Problems solved by technology

[0004] At present, my country's molten salt electrolytic production of rare earth metal technology is at the leading level in the world. Although the technology is very advanced, the degree of automation of production control is not high. Most of the electrolytic rare earth preparation enterprises only rely on the experience of operators for manual cutting. In this way, it is easy to cause the rare earth oxides in the electrolyte to not be fully electrolyzed due to differences in worker experience, making it difficult to guarantee production efficiency and process stability, thereby increasing production costs
In addition, since the rare earth electrolysis temperature is as high as 1000°C, it is completely dependent on manual cutting, which makes the labor intensity of the workers very high, and the material is seriously flying

Embodiment 1

[0041] Such as figure 1 As shown, this embodiment provides an automatic feeding device for rare earth electrolysis, including a material temporary storage device 1 for controlling the total amount of feeding, a quantitative device 2 for controlling the single feeding amount of materials, and a device for evenly feeding materials. The feeding device 3; the material temporary storage device 1, the quantitative device 2 and the feeding device 3 are sequentially connected through the material channel to allow the materials to flow in sequence, and the outlet of the feeding device 3 extends above the rare earth electrolytic cell for feeding materials to the rare earth electrolytic cell ;

[0042] The material temporary storage device 1 can be any device or combination of devices that has the function of storing materials and transporting materials to other devices, such as a combination of a barrel and a material conveyor, and a preferred implementation mode adopted in this embodimen...

Embodiment 2

[0070] The controller used in this embodiment is as image 3As shown, the device can only be set for a single feeding amount under the user interface, and the button setting on the controller ensures that the equipment is easy to operate and prevents workers from causing system disturbance due to misoperation. From left to right on the control panel are k1, k2, k3, k4, the specific method of setting a single feeding amount: long press k1 in standby mode, it will display 000000, press k4 to move the cursor, press k3, it will display 000000, press k1, it will display Ed-001, press k4 to move the cursor, press k3 to modify it to 000x00, x is the set single feeding amount (unit: gram, if x is 3, it is 300g), press k1 to confirm the value, press k2 to return to control interface.

[0071] Under the administrator interface, the equipment can set the feeding times, feeding time interval, system delay time and electronic metering system correction and other functions. According to t...

experiment example

[0073] The automatic feeding equipment can realize regular, quantitative and uniform feeding in multiple feeding cycles, and the specific effects are shown in Table 1 (in the simulation test, an electronic scale is used to measure the actual feeding amount).

Abstract

The invention provides automatic feeding equipment for rare earth electrolysis and an operation method thereof, and relates to the technical field of feeding devices. The automatic feeding equipment comprises a material temporary storage device used for controlling the total feeding amount, a quantitative device used for controlling single feeding amount and a feeding device used for uniformly feeding materials, wherein the material temporary storage device, the quantitative device and the feeding device communicate with one another through a material channel in sequence so as to enable the materials to flow therethrough in sequence, and a discharging port of the feeding device extends to the position above a rare-earth electrolytic cell and is used for feeding the materials to the rare-earth electrolytic cell. The equipment is reasonable in design, the timing, quantitative and uniform feeding is realized through a three-stage feeding mode formed by arranging the material temporary storage device, the quantitative device and the feeding device, so that rare earth oxide in an electrolyte is sufficiently electrolyzed, the production efficiency is improved, and the stability of the process is ensured; and meanwhile, the labor intensity of workers and the flying loss of the materials can be reduced, and the environment of a production workshop is improved.

Description

technical field [0001] The invention relates to the technical field of feeding devices, in particular to an automatic feeding device for rare earth electrolysis and an operation method thereof. Background technique [0002] Rare earth is an important strategic resource, known as "industrial monosodium glutamate". Rare earth elements are very active metals, and it is difficult to extract them from their compounds by general methods under normal conditions. In industrial production, rare earth metals or their alloys are prepared from rare earth oxides, fluorides and chlorides by molten salt electrolysis and metal thermal reduction. Currently, molten salt electrolysis has been widely used in the large-scale production of rare earth metals. [0003] In the rare earth electrolysis process, sufficient electrolysis of rare earth oxides in the electrolyte is one of the important process parameters in the electrolysis process. If the content of rare earth oxides in the electrolyte...
