The sludge drum dryer produced by Zhengzhou Jiutian can dry materials with high water content to finished products at one time. In view of the characteristics of easy agglomeration and agglomeration in the sludge drying process, the material plate structure of the general single-channel dryer is changed, and a combined self-cleaning device is adopted to 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.

  The drum sludge dryer is mainly composed of a double-shaft dispersing feeder, a feeding belt conveyor, a heat source system, a feeding device, and the main body of the sludge dryer (running belt, ring gear, tug, motor, reducer, heat preservation Layer, unloading device, unloading belt conveyor, cyclone dust removal or pulse dust removal equipment, waste gas treatment tower and other parts, among which the sludge drying host is the main equipment in the drying stage. In addition to the lifting plate, there are also chains and blower scattering is responsible for beating and dispersing the sludge sticking to the wall of the dryer to ensure the normal and continuous operation of the entire drying production line.

  Working principle: The sludge enters the material guide plate of the dryer from the feeder through the chute. With the rotation of the cylinder, the sludge is guided to the inclined lifting plate and then lifted to the center of the cylinder, and gradually sprinkled A material curtain is formed, through which the high-temperature airflow passes, preheating the sludge and evaporating part of the water. When the sludge is spilled and moved to the movable rafter wing, the material is mixed with the preheated rafter wing, which transfers heat to the material and evaporates part of the water. At the same time, the material carried by the wing plate is lifted, dropped, and repeated several times. The material and the hot air flow conduct convection and contact heat exchange. 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 adhered to the inner wall of the lifting plate. After the cleaning device rotates along the vertical line with the cylinder, it is dragged on the back of the arc lifting plate to clean the material adhered to the outer wall of the lifting plate. With the continuous rotation of the cylinder, part of the water is evaporated, and the sludge is further dried. At the same time, the cleaning device also breaks up the sludge pellets, which increases the drying speed. After the sludge is dried, it becomes a low-moisture loose material and is discharged from the discharge port.
