Description

Technical Field

[0001] The utility model belongs to the technical field of practical tools for rotary kilns, and specifically discloses a rolling support for a tool for cleaning the hearth nodules of a rotary kiln. Background Art

[0002] The molybdenum concentrate roasting process is a typical exothermic reaction. Under industrial production scale conditions, it can completely carry out self-heating. The application of the project of "self-heating roasting method and device for molybdenum concentrate" independently developed by our company has enabled the smelting company to embark on the green smelting path of carbon-free roasting, environmental protection and energy conservation. However, because the grades of molybdenum concentrate selected by each concentrator and the proportions of flotation agents added are different, when smelting reactions occur in the rotary kiln, the materials will form a ring and block, which not only reduces the quality of the calcined products, but also increases the weight of the rotary kiln itself, indirectly causing wear of the rotary kiln bearings and seriously affecting the output of molybdenum oxide. If production is stopped for cleaning, the cost is relatively high and it affects the company's benefits. Only tools can be used to clean the hearth nodules of the rotary kiln, which is time-consuming and laborious.

[0003] Currently, the lengths of the tools for cleaning the hearth nodules of rotary kilns of different specifications are generally more than 30 meters. As shown in the appendix, Figure 1 there are many problems in using tools to clean the hearth nodules of rotary kilns: 1. When cleaning the hearth nodules of the rotary kiln, because the cleaning tool for the hearth nodules is too long, its hardness is affected. If there is no support frame in the middle part of the tool, it is easy to deviate when entering and leaving the rotary kiln and fall off the support frame, posing a safety hazard, and it is also easy to increase the difficulty of cleaning the hearth nodules of the rotary kiln due to friction with the ground; 2. Due to site restrictions, the tool for cleaning the hearth nodules of the rotary kiln needs to be cut into sections for storage and welded together again during use. Convexities are easily generated at the welded joints of the steel pipes. When the tool enters the kiln body through the steel pipe support frame, it is easy to trip over the support frame, posing a safety hazard; 3. If there is no support frame at the front end of the tool, it is not easy to control the direction of cleaning the hearth nodules, resulting in incomplete cleaning of the hearth nodules. Therefore, a special support frame is needed to support the tool for cleaning the hearth nodules of the rotary kiln. Summary of the Invention
