The sludge dryer is a sludge drying equipment specially developed and designed for sludge, which has the characteristics of high moisture, high viscosity, high water holding capacity and low calorific value. It is built on the internal structure of the dryer. The special design not only improves the thermal efficiency, but also effectively avoids the sticking and over-drying of the sludge in the dryer.
The sludge dryer can dry materials with 90% water content to finished products at one time. Aiming at the characteristics of easy agglomeration and agglomeration during the sludge drying process, the material plate structure of the general single-channel dryer is changed, and the combined self-cleaning device is adopted, which greatly expands the application range of the single-channel dryer. Similar to sludge, it can also dry various high-viscosity materials.

The sludge enters the guide plate of the dryer from the feeder through the chute. As the cylinder rotates, the sludge is guided to the inclined lifting plate and then lifted to the center of the cylinder, and gradually falls to form a material curtain. , The high-temperature air flows through it to preheat the sludge and evaporate part of the moisture. When the sludge is spilled and moved to the movable grate wing, the material is mixed with the preheated grate wing, and heat is transferred to the material, so that part of the water evaporates. At the same time, the material entrained by the wing plate is lifted and scattered, repeated many times, and the material conducts convection and contact heat exchange with the hot air flow. At the same time, the cleaning device buried in the material also slides down the inner side of the arc-shaped lifting plate to clean the material adhering to the inner wall of the lifting plate. When the sweeping device rotates along the vertical line with the cylinder, it is dragged on the back of the arc hoisting plate to clean the materials adhered to the outer wall of the hoisting plate. With the continuous rotation of the cylinder, part of the water evaporates and the sludge is further dried. At the same time, the cleaning device also played a role in breaking up the sludge pellets, increasing the drying speed, and finally the sludge was dried into a loose material with low moisture, which was discharged from the discharge port.

Features of the new sludge dryer: 　1. High-efficiency and energy-saving sludge dryer. The sludge dryer adopts a new type of transmission device. Compared with general sludge dryers, it saves coal consumption by nearly 20% and saves costs for customers. It is to create value for our customers. 　2. Green environmental protection sludge dryer. The sludge dryer adopts multi-stage purification and dust removal equipment, which meets and exceeds the environmental protection standards required by the country, and reduces the pollution of the equipment to the environment.
