Description

Technical Field

[0001] The utility model relates to the field of coal mine dust removal devices, in particular to a coal preparation and dust removal device. Background Art

[0002] A large amount of coal dust will be generated in the coal preparation process. If the coal dust is discharged directly without treatment, it will not only pollute the environment of the construction site, but also affect the health of the construction workers. At the same time, a certain concentration of coal dust will produce a violent explosion when encountering an open flame, causing a safety accident. Therefore, a dust removal device is needed. For this purpose, a coal preparation dust removal device is proposed.

[0003] Most of the existing dust removal devices separate the water used for dust reduction from the coal slag through a filter screen, so the filter screen needs to be taken out and cleaned after a long period of use, which is relatively troublesome. In addition, most of the existing dust removal devices cannot effectively recycle the water used for dust reduction, which may result in the use of a large amount of water resources when performing dust reduction treatment. Therefore, technical improvements are urgently needed.
