The sludge dryer is mainly used for drying sludge. It consists of a cylinder, a transmission device, a feeding and discharging device, a hot air system, etc. During operation, the sludge enters the cylinder through the feeding device, fully contacts with the hot air in the cylinder, and realizes water evaporation through heat exchange. It has the characteristics of high efficiency, energy saving, and environmental protection, and can quickly reduce the moisture content of the sludge and increase its value.
What are the characteristics of the internal structure of the sludge dryer?
1. Drum structure. The sludge dryer adopts a rotatable drum structure, which helps the sludge to be evenly distributed and turned during the drying process.
2. Dispersing device. A special dispersing device is provided inside, which can effectively disperse the lumpy sludge and increase its contact area with the hot air.
3. Lifting plate. A lifting plate is also installed inside the drum. When the drum rotates, the lifting plate can lift and drop the sludge, further increasing the contact opportunity between the sludge and the hot air and improving the drying efficiency.
4. Prevent adhesion. The design takes into account the fact that coal slime is easy to stick together, so the internal structure is designed to avoid sticking between materials as much as possible and reduce equipment corrosion caused by materials remaining in the cylinder.
5. Hot air path design. The internal structure also takes into account the design of the hot air flow path to ensure that the hot air can evenly pass through the coal slime layer and improve the drying effect.
