Description

Technical Field

[0001] This utility model relates to the field of praseodymium oxide and neodymium extraction technology, and in particular to an extraction device for praseodymium oxide and neodymium oxide. Background Technology

[0002] In the production and processing of praseodymium oxide and neodymium oxide, extraction is a key process for improving product purity and achieving effective separation. Its core requirement is to ensure that the raw materials and extractant react fully through efficient stirring, while ensuring the smoothness, stability and sealing of the material discharge process after extraction. If there are problems such as blockage, leakage or material residue in the discharge process, it will not only reduce production efficiency, but may also lead to environmental pollution of the extraction medium, material loss, or even affect the purity of praseodymium oxide products due to the mixing of external impurities, making it difficult to meet the quality requirements of high-purity praseodymium oxide and the need for continuous production in industrial production. Currently, various technologies related to praseodymium oxide and neodymium oxide extraction devices exist in the industry, such as a high-purity praseodymium oxide and neodymium oxide extraction device proposed in a Chinese patent, patent publication number CN218793988U. This patent, by setting up protective components, can protect the feed hopper from dust, preventing dust from falling in and affecting the material quality; at the same time, through the rotation of the motor in the stirring component driving the gears and fixed blocks to achieve the up-and-down sliding of the circular rod, in conjunction with the drive motor driving the stirring rod to rotate, a stirring action combining up-and-down and rotation is formed, solving the problem of insufficient extraction purity caused by the single stirring method and insufficient material mixing in traditional extraction devices. It has certain advantages in improving the uniformity of stirring and the effect of feed protection. However, the above patent only solves the problems of feed dust prevention and sufficient material mixing in the praseodymium oxide and neodymium oxide extraction process, and does not make targeted optimization designs for the discharge of the extracted material, which is prone to the problem of discharge port blockage, resulting in interruption of discharge.

[0003] Therefore, we propose an extraction device for praseodymium-neodymium oxide to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an extraction device for praseodymium oxide and neodymium oxide, which solves the problems of easy clogging, uneven discharge, and high material residue rate after praseodymium oxide extraction in the prior art, making it difficult to adapt to the requirements of praseodymium oxide extraction process for discharge stability and high-purity production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An extraction apparatus for praseodymium-neodymium oxide includes a stirred tank with a support fixedly mounted at the bottom end of the stirred tank, and further includes: A first motor is fixedly installed at the top of the mixing drum, and the output shaft of the first motor extends through into the interior of the mixing drum and is fixedly installed with a stirring rod. A discharge pipe is fixedly installed on one side of the bottom of the mixing drum, and a discharge structure is rotatably installed inside the discharge pipe.

[0006] Preferably, three sets of equally spaced arc-shaped stirring blades are fixedly installed on the stirring rod, and three sets of stirring blades are fixedly installed at the bottom end of the stirring rod; A turntable is fixedly installed on the side of the stirring rod near the stirring blades, and the other ends of the three sets of stirring blades are all fixedly connected to the turntable. The other ends of the three sets of arc-shaped stirring blades are all fixedly installed together with the turntable.

[0007] Preferably, a mounting base is fixedly installed on one side of the top of the discharge pipe, and a turntable is rotatably installed inside the mounting base; The first magnet assembly is fixedly installed inside the turntable.

[0008] Preferably, a second motor is fixedly mounted on the top of the mounting base; The output shaft of the second motor extends through the interior of the mounting base and is fixedly connected to the turntable.

[0009] Preferably, the discharge structure includes a rotating rod, a conical base, a cone head, and a rotating shaft base. The rotating shaft base is fixedly installed inside the discharge pipe on the side near the turntable, and the conical base is fixedly installed on the output shaft of the rotating shaft base. The conical base is conical in shape, and multiple sets of guide grooves are formed on the surface of the conical base; A rotating rod is fixedly installed on the side of the conical base away from the rotating shaft base, and a cone head is fixedly installed on the other end of the rotating rod, and the cone head is cross-shaped.

[0010] Preferably, the two ends of the rotating rod near the conical base and the cone head are fixedly mounted with discs via connecting rods, and an auger is fixedly mounted between the two sets of discs; The middle part of the auger is fixedly connected to the rotating rod by multiple sets of connecting rods; A second set of magnets is fixedly installed inside the conical base.

[0011] This utility model has at least the following beneficial effects: The discharge system is highly efficient and reliably sealed, ensuring continuous production and material purity. The discharge structure employs a synergistic design of crushing, guiding, and conveying. The cross-shaped cone head, rotating with the rotating rod, crushes clumps of praseodymium oxide, preventing blockage at the discharge port. The conical base and guide grooves guide the orderly flow of material, preventing accumulation inside the pipe. Combined with the screw conveyor of the auger, discharge efficiency is improved. Simultaneously, the first and second magnet groups form a magnetically coupled, contactless transmission, eliminating the need for a traditional through-shaft and completely removing the risk of leaking the discharge pipe. This prevents leakage of the extraction medium, environmental pollution, and material loss, while also preventing external impurities from affecting the purity of praseodymium oxide, thus meeting the production requirements of high-purity materials.

[0012] This utility model also has the following beneficial effects: Adjustable discharge speed and low material residue improve raw material utilization: The second motor independently drives the discharge system, which can flexibly adjust the speed according to the viscosity of praseodymium oxide and neodymium materials to ensure stable discharge of materials in different states and avoid speed fluctuations and blockages caused by a single power source; the auger and two sets of discs work together to form a stable spiral conveyor, solving the problem of uneven discharge by traditional gravity and ensuring continuous feeding in subsequent processes. In addition, the auger spiral structure reduces friction between the material and the inner wall of the discharge pipe, reduces material residue, improves raw material utilization, and reduces production cost waste.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] Reference Figure 1-5 An extraction apparatus for praseodymium-neodymium oxide includes a stirring tank 1, with a support fixedly mounted at the bottom end of the stirring tank 1, and further includes: A first motor 3 is fixedly installed at the top of the mixing drum 1, and the output shaft of the first motor 3 extends through into the interior of the mixing drum 1 and is fixedly installed with a stirring rod 4. A discharge pipe 2 is fixedly installed on one side of the bottom end of the mixing drum 1, and a discharge structure is rotatably installed inside the discharge pipe 2.

[0018] Furthermore, three sets of equally spaced arc-shaped stirring blades 5 are fixedly installed on the stirring rod 4, and three sets of stirring blades 6 are fixedly installed at the bottom end of the stirring rod 4. A turntable is fixedly installed on the side of the stirring rod 4 near the stirring blade 6, and the other ends of the three sets of stirring blades 6 are fixedly connected to the turntable. The other ends of the three sets of arc-shaped stirring blades 5 are fixedly installed together with the turntable. The three sets of equidistant arc-shaped stirring blades 5 can form a multi-layer transverse stirring area in the stirring drum 1, expanding the contact area with the praseodymium oxide raw material and extractant, avoiding the "stirring dead corner" that exists in traditional single-layer stirring, and ensuring that the raw material and extractant react fully. On the other hand, the fixed connection between the three sets of stirring blades 6 at the bottom and the turntable not only enhances the structural stability of the stirring blades 6, but also drives the stirring blades 6 to form a longitudinal stirring force through the synchronous rotation of the turntable. Combined with the transverse stirring of the arc-shaped stirring blades 5, a "three-dimensional stirring system" is formed, which further improves the mixing efficiency. In addition, the uniform fixation of the two sets of stirring blades by the turntable can also reduce the uneven force on the stirring rod 4, extend the service life of the device, and adapt to the process requirements of praseodymium oxide extraction that requires long-term continuous stirring.

[0019] Furthermore, a mounting base 7 is fixedly installed on one side of the top end of the discharge pipe 2, and a turntable 9 is rotatably installed inside the mounting base 7; The turntable 9 has a first magnet assembly 10 fixedly installed inside. The fixed installation method of the mounting base 7 can stably support the turntable 9 and the first magnet assembly 10, avoiding the transmission structure from shifting due to device vibration. Secondly, the rotation design of the turntable 9 can drive the first magnet assembly 10 to rotate synchronously, providing power to the subsequent discharge structure through the principle of magnetic coupling, eliminating the need for the through shaft of traditional mechanical transmission, and fundamentally reducing the sealing risks of the discharge pipe 2. Finally, the built-in installation of the first magnet assembly 10 can protect the magnets from corrosion by the extraction medium, extend the service life of the transmission components, and ensure the stable operation of the discharge stage during the praseodymium-neodymium oxide extraction process.

[0020] Furthermore, a second motor 8 is fixedly installed on the top of the mounting base 7; The output shaft of the second motor 8 extends through the interior of the mounting base 7 and is fixedly connected to the turntable 9. The independent setting of the second motor 8 enables independent control of the power for stirring and discharging, avoiding speed fluctuations caused by excessive load on a single motor. This ensures the uniformity of the stirring process and allows for flexible adjustment of the discharging speed according to the viscosity of the praseodymium-neodymium oxide material. On the other hand, the direct fixed connection between the motor output shaft and the turntable 9 reduces intermediate power transmission losses, ensuring stable speed of the first magnet group 10 driven by the turntable 9. This, in turn, ensures the consistency of the subsequent discharging structure and avoids discharging blockage or fluctuations in discharging volume due to unstable power. This meets the process requirements of continuous and uniform discharging of materials after praseodymium-neodymium oxide extraction.

[0021] Furthermore, the discharge structure includes a rotating rod 11, a conical base 12, a cone head 13, and a rotating shaft base 15. The rotating shaft base 15 is fixedly installed inside the discharge pipe 2 on the side near the turntable 9, and the conical base 12 is fixedly installed on the output shaft of the rotating shaft base 15. The conical base 12 is conical, and multiple sets of guide grooves are formed on the surface of the conical base 12. A rotating rod 11 is fixedly installed on the side of the conical base 12 away from the rotating shaft base 15, and a cone head 13 is fixedly installed on the other end of the rotating rod 11. The cone head 13 is cross-shaped. The conical structure and surface guide groove of the conical base 12 can guide the material to flow orderly along the conical surface and guide groove, avoiding the accumulation of material inside the discharge pipe 2. Secondly, the cross-shaped cone head 13 can break up the praseodymium oxide material that may clump during rotation, preventing the blockage of the discharge port by lumpy material. At the same time, the cross-shaped structure can reduce the material flow resistance and increase the discharge speed. Finally, the fixing of the conical base 12 by the rotating shaft base 15 ensures the stability of the discharge structure when rotating at high speed, avoids the discharge obstruction caused by component misalignment, and improves the overall discharge reliability and efficiency of the device, meeting the requirement of rapid separation of materials after praseodymium oxide extraction.

[0022] Furthermore, the rotating rod 11 is fixedly mounted with discs at both ends near the conical base 12 and the cone head 13 via connecting rods, and an auger 16 is fixedly mounted between the two sets of discs; The middle part of the auger 16 is fixedly connected to the rotating rod 11 by multiple sets of connecting rods; The conical base 12 has a second magnet assembly 14 fixedly installed inside. The auger 16 and the two sets of discs work together to continuously and evenly push the material towards the discharge port through the spiral conveying action, avoiding the unevenness of traditional gravity discharge. At the same time, the spiral structure of the auger 16 can reduce the friction between the material and the inner wall of the discharge pipe 2, reducing the material residue rate. Secondly, the auger 16 is fixed to the rotating rod 11 through multiple sets of connecting rods in the middle, which greatly improves the structural strength of the auger 16, prevents the auger from deforming during high-speed conveying, and extends the service life of the components. Thirdly, the second magnet assembly 14 works with the first magnet assembly 10 to achieve "magnetic coupling transmission", which can drive the rotating rod 11 and the auger 16 to rotate without mechanical contact, completely eliminating the leakage risk of traditional mechanical seals, preventing the extraction medium from leaking and polluting the environment or causing material loss, and preventing external impurities from entering the discharge pipe 2 and affecting the purity of praseodymium-neodymium oxide products, significantly improving the environmental friendliness of the device and the stability of product quality.

[0023] In summary: When the device is started, the first motor 3 is activated, and its output shaft drives the stirring rod 4 to rotate at high speed inside the stirring drum 1. As the stirring rod 4 rotates, it synchronously drives the turntable fixed to it to rotate. The three sets of equidistantly distributed arc-shaped stirring blades 5 and the three sets of bottom stirring blades 6 are fixedly connected to the turntable and move synchronously with it. The arc-shaped stirring blades 5 form a multi-layered transverse stirring zone during rotation, which transversely cuts and mixes the praseodymium oxide raw material and extractant in the stirring drum 1. The bottom stirring blades 6 generate longitudinal stirring force, forming a "three-dimensional stirring system" with the transverse stirring of the arc-shaped stirring blades 5. The two work together to eliminate stirring dead zones, ensuring that the raw material and extractant react fully and achieve a highly efficient mixing effect. At the same time, the turntable uniformly fixes the two sets of stirring blades, reducing the uneven force on the stirring rod 4 and ensuring a stable and continuous stirring process. When the stirring is completed and the material needs to be discharged, the second motor 8 is activated, and its output shaft directly drives the turntable 9 inside the mounting base 7 to rotate. The turntable 9 synchronously drives the first set of magnets 10 fixed inside to rotate. Due to magnetic coupling, the rotation of the first magnet group 10 drives the second magnet group 14 inside the conical base 12 in the discharge pipe 2 to rotate synchronously, thereby driving the conical base 12, rotating rod 11, cone head 13, and auger 16 to rotate as a whole. This process achieves contactless transmission through magnetic coupling, avoiding the leakage risks of traditional mechanical transmission. During the linkage process of the discharge structure: when the conical base 12 rotates, its conical surface and multiple sets of guide grooves guide the material to flow orderly along the conical surface, preventing the material from accumulating in the discharge pipe 2; the cross-shaped cone head 13 rotates with the rotating rod 11, preventing the material from accumulating in the discharge pipe 2. The praseodymium-neodymium oxide material is crushed to prevent blockage of the discharge port and reduce material flow resistance. The auger 16 between the two discs rotates synchronously with the rotating rod 11, and pushes the material continuously and evenly to the discharge port through the spiral conveying action, solving the problem of uneven discharge in traditional gravity discharge. The auger 16 is fixed to the rotating rod 11 through multiple sets of connecting rods in the middle to ensure structural stability and no deformation during high-speed conveying. In addition, the fixed support of the rotating shaft base 15 to the conical base 12 ensures the stability of the entire discharge structure during rotation and avoids poor discharge caused by component misalignment.
