 The Status of Anode Jacking Frame industry
 
The anode busbar lifting frame (hereinafter referred to as the lifting frame) is used as the key equipment for the production of electrolytic aluminum. The basic operation process is to lift the lifting frame on the electrolytic cell by electrolytic multi-purpose driving, and aim at the anode Rod, the operation of the lifting frame on the number of anodic clamping force to hold the corresponding anode guide and apply force to close to the anode bus, a number of operators with a wrench (or operation to enhance the frame on the sliding frame of the air motor) Open a number of small box fixture, and then upgrade the anode bus to the highest position, and then tighten a number of small box fixture, loosen the lifting frame on the anode fixture, by the multi-purpose traffic lift frame will be lifted to the next station for the same operation.
 
At present the industry has a considerable number of the use of the anode bus to enhance the framework of lifting the bus operation using ventilation holding mechanism to hold the aluminum rod on the busbar, requiring compressed air pressure of not less than 0.6MPa, this workshop must be suspended from the aluminum Other use of compressed air operations, to ensure that the normal operation of the bus. During the operation, if the compressor air pressure drops, the top membrane cylinder is disconnected, the anode guide rod will be separated from the balanced bus, and the circuit will be disconnected due to the failure of the air compressor, the shutdown, the air supply pipe loss, the breakage, etc. Guide rod and balance the big bus to ignite, a serious short-circuit explosion, leading to a series of power outages, resulting in casualties, equipment damage and other major accidents. This kind of lifting frame has the design defect, needs to be reformed or renewed.


 In addition, the current industry in the use of the anode bus to enhance the framework is only played a role in the transfer frame, and lift the bus operation of the key process - small box clamp release and tightening only by the lifting frame other than the following two Way to complete:
 
① manual operation of the wrench to complete the small box of the release and tightening of the fixture, usually 8 to 9 people standing on the high temperature of the slot plate to complete the labor costs, workers labor intensity, low efficiency, and small box The tightening of the degree of inconsistency, tightening torque can not meet the requirements, aluminum rod and bus contact pressure drop is inconsistent and too large. The average time to manually release a small box of fixtures is close to 10 seconds.
 
② four operators were operating on the anode busbar frame on both sides of the sliding frame on a pneumatic motor drive wrench to release and tighten the small box fixture one by one, although the operator reduced the labor intensity, but the higher pressure requirements (Not less than 0.62MPa), the air consumption is large (2.69m3 / m), the sliding mechanism is cumbersome, slow to run, the wrench is difficult to accurately insert the small box fixture, the production efficiency is low, according to the measured, a skilled operator Loosen the side of the 12 small box fixture, with a time close to 100s.

 In the process of lifting the bus, with the above two ways to release and tighten the small box of fixtures, due to the reasons for the operator or the reasons for air pressure fluctuations, may cause the small box card is not in place or tightening torque shortage, Resulting in the phenomenon of extreme pole or local anode slippage, resulting in lifting frame strain and groove voltage fluctuations, triggering anodic effect, which damage the equipment, hurt the body, encountered rainy weather, due to reduced air quality, this phenomenon is more serious.
 
Small box clamp tightening force is not enough, the busbar voltage drop can be as high as 15mV or more, resulting in black voltage rise, increase power consumption. And each small box of the degree of tightening of the fixture will lead to uneven distribution of anode current, affecting the current efficiency of the electrolytic cell.



Anode busbar lifting frame in the domestic electrolytic aluminum industry has been nearly three decades of history, but the equipment behind the technology, technology updates slowly, has lagged far behind the rapid development of China's electrolytic aluminum industry, the development and application of a new generation of anode bus The framework has become a top priority.



 The Innovative technology solutions of "Joda" brand automatic anode jacking frame
 
As a new generation of bus to enhance the framework, "Jiuda" brand automatic anode bus lifting frame completely overcome the existing frame to enhance the various defects to a new user-friendly design concept, into the modern high-tech industrial design essence, making the product more reliable , Advanced, energy saving, functional, easy to use. The product is based on the following technical innovation concept, through the scientific and sophisticated design, long time multi-operation trip functional test and reliability test, the refinement of manufacturing, and now has been the perfect realization of industrial applications, will lead to create a new process of electrolytic aluminum Chapter.
 
1. In the anode jacking frame of each of the anode fixture to install a hydraulic torque wrench to complete the release of each small box of fixtures and tight, accurate, reliable, complete liberation of artificial. Compared with the pneumatic and electric, the hydraulic drive has the advantages of smooth rotation, large torque and low speed stability, and is not affected by the compressed air pressure and quality. It can guarantee the consistency of the tightening torque of each box, Can be easily adjusted according to the size of the tightening torque, with a greater torque to tighten the small box fixture, so that the guide rod and bus more closely contact, contact resistance deviation is small, lower guide rod voltage drop, so that the anode current distribution , Reduce the horizontal current of the electrolyzer, reduce the vertical magnetic field, so that the electrolytic cell running stable, improve current efficiency, with significant energy saving effect.
 
Fully automatic anode busbar lifting frame of the various hydraulic torque wrench at the same time operation, without moving, operating speed greatly improved, each operation can be reduced more than 15 minutes. According to the automatic anode busbar lifting frame measured data, the hydraulic torque wrench releases each box with 2s, while tightening the 16 small box jets with only 20s, the automatic anode busbar lifting frame can be significantly Improve production efficiency, reduce the interference of the bus operation to the electrolytic cell.
 
2. The use of large programmable logic controller (PLC) and solid state relay to achieve the anode busbar frame automatic control, functional, high reliability, anti-interference ability, fully adapt to the electrolytic workshop strong magnetic field environment.
 
3. Full remote control operation, remote control button interlock control, easy to operate, safe and reliable. The original need 11 people to complete the bus operation, only 4 to 5 people can easily complete.
 
4. Self-developed multi-function solenoid valve, pneumatic, electric one control, to adapt to the electrolytic workshop strong magnetic environment.
 
5. Equipped with full manual control system.
 
6. The gas-tightening mechanism is equipped with a large-capacity gas tank and a supercharging device is installed. When the compressed air pressure is as low as 0.4MPa, the busbar operation can be carried out and the stability of the electrolytic cell during the operation of the bus safety.



 The significant economic benefits of "Joda" brand automatic anode jacking frame
 
1. Significantly reduce labor costs
 
The original bus operation, which was completed by 11 operators, was completed from 4 to 5 people using a fully automatic anode busbar lift frame and the time was reduced from the original average of 13 minutes to 8 minutes, greatly improving labor productivity. For an annual output of 500,000 tons of electrolytic aluminum plant, assuming that the monthly wage of 5,000 yuan per year, the annual wage savings of about 600,000 yuan.
 
2. During the process of lifting the bus, the tank voltage is reduced and the energy saving effect is remarkable. A 240KA electrolyzer, with the existing anode bus to lift the frame to lift the bus during the operation of the tank voltage rose to 4.5V, and the use of automatic anode bus to enhance the frame when the tank voltage rose to only 4.0V, which each operation of a cell Can save 0.5X240X0.1 = 120kWh, 20 times per slot per year, the annual energy saving 2400 kWh.
 
3. As the voltage fluctuation becomes smaller during the operation of the busbar operation, the possibility of the anode effect of the electrolytic cell is greatly reduced, and there is no longer a phenomenon of ignition between the aluminum pole and the busbar, which avoids the guide rod and the busbar Contact surface damage, the process is no longer use the effect of rods, saving a lot of costs.
 
4. Automatic anode bus lifting frame using hydraulic torque wrench to tighten the small box fixture, tightening torque greater and more accurate, aluminum rod and bus contact more closely, contact resistance decreases, guide rod voltage drop significantly. At present the electrolytic aluminum industry pole rod voltage drop average of 13 ~ 15mV, for the management of the electrolytic cell can be as high as 20 ~ 50mv. Application of "Jiuda" brand automatic anode bus lifting frame for carrying bus operation, the field measurement pressure drop of 9.1 ~ 9.7mV, an average reduction of 5mV, each 240KA electrolyzer annual energy saving 240 × 5 × 24 × 365 = 10512kWh. For a production capacity of 800,000 tons of electrolytic aluminum enterprises, about 600 electrolyzers, electricity prices by 0.5 yuan / kWh calculation, the annual savings of electricity 10512 × 600 × 0.5 = 3153600 yuan. In fact, the domestic electrolytic aluminum industry is currently more than 300kA electrolytic cell slot type, energy-saving effect is much larger than this figure.
 
China's aluminum industry after years of rapid development, has now entered a serious excess capacity of the stage, a large number of electrolytic aluminum enterprises are facing a loss situation, the cost of efficiency as a matter of urgency, "long" brand automatic anode bus lift frame Will be electrolytic aluminum enterprises out of difficulties to help hand!
