Multiple groups of gears 66 are respectively located in the four groups of trapezoidal grooves 14, and the multiple groups of gears 66 are respectively engaged with the second rack 53.

[0048] Basic principles of the present invention:

[0049] The rotating plate 43 and the ring 50 of the present invention move up and down to drive the rack 1 46 and the rack 2 53 to move up and down, thereby rotating the gear 1 62 and the gear 2 66, so that the first stirring plate 60 is rotated on the one hand, and the second stirring plate 63 is moved while rotating at the same angular velocity and direction as the first stirring plate 60 through the cooperation of the screw 2 65 and the screw hole 16, wherein the width of the rack 2 53 is twice the moving distance of the second stirring plate 63, so that the present invention can control the state of the combination of the first stirring plate 60 and the second stirring plate 63 through the hydraulic cylinder 24;

[0050] like Figure 1 As shown, it is the state of the present invention before starting to feed, the rotating plate 43 is located above the stirring shaft cover plate 40, the ring 50 is located in the same plane as the rotating plate 43, and the feed cover plate 292 covers the feed port 26;

[0051] like Figure 2 , Figure 5 As shown, the driving motor 28 drives the screw 282 to rotate and then drives the feed cover plate 292 to slide along the baffle 27, and then the worker puts the raw material into the feed port 26, and the raw material falls from the feed port 26 to the spiral slide composed of the first stirring plate 60 and the second stirring plate 63, and then falls onto the inner bottom surface 12. During this process, the eight groups of inner walls 11 of the base 10 and the heating wires inside the first stirring plate 60 and the second stirring plate 63 will heat up, turning the tellurium raw material into liquid, and then the driving motor 28 drives the screw 282 to rotate in the opposite direction, so that the feed cover plate 292 slides in the opposite direction along the baffle 27 to seal;

[0052] like Figure 3 , Figure 6As shown, at this time, the tellurium raw material has been turned into a liquid state, and then the four groups of hydraulic cylinders 24 drive the ring 50 to move downward along the positioning bar 23, and the ring 50 drives the four groups of extended plates 44 to move downward, and then drives the rotating plate 43 to move downward along the arc-shaped positioning plate 42, so that the four groups of racks 1 46 at the lower end of the rotating plate 43 and the four groups of racks 2 53 at the lower end of the ring 50 move downward synchronously. Since the rack 1 46 is meshed with the gear 1 62, and the rack 2 53 is meshed with the gear 2 66, the multiple groups of gears 1 62 and gears 2 66 rotate synchronously, and the rotation of the rotating plate 43 is performed. The rotation shaft 1 61 is rotated synchronously with the inner end 64 of the second rotation shaft, the second screw 65, and the outer end 67 of the second rotation shaft. The rotation of the first rotation shaft 61 causes the first stirring plate 60 to rotate to a horizontal state. The inner end 64 of the second rotation shaft, the second screw 65, and the second rotation shaft rotate. Due to the cooperation of the screw hole 16 and the second screw 65, the inner end 64 of the second rotation shaft, the second screw 65, and the second rotation shaft rotate while moving. The second stirring plate 63 will move outward while performing the same rotation as the first stirring plate 60 to a horizontal state. At this time, the state is as follows Figure 6 As shown, the rotating motor 251 is then started to drive the bevel gear 1 252 to rotate and then drive the bevel gear 2 32 to rotate, so that the stirring shaft 30 drives the eight sets of side walls 31 and the first stirring plate 60 to rotate, thereby stirring the tellurium stock solution. Since the second stirring plate 63 does not move, the stirring is more efficient.

[0053] During the stirring process, the vaporized high-concentration tellurium will be heated and discharged from the outlet 211 to the condensation collection device externally connected to the outlet 211, and the high-concentration tellurium material will be collected according to the condensation principle;

[0054] When the stirring is completed, the driving motor 28 drives the screw 282 to rotate and then drives the feed cover 292 to slide along the baffle 27. Then the worker extends the suction pipe into the base 10 to suck out the remaining crude liquid tellurium. After the suction is complete, the hydraulic cylinder 24 moves in the reverse direction, so that the state of the present invention is restored to the state as shown in FIG. Figure 2 , Figure 5 In the state shown, the next filler purification work is carried out.

[0055] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
