Novel rotor type fibre filtering material

Abstract

The invention relates to a filtering material used for water filtering. The invention discloses a novel rotary wing type fiber filtering material. The filtering material comprises fiber bundles and fiber nodes formed by fiber silks. The fiber nodes are the nodes formed by fiber silk buckles, the nodes at the cross positions of the fiber silks, the folding nodes of the fiber silks or the nodes formed by one fiber silk tied with other fiber silks. The fiber bundles and fiber nodes pass through the center of a rotary wing core; and the nodes of the fiber bundles and fiber nodes are enwrapped and bound by the rotary wing core. The filtering material has high binding strength and good back washing effects, and saves water and energy. The filtering material is suitable for the mechanized production. As the fiber bundles have a great volume ratio, the volumetric fraction of a filter bed is high and a filtering rate is high.

Description

technical field [0001] The invention relates to a filter material for water filtration. Specifically relates to a novel rotor type fiber filter material. Background technique [0002] In the traditional filtration process, the filter materials are mostly solid particle filter materials, such as sand, anthracite, activated carbon, ceramic balls, plastic rings, etc. The specific surface area of ​​this filter material is small, and the filter bed can hold a small amount of dirt, so the filtration accuracy Low, the filtering speed is slow. [0003] Synthetic fiber filter material has had greater progress than solid particle shape filter material, present synthetic fiber filter material is a kind of filter material (publication number: CN1273872A) that is made of fiber tow and tow knot as application number 00107758.9, Although the characteristics of large specific surface area and adjustable porosity of the filter bed have been utilized to overcome the defects of uneven densit...

[0003] Synthetic fiber filter material has had greater progress than solid particle shape filter material, present synthetic fiber filter material is a kind of filter material (publication number: CN1273872A) that is made of fiber tow and tow knot as application number 00107758.9, Although the characteristics of large specific surface area and adjustable porosity of the filter bed have been utilized to overcome the defects of uneven density of the spherical fiber filter bed and poor backwashing effect of the filter bed, it has not been able to solve the problem of fiber filter material winding. Filter grille, poor ability to adapt to different media, unsatisfactory backwashing effect, low utilization rate of filter bed, poor consolidation strength of filter core and fiber bundle (easy to fall off), etc.
