After the drying and dehydration are completed, the obtained anhydrous rare earth chloride product is transferred back to the feeding space F from the heating cavity H through the feeding device 30.

It will be appreciated that the lifting end of the lifting frame can be lifted and moved relative to the fixed end, and the loading member 333 is disposed at the lifting end. The lifting direction of the lifting frame corresponds to the X-direction in fig. 1, the loading element 333 being in a first position, i.e. in a low position during lifting, and in a second position, i.e. in a high position during lifting.

Still further, the driving part 331 further includes a lifting rail (not shown) disposed in the feeding space F along a lifting direction of the lifting frame, and the loading part 333 can be lifted along the lifting rail by the driving of the lifting frame.

Wherein the lifting guide rail can be one or more. The loading unit 333 is provided with a guide hole in the lifting direction at its own center position, through which a lifting guide is provided. In addition, the elevating guide rail may be provided at the circumferential side of the loader 333.

The elevation guide rail can guide the loading member 333 during its elevation so that it can be smoothly elevated in the feeding space F. The portion of the load 333 that enters the heating chamber H can then be guided by the chamber walls of the heating chamber H.

The heating device 10 can directly adopt an atmosphere furnace to act as a heating chamber, and can enter air through an air inlet I and exhaust air through an air outlet E to form a required atmosphere in a heating cavity H. It is understood that the air inlet I and the air outlet E are respectively connected with the air inlet pipe 111 and the air outlet pipe 113. In addition, the cavity tube 11 may be formed with other air inlet and outlet interfaces to meet the air inlet requirements of different atmospheres, which is not particularly limited herein.

When the heating device 10 dehydrates the rare earth chloride crystal raw material, argon gas can be firstly introduced into the heating cavity H through the air inlet I to create an argon gas atmosphere. With the introduction of argon and the gradual increase of the temperature in the heating cavity H, the free water of the rare earth chloride crystal raw material is gradually removed. After the temperature is raised to a set value, hydrogen chloride gas can be introduced to create a hydrogen chloride atmosphere, and the rare earth chloride crystal raw material is further dehydrated under the hydrogen chloride atmosphere to obtain an anhydrous rare earth chloride product.

Optionally, the heating device 10 further includes a temperature detecting member and an alkali spray absorbing device, and the thermocouple 15 is used for detecting the heating temperature of the heating member 13. The alkali spray absorption device is used for absorbing the hydrogen chloride gas discharged from the gas outlet E.

Specifically, the cavity tube 11 is disposed along the longitudinal direction thereof in the lifting direction, one end thereof is connected to the feeding device 30, and the loading member 333 is capable of loading material into and out of the heating chamber H from the end of the cavity tube 11 connected to the feeding device 30.

In the material dehydration and operation system 100, the feeding device 30 is integrally connected with the operation device 50, and the heating device 10 is disposed above the feeding device 30. The operator can close the first sealing door 35 after placing the crucible 200 containing rare earth chloride crystal raw material at the top end of the loader 333 from the feed port P by opening the first sealing door 35. After the first sealing door 35 is closed, argon is introduced into the operation space O, the feed space F, and the heating chamber H to sufficiently exhaust air. The lifting frame lifts the loading part 333 until the loading part 333 enters the heating cavity H, and the base 335 seals the heating cavity H to isolate the heating cavity H from the operation space O. At this time, argon gas is introduced into the heating chamber H, and the temperature is raised and heated by the heating element 13, so that free water of the rare earth chloride crystal raw material is removed. After the temperature detected by the thermocouple 15 reaches a set value, the argon gas is stopped being introduced, the hydrogen chloride gas is introduced, and the rare earth chloride crystal raw material is dehydrated in the atmosphere of hydrogen chloride to obtain an anhydrous rare earth chloride product. The hydrogen chloride gas discharged from the gas outlet E is absorbed by the alkali spray absorbing device.

After the dehydration is completed, argon is again introduced into the heating cavity H, and the argon atmosphere is restored. The loader 333 is then lowered by the crane. After the crucible 200 is cooled down together with the anhydrous rare earth chloride product therein, an operator can manually transfer the crucible 200 containing the anhydrous rare earth chloride product to the table 53 through the glove box operation port 55, and perform operations such as packaging. Finally, the second sealing door 57 is opened, and the packaged anhydrous rare earth chloride product can be taken out from the material taking opening R.

In this way, the rare earth chloride crystal raw material is carried out in a relatively closed environment in the whole process of drying and packaging to obtain the packaged anhydrous rare earth chloride product. The transfer of the anhydrous rare earth chloride product among the heating device 10, the feeding device 30 and the operating device 50, and also the continuous transfer of the material dehydration and operating system 100, can obviously reduce the possibility of the contact of the anhydrous rare earth chloride product with air, and ensures the quality of the packaged anhydrous rare earth chloride product.
