The gas supply assembly is partially arranged in the drum assembly, which can ensure that the high-pressure gas directly contacts the product after being blown out, improving the dust removal efficiency. The handling assembly is connected to the drum assembly and is used to drive the drum assembly to move and switch between the dust removal and product collection stations. After the drum assembly completes dust removal, it can directly move to the product collection station for one-time discharging, avoiding manual discharging one by one, improving the automation degree of the dust removal device, and effectively avoiding secondary contamination of the product by debris. The rotary drive assembly drives the drum assembly to rotate through friction transmission. The drum assembly is detachably connected to the support assembly, so that after the drum assembly completes dust removal, it can be separated from the rotary drive assembly and the support assembly at the same time, and can be freely switched between the dust removal station and the product collection station under the drive of the handling assembly.
