Challenge:
Chemical companies often face challenges in achieving dust-free production processes when handling powders. Traditional methods of powder transfer and processing can generate significant dust, posing safety and environmental concerns.
Solution:
Shanghai Youwei Mechanical and Electrical Co., Ltd. implemented a chemical powder vacuum feeder and screening system for a client, enabling:
- Dust-free transfer: The vacuum feeder uses negative pressure to convey powders through enclosed pipelines, preventing dust leaks and contamination.
- Efficient screening: The integrated screening system ensures consistent particle size and removes unwanted materials, further enhancing product quality.
Benefits:
- Improved safety: The dust-free operation minimizes the risk of respiratory issues and explosions associated with airborne particles.
- Enhanced product quality: Consistent particle size and removal of impurities contribute to a superior end product.
- Increased efficiency: The automated system optimizes production processes, leading to improved output and reduced labor costs.
Project Details:
- Materials: Chemical powders (acidic, alkaline, flammable, explosive)
- Conveying distance: 22 meters
- Conveying height: 6 meters
- Material bulk density: 1.2 g/cm³
- Conveying capacity: 2 tons per hour
Process Flow:
- Material discharge: Chemical powder is discharged from a double cone dryer.
- Vacuum transfer: The powder enters a special pipeline and is conveyed to a silo by the vacuum feeder.
- Metering and screening: A rotary valve below the silo feeds the powder evenly onto a vibrating screen for size classification.
- Recirculation and packaging: Screened materials fall back into the pipeline and are transported to the packaging system via the vacuum feeder.
