Product Details

Sieve Bend Screens are ideal for sizing and dewatering applications to remove solids from liquids, or in solid/solid separation for dry feed situations.
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.
  


 Working principle

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.


Features & Advantage

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 life.


Application 


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.
