Wedge wire filter element (also called wedge screen filter element or wedge wire mesh filter element) is a metal structure filter element commonly used for solid-liquid separation, filtration, and screening. It is named for its special structure made of wedge-shaped metal wires. This filter element has high structural strength, stable filtration accuracy, high temperature resistance and corrosion resistance. It is widely used in water treatment, petrochemical, food and beverage, papermaking, pharmaceutical and other industries.
Anping Haopeng Wire Mesh Co., Ltd. is a Chinese manufacturer specializing in galvanized wire products, welded wire mesh and mesh fence, perforated metal sheet, expanded metal, stainless steel filter element, wedge wire filter element.
Advantages of wedge wire
1. High strength and durability
High pressure resistance: Wedge wire material is usually made of stainless steel (such as 304, 316L, etc.), which makes it have strong pressure resistance and can be used for a long time under high pressure environment.
Corrosion resistance: Due to the special nature of the material, wedge wire can resist the erosion of various corrosive media such as acids and alkalis, and adapt to complex industrial environments.
2. Stable filtration accuracy
The grid structure of wedge wire makes the filtration accuracy very stable. Since the gap size between the wires is fixed and not easy to deform, its filtration effect remains consistent after long-term use.
This stability is very suitable for occasions where precise control of filtration effect is required, such as chemical, pharmaceutical and other industries.
3. Not easy to clog
Self-cleaning: The special structure of the wedge wire, especially its trapezoidal cross-section, can effectively prevent impurities from clogging the mesh. When the fluid passes through, impurities are easily carried away by the flow, especially when filtering liquids, which can avoid frequent cleaning of the filter.
Since its flow direction is usually from outside to inside or from inside to outside, it can effectively reduce the probability of clogging.
4. Longer service life
Repeated cleaning: The mesh size of the wedge wire structure is uniform, it is not easy to be damaged during cleaning, and it can withstand a large backwashing pressure, so it can be cleaned repeatedly to extend the service life of the filter element.
In many industrial applications, filters often need to be replaced or cleaned, and the wedge wire filter element reduces the frequency of replacement and reduces operating costs due to its durability.
5. High flow capacity
Due to the mesh structure of the wedge wire, the fluid has low resistance during filtration and can provide a higher flow capacity. This makes the wedge wire filter element have advantages in large flow and continuous operation application scenarios, such as high flow applications commonly found in water treatment and petrochemicals.
6. Wide adaptability
Wedge wire filter elements can adjust the gap, thickness and material between the wires according to different needs, and are suitable for solid filtration of various particle sizes.
Suitable for a variety of industries, including water treatment, oil and gas, food processing, papermaking, chemical industry, etc., to meet the needs of different industries.
