Description

Technical Field

[0001] This invention belongs to the technical field of rare earth extraction and separation, and relates to a rare earth extraction and separation method and apparatus. Background Technology

[0002] Rare earth elements are known as "industrial vitamins" and have become an extremely important strategic resource. With the continuous development of technology in modern society, rare earth elements have been widely used in various fields. However, rare earth raw materials require extraction and separation processes during processing.

[0003] Existing methods for processing rare earth raw materials using extraction and separation typically involve first mixing the rare earth material with the extraction liquid to allow it to react, and then allowing the reacted material to stand, causing the metal material and the filtrate to separate into layers. However, existing technologies usually require mixing equipment for mixing, and after mixing, the material is transported to a settling tank for separation. During the mixing process, the addition of rare earth material, which contains solid substances, generates some solid waste and impurities, which are difficult to remove using the above method. Summary of the Invention

[0004] In order to overcome the shortcomings of existing methods in separating and removing waste and impurities, the present invention provides a rare earth extraction and separation method and apparatus that can separate and remove waste and impurities.

[0005] The technical solution is as follows: A rare earth extraction and separation device includes a separation cylinder, a support, a feeding pipe, a liquid delivery pipe, a liquid delivery cylinder, a transfer pipe, a reaction mechanism, and a separation mechanism. Multiple supports for supporting the separation cylinder are evenly spaced along the circumference of the lower part of the separation cylinder. An opening for discharging the separated liquid is provided at the bottom of the separation cylinder. A feeding pipe is connected to the top of the separation cylinder, and a liquid delivery cylinder is connected to the top of the separation cylinder. A liquid delivery pipe is connected to the liquid delivery cylinder, and a one-way valve is provided on the liquid delivery cylinder. A transfer pipe connects the liquid delivery cylinder and the top of the separation cylinder. The separation cylinder is equipped with a reaction mechanism for assisting the reaction between the rare earth material and the extraction liquid, and a separation mechanism for separating the reacted liquid from the waste material.

[0006] Furthermore, the reaction mechanism includes a servo motor, a stirring shaft, and a partition. The upper part of the separation cylinder is connected to the partition, which separates the upper space of the separation cylinder from the rest of the space. The space separated in the upper part of the separation cylinder is a mixing chamber. Four through slots are evenly spaced on the partition, and four solenoid valves are installed at the through slots. A servo motor is installed in the middle of the top of the separation cylinder. The output shaft of the servo motor is connected to the stirring shaft, which extends into the mixing chamber.

[0007] Furthermore, the separation mechanism includes a drive shaft, a second partition, a filter cylinder, a connecting cylinder, a collecting cylinder, a liquid inlet pipe, a swivel disc, and a spiral scraper. The lower part of the separation cylinder is rotatably connected to the second partition, which separates the space in the lower part of the separation cylinder. The space separated in the lower part of the separation cylinder is the separation chamber. The bottom of the stirring shaft is connected to the drive shaft, which passes through the first partition and is connected to the second partition. The drive shaft is rotatably connected to the first partition. The bottom of the drive shaft is connected to the swivel disc. The bottom of the second partition is connected to the filter cylinder. Multiple liquid inlet pipes are evenly spaced along the circumference of the second partition. The lower part of the separation cylinder is connected to the connecting cylinder, which is rotatably connected to the filter cylinder. The connecting cylinder is located at the opening of the separation cylinder and there is a gap between it and the opening for liquid to flow out. The collecting cylinder is slidably connected inside the connecting cylinder. The upper part of the connecting cylinder is connected to the spiral scraper, which is in close contact with the inner wall of the filter cylinder.

[0008] Furthermore, it also includes an automatic proportioning mechanism, which includes a sliding frame, a float and a piston block. The upper part of the separation cylinder is slidably connected to the sliding frame, the bottom of the sliding frame extends into the mixing chamber and is connected to the float, and the lower part of the liquid delivery cylinder is slidably connected to the piston block, which is connected to the sliding frame.

[0009] Furthermore, it also includes a storage mechanism, which includes a conical feed hopper, a baffle plate, an elastic element, and a pusher block. The upper part of the connecting cylinder is connected to the conical feed hopper, and the bottom of the conical feed hopper is slidably connected to the baffle plate. Two elastic elements are connected between the baffle plate and the connecting cylinder, and a pusher block for pushing the baffle plate to move is connected to the collecting cylinder.

[0010] Furthermore, it also includes a locking mechanism, which includes a wedge-shaped stop, an elastic element two, and a dial. The wedge-shaped stop is slidably connected to the collecting cylinder, and the elastic element two is connected between the wedge-shaped stop and the collecting cylinder. The dial is connected to the wedge-shaped stop and is slidably connected to the collecting cylinder.

[0011] Furthermore, it also includes an auxiliary mechanism, which includes a drive gear, a stirring shaft II, and a driven gear. The output shaft of the servo motor is connected to the drive gear. Multiple stirring shaft IIs are rotatably connected in a uniform circumferential manner inside the mixing chamber. Each stirring shaft II is connected to a driven gear at its top, and the driven gear meshes with the drive gear.

[0012] Furthermore, it also includes an exhaust gas filtration mechanism, which includes an exhaust pipe, an exhaust cylinder, a fan, and a multi-stage filter disc. The exhaust cylinder is connected to the separation cylinder, and an exhaust pipe connects the top of the exhaust cylinder to the upper part of the separation cylinder. A fan is installed in the lower part of the exhaust cylinder, and a multi-stage filter disc is installed in the middle part of the exhaust cylinder.

[0013] This invention also provides a rare earth extraction and separation method, the specific steps of which are as follows:

[0014] S1: Add rare earth material and extract to the mixing chamber of the separation cylinder;

[0015] S2: Control the servo motor to start and drive the stirring shaft to rotate, mix the rare earth material and the extract, and make the rare earth material and the extract react;

[0016] S3: Open the solenoid valve, and the reacted material falls into the second partition.

[0017] S4: The material at the two baffles enters the sling plate through the liquid inlet pipe;

[0018] S5: The stirring shaft drives the drive shaft, the swivel disc, and the filter cartridge to rotate;

[0019] S6: The rotating disc throws the material out, and the rotating filter cartridge throws the material out. The mixture in the material passes through the filter cartridge, while impurities and waste liquid remain in the filter cartridge, thus achieving the extraction and separation of rare earth elements.

[0020] The beneficial effects of the present invention are as follows: 1. During the operation of the present invention, after the materials are mixed, the solenoid valve can be opened directly to send them into the separation chamber for separation. During the separation process, the mixed liquid and solid residue waste can be separated, thereby achieving the effect of separating the mixed liquid and solid waste.

[0021] 2. During operation, the present invention can automatically add extraction liquid according to the amount of rare earth material added, eliminating the need for manual proportioning and making the operation more convenient.

[0022] 3. When the collection cylinder is removed, the present invention can block the conical feed hopper with a baffle plate so that the enriched rare earth elements can be stored through the conical feed hopper, so as to prevent the rare earth elements from falling into the connecting cylinder, which would make collection more troublesome.

Detailed Implementation

[0040] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0041] A rare earth extraction and separation device, such as Figures 1-8As shown, the system includes a separation cylinder 1, a support 2, a feeding pipe 3, a liquid delivery pipe 4, a liquid delivery cylinder 41, a transfer pipe 42, a reaction mechanism, and a separation mechanism. Multiple supports 2 are evenly spaced along the circumference of the lower outer side of the separation cylinder 1 to support it. An opening is provided at the bottom of the separation cylinder 1 to discharge the separated liquid. The top of the separation cylinder 1 is connected to the feeding pipe 3, and the top of the separation cylinder 1 is connected to the liquid delivery cylinder 41. A liquid delivery pipe 4 is connected to the liquid delivery cylinder 41, and a one-way valve is provided on the liquid delivery pipe 4. A transfer pipe 42 connects the liquid delivery cylinder 41 to the top of the separation cylinder 1, allowing the extract to be added from the liquid delivery cylinder 41 into the liquid delivery pipe 4. The separation cylinder 1 is equipped with a reaction mechanism to assist the reaction between the rare earth material and the extract, and a separation mechanism to separate the reacted liquid from the waste material.

[0042] like Figure 5 As shown, the reaction mechanism includes a servo motor 51, a stirring shaft 52, and a partition 53. The upper part of the separation cylinder 1 is connected to the partition 53, which separates the upper space of the separation cylinder 1 from the rest of the space. The space separated in the upper part of the separation cylinder 1 is a mixing chamber. Four through slots are evenly spaced on the partition 53 so that the material can fall into the lower part of the partition 53. Four solenoid valves are installed at the through slots. The servo motor 51 is installed in the middle of the top of the separation cylinder 1. The output shaft of the servo motor 51 is connected to the stirring shaft 52. The stirring shaft 52 extends into the mixing chamber. The rotation of the stirring shaft 52 can stir the material in the mixing chamber.

[0043] like Figures 6-8As shown, the separation mechanism includes a drive shaft 61, a second partition 62, a filter cartridge 63, a connecting cylinder 641, a collecting cylinder 64, a liquid inlet pipe 65, a slinger 66, and a spiral scraper 67. The lower part of the separation cylinder 1 is rotatably connected to the second partition 62, which separates the lower space within the separation cylinder 1. This separated space forms the separation chamber. The bottom of the stirring shaft 52 is connected to the drive shaft 61, which passes through the first partition 53 and connects to the second partition 62. The drive shaft 61 and the first partition 53 are rotatably connected. The bottom of the drive shaft 61 is connected to the slinger 66, which is used to throw out the material. The bottom of the second partition 62 is connected to the filter cartridge 63, which is used to separate the rare earth material from the remaining liquid. Multiple liquid inlet pipes 65 are evenly spaced along the upper circumference to transfer the material above the partition plate 62 to the top of the sling plate 66. A connecting cylinder 641 is connected to the lower part of the separation cylinder 1. The connecting cylinder 641 is rotatably connected to the filter cylinder 63. The connecting cylinder 641 is located at the opening of the separation cylinder 1 and there is a gap between it and the opening. This gap is used for liquid outflow. A collecting cylinder 64 is slidably connected inside the connecting cylinder 641. The collecting cylinder 64 is used to collect rare earth elements. Filter holes are evenly spaced at the bottom of both the collecting cylinder 64 and the connecting cylinder 641 to filter out the liquid. A spiral scraper 67 is connected to the upper part of the connecting cylinder 641. The spiral scraper 67 is in close contact with the inner wall of the filter cylinder 63 to scrape off the material attached to the inner wall of the filter cylinder 63.

[0044] This device can be used when rare earth elements need to be extracted and separated. In operation, the rare earth material is first added to the mixing chamber at the top of the separation cylinder 1 through the feeding pipe 3. Then, the extract is added to the delivery cylinder 41 through the delivery pipe 4. The extract in the delivery cylinder 41 then enters the mixing chamber at the top of the separation cylinder 1 through the transfer pipe 42. The extract and rare earth material then react in the mixing chamber to extract the rare earth elements. Before the reaction, the servo motor 51 can be controlled to drive the stirring shaft to rotate, thus stirring the extract and rare earth material and assisting in the extraction process. After the reaction with the rare earth material is complete, the solenoid valve can be opened to allow the material to fall above the second partition 62. Once it has completely fallen in, the solenoid valve can be closed. Then, the extraction liquid and rare earth material can be added to the mixing chamber again for further reaction. The material above the second partition 62 will enter the sling plate 66 through the liquid inlet pipe 65. The rotating stirring shaft drives the drive shaft 61 to rotate, which in turn drives the sling plate 66 to rotate. The rotating sling plate 66 throws the material above it to the filter cartridge 63. Simultaneously, the rotation of the drive shaft 61 also rotates the second partition 62. The rotation of filter cylinder 62 drives the rotation of filter cylinder 63. As filter cylinder 63 rotates, it also agitates the material adhering to its interior. During this agitation, the liquid mixture in the material passes through filter cylinder 63, while waste is blocked by filter cylinder 63 and remains on its inner wall. As filter cylinder 63 rotates, the waste adhering to its inner wall is squeezed downwards by the spiral scraper 67, causing it to fall into collection cylinder 64 for collection. The filter holes in collection cylinder 64 and connecting cylinder 641 can filter out the residual liquid mixture in the waste. The collection device can be placed at the bottom of separation cylinder 1. Both the filtered mixture and the mixture passing through the filter cartridge 63 fall into the collection device to collect the mixture. The collection cartridge 64 can collect the waste. After processing, the solenoid valve can be opened again to allow the reacted material to fall and continue the separation operation. By repeating this process, the rare earth material can be extracted and separated using this device. During the extraction and separation process, the subsequent separation operation can be carried out simultaneously with the mixing and reaction, without the need for separate operations. This makes the operation more convenient, the extraction efficiency is higher, and the waste mixed in with the material can be removed.

[0045] Based on Example 1, such as Figure 9 and Figure 10As shown, it also includes an automatic proportioning mechanism, which includes a sliding frame 71, a float 72, and a piston block 73. The sliding frame 71 is slidably connected to the upper part of the separation cylinder 1. The bottom of the sliding frame 71 extends into the mixing chamber in the upper part of the separation cylinder 1 and is connected to the float 72. As the amount of material in the mixing chamber increases, the float 72 can float up. The piston block 73 is slidably connected to the lower part of the liquid delivery cylinder 41. The piston block 73 is connected to the sliding frame 71. The piston block 73 can squeeze the extract in the liquid delivery cylinder 41 to the transmission pipe 42 when it moves up.

[0046] During operation, the liquid delivery pipe 4 is used to fill the liquid delivery cylinder 41 with extractant. As rare earth material is added, the rare earth material in the mixing chamber increases, which can push the float 72 upward. When the float 72 moves upward, it can drive the sliding frame 71 upward. The upward movement of the sliding frame 71 drives the piston block 73 upward. The upward movement of the piston block 73 can send the extractant in the liquid delivery cylinder 41 into the mixing chamber through the transmission pipe 42. In this way, the extractant can be added automatically according to the proportion of rare earth material added, without the need for manual proportioning, making the operation more convenient.

[0047] like Figure 11 and Figure 12 As shown, it also includes a storage mechanism, which includes a conical feed hopper 81, a baffle plate 82, an elastic element 83, and a pusher block 84. The upper part of the connecting cylinder 641 is connected to the conical feed hopper 81, and the bottom of the conical feed hopper 81 is slidably connected to the baffle plate 82. The baffle plate 82 can block the bottom of the conical feed hopper 81. Two elastic elements 83 are connected between the baffle plate 82 and the connecting cylinder 641. The upper left side of the collecting cylinder 64 is connected to the pusher block 84. The movement of the pusher block 84 can push the baffle plate 82 to move.

[0048] like Figure 12 and Figure 13 As shown, it also includes a locking mechanism, which includes a wedge-shaped stop 91, an elastic element 92, and a dial 93. The wedge-shaped stop 91 is slidably connected to the upper right side of the collection cylinder 64. The wedge-shaped stop 91 can be locked at the connecting cylinder 641 to fix the collection cylinder 64. The elastic element 92 is connected between the wedge-shaped stop 91 and the collection cylinder 64. The dial 93 is connected to the wedge-shaped stop 91 and is slidably connected to the collection cylinder 64 so that the wedge-shaped stop 91 can be moved by operating the dial 93.

[0049] Initially, push block 84 abuts against baffle plate 82, elastic element 83 is in a compressed state, and wedge-shaped stop block 91 is locked at connecting cylinder 641 to fix collecting cylinder 64. During the process of metal falling into collecting cylinder 64, conical feed hopper 81 provides guidance. When collecting cylinder 64 contains a large amount of metal, pull dial 93 can be moved downwards, causing wedge-shaped stop block 91 to move downwards, disengaging it from collecting cylinder 64. At this point, collecting cylinder 64 can be removed. After removal, the pusher 84 no longer blocks the baffle plate 82. At this time, under the action of the elastic element 83, the baffle plate 82 resets and blocks the bottom of the conical feed hopper 81. In this way, the bottom of the conical feed hopper 81 can be automatically blocked when the collection cylinder 64 is removed. At this time, the metal will accumulate at the bottom of the conical feed hopper 81 to prevent the metal from falling into the connecting cylinder 641. When the collection cylinder 64 is put in, the pusher 84 on the collection cylinder 64 can push the baffle plate 82 to move again so that the material falls into the collection cylinder 64 again.

[0050] like Figure 14 As shown, it also includes an auxiliary mechanism, which includes a drive gear 101, a stirring shaft 102, and a driven gear 103. The output shaft of the servo motor 51 is connected to the drive gear 101. Four stirring shafts 102 are rotatably connected in a circumferentially spaced manner in the mixing chamber at the upper part of the separation cylinder 1. Each stirring shaft 102 is connected to a driven gear 103 at its top, and the driven gear 103 meshes with the drive gear 101.

[0051] When the servo motor 51 is in operation, it can drive the drive gear 101 to rotate. The rotation of the drive gear 101 can drive the driven gear 103 to rotate, thereby driving the stirring shaft 102 to rotate, so as to assist in stirring the material and causing the material to react.

[0052] like Figure 15 and Figure 16 As shown, it also includes an exhaust gas filtration mechanism, which includes an exhaust pipe 111, an exhaust cylinder 112, a fan 113, and a multi-stage filter disc 114. The exhaust cylinder 112 is connected to the upper right side of the separation cylinder 1. The exhaust pipe 111 connects the top of the exhaust cylinder 112 to the upper part of the separation cylinder 1. The fan 113 is installed in the lower part of the exhaust cylinder 112. The multi-stage filter disc 114 is installed in the middle of the exhaust cylinder 112. The multi-stage filter disc 114 is used to filter the gas in the reaction process, and the fan 113 is used to extract the gas in the reaction process.

[0053] During the reaction, waste gas is generated. At this time, the fan 113 can be controlled to operate and draw the gas into the upper part of the separation cylinder 1 through the exhaust pipe 111 so that the waste gas passes through the exhaust pipe 112 and is discharged. The waste gas passing through the exhaust pipe 112 will be filtered by the multi-stage filter disc 114, thereby purifying the waste gas.

[0054] This embodiment also provides a rare earth extraction and separation method, the specific steps of which are as follows:

[0055] S1: Add rare earth material and extract to the mixing chamber of separation cylinder 1;

[0056] S2: Control the servo motor 51 to start and drive the stirring shaft 52 to rotate, mix the rare earth material and the extract, and make the rare earth material and the extract react.

[0057] S3: Open the solenoid valve, and the reacted material falls into the partition plate 2 at position 62;

[0058] S4: The material at partition 62 enters the sling plate 66 through the liquid inlet pipe 65;

[0059] S5: The stirring shaft 52 drives the drive shaft 61, the swivel disc 66 and the filter cartridge 63 to rotate;

[0060] S6: The rotating disc 66 throws the material out, and the rotating filter cylinder 63 throws the material out. The mixture in the material passes through the filter cylinder, while impurities and waste liquid remain in the filter cylinder 63, thus realizing the extraction and separation of rare earth.

[0061] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.

A rare earth extraction and separation method based on the separation apparatus of claim 3, characterized in that, The specific steps are as follows: S1: Add rare earth material and extract to the mixing chamber of the separation cylinder (1); S2: Control the servo motor (51) to start and drive the stirring shaft (52) to rotate to mix the rare earth material and the extract, so that the rare earth material and the extract react. S3: Open the solenoid valve, and the reacted material falls into the second partition (62); S4: The material at the second partition (62) enters the sling plate (66) through the liquid inlet pipe (65); S5: The stirring shaft (52) drives the drive shaft (61), the swivel disc (66) and the filter cylinder (63) to rotate; S6: The rotating disc (66) throws the material out, and the rotating filter cylinder (63) throws the material out. The mixture in the material passes through the filter cylinder, while impurities and waste liquid remain in the filter cylinder (63), thus realizing the extraction and separation of rare earth.
