Abstract
The invention relates to a gradient filter element formed by using a porous ceramic filter element made of diatomite as a basal body and coating the basal body with a polypropylene spraying filter layer or a non-woven fabric filter layer. The gradient filter element is mainly used for water treatment equipment or other filter equipment. The polypropylene spraying filter layer has higher pollutant holding quantity so that the service life of gradient ceramics can be greatly prolonged.
Description
Technical field
The present invention relates to water-treatment technology field.It specifically is a kind of long-life type water treatment structure.
Background technology
Micropore ceramic filter element is a filtering material commonly used in the filter plant, and still, this micropore ceramic filter element filtering accuracy height not only can filter solid suspension, colloid etc., and the bacterium in can also trap water is easily stopped up by the pollutant of water kind, and the life-span is shorter.
Polypropylene melt blown filter and nonwoven filter core can be removed solid suspension in the water, colloid etc., have higher pollutant holding capability and long life-span, but filtering accuracy are not high, can't remove the bacterium in the water.
Usually polypropylene melt blown filter or nonwoven filter core and micropore ceramic filter element being used in combination is in the duct type water purification polypropylene melt blown filter or nonwoven filter core to be filtered as the first order, micropore ceramic filter element is as follow-up filtration, increased filtration progression like this, also increased manufacturing cost and small product size, its application has been subjected to certain restriction.
And in water dispenser, owing to be subjected to volume restrictions, can't realize classified filtering, and during single use micropore ceramics, the life-span is shorter.
Summary of the invention
Gradient filter element of the present invention is a kind of long-life type water treatment structure that provides at this state of the art.
The technical scheme that the present invention addresses the above problem is:
With the micropore ceramic filter element is matrix, and in its surface parcel layer of non-woven fabric, when water purification, by polypropylene or nonwoven filter course, by this filter course held back earlier by solid suspension in the water and colloid etc. for water, and the stopping state of micropore ceramic filter layer will alleviate greatly.
Description of drawings
Fig. 1 is a gradient filter element structural representation of the present invention, the water (flow) direction when direction of arrow among the figure is represented work.
The specific embodiment
Below in conjunction with concrete accompanying drawing gradient filter element of the present invention is described in detail, but is to be understood that the description does not here constitute limiting the scope of the invention.
Gradient filter element of the present invention wraps up layer of non-woven fabric on the micropore ceramic filter layer, the outside can be wrapped up with plastic deeping, and an end is fixed with the porose plastic fastening in center.
During work, when water passed through the nonwoven filter course, solid suspension wherein, colloid etc. were trapped, and had higher pollutant holding capability because nonwoven goes on foot.
Claims (6)
1, a kind of gradient filter element is a matrix with the high accuracy filtering material, the low high pollutant holding capability filtering material of precision of surface parcel one deck, and fixing.
2, gradient filter element as claimed in claim 1 is characterized in that: matrix can be the micropore ceramics filter material, also can charcoal other high accuracy filtering materials such as brilliant composite ceramics filter material.
3, gradient filter element as claimed in claim 1 is characterized in that: the low precision filtering material on surface can be a polypropylene, also can be other materials such as nonwoven, cotton thread.
4, gradient filter element as claimed in claim 1 is characterized in that: the low precision filtering material on surface can with spray, roll, other molding modes such as winding.
5, gradient filter element as claimed in claim 1 is characterized in that: its shape can be a tubulose, discoid, also can be other shapes such as double-side filtering tubulose, double-face circular disc.
6, gradient filter element as claimed in claim 1 is characterized in that: it can be a both ends open, also can be an end opening.
