Rare earth production process material information collection and analysis intelligent control system

Abstract

The invention discloses an intelligent control system for collecting and analyzing material information in the rare earth production process. The monitoring instrument; the main control room of the instrument is equipped with a DCS control system; the monitoring instrument includes an electromagnetic flowmeter, an electric valve, a solenoid valve, a liquid level gauge, a liquid level switch, a rotameter and an I / O control cabinet ; The DCS control system automatically controls the monitoring instruments on the production line of each process, regulates and monitors the process and equipment flow, and collects material information to achieve feed ratio control and meet the requirements of automatic regulation. The putting into use of the present invention not only greatly saves the workload of manual operation, but also transforms the traditional extensive production operation control into intelligent precise control.

Description

technical field

[0001] The invention belongs to the field of intelligent control equipment, and in particular relates to an intelligent control system for collecting and analyzing material information in the rare earth production process used in the rare earth smelting and separation process. Background technique

[0002] The rare earth market is a diversified market. It is not just a product, but 15 rare earth elements and yttrium, scandium and their various compounds ranging from chlorides with a purity of 46% to single rare earth oxides and rare earth metals with a purity of 99.9999%. Has a variety of uses. There are currently two rare earth smelting methods, namely hydrometallurgy and pyrometallurgy. However, no matter what kind of smelting method is used, its automatic and intelligent production level is low, and it needs to consume more manpower and material resources. Contents of the invention

[0003] The purpose of the present invention is to provide an intellig...
