A stainless steel wedge wire bend screen filter is a kind of filtration equipment made of stainless steel wedge-shaped wires. It is also known as a curved sieve bend screen.
Structure and Materials
Structure：The filter is composed of stainless steel wedge-shaped wires and support bars, which are welded together. The wedge-shaped wires are usually arranged in a spiral or parallel manner to form a curved surface, and the gaps between the wires are uniform, which can effectively prevent blockage.
Materials：Commonly used materials include stainless steel 304, 304L, 316, 316L, etc. These materials have excellent corrosion resistance, wear resistance, and high - temperature resistance, which can ensure the service life and performance of the filter in various harsh environments.
Features
High - precision filtration：The filtration accuracy can generally reach 20 microns to 3000 microns, and different filtration accuracy requirements can be met by adjusting the gap size between the wedge - shaped wires.
Large filtration area：The curved structure can increase the effective filtration area, improve the filtration efficiency, and have a large flow - through capacity.
Good anti - blockage performance：The V - shaped wire structure makes the debris not easy to accumulate in the gaps, and the self - cleaning ability is strong, which is not easy to be blocked.
Strong and durable：Made of stainless steel materials and welded as a whole, it has high strength, good pressure resistance, and is not easy to deform.
Application areas
Water treatment：It is widely used in water treatment processes such as raw water intake, sewage treatment, and industrial wastewater treatment to filter out suspended solids, particles, and other impurities in water.
Mineral processing：In the mineral processing industry, it is used for screening, dewatering, and desliming of ores to improve the quality of concentrates.
Coal washing：Used in coal washing plants to separate coal and gangue, and remove impurities in coal to improve coal quality.
Related product forms
Filter cartridges：It is often made into filter cartridges, which are used in Security Filter and other equipment, and have the characteristics of large dirt - holding capacity and long service life.
Filter baskets：Filter baskets made of stainless steel wedge - wire bend screens are used in some occasions where solid - liquid separation is required, such as chemical reaction and filtration tanks.
