Sodium hypochlorite reaction tower

The utility model relates to the technical field of sodium hypochlorite production, and discloses a sodium hypochlorite reaction tower which comprises a reaction tower body, a feeding opening is formed in the outer surface of the reaction tower body, a sliding way is formed in the outer surface of the reaction tower body, a sliding block is connected to the inner wall of the sliding way in a sliding mode, and a sliding opening pipe is fixedly connected to the top of the sliding block. The outer surface of the sliding opening pipe is rotationally connected with a supporting frame, and the top of the supporting frame is fixedly connected with a telescopic rod. The feeding device has the advantages that a worker connects a material pipe with the sliding opening pipe, the sliding opening pipe on the telescopic rod is driven by the driving air cylinder to move up and down, so that the sliding block slides on the sliding way, and when the sliding opening pipe moves upwards to the position of the feeding opening, th
