Wedge wire screen, also known as Johnson mesh screen, is mainly divided into two types: Screen tube and Screen plate. The wedge wire screen filter element is composed of a wedge-shaped or "V"-shaped stainless steel profile wire and a stainless steel support rod. The smooth surface of the filter element is the filter surface, and the gaps are strips. As the best filter element for various forms of automatic filters (such as automatic backwashing, scraper self-cleaning, scraper self-cleaning, and suction self-cleaning filters), it is widely used in fluid filtration in various industries. It is widely used in the filtration of the petrochemical industry, coal mine, well drilling, sewage treatment, food, pharmaceutical, papermill, environmental protection, etc.
Structural principle: The stainless steel wedge wire screen filter is a metal mesh-shaped structural element used for screening and filtering. It has high strength, rigidity, and load-bearing capacity, and can be made into a rigid screening and filtering device of various shapes.
Product Features
1. The continuous gap greatly increases the flow area, so it can be in good contact with the aquifer.
2. The V-shaped screen bar structure forms a wedge-shaped gap to avoid clogging and ensure smooth circulation.
3. Long service life, continuous pores can be used effectively for a long time, Reduced maintenance costs.
4. The wedge wire filter pipe has a strong structure, high porosity, and precise gap size.
5. The wedge wire filter tube is easy to backwash, has a long service life, reliable quality, and low overall cost.
