Device for continuously decomposing rare earth concentrate ore

A device for continuously decomposing a rare earth concentrate ore, comprising:

• a body having a material inlet, two liquid inlets and two exhaust gas outlets disposed at the top of the body, two material outlets disposed at the bottom of the body and a heat preservation chamber provided inside a side wall of the body, wherein:
• the material inlet is located in the middle of the top of the body, and is configured to receive the rare earth concentrate ore,
• one of the two liquid inlets is located at a first side of the material inlet and the other one of the two liquid inlets is located at a second side of the material inlet,
• one of the two exhaust gas outlets is located at the first side of the material inlet and the other one of the two exhaust gas outlets is located at the second side of the material inlet,
• one of the two material outlets is adjacent to a first end of the body and the other one of the two material outlets is adjacent to a second end of the body, each of the two material outlets is configured to discharge a decomposed ore, and
• the heat preservation chamber has a heat preservation liquid inlet and a heat preservation liquid outlet;
• a bidirectional propeller provided in the body and extending along a length direction of the body, comprising:
• a rotating shaft comprising a first shaft section and a second shaft section,
• a first spiral blade disposed on the first shaft section of the rotating shaft, and
• a second spiral blade disposed on the second shaft section of the rotating shaft, wherein a spiral direction of the first spiral blade is opposite to that of the second spiral blade, such that the first spiral blade discharges materials toward a first end of the rotating shaft and the second spiral blade discharges materials toward a second end of the rotating shaft;
• and
• a driving assembly connected to the rotating shaft.
