Description

Technical Field

[0001] This utility model relates to the field of metallurgical technology, and in particular to a tuyere repair device for copper metallurgical converters. Background Technology

[0002] In copper metallurgical converters, the tuyere lining is frequently cleared using a tuyere clearing machine during production to prevent blockage and ensure stable air supply pressure. The tuyere lining is constantly subjected to mechanical vibrations from the clearing process, scouring by high-temperature molten metal, and chemical corrosion, making the bricks prone to damage. Current methods for repairing tuyeres typically involve workers manually approaching the high-temperature furnace opening and throwing sealed refractory bags onto the damaged bricks in the tuyere area. This requires workers to physically penetrate the tuyere to throw the refractory bags while enduring the high temperatures at the furnace opening, reducing repair efficiency and increasing safety hazards. Therefore, improvements are needed. Utility Model Content

[0030] The following is for reference. Figures 1-3 Description of an eyelet repair device 100 for a copper metallurgical converter according to an embodiment of the present invention.

[0031] like Figures 1-3As shown, the tuyere repair device 100 for a copper metallurgical converter according to an embodiment of the present invention includes a heat insulation component 10 and a feeding component 20. The heat insulation component 10 may include a transparent observation window 11, which allows the operator to observe the location and repair status of the damaged furnace bricks in real time through the observation window 11, so as to facilitate the operator's operation of the tuyere repair device 100, which is beneficial to improve the repair efficiency of the damaged furnace bricks. At the same time, it can isolate the copper metallurgical converter from the operator, which can prevent the operator from being burned by the copper metallurgical converter and reduce the safety hazards of furnace brick repair.

[0032] The heat insulation component 10 may define a support opening 16, which may be located on the outer periphery of the observation window 11. The feeding component 20 may include a movable rod 21 and a feeding box 22. The movable rod 21 may pass through the support opening 16, which can support the movable rod 21. That is, the inner edge of the support opening 16 can serve as a fulcrum, and the movable rod 21 can act as a lever, thereby driving the other end of the movable rod 21 (e.g., Figure 1 The movement of the front end shown can drive one end of the movable rod 21 (such as...) Figure 1 The rear-end movement shown makes it easier for the operator to control the movable lever 21, allows for more precise control, and facilitates operation.

[0033] Feed box 22 can be connected to one end of movable rod 21 (e.g. Figure 1 The feeding box 22 (as shown at the rear end) is connected to a feeding chamber 221, which can be filled with refractory material. One side of the feeding chamber 221 is open, allowing the feeding box 22 to be connected to the other end of the movable rod 21 (e.g., the rear end of the rod). Figure 1 The front end shown is active during operation, allowing it to extend into the copper metallurgical converter through the tuyere and pour refractory material onto the damaged brick lining area at the tuyere to repair the damaged furnace bricks. This allows for precise control of the position of the feeding box 22, improving the efficiency and effectiveness of repairing damaged furnace bricks. It also increases the distance between the operator and the copper metallurgical converter, reducing safety hazards during furnace brick repair.

[0034] According to the embodiment of the present invention, the tuyere repair device 100 for a copper metallurgical converter, by setting a heat insulation component 10 and a movable rod 21 that can be inserted into and supported on the heat insulation component 10, can isolate the copper metallurgical converter from the operator and increase the distance between the operator and the copper metallurgical converter, thus preventing the operator from being burned by the copper metallurgical converter. At the same time, it makes it easier and more precise for the operator to operate the movable rod 21, and can achieve precise control of the position of the feeding box 22, thereby improving the repair efficiency and effect of damaged furnace bricks and reducing the safety hazards of furnace brick repair.

[0035] Furthermore, compared to the method of operators throwing refractory materials onto damaged furnace bricks, by setting a feeding box 22 that can be opened on one side at the end of the movable rod 21, the distance between the operator and the copper metallurgical converter can be increased, which can prevent the operator from being burned by the copper metallurgical converter. It also allows the feeding box 22 to pour refractory materials to repair damaged furnace bricks, which can prevent refractory materials from splashing due to excessive movement speed, reduce the number of times damaged furnace bricks need to be repaired, and improve the utilization rate of refractory materials. For example, the utilization rate of refractory materials can be increased by 40%, and the repair efficiency and repair effect of damaged furnace bricks can be improved. For example, the repair efficiency can be increased by 50%, while reducing the safety hazards of furnace brick repair.

[0036] It should be added that, compared to the method where the operator holds the end of the movable rod 21 and lifts the entire movable rod 21, by supporting the movable rod 21 on the heat insulation component 10, the operator can operate the movable rod 21 with less effort and more precision. This allows for precise control of the position of the feeding box 22 and improves the efficiency and effect of repairing damaged furnace bricks.

[0037] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the heat insulation component 10 may further include a heat insulation frame 12, which may define an observation port, an observation window 11 may be disposed within the observation port, and a support port 16 may be located on the outer periphery of the heat insulation frame 12. This can prevent the movable rod 21 from interfering with the operator's line of sight. Based on ensuring that the operator can operate the movable rod 21 more effortlessly, the location and repair status of the damaged furnace bricks can be observed more clearly, and the position of the feeding box 22 can be precisely controlled, thereby improving the repair efficiency of the damaged furnace bricks.

[0038] like Figure 1 and Figure 2 As shown, in some embodiments, the thermal insulation assembly 10 may further include a support beam 13, a first support 14, and a second support 15, wherein the first support 14 and the second support 15 may be disposed on one side of the thermal insulation frame 12 (e.g., Figure 1 The lower edge (as shown) can support the heat insulation frame 12, prevent the heat insulation frame 12 from tipping over or shaking when the air hole repair device 100 is working, improve the stability of the air hole repair device 100, and enable the operator to control the movable rod 21 more precisely, achieve precise control of the position of the feeding box 22, and improve the repair efficiency of the broken furnace bricks.

[0039] The support beam 13 can be set between the first support 14 and the second support 15, and the support beam 13 can be connected to the first support 14 and the second support 15 respectively. The support beam 13 and the heat insulation frame 12 can cooperate to form a support opening 16. That is, the support beam 13 can serve as a support for the movable rod 21 on one side edge of the support opening 16, which can improve the support effect of the movable rod 21, make it easier for the operator to operate the movable rod 21, and make the operator's operation of the movable rod 21 more precise. It can achieve precise control of the position of the feeding box 22 and improve the repair efficiency of damaged furnace bricks.

[0040] like Figure 1 and Figure 2 As shown, in some embodiments, the eyelet repair device 100 may further include a support base 30, the heat insulation component 10 may be mounted on the support base 30, and the first support 14 and the second support 15 may be disposed on the side of the heat insulation frame 12 near the support base 30 (e.g., Figure 1 (as shown on the lower side), so that the heat insulation component 10 can be supported on the support base 30 by the first support 14 and the second support 15, which can increase the height of the heat insulation component 10 and make it easier for the operator to operate the wind eye repair device 100.

[0041] The first support 14 can be connected to the support base 30 to connect the heat insulation component 10 and the support base 30, which can improve the stability of the support base 30 in supporting the heat insulation component 10 and improve the working stability of the vent repair device 100. Alternatively, the second support 15 can be connected to the support base 30 to connect the heat insulation component 10 and the support base 30. Or, the first support 14 and the second support 15 can be connected to the support base 30 respectively, which can improve the connection effect between the heat insulation component 10 and the support base 30, improve the stability of the support base 30 in supporting the heat insulation component 10, improve the working stability of the vent repair device 100, thereby improving the operator's precision in controlling the movable rod 21, enabling precise control of the position of the feeding box 22, and improving the repair efficiency of damaged furnace bricks.

[0042] like Figure 1 , Figure 2 and Figure 3As shown, in some embodiments, the support base 30 may include a mounting beam 31, the first support 14 may have a mounting portion 17, and the first support 14 may be connected to the mounting beam 31 through the mounting portion 17 to connect the heat insulation component 10 to the support base 30; or, the second support 15 may have a mounting portion 17, and the second support 15 may be connected to the mounting beam 31 through the mounting portion 17 to connect the heat insulation component 10 to the support base 30; or, the first support 14 and the second support 15 may each have a mounting portion 17, and the first support 14 and the second support 15 may each be connected to the mounting beam 31 through mounting bases, which can improve the connection effect between the heat insulation component 10 and the support base 30, improve the stability of the support base 30 in supporting the heat insulation component 10, and improve the working stability of the vent repair device 100.

[0043] The mounting section 17 may include a connecting rod 171 and two mounting rods 172. The two mounting rods 172 may be arranged at intervals, and the two mounting rods 172 may be positioned in directions away from the heat insulation frame 12 (e.g., Figure 3 Extending in the direction shown from top to bottom, the connecting rod 171 can be connected to two mounting rods 172 respectively, and the connecting rod 171 and the two mounting rods 172 cooperate to form a mounting opening 173. The mounting beam 31 can pass through the mounting opening 173, which can lock the mounting part 17 onto the mounting beam 31. The mounting beam 31 can contact the connecting rod 171 and the mounting rod 172 respectively, which can improve the locking effect on the mounting part 17, thereby improving the connection effect between the heat insulation component 10 and the support base 30, improving the stability of the support for the heat insulation component 10, preventing the heat insulation component 10 from tipping over or shaking when the wind eye repair device 100 is working, and improving the working stability of the wind eye repair device 100.

[0044] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the support base 30 may include a mounting beam 31 and two support frames 32. The two support frames 32 may be arranged at intervals, and the mounting beam 31 may be disposed between the two support frames 32. The mounting beam 31 may be connected to the two support frames 32 respectively, so that the support base 30 can be supported on the ground by the two support frames 32, which can improve the structural strength and stability of the support base 30. The heat insulation frame 12 may be connected to the mounting beam 31 through the mounting part 17, thereby improving the stability of the support for the heat insulation component 10 and preventing the heat insulation component 10 from tipping over or shaking when the wind eye repair device 100 is working, thus improving the working stability of the wind eye repair device 100.

[0045] The number of mounting beams 31 can be one, which can ensure the structural strength of the support base 30, ensure the support effect of the heat insulation component 10, and reduce costs. Alternatively, the number of mounting beams 31 can be multiple. The heat insulation frame 12 can be connected to the mounting beam 31 closest to the heat insulation frame 12 through the mounting part 17. This can prevent the movable rod 21 from interfering with the support base 30, prevent the support base 30 from interfering with the operator's line of sight, improve the structural strength of the support base 30, improve the stability of the support base 30, improve the stability of the support for the heat insulation component 10, and improve the working stability of the air hole repair device 100. This can achieve precise control of the position of the feeding box 22 and improve the repair efficiency and repair effect of the damaged furnace bricks.

[0046] like Figure 1 and Figure 2 As shown, in some embodiments, the support frame 32 can be a triangular bracket, which can improve the structural strength of the support frame 32, increase the service life of the support frame 32, facilitate maintenance, and improve the stability of the support base 30. It can prevent the heat insulation component 10 from tipping over or shaking when the air hole repair device 100 is working, thereby improving the working stability of the air hole repair device 100. This can also improve the working stability of the air hole repair device 100, enable precise control of the position of the feeding box 22, and improve the repair efficiency and repair effect of the damaged furnace bricks.

[0047] like Figure 1 and Figure 2 As shown, in some embodiments, the support beam 13 can be a circular column beam, which can ensure that the movable rod 21 is always supported on the arc surface of the side wall of the circular column beam during movement. This can prevent the movable rod 21 from breaking due to excessive force between the support beam 13 and the movable rod 21, allowing the movable rod 21 to withstand faster movement speeds and enabling the feeding box 22 to carry a larger mass of refractory material. This can improve the repair efficiency and effect of damaged furnace bricks, facilitate operation, and extend the service life of the movable rod 21, making maintenance easier.

[0048] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the other end of the movable rod 21 (e.g.) Figure 1 The front end shown can be provided with multiple grip levers 211. One end of each grip lever 211 can be connected to the movable rod 21. The multiple grip levers 211 can be arranged circumferentially around the movable rod 21. Each grip lever 211 can extend in a direction perpendicular to the extension direction of the movable rod 21, which is convenient for the operator to grip and for the operator to drive the multiple grip levers 211 to move circumferentially around the movable rod 21 to drive the entire movable rod 21 to rotate, so that the feeding box 22 can pour out refractory materials, which is convenient for operation.

[0049] According to some embodiments of this utility model, the observation window 11 can be heat-resistant glass, which can be borosilicate glass, quartz glass (fused silica), or aluminosilicate glass, etc. The heat-resistant glass can be a multi-layer structure, and adjacent layers can be arranged alternately to be vacuumed or filled with inert gas. The surface of the heat-resistant glass can be coated with a low-emissivity coating such as SnO, Ag, or ITO film, which can improve the heat insulation effect of the heat insulation component 10, thereby preventing operators from being burned by copper metallurgical converters, reducing the safety hazards of furnace brick repair, and facilitating operators to observe the location and repair status of damaged furnace bricks in real time, thereby improving the repair efficiency of damaged furnace bricks.

[0050] According to some embodiments of this utility model, the refractory material can be refractory mortar (refractory putty), refractory castable, phosphate binder or silicon carbide based material, etc. By throwing or pouring the above-mentioned refractory material into the damaged area of ​​the brick lining at the vent, the damaged furnace bricks can be repaired, which is convenient for operation.
