Device for preparing rare earth nano-oxide and method of using the same

Abstract

The invention provides a rare earth nanometer oxide preparation device and a use method thereof, belonging to the technical field of rare earth material preparation. It solves the problem that the product obtained by the existing precipitation method is prone to agglomeration, and the product after agglomeration is often blocked during filtration due to its large volume, resulting in difficult filtration. the material precipitation rate. The rare earth nano-oxide preparation device and the method for using the same include a heating box, four bases are arranged at the lower end of the heating box, two heating chambers are arranged in the lower end wall of the heating box, and a heating mechanism is arranged in the heating box , the heating mechanism is provided with a flow guiding mechanism. The rare earth nano-oxide preparation device and the using method thereof avoid the agglomeration of the material after precipitation and molding on the one hand, and on the other hand, the original solution can be recycled to improve the material precipitation rate in the original solution.

Description

technical field [0001] The invention belongs to the technical field of rare earth material preparation, and relates to a rare earth nanometer oxide preparation device and a use method thereof. Background technique [0002] Rare earth elements, also known as rare earth metals, are widely used in electronics, petrochemical, metallurgy, agriculture and other fields, and are also important strategic resources in my country. The precipitation method is widely used because of the nucleation of the solution, easy control, and high sample purity. [0003] However, the products obtained by the precipitation method are prone to agglomeration. Due to the large volume of the products after agglomeration, the products are often blocked during filtration, resulting in the problem of difficult filtration. Moreover, the original solution after filtration and the original liquid vapor generated during the heating process are not very good. On the one hand, it causes waste of the original sol...

AI Technical Summary

Problems solved by technology

[0003] However, the product produced by the precipitation method is prone to agglomeration. Due to the large volume of the agglomerated product, it is often clogged during filtration, resulting in the problem of difficult filtration, and the original solution after filtration and the original solution steam generated during the heating process are not well processed. On the one hand, it causes the waste of the original solution, and on the other hand, it reduces the material precipitation rate in the original solution.
