Definitions

  • the present invention therefore relates to a feeder arrangement for an incinerator that precludes the passage of smoke therethrough from the housing enclosing a chamber having an incomplete combustion of refuse placed therein.
  • the invention generally provides for an arrangement of cooperating feeder members or pivoted doors, one of which is continuously covered by an imperforatesealing cover while the other thereof is adapted to compress a mass of refuse or trash sufliciently to offer a substantial resistance to the passage of gas therethrough.
  • the refuse is compressed in a confined hopper or passageway to the incinerator and is arranged in the feeder to offer increased resistance to the flow of gas as the compaction of material being moved therethrough increases.
  • the feeder door having the sealing cover is normally closed to preclude 3,486,644 Patented Dec. 30, 1969 the leakage of smoke therethrough, but as it opens the compaction of refuse in the hopper increases its reslstance to the leakage of smoke so that the smoke and gases generated in the housing have little chance of escaping to the atmosphere.
  • FIGURE 1 is a perspective view of the loading mechanism attached to an incinerator housing
  • FIGURES 2, 3, and. 4 are schematic drawings indicating various steps in the operating sequence of the device of FIG. 1.
  • the numeral 10 indicates the housing of an incinerator having a loading port or opening 12 through which the incinerator is to be charged with trash or refuse.
  • a loading door or ram 14 is pivoted at 16 at the upper edge of the opening 12 whereby it is adapted to swing downwardly over arcuate compaction door 36 and advance refuse compacted thereby into the incinerator and close the opening to the flow of gas and smoke.
  • An arcuate hopper 26 is arranged with an axial edge 28 thereof aligned with the bottom edge of the port 12 in the housing 10.
  • the hopper 26 is arranged to tightly abut the housing adjacent the port to preclude the leakage between abutting members of gases generated within the incinerator.
  • An end plate 30 abuts each end of the arcuate hopper 26 and extends vertically along the lateral sides of the port 12 to provide end walls for the hopper and walls adjacent opposite ends of the loading door 14.
  • An imperforate cover plate 22 abuts the housing 10 along one edge thereof over the port 12 and extends diagonally downward at a declination of about 45 to the approximate lateral midpoint of the end plates 30 to provide a cover over the loading door 14 as it is moved to an open position and thus preclude the escape of gas and smoke from the incinerator directly to the atmosphere.
  • the end plates 30 support bearing means at either end position at the projected center of the arcuate hopper 26.
  • a compaction member 36 secured to a rod 38 is rotatable in the bearings of the end plates so that it may rotate in the arcuate hopper 26 and from the load position shown in FIG. 2 to a feed position shown in FIG. 4 whereby trash placed in the hopper 26 may be advanced or fed to the incinerator by the loading door 14. As the trash is so advanced it is also compressed so that it offers increased resistance to fumes escaping from the open incinerator port 12 back through the refuse being fed through the hopper.
  • the hopper 26 may be secured to the housing 10 of the incinerator as a permanent accessory or it may be mounted on suitable rollers or casters 52 whereby it may be temporarily moved into position adjacent the housing 10 and used as needed.
  • control apparatus responsive to movement of the compaction member 36 within the hopper 26 and the loading door 14 may be adapted to operate the respective members in the proper sequence desired.
  • control apparatus may be designed to operate in response to movement of plate 36 to provide for complete opening and closing of the loading door.
  • switching means may be actuated by the arm 52 on the shaft 38, while the relative movement of the several members is dependent upon a predetermined sequence desired.
  • the operating sequence is started by a complete closure of the loading ports 12 by loading door 14 and a complete opening of the hopper 26 by movement of the compaction door 36 to an extreme upper position shown in FIG. 1 whereby a load of trash or rubbish may be placed into the hopper without interference with the compaction door.
  • the compression member 36 is actuated by closure of the proper controls 37 and the motor means 40 accordingly acts through transmission means 42 to rotate the member 36 about its axis or pivot 38 to slowly compress the trash in the hopper 26.
  • a circuit in a conventional timer 46 is completed and the loading door 14 of the incinerator is actuated by motor 44 to move it to an open position. The door 14 is thus moved to an open position whereby the lower edge thereof lies adjacent the compaction member.
  • the compaction door 36 continues to rotatably swing on its pivot 38 until it lies adjacent the lower edge of por 12, whereupon suitable switching means in controller 46 is operated to Open the circuit to operating means 40 and thus terminate movement of the compaction member 36 and commence actuation of the operating means 44 and the connected loading door 14.
  • suitable switching means in controller 46 is operated to Open the circuit to operating means 40 and thus terminate movement of the compaction member 36 and commence actuation of the operating means 44 and the connected loading door 14.
  • the loading door 14 closes it sweeps the compacted refuse resting upon the compaction door 36 through the port 12 and into the incinerator housing 10.
  • the compaction member Upon closure of the port 12 by door 14 the compaction member is returned to its open position whereby trash may again be loaded into the hopper 26 in preparation for another feeding cycle.
  • an incinerator comprising a housing with a loading port at one side thereof, a collection hopper with an arcuate bottom surface adjacent the loading port of the housing, an arcuate compaction member pivoted at the projected center of said arcuate hopper, means for ID- tating the compaction member about its pivoted support within the hopper to compress rubbish placed in the hopper, a loading door pivoted on the incinerator housing and arranged to close the loading port, said loading door pivotally attached to said incinerator and having an arcuate movement substantially concentric to the arcuate surface of the compaction member, means for moving the loading door about its axis, and imperforate means cooperating with said loading door adapted to direct fumes from the incinerator through the collection hopper and the rubbish compressed therein when the loading door is moved to open the loading port of the incinerator.
  • An incinerator as defined in claim 1 wherein the imperforate means cooperating with the loading door of the incinerator comprises a cover plate that abuts the incinerator housing adjacent the pivot for the loading door and extends to a point adjacent the pivot for the compaction member.
  • an incinerator having a housing with a loading port at one side thereof, a collection hopper with an arcuate bottom surface adjacent the loading port, an arcuate compaction member pivoted to fixed support at the projected center of said arcuate hopper, means for rotating the compaction member about its axis within the arcuate hopper to compress rubbish placed in said hopper, a loading door arranged to close the loading port, said loading door pivotally attached to said incinerator and having an arcuate movement similar to the arcuate surface of the compaction member, means for moving the loading door about its axis, and cover means over said loading door adapted to direct fumes from the incinerator' through the collection hopper and the rubbish compressed therein when the loading door is moved to open the loading port of the incinerator.
