[0002] Rare earth fluorides are a class of compounds composed of rare earth elements and fluorides, typically possessing a variety of advantageous properties. Rare earth fluorides refer to the fluorides of the lanthanides and 17 other rare earth elements, including scandium and yttrium. They are usually gray powders, insoluble in water but readily soluble in acids, and chemically stable. Rare earth fluorides have wide applications in optics, electronics, energy, and materials science. For example, they can be used to manufacture lenses, optical instruments, electronic components, high-energy-density batteries, and supercapacitors.

[0003] Rare earth fluorides do indeed generate a certain amount of waste gas during certain production processes, such as the anode process of molten salt electrolysis of rare earth fluoride systems.

[0004] Rare earth fluoride waste gas mainly occurs during rare earth smelting and processing, especially in the industrial production of rare earth oxide electrolysis in fluoride molten salt systems. In existing industrial production processes that generate rare earth fluoride waste gas, fluorination furnaces or electrolytic cells are used. However, the operation of these production equipment often requires manual removal and replacement of the cover plates used to collect the waste gas. This process is not only labor-intensive and inefficient in terms of waste gas treatment, but may also pose health risks.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in Figure 1 A schematic diagram of a preferred embodiment of a rare earth fluoride residual waste gas collection device provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the hollow rod in the right view. Figure 3 for Figure 1 The diagram shows the structural schematic of the left view of the processing box.

[0024] Figure 4 for Figure 1 The structural schematic diagram of the hollow rod cross-section shown is a rare earth fluoride residual waste gas collection device, including: a base 1, a plate replacement assembly 2 is provided on the top of the base 1, and a waste gas treatment assembly 3 is provided on the top of the base 1 and on the top of the plate replacement assembly 2.

[0025] The plate changing assembly 2 includes a hollow rod 21 that is rotatably disposed at the top middle part of the base 1 in the longitudinal direction. A support rod 22 is provided on the inner side of the hollow rod 21 that can slide up and down along its length. A rotating plate 23 is fixedly disposed on the top of the support rod 22.

[0026] With the support rod 22 that can move up and down and the hollow rod 21 that can rotate, when the cover plate 24 needs to be replaced, the support rod 22 is placed upward inside the hollow rod 21, and then the hollow rod 21 is rotated to make the rotating plate 23 rotate, thereby making the suction hood 26 above the electrolytic cell 25, and then the suction hood 26 falls down to absorb the waste gas from the electrolytic cell 25.

[0027] The exhaust gas treatment component 3 is installed on the top of the rotating plate 23 with a suction fan 31. The air outlet on the left side of the suction fan 31 is connected to the treatment box 32. A set of treatment plates 33 is installed on the inner wall of the treatment box 32, which can slide back and forth.

[0028] The dry treatment method involves physical or chemical reactions between the adsorbent and the fluorides in the waste gas, fixing the fluorides onto the adsorbent and thus purifying the waste gas. The interior of the treatment plate 33 contains the adsorbent, such as sodium fluoride, limestone, or alumina.

[0029] A cover plate 24 is provided on the left side of the bottom of the rotating plate 23, an electrolytic cell 25 is provided at the bottom of the cover plate 24, and an air suction hood 26 is provided on the right side of the bottom of the rotating plate 23.

[0030] A large gear 27 is provided at the bottom of the side of the hollow rod 21. A drive motor 28 is provided on the inner side of the base 1. The output end of the drive motor 28 passes through the inner side of the base 1 and extends to its top. A small gear 29 is provided on the top of the output end of the drive motor 28. The small gear 29 meshes with the large gear 27.

[0031] The rotation of the output end of the drive motor 28 drives the rotation of the pinion 29, which in turn drives the rotation of the large gear 27 and the hollow rod 21. By having the pinion 29 drive the large gear 27, the torque force can be increased while the rotation angle can be controlled more precisely.

[0032] The plate changing assembly 2 also includes a telescopic cylinder 4 disposed at the bottom of the inner wall of the hollow rod 21, and the telescopic end of the top of the telescopic cylinder 4 is fixedly connected to the bottom end of the support rod 22.

[0033] The support rod 22 is slidably connected to the inner wall of the hollow rod 21. When the hollow rod 21 rotates, it will drive the support rod 22 to rotate synchronously.

[0034] The front of the processing plate 33 is provided with a handle 34. The suction pipe on the right side of the suction fan 31 passes through the top of the rotating plate 23 and extends to its bottom. The suction pipe of the suction fan 31 is connected to the top of the suction hood 26. The front side of the top of the suction hood 26 is connected to an air exchange pipe 35.

[0035] The processing plate 33 can be pulled out using handle 34 for easy replacement.

[0036] A fixing block 5 is provided on the right side of the hollow rod 21. A sliding rod 6 is provided on the inner side of the fixing block 5, which can slide up and down. The top of the sliding rod 6 is fixedly connected to the bottom of the rotating plate 23. Hooks 7 are provided on both the front and rear sides of the electrolytic cell 25. Hanging grooves for use with the hooks 7 are provided on both the front and rear sides of the cover plate 24.

[0037] During the production process, the cover plate 24 can be firmly fixed and sealed to the top of the electrolytic cell 25 by hook 7. When changing the suction hood 26, it is only necessary to manually remove the hook 7 from the fixation.

[0038] The working principle of the rare earth fluoride residual waste gas collection device provided by this utility model is as follows:

[0039] Step 1: When the production equipment is finished and exhaust gas needs to be discharged, the hook 7 is manually removed from the cover plate 24. The extension of the output end of the telescopic cylinder 4 drives the rotating plate 23 to rise, which in turn drives the cover plate 24 to rise. The rotation of the output end of the drive motor 28 drives the small gear 29 to rotate, which in turn drives the large gear 27 and the hollow rod 21 to rotate, thus making the cover plate 24 rotate. At the same time, the suction hood 26 rotates and is directly above the electrolytic cell 25. At this time, the output end of the telescopic cylinder 4 retracts, so that the suction hood 26 covers the top of the electrolytic cell 25.

[0040] Step 2: The exhaust gas inside the electrolytic cell 25 is continuously drawn out by the operation of the suction fan 31 and finally discharged into the treatment box 32. Through the dry treatment method, the fluoride in the exhaust gas undergoes physical or chemical reaction with the adsorbent, fixing the fluoride on the adsorbent, thereby purifying the exhaust gas. The treatment plate 33 can be easily pulled out by the handle 34 for replacement.

[0041] Compared with related technologies, the rare earth fluoride residual waste gas collection device provided by this utility model has the following beneficial effects:

[0042] The extension of the output end of the telescopic cylinder 4 drives the rotating plate 23 to rise, which in turn drives the cover plate 24 to rise. The rotation of the output end of the drive motor 28 drives the small gear 29 to rotate, which in turn drives the large gear 27 and the hollow rod 21 to rotate, thus causing the cover plate 24 to rotate. At the same time, the suction hood 26 rotates and is positioned directly above the electrolytic cell 25. At this time, the output end of the telescopic cylinder 4 retracts, so that the suction hood 26 covers the top of the electrolytic cell 25. The structure is simple and practical, greatly saving manual labor and improving the efficiency of waste gas treatment.
