Description

Technical Field

[0001] This utility model relates to the field of recycling equipment technology, and in particular to a multi-stage sedimentation recycling device for rare earth polishing powder waste. Background Technology

[0002] During use, polishing powder can become ineffective due to the diffusion of glass powder particles onto the surface of rare earth oxides, the continuous mixing of oil and large foreign particles, which reduces the content of effective components in the polishing powder and hinders the contact between the glass surface and the polishing powder particles. This results in the polishing powder becoming ineffective and generating waste. In the early days, the treatment of rare earth polishing powder waste was relatively simple, often involving landfill disposal. However, this method not only occupies a large amount of land resources but may also cause environmental pollution. People have gradually realized the importance of recycling waste rare earth polishing powder and have begun to study methods for recovering valuable components such as rare earth elements from waste, as well as technologies for applying waste to other fields. Recycling equipment technology is one such application.

[0003] In the early stages of recycling technology development, the recycling and processing methods for rare earth polishing powder waste were relatively primitive and simple. Initial separation was achieved through manual collection and screening, selecting out larger, directly usable portions. However, there was a lack of effective treatment methods for the remaining waste, which was often simply piled up or landfilled. This method was not only inefficient but also put significant pressure on the environment, as the rare earth and other heavy metal elements contained in the waste could seep into the soil and groundwater, causing environmental pollution. In recent years, with the continuous development of science and technology, various new recycling technologies have emerged, including multi-stage sedimentation recycling technology. By setting up multiple sedimentation zones in the sedimentation tank, the waste undergoes multiple sedimentation processes in different areas, improving the purity and efficiency of recycling.
