[0023] The present invention will now be described in further detail with reference to the accompanying drawings.
[0024] Please refer to Figure 1 It can be seen that the original gas passages had four located on the gun core and five on the gun shroud. This combination resulted in a close contact between the gas passages and the oxygen delivery channel, making their ends extremely prone to burn-out. Please refer to [reference needed]. Figures 2-5 This invention proposes a combustion-supporting device for crude antimony smelting, comprising a first docking part and a second docking part detachably mounted on the first docking part. The second docking part includes a second gun core 6, on which a second gun sleeve 7 is fitted. A plurality of second gas passages 8 are formed on the second gun sleeve 7, evenly distributed around the perimeter of the second gun core 6. A second oxygen delivery channel 9 is formed inside the second gun core 6. The gas passages of this invention are all formed on the gun sleeve, effectively reducing the occurrence of burn-off.
[0025] The first docking part includes a first gun core 1, a first gun sleeve 2 is fitted on the first gun core 1, a plurality of first gas passage grooves 3 are opened on the first gun sleeve 2, the first gas passage grooves 3 are evenly distributed around the first gun core 1, and a first oxygen delivery channel 4 is opened inside the first gun core 1.
[0026] A first docking flange 5 is provided on the right side of the first gun shroud 2, and a second docking flange 10 is provided on the left side of the second gun shroud 7. The first gun shroud 2 and the second gun shroud 7 can be fixed together by the first docking flange 5 and the second docking flange 10. Even if the second docking part is damaged, it can be directly replaced, which reduces the cost of use.
[0027] A docking sleeve 11 is fixed at the right end of the second gun core 6. The docking sleeve 11 can be inserted into the first oxygen delivery channel 4. A docking block 12 is provided at the top of the docking sleeve 11. The docking block 12 is fixed at the right end of the second gun core 6. A docking groove 13 is opened at the left end of the first gun core 1 at a position opposite to the docking block 12.
[0028] A cooling sleeve 14 is fitted over the outside of the first gun shroud 2. The cooling sleeve 14 has a cooling water inlet and a cooling water outlet, and a pull-out bracket 15 is fixed to the outer wall of the cooling sleeve 14. In this embodiment, the cooling sleeve 14 fitted over the outside of the first gun shroud 2 cools this part and prevents it from overheating. Cooling water flows in through the cooling water inlet and is discharged through the cooling water outlet under the action of an external pump, thus achieving cooling of the first gun shroud 2.
[0029] Several gas inlet pipes 16 are distributed around the periphery of the first gun shroud 2, and a first control valve 17 is provided on each gas inlet pipe 16. An oxygen inlet pipe 18 is connected to the right end of the first gun core 1, and the oxygen inlet pipe 18 is connected to the first oxygen delivery channel 4. A second control valve 19 is provided on the oxygen inlet pipe 18. In this embodiment, the arrangement of multiple gas inlet pipes 16 can improve the gas delivery efficiency.
