The inner core shaft and the outer core shaft are respectively supported by bearing No. 1 and bearing No. 2, and bearing No. 1 and bearing No. 2 play a supporting and axial fixing role on the inner core shaft and the outer core shaft, thereby ensuring the axial positioning and independent rotation between the inner core shaft and the outer core shaft; The inner core shaft is a hollow shaft, comprising a batching inlet, a batching channel, and a batching nozzle, wherein the batching channel is arranged in the middle cavity of the inner core shaft away from the driving main body shell, the batching nozzle is arranged at the end of the inner core shaft away from the driving main body shell, the end of the inner core shaft close to the driving main body shell is in a sealed state, the batching nozzle is arranged in the middle position of the conveying blade and the stirring blade, and the batching channel is communicated with the batching inlet and the batching nozzle; The stirring blade and the conveying blade should be spaced a certain distance apart, the length of which is 0.1-0.5 times the height of the stirring body shell; When the stirring blades are arranged on multiple axes, the staggered angle of each group of stirring blades between two axes is 90 degrees to avoid mutual interference during the rotary stirring process; The conveying blade is an integral spiral blade, which is connected to the outer core shaft by welding; the stirring blade is a sheet structure, two pieces form a group, the angle between the two sheet structures is 180 degrees, each group of stirring blades is connected to the inner core shaft by screws, and the number of stirring blade groups is set in the range of 2-100 groups, and the number of stirring blade groups can be adjusted according to the stirring design plan; The number of the stirring modules can be set to 2-10, the distance between the core shafts of the sleeves of each adjacent stirring module is 1.0-2.0 times the length of the stirring blades, the staggered angle of each group of stirring blades between each adjacent stirring module is 30-90 degrees, and the arrangement of each group of conveying blades between each adjacent stirring module should be staggered by 1-100 cm to avoid mutual interference in the rotary stirring process; The driving module includes a large chain, a small chain, a large sprocket, a small sprocket, a large chain pressure wheel, a small chain pressure wheel, and a coaxial dual motor; the large sprocket is connected to the outer core shaft by a key connection, and the small sprocket is connected to the inner core shaft by a key connection; the large chain and the small chain transmit the power of the two motors to the large sprocket and the small sprocket respectively, and then the large sprocket drives the outer core shaft to rotate, and the small sprocket drives the inner core shaft to rotate; the coaxial dual motor is a coaxial symmetrical arrangement of two motors, The speed can be controlled by the frequency regulator respectively; the large chain pressure wheel and the small chain pressure wheel are welded through the outer shell module of the cylindrical metal rod, and the outer edges of the large chain pressure wheel and the small chain pressure wheel are provided with circular grooves, and they can rotate freely with the circular metal rod as the axis. The large chain pressure wheel overlaps the large chain through its circular groove, and the small chain pressure wheel overlaps the small chain through its circular groove. The large chain pressure wheel and the small chain pressure wheel can respectively press the large chain and the small chain to prevent tooth skipping; The outer diameter of the conveying blade should be less than or equal to the length of the stirring blade, and the length of the stirring blade ranges from 10 to 50 cm; The speed of the conveying blade and the stirring blade can be adjusted separately, and the stirring blade speed must be greater than the conveying blade speed; Material A enters the conveying blade section through the feed inlet, and the conveying blade conveys material A to the end of the conveying blade. Since there is a storage space between the conveying blade and the mixing blade, material A is transported to the storage space by the conveying blade and then piled up freely. After material A is full, it is squeezed by the conveying blade and moves to the mixing area. Material B is blown to the batching nozzle through the batching channel. Material B is ejected with the blowing gas to form a gas cutting state for material A, and material B and material A are preliminarily mixed during the cutting. Then the preliminary mixture is pushed to the mixing blade for further stirring. Since the accumulation of material A blocks the gas discharge channel to the discharge port, the blowing gas will move toward the discharge port, and the mixed material A and material B are gradually transported to the discharge port. A dust removal device is installed above the discharge port. The dust removal device adsorbs and purifies the excess dust and blowing gas and then discharges them.
