Description

Technical Field

[0001] This utility model relates to the field of rare earth metal electrolytic smelting technology, specifically to a self-priming rare earth electrolytic automatic metal output device. Background Technology

[0002] Rare earth metals, due to their unique magnetic, optical, and electrical properties, are widely used in new energy vehicles, wind power, high-end manufacturing, and electronic information, possessing extremely high strategic value. With the continued growth in demand from downstream industries, rare earth smelting enterprises are accelerating their transformation towards intelligent, efficient, and green processes. In the electrolytic smelting process, the periodic extraction of molten rare earth metals from the electrolytic furnace crucible is a crucial step, directly affecting metal yield and process stability. Therefore, higher requirements are placed on the high-temperature resistance, corrosion resistance, operational efficiency, and safety of the metal extraction equipment.

[0003] Currently, most smelting enterprises still use traditional siphon, spoon, or crucible methods to extract metal, but these methods still have many shortcomings. For example, manual operation exposes the operator to the vicinity of high-temperature molten metal, posing safety hazards such as burns and splashes; robotic arms are prone to corrosion and have short lifespans; and liquid level control relies on manual judgment, leading to uneven extraction, metal waste, or emptying of the crucible. Utility Model Content

[0004] The purpose of this invention is to provide a self-priming automatic rare earth electrolysis metal extraction device, which aims to solve the technical problems of high temperature danger, severe corrosion and low efficiency in the traditional manual operation of rare earth smelting process.

[0005] To achieve the above objectives, this utility model provides a self-priming rare earth electrolysis automatic metal extraction device, including an electrolysis device, a suspension device, a driving device, and a self-priming device. The suspension device is frame-type, the driving device and the self-priming device are respectively mounted on the suspension device, and the electrolysis device is located inside the suspension device and below the self-priming device.

[0006] The electrolysis device is arranged in a multi-station configuration. Each station includes an electrolysis furnace, a cathode rod, an anode plate, and a crucible. The electrolysis furnace is configured as an electrolysis cell. A cathode rod is vertically fixed at the center of each electrolysis furnace. The anode plates are detachably arranged around the electrolysis cell. The anode plates are either L-shaped or U-shaped. L-shaped anode plates are arranged at the edge of the electrolysis cell, and U-shaped anode plates are arranged on the side walls of two adjacent electrolysis cells. The crucible is arranged at the bottom of the electrolysis cell.

[0007] The cathode rod is connected to the negative terminal of the power supply, and the anode plate is connected to the positive terminal of the power supply.

The vertical guide rail truss is mounted on the drive device and remains perpendicular to the ground.

[0009] The vertical guide rail truss is provided with vertical guide rails, and both the vertical guide rails and the guide rails are provided with tracks and helical racks.

The rollers, helical gears, reducers, and motors are respectively mounted on the fixed frame plate. There are two sets of each helical gear, reducer, and motor. Each track is adapted to four rollers. The helical gears mesh with the helical rack.

[0011] The self-priming device includes a box, a mold, a magnetic pump, a feeding suction pipe, a discharging suction pipe, a motor, and a conveyor belt.

[0015] This invention provides a self-priming automatic rare earth electrolysis metal extraction device, comprising an electrolysis unit, a suspension unit, a drive unit, and a self-priming unit. The suspension unit is frame-type, with the drive unit and self-priming unit respectively mounted on it. The electrolysis unit is located inside the suspension unit and below the self-priming unit. This invention utilizes an electrolysis furnace within the electrolysis unit to perform a rare earth electrolysis reaction, causing molten rare earth metal to deposit in a crucible. The drive unit then activates, precisely positioning the feed pipe of the self-priming unit onto the corresponding crucible. The molten rare earth metal solution is drawn out through the feed pipe and a magnetic pump into a mold within the chamber.

[0072] 5. Mold Removal Fork 5: This allows you to remove the mold shown in the image.

[0073] The process is as follows:

[0074] Before electrolysis begins in electrolytic furnace 101, drive device 3 drives the housing 401 to the standby area on one side of electrolytic furnace 101. After the housing 401 reaches the designated area, the mold is manually placed into the housing 401, and the housing door 406 is closed. At this time, the three-station electrolytic furnace 101 starts working intermittently. As electrolysis continues for the specified time, a certain amount of molten rare earth metal is deposited in the crucible 104 below the cathode rod 102 of the electrolytic furnace 101 that started electrolysis first (referred to as the first station, and the other two electrolytic furnaces are the second and third stations, respectively). At this time, drive device 3 is activated, and the feed suction pipe 404 connected to the magnetic pump is precisely positioned to the first station. At the bottom of the crucible 104, the magnetic pump 403 starts working, sucking the rare earth metal solution deposited in the crucible 104 through the pipette and the magnetic pump 403 and discharging it into the mold 402 in the box 401. The loading capacity of the mold 402 is adapted to one crucible 104. After the mold 402 is full, the magnetic pump 403 stops working and is automatically driven to the standby area for static cooling by the drive device 3. After the specified cooling time, the box door 406 is opened and the cooled mold is manually removed and an empty mold is placed for later use. The box door 406 is closed and the electrolysis of the second station is waited for to be completed. After the electrolysis of the second station is completed, the steps of the first station are repeated...
