Patent ID: 8671854

Claim:
A pyrolytic waste treatment system, comprising: a pyrolysis chamber; a shaft having a long, axis, and a portion that passes through, and rotates relative to, an opening in a wall of the pyrolysis chamber, and wherein the shaft has at least one of screw flights and paddles, extending radially outwards from the shaft within the chamber; a seal disposed to seal the opening, and to move in response to shaft movement, the seal being configured to entirely translate with longitudinal translation of the shaft with the seal being flat across an entirety of the seal; a first resilient insulating blanket surrounding the shaft and disposed to inhibit heat from escaping through the opening, wherein the first insulating blanket couples with the seal, the first resilient insulating blanket being flat across an entirety of the blanket in an undeformed state and disposed in a plane orthogonal to the long axis of the shaft, the first resilient insulating blanket being configured to deform with a radially interior portion of the first resilient insulating, blanket translating along a longitudinal axis of the shaft with the seal upon longitudinal translation of the shaft; and a compression device that compresses the first insulating blanket against the seal.
