Specific implementation mode
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
As shown in Figure 1, a kind of Extraction of rare eart wastewater treatment equipment, including evaporator 1, flash column 2, jet pump 3, cooling
Crystallizer 4, centrifuge 5, feeding pipe 6, slurry delivery tube 7；
The evaporator 1, the flash column 2, the cooler crystallizer 4, the centrifuge 5 pass sequentially through pipe from left to right
Road connects；The evaporator 1 is open-top receptacle, and 1 right side of the evaporator is provided with feeding mouth 11, and the feeding pipe 6 is set vertically
It sets between the flash column 2 and the cooler crystallizer 4, the feeding pipe 6 bends in 90 ° in bottom end and crosses over the flash distillation
Tower 2 is then connected to the feeding mouth 11；Connect by the slurry delivery tube 7 between the flash column 2 and the cooler crystallizer 4
It connects, it is in the horizontally disposed feeding pipe 6 that 7 front half section spiral windings of the slurry delivery tube, which are lived after bending,；
The jet pump 3 is arranged in the open top of the evaporator 1, the air entry of the jet pump 3 and the sudden strain of a muscle
