Mixing and stirring system based on lanthanum-cerium rare earth processing and production

Abstract

The invention relates to a mixing and stirring system based on lanthanum-cerium rare earth processing production. The mixing and stirring system is characterized in that a filter screen is arranged in a stirring tank to layer the stirring tank, and large rare earth mineral particles are intercepted and stirred in the upper stirring layer; the small particles are stirred in the lower stirring layer, a rare earth mixture stirring quality evaluation parameter K is calculated in the stirring process, the stirring effect is monitored, the stirring effect of each stirring layer is judged, and a central control processor controls the stirring speed of stirring rods of each stirring layer and the filtering speed of the filter screen in the stirring process; and different stirring layers use different stirring parameters, the upper stirring layer and the lower stirring layer conduct stirring at the same time, and by controlling the stirring speed and the vibration speed of the filter screen, the falling speed of the rare earth mixture, and flowing of the mixture in the stirring layers, the stirring speed and the stirring effect are improved.

Description

technical field [0001] The invention belongs to the field of stirring and mixing, in particular to a mixing and stirring system based on the processing and production of lanthanum cerium rare earth. Background technique [0002] China is truly one of the countries with the largest rare earth resources in the world. The proven rare earth resources are about 65.88 million tons; China is not only rich in rare earth resources, but also has a complete range of minerals and rare earth elements, and a reasonable distribution of rare earth grades and ore points. Such advantages have laid a solid foundation for the development of China's rare earth industry, among which lanthanum and cerium rare earths are the most common. In the process of mixing the agent, the stirring speed and the stirring time all have an impact on the mixing process, but the following problems still exist in the prior art; [0003] 1. During the mixing and stirring process of rare earth mineral particles, due ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that part of the rare earth agglomerate will sink to the bottom during the rare earth stirring process, and the lack of stirring of this part of the sinking rare earth will cause the problem of uneven stirring of the rare earth and the lack of acquisition means for the rare earth stirring situation during the rare earth stirring process. For this reason the present invention provides a kind of mixing system based on the processing and production of lanthanum cerium rare earth, which comprises:
