[0002] Leaching mother liquor refers to the solution containing target metal ions or other useful components obtained after the ore has undergone leaching and dissolution steps in hydrometallurgy or bioleaching. This solution may undergo concentration, crystallization, centrifugation and other steps in subsequent processing, but it still contains some leached components and a lot of impurities.

[0003] Currently, the mother liquor obtained from leaching during rare earth mining is used for impurity removal before precipitation or extraction. Due to the large peak leaching volume of the mother liquor, the precipitation or extraction workshops are generally large-scale, resulting in large investments in infrastructure and equipment. Furthermore, the impurity removal agents and power consumption during the extraction process are enormous, leading to high extraction costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, the processing scale of general sedimentation or extraction workshops is relatively large, resulting in significant investment in infrastructure and equipment. Furthermore, the removal of impurities and the consumption of power during the extraction process are substantial, leading to high extraction costs. This utility model proposes a rare earth mine leaching mother liquor concentration device.

[0025] The following is combined with Figure 1-7 This application will be described in further detail.

[0026] This application discloses a rare earth mine leaching mother liquor concentration device. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 7 A rare earth mine leaching mother liquor concentration device includes a multi-media filter 1, a precision filter 2, a primary RO membrane 3, a secondary RO membrane 23, and a high-pressure pump 24. The multi-media filter 1, precision filter 2, primary RO membrane 3, secondary RO membrane 23, and high-pressure pump 24 are fixedly connected. An inlet pipe 4 is fixedly connected to the surface of the multi-media filter 1, and a first outlet pipe 5 is fixedly connected to the surface of the multi-media filter 1. A booster pump 6 is fixedly installed at one end of the first outlet pipe 5. A guide pipe 7 is fixedly connected to the output end of the booster pump 6. One end of the guide pipe 7 is fixedly connected to one side of the precision filter 2. A filtration mechanism 8 is provided in the inner cavity of the multi-media filter 1.

[0027] The filtration mechanism 8 includes a support plate 801, the surface of which is fixedly connected to the inner wall of the multi-media filter 1. A first filter cylinder 802 is fixedly connected to one side of the support plate 801. A first filter hole 803 is formed on the surface of the first filter cylinder 802. A second filter cylinder 804 is fitted inside the inner cavity of the first filter cylinder 802. One end of the second filter cylinder 804 is fixedly connected to one side of the support plate 801. A second filter hole 805 is formed on the surface of the second filter cylinder 804. One end of the first outlet pipe 5 communicates with the inner cavity of the second filter cylinder 804. In this rare earth mine leaching mother liquor concentration equipment, the target wastewater enters the interior of the multi-media filter 1 through the inlet pipe 4 via a booster pump. Large particles of silt and other impurities in the wastewater are first blocked by the first filter cartridge 802 in the filtration mechanism 8. The second filter cartridge 804 can further block the silt in the wastewater. The aperture of the second filter hole 805 is smaller than that of the first filter hole 803. The mother liquor filtered in the cavity of the second filter cartridge 804 is transported to the precision filter 2 through the first outlet pipe 5 and the guide pipe 7 by the booster pump 6. The multi-media filter 1 has a simple and compact structure, which can effectively reduce the amount of mother liquor entering the sedimentation or extraction workshop, stabilize the rare earth element concentration in the mother liquor, thereby reducing the investment in basic equipment in the sedimentation or extraction workshop and reducing the consumption of reagents and power during the extraction process, thus reducing the extraction cost.

[0028] Reference Figure 2A cylinder 9 is fixedly installed on the top of the multi-media filter 1. A push rod 10 is fixedly connected to the output end of the cylinder 9. A push plate 11 is fixedly connected to one end of the push rod 10. The inner cavity of the push plate 11 is slidably connected to the surface of the first filter cylinder 802. The surface of the push plate 11 is slidably connected to the inner wall of the multi-media filter 1. Through the push plate 11, the cylinder 9 can drive the push rod 10 to push the push plate 11 to move from top to bottom. On the one hand, the push plate 11 can push out the mud and impurities separated inside the multi-media filter 1. On the other hand, the push plate 11 can scrape and clean the surface of the first filter cylinder 802 and the inner wall of the multi-media filter 1 that are in direct contact with the mother liquor, thereby improving the efficiency of waste discharge.

[0029] Reference Figure 2 An adaptive telescopic rod 12 is fixedly connected to one side of the push plate 11. One end of the adaptive telescopic rod 12 is fixedly connected to the inner wall of the multi-media filter 1. When the position of the push plate 11 is lowered or raised, the adaptive telescopic rod 12 will extend or retract synchronously to improve the stability of the push plate 11.

[0030] Reference Figure 3 and Figure 4 A first discharge port 13 is provided on one side of the support plate 801. An adjusting plate 14 is rotatably connected to the inner cavity of the multi-media filter 1. A second discharge port 15 is provided on one side of the adjusting plate 14. A positioning plate 16 is fixedly connected to the surface of the adjusting plate 14. A limiting groove 17 is provided on the surface of the multi-media filter 1. The surface of the positioning plate 16 is slidably connected to the inner wall of the limiting groove 17. The adjusting plate 14 can rotate along the inner cavity of the multi-media filter 1 through the setting. The rotation range of the adjusting plate 14 is limited by the cooperation of the positioning plate 16 and the limiting groove 17. When the adjusting plate 14 is not adjusted, the position of the second discharge port 15 is offset from the position of the first discharge port 13, so that the mud and sand impurities inside the multi-media filter 1 accumulate. Pushing the positioning plate 16 causes the adjusting plate 14 to rotate, and the positions of the first discharge port 13 and the second discharge port 15 coincide, realizing the discharge of mud and sand impurities.

[0031] Reference Figure 5 A plate 18 is fixedly connected to the surface of the multi-media filter 1. Positioning holes 19 are provided on one side of both the plate 18 and the positioning plate 16. Fixing bolts 20 are movably inserted into the inner wall of the positioning holes 19. Through the fixing bolts 20, the position of the adjusting plate 14 remains unchanged during the filtration process of the multi-media filter 1. The positions of the positioning plate 16 and the plate 18 correspond to each other, and the two positioning holes 19 are connected. The adjusting plate 14 is fixed by the fixing bolts 20, thereby improving the stability of the adjusting plate 14.

[0032] Referring to the figure, a purification layer 21 is fixedly connected to the inner wall of the precision filter 2, and a second outlet pipe 22 is fixedly connected to one side of the precision filter 2. Through the purification layer 21, which can use filter materials such as activated carbon, the microbial particles in the mother liquor are further filtered, and then the mother liquor is discharged through the second outlet pipe 22.

[0033] Working principle: The target wastewater enters the multi-media filter 1 through the inlet pipe 4 via a booster pump. Large particles of silt and other impurities in the wastewater are first blocked by the first filter cartridge 802 in the filtration mechanism 8. The second filter cartridge 804 can further block the silt in the wastewater. The pore size of the second filter hole 805 is smaller than that of the first filter hole 803. The mother liquor filtered in the cavity of the second filter cartridge 804 is transported to the precision filter 2 through the first outlet pipe 5 and the guide pipe 7 by the booster pump 6. The purification layer 21 can use filter materials such as activated carbon to filter out microbial particles in the mother liquor. After a single filtration step, the mother liquor is discharged through the second outlet pipe 22 and then pumped to the first-stage RO membrane 3 by the high-pressure pump 24. The water produced by the first-stage RO membrane 3 after concentration enters the second-stage RO membrane 23. The rare earth elements in the mother liquor are concentrated and intercepted and enter the sedimentation or extraction process section as concentrated water from the first-stage RO membrane 3 for ore extraction. The multi-media filter 1 has a simple and compact structure, which can effectively reduce the amount of mother liquor entering the sedimentation or extraction workshop, stabilize the rare earth element concentration in the mother liquor, thereby reducing the investment in basic equipment in the sedimentation or extraction workshop and reducing the consumption of reagents and power during the ore extraction process, thus reducing the ore extraction cost.
