Rectification device for continuous methanol production

The utility model provides a rectification device for continuous methanol production, which relates to the technical field of methanol production and comprises a support component comprising a support frame. During use, the motor is started to enable the output shaft of the motor to rotate so as to drive one of the two-way screw rods to rotate, at the moment, under connection and conveying of the belt, the two rotating blocks rotate at the same time, so that the two two-way screw rods rotate at the same time, and the movable blocks move towards the two sides on the two-way screw rods so as to drive the two-way screw rods to rotate at the same time. When the rectifying device body is moved, the connecting rod rotates from an approximately horizontal state to a state perpendicular to the fixed rod, at the moment, the bottom end of the connecting rod pushes the sliding block downwards, so that the universal wheel is driven to move downwards until the connecting rod is completely perpendicular to the fixed rod an
