AI Technical Summary

Technical Problem

The existing rare earth chloride extraction device has a single mixing and stirring direction of the stock solution and the extractant, and has poor adaptability, resulting in unsatisfactory mixing effect, affecting the extraction and separation effect, and also has poor filtration and removal effect of impurities.

Method used

A rare earth chloride extraction device is designed, including a first stirring mechanism and a linkage mechanism. The stock solution and the extractant are rapidly mixed and stirred through the first stirring mechanism, and the second stirring mechanism is driven to rotate and mix through the linkage mechanism to improve the stirring effect. In addition, the device is equipped with a filter mechanism and a scraping mechanism for removing impurities and keeping the filter assembly unobstructed.

Benefits of technology

Through multiple mixing and stirring, the extraction and separation effect is significantly improved, impurities can be effectively removed, a purer chloride rare earth solution can be obtained, and blocked of the filter assembly is avoided, which improves the overall performance of the device.

Abstract

The invention belongs to the technical field of chloride extraction, and in particular to a rare earth chloride extraction device, comprising a base, a support column and an extraction tank, wherein a first stirring mechanism is arranged on the extraction tank, a linkage mechanism is sleeved on the outer side of the first stirring mechanism, and a second stirring mechanism is equidistantly arranged on the linkage mechanism in the axial direction. While the first stirring mechanism is used to quickly mix and stir the rare earth chloride stock solution and the extractant in the extraction tank, the first stirring mechanism can be linked to drive the second stirring mechanism to revolve through the linkage mechanism while rotating to perform secondary mixing and stirring of the rare earth chloride stock solution and the extractant in the extraction tank, and the stirring and mixing effect is good, and the extraction and separation effect can be effectively improved. When the linkage drive module rotates, the scraping mechanism can be driven to move left and right to scrape and clean the impurities filtered and intercepted on the filter component inside the filter mechanism, so as to avoid the clogging of the filter holes on the filter component affecting the normal filtering use.
