[0027] Among them, a cooling cavity 5 is arranged around the refining cavity 4 in the furnace body 1. The top of the cooling cavity 5 is open and located at the edge of the upper end face of the furnace body 1. One side of the top of the cooling cavity 5 is connected with a water inlet pipe 6, and one side of the bottom of the cooling cavity 5 is connected with a water outlet pipe 7. A cooling component 8 surrounding the refining cavity 4 is placed in the cooling cavity 5, so that the cooling component 8 can be used to cool down in the cooling cavity 5.

[0028] Specific cooperation Figure 3 As shown, the cooling component 8 includes a water receiving ring 801, an upper ring pipe 805, a cooling pipe 806 and a lower ring pipe 807. A water receiving groove 802 is arranged on the upper end face of the water receiving ring 801, which can be used to receive the water inlet from the water inlet pipe 6. A pull ring 803 is fixed on the upper end face of the water receiving ring 801, which can facilitate the overall extraction of the cooling component 8 from the cooling cavity 5. And a plurality of vertical water pipes 804 are fixed on the lower end face of the water receiving ring 801. The top end of the water pipe 804 is communicated with the inside of the water receiving groove 802, and the bottom end is communicated with the inside of the upper ring pipe 805, so as to fix the upper ring pipe 805 below the water receiving ring 801.

[0029] And a plurality of cooling pipes 806 are vertically installed on the lower end face of the upper ring pipe 805. The cooling pipe 806 is an S-shaped pipe rotating around the refining cavity 4. A lower ring pipe 807 is jointly installed at the lower ends of the plurality of cooling pipes 806. A plurality of water outlet holes 808 are arranged on the lower end face of the lower ring pipe 807, so that the cooling water can flow around the refining cavity 4 in the cooling pipe 806 to improve the cooling effect, and finally be discharged into the bottom of the cooling cavity 5 through the water outlet holes 808 and discharged through the water outlet pipe 7 to take out the heat.
