ABSTRACT:
A combination liquid seal and spiral auger conveyor feeding system which provides both a liquid seal, effective under normal operating conditions, with a sealed spiral auger conveyor, which is effective to seal against the surge flow of distillation gases back through the feeding system. This is attained while providing for a reliable, continuous flow of solid bulk material such as rubber tire chips to a reactor or distillation unit. A bulk feeding system having a partially submerged inclined spiral auger conveyor is provided, communicating at its base with a liquid reservoir so as to form a liquid seal within the combined apparatus. Solid bulk material is introduced to the upper end of the liquid reservoir above the liquid level where it descends by the action of gravity into the liquid and sinks to the bottom of the reservoir to by picked up by the partially submerged rotating auger conveyor and elevated thereby. The bulk material is raised above the liquid level and introduced to the reactor or distillation unit inlet. The requirement of a small clearance between the flights of the auger and its cylindrical wall, along with the presence of the bulk material being conveyed within the auger, acts as a seal against distillation gas surges, thus avoiding fires and explosions in the bulk material storage and conveying apparatus.
