Description

Technical Field

[0001] The present invention belongs to the technical field of copper smelting, and particularly relates to a tuyere composite brick. Background Art

[0002] The interior of the metal shell of the anode furnace for pyrometallurgical copper smelting needs to be lined with refractory materials, and the laying quality of the refractory materials directly affects the service life of the anode furnace. The tuyeres of the anode furnace are used frequently, resulting in rapid wear of the lining bricks at the tuyere. When the erosion of the lining bricks at the tuyere is too large, the molten liquid may flow out from the tuyere, seriously affecting production safety and requiring the furnace to be shut down for maintenance. The removal and laying of the bricks in the tuyere area are inconvenient, making the repair difficult and the operation time long, affecting production efficiency. Frequent repairs will also damage the surrounding lining bricks, thus affecting the safety of the furnace body. Summary of the Invention

[0004] To achieve the above purpose, the technical solution adopted by the present invention is: a tuyere composite brick, in which air guiding holes for introducing air flow from top to bottom and from outside to inside are provided on adjacent bricks, the extending direction of the air guiding holes is arranged at an angle with the inner end surface of the brick, the air guiding holes include an air inlet section located in the air inlet brick and an air outlet section located in the air outlet brick, and the air outlet port of the air guiding hole is located at the lower part of the inner end surface of the air outlet brick.

[0005] Compared with the prior art, the present invention has the following technical effects: the integrity of the inner side of the air outlet brick body is good, and the molten liquid erosion resistance performance is high, so as to effectively extend the service life of the air outlet brick, reduce the repair times at the tuyere, and significantly improve the production efficiency.

[0012] The specific implementation of the present invention is further described in detail below through description of embodiments in conjunction with the accompanying drawings.

[0013] A tuyere combination brick, wherein adjacently arranged brick bodies are provided with air guide holes 10 for introducing airflow from top to bottom and from outside to inside, the extension direction of the air guide holes 10 is arranged at an angle with the inner end surface of the brick body, the air guide holes 10 include an air inlet section 11 located in the air inlet brick 20 and an air outlet section 12 located in the air outlet brick 30, and the air outlet port of the air guide hole 10 is located at the lower part of the inner end surface of the air outlet brick 30.

[0014] The outer end of the tuyere combined brick is matched with the metal shell of the anode furnace A, and the inner end forms a cavity for the molten liquid. The air outlet port of the air guide hole 10 is arranged at the lower part of the inner end surface of the air outlet brick 30, so that the inner brick body of the air outlet brick 30 has good integrity, is resistant to molten liquid erosion, and has a significantly extended service life.

[0015] When the tuyere combination bricks are built in the anode furnace A, Figure 1 , 2 As shown, the brick body is defined as the horizontal direction when it is in radial direction with the anode furnace A, the vertical direction when it is in axial direction with the anode furnace A, and the vertical direction when it is in circumferential direction with the anode furnace A. The brick body of the tuyere combination brick includes the inner and outer end faces at both ends of the horizontal direction, the front and rear side faces at both ends of the longitudinal direction, and the upper and lower side faces at both ends of the vertical direction.

[0016] In the preferred embodiment, the distance between the upper edge of the outlet port of the air outlet section 12 and the upper edge of the inner end surface of the air outlet brick 30 is greater than the circumferential dimension of the inner end surface of the air outlet brick 30 in the anode furnace A. Attached Figure 2 The d1 is greater than the vertical dimension of the inner end surface of the air outlet brick 30. When the air inlet section 11 is directly connected to the air outlet section 12, as shown in the attached Figure 3 , 4 As shown, the distance between the inner edge of the air inlet port of the air outlet section 12 and the inner edge of the surface where it is located is greater than the radial dimension of the surface in the anode furnace A. Attached Figure 2 The d2 is greater than the horizontal dimension of the upper side of the air outlet brick 30. When the air inlet section 11 and the air outlet section 12 are transitionally connected, as shown in the attached Figure 5 , 6 As shown, the distance between the inner edge of the outlet port of the air inlet section 11 and the inner edge of the surface where it is located is greater than the radial dimension of the surface in the anode furnace A. Attached Figure 6 The middle d4 is larger than the horizontal dimension of the lower side of the air inlet brick 20 In this way, the inner end face of the air outlet brick 30 located in the upper block of the air outlet section 12 is larger and the volume is larger, and the connection with the adjacent blocks is more compact and reliable, so as to prevent the inner block of the air outlet brick 30 from falling off and causing the molten liquid to flow out from the air guiding hole 10.

[0017] In the preferred solution, the distance between the upper edge of the air inlet port of the air inlet section 11 and the upper edge of the outer end face of the air inlet brick 20 is greater than i.e., attached Figure 2 in which d3 is greater than This makes the block adjacent to the inner side of the anode furnace of the air inlet brick 20 larger, thus ensuring the reliability of the molten liquid cavity.

[0018] As shown in the attachment Figure 3 for Example 1, the core of the air guiding hole 10 is perpendicular to the rotation center of the anode furnace A.

[0019] As shown in the attachment Figure 3 , 4 , 5, the air outlet port of the air guiding hole 10 is centrally arranged in the axial direction of the anode furnace A on the inner end face of the air outlet brick 30. In this way, the distances between the two side edges of the air outlet port of the air guiding hole 10 and its adjacent side edges are equal.

[0020] In this embodiment, as Figure 2 shown, the cross-section of each combined brick body in the direction perpendicular to the axial direction of the anode furnace A is integrally trapezoidal with a large outer side and a small inner side. Further as Figure 3-5 shown, each combined brick body is a block integrally in the shape of a trapezoidal column.
