摘要：A rotary isolation door for use in a conduit extending between an auger feeder and an incinerator which opens to allow the auger feeder to convey material to the incinerator and closes to prevent burn-back of material in the conduit from the incinerator. The door includes a first housing plate having a first opening offset from its center, An annular spacer-plate attached to the first housing plate, and a second housing plate having a second opening offset from its center and attached to the side of the spacer plate opposite the first housing plate. The first, second and spacer plates are attached to form an interior chamber within which is rotatably mounted a door plate having an offset opening such that a flow path is formed when the openings of the first and second housing plates and door plate are aligned. The door plate is fixed to a central drive shaft which is rotatably supported by the housing plates, and is rotated by cylinder motors pivotably attached to a lug extending sidewardly from the spacer plate. A lubrication system injects a lubricant into the interior chamber under pressure so that lubricate flows radially outwardly to the flow path to minimize accumulation of particulate contaminants within the interior chamber.
