Abstract
The utility model relates to a gradient filtering core, which is a filtering apparatus of water treatment. The utility model is composed of a central skeleton and filtering layers, wherein the filtering layer is composed of more than two layers of gradient filtering cores, wherein filtrating pore diameter of the gradient filtering cores form degression from outer part to inner part. Because the gradient filtering cores form multilayer gradient filtration, the filtration accuracy of each gradient filtering layer with different pore diameter is matched. The utility model has the advantages of sufficient filtration, small filtration resistance, strong sewage blocking prevention capability, high integral filtering core utilizing rate, and long service life.
Description
Technical field
The utility model relates to a kind of Filters of water treatment.
Background technology
The aperture of traditional its filter course of filter core is a uniformity, in use, stops up in case its top layer is filtered impurity, causes filtration pressure difference to increase, and promptly will change integral filter core.Thereby the filter core of traditional structure only utilized the top layer, and utilization rate is low, and service life is short, wastes bigger.
Summary of the invention
The technical problem that the utility model quasi-solution is determined is for overcoming the shortcoming of above-mentioned traditional filter core, and the filter core of the new structure of a kind of overall utilization rate height, long service life is provided.
Art designs scheme of the present utility model is: by the filter core that center framework and filtering layer constitute, the gradient filtering layer that its filtering layer is tapered off by its pore size filter of the ecto-entad more than two layers is formed.
Technique effect of the present utility model: filter because filter core is multi-gradient, the gradient filtering layer filtering accuracy in variant aperture brings out the best in each other, and filters fully, and filtration resistance is little, and the stifled ability of anti-soil is strong, integral filter core utilization rate height, long service life.Facts have proved that the more traditional filter core of the utility model can improve the service life rate more than 80%.
Description of drawings
Accompanying drawing is a general structure schematic diagram of the present utility model.
The specific embodiment
Embodiment, center framework 1 is made by engineering plastics or stainless steel; Be centered around filtering layer 2 on the center framework 1 by three layers of gradient filtering layer 2 ' 2 " 2 form; from inside to outside; gradient filtering layer 2 ' pore size filter be 3u; thickness of filter bed is 4mm; gradient filtering layer 2 " pore size filter be 5u, thickness of filter bed is 6mm, and the pore size filter of gradient filtering layer 2 is 10u, and thickness of filter bed is 8mm; They all adopt polypropylene to spray molten fiber and make.The utility model with former common be that the thick polypropylene of the 18mm of 3u sprays single filtering layer filter core that molten fiber filtering layer 2 constitutes and compares by center framework 1 and aperture, under identical technology service condition, after tested, the former is 3896 hours service life, the latter is 2160 hours, and the utility model has improved service life more than 80%.
Claims (1)
1, a kind of gradient filter element has center framework (1) and filtering layer (2), it is characterized in that gradient filtering layer that filtering layer (2) is tapered off by its pore size filter of the ecto-entad more than two layers is formed.
