An intelligent control system for rare earth extraction production process

Abstract

The invention provides an intelligent control system for the production process of rare earth extraction, and relates to the technical field of rare earth extraction. The system includes a parameter management module that fills in the distribution ratio of each rare earth component in the feed liquid according to the composition of the rare earth raw material, monitors the flow parameters of the rare earth extraction site in real time, and changes the concentration of the feed liquid, the degree of saponification and the concentration of washing acid accordingly; through The main control module that controls the number of operations of the system by row ratio; corrects the separation coefficient, and reads and monitors the three flow parameters in the production process of rare earth extraction in real time; when the deviation between the tank distribution data and the standard flow data exceeds the set threshold, it will automatically Intelligent control module to adjust flow parameters to standard flow; production data management module to store calculated tank distribution data according to the regularity of system running time, and retrieve extraction tank distribution data or historical tank distribution curve; display production data A data display module for extracting tank distribution data or historical tank distribution curves retrieved by the management module.

Description

technical field [0001] The invention relates to the technical field of rare earth extraction, in particular to an intelligent control system for the production process of rare earth extraction. Background technique [0002] Rare earth refers to 15 lanthanide elements with atomic numbers from 57 to 71 in the periodic table of elements and 17 elements including scandium and yttrium that are chemically similar to lanthanide elements. Rare earth elements have excellent physical and chemical properties, so they are widely used in various fields, such as rare earth hydrogen storage alloys, luminescent materials, permanent magnet materials and other fields play an important role. [0003] There are many separation methods for separating single or multiple rare earth elements in rare earth mixtures, including fractional crystallization, fractional precipitation, ion exchange chromatography, solvent extraction, chemical vapor transport, redox and extraction resins Chromatography, et...
