Patent ID: 7743912

Claim:
A liquid sealed conveyor apparatus for continuously feeding particulate material, such as chips of used automobile tires, to a reactor or distillation unit while maintaining a seal against the exchange of distillation gases and atmospheric air comprising: an inclined pusher auger having an outlet at a lower end thereof and an inlet; an inclined feed auger having an inlet at a lower end thereof and an outlet at an upper end thereof, said feed auger inlet being connected to and in liquid communication with said pusher auger outlet; said pusher auger and said feed auger being partially filled with a liquid to an operating reservoir liquid level and an operating feed auger liquid level, respectively, wherein said pusher auger inlet is above, and said pusher auger outlet is below, said operating reservoir liquid level; whereby action of the rotation of said pusher auger pushes particulate material entering said pusher auger inlet into said liquid, beneath said operating reservoir liquid level and to said feed auger inlet, and whereby the particulate material then is engaged and transported by action of the rotation of said feed auger to a point above said feed auger liquid level, and is discharged through said feed auger outlet for delivery to said reactor or distillation unit.
