Uniform mixing device for high-content carbon master batch

The utility model relates to a uniform mixing device for high-content carbon master batches. The problems that in the prior art, a mixing machine is difficult to achieve reciprocating type high-frequency stirring, and stirring is not uniform enough are solved. The device comprises a horizontally-arranged mixing tank body, a plurality of feeding ports are formed in the upper side of the mixing tank body, a rotary discharging port is formed in the lower side of the mixing tank body, the two ends of the mixing tank body are rotationally positioned through a bearing support, and an outer stirring mechanism with the axis extending into an inner cavity of the mixing tank body is arranged at one end of the mixing tank body; an inner stirring mechanism axially extending to the circumferential inner side of the outer stirring mechanism is arranged at the other end of the mixing tank body, and a rotation driving assembly capable of driving the mixing tank body to rotate in the circumferential direction is arranged at o
