[0020] The upper end of each of the three second flanges 77 is attached to the upper end of each of the three first flanges 74, and each of the three first flanges 74 is sealingly connected with the three second flanges 77 through a plurality of connecting bolts 75 and a plurality of connecting nuts 76, the three second flanges 77 and the three first flanges 74 can make the three cylindrical pins 79 be inserted into the three high-temperature-resistant exhaust pipes 7, the upper end surface of each of the three cylindrical pins 79 is provided with a push-pull piece 78, each of the three fixed rubber rings 712 is inserted into the inner side of each of the three high-temperature-resistant exhaust pipes 7, the push-pull piece 78 facilitates the staff to push and pull the cylindrical pin 79, thereby facilitating the discharge of high-pressure gas inside the drum body 1, and the fixed rubber ring 712 can prevent the possibility of leakage of small raw materials inside the drum body 1.

[0021] As an embodiment of the present invention: three high-temperature resistant exhaust pipes 7 are provided with exhaust ports 713 on the upper right side of the annular side. Each of the three exhaust ports 713 is welded with an L-shaped exhaust pipe 714. Each of the three L-shaped exhaust pipes 714 is provided with a valve 715 on the annular side. The L-shaped exhaust pipes 714 and valves 715 facilitate the manual guidance and discharge of high-pressure gas inside the drum body 1 by the operator. A pressure gauge is provided in the middle of the upper end face of the drum body 1. The pressure gauge facilitates the operator to know the internal pressure of the drum body 1. Multiple lifting plates 8 are fixed inside the drum body 1 and multiple sleeves 4 through a dispersing structure 82.

[0023] As an embodiment of the present invention: after the drum body 1 has been drying for a certain period of time, the pressure gauge is observed. If it is found that the internal pressure of the drum body 1 is too high, the push-pull plate 78 is pulled upwards (e.g., Figure 1 As shown, the three high-temperature resistant exhaust pipes 7 are all located above the drum body 1. The cylindrical pin 79 will drive the circular movable plate 711 and the fixed rubber ring 712 to slide upward in the high-temperature resistant exhaust pipe 7 (during this process, the compression spring 710 will be compressed) until it is pulled up to a certain extent. Then, the valve 715 is opened, which allows the gas inside the drum body 1 to pass through the high-temperature resistant movable venting mesh 72 and the high-temperature resistant fixed venting mesh 73 and be discharged to the outside through the exhaust port 714 and the L-shaped exhaust pipe 714. After the pressure gas inside the drum body 1 is discharged, push the push-pull plate 78 downward. The cylindrical pin 79 will drive the circular movable plate 711 and the fixed rubber ring 712 to slide downward in the high-temperature resistant exhaust pipe 7 until the valve 715 is blocked. Then, the valve 715 is closed. The high-temperature resistant movable venting mesh 72 and the high-temperature resistant fixed venting mesh 73 can prevent the raw materials inside the drum body 1 from leaking into the high-temperature resistant exhaust pipe 7. The overall operation is convenient and quick.
