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.
The cleaning device with a rigid structure of the electrode has poor adaptability to online detection due to the long time to balance the detection electrode
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

Embodiment 1

[0044] Put a domestic pH302-2 spherical glass pH electrode and a silver / silver chloride electrode into the electrode holder respectively, and then position the sensitive surface of the electrode close to the vertical scraper. At this point, put the main unit in the pulp to be measured, and then connect the electrode guide wire to the meter to realize the online electrode potential detection under the recovery state of the electrode.

Embodiment 2

[0046] Put a domestic pH302-2 spherical glass pH electrode, a silver / sulfur ion selective electrode, a flat platinum electrode, and a silver / silver chloride electrode into the electrode holder, and the sensitive surface of the electrode is tightly connected to the notch of the scraper. Stick the positioning, put the host in the pulp to be tested. Finally, the electrode guide wire is connected with the instrument, that is, the synchronous and real-time detection of the online multi-electrode potential under the electrode recovery operation state is realized.

Description

technical field [0001] The multi-potential detection device for ore pulp relates to a device for realizing real-time, synchronous and on-line continuous detection of special-shaped multi-electrode potentials, which is suitable for use in aqueous solution as well as in ore pulp and similar multi-phase, high-specific-gravity, and high-flow-velocity media. Background technique [0002] In China, there has been no report of a multi-electrode potential on-line detection device applied to industrial flotation pulp flow. In foreign products, there are only single indicating electrode devices for detecting pH or ORP. 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, o...
