2025-01-21
The wedge-shaped cartridge is composed of “V”-shaped stainless steel wire and stainless steel support strips. The smooth surface of the cartridge is the filtration surface, and the slit is in the form of a strip belonging to the surface layer filtration. As a variety of forms of automatic filters (such as automatic backwashing, scraper self-cleaning, scraper disc self-cleaning, sucking self-cleaning filter) of the filter element is widely used in a variety of industries in the fluid filtration. Wedge wire filtration is made of stainless steel wire cold rolled from the screen bars, the support bars are welded by automated mining screen mesh production equipment, with high welding strength, seam uniformity, smooth surface, the filter surface is burr-free, angular, with the roundness. Due to the special wedge wire structure, compared with sintered mesh filter and other filter elements, it has the advantages of not easy to block, easy backwashing, long service life, and is a substitute for other filter elements. The filtration precision of the wedge-shaped filter element ranges from 0.025mm to 1mm, and the wedge-shaped filter element can realize fully closed automatic filtration, which can meet the food hygiene certification specifications.
