The wound filter element is different from the folded filter element and melt blown filter element. Its structure is relatively unique. It forms the wound filter element by winding the textile fiber material on the skeleton. Its filtering accuracy is controlled according to the winding density.
In the structural design, the pore diameter of the wound filter element is large outside and small inside, which makes it have a prominent effect in deep filtration.
The process of making wound filter element is not complicated. It is mainly made by winding textile fiber yarn with filtration performance on the porous skeleton. There are many kinds of materials for these yarns, including three common ones: polypropylene fiber, absorbent cotton fiber and acrylic fiber.
When winding the yarn on the skeleton, the winding filter element with different accuracy can be made by changing the dilute density and tightness of the yarn. The filter element of this deep filtration is generally aimed at the filtration of water with less impurities and low particle content.
The structure of the wound filter element is designed into a honeycomb form with sparse outside and dense inside, which ensures its role and advantages in removing suspended solids, impurities, particles and other impurities in the liquid, and more shows its own product characteristics and properties.
Like many water filter elements, wound filter elements are used in many industries and fields. Common include:
① Food and beverage processing industry, such as mineral water, syrup, alcohol, edible oil, etc.
② Pharmaceutical processing industry, such as alcohol, dispensing water, injection, tetracycline liquid, etc.
③ Petroleum and chemical industry, such as common cosmetics, drugs, chemicals, inks, coatings, acrylic raw materials and so on.
④ Electronic processing industry, such as electroplating, printed circuit board, etc.
⑤ Industrial oils, such as hydraulic oil, lubricating oil, cutting oil and other industrial oils.
The main advantages of wound filter element are as follows:
1、 The wound filter element adopts a good design concept and adopts a small inner diameter and a large outer diameter to form a good filtering effect;
2、 The wound filter element has good pollution receiving effect, not only has large flow, high filtration accuracy, but also does not have secondary pollution, and its service life has been extended to a certain extent;
3、 The wound filter element can wind a variety of materials on the skeleton, and different materials have different filtration effects and filtration accuracy. For the liquid to be filtered, the wound filter element of corresponding materials is used for filtration, so that the filtration can achieve incredible effect.
