[0003] However, when the barrel is used for secondary feeding, the barrel is arranged above the crucible, and there is still a distance from the bottom end of the barrel to the bottom of the crucible. When the metal beryllium beads fall from the barrel, the beryllium beads collide with the molten beryllium liquid, thereby causing the metal to splash, and the beryllium beads collide with the inner wall of the crucible, thereby causing the inner lining of the crucible to be separated, resulting in damage to the crucible, affecting the service life of the crucible, and the separated inner lining of the crucible is melted into the metal beryllium liquid, thereby reducing the purity of the beryllium ingot.

[0027] In the embodiment, the mixing column 531 is a rhombus structure 532, and the mixing columns 531 are arranged in a circumferential staggered manner. Specifically, the diamond structure 532 of the mixing column 531 is used to enhance the shearing force on the metal beryllium beads and the molten beryllium liquid, thereby enhancing the stirring effect on the metal beryllium beads and the molten beryllium liquid, ensuring uniform mixing of the metal beryllium beads and the molten beryllium liquid, so that the metal beryllium beads are uniformly preheated. At the same time, the inclined surface of the diamond structure 532 will guide the metal beryllium beads to avoid sticking to the mixing column 531. The circumferential staggered arrangement of the mixing column 531 ensures the stirring area of the mixing column 531 while reducing the number of mixing columns 531, thereby avoiding the impact of too many mixing columns 531 on the discharging efficiency. At the same time, relative rotation may occur between the molten beryllium liquids guided by each mixing column 531, thereby enhancing the mixing effect of the metal beryllium beads and the molten beryllium liquid.

[0028] In this embodiment, the height of the mixing column 531 located outside the rotating plate 53 is greater than the height located inside the rotating plate 53. Specifically, the height of the mixing column 531 gradually decreases from the outer circumference of the rotating plate 53 to the inner circumference, thereby forming a spiral structure as a whole, and thereby enabling the mixing column 531 to guide the metal beryllium beads and the molten beryllium liquid to form a spiral structure when rotating, thereby enhancing the contact between the metal beryllium beads and the molten beryllium liquid. At the same time, when discharging is required, the mixing column 531 located on the inner circumference has a low height and has a small impact on discharging, thereby improving the efficiency and stability of discharging.

The telescopic shaft sleeve 71 is located at the bottom end of the driving shaft 51, and a telescopic groove 711 is formed in the telescopic shaft sleeve 71. The telescopic block 72 is slidably installed in the telescopic groove 711. The telescopic block 72 and the telescopic groove 711 are connected by the telescopic spring 73.

The positioning rod 75 is slidably installed in the rotating groove 742. The fixed table 76 is connected below the telescopic shaft sleeve 71. The fixed table 76 is provided with reciprocating blocks 761 arranged in an annular array. The discharging plate 8 is arranged above the fixed table 76. The discharging plate 8 is slidably installed in the driving shaft 51. The discharging plate 8 is provided with a reciprocating groove 81 matched with the reciprocating blocks 761. Specifically, the telescopic shaft sleeve 71 is located at the bottom end of the drive shaft 51, and the telescopic shaft sleeve 71 rotates synchronously with the drive shaft 51. The telescopic shaft sleeve 71 is provided with a telescopic groove 711, and the telescopic block 72 is slidably installed in the telescopic groove 711.

When the telescopic shaft sleeve 71 rotates synchronously with the drive shaft 51, the telescopic shaft sleeve 71 drives the telescopic block 72 to rotate synchronously through the telescopic spring 73, the telescopic block 72 drives the driving plate 74 to rotate synchronously by clamping into the clamping groove 741, and the driving plate 74 pushes and extrudes the positioning rod 75 through the rotating groove 742 when rotating, so that the positioning rod 75 slides horizontally along the circumferential outer side. The positioning rod 75 is in contact with the inner wall of the crucible, so as to realize the positioning of the material barrel 3, so that the material barrel 3 is located at the center position of the crucible, and sliding of the material barrel 3 under the action of the traction rope is avoided. Meanwhile, the material barrel 3 is located at the center of the crucible, so that the metal beryllium beads fall at the central axis of the crucible during discharging, and the melting efficiency of the metal beryllium beads is improved. The fixed table 76 is connected below the telescopic shaft sleeve 71, the reciprocating block 761 is annularly arranged on the fixed table 76, and the discharging plate 8 is arranged above the fixed table 76. The discharging plate 8 is slidably installed in the drive shaft 51, and the reciprocating groove 81 matched with the reciprocating block 761 is arranged at the lower end of the discharging plate 8. When the telescopic shaft sleeve 71 rotates, the fixed table 76 installed below the telescopic shaft sleeve 71 rotates synchronously, and the reciprocating groove 81 on the discharging plate 8 is extruded by the reciprocating groove 81 on the fixed table 76 when the fixed table 76 rotates, so as to push the discharging plate 8 to slide vertically upward. When the reciprocating block 761 is separated from the reciprocating groove 81, the discharging plate 8 slides downward under the impact of the metal beryllium beads and the molten beryllium liquid, and the reciprocating block 761 and the reciprocating groove 81 continue to engage, so as to realize the reciprocating movement of the discharging plate 8. The reciprocating movement of the discharging plate 8 dredges the discharge port 511 of the drive shaft 51, so as to avoid the bridging phenomenon in the discharge port 511, prevent the discharge port 511 from being blocked, and avoid the problems of affecting the discharging efficiency and the like.

[0030] In the embodiment, the telescopic block 72 is a regular triangle structure 721. Specifically, the telescopic block 72 is a regular triangle structure 721 for realizing the connection and separation between the driving plate 74 and the telescopic shaft sleeve 71.

At this time, the telescopic block 72 is pressed by the reaction force of the driving plate 74, the telescopic block 72 is gradually pressed by the inclined surface and the clamping groove 741, the telescopic block 72 is gradually pressed by the telescopic spring 73 and slides into the telescopic groove 711, and the telescopic shaft sleeve 71 is separated from the driving plate 74. When the driving motor 4 reverses, the telescopic shaft sleeve 71 drives the telescopic plate to reverse, the telescopic plate engages with the clamping groove 741, and then drives the driving plate 74 to reverse, and then drives the positioning rod 75 to reset. Since the driving plate 74 reverses to drive the positioning rod 75 to reset, at this time, the crucible no longer has a reaction force on the positioning rod 75. At this time, when the telescopic block 72 is clamped into the clamping groove 741, it will not slide into the telescopic groove 711 under the pressure of the inclined surface, but will drive the driving plate 74 to reverse together. When the positioning rod 75 is reset, the driving plate 74 is kept fixed, the telescopic block 72 is again pressed into the telescopic groove 711, and the telescopic shaft sleeve 71 is separated from the driving plate 74.

[0031] In the embodiment, the positioning rod 75 is provided with a positioning convex point at the middle end. Specifically, since the curvature of the positioning rod 75 is inconsistent with the curvature of the inner wall of the crucible, the positioning rod 75 cannot be completely attached to the inner wall of the crucible, and the positioning convex point is provided at the top end of the positioning rod 75. The positioning convex point is used to enhance the contact area between the positioning rod 75 and the crucible, and to enhance the friction between the crucible and the positioning rod 75, so as to ensure the stability of the contact between the positioning rod 75 and the crucible, and to ensure the center positioning effect of the material barrel 3.

[0032] In the embodiment, the discharging plate 8 is provided with a dredging block 82, and the lower end of the discharging plate 8 is provided with a cross-flow plate 83. Specifically, the dredging block 82 on the discharging plate 8 is used to enhance the dredging effect of the discharging plate 8 on the metal beryllium beads, to ensure the smoothness of the discharging port 511, and to avoid the blockage of the discharging port 511.
