The embodiment of the invention provides a material backflow type continuous rectifying furnace, and relates to the field of rectifying towers. The material backflow type continuous rectifying furnace comprises a tower body used for rectifying treatment and a tower plate arranged in the tower body, and further comprises a rotating groove formed in the inner wall of the tower body in an inward sunken mode, meanwhile, a rotatable rotating ring is connected to the peripheral face of the tower plate in a sleeving mode, and the upper end of the rotating ring extends upwards to be provided with an overflow dam used for fencing a solution. An overflow plate which extends downwards from the lower end of the rotating ring to one side above the tower plate and is used for draining the drainage solution can enable a speed reducer connected with the driving end of the motor to drive the first rotating rod to rotate through rotation of the motor, and then the rotating ring can rotate together through magnetic driving afte
