[0017] A device for extracting rare metals, further comprising the following steps:

[0018] Step 1: Place the material to be extracted with rare metals in the rotating barrel, cover it with a fixed cover, ensure that the fixed cover is tightly connected to the rotating barrel, flip the barrel cover to rotate around the flip connection block to close it, open the closing cover, pour aqua regia into the liquid storage barrel through the liquid inlet hole, and the aqua regia enters the rotating barrel through the holes on the rotating barrel and the fixed cover to fully contact with the material, and then use the closing cover to close the liquid inlet hole through the thread on the liquid inlet hole;

DETAILED DESCRIPTION

[0035] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0036] Example 1

[0037] See also Figure 1-8 , a rare metal extraction device, comprising a support column 1, a connecting ring 2 is fixedly connected to one side surface of the support column 1, a liquid storage barrel 3 is fixedly connected to one side surface of the connecting ring 2, a liquid discharge port 4 is provided on the lower surface of the liquid storage barrel 3, a rotating mechanism 5 is provided on the inner surface of the liquid storage barrel 3, a flushing mechanism 6 is provided on the upper surface of the liquid storage barrel 3, a barrel cover 7 is provided on the upper surface of the flushing mechanism 6, a liquid inlet hole 8 is provided on the upper surface of the barrel cover 7, and a closing cover 9 is slidably connected to the upper surface of the liquid inlet hole 8;

[0038] The flushing mechanism 6 includes a guide ring 601, a fixed ring 602, a high-pressure water inlet 603, a connecting buckle 604, an annular water pipe 605, a high-pressure nozzle 606 and a flip connecting block 607. The upper surface of the liquid storage barrel 3 is fixedly connected with the guide ring 601, the upper surface of the guide ring 601 is fixedly connected with the fixing ring 602, one side surface of the fixing ring 602 is provided with a high-pressure water inlet 603, the inner side surface of the fixing ring 602 is fixedly connected with the connecting buckle 604, one side surface of the connecting buckle 604 is fixedly connected with the annular water pipe 605, one side surface of the annular water pipe 605 is provided with a high-pressure nozzle 606, one side surface of the fixing ring 602 is fixedly connected with the flip connecting block 607, through the guide ring 601, the fixing ring 602, the high-pressure water inlet 603, the connecting buckle 604, the annular water pipe 605, the high-pressure nozzle 606, the flip connecting block 607 605, high-pressure nozzle 606 and flip connection block 607 are set. When in use, the unique guide ring 601, annular water pipe 605 and high-pressure nozzle 606 can make the flushing water form a vortex on the barrel wall, comprehensively and efficiently remove the residual aqua regia and impurities in the liquid storage barrel, avoid the complicated process and resource waste of manual cleaning, ensure the cleanliness of the equipment, and facilitate the next use. Secondly, the components are tightly and reasonably connected. For example, the connecting buckle 604 ensures the stability of the annular water pipe 605, the fixing ring 602 connects multiple key components, so that the structure of the entire flushing mechanism is stable and reliable, the flip connection block 607 facilitates the opening and closing of the barrel cover 7, and is convenient for the operation and maintenance of the equipment. The high-pressure water inlet 603 is easy to connect to an external high-pressure water source, which provides convenience for flushing. These advantages together improve the ease of use and cleaning efficiency of the equipment.

[0039] Furthermore, the support column 1 is symmetrically arranged with six groups around the midline of the connecting ring 2, and the connecting ring 2 is arranged with four groups on one side surface of the support column 1, two of which are fixedly connected to the liquid storage barrel 3. Through the arrangement of the support column 1 and the connecting ring 2, when in use, the support column 1 is symmetrically arranged with six groups around the midline of the connecting ring 2. This symmetrical distribution method can make the force of the entire device more uniform. When the rotating mechanism 5 drives the rotating barrel 504 to rotate for rare metal extraction, the equipment may generate certain vibrations. The symmetrical support column 1 can better resist these vibrations and ensure the stability of the equipment. During the long-term use of the connecting ring 2, even if a certain connection point is slightly loose or damaged, the other connection points can still ensure the stability of the liquid storage barrel 3, reducing the possibility of equipment failure due to connection problems, and is also conducive to the maintenance and repair of the equipment.

[0040] Furthermore, the drain port 4 is arranged on one side of the motor, and the lower bottom surface of the liquid storage barrel 3 presents a certain curvature, ensuring that the motor will not interfere with the liquid when it flows out from the drain port 4. Through the setting of the drain port 4, when in use, this design conforms to the principles of fluid mechanics, and the curvature can make the liquid gather and flow out more smoothly, avoiding liquid residue at the bottom of the barrel, ensuring the efficiency of the drainage process, and allowing the liquid to be discharged as completely as possible.

[0041] Furthermore, the radius and thickness of the guide ring 601 are consistent with those of the liquid storage barrel 3, and a plurality of guide grooves are provided on the inner surface of the guide ring 601. When the high-pressure nozzle 606 performs water spraying, the liquid will be flushed in a vortex on the barrel wall. By setting the guide ring 601, when in use, it can be ensured that the flushing water forms a stable flow path in the space between the guide ring 601 and the liquid storage barrel 3. This vortex-like flushing method is like a powerful vortex, which can flush the inner wall of the liquid storage barrel 3 in all directions. Compared with ordinary straight water flow flushing, the vortex can better cover every corner of the barrel wall, effectively remove the aqua regia and impurities remaining in the liquid storage barrel 3, and improve the flushing efficiency.

[0042] Furthermore, the annular water pipe 605 is fixedly connected to the annular water pipe 605 through a connecting buckle 604, and the connecting buckle 604 is symmetrically arranged in six groups with the mid-vertical line of the annular water pipe 605, and the high-pressure nozzles 606 are symmetrically arranged in six groups with the mid-vertical line of the guide ring 601, and are consistent with the inclination angle of the guide groove, to ensure that the flushing water flow is in a vortex state. Through the setting of the high-pressure nozzles 606, it is ensured that the flushing water flow can be in a vortex state during use. The symmetrically distributed high-pressure nozzles 606 can make the flushing water form a vortex evenly under the guidance of the guide ring 601, avoiding the situation where the local flushing force is too large or too small. The design that is consistent with the inclination angle of the guide groove further ensures that the water flow can flow according to the expected vortex path, so that the flushing water flow can comprehensively and evenly flush the inner wall of the liquid storage barrel 3, thereby more efficiently removing residual aqua regia and impurities and improving the flushing effect.

[0043] Furthermore, the flip connection block 607 and the high-pressure water inlet 603 are symmetrically arranged on both sides of the fixed ring 602, and the barrel cover 7 is rotatably connected to the surface of one side of the flip connection block 607. The barrel cover 7 can be flipped ninety degrees by the setting of the flip connection block 607. Through the setting of the flip connection block 607, when in use, the flip connection block 607 can allow the barrel cover 7 to be flipped 90 degrees, which provides convenience for the operation of the equipment. When cleaning or checking the internal components after the equipment is used, this large-angle flip also allows the operator to access the inside of the liquid storage barrel 3 without hindrance, greatly improving the operating efficiency.

[0044] Furthermore, a thread is provided on one side surface of the liquid inlet hole 8 above the barrel cover 7, and the closing cover 9 is rotatably connected to the liquid inlet hole 8 through the thread, so that the closing is achieved after the aqua regia is poured in. Through the arrangement of the barrel cover 7 and the liquid inlet hole 8, good sealing can be provided during use, and the threaded connection sealing method can effectively prevent the leakage of aqua regia, ensure that the liquid inside the equipment is in a closed environment, and ensure the safe and stable operation of the equipment.

[0045] Furthermore, the rotating mechanism 5 includes a waterproof shell 501, a rotating motor 502, a rotating block 503, a rotating barrel 504 and a fixed cover 505. The lower surface of the liquid storage barrel 3 is fixedly connected to the waterproof shell 501, the inner surface of the waterproof shell 501 is fixedly connected to the rotating motor 502, the upper surface of the rotating motor 502 is fixedly connected to the rotating block 503, the upper surface of the rotating block 503 is fixedly connected to the rotating barrel 504, and the upper surface of the rotating barrel 504 is slidably connected to the fixed cover 505. Through the arrangement of the waterproof shell 501, the rotating motor 502, the rotating block 503, the rotating barrel 504 and the fixed cover 505, when in use, the rotation of the rotating barrel 504 allows the rare metal material to be extracted placed therein to be fully mixed with the aqua regia. This sufficient mixing can accelerate the dissolution and extraction process of the rare metals. Compared with the static immersion method, the extraction efficiency is greatly improved, and the material and the aqua regia can more fully contact and react in a dynamic rotating environment.

[0046] Furthermore, multiple groups of holes are provided on the outer surfaces of the rotating barrel 504 and the fixed cover 505, and the holes allow aqua regia to enter the interior of the rotating barrel 504 and enable the objects inside to fully contact with the aqua regia. A thread is provided on the upper outer side of the rotating barrel 504, and the fixed ring 602 is rotatably connected to the rotating barrel 504 through the thread. Through the arrangement of the rotating barrel 504 and the fixed cover 505, when in use, the aqua regia can smoothly enter the interior of the rotating barrel 504, ensuring that all parts of the material can be fully immersed in the aqua regia. This full contact greatly improves the reaction efficiency, is beneficial to the dissolution of rare metals from the material, speeds up the extraction process, and enables better extraction effects to be obtained in a relatively short time.

[0047] Example 2

[0048] A method for using a device for extracting rare metals, using the device for extracting rare metals in Example 1, further comprising the following steps:

[0049] Step 1: Place the material to be extracted with rare metals in the rotating barrel 504, cover it with the fixed cover 505, ensure that the fixed cover 505 is tightly connected to the rotating barrel 504, flip the barrel cover 7 to rotate around the flip connection block 607 to close, open the closing cover 9, pour aqua regia into the liquid storage barrel 3 through the liquid inlet hole 8, and the aqua regia enters the rotating barrel 504 through the holes on the rotating barrel 504 and the fixed cover 505 to fully contact with the material, and then use the closing cover 9 to close the liquid inlet hole 8 through the thread on the liquid inlet hole 8;

[0050] Step 2: Start the rotating motor 502 in the rotating mechanism 5. The rotating motor 502 drives the rotating barrel 504 to rotate through the rotating connecting block 503, so that the material in the rotating barrel 504 and the aqua regia are fully mixed and reacted during the rotation process, accelerating the dissolution and extraction process of the rare metals. During the extraction process, the speed and rotation time of the rotating motor 502 can be controlled as needed to ensure the extraction effect;

[0051] Step 3: After the extraction is completed, the drain port 4 is opened. Since the bottom surface of the liquid storage barrel 3 has a certain curvature and the drain port 4 is arranged on one side of the motor, the liquid will not be disturbed by the motor when it is discharged, so that the solution containing rare metals is discharged from the drain port 4 for subsequent treatment;

[0052] Step 4: Connect an external high-pressure water source to the high-pressure water inlet 603 of the flushing mechanism 6, and the high-pressure water is sprayed out from the high-pressure nozzle 606 through the annular water pipe 605. Since the inner surface of the guide ring 601 has a guide groove and the angle of the high-pressure nozzle 606 matches the inclination angle of the guide groove, the sprayed water forms a vortex on the barrel wall, flushing the inside of the liquid storage barrel 3 to remove residual aqua regia and impurities. After the flushing is completed, turn off the high-pressure water source and dry the equipment in the air or wipe it dry for next use;

[0053] Step 5: First select a suitable extractant, mix it with the solution containing rare metals, oscillate to allow the rare metals to enter the extractant phase, then let it stand to separate the layers, and then treat the extract phase. The rare metals can be transferred to a new solution through operations such as back extraction. After that, use chemical reduction method, add a suitable reducing agent to reduce the rare metal ions to a single substance, and then separate the metal by filtration and other methods.

[0054] Working principle: through the arrangement of the flushing mechanism 6 and the rotating mechanism 5, when the rare metals are extracted, the material of the rare metal to be extracted is placed in the rotating barrel 504, and the fixed cover 505 is covered to ensure a tight connection, and the barrel cover 7 is turned around the turning connection block 607 to close, and the closing cover 9 is opened, and aqua regia is poured into the liquid storage barrel 3 from the liquid inlet hole 8. The aqua regia enters the rotating barrel 504 through the holes on the rotating barrel 504 and the fixed cover 505 and fully contacts with the material. Finally, the closing cover 9 is used to close the liquid inlet hole 8 through the thread on the liquid inlet hole 8. This process prepares for the subsequent extraction of rare metals, so that the material can be fully immersed in the aqua regia, and the rotating motor 502 in the rotating mechanism 5 is started. The rotating motor 502 drives the rotating barrel 504 to rotate through the rotating connection block 503. During the rotation process, the material and the aqua regia are fully mixed and reacted, which accelerates the dissolution and extraction of the rare metals. By controlling the rotation speed and rotation time of the rotating motor 502, the extraction effect can be optimized according to the properties of the material and the rare metal, ensuring that as many rare metals as possible are dissolved from the material, and extracting After the extraction is completed, the drain port 4 is opened. Since the bottom surface of the liquid storage barrel 3 has a certain curvature and the drain port 4 is arranged on the side of the motor, the liquid will not be disturbed by the motor when it is discharged. The solution containing rare metals can be discharged smoothly from the drain port 4, providing a solution containing target rare metals for the subsequent processing flow, while avoiding the residual solution from affecting the next use of the equipment. The external high-pressure water source is connected to the high-pressure water inlet 603 of the flushing mechanism 6, and the high-pressure water enters the annular water pipe 605 connected to the inner side of the fixing ring 602 through the connecting buckle 604, and then The high-pressure nozzle 606 on one side surface of the annular water pipe 605 sprays out. Since there is a guide groove on the inner surface of the guide ring 601 and the angle of the high-pressure nozzle 606 matches the inclination angle of the guide groove, the sprayed water is in a vortex shape on the barrel wall, and the inside of the liquid storage barrel 3 is fully rinsed to effectively remove residual aqua regia and impurities. After the rinsing is completed, the high-pressure water source is turned off, and the equipment is dried or wiped dry for next use. This flushing method avoids the tediousness of manual cleaning and waste of resources. The model of the rotating motor 502 is YE2-132S-4.

A method for using a device for extracting rare metals, characterized in that: The device for extracting rare metals according to any one of claims 1 to 9 further comprises the following steps: Step 1: Place the material to be extracted with rare metals in the rotating barrel (504), cover it with a fixed cover (505), ensure that the fixed cover (505) is tightly connected to the rotating barrel (504), flip the barrel cover (7) to rotate around the flip connection block (607) to close, open the closing cover (9), pour aqua regia into the liquid storage barrel (3) through the liquid inlet hole (8), and the aqua regia enters the rotating barrel (504) through the holes on the rotating barrel (504) and the fixed cover (505) to fully contact with the material, and then use the closing cover (9) to close the liquid inlet hole (8) through the thread on the liquid inlet hole (8); Step 2: Start the rotating motor (502) in the rotating mechanism (5), and the rotating motor (502) drives the rotating barrel (504) to rotate through the rotating connecting block (503), so that the materials in the rotating barrel (504) and the aqua regia are fully mixed and reacted during the rotation process, thereby accelerating the dissolution and extraction process of the rare metals. During the extraction process, the rotation speed and rotation time of the rotating motor (502) can be controlled as needed to ensure the extraction effect; Step 3: After the extraction is completed, the drain port (4) is opened. Since the bottom surface of the liquid storage barrel (3) has a certain curvature and the drain port (4) is arranged on one side of the motor, the liquid will not be disturbed by the motor when it is discharged, so that the solution containing rare metals is discharged from the drain port (4) for subsequent treatment; Step 4: Connect an external high-pressure water source to the high-pressure water inlet (603) of the flushing mechanism (6), and the high-pressure water is ejected from the high-pressure nozzle (606) through the annular water pipe (605). Since the inner surface of the guide ring (601) has a guide groove and the angle of the high-pressure nozzle (606) matches the inclination angle of the guide groove, the ejected water forms a vortex on the barrel wall, flushing the inside of the liquid storage barrel (3) to remove the residual aqua regia and impurities. After the flushing is completed, turn off the high-pressure water source and dry the equipment in the air or wipe it dry for next use; Step 5: First select a suitable extractant, mix it with the solution containing rare metals, oscillate to allow the rare metals to enter the extractant phase, then let it stand to separate the layers, and then treat the extract phase. The rare metals can be transferred to a new solution through operations such as back extraction. After that, use chemical reduction method, add a suitable reducing agent to reduce the rare metal ions to a single substance, and then separate the metal by filtration and other methods.
