Rotary kiln seal
This patent describes a rotary seal apparatus to provide a positive seal between a rotating member and a non-rotating member. It comprises: a rotating disc plate attached to the rotating member; a nonrotating housing with an interior and an exterior surface, a plurality of seal bars linking the interior surface of the nonrotating housing with the disc plate; a preloaded spring means where the preloaded spring means is coupled to the connecting members; a first membrane joining an exterior surface of the primary housing to an external surface of the nonrotating member; a second membrane joining the primary housing with the secondary housing; a means for coupling an air supply and an air scavenge system to the nonrotating housing; a means for coupling an external support structure to the nonrotating housing; a means for preventing the rotation of the nonrotating housing which would result from a rotational torque generated by the frictional forces between the seal bars and the rotating disc plate.
