In the lithium battery industry, filter presses are mainly used in the filtering, washing and wastewater treatment processes of lithium battery lithium mines, lithium extraction from salt lakes, positive electrode materials, graphite negative electrodes, silicon-based negative electrodes, PVDF resin materials, and lithium battery recycling.
How to choose lithium battery filter correctly？
In the preparation process of lithium battery materials, its production process is mostly based on hydrometallurgy, and the requirements for filter presses are more stringent than those in the mineral processing, environmental protection and other industries. This is particularly reflected in: high requirements for acid and high temperature resistance of the equipment, high automation requirements, low filter cake moisture content, water and energy saving, high filter cake effective washing rate, and conductivity must meet the standards. Traditional conventional filtration equipment cannot meet the needs of the lithium battery industry. For example, ordinary chamber diaphragm filter presses and vacuum belt filters have poor washing rates and high moisture content. They need to be combined with filtration-slurry washing-filtration and other combined processes, which consumes extremely high water and energy. Although vertical filter presses can operate continuously, they are expensive, have many fault points, and have extremely high operating and maintenance costs. The above equipment cannot meet the needs of the lithium battery industry for cost reduction, efficiency improvement, and green development. Against this background, Hzfilter washing filter presses and high-efficiency air-drying filter presses came into being as new lithium battery-specific filter presses.
Technical features of lithium battery filter press
- 1. Washing up to 99.5%, effectively removing impurities and other excess substances, and improving the recovery rate of valuable resources;
- 2. The average moisture content of lithium carbonate and ternary precursor materials is 8%-15%, and the subsequent drying cost is lower;
- 3. A single device can process up to 1,500 tons per day, greatly reducing the initial investment and subsequent operation and maintenance costs;
- 4. Water and energy consumption are at least 70% lower than that of a vertical filter press, and the amount of washing water is only 0.5-1.0 times the weight of the filter cake; Undercurrent 5. 5. equipment realizes classified liquid collection, which is safer and more environmentally friendly, and will not pollute the filter material body;
- 6. 0 reagent input, the filter cake is evenly washed in the machine to avoid secondary pollution;
- 7. The equipment's flow pipes, coatings, materials, etc. have a high anti-corrosion grade.
