[0035] Working principle: the staff first opens the steam stop valve 3 so that the high-temperature steam in the external steam generator can enter the steam guide chamber 10 to heat the drying tank 2, and then puts an appropriate amount of activated clay to be dried into the drying tank 2 through the feeding hopper 9. In this process, the height of the activated clay inside the drying tank 2 cannot exceed the height of the rotating rod 52. At this time, the heated drying tank 2 will heat and dry the internal activated clay, and then start the driving motor 51, so that the driving motor 51 drives the follower rod 53 to rotate through the rotating rod 52, and the follower rod 53 will drive the follower support rod 54 to rotate, so that the rotating follower rod 53 and the follower support rod 54 can disperse the activated clay inside the drying tank 2, so that the activated clay can be dried faster, thereby improving the drying efficiency of the drying tank 2; at the same time, the rotating rod 52 will drive the active pulley 49 to rotate, so that the active pulley 49 drives the driven pulley 48 to rotate through the transmission belt 481, and the driven drive will be driven through the transmission The rod 47 drives the supply fan blades 45 to rotate. At this time, the rotating supply fan blades 45 will blow air to the right to generate negative pressure on the left side of the processing box 46, so as to suck the exhaust gas and moisture inside the drying tank 2 through the through cavity 462 and the air outlet cavity 21. The exhaust gas sucked into the processing box 46 will first be filtered by the dust filter screen 44, and then the first purification screen 43 will purify the passing exhaust gas once, and then the second purification screen 42 will purify the passing exhaust gas for the second time. Finally, the air filter screen 41 will filter the passing exhaust gas for the second time, so as to avoid most of the volatile organic compounds and dust in the exhaust gas being directly discharged to the outside to pollute the surrounding environment, and the moisture will also be discharged to the outside together, so as to further improve the drying efficiency of the drying tank 2. At the same time, a part of the external air will be sucked into the drying tank 2 through the feeding hopper 9, so as to make the air inside the drying tank 2 circulate, and avoid the accumulation of moisture generated during the drying inside the drying tank 2.
