With the rapid development of global new energy and new materials, new battery materials with a wide range of battery fields have become a new field, which will develop rapidly in recent years. Its production process needs revolutionary auxiliary equipment to complete, and special equipment for battery materials should also be shipped.
According to the relevant characteristics of battery (electromagnetic) materials (lithium iron phosphate, ternary materials, etc.), two drying series equipment of SZG double cone rotary dynamic vacuum drying unit and FZG square vacuum static drying unit and efficient recovery device for volume recovery are used. After practical application by many customers, sufficient use data prove that the equipment can fully meet the drying requirements of the product Seek, the quality is stable, and for the solvent look back performance is excellent, recovery efficiency is very high.
The system includes heating system, hot medium circulation system, drying system, dust filtration system, solvent recovery system and vacuum system.
The raw materials are pumped to the drying tank of the drying machine, and the heating medium is pumped to the heating interlayer of the drying machine through the pipeline pump. The raw materials are heated by the heat obtained from the drying machine wall, and the moisture is gradually removed under the action of the vacuum system to achieve the drying purpose. In the drying stage of raw materials, in order to prevent some powder from being pumped out by the vacuum pump, the special bag is designed The organic solvent contained in the raw material is condensed by a special condenser in the second stage, so that the overall recovery rate is more than 95%.
The drying process is carried out under the condition of negative pressure, so even if there is organic solvent medium, the process is still very safe, and the drying speed is fast, the drying time of each batch of products is about 4 hours; the drying process under the condition of reduced pressure, and the set drying temperature is relatively low, the vacuum pump is always working, so the product quality is stable; the system is designed with a special bag filter No dust flying; large area cooling of secondary condensing device, high solvent recovery rate; heating device can be heated by hot water, steam and heat transfer oil; special bag filter is easy to remove and wash; the whole set of unit has few driving parts and does not work under strong load conditions, so the unit has a long service life.
