Battery material drying and organic solvent recovery project

  Project Overview

With the rapid development of global new energy and new materials, new battery materials in the field of widely used batteries have also become an emerging field. In recent years, they will develop rapidly, and their production process requires revolutionary auxiliary equipment to complete. Our developed battery material specialized equipment has also been put into operation.
In response to the relevant characteristics of battery (electromagnetic) materials (lithium iron phosphate, ternary materials, etc.), our company has developed two drying series equipment, SZG double cone rotary dynamic vacuum drying unit and FZG square vacuum static drying unit, as well as an efficient recovery device for volume recovery. After numerous customers' practical applications, sufficient usage data has proven that this equipment can fully meet the drying requirements of the product, with stable quality and excellent solvent recovery performance, resulting in high recovery efficiency.
The system includes a heating system, a heat medium circulation system, a drying system, a dust filtration system, a solvent recovery system, and a vacuum system.

Technical process (flowchart): Call to discuss in detail.

  working principle

The raw materials are transported to the drying tank of the drying machine through a conveying pump, and at the same time, the heating medium is transported to the heating interlayer of the dryer through a pipeline pump. The raw materials are heated by obtaining heat through the wall of the drying machine, and gradually remove moisture under the action of the vacuum system to achieve the drying purpose; To prevent some powder from being extracted by the vacuum pump during the drying stage of the raw materials, a specially designed bag filter is used for collection; The organic solvents contained in the raw materials are condensed in a special condenser for the second stage, resulting in an overall recovery rate of over 95%.

  Advantages reflected

The drying process is carried out under negative pressure conditions, so even if it contains organic solvent medium, the process is still very safe and the drying speed is fast. The drying time for each batch of products is about 4 hours; The drying process is carried out under reduced pressure conditions, and the drying temperature is set relatively low. The vacuum pump is always working continuously, so the product quality is stable; The system is designed with a specially designed bag filter, so there is no dust flying; The large-scale cooling of the secondary condensing device results in a high solvent recovery rate; The heating device can use hot water, steam, or thermal oil for heating; Specially designed bag filter for easy disassembly and cleaning; The entire unit has fewer transmission components and does not operate under high load conditions, resulting in a long service life of the unit.

  patent application
