DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] The present utility model provides an industrial silicon superconducting waterless burner as shown in Figures 1 - 4 , which includes an upper connecting member 1 and a lower connecting member 2. Installation plates 3 are fixedly installed at the ends of the upper connecting member 1 and the lower connecting member 2 that are close to each other. The upper connecting member 1 and the lower connecting member 2 are connected to each other through the installation plates 3. An I-shaped suspension arm 4 is connected to the lower connecting member 2. A burner electrode 5 is provided at the bottom of the I-shaped suspension arm 4. A fixed neck sleeve 6 is provided outside the burner electrode 5. The number of the fixed neck sleeves 6 is two. The top of one of the fixed neck sleeves 6 is fixedly installed at the bottom of the I-shaped suspension arm 4. The two fixed neck sleeves 6 are connected by screws 9 and nuts 10. Copper bushings 7 are fixedly installed on the inner walls of the two fixed neck sleeves 6. A peak blocking plate 8 is connected to one side of the fixed neck sleeve 6. One end of the burner electrode 5 movably penetrates through the peak blocking plate 8.

[0021] Please refer to Figures 1 - 2 . First, align the upper connecting member 1 and the lower connecting member 2 so that they are closely attached to the installation plate 3 and are fixedly connected through the installation plate 3. Install the I-shaped suspension arm 4 on the lower connecting member 2 to ensure that the I-shaped suspension arm 4 can stably bear the weight of the burner electrode 5 and various acting forces generated during operation. Fix one of the fixed neck sleeves 6 at the bottom of the I-shaped suspension arm 4. Install copper bushings 7 on the inner walls of the two fixed neck sleeves 6 respectively, which can provide good electrical conductivity and support for the burner electrode 5. Insert the burner electrode 5 into the two fixed neck sleeves 6 so that the outside of the burner electrode 5 is in close contact with the copper bushings 7 to ensure good electrical conductivity. At the same time, adjust the position of the burner electrode 5 so that one of its ends can movably penetrate through the peak blocking plate 8. When it is necessary to perform a piercing operation on industrial silicon, the burner electrode 5 is aligned with the tapping hole of the industrial silicon furnace. The current is conducted to the burner electrode 5 through the copper bushings 7. Due to the good electrical conductivity and high temperature resistance of the burner electrode 5, a high-temperature arc will be generated at the end of the burner electrode 5 under the action of the current. The high-temperature arc can quickly melt and pierce the substances at the tapping hole of the industrial silicon furnace, enabling the liquid industrial silicon in the furnace to flow out smoothly. During this process, the peak blocking plate 8 plays a role in limiting the peak value of overvoltage, protecting the burner electrode 5 and other components from being damaged by excessive voltage. The superconducting waterless design avoids the problem that traditional burners require a large amount of water resources for cooling. This not only saves water resources, reduces the impact on the environment, but also reduces the water consumption cost of enterprises.

[0022] A high-temperature resistant insulating plate 11 is fixedly installed between two mounting plates 3. A screw 9 is arranged between the two mounting plates 3, and a nut 10 is threadedly installed on the screw 9;

[0023] Please refer to Figures 3 - 4 , place the high-temperature resistant insulating plate 11 between the two mounting plates 3, ensure its accurate position, and effectively isolate the upper connecting piece 1 and the lower connecting piece 2 to prevent current leakage and short circuit.

[0024] One end of the piercing electrode 5 is fixedly installed with a pure copper tube 14. The number of pure copper tubes 14 is two. The bottom of the lower connecting piece 2 is fixedly installed with a red copper bus bar 15. A wire 16 is connected to the red copper bus bar 15. The number of wires 16 is two. One end of each wire 16 is electrically connected to the pure copper tube 14 respectively. A bus bar 12 is connected to the red copper bus bar 15, and the bus bar 12 is electrically connected to an external power supply;

[0025] Please refer to Figure 1 , Figure 3 , fix the red copper bus bar 15 to the bottom of the lower connecting piece 2 by means of bolts or welding, etc. Electrically connect one end of the bus bar 12 to an external power supply to provide electric energy. Connect the pure copper tube 14 on the piercing electrode 5 to the wire 16 to ensure reliable connection and good electrical conductivity, so as to enable the piercing electrode 5 to work normally.

[0026] The working principle of the present utility model: Align the upper connecting piece 1 and the lower connecting piece 2 so that they are closely attached to the mounting plate 3 and fixedly connected through the mounting plate 3. Install the I-shaped cantilever 4 on the lower connecting piece 2 to ensure that the I-shaped cantilever 4 can stably bear the weight of the piercing electrode 5 and various acting forces generated during work. Fix one of the fixed neck sleeves 6 at the bottom of the I-shaped cantilever 4. Install copper bushings 7 on the inner walls of the two fixed neck sleeves 6 respectively, which can provide good electrical conductivity and support for the piercing electrode 5. Insert the piercing electrode 5 into the two fixed neck sleeves 6 so that the outside of the piercing electrode 5 is in close contact with the copper bushing 7 to ensure good electrical conductivity. At the same time, adjust the position of the piercing electrode 5 so that one end of it can movably penetrate the peak blocking plate 8. When it is necessary to perform a piercing operation on industrial silicon, the piercing electrode 5 is aligned with the tapping hole of the industrial silicon furnace. The current is conducted to the piercing electrode 5 through the copper bushing 7. Due to the good electrical conductivity and high-temperature resistance of the piercing electrode 5, under the action of the current, a high-temperature arc will be generated at the end of the piercing electrode 5. The high-temperature arc can quickly melt and burn through the substances at the tapping hole of the industrial silicon furnace, enabling the liquid industrial silicon in the furnace to flow out smoothly. In this process, the peak blocking plate 8 plays a role in limiting the peak value of overvoltage, protecting the piercing electrode 5 and other components from being damaged by excessive voltage. The superconducting water-cooled-free design avoids the problem that traditional piercers require a large amount of water resources for cooling. This not only saves water resources, reduces the impact on the environment, but also reduces the water consumption cost of enterprises.
