[0038] During operation, in order to improve the stirring and mixing effect of the stirring device in this scheme and avoid the accumulation of raw materials affecting the stirring and mixing effect, in this scheme, in the initial state, the spring 28 will always push the cross limit plate 27 downward, and drive the sealing plug 26 to seal the hole in the middle of the annular limit plate 24 through the cross limit plate 27 and the pull rod 25 for sealing. When the pressure pump 23 transports the gas in the high-pressure gas storage tank 22 to the mixing tank 1, it will be located under the No. 2 partition 17. When the air pressure under the No. 2 partition 17 is greater than the downward thrust of the pull rod 25, the gas under the No. 2 partition 17 will push the sealing plug 26 upward, so that the sealing plug 26 moves upward to open the hole in the middle of the annular limit plate 24, and the gas will enter between the No. 1 partition 15 and the No. 2 partition 17 from the gap between the sealing plug 26 and the annular limit plate 24, so as to blow the raw materials located on the No. 1 partition 15 upward through the through hole 16 to improve the stirring and mixing efficiency.

When the driving motor 14 operates, it will drive the rotating main shaft 3 to rotate in the rotating sleeve 2, and when the rotating main shaft 3 rotates, it will drive the central stirring rod 4 located thereunder to rotate, and when the central stirring rod 4 rotates, it will drive the central support rod 5 to stir the raw materials in the mixing tank 1, and when the rotating main shaft 3 rotates, it will drive two sets of side stirring components to rotate around the rotating main shaft 3 as the axis. During operation, the rotating main shaft 3 drives the side sleeve 7 to rotate around the rotating main shaft 3 through the horizontal rotating plate 6, and when the side sleeve 7 rotates, it will drive the side stirring rod 8 to follow the rotation, and when the side stirring rod 8 rotates around the rotating main shaft 3, it will drive the gear 13 rotates around the gear ring 11, and the gear 13 is meshed with the gear ring 11. When the gear 13 rotates around, the side stirring rod 8 is driven by the gear 13 to rotate in the side sleeve 7, and when the side stirring rod 8 rotates, it drives the side support rod 9 to stir the raw materials in the mixing tank 1. At this time, the side stirring rods 8 in the side stirring assemblies on both sides will drive the side support rods 9 to rotate while revolving around the central stirring rod 4.

During the rising process of the gas, the raw materials on the No. 1 partition 15 will be brought upward, and the central support rod 5 arranged vertically is staggered between the side support rods 9 arranged vertically. When the side support rods 9 and the central support rod 5 are stirred, a large number of eddies will be generated in the gap to avoid the accumulation of raw materials when the raw materials are mixed and stirred, thereby improving the stirring and mixing efficiency. In the initial state, the spring 28 will always push the cross limit plate 27 downward, and the sealing plug 26 will be driven by the cross limit plate 27 and the pull rod 25 to seal in the annular limit The hole in the middle of the plate 24 is opened for sealing. When the pressure pump 23 delivers the gas in the high-pressure gas storage tank 22 to the mixing tank 1, it will be located under the second partition 17. When the air pressure under the second partition 17 is greater than the downward thrust of the pull rod 25, the gas under the second partition 17 will push the sealing plug 26 upward, so that the sealing plug 26 moves upward to open the hole in the middle of the annular limit plate 24, and the gas will enter between the first partition 15 and the second partition 17 from the gap between the sealing plug 26 and the annular limit plate 24, so as to blow the raw materials on the first partition 15 upward through the through hole 16, thereby improving the stirring and mixing efficiency, and achieving the effect of improving the mixing effect of the raw materials.
