Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, and in particular to a combined metallurgical safety pipeline. Background Technology

[0002] Metallurgy refers to the process and technology of extracting metals or metal compounds from minerals and processing them into metallic materials with certain properties using various processing methods. In the metallurgical process, metallurgical powders need to be transported. The transport methods include mechanical transport, pneumatic transport, and container transport. Among them, pneumatic transport refers to the transport method of conveying dry, loose solid particles or granular materials in pipelines by means of air flow. The air flow directly provides the energy required for the movement of material particles in the pipeline. The air flow in the pipe is driven by the pressure difference between the two ends of the pipe. Therefore, the sealing of the connection between pipelines is very important.

[0003] However, existing pipe connections often lack reinforcement structures, making them prone to deformation during use. This can lead to gas leakage, affecting the pneumatic conveying effect. Furthermore, existing metallurgical powder conveying pipes are typically fixed with support frames, making them susceptible to vibrations from surrounding vehicles. Utility Model Content
