Device for preventing blockage and overpressure of phosphorus passing pipe of phosphorus steaming rotating pan

The invention discloses a device for preventing blockage and overpressure of a phosphorus passing pipe of a phosphorus evaporation rotating pan, and belongs to the technical field of safety of chemical production equipment. The device comprises a phosphorus steaming rotary pot and a spiral body, a phosphorus passing pipe is arranged at an outlet in one side of the phosphorus steaming rotary pot and is divided into two sections, the two sections of pipes are connected through a sealing connector, the phosphorus passing pipe close to one end of the phosphorus steaming rotary pot rotates along with the phosphorus steaming rotary pot, and the phosphorus passing pipe away from one end of the phosphorus steaming rotary pot does not rotate along with a boiler. A spiral body is arranged in the phosphorus passing pipe, the spiral body is connected with the phosphorus passing pipe close to one end of the phosphorus steaming rotary pan through a transmission mechanism, and the spiral body is driven to rotate through rot
