Structure principle of wire wound filter element

In daily work, the use method and working principle of the wire-wound filter element are the foundation of its function in work. Before using the wire wound filter element, it is necessary to clearly grasp its structure principle.

The wire-wound filter element is made of polypropylene (PP) textile fiber roving, and various line arrangement procedures are set according to a specific density to form filter holes, which are precisely wound on a porous polypropylene (PP) skeleton.

The wire wound filter element product has a very high filtration pressure, and the filter pore size is large outside and small inside. It has an excellent deep filtration effect and can effectively remove suspended particles in the liquid.

The wire-wound filter element is also called a cotton core. The wire-wound filter element is mainly a textile fiber thread wound on a stainless steel porous skeleton to filter and remove impurities in the fluid;

It is generally suitable for filtration of low viscosity and low impurities. Compared with general purification equipment, it is a relatively deep filtration.

Wire wound filter

Commonly used precision of wire wound filter element: 0.5μm; common outer diameter of wire wound filter element: 60mm, 62mm; common inner diameter: 28mm, 30mm; common length: 10 inch, 20 inch, 30 inch, 40 inch, 1 meter.

The service life of the wire wound filter element is relatively long. For many filter elements, it is more prominent in terms of service life. It can effectively remove suspended particles, rust and other impurities in the liquid during the water treatment process;

Wirewound filter elements are mostly used for water treatment in household water and water treatment in electroplating plants and paint plants. It is widely used in the pretreatment of RO (reverse osmosis), NF (nanofiltration), UF (ultrafiltration), and EDI (electrodialysis) systems.

Water filter

What are the shortcomings of swimming pool filters in today's work?

For the existing swimming pool filter, there is room for improvement and progress in some aspects. What is the reason for the current situation? Let us take a closer look at the deficiencies of the existing swimming pool filter.

The existing swimming pool filter element generally includes an inner frame, a filter layer outside the inner frame, a top cover, and a bottom cover. Since the filter layer is a relatively soft structure, the entire pool filter element is supported by the inner frame.

Under the long-term impact of water flow, the requirements for the support strength of the inner skeleton are high, and the requirements for the hardness and durability of the inner skeleton are high, and it is necessary that it is not prone to deformation even after long-term use.

The existing production process of the inner skeleton is generally to produce a whole piece of mesh, then cut, and then bend the mesh to form a cylindrical structure;

Finally, the head and tail joints are glued together with glue. There are many procedures and low production efficiency. Moreover, such an inner skeleton has low support strength, low hardness, not strong enough and durable, and is prone to deformation after long-term impact by water flow;

Moreover, if glue is used for bonding, after long-term use, the glue will easily lose its adhesiveness, and the inner skeleton will easily disintegrate or deform and lose its supporting effect.

In addition, the top cover of the existing swimming pool filter element is generally a flat structure, and the structural design is relatively simple and fixed. When the filter needs to be installed, additional connecting parts are required for assembly, and the installation is not convenient.

Therefore, how to realize a simple and reasonable structure, high hardness of the inner frame, sturdiness and durability, not easy to deform under long-term impact of water flow, strong supporting effect, high production efficiency, simplified procedures, flexible and diverse structural design of the top cover, and can be based on actual conditions The pool filter element that needs to be selected and easy to install is a technical problem to be solved urgently in the industry.

The meaning of melt blown filter element in the filtration industry

Melt blown filter element is a relatively common filter element in the filtration industry. It is also one of the filter elements that have been around for a long time. Melt blown filter element can also be called PP cotton filter element. How is its use value reflected in work?

PP cotton filter element, also known as melt blown PP filter element, is a tubular filter element made of polypropylene particles through heating, melting, spinning, traction, and forming; if the raw material is mainly polypropylene, it can be called PP melt blown filter element .

The PP cotton filter element is made of fiber made of polypropylene resin and bonded by the fiber itself.

The layout of the filter element is that the outer fiber is thick, the inner fiber is thin, the outer layer is loose, and the tight mutation diameter of the inner layer is gradually tightened.

The common gradient deep filtration forms a three-dimensional filter residue function, which has the characteristics of high porosity, high rejection, large dirt holding capacity, large flow, and low pressure drop.

The PP cotton filter element is not only used in large quantities for water purification, but also has outstanding chemical compatibility and is suitable for the filtration of strong acids and alkalis. Strong dirt holding capacity, long service life and low cost. The PP cotton filter element has fine and uniform pore size and high filtration power.

Melt blown filter

Function and characteristics of PP cotton filter element:

It can effectively remove various particulate impurities in the filtered liquid;

It can be multi-layered and deep structure, which can hold large amount of pollution;

Large filtration flow and small pressure difference;

Does not contain any chemical adhesives, more hygienic and safer;

Resistant to acids, alkalis, organic solvents, oils, and has good chemical stability;

It integrates surface, deep, coarse and fine filtration; it has the characteristics of large flow, corrosion resistance, high pressure and low cost. It is used to block large particles such as rust, sand, and insect eggs in the water.
