Definitions

• Figure 1 is a side elevational view partly in section showing a waste transfer system installed relative to a collection room located beneath the floor of a containment cell, with the port door closed and a storage vessel poised to be moved into docking position;
• Figure 15 is an underside view of the docking station
• Gear box 43 extends through the floor 24.
• Gear box 43 contains a plurality of interconnected gears 50.
• a drive shaft 52 is installed in gear box 43 on the collection room side of the floor 24.
• An electric motor 53 drives the drive shaft 52. Operation of the electric motor 53 moves the door 40 between the open and closed positions.
• FIG. 35 of Figure 4 installs in a standard unlined 55-gallon drum. Hazardous materials may require storage in a lined 55-gallon drum.
• Figure 5 shows a storage vessel 35 A for installation in a lined drum. The body portion 64A has a reduced diameter to accommodate the liner thickness of the lined 55-gallon drum.
• Figure 6 shows the port door 40 aligned for docking to the cover 73 of closed storage vessel 35. Port door 40 has a truncated conical body 75 ending in a reduced diameter neck 76. The closure face of port door is shown in Figure 9.
• a first connector set includes a perimeter of fastening ears 78 equally spaced about neck 76 and extending radially outward. Stop pins 83 extend inward from the ears 78 to the neck 76.
• cover 73 has a third connector set for connection to a fourth connector set on the open end of vessel 35.
• base 80 has a perimeter of notches 86 defining ears or tabs 87 which define the channel 74.
• vessel 35 has a fourth connector set that includes a perimeter of spaced apart ears 88 extending inward from neck 65. Ears 88 are spaced apart by notches 91 in correspondence to the spacing of the notches 86 on the inner face of the cover 73.
• Cover 73 is assembled to the vessel 35 with the ears 88 of vessel 35 passing between the notches 86. Vessel 35 is rotated relative to the cover so that the ears move into the channel 74 ( Figure 6A). Stop members 90 limit the relative rotation between cover 73 and the open end of vessel 35.
• Drive ring 110 is connected to a drive chain 115 by chain connectors 117 (see Figure 15).
• Chain 115 is trained through a gear box 120 ( Figure 15) connected to floor 24 and powered by docking drive motor 118. Operation of the chain 115 moves the drive ring 110 and causes the outer ring 94 to move relative to the inner ring 93.
• Motor 118 can drive chain 115 in clockwise or counterclockwise direction.
• the containment cell has a waste transfer port 28 defined in a floor 24.
• Floor 24 is located over a collection room 25.
• the port door 40 normally closes the transfer port 28 and is tightly seated therein to prevent contaminate leakage from the containment cell.
• the closure face of the port door faces the collection room.
• the drum 36 with the empty and closed vessel 35 is transported by a bogie 38 to a location beneath the transfer port 28.
• Drum lift 39 elevates the drum 36 and vessel 35 toward the docking station 33.
• the alignment lugs 71 are intercepted by the ramp surfaces between adjacent crown peaks on the docking ring assembly 92 as shown in Figure 13.
• the drum 36 is permitted to rotate on the bogie 38.
• the lugs are guided to a docked position into slots 97, 99.
• the ears 78 on the closure face of the cover 40 have passed through notches 84 on the outer face of the vessel cover 73 in a pre-interlock position as shown in Figure 7.
• the port door motor 53 is operated to move the port door away from the transfer port 28 to the port-door open position shown in Figure 3. In this position the outside face of the vessel cover 73 is tightly sealed against the closure face of the port door by the seal port door seal 79 so that neither is contaminated by the environment inside cell 22.
