The compression spring can stretch and deform under the action of external force, so that the elastic support assembly can be flexibly adjusted according to the change of the shape of the outer wall of the rotary kiln body, and the elastic support of the support structure on the rotary kiln body is realized.

Furthermore, a limiting groove is axially arranged on the inner wall of the barrel in parallel, and a limiting sliding block matched with the limiting groove is arranged on the bottom surface of the rod body. The limiting slide block is matched with the limiting groove, so that the rod body can only translate along the axis and cannot rotate around the axis, and uneven stress caused by the fact that the axis of the supporting wheel is not parallel to the axis of the rotary kiln body is prevented.

Furthermore, the rotary kiln further comprises a driving assembly, wherein the driving assembly comprises a driving motor, a toothed ring coaxially sleeved on the outer wall of the rotary kiln body and a transmission gear meshed with the toothed ring, and a rotating shaft of the transmission gear is connected with the driving motor. The driving assembly can drive the rotary kiln body to rotate around the axis of the rotary kiln body.

The utility model also comprises other components which can lead the calcining equipment to be normally used, and all the components are the conventional choices in the field. Additionally, the utility model discloses in not all adopt the conventional means in this field with limited device or subassembly, for example, the rotary kiln body, roll the circle, base station, riding wheel, barrel, the body of rod, compression spring, mounting bracket, driving motor, ring gear, drive gear etc. all adopt conventional setting.

Compared with the prior art, the beneficial effects of the utility model are that:

this device is through setting up elastic bearing structure, can absorb the swing of the rotation in-process that the rotary kiln body caused because of self outer wall deformation to a certain extent, makes equipment operation more steady to reduce the loss of accessory, reduce the running cost of equipment.
