Description

Technical Field

[0001] The utility model belongs to the technical field of rare earth electrolytic metal feeding, and particularly relates to an automatic feeding device for rare earth electrolytic metal. Background Art

[0002] Rare earth electrolytic metal refers to the process of preparing rare earth metals from rare earth compounds by electrolysis. The electrolysis method utilizes the electrolysis principle to pass an electric current through certain electrolyte solutions, and redox reactions occur on the electrodes, thereby preparing the required metals. In the preparation of rare earth metals, the electrolysis method is widely used due to its advantages such as continuous production, large output, simple equipment, and low cost. Among them, the automatic feeding device for rare earth electrolytic metal is a device used to automatically and accurately add raw materials into the electrolytic cell during the electrolysis process of rare earth metals. This device can significantly improve production efficiency, reduce labor intensity, and ensure the accuracy and stability of the feeding amount.

[0003] The feeding device for rare earth metal electrolysis with the publication number "CN212831632U" includes a feeding hopper; characterized in that a primary crushing component and a secondary crushing component are sequentially arranged in the inner cavity of the feeding hopper from top to bottom. The lower end of the feeding hopper is spatially communicated with the feeding port on one side of the upper end of the feeding and guiding pipe through a connecting cavity, and the feeding and guiding pipe is fixedly connected to the upper end of the bearing seat; a screw rod is arranged in the feeding and guiding pipe, and fixed seats are arranged at both inner cavity openings at both ends of the feeding and guiding pipe. Both ends of the screw rod are rotatably connected to the fixed seats at both ends of the feeding and guiding pipe; one end of the screw rod close to the feeding port is drivingly connected with a driving component, and a spiral blade is sleeved on the screw rod; the utility model can fully and effectively perform multi-stage repeated crushing on the materials entering the feeding hopper, and finally ensure that the particle size of the raw materials entering the electrolytic furnace is uniform, accelerating the reaction degree and reaction efficiency of the materials.

[0004] Although the above-mentioned utility model can fully and effectively perform multi-stage repeated crushing on the materials entering the feeding hopper, and finally ensure that the particle size of the raw materials entering the electrolytic furnace is uniform, accelerating the reaction degree and reaction efficiency of the materials, it is impossible to adjust the distance between the shaft rollers, so that the particle size of the crushed materials will also remain relatively fixed and cannot be adjusted according to actual needs. This will cause some materials to be too fine or too coarse, affecting the treatment effect of subsequent processes. Moreover, for materials with different hardness and sizes, the fixed distance between the shaft rollers may not achieve the optimal crushing effect, thereby reducing the crushing efficiency. Summary of the Utility Model

[0005] Aiming at the problems mentioned in the background technology, the purpose of the present utility model is to provide an automatic feeding device for rare earth electrolytic metal, so as to solve the problem that the distance between the shaft rollers cannot be adjusted, resulting in the particle size of the crushed material remaining relatively fixed and unable to be adjusted according to actual needs. This will cause some materials to be too fine or too coarse, affecting the treatment effect of subsequent processes. Moreover, for materials with different hardnesses and sizes, a fixed shaft roller distance may not achieve the optimal crushing effect, thereby reducing the crushing efficiency.

[0006] The above technical purpose of the present utility model is achieved through the following technical solutions:

Moreover, a reasonable roller distance setting can reduce the energy consumption and wear during the crushing process, improve the crushing efficiency, and at the same time, adjusting the distance between the crushing rollers can enable the equipment to better adapt to the characteristics of different materials, achieving an efficient and stable crushing effect.

[0009] As a preferred technical solution, T-shaped grooves are symmetrically formed at one end of the feeding hopper away from the third driving motor, and T-shaped blocks are symmetrically and fixedly connected to one end of the second mounting seat away from the third driving motor. The T-shaped blocks are slidably connected to the T-shaped grooves, improving the stability and accuracy of the movement of the crushing rolls.

[0010] As a preferred technical solution, the heating assembly includes a heating box, a heating base, heating columns, and a retaining net. Heating boxes are symmetrically and embeddedly installed at both ends of the feeding hopper. Heating bases are symmetrically and fixedly connected to both ends inside the heating boxes. Heating columns are fixedly connected to the opposite ends of the heating bases. A retaining net is threadedly connected to one end of the heating box close to the inside of the feeding hopper. It can rapidly increase the temperature of the rare earth electrolytic metal, accelerate the evaporation of moisture on its surface and inside, thus quickly achieving thawing, significantly improving the thawing efficiency, and can effectively remove moisture, reducing the electrolyte fluctuations caused by moisture evaporation during the electrolysis of the wet rare earth electrolytic metal, ensuring the stability of the electrolysis process.
