The stirring assembly 4 comprises a mounting plate 5 and a rotating motor 6. The rotating motor 6 is installed on the top surface of the mounting plate 5. The top surface of the mounting plate 5 is detachably connected with the fixed end of the rotating motor 6 through bolts, so as to provide support and fixing effect for the rotating motor 6. The bottom of the mounting plate 5 is provided with two electric push rods 7. The moving ends of the two electric push rods 7 are welded with the bottom surface of the mounting plate 5. The fixed ends of the two electric push rods 7 are detachably connected with the reaction tank 1 through bolts;

[0031] The two electric push rods 7 are provided with power, so that the moving end of the electric push rod 7 drives the mounting plate 5 to move vertically. The output shaft of the rotating motor 6 is connected with the rotating rod 8 through a shaft coupling, so that the output shaft of the rotating motor 6 drives the rotating rod 8 to rotate during rotation. The rotating rod 8 is sleeved with a sealing ring 9 on the side surface, so that the rotating rod 8 rotates relative to the inner ring of the sealing ring 9, and the rotating rod 8 is sealed at the connection with the sealing ring 9.
