Description

Technical Field

[0001] This utility model relates to the field of automatic lubrication technology, and more specifically, to an automatic lubrication device for the main rotating gear of an electrolytic aluminum ball mill. Background Technology

[0002] Electrolytic aluminum is aluminum obtained through electrolysis. Modern industrial electrolytic aluminum production uses the cryolite-alumina molten salt electrolysis method. Molten cryolite is the solvent, alumina is the solute, carbonaceous material is the anode, and molten aluminum is the cathode. A strong direct current is applied, and an electrochemical reaction occurs at the two electrodes in the electrolytic cell at 950℃-970℃—this is electrolysis. Ball mills are key equipment for further pulverizing materials after they have been crushed. This type of grinding mill contains a certain number of steel balls as grinding media inside its cylinder.

[0003] During the operation of an electrolytic aluminum ball mill, the main rotating gear is under heavy load and requires regular daily lubrication. Insufficient lubrication can cause severe gear wear, resulting in misalignment and breakage. Most existing ball mill lubrication devices are complex in structure, making it inconvenient to add oil at regular intervals and in precise quantities daily. Their practicality and safety need improvement. Furthermore, a utility model patent with publication number CN219734965U discloses an automatic lubrication device for a ball mill, which includes a ball mill body. A large and small gear connecting assembly is provided on one side of the ball mill body. A boat-shaped box is provided below the large and small gear connecting assembly. A fixing plate is installed on one side of the boat-shaped box. A motor is fixedly installed on the top side of the fixing plate. The output shaft of the motor passes through the fixing plate and is fixedly connected to the lubrication assembly. Its structure is complex and inconvenient for lubricating the main rotating gear in the enclosed area inside the electrolytic aluminum ball mill. Utility Model Content
