Sludge dryer product introduction

In view of the characteristics of the easy bonding block in the process of sludge dehydration, the material plate structure of the general single channel dryer is changed, and the combined self-cleaning device is adopted to greatly expand the application range of the single channel dryer, which can not only dry all kinds of sludge, but also dry various high-viscosity materials.

Outstanding advantage

1, can handle 90% water content of sludge, strong adaptability;

2, the drying cylinder is provided with a lifting plate, which can make the material heat evenly and dry fully;

3, the dryer has a high degree of automation, and adopts advanced fuzzy control system to achieve automatic control of product quality.

Working principle

The sludge enters the material guide plate of the sludge dryer through the chute from the feeder. With the rotation of the cylinder, the sludge is guided to the inclined lifting plate, that is, it is lifted to the central position of the cylinder, and gradually sprinkles to form the material curtain. The high temperature air passes through it to preheat the sludge and evaporate part of the water. When the sludge is spilled and moved to the moving grate blade, the material is mixed with the preheated grate blade, and the heat is transferred to the material, so that part of the water evaporates. At the same time, the material of the wing plate clamp belt is lifted and dropped, repeated many times, and the material and the hot air flow are convection and contact heat exchange. At the same time, the cleaning device buried in the material also slides along the inner side of the circular arc lifting plate to clean the material adhering to the inner wall of the lifting plate. When the cleaning device turns the vertical line with the cylinder, it is dragged on the back of the arc lifting plate to clean the material adhering to the outer wall of the lifting plate. With the continuous rotation of the cylinder of the sludge dryer, part of the water evaporates and the sludge is further dried. At the same time, the cleaning device also plays a role in breaking the sludge pellets, improving the drying speed, and the sludge becomes a loose material with low moisture after drying, which is discharged by the discharge port of the sludge dryer.
