Description

Technical Field

[0001] The utility model relates to the technical field of dust removal pipelines, in particular to a connecting pipeline with a dust removal function. Background Art

[0002] Dust-proof connecting ducts generally refer to duct systems used to control and reduce the spread of dust in industrial production and processing processes. These duct systems are generally designed to effectively collect, transfer and process dust in factories, workshops or other industrial sites to ensure a clean and safe working environment. They can be used in conjunction with dust collection equipment, filters and other dust control equipment to minimize the impact of dust on worker health and equipment.
