Sieve Bend Screens are ideal for sizing and dewatering applications
to remove solids from liquids, or in solid/solid separation for dry
Sieve Bend Screens can be manufactured in a variety of widths, arc
lengths, apertures or wedge wires to suit the flow rate and
material being separated. Although most applications require Static
Sieve Bends, "Cross Flow", "With Flow" and "Vibrating" Sieve Bends
can also be manufactured.
The main body of the waterpower slanted screen is the stainless
wedge wire sieve bend with arc surface or flat surface. When the
sewage water flows to the slanted screen evenly through the
overflow dam, the solid matters will be intercepted and the
filtered water will be discharged through the screen slot. At the
same time, under the effect of waterpower, the solid maters will be
pushed to the bottom of the screen to discharge. So it can reach
the effect of solid-liquid separation.How it works
The feed slurry is directed vertically and tangentially over the
full width of the upper screen surface. The slurry flows down the
concave surface at right angles to the openings between wedge
profiled wires. Due to the drag on the slurry passing over the
wedge wire, a thin layer on the underside is deflected and passes
out between the wires. The fact that the size of particle passing
through the screen is always smaller than the opening, gives the
screen good non-clogging properties.
In a typical feed situation the leading edge of the wedge wire
removes the water and fine particles through the screen up to the
cut point size, as the oversized particles move across the top of
the screen. Static Sieve Bends require little or no maintenance in
their operation and need only small head heights to operate.
1. Working with the water gravity, no energy consumption
2. High water treatment capacity
3. Not easy to be blocked and easy to clean
4. Using stainless steel, it has high mechanical strength and long
1. To remove the solid substance such as suspended matter, floater
and precipitate in the waste water treatment of slaughter, leather,
paper, sugar, wine-making, food processing, textile, printing and
dyeing, petrochemical industry.
2. To recycle useful material such as fiber in paper, alcohol,
starch and food industry.
3. Pretreatment of sludge and channel cleanout.
