Paper Material Treatment TRIZ Cases
- Tubular Fractionation for Elongated Fibers with Self-Clearing Flow
A conical outlet and annular channel use hydrodynamic flow to separate elongated fibers at high throughput while limiting blockage.
- Conical Drum Element Flow Channels for Pulp Screening
Segmented flow channels with decreasing cross-sections create pressure pulsations that prevent clogging and maintain high screening capacity.
- Combi-screening Arrangement for Cellulose Pulp with Secondary Inlet
A cellulose pulp screening arrangement uses a secondary inlet to route accept fractions directly to fine screens.
- Curved Rotor Blades for Pulp Screen Energy Reduction
Curved rotor blades with wing-shaped profiles reduce energy consumption and pressure pulses while extending screen basket service life.
- Inclined Rotor Sieve for Fibrous Stock Screening
An inclined rotor sieve prevents blockages by generating rotational flow that separates impurities from fibrous stock suspensions.
- Removable Screening Unit Axial Slot Adjustment
Removable screening unit features adjustable axial slots for precise inspection and maintenance outside the main arrangement.
- Disc Filter Asymmetric Corrugated Profile for Fleece Detachment
Asymmetric corrugated filter plates with wider valleys enhance drainage surface area and fleece layer detachment in rotating disc filters.
- Curved Filter Sector With Polygonal Base For Disk Filters
Curved polygonal structures on the filter plate increase surface area without adding mass, reducing mechanical loads on the hollow shaft.
- Pressure Screen Rotor Inlet Positioning for Pulsation Reduction
Positioning the suspension inlet close to the rotation axis reduces energy consumption and pulsations by generating necessary rotational flow before the rotor.
- Rotorless Knotter Inversion for Pulp Plugging
Rotating hydrofoils prevent plugging in a stationary screen knotter, eliminating dilution and reducing equipment size.
- Screen Cylinder Accept Channel Curvature
Curved accept channel reduces pressure loss and fiber spinning in screening processes.
- Undulated Rotor Element for Screening Apparatus
Undulated rotor elements induce three-dimensional fluid activity to weaken blockages, allowing slower rotational speeds and reduced power consumption.
- External Circulation System for Screening Reject Separation
An external circulation system dilutes pulp flow to separate heavy particles into a dedicated junk trap.
- Pressure Screen Dilution Water Rejection Control
Adding 0.8 to 3.5 times reject volume water locally reduces thickening, lowers motor load, and prevents plugging.
- Fibrous Suspension Purification via Single Pump Extraction
Single pump upstream manages fibrous suspension flow through sorting stages without intermediate valves.
- Trichome Separation Process Using Water and Sieves
A trichome separation process uses water immersion and multiple sieve stages to float fibers from non-trichome materials.
