I. Manganese-nickel-cobalt disc dryer--Overview of equipment

The manganese-nickel-cobalt disc dryer is a multi-layer fixed hollow heating circular loading tray, which is developed on the basis of intermittently stirring and conducting the dryer, and has been comprehensively improved. Continuous continuous heat conduction equipment. The drying process is to pass the heat carrier into the hollow disks of each layer, indirectly heat the wet material placed on the surface of the disk, and under the action of the scraping of the rotating blade, the material is continuously moved and rolled. The moisture is vaporized at the operating temperature and its vapor is withdrawn from the equipment exhaust to continuously obtain a qualified dry product at the bottom of the equipment.

The manganese-nickel-cobalt material enters the interior of the disc dryer from the feeding tube and falls on the drying tray; the motor rotates through the vertical axis to drive the arm and the blade to rotate; the material gradually moves from the center of the drying plate to the center of the drying plate by the rotation of the blade At the outer circle, and falling from the outer circle of the drying tray; through the guide plate, the material enters the center of the next drying tray; the material is repeatedly repeated in the process until it falls into the tray and is discharged through the discharge tube; the heating medium is heated The tube heats the drying tray and raises the overall temperature inside the dryer; the dryer is sealed as a whole, the temperature rises, and the pressure increases. When the pressure value exceeds the set value, a small amount of air is discharged through the vent hole; After the water content is evaporated, it is concentrated in the sump and discharged through the draft tube and the drain pipe.

By adding a guide plate, the disc dryer avoids the appearance of one large and one small drying disc inside the conventional disc dryer, and effectively increases the heating area of the heating disc under the same conditions; at the same time, the guide plate can play the role of condensing steam and avoiding steam. Take away a lot of heat, improve heating efficiency and reduce energy consumption.
