Shaft seal for a pyrolytic waste treatment system
View Patent ↗The inventive subject matter is directed toward a pyrolytic waste treatment system comprising a pyrolysis chamber having a chamber wall with a hole through which a shaft passes. An insulating mechanism is used at the hole to inhibit heat from escaping through the opening in the chamber wall.
1. A method for minimizing wear on a rotation shaft in a pyrolytic converter system, the method comprises:
Providing a pyrolytic chamber coupled to the rotation shaft wherein the rotation shaft is loosely mounted on a shaft support; and
providing a mount assembly having a compartment of deformable material surrounding and in contact with a port ion of the shaft wherein the deformable material is compressed between plates substantially perpendicular a centerline of the shaft and providing a sealing plate fixed to the shaft such that a translational movement of the shaft also moves the sealing plate, and wherein the sealing plate is disposed within the compartment.
2. The method of claim 1 further comprises allowing the sealing plate to move in a translational direction where the sealing plate deforms or compresses against the deformable material.
3. The method of claim 2 , wherein the deformable material is resilient and compressible.
4. The method of claim 3 , wherein the deformable material comprises two heat insulating blankets.
5. A pyrolytic waste treatment system, comprising:
a pyrolysis chamber;
a shaft passing through an opening in a wall of the chamber;
an insulating mechanism adapted to inhibit heat from escaping through the opening in the chamber wall while permitting the shaft to translate as well as rotate where it passes through the opening;
wherein the insulating mechanism comprises a first deformable and resilient blanket having a first hole that receives the shaft;
wherein the deformable and resilient blanket is made of a thermal insulating material that is compressible;
wherein the insulating mechanism further comprises a second deformable and resilient blankets having a second holes, wherein the shaft passes through the second hole; and the first and second deformable blankets are compressed between plates substantially perpendicular a centerline of the shaft.
