High sealing shuttle kiln

Abstract

The utility model relates to the technical field of kiln, and disclose a kind of high sealing shuttle kiln, comprising: furnace body, the front and rear wall surface of furnace body are hinged with the seal door of reversible opening, the front and rear wall surface of furnace body is equipped with sealing groove;Sealing structure, sealing structure includes plugging piece, liquid inlet pipe and liquid outlet pipe, plugging piece is detachably installed in one side of seal door, plugging piece can be clamped into sealing groove and form seal, plugging piece is equipped with heat exchange cavity in its inside, plugging piece fixed installation liquid inlet pipe and liquid outlet pipe, plugging piece of spring steel material, utilize the thermal expansion characteristics of metal material, interference fit is formed with sealing groove under high temperature, realize the effect of "the hotter the more sealed", compared with rubber sealing element, sealing pressure is more stable, will not attenuate due to material aging, sealing reliability is greatly improved, metal plugging piece high temperature resistance, anti-aging, cooperate with efficient cooling system, the working temperature of sealing element can be controlled in safety range.
