Ternary precursor/lithium hydroxide disc dryer

Ternary precursor/lithium hydroxide disc dryerEquipment Overview:

The disc dryer developed by our company for materials such as lithium chloride, carbonic acid, lithium hydroxide, nickel hydroxide, cobalt carbonate, and ternary materials produced by centrifuges is a multi-layer fixed hollow heating circular loading tray, rotary rake stirring, and vertical continuous heat conduction drying equipment developed through continuous improvement based on gap stirring and transfer to the dryer, integrating a series of advanced technologies. As the heat required for drying the device relies on indirect heating through thermal conduction, the drying process does not require or only requires a small amount of gas to remove moisture. Greatly reducing the heat loss carried away by the gas and improving the heat utilization efficiency, it is an energy-saving drying equipment.

principle

The wet material is continuously added to the first layer of drying disc on the upper part of the dryer by the feeder, and the rake arm with rake blades rotates to continuously flip the material. The material flows along an exponential spiral over the surface of the drying disc, and the material on the small drying disc is transferred to the outer edge, where it falls onto the outer edge of the large drying disc below. The material moves inward on the large drying disc and falls into the next layer of small drying disc from the middle feeding port. The drying plates of different sizes are arranged alternately up and down, allowing the material to flow continuously through the entire dryer. A hollow drying tray is filled with heating medium, which includes saturated steam, hot water, and thermal oil. The heating medium enters from one end of the drying tray and exits from the other end. The dried material falls from the last layer of the drying tray to the bottom of the shell, and is finally transported to the discharge port for discharge. Moisture escapes from the material and is discharged through the dehumidification port located on the top cover. The moisture in the vacuum disc dryer is extracted through the vacuum pump port located on the top cover. Dry materials discharged from the bottom layer can be directly packaged. By using auxiliary equipment such as finned heaters, solvent recovery condensers, bag filters, dry material mixing mechanisms, and induced draft fans, the production capacity of drying can be improved. Drying paste like and heat sensitive materials can facilitate solvent recovery and enable pyrolysis and reaction operations.
