Microwave decomposition machine with output door mechanism

Abstract

An output door mechanism for a microwave decomposition machine allows a rotating tank to be coupled to a fixed waveguide with both a vacuum and a microwave seal. The fixed waveguide delivers microwave power to the rotating tank in a decomposition machine. A moveable end cover joins the rotating tank to the fixed waveguide providing the rotating tank with a vacuum and microwave seal during the decomposition of material and discharge of the tank after the decomposition has been completed. The output door mechanism uses a rolling bearing to form a rolling seal, a sliding bearing to form a sliding seal, and a metallic bellows to form a flexible seal. A plunger compresses a spring to seal the end cover to the rotating tank. When the plunger no longer applies compressive force to the spring the end cover separates from the rotating tank to allow discharge of the decomposed material.
