[0055] Second, at this time, the motor 5 is reversed, the motor 5 will drive the spiral feeding rod 9 to rotate clockwise through the meshing of the transmission bevel sleeve 12 and the second end face bevel ring 14, at this time, the spiral feeding rod 9 will send the heavy materials falling to the bottom end of the reaction kettle 2 to the top end along the lifting cylinder 7, and then the heavy materials will be discharged along the opening at the top end of the lifting cylinder 7, and then the heavy materials will sink again under the action of gravity, forming an internal circulation mixing, during the mixing process, the spiral feeding rod 9 and the stirring cylinder 8 can be alternately operated according to the actual needs, and the two work together to ensure that the light materials can be fully mixed with the heavy materials, after the mixing is completed, the mixture needs to be reacted in the reaction kettle 2 for a period of time, during which the motor 5 is continuously reversed, and the mixture is continuously internally circulated through the spiral feeding rod 9 to avoid stratification of the mixture due to static.
