Multifunctional Crane For Electrolytic Aluminum: Fulfills All Aluminum Electrolysis Processes, Boosts Plant Efficiency

Multifunctional crane for electrolytic aluminum, also known as a Pot Tending Machine (PTM), is a key process equipment in large-scale prebaked anode electrolytic aluminum production. This Multifunctional crane for electrolytic aluminum can withstand the special environments of high temperature, high current, strong magnetic fields, high dust levels, and HF (hydrogen fluoride) fumes.

Multifunctional crane for electrolytic aluminum is composed of main trolley traveling mechanism, crane bridge, Tool Trolley, Aluminum Tapping Trolley, hydraulic and pneumatic system, and electrical control system. Its core component is the Tool Trolley, which specifically includes trolley traveling mechanism, trolley frame, tool slewing mechanism, Crust Breaking Mechanism, anode changing mechanism, slag removal mechanism, batching mechanism, and operator cab slewing mechanism. The entire Multifunctional crane for electrolytic aluminum adopts frequency conversion + PLC control and supports two operation modes: Crane Operator Cab operation and remote control, serving as a dedicated equipment covering all electrolytic processes.

Functions of Multifunctional Crane for Electrolytic Aluminum

As a key process equipment for large-scale prebaked anode electrolytic aluminum production, the multifunctional crane for electrolytic aluminum can adapt to special environments such as high temperature, large current, strong magnetic field, high dust, and HF flue gas. It can complete the following process operations of prebaked anode electrolytic cells:

• Crust Breaking: Break the electrolyte crust to add electrolytes such as alumina and fluoride salts into the electrolytic cell.
• Feeding: Add electrolytes such as alumina and fluoride salts into the electrolytic cell. With high-precision metering devices, precisely control the feeding amount as required to stabilize electrolyte composition and ensure efficient continuous electrolysis.
• Anode Replacement: Loosen, lift, lower and tighten the spiral clamp, hoist away the spent anode, and install a new one.
• Slag Removal: Clear impurities like electrolyte slag and anode slag in the electrolytic cell to avoid affecting aluminum liquid purity and preventing blockages of internal pipelines and electrodes.
• Aluminum Tapping: Extract molten aluminum from the electrolytic cell, complete the whole process of hoisting, metering and transfer, and supply raw materials for subsequent molten aluminum processing.
• Anode Busbar Lifting: Precisely adjust the busbar height to maintain optimal electrolysis efficiency.
• Maintenance: Provide hoisting support for electrolytic cell installation, daily maintenance and fault repair, covering the disassembly, assembly and transfer of the cell’s upper/lower structures and scattered components.
