Description

Rotary kiln barrel body part

Technical Field

The utility model relates to a calcining kiln equipment field especially relates to a rotary kiln barrel body part.

Background

2-3 rolling rings and chain wheels need to be welded on the outer ring of the rotary kiln cylinder, the total length of the cylinder is 20-30 m, and the cylinder is supported on a supporting wheel through the rolling rings. In the prior art, when a rolling ring is welded on a barrel, a base plate is placed between the rolling ring and the barrel or a chain wheel and then welded, the rolling ring and the barrel are easy to deform in the welding process, the concentricity of the rolling ring and the barrel cannot be guaranteed, and the barrel and sealing covers at two ends are difficult to seal. The welded rolling rings still need to be turned to form an excircle, otherwise, the rolling rings are not in complete contact with the riding wheels, the rolling rings and the riding wheels are easy to wear, and the barrel is long and difficult to machine, a large lathe needs to be selected, a special fixture is designed, the machining cost for welding two rolling rings on the short barrel is more than sixty thousand yuan, the machining cost for welding three rolling rings on the long barrel is more than hundred thousand yuan, the machining cost is very high, and the production period is long. In the process of welding the rolling ring and the chain wheel, the rolling ring and the cylinder body are easy to deform, the concentricity of the rolling ring and the cylinder body is not ensured, and chain transmission is not stable. It is therefore desirable to provide a barrel component that ensures concentricity of the rolling rings after welding to the barrel.
