Description

Technical Field

[0001] This utility model relates to the field of electrolytic furnace technology, and in particular to a special anode hanger for rare earth metal electrolytic furnaces. Background Technology

[0002] In the field of rare earth metal electrolytic production, the mainstream approach currently uses a rare earth fluoride molten salt system as the electrolyte, with graphite constructing the electrolytic cell and anode plate, and tungsten rods as the cathode. Rare earth metals are extracted through an electrolytic reaction. The core process principle is as follows: rare earth oxides (REO) are added to a molten rare earth fluoride (REF3, LiF) system, causing both to dissociate into rare earth ions (REO). 3+ ), fluoride ions (F-) and oxygen ions (O-) 2 -); Under the influence of an electric field, RE 3+ Rare earth metals (REs) migrate towards the cathode and gain electrons, with F- and O- reacting. 2 The electrons migrate towards the anode and lose electrons to generate F2 and O2. O2 reacts with the graphite anode at around 1000℃ to generate CO2. This process exhibits significant thermal dynamics. The start-up phase is primarily endothermic (requiring the melting of molten salt), while steady-state operation may show net exothermic activity due to Joule heating and reaction heat. Therefore, efficient thermal management is necessary to maintain system temperature stability; otherwise, abnormal electrolyte decomposition, equipment damage, and impact on production efficiency and product quality are likely.

[0003] However, the panels and their supporting fixtures currently widely used in the industry have revealed many technical defects in practical applications, which have become a key bottleneck restricting the improvement of rare earth electrolysis production efficiency. The specific problems are as follows:

[0004] Firstly, insufficient heat dissipation performance restricts the efficiency of the electrolytic reaction. The structural design of traditional panels results in a small heat dissipation area and poor heat dissipation effect, which cannot effectively cope with the thermal dynamic changes during the electrolysis process. It is difficult to quickly assist the melting of molten salt during the start-up phase, and it is also difficult to remove excess heat in time during steady-state operation. As a result, it is difficult to control the heat absorption and exothermic balance of the electrolytic reaction, the reaction rate is limited, and the precipitation efficiency of rare earth metals is directly affected.

[0005] Secondly, material loss is high, resulting in poor production economics. The structural design of traditional panel mounting brackets is unreasonable, which easily leads to materials (such as molten electrolytes, rare earth oxides, etc.) solidifying and adhering to the wall at the handle during electrolysis. This not only causes a large amount of material waste but also increases the difficulty of subsequent material recycling and raises the cost of raw materials for production. At the same time, material adhering to the wall will also pollute the production site, reduce the cleanliness of the site, and increase the workload of cleaning and maintenance.

[0006] Third, the structure is complex, the overall cost is high, and the load-bearing capacity is weak. Traditional supporting fixtures are large in size and complex in structure, which not only increases the difficulty and cost of casting and manufacturing, but also the unreasonable design of their stress structure leads to limited load-bearing capacity. Long-term use is prone to deformation and breakage, requiring frequent replacement and maintenance, which further increases equipment operation and maintenance costs and production downtime.

[0007] Fourth, the panel has poor flatness, making cleaning and maintenance difficult. The structural characteristics of traditional panels result in insufficient surface flatness, making it easy for material residues and dirt to accumulate during use. Cleaning and maintenance are cumbersome and time-consuming, which not only affects the heat dissipation performance and service life of the panel, but may also affect the purity of subsequent electrolytic reactions due to incomplete cleaning, indirectly reducing the quality of rare earth metal products.

[0008] In response to the existing panels and their technical pain points, the industry needs to develop an alternative solution that can take into account efficient heat dissipation, low material loss, low energy consumption, simple structure and easy maintenance, so as to meet the actual needs of increasing production capacity, reducing costs and optimizing on-site management in rare earth electrolysis production. Based on this, this application proposes a fully water-permeable panel and its matching anode mounting bracket to solve the above problems.

[0009] Furthermore, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the applicant studied a large number of documents and patents when making this utility model, but due to space limitations, not all details and contents were listed in detail. However, this does not mean that this utility model does not have the features of these prior art. On the contrary, this utility model has all the features of the prior art, and the applicant reserves the right to add relevant prior art to the background art. Utility Model Content

Detailed Implementation

[0028] The following is a detailed explanation with reference to the accompanying drawings.

[0029] Example 1

[0030] This utility model provides a special anode hanger for rare earth metal electrolysis furnaces. For example... Figure 1 and Figure 2 As shown, the anode mount 100 is connected to the fully circulated water panel 200 of the rare earth metal electrolysis furnace for circulating cooling water to fix the anode of the electrolysis furnace. The electrolysis furnace includes a furnace body 300 with a vertically open upper end and a hollow internal structure. The fully circulated water panel 200 is located vertically above the furnace body 300. The anode mount 100 is detachably mounted on the fully circulated water panel 200 and extends into the furnace body 300. Figure 5 and Figure 6As shown, the anode hanger 100 includes a locking handle 101 and a hanger part 102 fixedly connected to the locking handle 101. The hanger part 102 is fixed to the end of the locking handle 101 near the furnace body 300. The design of the anode hanger 100 connecting and fixing the anode to the fully circulated water panel 200 achieves stable installation of the anode within the electrolysis furnace, ensuring accurate anode positioning during electrolysis and preventing anode movement from affecting the stability of the electrolysis reaction, thus guaranteeing the efficiency and quality of rare earth metal precipitation. Furthermore, the fully circulated water panel 200, located vertically above the furnace body 300, allows for rapid removal of heat generated during furnace operation via internal circulating cooling water, effectively controlling the furnace temperature and preventing abnormal electrolyte decomposition or equipment damage due to localized overheating. Additionally, the detachable design of the anode hanger 100 facilitates subsequent anode replacement, hanger maintenance, and cleaning, reducing equipment downtime and improving production efficiency.

[0031] According to a preferred embodiment, the mounting bracket 102 is provided with a plurality of mounting holes 103. The plurality of mounting holes 103 are symmetrically arranged with the extension direction of the locking handle 101 as the axis. Mounting holes 103 are also provided on the extension axis of the locking handle 101. The plurality of mounting holes 103 on the mounting bracket 102 of this invention are symmetrically arranged with the extension direction of the locking handle 101 as the axis, and mounting holes are also provided on the extension axis. This symmetrical layout ensures that after the anode is installed through the mounting holes, the force is evenly distributed on the mounting bracket 102, avoiding excessive local force that could cause deformation or breakage of the mounting bracket, and extending the service life of the mounting bracket. At the same time, the symmetrical structure ensures that the anode is in a central position within the furnace body 300, maintaining a reasonable distance from the cathode, ensuring a uniform electric field distribution, reducing the situation of excessively high local current density during electrolysis, reducing energy loss, and improving the uniformity of rare earth metal precipitation.

[0032] According to a preferred embodiment, the locking handle 101 near the furnace body 300 and the hanging part 102 near the furnace body 300 are both designed with the same arc shape. A plurality of hanging holes 103 are evenly arranged along the arc shape, and the anode 301 is connected to each of the hanging holes 103 by bolts. The arc design adapts to the internal space structure of the furnace body 300, making the hanging part 102 and the anode 301 fit the shape of the furnace body more closely, reducing the space occupied by the hanging part within the furnace, and providing a more sufficient reaction area for the electrolytic reaction. The bolt connection not only securely fixes the anode 301 to the hanging part 102, preventing the anode from falling off during electrolysis, but also facilitates the disassembly and fine-tuning of the anode's position. Furthermore, the evenly arranged hanging holes along the arc shape allow for flexible selection of the installation position according to the anode size and electrolysis requirements, improving the versatility of the hanging part.

[0033] According to a preferred embodiment, the locking handle 101 has an arc-shaped contraction section 104 at one end near the hanging part 102, which facilitates the uniform arrangement of several hanging holes 103 along an arc. The width of the arc-shaped contraction section 104 is smaller than the width of the locking handle 101. On the one hand, this provides sufficient space for the hanging holes 103 to be arranged uniformly along an arc, avoiding the situation where the spacing between the hanging holes is too small due to the excessive width of the locking handle, and ensuring sufficient reaction gap after the anode is installed; on the other hand, the contraction structure can reduce the amount of material used in this part of the hanging device, reduce the overall weight of the hanging device while ensuring its strength, facilitate the handling and installation of the hanging device, and at the same time reduce the load on the full-flow panel 200, thereby improving the overall stability of the equipment.

[0034] According to a preferred embodiment, a plurality of hanging ears 209 are provided on the full-flow water panel 200. The plurality of hanging ears 209 are symmetrically arranged about the central axis of the full-flow water panel 200. The symmetrical arrangement of the hanging ears 209 on the full-flow water panel 200 about the central axis of the panel provides uniform force points for the installation of the full-flow water panel 200, so that the panel is subjected to balanced force during the fixing process, avoiding panel deformation due to uneven installation force, ensuring the sealing fit between the panel and the furnace body 300, and preventing the leakage of high-temperature gas inside the furnace; at the same time, the hanging ear structure facilitates the connection and fixing of the panel with other equipment components, simplifies the installation process, improves equipment assembly efficiency, and the symmetrical design makes the panel more convenient for subsequent maintenance and disassembly, reducing the difficulty of operation.

[0035] According to a preferred embodiment, such as Figure 3 and Figure 4 As shown, the hollow, fully ventilated water panel 200 has an inlet pipe 201, an outlet pipe 202, and a first baffle bar 203 connected inside. The first baffle bar 203 connects between the inlet pipe 201 and the outlet pipe 202, and its other end connects to the furnace opening 302 of the furnace body 300 located at the center of the fully ventilated water panel 200. The fully ventilated water panel 200 also has a second baffle bar 204 and a fifth baffle bar 208 inside. The second baffle bar 204 surrounds the furnace opening 302 to form a furnace opening ring. The fifth baffle bar 208 is arranged along the outer contour of the fully ventilated water panel 200. The combination of the inlet pipe 201, outlet pipe 202, and first baffle strip 203 inside the fully ventilated panel 200 separates the inlet and outlet pipes and connects to the furnace opening 302, forming an orderly water flow channel. This ensures that after the cooling water enters from the inlet pipe, it can flow fully through all areas of the panel along the channel, avoiding dead zones and improving the overall heat dissipation efficiency of the panel. The second baffle strip 204 surrounds the furnace opening 302 to form a furnace opening ring, which can prevent cooling water from flowing directly into the high-temperature area of ​​the furnace opening, protecting the edge structure of the furnace opening and preventing damage to the panel. The fifth baffle strip 208 is set along the outer contour of the panel, which can restrict the flow of cooling water inside the panel, preventing cooling water from leaking from the edge of the panel and ensuring the sealing and stability of the cooling system.

[0036] According to a preferred embodiment, the first water-blocking strip 203 separates the inlet pipe 201 and the outlet pipe 202 to form an annular flow channel from the inlet pipe 201 to the outlet pipe 202 with the furnace opening 302. The annular flow channel causes the cooling water to flow in an annular pattern inside the panel, increasing the contact time and contact area between the cooling water and the panel, improving heat exchange efficiency, and enabling the panel to remove the heat absorbed by the furnace body more quickly and evenly, effectively controlling the operating temperature of the electrolytic furnace. At the same time, the annular flow channel structure stabilizes the water flow speed, avoiding uneven heat dissipation caused by excessively fast or slow local water flow, ensuring consistent temperature in all areas of the panel, preventing thermal stress caused by excessive temperature differences in the panel, and extending the service life of the panel.

[0037] According to a preferred embodiment, a third water-blocking strip 205 is further provided within the fully ventilated panel 200. The third water-blocking strip 205 is arranged around the second water-blocking strip 204, and the two ends of the third water-blocking strip 205 located on both sides of the first water-blocking strip 203 are respectively separated from the first water-blocking strip 203 by water passage intervals 207. This design further divides the internal space of the panel, causing the cooling water to be diverted during flow, increasing the water flow path length, and improving the adequacy of heat exchange; the water passage intervals 207 ensure that the cooling water can flow smoothly between different areas, avoiding water flow blockage, and at the same time, the diverted cooling water can act more precisely on different heat-generating areas of the panel, providing targeted heat dissipation, further optimizing the panel temperature control effect, and ensuring the stable operation of the electrolytic furnace.

[0038] According to a preferred embodiment, a fourth water-blocking strip 206 is further provided inside the fully ventilated panel 200. The fourth water-blocking strip 206 is positioned between the second water-blocking strip 204 and the third water-blocking strip 205 to isolate a water passage within the space formed by the second water-blocking strip 204 and the third water-blocking strip 205. By isolating an independent water passage within the space formed by the second water-blocking strip 204 (forming a furnace opening ring around the furnace opening 302) and the third water-blocking strip 205, dead zones in the cooling water flow within the fully ventilated panel 200 can be avoided, allowing the cooling water to evenly cover the area and maximizing the heat dissipation area of ​​the fully ventilated panel 200. The fully ventilated panel 200 of this invention has a large heat dissipation area and excellent heat dissipation effect, further improving heat dissipation uniformity and ensuring a stable match between the rate of heat absorption and the rate of heat generation during the electrolysis reaction. This provides temperature environment support for "accelerating the electrolysis reaction rate" and indirectly contributes to increased production capacity.

[0039] According to a preferred embodiment, the fourth baffle bar 206 is spirally and vertically ascending with the end closest to the inlet pipe 201 as its lowest point and the center of the furnace opening 302 as its axis, so that the end closest to the outlet pipe 202 is set as its highest point. Thus, the fourth baffle bar 206 forms an annular flow channel for cooling water circulation between the second baffle bar 204 and the third baffle bar 205. This annular flow channel is a spirally ascending flow channel from the inlet pipe 201 to the outlet pipe 202. Because the cooling water absorbs heat and its density decreases, it generates upward buoyancy. Combined with the overall circulation of the cooling water, this accelerates the flow rate of the cooled water after heat absorption from the furnace opening 302 (i.e., between the second baffle bar 204 and the third baffle bar 205) to the outlet pipe 202, speeding up the cooling water circulation and effectively improving heat exchange efficiency. This invention utilizes the physical characteristics of cooling water: the cooling water absorbs heat and its density decreases, generating upward buoyancy, which, in conjunction with the upward path of the spiral flow channel, accelerates the flow of the cooled water after heat absorption towards the outlet pipe 202, significantly improving the cooling water circulation efficiency. On the one hand, the faster circulation speed can promptly remove the excess heat generated by the electrolysis reaction (especially the exothermic reaction of CO2 generation at the anode at around 1000℃), accurately maintaining the thermal balance of "endothermic start-up and possible exothermic steady state"; on the other hand, efficient heat exchange reduces additional temperature control energy consumption, avoids local overheating which exacerbates anode loss, indirectly reduces anode unit consumption, and enhances cost reduction and efficiency improvement.

[0040] To further illustrate the structure of this application, the electrolytic furnace is described. Preferably, the furnace body 300 consists of an inner steel sleeve, a middle steel sleeve, and an outer steel sleeve. Insulation material is filled between each pair of the inner, middle, and outer steel sleeves. This serves three purposes: first, it reduces heat loss from the high temperature inside the furnace (approximately 1000°C for electrolysis) to the external environment, lowering energy consumption for heating the molten salt and directly contributing to a reduction in pre-furnace power consumption; second, it protects the external structure of the furnace body 300 and the safety of operators, preventing the external environment from being affected by high temperatures; and third, it maintains a stable furnace temperature, reducing the interference of external temperature fluctuations on reaction steps such as "rare earth oxide (REO) melting and ion migration," providing environmental protection for stable production capacity.

[0041] According to a preferred embodiment, the anode 301 extends into the furnace body 300 from the fully vented panel 200 and the furnace opening 302. The anode 301 can be a graphite anode. This invention uses graphite as the electrolytic cell and anode material, and a tungsten rod as the cathode. The tungsten cathode is resistant to high temperatures and molten salt corrosion, while the graphite anode is suitable for the anode reaction of "O2 reacting with C to generate CO2." Both can precisely contact the molten rare earth fluorides (REF3, LiF) and rare earth oxides (REO) mixed electrolyte, maximizing the reaction area between the electrode and the electrolyte. On one hand, it improves the RE... 3+ Deposition at the cathode, F- / O 2- The efficiency of the anode reaction directly drives the increase in output per furnace; on the other hand, high-quality electrode materials extend the electrode replacement cycle, reduce consumable costs and downtime maintenance time, which meets the goal of cost reduction and efficiency improvement.

[0042] According to a preferred embodiment, a graphite block is further disposed on the inner side of the inner steel sleeve. The graphite block extends vertically at the furnace opening 301 and is fitted with a tungsten crucible with an elliptical bottom. Firstly, the graphite block further enhances the insulation effect of the inner steel sleeve, reduces heat conduction from the furnace to the steel sleeve, lowers heat loss, and protects the inner steel sleeve from high-temperature molten salt corrosion. Secondly, the elliptical bottom of the tungsten crucible increases the molten salt capacity, and the tungsten material is corrosion-resistant and high-temperature resistant, preventing production interruptions caused by crucible damage. Thirdly, it optimizes the relative position of the electrode and the crucible, ensuring efficient electrolysis and helping to extend the lifespan of the electrolytic furnace.
