AI Technical Summary

Problems solved by technology

Since the detection electrode is easily blocked and polluted by the industrial flotation slurry flow, due to the limitation of the application range of the single indicator electrode structure, and due to factors such as the incompatibility of the configured cleaning mechanism, the same This type of device cannot obtain interrelated, stable and consistent, real-time, online special-shaped multi-electrode potential parameters in the industrial flotation slurry flow

[0003] Since the potential at any point in the same electric field is unique, according to the experimental theory that the ions in the same thermodynamic system are often interrelated in physical and chemical changes, the current electrode seat detection mechanism and single indicator electrode device cannot be used online, Synchronous and multi-electrode potential detection can only be configured in a decentralized and multi-point manner, resulting in poor synchronization and poor correlation and order among the detection parameters; at the same time, the collective configuration has complicated structures and operations, and the correlation between the detection parameters is difficult. Sequential lack of long-term stability and consistency

Moreover, the high flow rate brings safety and balance difficulties to the detection electrodes, and the recovery process of the electrodes is more difficult to adapt to the heterogeneous multi-electrode structure.

Rigid structure of electrodes to clean The device has poor online detection adaptability due to the long time of detection electrode balance

Unable to meet the needs of ore pulp and similar high-velocity, large-specific-gravity, multi-phase complex media, real-time, synchronous, uniform, and continuous online special-shaped multi-electrode potential detection, it is difficult to obtain interrelated, stable and consistent special-shaped multi-electrode potential parameters
