Moving Filtering Element Filters TRIZ Cases

Separating precoat formation from filtration prevents pre-layer particles from contaminating filtered liquids in purity-critical suspension processing.

Peripheral support rings, scraper members, and backwash improve slurry filtration by easing cake removal, lowering fluid resistance, and reducing maintenance.

A rotating cover brings multiple filter modules to one working position, increasing sample throughput without the space and movement burden of serial collectors.

A one-piece lattice frame supports and tensions plastic filter cloth, balancing drum-panel strength, flexibility, service life, and cost.

Mounted on carrier chain links, non-metallic plates reduce water bypass and simplify traveling water screen maintenance.

Inwardly sloping walls and a covering flap increase filtering surface area while preventing liquid splashing between cells.

A composite drum filter uses a rigid inner base body and fluid-tight outer functional body to separate structural support from chemical protection.

A disc filter fixing node uses an elongated plate and through hole to secure filtration elements with a disconnectable unit.

Segmented settling and rinse zones prevent fine sand suspension in rinse water, maintaining separation efficiency.

Mechanically coupled drag bars remove accumulated particles from the tank bottom to prevent system jamming and eliminate manual cleaning downtime.

A microparticle filter uses a rotatable cage and transfer member to separate solid particles from effluent.

Duplex stainless steel cover plates span rib elements to reduce wetted surface area, resolving vacuum efficiency losses from excessive support structures.

A drum filter uses compression means to adjust liquid levels, maximizing the active filtration surface area within a compact housing.

Segmented filter elements attach to a stable spoked wheel, resolving the trade-off between structural rigidity and maintenance complexity.

Riveted sheet metal frames replace heavy drums in rotary disc filters, cutting weight and manufacturing costs.

A traction system compensates axial forces between rotating filtration plates to minimize mechanical friction.

Periodic projection of elastically deformable rotating plates prevents structural damage while maintaining efficient liquid extraction.

Permanent joining of the framework and filter cloth eliminates complex fastening organs, reducing leakage risk and maintenance time.

A rotating perforated screen compacts solids against its surface while liquid passes through.

Undercut grooves secure reinforced filter medium edges, eliminating seams that cause leakage and reducing fixation time.

Endless drive belts mount the central tube on pulleys above fluid level, eliminating bearing exposure to water and impurities that cause failure.

Passive-rotation filter elements use fluid impact to rotate, preventing scaling and corrosion while eliminating replacement costs.

Intermediate lamellae seal gaps between rotating filter plates, removing solid matter that causes blockages and maintains filtration efficiency.

Frustum-shaped walls merge into the rotor frame, eliminating a separate drum to reduce device volume and manufacturing costs.

Variable weave density reduces mesh tear and material loss during high-pressure continuous filtration.

Snap-in cap strips secure rotary drum filter covers, eliminating labor-intensive welding and simplifying field maintenance.

A backwash filter uses a rotatable discharge channel to clean the filter body.

Relocating receiver chutes to the downward rotor side prevents fibre thickening by diluting material with flushing liquid.

Undulating sieve fields on a circulating screening belt increase effective area and dirt retention, reducing hydraulic resistance in liquid flow channels.

Segmented filtration chambers with dynamic controllers reduce equipment duplication and energy consumption by activating only necessary units during peak flow.
