A new heating device for rare earth production, which includes an alkaline hydrolysis tank body, a temperature control device, a pressure regulating device, a power supply and a temperature measuring element. A novel heating method for rare earth production, comprising the following steps: (1) equipment preparation and connection; (2) setting temperature control program for heating. The invention has the advantages of saving energy and reducing consumption, achieving comprehensive utilization of resources, good economic benefits, and good development and application prospects.

Description

technical field [0001] The invention relates to a novel alkaline hydrolysis tank, a novel heating device and a heating method, in particular to a novel alkali hydrolysis tank, a novel heating device and a heating method for rare earth production. Background technique [0002] Alkaline chlorination of rare earth concentrates requires high decomposition rate and yield, while the traditional eddy current electric heating alkaline hydrolysis tank generally directly raises the reaction temperature to 150 degrees, which is particularly easy to cause paste or overflow at high temperature, and the product It is easy to change the price, and the slurry will seriously corrode the alkaline hydrolysis tank after the pot is pasted or overflowed. In addition, the traditional alkaline hydrolysis tank generally uses a one-layer stirring paddle. As the reaction temperature rises and the water evaporates, the slurry becomes thicker and thicker, which is easy to cause a paste pot. Contents o...
