The Pot Tending Machine Crane is the key process equipment for the production of large-scale prebaked anode electrolytic aluminum. The crane can work in the environment containing HF corrosive gas, alumina powder, fluoride salt, carbon dust powder, asphalt smoke, high molten salt, and strong magnetic field. It has the functions of cracking electrolyte encrustation, replacing anode, adding alumina powder and electrolyte, lifting and transporting aluminum ladle and tapping water and slag, lifting the anode bus frame assists in lifting the anode bus, lifting the electrolytic cell and the upper structure of the cell during installation and maintenance, cleaning and soot blowing of the track, and sporadic lifting in the workshop.

Pot Tending Machine Crane for Electrolytic Aluminum is mainly composed of crane & trolley travelling mechanism, hydraulic and electric control mechanism, feeding mechanism, slagging mechanism, the anode replace mechanism, shelling mechanism and aluminium discharging mechanism.

The whole crane system adopts frequency conversion and PLC control. The operation adopts cabin room or remote control operation, and the two operation modes can cooperate with each other or be controlled independently. Pot Tending Machine Crane has been widely used in the electrolytic aluminum industry.

It can mainly used to complete the following task.

• Shelling. Open the electrolyte crust and add electrolyte such as alumina and fluoride salt to the electrolytic cell.

• Feeding. Adding electrolytes such as alumina and fluoride salt to the electrolytic cell.

• Replacing the anode. Unscrew the lifting and lowering and tighten the screw clamp, lift the residual electrode, and replace with a new anode.

• Unscrew the slag. Pull out the residual pole, remove blocks in the molten aluminum.

• Aluminum. Vacuum, aluminum tapping, lifting and weighing (single bag and accumulation) and display, implement printing.

• Lifting. Lifting anode busbar hoisting anode busbar lifting frame.

• Maintenance. Complete the installation and maintenance of the upper structure and lower tank shell of the electrolytic cell and other sporadic lifting.
