[0026] The vent cylinder 12 is installed at one end of the drying cylinder 11, and its input end is equipped with an introduction head 14, which is designed to be conical, so as to be closely connected with the output port of the air pump 15. The air pump 15 is fixed by a connection sleeve 16 to ensure air tightness. The air delivery cylinder 13 is located at the other end of the drying cylinder 11, and a delivery head 17 is provided at the output end, and the dried air is discharged or recycled through a delivery pipe 18.

[0027] The diversion partition 21 is distributed between the vent cylinder 12 and the drying cylinder 11, which plays a diversion effect and ensures that the incoming air can be evenly distributed in the entire drying cylinder; the heat source 22 uses an air source heat pump as a heat source and is installed in the middle of the inner cavity of the drying cylinder 11. It absorbs heat from the outside air and circulates it through the heat pump to efficiently provide heat energy; the heating drying bar 23 is arranged on both sides of the heat source 22 to increase the air contact area and improve the drying efficiency; the heating roller group 24 surrounds the outer periphery of the heating drying bar 23 to assist in heating the air in the drying cylinder to ensure that the drying temperature is uniform and controllable.

[0028] This embodiment can be externally connected to a related intelligent control system, and the heating drying bar 23 and the heating roller group 24 can be connected thereto to intelligently control the amount of heating, thereby automatically adjusting the drying heat according to parameters such as material type and humidity.

[0029] Embodiment 2:

[0030] The diversion partition 21 includes an air guide baffle 31 installed in the ventilating cylinder 12 and a branch baffle 32 installed on the air guide baffle 31, and a branch channel 33 is formed between the air guide baffle 31 and the branch baffle 32.

[0031] The air guide baffle 31 is installed horizontally in the ventilator 12, and branch baffles 32 are evenly distributed on its surface to form two branch channels 33. The branch channels 33 can ensure that the air entering the drying barrel 11 flows evenly and stably, thereby improving the drying efficiency. The heating core 41, as the main heat source generator, is installed at the center line of the inner cavity of the drying barrel 11. The heating coil 42 is tightly wound around the periphery of the heating core 41, and high-temperature heat energy is generated through electric heating or heat pump circulation.
