Description

Technical Field

[0001] This utility model relates to the field of electrolytic aluminum combustion furnaces, and more specifically, to a burner angle adjustment mechanism. Background Technology

[0002] In the electrolytic aluminum smelting process, various combustion scenarios are required, from anode preheating to aluminum ingot melting. The combustion furnace can realize these combustion processes. Through a series of on-site verifications of the combustion and heating effects, it was found that the burner installation angle has a relatively significant impact on the heating effect. Adjusting the burner angle can, to a certain extent, increase the high-temperature flue gas and heat exchange intensity of the combustion flame, thereby affecting the required combustion time and effect. Currently, the burners in manufactured combustion furnaces are generally fixed to the side wall, and their angle cannot be or is inconvenient to adjust.

[0003] Utility model patent CN214065707U discloses a burner angle adjustment structure. An arc-shaped groove is provided at the burner opening in the furnace wall. An inner lining that matches the arc-shaped groove is cast on the inner wall of the burner near the furnace wall. Support plates are provided on both sides of the front end of the furnace wall, and a connecting plate is provided at the lower part of the burner. The connecting plate is positioned between the two support plates via a rotating shaft, allowing the burner to rotate along the rotating shaft. This burner angle adjustment structure connects the burner to the aluminum melting furnace wall via a rotating shaft, and the burner rotates along the rotating shaft. This rotating shaft installation method allows the burner angle to be adjusted according to changes in the liquid level, thereby ensuring the distance between the burner flame and the liquid surface, improving combustion thermal efficiency, and saving energy and reducing consumption. However, the disclosed burner angle adjustment structure requires modification of the burner structure and cannot be directly installed on the burner. Utility Model Content

[0004] In order to facilitate the adjustment of the burner angle of the combustion furnace without changing the burner structure, the technical solution adopted by this utility model is: a burner angle adjustment mechanism, which is installed on the outside of the combustion furnace shell and includes a burner mounting plate, wherein the combustion furnace shell is provided with an internal assembly hole;

[0005] The burner mounting plate is swayably disposed on the outside of the combustion furnace shell, used to install the combustion furnace burner and drive the combustion furnace burner to sway, so as to change the inclination angle of the inner end of the combustion furnace burner in the inner assembly hole.

[0006] Based on the above, the bottom of the burner mounting plate is rotatably connected to the outside of the combustion furnace shell.

[0007] Based on the above, in order to achieve smooth rotation, a rotating sleeve is provided at the bottom of the outer side of the combustion furnace shell, and a lower rotating shaft is provided at the bottom of the burner mounting plate. The bottom of the burner mounting plate is rotatably engaged with the rotating sleeve through the lower rotating shaft.

[0008] Based on the above, in order to ensure the stability of the oscillation process, a guide groove plate is provided on the top outer side of the combustion furnace shell. An arc-shaped guide groove is provided on the guide groove plate. An upper rotating shaft is provided on the top of the burner mounting plate. The end of the upper rotating shaft passes through the arc-shaped guide groove and is threaded with a nut. The nut is used to hold the upper rotating shaft on the guide groove plate.

[0009] Based on the above, the burner mounting plate is provided with an external mounting hole for the inner end of the combustion furnace burner to pass through, and the external mounting hole is arranged opposite to the internal mounting hole.

[0010] Based on the above, in order to facilitate the direct installation of the combustion furnace burner, the burner mounting plate is provided with fixing holes for connecting the combustion furnace burner, and the combustion furnace burner is installed on the burner mounting plate by fasteners.

[0011] Based on the above, the guide groove plate is arranged perpendicularly to the combustion furnace shell.

[0012] Based on the above, the rotating sleeve is arranged parallel to the combustion furnace shell.

[0013] Based on the above, in order to provide smooth guidance during the swinging process, the center of the arc of the arc-shaped guide groove coincides with the axis of the lower rotating shaft.

[0014] This utility model has substantial features and advancements compared to the prior art. Specifically, the burner angle adjustment mechanism provided by this utility model uses a burner mounting plate that can be oscillated on the outside of the combustion furnace shell. The combustion furnace burner is directly mounted on the burner mounting plate, and the combustion furnace burner is oscillated to change the inclination angle of the inner end of the combustion furnace burner in the inner assembly hole. Thus, the combustion furnace burner angle can be changed simply by changing the oscillating position of the burner mounting plate without altering the burner structure, making it convenient to adjust the combustion furnace burner angle.

[0015] This invention analyzes the structure of existing combustion furnace burners and, while ensuring the integrity of the existing combustion furnace burner structure, adds a burner mounting plate that can swing up and down on the outside of the combustion furnace shell. By swinging the burner mounting plate, the angle of the combustion furnace burner can be changed.

[0016] Furthermore, a guide groove plate is provided on the upper part of the outer side of the combustion furnace shell, and a rotating sleeve is provided on the lower part of the outer side of the combustion furnace shell. The upper part of the burner mounting plate is adjustablely connected to the guide groove plate by the upper rotating shaft, and the lower part of the burner mounting plate is rotatably connected to the combustion furnace shell by the lower rotating shaft; thus ensuring the stability of the swing process.

[0017] Furthermore, by opening arc-shaped guide grooves on the guide groove plate and setting nuts at both ends of the upper rotating shaft, the swinging process of the burner mounting plate can be guided. At the same time, after adjusting the angle, the burner mounting plate can be fixed on the guide groove plate using the nuts, which increases the stability of the burner mounting plate.

[0023] The burner mounting plate 5 is swayably disposed on the outside of the combustion furnace shell 1, and is used to install the combustion furnace burner 10 and drive the combustion furnace burner 10 to sway, so as to change the inclination angle of the inner end of the combustion furnace burner 10 in the inner assembly hole 8.

Nuts are threaded to both ends of the upper rotating shaft 3, and the nuts are used to connect the upper rotating shaft 3 to the guide plate 2.

[0026] Specifically, the burner mounting plate 5 has an external mounting hole 7 for the inner end of the combustion furnace burner 10 to pass through, and the external mounting hole 7 is arranged opposite to the internal mounting hole 8. The guide groove plates 2 are respectively arranged perpendicular to the combustion furnace shell 1. The rotating sleeves 6 are respectively arranged parallel to the combustion furnace shell 1. Example 2
