The invention discloses a multifunctional mixing stirring system. The system comprises an elevator, a feeding hopper, a stirring chamber, a conveying mechanism bearing materials in the stirring chamber, a solvent chamber and a mixing stirring mechanism, wherein the feeding hopper and the stirring chamber are arranged at the two ends of the elevator; the solvent chamber is connected to the mixing stirring mechanism through a pipeline, the conveying mechanism is a two-way conveying mechanism, and a first discharging port and a second discharging port are respectively formed in the two ends of the conveying structure; a feeding port is formed in the upper side surface of the conveying mechanism and connected with the stirring chamber, the first discharging port is connected to a mixing stirring device, and the second discharging port is connected with the feeding hopper. The multifunctional mixing stirring system is simple in structure, capable of achieving circulating mixing of powder materials and high in mixing degree; conveying and stirring systems and other systems only need a small motor to achieve the uniform mixing effect, and the energy-saving effect is ensured; the automation degree is high, and self-cleaning of a mixing system can be achieved; the small mixing system is small in occupied area, mixing and discharging are synchronous, and the production efficiency is improved.
