Pressure vessel door seal mechanism
The invention relates to a pressure apparatus that can be used to process solid waste materials into useful, fuel and recyclable streams. The pressure vessel utilizes, conditions of heat and pressure to process the solid waste into the fuel and recyclable streams reducing hazardous materials and offensive odors. The vessel comprises an elongated container having enclosed volume and at least one open end. The open end is sealed using a closure having a closing apparatus. The closing apparatus is a rapidly actuated easily used mechanism that maintains the door in a sealed closed position maintaining useful pressure but can be readily opened with little effort for either removing processed waste or for introducing unprocessed solid waste.
1. A rotatable pressure vessel assembly having a closure, the vessel comprising an enclosed volume of about 30 to about 90 m 3 capable of maintaining an internal pressure of about 10 to about 4200 kPa, a temperature of about 20 to about 200° C. and a relative humidity up to about 100%, and the vessel defining a closure surface that cooperates with a closure to seal the vessel;
the closure comprising a circular door, and a split ring locking assembly, wherein the split ring locking assembly comprises a split ring and a means to change the diameter of the split ring, the split ring having a first diameter comprising a locked position and a second diameter comprising an unlocked position, where the first diameter is different than the second diameter;
a support frame having a bearing assembly configured to rotatable support the vessel; and
a hinge structure coupled to the support frame and the closure, wherein the hinge structure is configured to bring the closure into contact with the closure surface to seal the vessel.
2. The vessel of claim 1 wherein the split ring has an open diameter held entirely within the circular door.
3. The vessel of claim 1 wherein the split ring, when open, is held entirely within the vessel aperture.
4. The vessel of claim 2 wherein the closing diameter of the split ring is from about 1.8 to about 2.2 meters, while the open diameter is about 2 to about 2.5 meters.
5. The vessel of claim 3 wherein the closing diameter of the split ring is from about 2 to about 2.5 meters, while the open diameter is about 1.8 to about 2.2 meters.
