[0002] The dryer is a system that returns water vapor to the material during co-directional movement as the system temperature drops. During the drying process, the hot air flow moves from the tail to the front, fully contacts the material, and fully utilizes the heat transfer through heat conduction, convection, and radiation. The heat energy is directly transferred to the material, so that the moisture of the material is continuously evaporated in the cylinder. The induced draft device at the inlet draws out a large amount of moisture and wet air flow to prevent secondary pollution caused by dust discharge.

[0003] A dryer disclosed in the Chinese utility model patent application publication specification CN218936921U includes a dryer body and a conveyor belt, the conveyor belt is arranged inside the dryer body, protective mechanisms are arranged on both sides of the dryer body, and a flattening mechanism is arranged inside the dryer body, the protective mechanism includes connecting rods welded on the front and rear sides of the dryer body, and the outer surface of the connecting rod is rotatably connected with a baffle, a support plate is welded on one side of the dryer body, a fan is arranged on the top of the support plate, and a connecting pipe rack is arranged at the air inlet of the fan, and the connecting pipe rack is welded on one side of the dryer body close to the support plate, and two groups of baffles are welded inside the dryer body, and the baffles are located on the back side of the baffle.
