Description

TECHNICAL FIELD

[0001] The utility model relates to the field of exhaust protection, especially a protection structure of exhaust pipeline. BACKGROUND

[0002] In the related industries such as coal mining and coal transportation, the safety and stability of the coal car, as a key transportation tool, is of great importance. However, the coal car currently faces a serious problem during operation, that is, the coal powder is easy to burn. The exhaust pipeline of the coal car generates a large amount of heat during work, which is easily conducted to the surrounding coal powder, becoming a potential heat source that causes the coal powder to burn.

[0003] The existing protective and thermal insulation measures cannot meet the actual needs. The traditional thermal insulation method is often simple in structure and cannot effectively prevent the transfer of heat. For example, some coal cars use ordinary thermal insulation materials, which gradually lose their thermal insulation performance in a long-term high-temperature environment, and cannot provide reliable thermal insulation protection for the exhaust pipeline.

[0004] Therefore, it is urgent to develop a protective and thermal insulation structure specifically for the exhaust pipeline of the coal car. This can reduce the risk of coal powder burning, ensure the safety and stability of the coal car during transportation, and reduce the safety hazards and economic losses caused by coal powder burning.
