprising hopper 11, has one sloping side 23 and at its lower extremities has a substantially square mounting flange 24 to permit the sloping side of the hopper to be positioned in any one of four directions relative to the length of the compacting device.
  • the width of the compaction device is preferably less than the waste collection bin and the elevating support frame of FIG. 2. In this manner, the device can be moved transversely relative to the frame and bin to enable alignment with and/or attachment to a waste chute in any of four corners of a confined space without wasting floor space.
  • the upper phantom outline illustrates a possible left to right movement with the inclined wall 23 of the hopper 11 rotated through 180°.
  • the lower phantom outline in the figure illustrates the ram assembly 3 in the extended position.
  • suitable infill panels are provided to seal the otherwise exposed portion of the bin aperture.
  • FIG. 3 also shows the control panel 32 in detail.
  • An operating switch 34 preferably key actuated to prevent unauthorized use, is positioned adjacent a "stop" button 35.
  • the apparatus may be put into operation by actuation of switch 34.
  • the operational mode of the apparatus is indicated by a first warning light 35a.
  • the pressure regulated control switch 33 shown in FIG. 1 is triggered by a "bin full” or overload condition, the hydraulic pump is electrically isolated and a second warning light 36 is illuminated and light 35 is extinguished.
  • the operator then actuates push button switch 37 to return the ram assembly to the horizontal position.
  • the operator actuates push button 38 to retract the ram assembly to its fully retracted position to allow accumulated rubbish to pass into the bin.
  • the present invention provides a compact device capable of compacting a large volume of waste yet occupying a minimum of floor space.
  • the waste collection bins may be urged into position by a lever, hydraulic rams or any other suitable means.
  • the bin may be suitably reinforced to avoid the need for support during compaction.
