Generally, in the process of heating and mixing materials in a conventional vacuum stirring and refining system, due to different melting points of the materials, the material with a lower melting point is melted and located at the bottom of the crucible during the heating process, and is also sublimated and attached to the upper side wall of the crucible, wherein the upper side wall refers to the side wall part close to the mouth part. The material adhered to the upper side wall is not mixed with other molten materials because the material does not contact other materials, after the cooling step is carried out, the uniformly mixed material in the crucible is cooled to become solid, and the material adhered to the upper side wall of the crucible is also cooled to become solid. On the one hand, the material of misce bene in the crucible leads to each material quality of final mixed product to account for than to have great deviation with preset quality because of lacking the adnexed material of upper portion lateral wall department, and on the other hand, when taking out the material in the crucible, can inevitably take out the adnexed material on the lateral wall of upper portion jointly, because adnexed material quality accounts for than to have great deviation with preset quality on the lateral wall, lead to the material of whole mixed product inhomogeneous, and present product, especially among the organic electroluminescent device, require extremely high to the mixed material, the adnexed material of crucible upper portion lateral wall can lead to the material qualification rate after the mixture to hang down.

Referring to fig. 1 and 2, fig. 1 shows one of the operation state diagrams of the vacuum stirring and refining system in the first embodiment of the present invention, and fig. 2 shows another operation state diagram of the vacuum stirring and refining system in the first embodiment of the present invention.

In the vacuum stirring and refining system, during operation, a plurality of materials with specific mass ratio are filled into the container 10, for example, the amount of the materials filled into the container 10 is not more than three-fourths of the volume of the chamber 12 of the container 10, the container 10 is vacuumized by the vacuum pump 40 to provide a vacuum environment, the container 10 is heated by the heating element 20 to melt the materials in the container 10, and the materials in the container 10 are stirred by the stirring device 50 to uniformly mix the materials. The driving device 60 can drive the machine shell 30 to move, when the machine shell 30 moves, the melted material in the container 10 infiltrates the inner side wall of the container 10, when the melted material infiltrates the inner side wall of the container 10, the material attached to the inner side wall of the container 10 is fully mixed with other materials, so that the deviation of the mass proportion of each material in the finally obtained mixed product to the preset mass proportion is small, and the qualified rate of the mixed product is high.

In this embodiment, the material is an organic small molecule material. For example, the difference in melting points between the various materials does not exceed 30 ℃. Further, the difference of melting points among various materials is not more than 10 ℃. Too large a difference in melting point between the various materials may result in sublimation of the materials having a lower melting point, thereby affecting the quality ratio of the blended product.

Referring to fig. 1 and fig. 2, further, the driving device 60 includes a rotating mechanism 61 and an inclination adjusting mechanism 62. The inclination adjusting mechanism 62 is mounted on the rotating mechanism 61.

Thus, the rotating mechanism 61 drives the supporting plate 622 to rotate, and the supporting plate 622 drives the bottom plate 623 to rotate. When the bottom plate 623 rotates, the bottom plate 623 slides relative to the pressing mechanism 625. The pressing portion of the pressing mechanism 625 and the supporting plate 622 is in sliding contact with and matches with the supporting plate 622, and the pressing mechanism 625 may be specifically disposed on the ground, a workbench, or the like, and does not rotate with the bottom plate 623 and the casing 30.

Thus, when the rotating mechanism 61 drives the casing 30 to rotate, the casing 30 synchronously rotates the obliquely arranged container 10 correspondingly, and when the obliquely arranged container 10 rotates, the material in the molten state in the container 10 can infiltrate into the material on the inner side wall of the container 10 and is fully and uniformly mixed with the material.

Further, referring to fig. 1 and fig. 2, the housing 30 is provided with a viewing port. So, the viewing aperture is used for observing material state and crucible inclination in the crucible, prevents that the material from spilling over the crucible. The position of the viewing port on the housing 30 may be arbitrarily set, and for example, the viewing port may be a top wall of the housing 30 or a side wall of the housing 30, as long as the state of the material in the crucible and the inclination angle of the crucible can be observed through the viewing port.

Further, a fixing member for fixing the container 10 is provided in the chamber 12. In this manner, the securing member secures the container 10 within the chamber 12 and prevents the container 10 from wobbling when tilted.

Further, the vacuum stirring and refining system also comprises an insulating layer 70. The insulation layer 70 wraps the outer side wall of the chamber 12. The heat-insulating layer 70 plays a role in heat insulation of the chamber 12, so that energy loss in the heating process of the heating element 20 is avoided, and the material in the container 10 is melted and uniformly mixed.

In one embodiment, referring to fig. 1 and fig. 2 again, a refining method using the vacuum stirring refining system according to any of the above embodiments includes the following steps:

providing materials with a preset mass ratio, and filling the materials into a container 10;

wherein the container 10 is filled with a quantity of material not exceeding three quarters of the volume of the chamber 12 of the container 10.

Vacuumizing the container 10 to provide a vacuum environment, and heating the container 10 by the heating element 20 to enable the materials in the container 10 to be in a molten state;

stirring the materials in the container 10 to uniformly mix the materials;

and driving the machine shell 30 to act, wherein the machine shell 30 acts to enable the material in the molten state in the container 10 to infiltrate the inner side wall of the container 10.

When the material in the molten state wets the inner side wall of the container 10, the material adhered to the inner side wall of the container 10 is fully mixed with other materials.

In the refining method of the vacuum stirring refining system, the material in the melting state in the container 10 infiltrates the inner side wall of the container 10, and the material attached to the inner side wall of the container 10 is fully mixed with other materials when the material in the melting state infiltrates the inner side wall of the container 10, so that the deviation of the mass ratio of each material in the finally obtained mixed product to the preset mass ratio is small, and the qualified rate of the mixed product is high.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
