Embodiment 1
[0028] Embodiment 1: With reference to the schematic diagrams of 2, 3, 4, and 7, the rotary jet inflatable stirring device is as shown in the accompanying drawings, including a feed pipe 1, a spiral body 2-1, a conical nozzle 3, an initial mixing pipe 4, and a throat pipe 5, It is installed coaxially in sequence, and the connection method is bolted connection. The spiral body 2-1 is a cylindrical entity with a rectangular thread groove, and a straight-through circular opening is opened in the axial direction. The rectangular thread groove is built and fixed in the straight pipe, and its major diameter is equal to the diameter D of the feeding pipe. 0 , the path is d 0 , the axial free path is D 1 , the diameter of the conical nozzle is D 2 , and d 0 >D 1 >D 2 , its pitch P is 0.25D 0 ~0.5D 0 , The helix angle is 10-30°, and the number of turns is 0.5-1.5 turns.
