Description

Technical Field

[0001] The invention belongs to the technical field of rare earth metal production, and in particular relates to an automatic rare earth metal electrolysis furnace discharge device. Background Art

[0002] The rare earth molten salt electrolysis system can be divided into two types of electrolysis systems according to the different compositions of the electrolytes: one is the rare earth chloride electrolysis system, and the other is the rare earth oxide electrolysis system. During the electrolysis process, the rare earth metal ions are reduced to metals in the cathode region and settle in the crucible in the electrolysis furnace. Then, the metal in the crucible is taken out by special tools or the crucible is lifted out of the electrolysis furnace.

[0003] During the rare earth molten salt electrolysis process, the conventional method of taking rare earth metals out of the furnace is to use a manual scoop or a manual pot. However, this method is time-consuming, labor-intensive, and has poor safety performance, which increases the labor intensity of operators and reduces production efficiency.

[0004] The announcement number is CN218880093U, and the patent name is "A rare earth metal electrolysis automatic furnace discharge device". It discloses a controller, a base and a sliding plate, and the sliding plate is located above the base; a second driving member is provided at the top of the sliding plate away from the connecting rod, and the second driving member is electrically connected to the controller, and the output end of the second driving member is coaxially fixedly connected to a winding wheel, and a pull rope is wound around the winding wheel; a slide groove is provided at the bottom of the sliding plate, and a clamping device is provided in the slide groove, and the clamping device and the slide groove are horizontally slidably matched; one end of the pull rope is fixedly connected to the winding wheel, and the other end of the pull rope is fixedly connected to the clamping device, and other technical features include that the staff can adjust the height of the sliding plate according to the position of the crucible, thereby adjusting the height of the clamping device, and the connecting rod and the base can support the sliding plate, so that the sliding plate is more stable when moving up and down, and other technical features.

[0005] However, the defect of the above-mentioned comparative document is that the support seat is connected to the crane only by pull ropes and connecting ropes. However, in the high-temperature molten salt electrolytic furnace, the pull ropes and connecting ropes are not heat-resistant and reliable and are easy to break or deform, thereby affecting the subsequent clamping operation of the crucible. Since the pull ropes and connecting ropes fluctuate greatly, serious accidents such as the crucible tipping over may occur in severe cases. Therefore, based on the above-mentioned defects, the applicant proposed a better technical solution to solve the above-mentioned technical problems.
