In the production process of aluminum electrolysis, materials such as alumina, aluminum fluoride and the like need to be continuously supplemented into an electrolytic tank, and because the surface of a fused mass of the electrolytic tank is generally covered with a crust consisting of solidified electrolyte, the electrolytic tank needs to be pierced through the crust before charging, so that the materials enter the tank through an opened hole, the crust breaking device in the modern large-scale electrolytic tank is generally 2-8 or more, and the crust breaking system structure of each set of electrolytic tank is generally composed of hammer heads, hammer rods, air cylinders and the like.

However, in the existing traditional crust breaking structure, since the crust breaking system is a crust breaking impact structure, the hammer head needs to be broken into liquid electrolyte, so that the hammer head is quickly worn on one hand, and on the other hand, the hammer head is corroded by melt or electrochemically corroded due to contact of the hammer head with the electrolyte and even aluminum liquid;

and because the hammer head is often contacted with liquid electrolyte, the adhesion phenomenon is easy to generate, the electrolyte adhered to the surface of the hammer head can be continuously increased, and at the moment, the hammer head needs to be manually knocked by steel drills, so that the labor intensity of workers is increased, and on the other hand, the insulation or the sealing of the cylinder can be damaged due to vibration generated during knocking, so that the crust breaking structure capable of being replaced at any time and not influencing the driving cylinder is needed to solve the problems.
