Definitions

  • the invention is in the field of commercial balers, and also in the field of sohd hazardous waste disposal.
  • Hazardous Waste is solid, hazardous waste ofthe type which must be disposed of in corrugated cartons approved by the United States Department of Transportation.
  • a carton is referred to in the industry as a "Cecos Pack”. It is made of tn- walled corrugated board, 36 inches on a side, lined with six mil polyethylene film. When full, the polyethylene liner is sealed, the carton is closed and sealed with duct tape, and is manifested in detail, ready for shipment to an authorized landfill.
  • Carton refers to a carton specified for Hazardous Waste by the DOT as above.
  • Hazbaler in what follows refers to a vertically disposed, manually fed industrial baler modified to load cartons with dense bales of Hazardous Waste weighing 350 to 500 pounds. It is designed to accomplish this in an environment of negative air flow.
  • Cartons are expensive and filling them with Hazardous Waste, by hand or conveyor, as presently done, is time and labor consuming. Cardboard boxes, plastic pails, and the like, waste much ofthe carton's capacity; transportation is charged per carton, not per pound. If the Hazardous Waste were to be first compacted, as by baling it, before it is loaded into the carton, the carton's capacity would be increased by as much as sixfold, and substantial savings thereby realized.
  • An object ofthe invention is to provide means for making a bale of Hazardous Waste, elevating the finished bale, and lowering the bale into a carton.
  • a further object ofthe invention is provide means for making a bale of Hazardous Waste and loading the bale into a carton in an environment of negative airflow.
  • the finished bale must be elevated in the baler to allow positioning of a carton beneath the bale, so that the bale can be lowered into the carton; and. the bale must be made smaller than the bale chamber in which it was made, to allow clearance around its periphery for the walls ofthe carton.
  • the Hazbaler provides retractable sidewalls within which a bale of Hazardous Waste is formed and tied with wires. Grooves on the upper surface ofthe Hazbaler platen accommodate lifting wires. After the bale is finished and the lifting wires secured, the platen rises slightly, relieving pressure on the bale; a positioning device moves the bale forward slightly; and the platen rises to its upper limit, lifting with it the retractable sidewalls and the new bale of Hazardous Waste. The sidewalls latch in the retracted position. The operator positions an open carton beneath the bale, and presses a control. The platen descends, inserting the bale in the carton. The operator cuts the lifting wires (leaving them in the carton), and presses another control. The platen rises again; the operator removes and seals the carton with the bale in it.
  • the Hazbaler may be enclosed in a negative airflow environment with limited access for manipulating the bale and the carton.
  • the Hazbaler enables inserting into a carton, in a negative airflow environment, many times the weight of uncompacted Hazardous Waste that it would otherwise accommodate.
  • Figure 1 is a schematic sketch in cross section through the front of a vertical baler modified for baling and packaging hazardous waste.
  • FIG. 2 is a schematic sketch in cross section through the side ofthe baler of Figure 1.
  • Figure 3 is a front view ofthe Hazbaler fitted with an exhaust blower for maintaining air flow through the Hazbaler, so that noxious dust and vapors cannot escape into the local environment.
  • FIGS 4 through 8 are cross sections of the hazardous waste baler showing sequential steps in its operation. DESCRIPTION OF A PREFERRED EMBODIMENT
  • FIGS 1 and 2 illustrate schematically the operative parts of a vertical baler adapted for baling and packaging hazardous waste in cartons. The view is ofthe baler positioned to start a new baling sequence.
  • sidewalls 1, the back wall ofthe baler 2, the baler floor 3, and the door 4, shown cut away, and the platen 5 define a cavity - the bale chamber - in which the bale of waste is formed.
  • the platen driven by hydraulic cylinder 6 and piston 7, repetitively squeezes waste tossed into the cavity between strokes ofthe platen.
  • the conventional baler is modified to provide for loading the completed bale into a carton.
  • the modifications comprise false sidewalls 10, which move vertically in guides (not shown) in sidewalls 1.
  • the false sidewalls have latch-receivers, shown in this embodiment as holes; there are two latch- receivers in each false sidewall, positioned to receive latches mounted . respectively on the platen (1 1) and on the sidewalls (I T, Figure 2).
  • the latches are represented by hydraulic cylinders 12 mounted on the platen, and 13 mounted on the sidewalls.
  • two additional wire guides 14 are provided on the top ofthe platen 5 for lifting wires.
  • Wire guides 14' ( Figure 2) on the back ofthe baler are aligned with grooves 14 in the top ofthe platen and with grooves 14" in the baler floor.
  • Means are provided in the back wall 2 ofthe baler for shoving the completed bale forward, as it hangs from the platen by the lifting wires, so that the bale will line up with the carton (this arrangement is described in detail below).
  • the bale shoving means are hydraulic cylinders 16 and pads 15 ( Figure 2) mounted on the back wall ofthe baler. Pads 15 are shown in Figures 4 through 8 as phantom squares in the back wall ofthe Hazbaler.
  • Figure 3 is a view ofthe Hazbaler seen from in front.
  • the Hazbaler is enclosed, except for the area above the door into which waste is loaded, in sheet metal.
  • An exhaust fan 19 is mounted on the top ofthe Hazbaler. It is of a capacity to maintain a negative pressure inside the baler, so that any hazardous .dust or vapors are drawn through the Hazbaler and exhausted by the fan.
  • FIGS. 4 - 8 cross-sections through the baler parallel with the front ofthe baler, illustrate the sequence of operation.
  • the bale is about to be formed.
  • Door 4 is closed.
  • False sidewalls 10 disengaged from the latches, rest on the baler floor, so that the bale will be of a length to fit into the carton.
  • the operator tosses waste into the baler behind the door, repetitively causing platen 5 to squeeze the waste he has added, until the compressed waste has attained sufficient height to fill a carton. At that point, the platen will be lowered and the waste compressed, and the door will be opened.
  • FIG 5 shows the state ofthe baler after the operator has run his tie wires 17 around the bale through the tie-wire guides described above, and has tied them off, the door (not shown in this view) being open. False sidewalls 10 still rest on the floor ofthe baler.
  • FIG 7 shows the baler about to lower the bale into carton 18.
  • the operator has caused the platen to rise high enough to allow him to position carton 18 beneath the bale; the false sidewalls 10, being latched to platen latches 12, have risen with the platen, leaving room at the sides for the carton to fit beneath the bale.
  • Pusher plates 15 Figures 1 and 2) have been activated by cylinders 16 ( Figure 2) in the back wall, shoving the bale slightly forward, providing clearance for the back wall ofthe carton positioned beneath it.
  • the bale has been lowered into carton 18.
  • the operator will extract carton 18 with the bale in it, and will seal it as required with duct tape. Then he will cause the platen to rise again; platen latches 12 will engage the false sidewalls; frame latches 13 will disengage; the platen will descend, carrying the false sidewalls; platen latches 12 will disengage, leaving the false sidewalls in place in the bale chamber; and the platen will rise again, restoring the baler to the state illustrated in Figure 1 , ready for a new cycle.
  • pusher plate 15 and cylinder 16 are not used. Instead, clearance for the back wall ofthe carton is provided by a false back wall attached at its edges to the false sidewalls 10, so that the whole assembly, false sidewalls and false back wall, rise as a unit when platen latches 12 engage latch receivers 1 1 in the false sidewalls 10.

Abstract

La présente invention concerne une presse à balles (2) comportant des fausses parois latérales (10) servant de parois de butée dans la chambre de mise en balle pendant l'accumulation des constituants de la balle. Une fois l'accumulation terminée, des taquets (12) équipant le plateau (5) s'enclenchent dans les fausses parois latérales (10). La remontée du plateau (5) provoque la remontée de ces fausses parois latérales, qui restent en position relevée sous l'effet des taquets (13) des parois latérales (1) de la presse à balles alors que le plateau (5) descend et comprime la balle. La balle est ficelée (17) sur le plateau (5), qui, en remontant, extrait la balle par le haut de la chambre de mise en palle; ce qui permet d'introduire un carton (18) dans la chambre (ouverte) de mise en balle. Le plateau (5) redescend et dépose la balle dans le carton (18). Une fois que les ficelles de ficelage (17) sont coupées, le plateau (5) remonte, puis le carton (18) est fermé de façon étanche et retiré de la chambre de mise en balle.
