Description

Technical Field

[0001] The utility model relates to the field of ironmaking production equipment, in particular to an adjustable supporting structure. Background Art

[0002] In industrial production, professional rotary kilns are often required for heating small particle materials. Rotary kilns are kiln-type thermal equipment suitable for calcining, roasting or drying granular and powdered materials. They are particularly widely used in the chemical industry. At the lower end of the rotary kiln, there is a structure supporting the furnace body. This structure not only bears the weight of the upper furnace body, but also assists the furnace body in completing various operations.

[0003] As for the current supporting structure, it is usually fixed. Since the rotary kiln is often large in size, it may increase the difficulty of loading and unloading operations to a certain extent, thereby reducing the work efficiency of the staff. In addition, the supporting structure is usually provided with fixed supporting wheels. After a period of use, the high-speed rotation often causes slight wear on the tooth grooves. Slight wear may cause the rotary kiln to shake when rotating at high speed, which in turn affects the stability and safety of the rotary kiln.

[0004] Therefore, the utility model provides an adjustable support structure to solve the problems raised in the above background technology. Utility Model Content
