Description

Aluminum electrolysis crust breaking hammer head

Technical Field

The modern aluminum industry adopts cryolite-alumina molten salt electrolysis method to produce aluminum. In the method, molten cryolite is used as a solvent, alumina is used as a solute, a carbon body is used as an anode, aluminum liquid is used as a cathode, and after strong direct current is introduced into the solution, electrochemical reaction is carried out on two poles in an electrolytic cell at 950-970 ℃, namely, aluminum is electrolyzed. As the electrolytic reaction proceeds, alumina in the electrolytic solution is gradually consumed, and thus, it is necessary to continuously supply alumina to the electrolytic solution. Because the heat preservation measure among the electrolysis process, the covering material and the electrolyte of the electrolyte in the electrolysis trough furnace can solidify to form the crust and wrap up electrolyte, in order to guarantee that aluminium oxide can be smooth and easy to add electrolyte, need keep a hole open in the charging means position before reinforced. At present, crust breaking is generally carried out on the formed crust surface by adopting a crust breaking hammer head in industrial production so as to open holes needed by adding alumina feed liquid.

On one hand, when the crust breaking down operation is carried out, only the crust breaking down operation can be carried out, if the blanking hole is inclined, the crust cannot be smoothly broken to reach the blanking hole, and the blanking hole is gradually covered by crust-forming alumina to be blocked; on the other hand, when the hammer head is subjected to long-term crust breaking operation, the electrolyte solution gradually corrodes and is consumed to a shorter extent, and when the electrolyte solution is not reached, the hammer head needs to be replaced. When traditional crust-breaking hammer was changed at every turn, all need hang whole cylinder and hammer stem from the groove and get off, hang to go the installation after changing again. Therefore, the labor amount for overhauling the hammerhead is large, and safety risks such as high-altitude operation, hoisting operation and the like exist during operation.
