[0038] Working principle;

[0039] Firstly, the zinc ingot is placed in the inner cavity of the crucible inner furnace 103, and the crucible inner furnace 103 is placed in the crucible outer furnace 102, and the mouth of the crucible inner furnace 103 is closed by using the furnace cover 104, then, at the same time, the two groups of shells 300 are turned inward, so that the sealing plates 303 in the two groups of shells 300 abut against the corresponding side surfaces of the rotating ring 107 respectively, and the gap between the crucible inner furnace 103 and the crucible outer furnace 102 is sealed, so as to reduce the heat dissipation to the outside;

[0040] Then, the temperature parameters and the heating time are set through the operation screen 201, and the operation screen 201 sends a signal to the controller 200, so that the controller 200 controls the driving circuit of the electromagnetic heating pipe 101 to start, and the electromagnetic heating pipe 101 heats the crucible inner furnace 103;

[0041] And during the heating process, the furnace cover 104 can be rotated to drive the crucible inner furnace 103 to rotate, so that the crucible inner furnace 103 rotates and the zinc ingot is heated more uniformly, and at the same time, the rotating column 111 is driven to rotate by the rotating disc 110 during the rotation of the crucible inner furnace 103, so as to reduce the force required for rotating the crucible inner furnace 103;

[0042] When the sealing plate 303 is worn out after long-term use, the sealing degree between the sealing plate 303 and the crucible inner furnace 103 can be adjusted by rotating the hand-tightening bolt 301, the hand-tightening bolt 301 pushes the sealing plate 303 inward, so that the sealing plate 303 moves towards the crucible inner furnace 103 until the rotating ring 107 of the crucible inner furnace 103 is tightly fitted, and a good sealing effect is achieved;

[0043] When the sealing plate 303 is pushed to the required position, the limiting bolt 304 is inserted into the limiting hole 309 at the top of the shell 300, and then the end thereof is made to penetrate through the limiting hole 309 downward and is screwed into the first threaded hole 305 at the top of the sealing plate 303, the limiting bolt 304 is tightened so that the bottom surface of the head of the limiting bolt 304 contacts the surface of the shell 300, thereby firmly fixing the sealing plate 303 at the current position and preventing the sealing plate 303 from moving due to external force and other factors and affecting the sealing effect;

[0044] When the sealing plate 303 is worn out, the shell 300 is first turned outward so that the recess 302 faces upward, at this time, the two sets of guide rods 307 are loosened and the limiting bolt 304 is removed, and the guide rods 307 are pulled outward so as to be separated from the sealing plate 303, thereby releasing the limitation on the sealing plate 303, at this time, the sealing plate 303 is removed and a new sealing plate 303 is replaced, the two sets of guide rods 307 penetrate through the shell 300 and are screwed into the inner cavities of the corresponding second threaded holes 306 to preliminarily fix the sealing plate 303, finally, the limiting bolt 304 penetrates through the limiting hole 309 and is screwed into the inner cavity of the first threaded hole 305 to finally fix the sealing plate 303, thereby completing the replacement of the sealing plate 303.
