The invention discloses continuous decomposition equipment of rare earth concentrates. The equipment comprises a main body, a two-way propeller and a driving module, wherein a feed port, two liquid feeding ports and two tail gas outlets are formed in the top of the main body, two discharge ports are formed in the bottom of the main body, and an insulation cavity is formed in the side wall of the main body; the insulation cavity is provided with an insulation liquid inlet and an insulation liquid outlet; the two-way propeller is arranged in the main body, and extends in the length direction of the main body; the two-way propeller comprises a rotating shaft, a first spiral blade and a second spiral blade; the first spiral blade is arranged on a first shaft section of the rotating shaft; the second spiral blade is arranged on a second shaft section of the rotating shaft; the spiral direction of the first spiral blade is opposite to the spiral direction of the second spiral blade, so that the first spiral blade discharges materials towards a first end of the rotating shaft, and the second spiral blade discharges materials towards a second end of the rotating shaft; and the driving module is connected with the rotating shaft. The equipment can realize efficient and continuous decomposition of the rare earth concentrates, guarantees continuous production operation, and prominently improves the decomposition rate of the rate earth concentrates.
Description
technical field [0001] The invention relates to the technical field of metallurgy, in particular, the invention relates to continuous decomposition equipment for rare earth concentrates. Background technique [0002] Baotou mixed ore (a mixed ore of bastnaesite rare earth and monazite) and bastnaesite are important components of rare earth ores in my country. According to the characteristics of Baotou mixed ore, the current industrial method to deal with this kind of ore is mainly concentrated sulfuric acid roasting method. The process of this method is continuous and easy to control, and it is easy to produce on a large scale. However, due to the decomposition of the mixed ore at high temperature, the thorium in the ore enters the slag in the form of thorium pyrophosphate, resulting in waste of thorium resources and radioactive pollution; and fluorine and Sulfur waste gas recycling is difficult. According to the characteristics of bastnaesite, the current industrial acid ...
