In the field of glass manufacturing, the glass liquid is required to be melted at high temperature, because of the requirement of a manufacturing process, a fining agent containing tin is required to be added into the glass liquid, and because bubbles in the glass liquid are removed, the glass defects caused by the bubbles are reduced, but because the fining agent is very easy to volatilize under the high-temperature condition, the fining agent is condensed into crystallization at the place where the glass liquid is contacted with the outside when being cooled in the volatilization process. Cleaning the surface of the equipment, such as the outer wall of a stirring rod, a stirring barrel cover plate and the like. When the crystallization grows to a certain degree, the crystals fall into the molten glass due to the self-generated gravity and the like, so that the defects of stone bubbles and the like are generated, and the yield of the produced glass is reduced. Therefore, the devitrification needs to be cleaned regularly in daily production. However, since the stirring rod is required to stir, the devitrification adhered to the stirring rod is liable to fall off due to the rotation of the stirring rod, thereby causing the excitation of defects.
