Description

Technical Field

[0001] The utility model relates to the technical field of dust treatment, in particular to dust treatment equipment for coal conveying equipment. Background Art

[0002] Coal handling equipment usually includes various mechanical equipment and facilities used for coal transportation, processing and storage. Common coal handling equipment such as conveyors and crushers will generate a lot of dust at the outlet. Therefore, when using coal handling equipment, using dust treatment equipment can reduce the impact of dust on the environment and workers' health during coal transportation. Dust treatment equipment can effectively collect and remove dust particles generated during the transportation process, thereby reducing dust emissions.

[0003] When the dust handling equipment currently on the market is in use, generally the ash discharge valve on the ash hopper is directly opened to discharge the dust in the ash hopper. When the existing dust handling equipment is unloading ash, the dust falls downward and easily drifts around, resulting in the dust not being accurately collected during collection. Therefore, it is necessary to improve the current dust handling equipment of coal conveying equipment. Utility Model Content
