Description

Technical Field

[0001] This utility model relates to the technical field of rotary kiln equipment, specifically to an adjustable base for a rotary kiln burner. Background Technology

[0002] The burner base of a rotary kiln typically connects the central pipe to the burner body via a rotating connection, primarily used to supply combustion-supporting gas or denitrification media into the kiln. However, due to the relatively long design length of the central pipe, it is prone to structural deformation during operation due to various factors such as gravity, thermal stress, and the impact force of the combustion gas flow. This deformation can lead to significant axial movement and radial runout of the pipe.

[0003] The existence of such problems not only increases vibration and stress concentration during equipment operation, but may also negatively impact combustion efficiency, burner positioning accuracy, and pipeline lifespan, even leading to more serious equipment safety hazards. Furthermore, existing technologies lack effective design solutions to mitigate axial and radial runout. Most methods rely on thickening the pipe wall or adding supports to enhance structural rigidity, but these methods cannot fundamentally eliminate the dynamic problems caused by deformation and are ill-suited to complex operating conditions. Therefore, how to effectively eliminate these problems through innovative structural design has become a pressing technical challenge in this field. Utility Model Content
