[0028] The working principle of the utility model:

[0029] Refer to the description attached Figures 1-5This utility model, by setting up a base 1, a top frame 2, a buffer assembly 3, a sliding bearing assembly 4, a spring 301, a piston rod 302, and a sliding bearing 402, allows the central pipe of the rotary kiln burner to pass through the sliding bearing assembly 4 between the base 1 and the top frame 2, thus fixing the base 1 and the top frame 2 in place. The sliding bearing 402 in the sliding bearing assembly 4 provides rotational support for the central pipe, and the support frame 401 provides overhead support for the sliding bearing 402. The buffer assembly 3 buffers the sliding bearing 402 through the support frame 401, thereby achieving radial buffer support for the central pipe. When the central pipe experiences radial runout and axial movement due to vibration and impact, the radial runout and axial movement of the central pipe are transmitted... The sliding bearing 402, due to its structural characteristics, allows for a relatively large axial movement, effectively accommodating the axial movement of the central pipeline and thus effectively reducing the loss caused by the axial movement of the central pipeline. At the same time, the piston rod 302 of the hydraulic cylinder provides hydraulic support to the support frame 401 under hydraulic action, thereby providing hydraulic buffer support to the central pipeline on the sliding bearing 402, which can effectively absorb and eliminate the radial runout of the central pipeline. Meanwhile, the spring 301 on the piston rod 302 provides elastic buffer support to the support frame 401 between the base 1 and the top frame 2. The elastic deformation of the spring 301 is used for buffering, which can further absorb and eliminate the radial runout generated by the central pipeline during operation.

[0030] Buffer component 3: Buffer component 3 is introduced into the burner base structure. It uses the hydraulic buffer of piston rod 302 in hydraulic cylinder and the elastic deformation of spring 301 to absorb and eliminate the radial runout generated by the central pipeline during operation, so as to ensure the stability of the equipment under vibration or impact.

[0031] Sliding bearing assembly 4 design: A sliding bearing 402 is installed at the connection between the burner base and the central pipe. For the sliding bearing 402, the axial movement is between 0.5mm and 4mm; while for the rolling bearing, the axial movement is usually no more than 0.05mm to 0.5mm. In this utility model, the sliding bearing 402 is used to provide rotational support for the central pipe, ensuring that the bearing has sufficient flexibility during operation to adapt to the small deformation and thermal expansion of the central pipe, so that the central pipe can freely adapt to axial movement, thereby effectively avoiding stress concentration or structural damage caused by restricted axial displacement.

[0032] This invention significantly improves operational stability: through the combined design of piston rod 302, spring 301 and sliding bearing 402, it effectively alleviates the radial runout and axial movement of the central pipeline caused by vibration and impact during operation, and significantly improves the operational stability of the burner.

[0033] The utility model discloses simple and reliable structure design: simple and reliable structure design, and manufacturing and installation are convenient, can be widely adapted to different working condition, have higher engineering practicality and reliability, can effectively solve the problem of small installation space.

[0034] The utility model discloses safety is remarkable promotion: through effectively reducing stress concentration, reduce equipment fatigue damage risk, the safety and operating life of rotary kiln combustion system have been greatly improved, provide the guarantee for the long -term efficient operation of combustor.

[0035] Finally, it should be pointed out that: the above-mentioned is only the preferred embodiment of the utility model, and is not used for limiting the utility model, although the utility model is described in detail with reference to the foregoing embodiment, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features.
