The present invention has the following advantages.

Two (mixing) shafts 4 that are equipped with in the agitator 2 pass through the drive of double gear motor case 6, because be equipped with two intermeshing's pneumatic gear in the double gear motor case 6, so two (mixing) shafts 4's rotation opposite direction to can form two strands of vortexes, two strands of vortexes enable the material intensive mixing.

The rotation speed detector 36 can monitor the rotation speed of the stirring shaft 4 so as to monitor the stirring intensity, and the monitoring value of the rotation speed detector 36 can be used for guiding the production to avoid accidents.

The double-gear motor box 6 utilizes high-pressure air as power, air enters from the air inlet 7 of the double-gear motor box 6 and is discharged from the air outlet 8, the discharged air enters the pneumatic pipeline 13 through the connecting pipe and the exhaust pipeline 10 and is discharged from the air hole 14 on the pneumatic pipeline 13, the discharged air enters the stirring barrel 2, pneumatic stirring is added on the basis of original rotary stirring, and therefore stirring efficiency is improved.

The air flow of the two pneumatic pipelines 13 enters and is controlled by the three electric control valves 12, the two pneumatic pipelines 13 can simultaneously intake air, can also respectively intake air and can also intake air at intervals by utilizing the three electric control valves 12, and regular rotational flow can be generated by the alternate intake of air due to different arrangement modes of the two pneumatic pipelines 13, and the stirring efficiency is further improved by matching with stable rotary stirring.

Because the aperture 14 on one of two pneumatic pipeline 13 increases in proper order from the past to back aperture, and the aperture 14 on the other diminishes in proper order from the past to back aperture, can use according to the condition selectivity of material when using, mainly use the pneumatic pipeline 13 that the aperture diminishes in proper order from the past to back aperture of air vent 14 when floating material is too much in the material, mainly use another pneumatic pipeline 13 when deposiing material is too much in the material. By installing the threaded plugs on the air outlet holes 14, the distribution intervals of the air holes 14 can be artificially increased, so that air can be pertinently released in a certain area in the stirring barrel 2.

The gas adding valves 19 arranged on the gas inlet connecting pipe 9 and the exhaust pipeline 10 can add special gas into the stirred materials for catalytic stirring or participating in stirring according to requirements, and when the added gas is stable, the gas can be added on the gas adding valve 19 of the gas inlet connecting pipe 9 or the gas adding valve 19 of the exhaust pipeline 10.
