Description

Technical Field

[0001] The present invention relates to the technical field of rare earth waste recycling, and in particular to a rare earth waste recycling process monitoring system and method based on industrial data processing. Background Art

[0002] Rare earth waste mainly comes from scraps and obsolete components from the production of magnetic materials. Its composition is complex and contains a variety of valuable elements such as neodymium, iron, and boron. Traditional recycling methods have problems such as low efficiency and high pollution, making it difficult to meet large-scale demand. Magnetic separation is a key separation method in the recycling of rare earth waste. It mainly relies on the differences in magnetic characteristics of different components in the rare earth waste to achieve separation. Rare earth waste generally comes from the production process of magnetic materials. For example, scraps generated during the manufacturing process of neodymium iron boron permanent magnets. This type of rare earth waste contains a variety of valuable elements such as neodymium, iron, and boron, and has a complex composition. Therefore, magnetic separation technology is used to apply a magnetic field so that the rare earth element particles with strong magnetism can be adsorbed or deflected by the magnetic force, while non-magnetic or weakly magnetic impurities are separated from the sorting area due to gravity or centrifugal force, thereby achieving effective recovery of rare earth elements.

[0003] However, existing technologies rely solely on static indicators, such as the recovery rate or single component analysis of rare earth waste, to assess recycling quality. Consequently, they neglect the dynamic tracking of the magnetic separation process during rare earth waste recycling. Furthermore, existing technologies fail to consider the coupling between the operating status of the recycling equipment and the magnetic separation state of the rare earth waste. This results in the rare earth waste recycling process being in a state of "extensive control" for a long time, making it impossible to adjust the recycling equipment parameters in a coordinated manner. This leads to fluctuations in the efficiency of the magnetic separation process, making it difficult to achieve a dual improvement in both treatment efficiency and quality.

[0004] In order to solve these problems, the present application designs a rare earth waste recycling process monitoring system and method based on industrial data processing. Summary of the Invention

[0088] In this embodiment, if Figure 4 As shown, in step S3, the equipment processing status of the recycling equipment in the rare earth waste magnetic separation process is analyzed, which specifically includes the following steps:

[0089] S31, extracting equipment status data of the recycling equipment;
