Technical Field

[0001] The utility model relates to the technical field of pipeline rust removal, in particular to a dust purification device for rust removal of electromechanical pipelines. Background Art

[0002] Electromechanical pipelines refer to pipeline systems used to transport fluids, gases, solids and other media, mainly including two categories: mechanical equipment pipelines and electrical equipment pipelines.

[0003] During the construction of hydrogen energy plants, a large number of electromechanical pipelines need to be laid. Some pipelines will have rust spots on their surfaces due to improper storage, which requires rust removal. Currently, common pipeline rust removal machines mostly adopt a semi-closed structure (feed ports and discharge ports for pipeline entry and exit are set on the casing), and multiple motor-driven grinding heads are set inside. Although such equipment can quickly remove rust from pipelines and collect most of the rust and dust, some dust will still escape from the inlet and outlet of the pipeline, causing pollution to the working environment.
