Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of rare earth electrolysis devices, and in particular to a device for fixing a self-consuming iron cathode in rare earth alloy electrolysis. Background Technology
[0002] Rare earth ferroalloys are special alloys combining rare earth elements and iron. Their production involves a consumable iron cathode process within a fluoride molten salt system. This consumable iron cathode is characterized by the gradual consumption of iron material during electrolysis, which participates in the reaction. Consequently, the iron cathode requires constant manual replacement, a labor-intensive and tedious process. Furthermore, the small contact area between the iron cathode and the fixture results in poor conductivity.
[0003] To address the aforementioned deficiencies, Chinese patent application CN215757675U discloses a rare earth electrolytic iron cathode fixing device, comprising symmetrically arranged clamping plates, a horizontal baffle, a reference plate, and a wedge-shaped pin. The horizontal baffle, the reference plate, and the clamping plates enclose a space for inserting the iron cathode. The iron cathode is inserted into the space, and the pin is inserted between the iron cathode and the horizontal baffle to clamp the iron cathode. A conductive copper busbar is provided on the side of the reference plate near the iron cathode. Each of the symmetrically arranged clamping plates has a corresponding limiting hole. The reference plate and the conductive copper busbar are transversely inserted into the limiting holes. One end of the reference plate extending outward from the space forms a connecting part.
[0004] The device disclosed in the aforementioned patent application increases the conductivity of the device to some extent, but the contact area between the arc-shaped section of the conductive copper busbar and the iron cathode is small, resulting in a negligible conductivity effect. Furthermore, the iron cathode being inserted into a fixed space from above poses a safety risk. Utility Model Content
[0005] The purpose of this invention is to provide a device for fixing a consumable iron cathode in rare earth alloy electrolysis, so as to solve the problems of small contact area and poor conductivity between the consumable iron cathode and the clamp.
[0006] To achieve the above objectives, this utility model provides a rare earth alloy electrolysis self-consuming iron cathode fixing device, including a telescopic connecting plate, a movable buckle, a clamping plate, a pin, and symmetrically arranged fixing bolts. The parallel telescopic connecting plate and the movable buckle form a space for fixing the iron cathode. A handle is provided above the movable buckle. The telescopic connecting plate and the movable buckle have a semi-circular arc structure and are connected to the clamping plate by fixing bolts perpendicular to them. The pin is inserted between the telescopic connecting plate and the clamping plate to clamp the iron cathode. The front end of the telescopic connecting plate is connected to the fixing plate, the adjusting handwheel is connected to the rotating column, and the lifting reducer is fixedly installed on one side of the lifting fixing frame. The lifting fixing frame and the motor are fixed to the ground.
[0007] As an improvement, the telescopic connecting plate and the movable buckle are made of copper, which makes close contact with the iron cathode over a large area.
[0008] As an improvement, a groove is provided below the movable buckle, and the shape and size of the groove match the symmetrically parallel fixed bolts.
[0009] As an improvement, the self-consuming iron cathode is cylindrical, and the telescopic connecting plate and the movable buckle are both provided with a groove with a semi-circular cross-section on the side that is in close contact with the iron cathode. The shape and size of the groove match the shape and size of the iron cathode.
[0010] As an improvement, the pin is a component used to insert between the clamping plate and the telescopic connecting plate, and has a structure that is wider at the top and narrower at the bottom.
[0011] As an improvement, the handle is mounted above the movable latch, making it easier to move the movable latch when installing or removing the iron cathode.
[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. The telescopic connecting plate and the movable buckle are made of copper, and the part that contacts the self-consuming iron cathode has a semi-circular arc groove that matches the shape and size of the iron cathode. This allows for a large-scale, tight fit with the iron cathode, increasing the contact area of the iron cathode by more than 30%, and greatly improving its conductivity. The power consumption per unit product is reduced by 6-10%.
[0013] 2. Because the conductivity of the device is guaranteed, the inner wall of the telescopic connecting plate and the movable buckle that are attached to the iron cathode are not prone to sintering scars, which increases the service life by 50%, thereby reducing the time to replace the iron cathode and reducing the labor intensity of workers.
[0014] 3. The movable buckle and telescopic connecting plate clamp the iron cathode between the two and fix it with a pin. The iron cathode can be quickly disassembled by removing the pin. The operation is simple and convenient, and all operations are carried out on the ground with no safety risks. Attached Figure Description

Preferably, the symmetrically arranged fixing bolts 112 are parallel to each other, and the telescopic connecting plate 3, movable buckle 114, and clamping plate 111 are parallel to each other and perpendicular to the fixing bolts 112. Preferably, the telescopic connecting plate 3 and movable buckle 114 are located parallel to each other on both sides of the iron cathode 2, and each has a semi-circular arc structure to form a space for fixing the iron cathode 2. The clamping plate 111 is located parallel to the outside of the telescopic connecting plate 3 and is connected to the movable buckle 114 by the fixing bolts 112 perpendicular to it. A pin 110 is inserted between the telescopic connecting plate 3 and the clamping plate 111 to clamp the iron cathode 2.
[0022] In this embodiment, the front end of the telescopic connecting plate 3 is connected to the fixed plate 4, and the adjusting handwheel 5 is connected to the rotating column 7; the lifting reducer 8 is fixedly installed on one side of the lifting fixed frame 10, and the lifting fixed frame 10 and the motor 9 are fixed on the ground.
[0023] In this embodiment, a handle 113 is installed above the movable buckle 114 to facilitate moving the movable buckle when disassembling or assembling the iron cathode.
[0024] In this embodiment, the telescopic connecting plate 3 and the movable buckle 114 are made of copper. The side that contacts the iron cathode 2 has a semi-circular arc structure that matches its size and shape, which can make close contact with the iron cathode 2 over a large range, increasing the contact area of the iron cathode by more than 30%, and greatly improving its conductivity, reducing the power consumption per unit product by 6-10%.
[0025] In this embodiment, a groove is provided below the movable buckle 114, and the shape and size of the groove match the symmetrically parallel fixed bolts.
[0026] In this embodiment, the self-consuming iron cathode is cylindrical, and the telescopic connecting plate 3 and the movable buckle 114 are provided with a groove with a semi-circular cross section on one side of the iron cathode 2. The shape and size of the groove match the shape and size of the iron cathode, so that the iron cathode 2 is clamped more securely.

[0028] The working principle and usage of this utility model: When installing the iron cathode, first move the iron cathode 2 to the side of the electrolytic furnace 1 and stand it upright. Position it using the semi-circular groove on the telescopic connecting plate 3, and then fit the iron cathode 2 into the semi-circular groove on the telescopic connecting plate 3. Next, insert the movable buckle 114 from top to bottom into the fixing bolt 112 using the handle 113. Then, insert the pin 110 between the telescopic connecting plate 3 and the clamping plate 111, and use a hammer to tap the pin 110 to lock the iron cathode 2 in place using the angle above the pin. Finally, the motor 9 drives the reducer 8 to lift the iron cathode 2 and move it closer to the center of the electrolytic furnace 1, completing the process of moving the iron cathode 2 into the electrolytic furnace 1.
[0029] When it is necessary to remove the iron cathode 2, the motor 9 drives the reducer to lift the iron cathode 2 away from the platform of the electrolysis furnace 1. Then, the rotating column 7 moves the iron cathode 2 away from the center of the electrolysis furnace and places it on the ground on one side of the electrolysis furnace 1. Then, the pin 110 is loosened and removed with a hammer. Then, the movable buckle 114 is picked up by the handle 113 and placed aside. This allows for the quick replacement of the iron cathode 2, reducing the time required to replace the iron cathode 2 and reducing the labor intensity of the workers.
