Abstract
Description
Technical Field
[0001] The utility model relates to the field of ionic rare earth ore mining, in particular to an ionic rare earth mother liquor extraction and filtering device. Background Art
[0002] At present, ionic rare earth ores are mined by in-situ leaching technology. Ionic rare earth mines are unique to my country. The in-situ leaching process is to inject leaching liquid into the appropriate position above the ore body to guide the flow of the leaching liquid, so that it can fully exchange and penetrate with the ore body, and finally obtain rare earth mother liquor containing rare earths through ion exchange. For different rare earth ore bodies, the guiding method of rare earth mother liquor is also different. There are currently two methods. One is to drill holes at the bottom of the rare earth ore body and use pipelines to lead out the rare earth mother liquor, and the other is to dig multiple groups of tunnels at the bottom of the rare earth ore body to collect and lead out the rare earth mother liquor. At present, the method of digging multiple groups of tunnels to collect and lead out the rare earth mother liquor is that after the leaching liquid exchanges ions with the ore body, under the action of gravity, the rare earth mother liquor flows downward through the tunnel and flows out for collection. The efficiency of draining and collecting the rare earth mother liquor in this way is low. If the drainage is not thorough, a large amount of rare earth mother liquor will remain in the ore body. At the same time, the rare earth mother liquor collected by drainage contains more sand and gravel impurities.

The rare earth mother liquor extracted from the lane by the rare earth mother liquor extraction component 1 passes through the first step layer 14 and the second step layer 15 and flows from the filter bag 11 into the box body 10. The filter bag 11 can filter out the stones and sand in the rare earth mother liquor. The left part of the second step layer 15 is provided with a square filter bag installation position 16 for placing the filter bag 11. The filter bag 11 is a square body. The bottom of the filter pocket 11 is a filter net 17, which is used to filter sand and gravel in the rare earth mother liquor. A limiting edge layer 18 extends outside the filter pocket 11 to play a limiting role. When the filter pocket 11 is installed on the filter pocket installation position 16, it plays a limiting role to prevent it from falling. A gripping handle 19 is provided at the bottom center of the filter pocket 11.
