This application relates to a raw material mixing device for the production of bactericides and algaecides, belonging to the technical field of mixing equipment. It includes a mixing tank, a mixing shaft, mixing blades, and a reduction drive motor. A feeding assembly is installed at the top of the mixing tank, and multiple flow-dispersing components are also installed inside the tank. These components include a rotating body, gears, racks, and an electric push rod. The rotating body is rotatably mounted inside the mixing tank.
