Molten iron desulfurization equipment and quick connecting device for rotary desulfurization spray gun of molten iron desulfurization equipment

The invention discloses molten iron desulfurization equipment and a quick connecting device for a rotary desulfurization spray gun of the molten iron desulfurization equipment. The quick connecting device for the rotary desulfurization spray gun comprises a clamping base used for being fixedly connected with a rotary main shaft, and a rotary fixed connection assembly rotationally connected with the clamping base. A limiting cavity used for clamping the spray gun is formed by the rotary fixed connection assembly and the clamping base. The quick connecting device further comprises a pipeline connecting assembly. The two ends of the pipeline connecting assembly are used for being connected to an outlet of a hollow pipeline of the rotary main shaft and an inlet of a hollow pipeline of the spray gun correspondingly. The quick connecting device for the rotary desulfurization spray gun is simple in structure, safe, reliable and convenient to machine and install, under the condition of the same weight, the strength a
