Abstract

This invention discloses a rare earth series extraction intelligent control system, which comprises operation station and spot executive system and is characterized by the following: fixing model station, together with operation, connected to the OPC communication module, wherein, the above two and the PLC controller are connected to the spot executive system through industry Ethernet and Profibus-DP. The invention also provides one method to execute the control system, which is characterized by the following: the model station feedbacks the difference value between the optimization parameter by experiences with spot parameters as the basis of the operation station. The invention also discloses one multi-media monitoring system to real time display the spot situations in workshops.

Description

technical field [0001] The invention belongs to the technical field of extraction of rare earth metals, especially rare earth extraction by using an organic compound solution. Specifically, the invention provides an intelligent control system for rare earth cascade extraction and separation. Background technique [0002] The rare earth metal group includes 17 elements, their chemical properties are very similar, and they always exist in the form of symbiotic minerals in nature, so it is extremely difficult to separate and purify them. Since the 1970s, the technology of separating rare earth metals by means of cascade extraction has been invented, that is to use the slight difference in properties between rare earth metal elements to perform repeated extractions to obtain pure products. The process flow of the rare earth cascade extraction and separation process is as follows: figure 1 As shown, the entire extraction production line is composed of multi-stage extraction tank...
