A mixing and stirring system based on the processing and production of lanthanum and cerium rare earths

Abstract

The invention relates to a mixing and stirring system based on the processing and production of lanthanum-cerium rare earths, which includes: the invention sets a filter screen in the stirring tank to layer the stirring tank, and larger particles of rare earth mineral particles are intercepted and stirred in the upper stirring layer , Smaller particles are stirred in the lower stirring layer. During the stirring process, the rare earth mixture stirring quality evaluation parameter K is calculated to monitor the stirring effect and determine the stirring effect of each stirring layer. The central control processor controls the stirring rods of each stirring layer during stirring. Stirring rate and filtering speed of the filter screen, different stirring layers use different stirring parameters, the upper stirring layer and the lower stirring layer are stirred at the same time, by controlling the stirring rate and the vibration rate of the filter screen, the falling rate of the rare earth mixture is controlled, and the mixture is stirred. Layer flow, improve stirring speed and stirring effect.

Description

technical field [0001] The invention belongs to the field of stirring and mixing, and specifically relates to a mixing and stirring system based on the processing and production of lanthanum and cerium rare earths. 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's rare earth resources are not only rich in reserves, but also have complete mineral types and rare earth elements, rare earth grades and reasonable distribution of ore points. and other advantages have laid a solid foundation for the development of China's rare earth industry, among which lanthanum cerium rare earth is the most common. In the process of mixing the agent, the stirring speed and the stirring time all have an influence on the mixing process, but the following problems also exist in the prior art; [0003] 1. During the mixing and stirring process of rare earth miner...

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:
