Description

Technical Field

[0001] This utility model relates to the field of metal electrolysis furnace technology, specifically to a rare earth metal electrolysis furnace with a stirring function. Background Technology

[0002] Rare earth metals, also known as rare earth elements, are a collective term for 17 elements in Group IIIB of the periodic table, including scandium, yttrium, and the lanthanides, commonly represented by R or RE. From the discovery of the first rare earth element, yttrium, in 1794, to the discovery of the naturally occurring rare earth element, promethium, in 1972, it took 178 years for all 17 rare earth elements to be found in nature. The luster of rare earth metals is between that of silver and iron. Rare earth metals are highly chemically reactive. Electrolytic furnaces are essential for the preparation of rare earth metals; however, in existing electrolytic furnaces, the electrolysis reaction of rare earth metals mostly occurs naturally, resulting in low efficiency and low production rates.

[0003] To address the aforementioned issues, a search revealed an existing patent (application number: CN201821275561.2) for an electrolytic furnace for rare earth metals. The patent describes a furnace comprising an electrolytic vessel, a fixing plate, a connecting rod, and a baffle. The electrolytic vessel has a graphite layer on its outer side, and heat-resistant bricks are installed on the outer side of the steel plate layer. The fixing plate is fixed to the upper end of the electrolytic vessel. The inner wall of the electrolytic vessel has cathode and anode rods. A low-speed motor is installed on top of the heat-resistant bricks. A first gear is connected to a second gear via a belt, and a support rod is installed inside the second gear. The connecting rod is installed at the upper end of the support rod, and a crucible is installed at the lower end of the support rod. A through groove is pre-reserved inside the crucible, and the baffle is installed directly below the crucible. In this rare earth metal electrolytic furnace, the low-speed motor drives the gears and belt to rotate, which in turn drives the support rod to rotate. This allows the connecting rod and crucible to stir the electrolyte solution, significantly increasing the electrolysis speed and accelerating the preparation efficiency of rare earth metals.

[0004] However, when performing rare earth metal electrolysis, the electrolyte can only be stirred continuously in one direction, resulting in low stirring efficiency. This prevents the anode and cathode rods from reaching their maximum effectiveness, leading to excessively long electrolysis times and reduced electrolysis efficiency of rare earth metals. Utility Model Content

[0005] This invention solves the technical problems in the background art mentioned above and provides a rare earth metal electrolysis furnace with a stirring function.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0007] A rare earth metal electrolytic furnace with a stirring function includes:

[0008] An electrolysis tank is used to hold electrolyte for the electrolysis of rare earth metals;

[0009] A stirring assembly, including stirring blades arranged inside an electrolysis tank for stirring the electrolyte;

[0010] The drive assembly includes a mounting bracket that slides on one side of the electrolysis tank to mount the drive assembly;

[0011] The limiting assembly includes a placement slot arranged inside the electrolytic tank for limiting the position of the crucible.

[0012] Preferably, the electrolytic tank is equipped with a crucible for holding rare earth elements, and an anode rod and a cathode rod for auxiliary electrolysis are fixedly connected inside the electrolytic tank. A drain valve for discharging electrolyte is fixedly connected to the bottom side of the electrolytic tank.

[0013] Preferably, the stirring assembly further includes:

[0014] Rotate the gear, which is fixed to the top of the stirring blade;

[0016] A fixed gear is positioned below the mounting plate, passing through it.

[0017] Preferably, the rotating gear is rotatably connected to the bottom of the mounting plate, and the rotating gear meshes with the fixed gear.

[0018] Preferably, the driving component further includes:

[0019] An electric telescopic rod is fixed to one side of the electrolysis tank, with its output end fixed to the mounting frame.

[0020] The drive motor is fixedly mounted on the mounting bracket;

[0021] The first pulley is fixedly connected to the output end of the drive motor;

[0022] The drive belt meshes with the first pulley;

[0025] Preferably, the limiting component further includes a slot fixed to the crucible, the crucible sliding within the placement groove, and the slot fitting onto the placement groove.

[0026] With the above structure, this utility model has the following advantages:

[0027] 1. By arranging a drive assembly and a stirring assembly, the mounting frame can be raised and lowered to facilitate the placement and removal of the crucible.

[0038] The present invention will now be described in further detail with reference to the full text:

[0039] Example 1:

[0040] Combined with appendix Figures 1 to 4 This embodiment provides a rare earth metal electrolysis furnace with a stirring function, including an electrolysis tank 1 for placing electrolyte to electrolyze rare earth metals, a crucible 101 for placing rare earths arranged inside the electrolysis tank 1, an anode rod 102 and a cathode rod 103 for auxiliary electrolysis fixed inside the electrolysis tank 1, and a drain valve 104 for discharging electrolyte fixed to one side bottom of the electrolysis tank 1.

[0041] To ensure the stability of crucible 101 during the electrolysis of rare earth metals, a limiting component is arranged, which includes a placement groove 401 arranged in the electrolysis tank 1 for limiting the position of crucible 101.

[0042] In a preferred embodiment, the limiting component also includes a slot 402 fixed to the crucible 101, the crucible 101 sliding within the placement groove 401, and the slot 402 fitting onto the placement groove 401.

[0043] It should be noted that when the crucible 101 is placed in the placement groove 401, the outer wall of the crucible 101 is attached to the inner wall of the placement groove 401 and the inner wall of the slot 402 is attached to the outer wall of the placement groove 401.

[0044] Example 2:

[0045] Based on Example 1, in order to improve the efficiency and speed of electrolysis, a stirring assembly is arranged. The stirring assembly includes stirring blades 201 arranged in the electrolysis tank 1 for stirring the electrolyte.

[0046] In a preferred embodiment, the stirring assembly further includes: a rotating gear 202 fixed to the top of the stirring blade 201; a mounting plate 203 arranged above the crucible 101; and a fixing gear 204 extending through and arranged below the mounting plate 203.

[0047] In a preferred embodiment, the rotating gear 202 is rotatably connected to the bottom of the mounting plate 203, and the rotating gear 202 meshes with the fixed gear 204.

[0048] It should be noted that the diameter of the fixed gear 204 is larger than the diameter of the placement groove 401, the center point of the fixed gear 204 and the center point of the placement groove 401 are on the same horizontal line, the stirring blade 201 is located outside the crucible 101, and the anode rod 102 and the cathode rod 103 are located at opposite corners inside the electrolysis tank 1.

[0049] Example 3:

[0050] Based on Examples 1 and 2, in order to enable the stirring blade 201 to stir the electrolyte in the electrolysis tank 1 and facilitate the placement of the crucible 101, a driving assembly is arranged. The driving assembly includes a mounting bracket 301 that slides on one side of the electrolysis tank 1 and mounts the driving assembly.

[0051] In a preferred embodiment, the drive assembly further includes: an electric telescopic rod 302, fixedly connected to one side of the electrolysis tank 1 and with its output end fixedly connected to the mounting bracket 301; a drive motor 303, fixedly connected to the mounting bracket 301; a first pulley 304, fixedly connected to the output end of the drive motor 303; a transmission belt 305, meshing with the first pulley 304; and a second pulley 306, fixedly connected to the top of the mounting plate 203.

[0052] In a preferred embodiment, the end of the first pulley 304 away from the drive motor 303 is rotatably connected to the mounting bracket 301, the end of the transmission belt 305 away from the first pulley 304 is engaged with the second pulley 306, the second pulley 306 is rotatably connected to the mounting bracket 301, and the fixed gear 204 passes through the second pulley 306 and is fixed to the mounting bracket 301.

[0053] It should be noted that when the start drive motor 303 is activated, the second pulley 306 drives the mounting plate 203 to rotate via the first pulley 304 and the transmission belt 305, which in turn drives the rotating gear 202 to revolve around the fixed gear 204. Under the action of the fixed gear 204, the rotating gear 202 rotates on its own axis. When the electric telescopic rod 302 pulls the mounting frame 301 to the highest position, the gap between the fixed gear 204 and the electrolysis box 1 is greater than the height of the crucible 101.

[0054] The operating steps are as follows: Electrolyte is injected into the electrolysis tank 1, and then the crucible 101 containing rare earth metals is placed in the placement tank 401. Then, the electric telescopic rod 302 is activated to push the mounting frame 301 down until the stirring blade 201 is inserted into the electrolyte. The drive motor 303 is activated to drive the first pulley 304 to rotate, and through the second pulley 306, it drives the mounting plate 203 to rotate. At this time, the mounting plate 203 drives the rotating gear 202 to revolve around the fixed gear 204. Under the action of the fixed gear 204, the rotating gear 202 rotates on its own axis while revolving, thereby causing the stirring blade 201 to stir the electrolyte in the electrolysis tank 1. After electrolysis is completed, the electric telescopic rod 302 is activated to push the mounting frame 301 up, and the drain valve 104 is opened to drain the excess electrolyte inside. Then, the crucible 101 is removed from the placement tank 401, and the rare earth metals electrolyzed in the magnetic crucible 101 can continue to be processed.

[0055] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
