The utility model discloses a waterproof
powder mixing device for waterproof paint production, which comprises a
mixing tank and further comprises a mixing
assembly arranged in the
mixing tank and used for mixing waterproof
powder, the mixing
assembly comprises a rotating rod rotationally connected to the
mixing tank, and a plurality of groups of stirring pieces are arranged on the side wall of the rotating rod. Each group of stirring pieces comprises a plurality of stirring plates fixedly connected to the side wall of the rotating rod, the stirring plates are arranged in an
annular array, the inner wall of the mixing tank is rotatably connected with a rotating ring, and the inner wall of one side, close to the rotating rod, of each rotating ring is fixedly connected with a plurality of mixing plates. According to the waterproof
powder mixing device for waterproof
coating production, due to the arrangement of the mixing
assembly, an air film formed by waterproof powder and air due to large specific surface area and
high surface energy in the mixing process is subjected to shear damage, so that the direct contact opportunity of waterproof powder particles and other raw materials is improved.
