Description

Technical Field

[0001] The utility model relates to the technical field of burners, in particular to a pure oxygen burner. Background Art

[0002] Pure oxygen burner is a combustion device that uses pure oxygen as an oxidant. Unlike conventional burners that use air as an oxidant, pure oxygen burners use pure oxygen to provide higher combustion temperatures and faster combustion speeds, thereby achieving a more efficient combustion process. Pure oxygen burners are generally used in industrial fields that require high temperature and high efficiency, such as metallurgy, glass manufacturing, and chemicals. In these fields, pure oxygen burners can provide higher combustion temperatures and purer combustion products, which helps to improve production efficiency and product quality.

[0003] However, most of the pure oxygen burners on the market cannot adjust the angle, which makes them inconvenient to use in certain specific application scenarios, such as in some applications where the combustion direction needs to be adjusted, and in some applications where temperature uniformity needs to be maintained (by adjusting the angle of the burner, uniform heat distribution can be achieved). Utility Model Content

[0004] The present application provides a pure oxygen burner, which can solve the problem that the existing pure oxygen burner cannot adjust the angle.

[0005] In the present application, a pure oxygen burner is provided, comprising a pure oxygen burner body, the pure oxygen burner body comprising a frame and a burner shell, a connecting shaft is fixedly provided on the burner shell, the central axis of the connecting shaft is along the horizontal direction, a mounting plate is fixedly provided on the frame, the connecting shaft is rotatably connected to the mounting plate, the rotating shaft coincides with the central axis, a first gear is fixedly connected to the connecting shaft, the central axis of the first gear coincides with the connecting shaft, a driving motor is arranged on the frame, a second gear is fixedly provided on the output shaft of the driving motor, and the first gear is meshed with the second gear.

[0006] By adopting the above technical solution, the drive motor can drive the burner casing to rotate the shaft along the horizontal direction to adjust its angle, which is more flexible and convenient; the transmission is carried out through the connecting shaft, the first gear and the second gear, the transmission effect is good and the structure is reasonable, and the drive motor can be set at a place far away from the burner casing to avoid affecting the use of the drive motor due to high temperature as much as possible.

[0007] In one embodiment, a central axis of the connecting shaft intersects with a central axis of the burner casing.

[0008] By adopting the above technical solution, the structure is more stable and reasonable.

[0009] In one embodiment, a circle of scales is arranged around the connecting shaft on the mounting plate, and an indicator block is fixedly arranged on the connecting shaft extending outward in a radial direction thereof, and the indicator block is located in front of the scales.

[0010] By adopting the above technical solution, when the burner housing is rotated, the rotation angle can be judged by the position of the indicator block on the scale.

[0011] In one embodiment, a bearing is provided between the connecting shaft and the mounting plate.

[0012] By adopting the above technical solution, the bearing can reduce the friction coefficient of the rotation of the connecting shaft and ensure the rotation accuracy.

[0013] In one embodiment, the bearing is an angular contact ball bearing.

[0014] The above technical solution is more suitable for this working environment because the angular contact bearing can bear axial force and radial force at the same time.

[0015] In summary, in the present application, a pure oxygen burner, compared with the prior art, has the beneficial effect of being able to adjust the angle of the pure oxygen burner, and can be more flexibly applied to some applications that require adjustment of the combustion direction and some applications that require maintaining temperature uniformity.
