Pulp De-Watering TRIZ Cases

Divider plates guide filtrate by gravity into drainage holes, raising rotary drum filtration capacity without weakening the drum shell.

A screw compression process separates liquid from aqueous lignocellulosic suspensions to enable solid phase handling.

Segmented container parts create integrated teeth to prevent suspension rotation, maintaining dewatering efficiency without adding internal bars.

Segmented dewatering stabilizes pulp consistency by using a stuffing screw with drainage openings to remove water without additional energy.

Recirculating pulp screening rejects to the impregnation step reduces shive content while lowering refining energy consumption.

Angled slots in a vacuum dewatering box cover reduce fabric wear and energy consumption by optimizing fluid flow paths.

A twin wire press uses a bottom frame to support roll assemblies without overhead structures.

Pressure filtration concentrates fibril cellulose by removing liquid, bypassing impermeable membrane formation that blocks conventional drying methods.

Mechanical disc refining separates non-cellulosic components to reduce energy consumption and waste in sustainable packaging production.

Recycling pulp screening rejects to the impregnating step eliminates separate treatment lines, reducing energy consumption and equipment complexity.

Adding a specific cationic polymer to the fiber suspension enhances inter-fiber bonding, maintaining dry strength despite shorter recycled cellulose fibers.
