In the process of aluminum electrolysis production, anode rod is the connecting conductor between anode carbon block and large busbar of the electrolysis cell, and its crimped conductivity will directly affect the energy consumption of electrolysis production and the safe and stable operation of the electrolysis cell. The surface of the anode rod is easy to be dirty, which will increase the contact voltage drop between anode rod and large busbar (increase in the contact resistance). When used, it will not only consume a lot of electric power, but also cause the contact surface to heat up due to the increase in resistance, which will bring potential safety hazards. Therefore, reducing the contact voltage drop between anode rod and large busbar has always been a key issue in the electrolytic production. And most of the enterprises in China use manual mechanical grinding to clean the surface of the aluminum guide rod, which has high artificial cost and inconvenient operation, and the mechanical grinding is abrasive for the substrate of the aluminum guide rod, so the actual effect is not ideal.

Zhengzhou Jingwei Technology Co.,Ltd has done a lot of analysis and research on the working conditions of various anode rods, and independently developed and produced a set of on-line automatic cleaning system for anode rods to realize the cleaning of the surface of aluminum guide rods. The whole set of production line has high degree of automation, convenient operation, short time, low cost and good effect. And it is equipped with corresponding hardware and software to realize the automation, informatization and intelligence of the system. Utilizing the existing conditions of the workshop and the catenary suspension system , the online automatic cleaning of the guide rods is realized.

• Green cleaning: Laser cleaning is used without any chemicals, and the waste after cleaning is solid and harmless powder;
• Non-damage cleaning: Non-contact cleaning. Compared to traditional mechanical grinding cleaning, laser cleaning does not generate mechanical force on the guide rod and cause guide rod wear;
• Low-cost cleaning: It can be used stably for a long time. And it has low operating cost, easy maintenance, and fast return on investment;
• Automatic cleaning: The equipment can realize fully automatic, unmanned operation;
• High cleaning efficiency: The equipment can be adapted to the operating requirements of the catenary suspension system. And the efficiency of the supplied equipment can reach 90 groups/hour.

The equipment can automatically complete all actions without human intervention. It also does not affect the existing production rhythm or increase the workload of personnel;

The device can detect the position of the cleaning head in real time. When the cleaning head is not in the safe position, the guide bar group on the catenary suspension system is not allowed to pass, which is high safety.

The equipment can adapt to various application conditions of the catenary suspension system. When power failure, gas shutdown, and guide rod in place are not stopped, the equipment can realize interlocking to ensure safety;

The equipment comes with dust collection facilities to avoid the spread of dust;

The equipment can be used to clean the guide rod surface of different specifications.
