Description

Technical Field

[0002] An electrolytic furnace is an important industrial piece of equipment, mainly used to produce metals or purify substances through electrolytic reactions. It is widely used in metal smelting, rare earth element extraction and purification, and alloy preparation. A molten salt electrolytic furnace uses molten salt as the electrolyte. A molten salt electrolytic furnace includes a working anode, a working cathode, and a conductive metal wire connected to the working cathode. In the preparation of high-purity / nano-scale refractory metal powders using molten salt electrolysis, a positive potential is applied to the working anode, and the working cathode is connected to a DC power supply via the conductive metal wire, thus providing a negative potential to the working cathode.

[0003] The anode and cathode rods in a molten salt electrolysis furnace need to be raised and lowered within the furnace body. However, the furnace body of a molten salt electrolysis furnace is as high as 4 meters. Currently, the lifting mechanism for the anode or cathode rod in a molten salt electrolysis furnace only has a single-stage transmission. The height of the lifting mechanism needs to reach more than 5.5 meters, which is not easy to install and the required height space is difficult to meet. Utility Model Content

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the present invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0029] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of an electrode lifting device for an electrolytic furnace provided in an embodiment of this application. Figure 2 yes Figure 1 The diagram shows a partial structural schematic of the electrode lifting device of the electrolytic furnace. This electrode lifting device can be integrated into the electrolytic furnace and installed on one side of the furnace body 001. The electrode lifting device can have two sets of lifting components 100. Each set of lifting components 100 may include: a lifting frame 101, a first drive motor 102, a first transmission screw 103, a connecting frame 104, a second drive motor 105, and a second transmission screw 106.

[0030] The first drive motor 102 in the lifting assembly 100 can be mounted on the lifting frame 101, and the output shaft of the first drive motor 102 can be connected to one end of the first transmission screw 103. Here, the axial direction of the first transmission screw 103 can be parallel to the axial direction of the furnace body 001.

[0031] One end of the connecting frame 104 in the lifting assembly 100 can be sleeved on the first transmission screw 103 and connected to the first transmission screw 103 in a transmission connection.

[0032] The second drive motor 105 in the lifting assembly can be installed at the other end of the connecting frame 104, and the output shaft of the second drive motor 105 can be connected to one end of the second transmission screw 106. The second transmission screw 106 is arranged parallel to the first transmission screw 103, and the electrode rod A can be drivenly connected to the second transmission screw 106. Here, the cathode rod 200 can be drivenly connected to the second transmission screw 106 in one set of lifting assemblies 100, and the anode rod 300 can be drivenly connected to the second transmission screw 106 in another set of lifting assemblies 100.

[0033] For example, when the first drive motor 102 is in operation, it can drive the first transmission screw 103 to rotate, so that the connecting frame 104 can move along the axial direction of the first transmission screw 103, allowing the electrode rod to be raised and lowered. When the second drive motor 105 is in operation, it can drive the second transmission screw 106 to rotate, so that the electrode rod can move along the axial direction of the second transmission screw 106, thereby achieving secondary raising and lowering.

[0034] In this embodiment, a primary transmission component is integrated into the electrode lifting device, consisting of a first drive motor 102 and a first transmission screw 103. A secondary transmission component is formed by a second drive motor 105 and a second transmission screw 106, and the secondary transmission component is connected to the electrode rod. A connecting frame 104 connects the primary and secondary transmission components in series. This allows the primary transmission component to drive the secondary transmission component and the electrode rod to rise and fall a certain distance when the electrode rod needs to be lifted or lowered a significant distance. The secondary transmission component then drives the electrode rod to rise and fall a further distance, reducing the overall height of a single transmission component. This effectively improves height limitations, facilitates installation, and increases space utilization. Furthermore, using a drive motor and transmission screw to lift and lower the electrode rod eliminates the need for manual operation during high-temperature feeding of the cathode / anode rods. This ensures safety, saves manpower, and provides more accurate feeding values ​​for the cathode / anode rods within the furnace. Additionally, the two drive motors in the secondary transmission can be replaced with two small stepper motors, reducing equipment assembly costs. In actual operation, the primary transmission allows for rapid feeding and discharging, while the secondary transmission precisely controls the feeding amount.

[0035] In summary, this application provides an electrode lifting device for an electrolytic furnace, which can have two sets of lifting components. A primary transmission component is integrated within the electrode lifting device, consisting of a first drive motor and a first transmission screw. A secondary transmission component is formed by a second drive motor and a second transmission screw, with the secondary transmission component connected to the electrode rod. A connecting frame connects the primary and secondary transmission components in series. Thus, when the electrode rod needs to be lifted a large distance, the primary transmission component drives the secondary transmission component and the electrode rod to lift a certain distance as a whole. The secondary transmission component then drives the electrode rod to lift a certain distance, reducing the overall height of a single transmission component, effectively improving height limitations, facilitating installation, and increasing space utilization. Furthermore, using a drive motor and transmission screw to lift the electrode rod eliminates the need for manual operation when feeding the cathode / anode rods at high temperatures, ensuring safety and saving manpower. The feeding value of the cathode / anode rods within the furnace is also more accurate. Additionally, the two drive motors in the secondary transmission can be replaced with two small stepper motors, reducing equipment assembly costs. In actual operation, the primary transmission allows for rapid feeding and discharging, while the secondary transmission precisely controls the feeding amount.

[0036] For example, such as Figure 2 As shown, the connecting frame 104 may include: a first connecting plate 1041 and a second connecting plate 1042. One end of the first connecting plate 1041 is sleeved on and driven by the first transmission screw 103. The other end of the first connecting plate 1041 may be fixedly connected to the second connecting plate 1042. The second drive motor 105 is mounted on the second connecting plate 1042. The first connecting plate 1041 may be perpendicularly connected to both the first transmission screw 103 and the second transmission screw 106.

[0037] Optional, such as Figure 2 As shown, electrode rod A may include: electrode rod body A1 and mounting block A2. Mounting block A2 can be sleeved on and driven by the second transmission screw 106. One end of electrode rod body A1 can be fixed to mounting block A2 and insulated from it. Thus, electrode rod body A1 can be mounted on mounting block A2. When the second transmission screw 106 rotates, mounting block A2 can move axially along the second transmission screw 106 to achieve the raising and lowering of electrode rod A.

[0038] In the embodiments of this application, please refer to Figure 3 , Figure 3This is a schematic diagram of the structure of another electrode lifting device for an electrolytic furnace provided in an embodiment of this application. The electrode lifting device for the electrolytic furnace may further include: a platform support 400, a first driving component 500, a first transmission mechanism 600, a second driving component 700, and a second transmission mechanism 800. Both the first transmission mechanism 600 and the second transmission mechanism 800 can be mounted on the platform support 400. The first transmission mechanism 600 can be connected to a set of lifting components 100, and the second transmission mechanism 800 can be connected to another set of lifting components 100. The first driving component 500 can be connected to the first transmission mechanism 600, and the second driving component 700 can be connected to the second transmission mechanism 800. The first driving component 500 can be configured to drive a set of lifting components 100 to move in a direction closer to or farther from the furnace body 001 via the first transmission mechanism 600; the second driving component 700 can be configured to drive another set of lifting components 100 to move in a direction closer to or farther from the furnace body 001 via the second transmission mechanism 800.

[0039] For example, when the first drive component 500 is in operation, it drives a set of lifting components 100 to move axially along the first transmission mechanism 600 via the first transmission mechanism 600, thereby causing the second transmission screw 106 and electrode rod A to move in a direction closer to or farther from the furnace body 001. When the second drive component 700 is in operation, it drives another set of lifting components 100 to move axially along the second transmission mechanism 800 via the second transmission mechanism 800, thereby causing the second transmission screw 106 and electrode rod A of the other set of lifting components 100 to move in a direction closer to or farther from the furnace body 001. For example,

[0040] Please refer to the following in this application: Figure 4 , Figure 4 yes Figure 3 The diagram shows a partial structural schematic of the electrode lifting device of the electrolytic furnace. Both the first driving component 500 and the second driving component 700 can be drive motors. Both the first transmission mechanism 600 and the second transmission mechanism 800 can include a drive screw B1 and a slider B2 sleeved on the drive screw B1, with the slider B2 being tractively connected to the drive screw B1. Specifically, the end of the first transmission screw 103 in one set of lifting assemblies 100 can be rotatably connected to the slider B2 in the first transmission mechanism 600, and the first transmission screw 103 in the other set of lifting assemblies 100 can be rotatably connected to the slider B2 in the second transmission mechanism 800. Thus, through the cooperation of the drive motor and the drive screw, the slider B2 is driven to move along the axial direction of the drive screw B1, realizing the horizontal movement of the lifting assembly 100.

[0041] For example, the drive screw B1 in the first transmission mechanism 600 and the drive screw B1 in the second transmission mechanism 800 can be coaxially arranged. It should be noted that in other possible implementations, the drive screw B1 in the first transmission mechanism 600 and the drive screw B1 in the second transmission mechanism 800 can be arranged side by side.

[0042] Optional, such as Figure 4 As shown, the platform support 400 may have two support seats 401 arranged opposite to each other. One end of the drive screw B1 can be rotatably connected to one support seat 401, and the other end of the drive screw B1 can pass through the other support seat 401 and be connected to the output shaft of the drive motor. In this way, by setting the support seat 401 in the platform support, the drive screw B1 can be effectively supported, thereby improving the movement stability of the slider B2 on the drive screw B1.

[0043] For example, the platform support 400 may have two sets of support groups 401 corresponding to the first transmission mechanism 600 and the second transmission mechanism 800, each set of support groups including two support seats 401.

[0044] In this embodiment, the electrode lifting device of the electrolytic furnace may further include a control component (not shown in the figure), which may be electrically connected to the first drive motor 102, the second drive motor 105, and drive motors 500 and 700. For example, the control component may include a PLC control system. After receiving input commands from the user, the control component controls at least one of the first drive motor 102, the second drive motor 105, and drive motors 500 and 700 to be in a working state, thereby driving the corresponding transmission components to move. This improves the automation level and operational safety of the electrode lifting device of the electrolytic furnace.

[0045] In summary, this application provides an electrode lifting device for an electrolytic furnace, which can have two sets of lifting components. A primary transmission component is integrated within the electrode lifting device, consisting of a first drive motor and a first transmission screw. A secondary transmission component is formed by a second drive motor and a second transmission screw, with the secondary transmission component connected to the electrode rod. A connecting frame connects the primary and secondary transmission components in series. Thus, when the electrode rod needs to be lifted a large distance, the primary transmission component drives the secondary transmission component and the electrode rod to lift a certain distance as a whole. The secondary transmission component then drives the electrode rod to lift a certain distance, reducing the overall height of a single transmission component, effectively improving height limitations, facilitating installation, and increasing space utilization. Furthermore, using a drive motor and transmission screw to lift the electrode rod eliminates the need for manual operation when feeding the cathode / anode rods at high temperatures, ensuring safety and saving manpower. The feeding value of the cathode / anode rods within the furnace is also more accurate. Additionally, the two drive motors in the secondary transmission can be replaced with two small stepper motors, reducing equipment assembly costs. In actual operation, the primary transmission allows for rapid feeding and discharging, while the secondary transmission precisely controls the feeding amount.
