The invention relates to a vertical type mixing and heating device capable of mixing stirred materials. The vertical type mixing and heating device comprises a tank body, an upper cover, a
hearth, a stirring reactor, a burner, a stirring
cutting assembly and a power driving device. The upper end of the tank body is open, and the upper cover is detachably installed at the open end of the tank body. The
hearth is installed on the inner bottom wall of the tank body. The stirring reactor is fixed to the inner wall of the tank body through a support and located above the
hearth. The burner is installed outside the tank body, and a
sprayer portion of the burner sequentially penetrates through the tank wall of the tank body and the lateral wall of the hearth and extends into the hearth. The stirring
cutting assembly is arranged inside the stirring reactor. The power driving device is fixed to the upper cover and located above the stirring
cutting assembly. The driving end of the power driving device extends downwards into the stirring reactor to be connected with the stirring cutting assembly. The vertical type mixing and heating device has the advantages that the structure is simple, usage is convenient, the stirred materials are evenly heated in the stirring process, the heat
utilization rate of the burner is high, the crushing effect on the stirred materials is good, the uniformity and heating uniformity of the stirred materials are improved, and the stirring effect is excellent.
