Description

Technical Field

[0001] This utility model belongs to the field of chemical engineering technology, and in particular relates to a rare earth chloride dissolution device. Background Technology

[0002] Rare earth chlorides are compounds formed by rare earth elements and chlorine, usually existing in the form of chlorides. Rare earth chlorides are widely used in the extraction and separation of rare earth metals and also have important applications in certain industrial fields. Rare earth chloride dissolving equipment is a device specifically designed to dissolve rare earth chlorides in solvents. This type of equipment plays an important role in the extraction, separation, refining, and chemical reaction processing of rare earth elements, especially in the rare earth smelting process, where rare earth chlorides usually need to be dissolved first for further processing.

[0003] Existing rare earth chloride dissolving equipment typically places the rare earth chloride directly inside the device for dissolution. However, rare earth chloride is usually a solid, and direct dissolution may affect the dissolution efficiency. If the rare earth chloride can be crushed and rolled before dissolution to increase its surface area, the dissolution rate can be improved. Therefore, we propose a rare earth chloride dissolving equipment. Utility Model Content

[0028] One specific application of this embodiment is: When staff need to use the equipment, they can start the first motor 206 and the second motor 308 through the control panel 102, and then add rare earth chlorides into the housing 201. At this time, the first motor 206 will drive the second rotating shaft 207 to rotate, so that the second rotating shaft 207 can drive the second crushing roller 204 to rotate in the housing 201. At the same time, the second crushing roller 204 will also drive the second gear 209 to rotate, so that the second gear 209 can drive the first gear 208 to rotate. Then the first gear 208 will drive the first rotating shaft 203 to rotate. At this time, the first rotating shaft 203 will also drive the first crushing roller 202 to rotate in the housing 201. Then the first crushing roller 202 and the second crushing roller 204 will crush the rare earth chlorides, achieving the effect of crushing the rare earth chlorides before they dissolve, increasing the surface area of ​​the rare earth chlorides and thus accelerating the dissolution rate. Simultaneously, the second rotating shaft 207 will also drive the first pulley 218 to rotate. At this time, the first pulley 218 drives the second pulley 219 to rotate via the belt. At this time, the second rotating shaft 207 will also drive the third pulley 220 to rotate. The third pulley 220 will also drive the fourth pulley 221 to rotate via the belt. At this time, the second pulley 219 and the fourth pulley 221 will drive the worm gear 222 to rotate. Then, the worm gear 222 will drive the worm wheel 214 to rotate, so that the worm wheel 214 drives the turntable 212 to rotate via the rotating rod 213. Then, the turntable 212 drives the offset shaft 215 to make a circular motion along the turntable 212. At this time, the offset shaft 215 will drive the push plate 217 to reciprocate within the housing 201 via the straight groove 216, so that the push plate 217 pushes the rare earth chloride salt falling on the horizontal inner wall of the housing 201. At this time, the push plate 217 will drive the limiting block 223 to slide on the limiting rod 224, and the straight groove 216 will also drive the L-shaped rod 225 to slide along the limiting rod 224. Then, the rare earth chloride will enter the dissolving tank 301. At this time, the second motor 308 will drive the third rotating shaft 309 to rotate, so that the third rotating shaft 309 drives the cross-shaped insert 310 to rotate. Then, the cross-shaped insert 310 will drive the rotating column 306 to rotate through the cross groove 311. After that, the rotating column 306 drives the stirring rod 307 to rotate to stir the rare earth chloride and solvent. After the stirring and dissolution are completed, the device can be stopped and left to stand for a period of time. At this point, the insoluble matter in the solution will fall onto the filter plate 304. Then, the top cover 103 can be removed, and the connecting ring 303 can be lifted upwards through the insert plate 302. At this time, the connecting ring 303 will drive the filter plate 304 to move upwards. Simultaneously, the filter plate 304 will also drive the rotating column 306 to move upwards through the limiting cylinder 305, causing the rotating column 306 to disengage from the third rotating shaft 309. Thus, the rotating column 306 and the filter plate 304 can be removed from the dissolving tank 301 as a whole. At this time, the impurities will be carried out along with the filter plate 304, leaving the solution in the dissolving tank 301. This achieves the effect of quickly filtering the solution after the rare earth chloride salt is dissolved.
