Description

Technical Field

[0001] The invention relates to the field of rare earth production devices, and in particular to a rare earth continuous electrolysis device. Background Art

[0002] Nowadays, extraction separation-precipitation method, molten salt electrolysis method, vacuum reduction method, etc. are commonly used to prepare rare earth compounds, rare earth metals and rare earth alloys. Molten salt electrolysis method is the mainstream process for preparing single rare earth metal, mixed rare earth metal and rare earth alloy due to its purity advantage. Molten salt electrolysis method is a method for preparing rare earth metals in which rare earth ions in rare earth-containing molten salt electrolyte obtain electrons at the cathode of electrolytic furnace (also called electrolytic cell) under the action of direct current and are reduced to metals. Under the existing technology, the anode often needs the participation of staff to replace it after it is consumed, which increases the labor force and reduces the replacement production efficiency of the electrolytic furnace, which is not conducive to the efficient production of the electrolytic furnace.

[0003] The present invention is proposed in view of the deficiencies in the prior art. Summary of the invention

[0004] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide a rare earth continuous electrolysis device.

[0005] The present invention can be implemented by the following technical solutions:

[0006] The invention discloses a rare earth continuous electrolysis device, comprising an electrolytic cell, wherein a sliding rod and a screw rod are arranged on the electrolytic cell, the screw rod is driven to rotate by a feeding motor, a slide table is arranged on the screw rod, the screw rod passes through the slide table and is threadedly connected to the slide table, the sliding rod passes through the slide table and is slidably connected to the slide table, a turning motor is fixed on the slide table, a fixing plate is fixed on the output end of the turning motor, two fixing shafts are arranged on the fixing plate, the fixing shafts are driven to rotate by an electric telescopic rod, fixing pipes are fixed on the fixing shafts, fixing rods are fixed on the fixing pipes, fixing blocks are fixed on the ends of the fixing rods, a feeding trough is also fixed on the electrolytic cell, a rotating disk is also arranged on the electrolytic cell, a material receiving trough is evenly arranged on the rotating disk, the rotating disk is driven to rotate by a material receiving motor, a cathode is also fixed in the electrolytic cell, a plurality of anodes are placed in the feeding trough, a connecting rod is fixed on the top of the anode, a limiting block is fixed on the end of the connecting rod, and an electrode electrically connected to a power supply is also arranged on the fixing block. The anodes are evenly placed in the feeding trough, and the feeding motor drives the screw to rotate. Since the screw is threadedly connected to the slide, when the screw rotates, the slide moves in the direction of the screw. After the two fixed blocks reach the two sides of the connecting rod at the discharge port, the electric telescopic rod starts, the electric telescopic rod extends, and the two fixed blocks approach each other. The two fixed blocks close together to grab the connecting rod. After the connecting rod is fixed by the fixed blocks, the feeding motor drives the screw to rotate in the opposite direction, and the two fixed blocks pull the anodes at the bottom layer in the feeding trough out of the feeding trough. After the anode is separated from the feeding trough, the flipping motor starts, and the flipping motor drives the fixed plate to rotate. The anode rotates with the fixed plate, and the end of the anode enters the electrolyte, and the electrolyte is ionized through the anode and cathode. Electrolysis is carried out, and the rare earth metal solution slides into the crucible for collection after being precipitated at the cathode. When a certain amount of anode is consumed, the flipping motor is started again, and the fixed plate rotates a certain angle again. After the anode is facing a receiving slot on the turntable, the feeding motor drives the screw to rotate, and the slide moves toward the turntable. After the anode is inserted into the receiving slot on the turntable, the electric telescopic rod is shortened, and the two fixed blocks are separated. The screw is driven to rotate by the feeding motor again, and the fixed plate is driven to rotate by the flipping motor again. The two fixed blocks reach the two sides of the connecting rod at the discharge port again, and the cycle operation is carried out.
