Dust removal device for concrete production

The utility model discloses a dust removal device for concrete production, which belongs to the field of building materials and comprises a packing piece arranged above a mixing device, a water inlet and a plurality of feed ports are arranged on the side edge of the packing piece, the water inlet is connected with a branch pipe penetrating through the packing piece, a plurality of water outlets are arranged on the branch pipe, and the feed ports are communicated with the water outlets. Water sprayed out of the water outlet forms a separation face to divide the interior of the packing piece into an upper part and a lower part. By arranging a branch pipe, mixed water is sprayed out in a mist form, the position where dust is generated can be located below a separation face, dust flying in the conveying and mixing process can be reduced, the dust falling effect is achieved, dust overflowing to the outside is reduced, dust in a packing piece is adsorbed and collected, the dust is separated from airflow through a d
