Description

Technical Field

[0001] This utility model relates to the technical field of rare earth electrolysis, and in particular to a conductive platform structure for a rare earth electrolysis furnace. Background Technology

[0002] Currently, most rare earth metals are produced by molten salt electrolysis. Industrially, rare earth metals are mainly produced by molten salt electrolysis using a chloride system. This involves electrolysis using dehydrated rare earth chloride materials, where rare earth ions in the rare earth molten salt electrolyte gain electrons at the cathode of the electrolytic cell and are reduced to metals.

[0003] Rare earth electrolysis furnaces are the main equipment used in rare earth metal electrolysis. Since the electrolysis process is carried out at a high current density, the cathode used for electrolysis needs to be able to carry a large current. The cathode is generally large in size and heavy in weight.

[0004] Chinese utility model patent CN217324352U discloses a rare earth electrolysis cathode connection device, belonging to the field of electrolysis equipment. It consists of a first copper busbar 1, a second copper busbar 2, and a cathode rod 3. The upper part of the cathode rod 3 is embedded in a groove 5 and welded to the second copper busbar 2. Bolts are used to fix the cathode rod 3 to the second copper busbar 2 through a third hole 7 and a second hole 6. The second copper busbar 2 is connected to the first copper busbar 1 by bolts passing through a through hole 4. The second copper busbar 2 is a flat rectangular parallelepiped, reducing the risk of cooling medium splashing into the furnace and causing an explosion, effectively reducing the tank voltage by 0.5-0.8V, and saving approximately 8% of electricity. After electrolysis for a period of time, the cathode rod 3 is disassembled and its lower part is ground. Then, the lower part of the cathode rod 3 is embedded in the groove 5 and welded to the second copper busbar 2. Bolts are used to fix the cathode rod 3 to the second copper busbar 2 through the third hole 7 and a second hole 6. The cathode rod 3 can then be turned around and reused. The service life of the cathode rod is increased by approximately 30%, and the unit product cost is reduced by approximately 5%.

[0005] However, in this rare earth electrolysis equipment, copper busbars are welded together and between copper busbars and cathode rods. In other words, large copper or iron plates are used for conduction throughout the process. The conductive material has high resistance, resulting in severe losses during conduction, which is not conducive to the full utilization of power resources. Utility Model Content

[0006] A conductive platform structure for a rare earth electrolysis furnace.

[0007] A furnace cover plate, wherein an insertion hole is provided in the center of the furnace cover plate;

[0008] Multiple anode conductive components are used to mount the anode plate. The anode conductive components are arranged in a circle around the outer ring of the insertion hole and extend above the insertion hole.

[0009] A conductive box, connected to a conductive copper busbar, is used to draw power from an external circuit.

[0010] The upper surface of the conductive box is provided with a copper contact plate that is electrically connected to the conductive copper busbar, and the copper contact plate is located below the anode conductive component and is connected to the anode conductive component by a copper wire.

[0011] By adopting the above technical solution, the conductive copper busbar and the anode conductive component are fixedly installed on the conductive box and the furnace cover plate, respectively. The conductive copper busbar and the anode conductive component are connected by copper wire. Compared with the direct welding between the copper busbar and the iron plate, the connection with copper wire greatly reduces the resistance in the circuit, thereby reducing the power loss during the conduction process and saving power resources.

[0012] A further provision of the above technical solution is that the lower end of the power-connecting copper plate extends into the conductive box, and two adjacent power-connecting copper plates are electrically connected within the conductive box via connecting copper busbars.

[0013] A further provision of the above technical solution is that: a clearance hole is provided on the top surface of the conductive box for the copper plate to extend out, an insulating seat is provided in the clearance hole, and the copper plate is clamped in the clearance hole by the insulating seat.

[0014] By adopting the above technical solution, a strip-shaped clearance hole is opened on the top surface of the conductive base, and an insulating seat is installed in the clearance hole. The insulating seat is interference-fitted with the copper plate and the inner wall of the clearance hole to fix the copper plate and the clearance hole, thereby fixing the copper plate and the top surface of the conductive base.

[0015] A further provision of the above technical solution is that the anode conductive component includes a mounting base and a junction plate, the mounting base extends above the insertion hole for mounting the anode plate; the junction plate extends outward to the outside of the furnace cover plate, and its outer end is bent downward to form a wiring portion.

[0016] By adopting the above technical solution, the inner side of the electrical contact plate contacts the mounting base, enabling it to form an electrical connection. The outer end extends to the outside of the furnace cover plate and bends downward along the edge of the furnace cover plate, so that its end is as close as possible to the electrical contact copper plate below, and can be connected to the electrical contact copper plate by copper wire.

[0017] A further configuration of the above technical solution is that the outer end of the mounting base and the inner end of the power contact plate are superimposed and fixed by the same fixing component.

[0018] A further provision of the above technical solution is that the furnace cover plate is fixedly supported above the conductive box by a support pin.

[0019] A further configuration of the above technical solution is as follows: the conductive copper busbar includes a positive copper busbar and a negative copper busbar, the positive copper busbar is connected to the connecting copper busbar inside the conductive box; the negative copper busbar extends through the conductive box and out to the top of the conductive box.

[0020] A further provision of the above technical solution is that the center of the conductive box is provided with an insertion groove coaxial with the insertion hole for inserting the furnace body of the electrolytic furnace.

[0021] By adopting the above technical solution, the furnace body of the electrolytic furnace is equipped with a heat preservation structure to prevent heat loss from the electrolytic cell. The annular electrical connection slot surrounds the furnace body, saving space for the entire equipment. At the same time, the heat inside the furnace body cannot be transferred to the electrical connection slot in large quantities, ensuring electrical safety and environmental stability within the electrical connection slot.

[0023] 1. The conductive copper busbar and the anode conductive component are fixedly installed on the conductive box and the furnace cover plate, respectively. The conductive copper busbar and the anode conductive component are connected by copper wire. Compared with the direct welding between the copper busbar and the iron plate, the connection of copper wire greatly reduces the resistance in the circuit, thereby reducing the power loss during the conduction process and saving power resources.

[0024] 2. A strip-shaped clearance hole is provided on the top surface of the conductive base. An insulating seat is installed in the clearance hole. The insulating seat is interference-fitted with the copper plate and the inner wall of the clearance hole to fix the copper plate and the clearance hole, thereby fixing the top surface of the copper plate and the conductive base.

[0034] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0035] like Figure 1-5 As shown in the figure, this embodiment discloses a conductive platform structure for a rare earth electrolysis furnace.

[0036] A conductive platform structure for a rare earth electrolysis furnace.

[0037] A furnace cover plate 500, wherein an insertion hole 501 is provided in the center of the furnace cover plate 500;

[0038] Multiple anode conductive components 600 are used to mount the anode plate 4. The anode conductive components 600 are arranged in a circle around the outer ring of the insertion hole 501 and extend above the insertion hole 501.

[0039] The conductive box 800 is connected to a conductive copper busbar for drawing power from an external circuit.

[0040] The conductive box 800 has a power receiving copper plate 7 on its upper surface that is electrically connected to the conductive copper busbar, and the power receiving copper plate 7 is located below the anode conductive component 600 and is connected to the anode conductive component 600 by a copper wire.

[0041] The above is the basic scheme of this embodiment.

[0042] Specific reference Figure 1 and Figure 2 As shown, in this embodiment, the furnace cover plate 500 is located above the conductive box 800, the anode conductive component 600 is located on the furnace cover plate 500, and an anode plate 4 is installed thereon, the anode plate 4 extending into the electrolytic cell of the electrolytic furnace.

[0043] The conductive box 800 is equipped with conductive copper busbars, including a positive copper busbar 8 and a negative copper busbar 9. The positive copper busbar 8 is electrically connected to the anode conductive component 600, and the negative copper busbar 9 is electrically connected to the cathode rod at the center of the electrolytic cell.

[0044] In this embodiment, the conductive copper busbar and the anode conductive component 600 are respectively fixedly mounted on the conductive box 800 and the furnace cover plate 500, and the conductive copper busbar and the anode conductive component 600 are connected by copper wire. Compared with the direct welding between the copper busbar and the iron plate, the connection of copper wire greatly reduces the resistance in the circuit, thereby reducing the power loss during the conduction process and saving power resources.

[0045] In this embodiment, the number and position of the copper contact plates 7 are the same as those of the anode conductive component 600.

[0046] In this embodiment, in order to fix the power-connecting copper plate 7 and prevent it from shifting during use and causing the connection between it and the copper wire to break, the lower end of the power-connecting copper plate 7 extends into the conductive box 800, and two adjacent power-connecting copper plates 7 are electrically connected in the conductive box 800 through the connecting copper busbar 11.

[0047] Specifically, in this embodiment, the junction box is a shell structure with an annular opening at the lower end, extending into the interior of the junction box to form an annular junction groove, as detailed below. Figure 3 As shown, the connecting copper busbar 11 is disposed in the power receiving groove and arranged along the power receiving groove, and the lower end of the power receiving copper plate 7 is fixed to the connecting copper busbar 11.

[0048] To further ensure the stability of the fixation, in this embodiment, the furnace cover plate 500 is fixedly supported above the conductive box 800 by the support pin 10, so that the furnace cover plate 500 and the conductive box 800 form a fixed whole, thereby making the anode conductive component 600 on the furnace cover plate 500 and the power receiving copper plate 7 on the conductive box 800 in a relatively stable position.

[0049] The connecting copper busbar 11 is fixed to the inner wall of the electrical box through a fixing structure inside the electrical box. At the same time, the lower end of the electrical copper plate 7 is fixed to the connecting copper busbar 11, so that the electrical copper plate 7 can be fixed relative to the electrical box.

[0050] Furthermore, the top surface of the conductive box 800 is provided with a clearance hole for the copper plate 7 to extend out, and an insulating seat 12 is provided in the clearance hole. The copper plate 7 is clamped in the clearance hole by the insulating seat 12.

[0051] A strip-shaped clearance hole is provided on the top surface of the conductive base. This clearance hole can accommodate the protruding copper plate 7, and a gap is left between the clearance hole and the copper plate 7. The insulating base 12 has a ring structure with a through hole in the center that is interference-fitted with the copper plate 7. At the same time, the outer wall of the insulating base 12 is interference-fitted with the strip-shaped groove to fix the copper plate 7 and the clearance hole, thereby fixing the copper plate 7 and the top surface of the conductive base. See the specific reference. Figure 4 As shown.

[0052] In this embodiment, the anode conductive component 600 includes a mounting base 610 and a junction plate 620. The mounting base 610 extends above the insertion hole 501 and is used to install the anode plate 4. The junction plate 620 extends outward to the outside of the furnace cover plate 500, and its outer end is bent downward to form a wiring portion 621.

[0053] Specific reference Figure 5As shown, the mounting base 610 is an iron block, and the electrode plate 620 is a copper plate. The inner end of the mounting base 610 extends above the insertion hole 501 so that the anode plate 4 installed at the end can be inserted into the electrolytic furnace through the insertion hole 501 to form an electrolytic cell. The inner side of the electrode plate 620 contacts the mounting base 610 so that it can form an electrical connection. The outer end extends to the outside of the furnace cover plate 500 and bends downward along the edge of the furnace cover plate 500 so that its end is as close as possible to the electrode plate 7 below, and can be connected to the electrode plate 7 by a copper wire.

[0054] Preferably, in this embodiment, the outer end of the mounting base 610 and the inner end of the power contact plate 620 are superimposed and fixed by the same fixing component 630.

[0055] During electrolysis, the iron in the mounting base 610 is consumed, causing wear and tear on the mounting base 610. After a period of use, the mounting base 610 needs to be replaced, or the anode conductive component 600 needs to be disassembled and the anode plate 4 replaced. Compared with welding connection, in this embodiment, the mounting base 610 and the electrode plate 620 are connected by the fixing component 630, which facilitates the disassembly and replacement of the mounting base 610 and saves the material of the electrode plate 620.

[0056] In this embodiment, the positive electrode copper busbar 8 is connected to the connecting copper busbar 11 inside the conductive box 800; the negative electrode copper busbar 9 extends through the conductive box 800 to the top of the conductive box 800 and is used to connect to the cathode plate in the external cathode device.

[0057] In addition, in this embodiment, the center of the conductive box 800 is provided with an insertion groove coaxial with the insertion hole 501 for inserting the furnace body of the electrolysis furnace.

[0058] The electrolytic furnace body is equipped with a heat insulation structure to prevent heat loss from the electrolytic cell. The annular electrical connection slot surrounds the furnace body, saving space for the entire equipment. At the same time, the heat inside the furnace body cannot be transferred to the electrical connection slot in large quantities, ensuring electrical safety and environmental stability within the electrical connection slot.

[0059] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
