[0032] In order to make the purpose, technical scheme and advantages of the implementation of the utility model clearer, the utility model will now be further described in detail with reference to the accompanying drawings and the following examples so that the public can better understand the implementation method of the utility model. The specific implementation scheme of the utility model is as follows:

[0033] The cathode lifting device of the rare earth molten salt electrolytic furnace comprises a fixed frame 1, a vertical linear slide 14 is fixedly arranged on the outer surface of the fixed frame 1, and the fixed frame 1 is connected to the support frame 2 through the vertical linear slide 14; a rotary drive 3 is arranged on the lower end surface of one side of the support frame 2 in a fixed structure mode, a rotating frame 4 is arranged on the lower end of the rotary drive 3 in a fixed structure mode, and an insulating clamping mechanism 5 is arranged on the rotating frame 4 in a sliding structure mode, and the insulating clamping mechanism 5 is used to fix the conductive copper bar 6, and a cathode rod 7 is arranged on one end of the conductive copper bar 6 in a fixed structure mode; the driving mechanism is connected to the rotating frame 4 to drive the insulating clamping mechanism 5 to reciprocate in the rotating frame 4. The cathode rod is driven to rotate to one side of the furnace body by the rotary drive 3 to prevent objects on the cathode rod from falling off and falling on the operator, thereby eliminating safety hazards.

[0034] It should be noted that the rotating frame 4 is arranged in a U-shaped structure, and a horizontal linear guide rail 8 is arranged inside the rotating frame 4; the horizontal linear guide rail 8 is fixedly arranged on the inner wall of the rotating frame 4, and the rotating frame 4 is connected to the insulating clamping mechanism 5 through the horizontal linear guide rail 8, which facilitates the movement of the insulating clamping mechanism 5 and further determines the extension amount of the conductive copper busbar.

[0035] Specifically, the driving mechanism includes a rack 91, a gear 92 and a rotating shaft 93. The rack 91 is connected to the insulating clamping mechanism 5 in a fixed structure manner. The rack 91 is meshed and connected to the gear 92. The gear 92 is rotatably connected to the rotating frame 4 through the rotating shaft 93. The rotating shaft 93 passes through the side wall of the rotating frame 4 and is provided with a handwheel 94 in a fixed structure manner. The insulating clamping mechanism 5 is driven to move by providing the gear 92 and the rack 93. It can be installed once and can cover the furnace body within a certain range. The structure is simple and the scope of use is expanded.

[0036] It should be explained that the insulating clamping mechanism 5 includes a mounting frame 51, and insulating plates 52 are arranged on two opposite sides of the mounting frame 51. The side arms of the mounting frame 51 are provided with tightening bolts 53 through threaded engagement. One end of the tightening bolts 53 passes through the side arms of the mounting frame 51 and contacts the outer wall of the insulating plates 52, so as to press the insulating plates 52 onto the conductive copper busbar and fix them. Support blocks are arranged on the upper and lower end surfaces of the two insulating plates 52. The support blocks of the two insulating plates 52 form a staggered structure, which can have a certain sliding space and can also place the conductive copper busbar in contact with the mounting frame 51, thereby improving safety.

[0037] A fixed block 10 is arranged inside the rotating frame 4, and a slide groove is opened on the fixed block 10. Two clamping blocks 11 for locking the horizontal linear guide rail 8 are arranged in the sliding structure in the slide groove. The slide groove can limit the clamping block 11 to ensure that it can only slide along the slide groove. Positive and negative thread screws 12 are arranged on the clamping block 11. One clamping block 11 is engaged with the positive thread of the screw 12, and the other clamping block 11 is engaged with the negative thread of the screw 12. The screw 12 is connected to the fixed block 10 in a rotating structure. A handle 13 is arranged at one end of the screw 12 through the fixed block 10 to prevent the movement of the insulating clamping mechanism and the conductive copper busbar caused by centrifugal force during the rotation process, which affects the accuracy of the subsequent falling at the furnace mouth.

[0038] The working principle and working process of the utility model are as follows:

[0039] Tighten the tightening bolt 53 to press the conductive copper bar 66 between the two insulating plates; turn the hand wheel 94, the hand wheel 94 drives the gear 92 to rotate through the rotating shaft 93, and then drives the insulating clamping mechanism to move to a predetermined position through the rack 92, which can ensure that the cathode rod can extend into the furnace body after falling, and then turn the handle 13, and drive the two clamping blocks 11 to move toward each other through the rotation of the screw 12, so as to clamp the horizontal linear guide 8.

[0040] Then start the rotary drive 3, driving the rotating frame 4, the insulating clamping mechanism 5, the conductive copper bar 6 and the cathode rod 7 to rotate until the cathode rod 7 is located above the furnace mouth, and drive the support frame 2 to move downward through the vertical linear slide 14, thereby driving the rotary drive 3, the rotating frame 4, the insulating clamping mechanism 5, the conductive copper bar 6 and the cathode rod 7 to descend until the cathode rod reaches the predetermined position.

[0041] When the cathode rod needs to be taken out, the vertical linear slide 14 needs to be started to drive the support frame 2 to move upward. After the cathode rod 7 is taken out of the furnace body, the rotary drive 3 is started to drive the cathode rod 7 to rotate to the side of the furnace mouth to take out the molybdenum pot.
