Abstract

The invention relates to a lossless automated carbon change system and a control method. The carbon change system includes a carbon change vehicle, pressurized equipment, a sealed tank, a filter screen, a magnetic drive pump, a transit pool, an adsorption column, and input and output ports of the components, transmission pipelines and corresponding control valves. By means of a unique pipeline control mode, sealed carbon change operation is carried out under a pressure of 0.25-0.4MPa and the effect of water. The sealed tank can bear a maximum pressure of 1.0MPa, and during carbon adding, the sealed tank and the horizontal plane are in an angle of 10 degrees. Compared with the previous processes, the system and the method provided by the invention have the advantages of low labor intensity, fast speed, little human input, no potential safety hazard and the like, guarantee zero loss of the carbon change process, realize automated mine production, and also have a significant effect on concentrated recycling treatment of carbon foam.

Description

technical field [0001] The invention relates to the technical field of gold beneficiation, in particular to a non-loss automatic carbon replacement system and a control method with a high degree of automation. Background technique [0002] Among the existing gold extraction processes, the most widely used is cyanidation leaching, which uses activated carbon to dynamically absorb the gold in the leach solution, and then sends it to the desorption smelting workshop for purification. Affected by the adsorption capacity of activated carbon, when the concentration of precious liquid reaches a certain level, the activated carbon tends to be saturated with the passage of adsorption time, and the gold-loaded carbon in the adsorption column must be extracted in time. At present, in the actual production process, most gold mining enterprises still use manual carbon replacement to unload and add carbon. The process is slow and labor-intensive, and the loss of gold-loaded carbon is pron...

AI Technical Summary

Problems solved by technology

At present, in the actual production process, most gold mining enterprises still use manual carbon replacement to unload and add carbon. The process is slow and labor-intensive, and gold-loaded carbon is prone to loss during the operation process.

If you try to reduce the diameter of the carbon outlet through valve control, although you can reduce the possibility of carbon splashing during the carbon discharge process, the time for carbon discharge will be greatly increased, which will seriously affect the work efficiency.

At the same time, the leachate in the adsorption column flows away with the opening of the valve. Although it can be drained to the precious liquid pool for re-adsorption, it increases the burden of adsorption. Moreover, after the water in the adsorption column dries up, it also affects the sliding of the gold-loaded carbon. All the carbon in the column often has to be hit by various instruments, which will eventually affect the smooth structure of the inner wall. It is even more unfavorable for the free sliding of the gold-loaded carbon when unloading the carbon next time. In this case, the carbon content of each column Charging time will be more than 3 hours

Due to the manual carbon change, the operator will be indirectly or directly exposed to highly toxic cyanide during the carbon change process, which poses a fatal safety hazard and does not comply with safety and environmental protection regulations

[0003] To sum up, the design of artificial carbon replacement method is lacking, unscientific and unreasonable, and it is easy to cause the loss of gold, increase the labor intensity and work cost of workers, and have potential safety hazards
