Pressure-free refractory coating leaching device for evanescent mode

The invention discloses a pressure-free type refractory coating leaching device for an evanescent mode, and belongs to the field of refractory coating coating equipment. The pressure-free type refractory coating leaching device abandons a traditional clamping-pressing soaking mode, adopts a mode that the evanescent mode freely floats on the liquid level of a refractory coating and is combined with a means that the refractory coating is poured from top to bottom; meanwhile, the poured refractory material can generate certain impact force on the evanescent mode, the gravity center of the evanescent mode floating freely is unstable, the evanescent mode automatically floats and shakes on the liquid level, the pouring position is changed, and in the evanescent mode floating process, the evanescent mode is automatically floated and shaken through the buffering and rebounding effects of the rebounding arc on the evanescent mode, so that the evanescent mode is prevented from falling off.
