An industrial vacuum conveyor is a device that uses vacuum to convey plastic pellets. Its main components include a vacuum pump (which generates negative pressure), conveying piping, a separation filter, a control system, and a silo or receiving container. Coreal Machinery has compiled some information for your reference.
Common Problems in Plastic Pellet Conveying
- Pellet Breakage: Pellets collide and break during conveying.
- Blockage: Pellets accumulate or adhere, causing pipe blockage.
- Static Accumulation: Static electricity generated by friction between plastic pellets.
- Inefficiency: Slow conveying speed or high energy consumption.
- Contamination Risk: Foreign matter intrusion or pellet contamination.
Efficiency Improvement Solutions
1. Equipment Optimization
- Select the appropriate vacuum pump power based on pellet characteristics (size, shape, density).
- Use variable frequency drive to adjust conveying speed and negative pressure intensity.
- Select a pipe material suitable for plastic pellets (such as stainless steel or a special coating).
2. Conveying System Improvements
- Optimize pipe layout to reduce elbows and conveying distance.
- Use large-diameter pipes to reduce flow velocity and particle collisions.
- Install buffer devices to reduce particle impact.
3. Anti-static Measures
- Use anti-static piping and filters.
- Install static eliminators.
- Maintain appropriate ambient humidity.
4. Automated Control
- Integrate a PLC control system for automatic start and stop.
- Install a material level sensor for automatic refill.
- Fault alarm and automatic protection functions.
5. Optimize maintenance
- Clean filters and piping regularly.
- Inspect seals and connections.
- Establish a preventive maintenance plan.
