Detailed Description
1. Challenges of Solid-Liquid Separation in Lithium Carbonate Production
In the process of extracting lithium carbonate from lithium ores (such as spodumene and lepidolite), multiple filtration and washing steps are involved, such as:
- Solid-liquid separation after ore leaching: After acid-base leaching and precipitation of lithium ore, a lithium-containing solution and a large amount of impurity solids are produced, requiring efficient filtration to extract pure lithium solution.
- Washing and filtration after lithium carbonate crystallization: The precipitated lithium carbonate crystals need to be washed multiple times to remove impurities, ensuring a high-purity product.
- Waste liquid treatment and resource recovery: The waste liquid generated during production still contains lithium and other recoverable elements. A reasonable filtration process can improve resource utilization and reduce environmental pollution.
In these process steps, traditional filtration methods often face the following challenges:
- Low filtration efficiency: Ordinary filter cloth may lead to insufficient permeability or blockage, affecting filtration speed and capacity.
- Difficult filter cake detachment: Lithium carbonate crystals are small and prone to clumping, making it difficult to peel off the filter cake, affecting continuous production.
- High corrosion resistance requirements for filter cloth: The leaching and washing processes involve strong acid and strong alkaline environments, and the filter cloth must have excellent chemical corrosion resistance.
- Insufficient wear resistance of filter cloth: Long-term operation can easily lead to wear of the filter cloth, increasing maintenance costs and downtime.
2. Advantages of Horizontal Vacuum Belt Filter
The horizontal vacuum belt filter (HVBF) is a continuously operating vacuum filtration device widely used in the production of lithium battery new energy materials, with main advantages including:
- Efficient continuous filtration: Driven by vacuum negative pressure, it continuously performs solid-liquid separation, avoiding the inefficiency of intermittent filtration.
- Multi-stage washing function: Multi-stage filter cake washing can be completed on the same device, improving the purity of lithium carbonate.
- Controllable filter cake thickness: The thickness of the filter cake can be adjusted according to process requirements, optimizing the filtration effect.
- High degree of automation: With an advanced control system, it can achieve fully automatic operation, improving production efficiency.
However, the filtration performance of the horizontal vacuum belt filter largely depends onthe selection and matching of industrial filter cloth..
