Project Name: battery material drying and organic solvent recovery project
Project Overview:
With global new energy, the rapid development of new materials, new battery materials with broad coated battery field has become a new field in recent years, the rapid development of the production process needs a revolutionary auxiliary equipment to complete, battery materials, special equipment also came into being.
(electromagnetic) materials for batteries (lithium iron phosphate, three yuan materials) the relevant characteristics, using SZG double cone rotary vacuum drying machine, dynamic FZG square vacuum drying unit two static drying series equipment and efficient recovery volume recovery device used by many customers, in actual use, the use of adequate data proof: the equipment can meet the requirements of the product drying, stable quality, but also for the solvent back of excellent performance, high recovery efficiency.
The system includes heating system, heat medium circulating system, drying system, dust filtration system, solvent recovery system, vacuum system.
Working principle：
Raw material conveying pump to the drying host drying tank body, at the same time, the heating medium by heating pipeline pump to sandwich dryer, drying machine for wall material by heat and is heated in the vacuum system under the action of water and gradually washed away by the drying purpose is achieved; in the raw material close to the drying stage, in order to prevent part of the powder is vacuum pump, the design of the special bag filter collection; organic solvent containing raw material through special condenser two stage condensation, the overall recovery rate of more than 95%.
Engineering advantages:
Drying process under the condition of negative pressure, so even if the solvent system, but the process is still very safe, and fast drying, the drying time of each batch of products is about 4 hours; drying process under reduced pressure, and set the drying temperature is relatively low, the vacuum pump continues to work, so the product stable quality; bag filter system is designed specially, so no flying dust; large area cooling two condensing device, the solvent recovery rate is high; the heating device can use hot water, steam, conducting oil heating; special bag filter and convenient; the whole unit less transmission components, and not in strong load condition therefore, the unit of long service life.
