The plasma heating unit 41 adopts plasma electrothermal technology and includes a plasma electric flame electrode 411, a graphene electric heating plate and a carbon fiber auxiliary heating mesh 412, a circulating air duct 413, and a support 414. The plasma electric flame electrode 411 is connected to the graphene electric heating plate and carbon fiber auxiliary heating mesh 412 through the circulating air duct 413. A support 414 is provided between the graphene electric heating plate and the carbon fiber auxiliary heating mesh 412 and the circulating air duct 413.

It is an intelligent control system that achieves efficient electrical energy conversion, reduces energy consumption, and improves heating efficiency through electric flame heating and carbon fiber thermal conductivity. The fan 31 on the heat exchange power unit 3 is started to drive the airflow of the entire dryer system.

After the material in the drum tunnel 1 is dried by heat exchange, the residual hot air is discharged through the exhaust end 2 and re-enters the heat exchange power unit 3.

[0032] The drum tunnel 1 is divided into a drum shell 11 and a drum inner liner 12. The drum inner liner 12 is rotatably installed inside the drum shell 11 via a first support shaft 15 and a second support shaft 16 symmetrically arranged on both sides and a limiting shaft 14 above them.

The residual heat air in the first residual heat air transmission pipeline 31 passes through the second preheated air transmission pipeline 44, the third residual heat air transmission pipeline 47, and the residual heat air output pipeline 46 in turn, and finally enters the drum inner barrel 12 through the residual heat air output port 54 on the hollow shaft 53. The other way of residual heat air passes through the recycling air box 43 of the plasma heating part 41, and is heated by the plasma heating method of the heating box 45. The heated medium enters the hot air box 48, and finally enters the drum inner barrel 12 through the blades 52 opened on the distribution disc 51. The residual heat air is divided into two paths and enters the drum inner barrel 12. The medium input through the residual heat air output port 54 has low temperature, and the medium input through the opened blades 52 has high temperature. The high and low temperature mixing method is combined with the water content of the to-be-dried articles and other working conditions to appropriately select the opened blades 52 and the heating temperature of the heating box 45 or directly use the residual heat air for circulation blowing. Compared with the traditional heating and drying method, it is more energy-saving and has more selectivity.

The difference between the plasma heating dryer of this embodiment and the above-mentioned embodiments is that the blades 52 on the distribution disc 51 are connected with connecting rods 57, the other ends of the connecting rods 57 are connected with the telescopic ends of the air cylinders 56, and the cylinder bodies of the air cylinders 56 are selectively fixed at any position except the blades 52. When the air cylinders 56 are extended, the two connecting rods 57 connected with the air cylinders 56 are pushed to both sides, thereby driving the blades 52 to open. The medium enters the drum inner barrel 12 through the gap of the opened blades 52. When the air cylinders 56 are retracted, the two connected connecting rods 57 are close to the same side, thereby closing the blades 52 on the distribution disc 51. One air cylinder 56 can control two adjacent blades 52 to open or close at the same time.

[0036] Example 4, in combination Figures 1-4 , Figure 6 and Figure 7The difference between the plasma heating dryer of the embodiment and the embodiment 3 is that the blade 52 is connected with one end of the connecting rod 57, the other end of the connecting rod 57 is connected with the sliding block 61, the sliding block 61 is threadedly connected with the screw rod 60, one end of the screw rod 60 passes through the fixed seat 59 and is connected with the execution end of the driving motor 58, the driving motor 58 is installed at a fixed position outside the air inlet distribution part 5 through the fixed seat, the driving motor 58 is turned on to drive the screw rod 60 to rotate forward or reversely, thereby driving the sliding block 61 to move forward or backward, when the sliding block 61 moves forward, the two connecting rods 57 hinged with the sliding block 61 are opened to the two sides, thereby driving the blade 52 to open, when the sliding block 61 moves backward, the two connecting rods 57 hinged with the sliding block 61 are closed inward, thereby driving the blade 52 to close.
