Paper Recycling TRIZ Cases
- Hopper Posture Adjusting Unit for Paper Jam Prevention
A hopper posture adjusting unit guides non-flat strip-shaped sheets to align with the discharge port.
- Rotating Mesh Drum Fiber Separator Using Pneumatic Air Currents
Replacing wet processing with pneumatic separation, the rotating mesh drum prevents uneven fiber accumulation and maintains extraction efficiency.
- Recyclable Container Storage with Angled Transport Channels
Angled transport channels deposit recyclable containers into storage volumes to maintain suitable compression ratios.
- Deinking UV Prints with Rotary Disintegrator
A rotary disintegrator removes UV-curable inks from waste paper slurry, maintaining fiber integrity while improving deinking efficiency.
- Enzymatic Deinking of Recycled Paper Pulp
Neutral pH enzymatic treatment removes ink from recycled paper pulp while preventing fiber damage and yellowing caused by alkaline chemicals.
- Alternating Pressure Fibrous Material Impregnation
Vacuum and positive pressure cycles force liquid into collapsed fiber cavities, increasing moisture content and pulp bulk density.
- Rope Winch Control for Waste Paper Pulping
Adjusting roller contact pressure based on plait speed prevents jamming and slip-back during waste paper defibration.
- Waste Paper Dissolution Routing for Energy Reduction
Segmenting waste paper feed into streams optimizes energy consumption while maintaining versatility across varying material qualities.
- Recycled Paper Brightness Without Optical Brighteners
Recycled paper forms from contaminated waste using hydrogen peroxide for brightness, eliminating costly optical brightening agents.
