The invention discloses an extraction device for separating
rare earth elements. The extraction device includes a motor, a mixing and conveying
pipe, a mixing and conveying shaft, a liquid inlet pipeI, a valve I, a liquid inlet
pipe II, a valve II and the like; the motor is fixed to the left end of the mixing and conveying
pipe, an output shaft of the motor stretches into the mixing and conveyingpipe and is connected with the mixing and conveying shaft,
helical mixing blades are arranged on the mixing and conveying shaft, the left side of the mixing and conveying pipe is connected with the liquid inlet pipe I and the liquid inlet pipe II separately, the valve I is arranged on the liquid inlet pipe I, and the valve II is arranged on the liquid inlet pipe II. The extraction device for separating the
rare earth elements is simple in structure, high in practicability and low in operation cost; when
rare earth ions are separated through the extraction device, extraction time can be accurately controlled on the basis of fully ensuring that two phases are mixed uniformly, therefore, the extraction efficiency and the separation efficiency are improved to the maximum degree, and then different
rare earth ions are efficiently separated.
