Abstract

The invention discloses an online titration measuring device for the pH value of ore pulp, which comprises a pulp sampling and processing device, a pulp secondary filtering device and an automatic titration device. The pulp sampling and processing device further includes a pulp lifting device, a pulp primary processing device, an Mine valve, sampling bypass valve and sampling valve; the secondary filtration device of the ore pulp adopts the gravity filtration method of the filter element to process the transported ore slurry solution, and further includes a solution buffer tank, a bypass valve, a filter tank, a filter element, a liquid level switch, Empty valve; the automatic titration device utilizes photometric titration to realize automatic titration measurement, and further includes a multi-channel switching device, a sampling pump, a miniature electromagnetic valve group, a first peristaltic pump, a syringe pump and a photometric device, and the above-mentioned device realizes the pH value of the pulp The online high-precision measurement of the value solves the problems of measurement accuracy and stability of the electrode method.

Description

technical field [0001] The invention relates to the technical field of measuring instruments, in particular to an online titration measuring device for the pH value of ore pulp. Background technique [0002] At present, in the mineral processing process, especially in the mineral processing industry, the pH value of the ore pulp is an important factor affecting the mineral processing index, but the online measurement of the pulp pH value has not been fundamentally resolved, resulting in no domestic processing plant that truly realizes the automatic pH value. control. [0003] Measuring the pH value by the electrode method is the most commonly used online measurement method in the current mineral processing production, but it cannot realize the continuous high-precision measurement and automatic control of the pH value of the pulp, and there are two problems: 1) The accuracy is unstable. Calcium and scaling are easy to accumulate in the slurry, which affects the ion exchange...
