Device for purifying rare earth oxide from old rare earth materials and application method of device

Abstract

The invention discloses a device for purifying rare earth oxide from old rare earth materials. A purification box is included and internally provided with a purification plate. Lifting columns are arranged on the two sides of the purification plate. An elevating device is arranged at the upper ends of the lifting columns and comprises a left elevating rod and a right elevating rod. One end of theleft elevating rod is connected to the left lifting column, and one end of the right elevating rod is connected to the right lifting column. The elevating device is fixedly connected to a fixing frame. A scraping device is arranged at the upper end of the left side of the purification box. According to the provided device for purifying rare earth oxide from old rare earth materials, the device canrapidly purify rare earth oxide from old rare earth, meanwhile, a transmission device is used for conducting segmented drying recycling on rare earth, the efficiency of the rare earth recycling process is improved, meanwhile, the purification process is further simplified, the recycling efficiency is improved, the rare earth waste stacking problem is solved, and pollution to the environment is reduced.

Description

technical field [0001] The invention relates to the technical field of rare earth recovery, in particular to a device for purifying rare earth oxides from old rare earth materials and a method for using the same. Background technique [0002] Rare earth has now become an extremely important strategic resource. Rare earth element oxides refer to oxides of 15 lanthanide elements with atomic numbers from 57 to 71 in the periodic table of elements, and oxides of scandium and yttrium, a total of 17 elements whose chemical properties are similar to lanthanide elements. Rare earth elements have been widely used in petroleum, chemical industry, metallurgy, textile, ceramics, glass, permanent magnet materials and other fields. With the advancement of science and technology and continuous breakthroughs in application technology, the value of rare earth oxides will increase. [0003] In recent years, due to the excessive exploitation of rare earth resources, not only caused a great wa...

AI Technical Summary

Problems solved by technology

[0003] In recent years, due to the excessive exploitation of rare earth resources, it not only caused a great waste of resources, but also caused serious pollution to the environment.

Therefore, increasing the recycling of rare earth materials has greater social, environmental and economic benefits. In the rare earth recycling process, multi-process operations are generally adopted. During the operation, the wet-purified sediment needs to be taken out of the reaction tank and then transferred. To carry out the corresponding operation in another operation process is time-consuming and laborious, which reduces the efficiency during operation and cannot be continuously purified, so that the recycling efficiency of rare earth waste is greatly reduced, resulting in a larger accumulation of rare earth waste in the environment. Environmental hazards are becoming increasingly prominent
