[0002] Concrete mixing plants mainly use sealed silos to store powdered materials such as cement, fly ash, and mineral powder. In order to effectively discharge the air pressure generated when the powder transport truck pumps the powder into the silo, a dust removal device is generally installed on the top of the silo. However, due to the limited space at the top of the silo, the dust removal device is generally limited to a small area, and the dust removal effect is limited.

The utility model is installed below the powder tank of the concrete mixing station. The dust suction assembly and the dust extraction assembly of the utility model are used to extract the dust overflowing from the dust tank and store it in the collection box, solving the problem that the dust generated by the powder tank during the unloading process is scattered in the air, causing air pollution. The utility model is simple to manufacture and easy to use, and can not only solve the problem of powder transportation, but also solve the problem of dust pollution in the air caused by the powder tank.
