Description

Technical Field

[0001] The utility model relates to a praseodymium-neodymium oxide production cooling device, belonging to the technical field of praseodymium-neodymium oxide production. Background Art

[0002] Praseodymium-neodymium is an element with relatively large output and high application value among rare earth elements. It plays an important role in the rare earth field and often influences the direction of the rare earth market. The main use of praseodymium-neodymium metal is to produce rare earth permanent magnet materials. The characteristics of rare earth permanent magnet materials are high saturation magnetization intensity of various phase anisotropies of magnetic crystals, high residual magnetic induction intensity, high coercive force and high maximum magnetic energy level. It is mainly used in micromotors, energy-saving motors, speakers, medical magnetic resonance imaging devices, etc. Praseodymium-neodymium metal can be prepared by praseodymium-neodymium chloride, praseodymium-neodymium oxide molten salt electrolysis or metal thermal reduction method. The praseodymium-neodymium oxide molten salt electrolysis method is generally used in production. The praseodymium-neodymium oxide for electrolysis requires uniform particle size, high activity and excellent melting performance in electrolyte. In actual production, praseodymium-neodymium oxide is obtained by burning praseodymium-neodymium carbonate or praseodymium-neodymium oxalate. Burning can be divided into dynamic burning and static burning. Static burning adopts muffle furnace, inverted smoke kiln and other methods, which has the advantages of simple equipment and less investment, but also has the disadvantages of high energy consumption, small output, easy contamination of products by utensils, difficult to control product quality, and unsuitable for large-scale production. It has been gradually eliminated by praseodymium-neodymium oxide manufacturers. Dynamic burning is generally divided into two forms: tunnel kiln and rotary kiln. Tunnel kiln can produce continuously and has a large production volume, but it has the disadvantages of high labor intensity of workers, easy contamination of materials by utensils, uneven temperature in the kiln body causing overburning of some materials, etc. Rotary kiln production can be mass-produced and reduce the labor intensity of workers.

[0003] In order to improve working efficiency, most of the existing calcination rotary kilns are connected by multiple calcination rotary kiln rollers. However, the temperature in the calcination rotary kiln is relatively high during operation, and the kiln body is twisted at the connection points of the multiple calcination rotary kiln rollers due to the excessively high temperature, and the kiln cannot operate, thereby reducing the production efficiency of praseodymium neodymium oxide.
