Mine slurry grade on-line detection method

Abstract

The invention provides a pulp grade online detecting device and detecting method, comprising a pulp container with a feed port and a discharge port, wherein a inductance coil is set on the discharge tube of the discharge port of the container. A simple inductance coil is set on the tube for conveying the pulp, therefore the frequency of the energizing voltage of the inductance coil is adjusted tobe consistent with the inherent resonance frequency and the content of the metal in pulp, namely pulp grade, is obtained by measuring the induction current generated when the metal in pulp passes through the inductance coil. The invention has features: high accuracy of measurement, stability, reliability, simple structure, high work efficiency, low labor intensity, wide scope of application. The pulp grade during online flowing can be accurately measured to ensure the product quality, reduce the cost, increase the work efficiency, provide a measuring device with high guarantee for the full automatic control and provide accurate reference for investment and decision.

Description

technical field [0001] The invention relates to a detection device and a detection method, in particular to a device and a method for detecting the grade of ore pulp. Background technique [0002] The pulp grade can not only verify the quality of the pulp, but also an important indicator that directly reflects whether the mineral has mining value. At present, the grade of pulp is mostly detected by manual sampling, chemical analysis and other methods. Therefore, due to the influence and limitation of many human factors such as sampling points, it is difficult to accurately measure the actual grade of pulp. At the same time, this backward and extremely low-efficiency manual The operation is far from meeting the needs of modern production, and it may even cause major economic losses such as increased production costs and large discrepancies in sales prices due to grade differences. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies in t...
