When the sludge is dewatered by the hot air drying system, the water content of the fed material is greatly different due to different dewatering degrees of pretreatment of the material, and the water content range is generally 60-83%. The traditional sludge drier is provided with an upper layer material conveying mesh belt and a lower layer material conveying mesh belt, wherein each mesh belt is about 30 meters long and is horizontally arranged. Under the drive of a rotating motor, the mesh belt runs in the horizontal direction to convey materials, and the drying time of the materials from a feeding point to a discharging point on the mesh belt needs more than one hour. The sludge drying process is a process that the moisture content is continuously evaporated and reduced, and the weight of the sludge on the mesh belt is continuously reduced. The horizontal installation mode's guipure presents the heavy unbalance state of anterior segment, the light unbalance state of back end because of anterior segment material moisture content is high, back end material moisture content is low. Under the state of uneven stress, the friction force between the roller at the front section and the mesh belt in the drying process is larger, the friction force between the roller at the rear section and the mesh belt is smaller, the problems that the stress of the supporting wheels is unbalanced, the power matching difference of each rotating motor is large and the like exist.
