Sludge Dryer

In view of the fact that sludge is easy to agglomerate during dehydration, the material plate structure of the general single-channel dryer has been changed, and a combined self-cleaning device has been adopted, which greatly expands the application range of the single-channel dryer. It can not only dry various types of sludge, but also various high-viscosity materials.

● Can process sludge with a water content of 60%-80%, with strong adaptability
● The drying cylinder is equipped with a lifting plate to ensure that the material is heated evenly and dried fully.
● The dryer has a high degree of automation and adopts advanced fuzzy control system to achieve automatic control of product quality.
● The sludge dryer has the advantages of reasonable structure, fine workmanship, high output, low energy consumption and convenient operation.

The sludge dryer can dry materials with a moisture content of 80% into finished products at one time. In view of the fact that sludge is easy to agglomerate during drying, the material plate structure of the general single-channel dryer has been changed, and a combined self-cleaning device has been adopted, which greatly expands the application range of the single-channel dryer. It can not only dry various types of sludge, but also various high-viscosity materials.
The sludge enters the guide plate inside the dryer through the chute from the feeder. As the cylinder rotates, the sludge is guided to the inclined lifting plate and lifted to the center of the cylinder. It gradually falls to form a material curtain, and the high-temperature airflow passes through it, preheating the sludge and evaporating part of the water. When the sludge falls and moves to the movable grate-shaped wing plate, the material is mixed with the preheated grate-shaped wing plate, transferring heat to the material, causing part of the water to evaporate. At the same time, the wing plate carries the material to be lifted and scattered, and repeats this process many times, so that the material and the hot air flow undergo convection and contact heat exchange. At the same time, the cleaning device buried in the material also slides down along the inner side of the arc-shaped lifting plate to clean up the material adhering to the inner wall of the lifting plate. After the cleaning device rotates through the vertical line with the cylinder, it drags on the back of the arc-shaped lifting plate to clean up the material adhering to the outer wall of the lifting plate. As the cylinder rotates continuously, part of the water evaporates and the sludge is further dried. At the same time, the cleaning device also breaks up the sludge balls, which increases the drying speed. Finally, the sludge becomes loose material with low moisture after drying and is discharged from the discharge port.
