Axial flow pump impeller for chemical reactor

The invention relates to the technical field of axial flow pumps, and discloses an axial flow pump impeller for a chemical reactor. The impeller comprises a loading rod. A butt-joint groove is formedin the left side of the loading rod, a rotating shaft, one end of which penetrates through an extends to the left side of the loading rod is movably installed inside the butt-joint groove, a positioning groove is formed in the right side of the rotating shaft, a positioning nail, one end of which penetrates through and extends into the positioning groove is fixedly installed at the right side of the inner wall of the butt-joint groove, and an installing groove formed in the loading rod is formed in the top of the inner wall of the butt-joint groove. According to the axial flow pump impeller for the chemical reactor, due to a limiting rod arranged on a pull rod and a limiting screw on the loading rod, when a user uses the impeller, if the user needs to replace the impeller with a new impeller, the user rotates the
