Description

technical field [0001] The invention relates to an integrated detection device for detecting the viscosity and density of a dense medium suspension, belonging to the technical field of detection. Background technique [0002] Dense medium suspension is a mixed liquid composed of coal slime, iron powder and water, which is used as the separation medium in the dense medium beneficiation process. The viscosity and density index of dense medium suspension directly affect the product quality of dense medium beneficiation, and are important technical parameters of dense medium beneficiation process. [0003] For the viscosity detection of dense medium suspensions, indirect measurement methods are commonly used at home and abroad, that is, firstly, the content of magnet powder in the suspension is detected according to the principle of electromagnetic induction, and at the same time, the density of the suspension is detected by an isotope density meter, and the suspension is conver...

AI Technical Summary

Problems solved by technology

Due to the differences in particle size, surface shape, and hydrophilic properties of coal slime, there are deviations in the viscosity of dense medium suspensions represented by the content of coal slime; coupled with the intermediate errors brought about by empirical formulas, it is difficult to ensure the accuracy of measurement

[0004] For dense medium suspension density detection, the current common method is to use radioactive isotope (Cs137) irradiation detection method. Although this sensor can basically meet the process requirements, due to its large calibration error, it is also difficult to manage and maintain during use. Security risks

At the same time, with the enhancement of our country's awareness of environmental protection, the approval and management of the use of radioactive instruments have become more and more stringent. Many companies have delayed their projects due to their inability to obtain environmental protection approval procedures.
