Visual microbial reaction tank device capable of intelligently controlling and recording experimental data

The invention discloses a visible microbial reaction tank device capable of intelligently controlling and recording experimental data, and relates to the field of microbial reaction devices. Two ends of a cylindrical inner barrel wall and two ends of a cylindrical outer barrel wall which are coaxially sleeved are sealed and buckled by an upper cover plate and a bottom plate to form a double-layer cavity cylindrical barrel body which is provided with an inner cavity and a clamping cavity and is fastened through matching of a locking screw rod and a nut, a stirrer is arranged along the inner cavity, and a heater is inserted in the clamping cavity. A gas outlet electromagnetic valve, a methane concentration sensor, a PH value electronic sensor, a reaction material liquid level electronic distance measuring instrument, a heating liquid temperature sensor and a heating liquid level electronic distance measuring instrument are mounted on the upper cover plate; a reactant feed port electromagnetic valve, a reactant
