A kind of modified composite filter element
Technical field
The utility model is related to filtering apparatus for drinking water manufacturing technology field, and in particular to be a kind of to be drunk for filtering
The modified composite filter element of water.
Background technology
The threat of drinking water pollution problem, particularly heavy metal ion pollution, increasingly cause the height weight of various circles of society
Depending on.At present, in general device for purifying potable water, the problem of purification style is single, clean-up effect is poor be present, filter core is as drinking water
The core component of purifier, the properity of filter core influence the using effect of purifier, and existing filter core is mainly single
Material is made, such as active carbon filter core, single external pressure milipore filter, and its clean-up effect is bad, and simply several filter cores are connected,
Although the clean-up effect of drinking-water can be improved, the problems such as space-consuming is big, assembling is complicated, joint quantity is more be present.
Utility model content
The purpose of this utility model is to provide a kind of modified composite filter element, and each filter membrane assembling is simple and convenient, filtering effect
Fruit is effectively and safe.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of modified composite filter element, including filter element body and the filter cover for installing the filter element body, the filter
Core body includes that charcoal earthenware film layer, ion-exchange fibre film layer and the ultrafiltration film layer filtered successively by filter medium can be made.
The charcoal earthenware film layer, ion-exchange fibre film layer and ultrafiltration film layer ecto-entad are set gradually, adjacent
It is intersegmental away from setting that one is mutually sticked or be spaced between filter membranous layer.
The charcoal earthenware film layer is substituted by the NACF film layer;
The ion-exchange fibre film layer by one kind in ion exchange activity Carbon fibe film layer and anionic particle layer or
The combination replacement that two kinds of person;
The ultrafiltration film layer is surpassed by filtering meshes, nucleopore film layer, nonwoven layer, PP film layers, PE ultrafiltration thing film layers and PVDF
One or more combination replacements in filter membranous layer.
The shape of the filter cover is adapted with the outline of the upper end of the charcoal earthenware film layer, the charcoal earthenware film layer
Upper end and the filter cover week along being tightly connected.
The madial wall of the ion-exchange fibre film layer and the charcoal earthenware film layer is brought into close contact.
Liquid outlet is provided with the filter cover, the liquid outlet is hickey.
Separation net is provided with the liquid outlet and fixed by a tabletting in the filter cover.
Be separately provided for installing in the filter cover charcoal earthenware film layer, the ion-exchange fibre film layer and
The annular slot of the ultrafiltration film layer.
The ultrafiltration film layer is hollow tubular structures or solid tubular structure.
After said structure, a kind of modified composite filter element of the utility model, to be illustrated by filter medium as water, first pass through
Harmful organic matter, peculiar smell, chlorine residue, silt, iron rust etc. in charcoal earthenware film layer absorption water, then pass through ion-exchange fibre film layer
The harmful substances such as heavy metal, chlorine residue in removing water, solve secondary pollution finally by ultrafiltration film layer, reach high efficiency filter and drink
The purpose of water, ensure water safety.
A kind of modified composite filter element of the utility model has the advantages that:Because filter element body includes charcoal earthenware
Film layer, ion-exchange fibre film layer and ultrafiltration film layer, the work principle of filter of each layer filter membranous layer corresponds to respectively to be belonged to absorption filtering material, hands over
Filter material is changed, exchange filter material and intercepts the combination of filter material, and adjacent two kinds of filter materials are xenogenesis filter material;During filtering, by filter medium according to
It is secondary to be filtered through the filter material with different work principle of filter, under the conditions of comparable size, specification, filter efficacy can be significantly improved,
Realize a variety of filter efficacies;That is, on the premise of equal filter efficacy is realized, the profile chi of filter core can be substantially reduced
Very little, saving filter material.
A kind of modified composite filter element of the utility model, can be applicable in tap or water purifier or filtering cup, protect
Hinder safe drinking water.A kind of modified composite filter element of the utility model, each filter membranous layer assembling is simple and convenient, and filter effect is effective and pacifies
Entirely.

Embodiment
In order to which the technical solution of the utility model is explained further, the utility model is entered below by specific embodiment
Row elaborates.
A kind of modified composite filter element, as Figure 1-Figure 2, including filter element body and the filter for installing filter element body
Lid 1, filter element body include charcoal earthenware film layer 2, ion-exchange fibre film layer 3 and the ultrafiltration film layer that ecto-entad is set gradually
4.It is separately provided for installing the annular of charcoal earthenware film layer 2, ion-exchange fibre film layer 3 and ultrafiltration film layer 4 in filter cover 1
Neck, each periosteum layer are arranged in filter cover 1 by corresponding annular slot.The section of charcoal earthenware film layer 2 takes the shape of the letter U periosteum knot
Structure, the shape of filter cover 1 are adapted with the outline of the upper end of charcoal earthenware film layer 2 so that the upper end of charcoal earthenware film layer 2 and filter
The week of lid 1, the madial wall of ion-exchange fibre film layer 3 and charcoal earthenware film layer 2 was brought into close contact, ultrafiltration film layer 4 along being tightly connected
For hollow tubular structures or solid tubular structure.
Liquid outlet 11 is provided with filter cover 1, liquid outlet 11 is hickey, facilitates the installation of the modified composite filter element,
