[0002] Scandium (Sc) is one of the rare earth elements. Scandium metal is very chemically active and easily reacts with oxygen, water, carbon dioxide, acids, halogens and other gases to form corresponding compounds, and quickly loses its metallic luster. Scandium is particularly dispersed in nature, and there are basically no independent scandium minerals. Usually, most scandium elements are dispersed in other minerals. Therefore, in the process of recycling scandium metal elements, it is necessary to react scandium with a precipitant to separate other elements from scandium elements. Therefore, a scandium waste precipitation recovery device is needed.

[0003] Existing scandium waste is generally stored directly in a container, and then a precipitant is sprayed to react with the scandium waste. However, the precipitant is generally sprayed to the top of the scandium waste, which makes it inconvenient to mix the precipitant with the inside of the scandium waste, resulting in a slow efficiency of the precipitant when reacting with the scandium waste, further reducing the working efficiency of the recovery device.

[0004] For this purpose, we propose a scandium waste precipitation and recovery device. Utility Model Content

The surface of the gear plate 1 63 is meshingly connected to a gear plate 2 64. The gear plate 2 64 is fixed to the surface of the hollow shaft 3. Driven by the driving component 4, the hollow shaft 3 can be rotated. When the hollow shaft 3 rotates, the mixing mechanism 6 can also be driven to rotate. When the mixing mechanism 6 rotates, the scandium waste inside the sedimentation tank 1 can be stirred, so that the precipitant can be better integrated to react. When the mixing mechanism 6 rotates, the scandium waste can be crushed, which further improves the reaction efficiency of the scandium waste and the precipitant.

[0023] In addition, the driving part is a motor and a gear. The rotation of the motor can drive the gear to rotate. The rotation of the gear can rotate the gear plate 2 64 on the surface of the hollow shaft 3, thereby driving the hollow shaft 3 and the mixing mechanism 6.

[0024] according to Figure 2 It can be seen that the stirring assembly 61 includes a stirring frame 611 fixed on the surface of the hollow shaft 3, the interior of the stirring frame 611 is rotatably connected to a bevel gear 1 612 through a bearing, the interior of the bevel gear 1 612 penetrates and is connected to the rhombus column 62, the surface of the bevel gear 1 612 is meshedly connected to a bevel gear 2 613, the surface of the bevel gear 2 613 is fixedly connected to a crushing roller 614, the end of the crushing roller 614 rotates inside the stirring frame 611 through a bearing, is installed on the surface of the hollow shaft 3 through the stirring frame 611, and then is installed on the surface of the rhombus column 62 through the bevel gear 1 612, so that when the rhombus column 62 rotates, it can drive the bevel gear 2 613 meshed with the bevel gear 1 612 to rotate, and when the bevel gear 2 613 rotates, the crushing roller 614 can be rotated. Since the crushing roller 614 is inside the sedimentation tank 1, it can crush the scandium waste, thereby converting the scandium waste into a smaller shape, so that it can better react with the precipitant.

[0025] In addition, the diamond column 62 and the bevel gear 1 612 are tightly installed so that the diamond column 62 does not need additional support force, thereby ensuring the meshing effect between the gear plate 1 63 and the gear plate 2 64 at the end of the diamond column 62.

[0026] according to Figure 4 It can be seen that two guide plates 615 are connected to the front of the stirring frame 611. The two guide plates 615 are in a trumpet shape.

[0029] according to Figure 2 It can be seen that the storage assembly 5 includes a storage box 51 fixed on one side of the sedimentation tank 1, and a water pump 52 is fixedly connected to the top of the storage box 51. The water inlet end of the water pump 52 is connected to the inside of the storage box 51 through a pipe, and the water outlet end of the water pump 52 passes through the inside of the hollow shaft 3 through a pipe. Under the setting of the storage box 51, it is convenient to store the precipitant. When in use, it is driven by the water pump 52 to extract the precipitant inside the storage box 51, and then transport it to the inside of the hollow shaft 3 through a pipe for injection treatment and use.

[0030] The working principle of the utility model is as follows: when in use, the sedimentation tank 1 is first used to collect the scandium waste, and then the bearing support frame 2 can support the hollow shaft 3 and the driving component 4 respectively.

When the hollow shaft 3 rotates, the storage component 5 can be driven so that the precipitant inside the storage component 5 can be transported to the inside of the hollow shaft 3 through the pipeline, and then the precipitant can be better sprayed into the inside of the scandium waste through the hollow shaft 3. When the hollow shaft 3 is driven, the mixing mechanism 6 can be driven synchronously so that the scandium waste and the precipitant can be mixed. Mixing, so that the mixing reaction can be better carried out. When the mixing mechanism 6 is working, the stirring component 61 is first installed on the surface of the hollow shaft 3, so that when the hollow shaft 3 rotates, the stirring component 61 can be synchronously driven to rotate, so that the scandium waste inside the sedimentation tank 1 can be stirred and mixed, and through the rotation of the gear plate 2 64, it can drive the diamond column 62 fixed by the gear plate 1 63 to work. When the diamond column 62 rotates, it can synchronously drive the inside of the stirring component 61 to drive, so as to crush the scandium waste and the precipitant. After the scandium waste and the precipitant are fully reacted, the scandium ions and impurities are discharged through the discharge pipe 7.
