High-stability reaction tank folding cover plate

The utility model discloses a high-stability reaction tank folding cover plate, which belongs to the technical field of reaction tank cover plates and comprises a tank body with an opening. The fixed cover plate is arranged at the opening; the movable cover plate is relatively separated from the fixed cover plate; the driving assembly is used for driving the fixed cover plate to do circular motion relative to the groove body; the power transmission assembly is connected between the fixed cover plate and the movable cover plate and used for transmitting torque output by the fixed cover plate to the movable cover plate, and the movable cover plate rotates reversely along with rotation of the fixed cover plate and slides along the edge of the opening. The folding cover plate structure is simplified, opening and closing of the cover plate are not affected by the use environment temperature or alkali crystallization, the cover plate is prevented from being clamped, and the operation stability of the cover plate is
