The pneumatic mixer 2 is moved to a preset position through the mounting bracket 1, that is, the pneumatic mixer 2 is moved into the mixing barrel. When the gas supply component provides gas for the pneumatic mixer 2 and then starts the pneumatic mixer 2, the pneumatic mixer 2 drives the stirring rod 3 to rotate and stir the raw materials. At the same time, the pneumatic mixer 2 drives the stirring and cleaning component 5 to rotate and stir the raw materials.

The principle is the same as starting the pneumatic mixer 2 above. During the rotation of the stirring rod 3, the gas impacts the bottom surface of the mixing barrel to clean the mixing barrel, and the stirring and cleaning component 5 synchronously descends and rotates to clean the inner wall of the mixing barrel as the liquid level drops, having the advantage of good cleaning effect.

The through hole, the first guiding hole 252, the second guiding hole 31 and the shunt holes 32 are sequentially communicated; the gas supply component sends gas into the pneumatic motor 22 through the air inlet pipe 23 to impact the impeller to rotate and then drives the rotating shaft 25 to rotate. While the rotating shaft 25 rotates to drive the stirring rod 3 to rotate and stir the raw materials, it also drives the stirring and cleaning component 5 to rotate and stir the raw materials. The gas enters the air guiding component 4 through the air outlet pipe 24, enters the first guiding hole 252 through the air guiding component 4 and the through hole, and then enters the raw materials through the second guiding hole 31 and the shunt holes 32, thereby impacting and turning the raw materials, having the advantage of good stirring effect.

[0027] Please refer to Figures 1 to 4 In an embodiment of the present invention, the air guiding assembly 4 includes a first connecting pipe 41, a reversing valve 42, a sealing box 43 and a second connecting pipe 44. The sealing box 43 is fixedly connected to the pneumatic motor 22, the sealing box 43 is fixedly connected to the first connecting pipe 41, the first connecting pipe 41 is fixedly connected to the air outlet pipe 24, the first connecting pipe 41 is fixedly connected to the reversing valve 42, the reversing valve 42 is fixedly connected to the second connecting pipe 44, and the second connecting pipe 44 is communicated with the stirring and cleaning assembly 5.

[0028] In this embodiment, the reversing valve 42 is electrically connected to a controller or the reversing valve 42 is wirelessly connected to a controller. The reversing valve 42 is controlled by the controller. When it is necessary to stir the raw materials, air sequentially enters the rotating shaft 25 and the stirring rod 3 through the reversing valve 42, the first connecting pipe 41 and the sealing box 43, and then enters the raw materials through the stirring rod 3 to impact and turn over the raw materials. At the same time, the rotating shaft 25 drives the stirring and cleaning assembly 5 and the stirring rod 3 to stir the raw materials, which has the advantage of good stirring effect. When it is necessary to clean the stirring barrel, air enters the stirring and cleaning assembly 5 and the airbag 6 through the reversing valve 42 and the second connecting pipe 44, so that the stirring and cleaning assembly 5 abuts against the inner wall of the stirring barrel, the airbag 6 expands, the buoyancy becomes larger, and the airbag 6 drives the stirring and cleaning assembly 5 to float on the water surface.

During stirring, the rotating shaft 25 drives the hollow cylinder 51 to rotate through the cooperation of the guide rails 253 and the limit disk 55, and then drives the piston 52, the moving rod 53 and the driven plate 54 to rotate. The hollow cylinder 51, the moving rod 53 and the driven plate 54 cooperate with the stirring rod 3, having a good stirring effect. During cleaning, the air guiding assembly 4 introduces air into the hollow cylinder 51 and the airbag 6. When the airbag 6 expands to a preset internal air pressure, the air pushes the piston 52, and the piston 52 drives the driven plate 54 to abut against the inner wall of the stirring barrel through the moving rod 53. The airbag 6 drives the hollow cylinder 51 and other remaining structures to float on the liquid surface. The air guiding assembly 4 resets, and the principle is the same as above. The water level slowly drops, the driven plate 54 rotates to clean the inner wall of the stirring barrel, and the gas comes out from the stirring rod 3 to impact the bottom surface of the stirring barrel to clean the bottom surface of the stirring barrel, having the advantage of good cleaning effect.

[0033] Working principle:

[0034] Adjust the air guiding assembly 4, and the air supply member starts the pneumatic stirrer 2. The pneumatic stirrer 2 drives the stirring and cleaning assembly 5 and the stirring rod 3 to stir the raw materials at the same time. The gas is discharged into the raw materials through the air guiding assembly 4, the pneumatic stirrer 2 and the stirring rod 3, and the gas impacts and turns over the raw materials to cooperate with the stirring. During cleaning, adjust the air guiding assembly 4 to make the gas enter the stirring and cleaning assembly 5 and the airbag 6, so that the stirring and cleaning assembly 5 abuts against the inner wall of the stirring barrel. The airbag 6 expands and the buoyancy becomes larger. The airbag 6 drives the stirring and cleaning assembly 5 to float on the water surface.
