Abstract
The utility model discloses a highly efficient filter element. A layer of prefiltration film, a layer of middle filtration film and a layer of high-precision filtration film are arranged on the prop of the filter element. The layer of high-precision filtration film is positioned in the innermost place wrapped up in the prop; the layer of middle filtration film is wrapped on the layer of high-precision filtration film; and the layer of prefiltration film is covered on the layer of middle filtration film. The diameter of the filter hole of the layer of prefiltration film is greater than the diameter of the filter hole of the layer of middle filtration film, which is in turn greater than the diameter of the layer of high-precision filtration film. The utility model is provided with three layers of filtration film on the prop, which can effectively filter the liquid layer by layer, so that the effectiveness of filtering the liquid is greatly improved. In addition, because of adopting the structure of three layers of filtration film with different diameters of the filter holes, the capability of holding filth is also greatly improved and the filter element is not easy to be blocked and more convenient to be washed. The utility model has not only the advantages of high efficiency of filtration, strong capability of holding filth and not easy to be blocked, but also the advantages that the filter element is easy to be washed and has a long service life.
Description
Technical field:
The utility model and a kind of efficient filter core that is used for filter liquide belong to liquid filtering filter core technical field.
Background technology:
Of the prior artly be used for the filter core that filter liquide is used, general all is at the filter membrane that is provided with the single filter opening diameter of parcel one deck on the filter core pillar of apopore, the filter core of this structure, shortcoming such as exist that filter efficiency is lower, accuracy is not high, polluted force is strong, filter core stops up easily and easy cleaning and service life is not short.Therefore, existing filter core makes in use, and its result of use still is not ideal enough.
Summary of the invention:
The purpose of this utility model is: provide that a kind of filter efficiency is higher, polluted force is strong, filter core is difficult for stopping up and clean easily, the efficient filter core of long service life, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: it comprises the filter core pillar 4 that is provided with apopore, on filter core pillar 4, be provided with coarse filtration rete 1, middle filter membranous layer 2 and high-accuracy filter membranous layer 3, high-accuracy filter membranous layer 3 is located at the innermost layer and is wrapped on the filter core pillar 4, middle filter membranous layer 2 is wrapped on the high-accuracy filter membranous layer 3, coarse filtration rete 1 is wrapped on the middle filter membranous layer 2, and the filter opening diameter of coarse filtration rete 1 is greater than the filter opening diameter of middle filter membranous layer 2, and the filter opening diameter of middle filter membranous layer 2 is greater than the filter opening diameter of high-accuracy filter membranous layer 3.
The filter opening diameter of coarse filtration rete 1 is 10～100 microns, and the filter opening diameter of middle filter membranous layer 2 is 2～8 microns, and the filter opening diameter of high-accuracy filter membranous layer 3 is 0.5～1.0 micron.
Owing to adopted technique scheme, the utility model is provided with coarse filtration rete, middle filter membranous layer and high-accuracy filter membranous layer three metafiltration films on filter core pillar 4, this three metafiltration film can successively filter liquid effectively, thereby improved filter efficiency greatly to liquid, in addition, because the utility model has adopted the different filter membrane structure in three layer filtration aperture, so improved its water environment capacity effectively, and make filter core be difficult for stopping up, and make its easier cleaning.Therefore, the utility model compared with prior art, the utility model has not only that filter efficiency height, polluted force are strong, the not susceptible to plugging advantage of filter core, but also has the advantage of easy cleaning, long service life.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment:
Embodiment of the present utility model: the filter core pillar 4 that is provided with apopore can adopt plastic production by traditional approach, during making, on filter core pillar 4, superscribe coarse filtration rete 1 respectively, middle filter membranous layer 2 and high-accuracy filter membranous layer 3, high-accuracy filter membranous layer 3 is prevented also directly being wrapped on the filter core pillar 4 in the innermost layer, middle filter membranous layer 2 is wrapped on the high-accuracy filter membranous layer 3, coarse filtration rete 1 is wrapped on the middle filter membranous layer 2, and make the filter opening diameter of the filter opening diameter of coarse filtration rete 1 greater than middle filter membranous layer 2, the filter opening diameter of middle filter membranous layer 2 is greater than the filter opening diameter of high-accuracy filter membranous layer 3; Needs according to using can be controlled at the filter opening diameter of coarse filtration rete 1 10～100 microns during making, and the filter opening diameter of middle filter membranous layer 2 is controlled at 2～8 microns, and the filter opening diameter of high-accuracy filter membranous layer 3 is controlled at 0.5～1.0 micron; Coarse filtration rete 1, middle filter membranous layer 2 and high-accuracy filter membranous layer 3 can adopt the polypropylene material to make, and can adopt traditional production method to be made into melt-blown filter or wire-wound filter core.
