Abstract
The water-purifying filter film is constituted by painting chitin layer onto the base layer and is used to reach the aim of filtering out the impurity from water and purifying water. The present invention has the advantages of simple structure, low cost and good filtering effect.
Description
Technical field:
The present invention is about a kind of water-purifying filter film, particularly a kind of water-purifying filter film that adopts the macromolecule chitin as filter structure.
Background technology:
Whether the cleaning of drinking water, concerns the healthy of drinking person, can't neglect really.For general family, running water, underground water, well water are the main sources of drinking water, cook, boil tea such as, endure boiling hotly etc., all need use a large amount of drinking water.The most traditional drinking water treatment mode, be by bacterium or microorganism in the high temperature heat-killed water, yet, along with environmental pollution severe exacerbation day by day and the rolling up of pollution sources, cause containing in the former water (as: running water, underground water, well water) harmful substance of influential health, relatively significantly increase; Therefore, even former water is boiled processing, still the harmful substance in the former water can't be got rid of.
Have water treatment mode only by filtering, could be really with the in addition filtering of the impurity that contained in the former water, harmful substance.Traditional water filtration processing mode has multiple, have by filter pulp filtration person, active carbon filtration person or the like, yet the effect of its filtration is quite limited, only can with in the water than the impurity filtering of coarse particales, for the thinner impurity of molecule kenel, effectively filtering.Therefore, in the known filter plant,, then can add and join reverse osmosis filtration device, carry out filtration treatment completely if will obtain real pure drinking water.It should be noted that the involving great expense of reverse osmosis filtration device, aquifer yield is low and can expend flushing water, for for the user of big yield demand, and uneconomical; On the other hand, the filter effect of the fore filter of reverse osmosis filtration device (as the filter pulp filter) is good more, then can prolong the service life of reverse osmosis filter membrane (abbreviation RO film).
Summary of the invention:
The technical problem to be solved in the present invention is the deficiency that overcomes present prior art, and a kind of water-purifying filter film is provided, and that this film should have is simple in structure, good filtration effect, characteristics that cost is low, and meets user's actual demand.
Technical solution of the present invention is evenly to be coated with macromolecule chitin layer in basic unit's appearance to constitute, and this chitin layer can be coated on the outside two-sided of basic unit.
This basic unit can be metal or nonmetal or plastics.
This basic unit can be nonwoven.
This basic unit can be chemical fabric.
This basic unit can be paper.
The water-purifying filter film that this basic unit and chitin layer are constituted can be wound on the filter frame, and the inner space of filter frame is separated with the external world mutually by water-purifying filter film.
A kind of water-purifying filter film of the present invention, mainly be to constitute at basic unit's high molecular chitin layer of outside evenly coating, hinder impurity in the former water by the chitin metafiltration, and reach the purpose of water purification, therefore, structure of the present invention is simplified, and has broken through in the past the bottleneck that must can filtering segment sub-impurity by accurate complex apparatus; Moreover, because the price of chitin is quite cheap, thus the present invention have with low cost, structure is simplified, the advantage of good filtration effect.

Fig. 4 is the present invention and filter frame mated condition cutaway view.
Among the figure: the 20-of 10-basic unit chitin layer 30-filter frame 31-inner space
The specific embodiment:
Fig. 1, Fig. 2 and Fig. 3 are the structure chart of a kind of water-purifying filter film embodiment of the present invention, and it mainly is in 20 formation of a basic unit 10 outside evenly coating chitin layers, wherein:
This basic unit 10 has the water flowing characteristic, can be various cloth or paper and constitutes, and for example: nonwoven, chemical fabric etc. all can be used as the basic structure of water-purifying filter film and forms;
This chitin layer 20 is a polymer substance, can be coated on the outside of basic unit 10 equably, for example: chitin can be coated uniformly the outside single or double (as Fig. 2, shown in Figure 3) of basic unit 10, can be constituted water-purifying filter film of the present invention; This water purification filter has the good water general character that the molecule that can supply water passes through, and for impurity or greater than the harmful substance of hydrone, then has the effect of filtration resistance, to reach the water filtration processing operation;
What deserves to be explained is, chitin layer 20 of the present invention, it mainly is to have CHITOSAN (rescue many kind) to constitute, and (CHITOSAN) is that formal name used at school is the mixture of chitin, spherical chitosan; In fact, CHITOSAN (rescuing how kind) is the polymer substance that forms with shrimp, crab shell institute refining refinement, is referred to as " chitin " again; Additional disclosure be, chitin has the general character of food fiber, and have the water conservation swelling, diffusion suppresses and very strong adsorptivity.
When the present invention uses, water-purifying filter film can be wound on (as shown in Figure 4) on the filter frame 30, filter frame 30 inner spaces 31 are separated with the external world mutually by water-purifying filter film, when current pass through water-purifying filter film, impurity in the water can be by the filter that macromolecule hinders of chitin layer 20, hydrone is then smooth and easy by chitin layer 20 and basic unit 10, can reach the purpose of water purification effectively with the impurity filtering in the water in view of the above.
What deserves to be mentioned is, for the water filter industrial circle, as adopt the present invention to adopt chitin as filter structure, be brand-new field and implement go up structure and quite simplify, broken through in the past the bottleneck that must can filtering segment sub-impurity by accurate complex apparatus (as: reverse osmosis equipment for filtering water); Moreover, because the price of chitin is quite cheap, actual needs such as therefore for industrial circle and user, that the present invention meets is with low cost, structure is simplified.
On the other hand, since of the present invention with low cost and filter effect is excellent, therefore,, the most impurity filterings in the former water can be able to be prolonged the service life of reverse osmosis filter membrane applicable to the preposition filtration of reverse osmosis filtration.
In sum, the disclosed structure of the embodiment of the invention because operation when implementing, mainly is to constitute at basic unit's outside coating macromolecule chitin layer, hinders the purpose that impurity in the former water reaches water purification by the chitin metafiltration.The present invention sees through water-purifying filter film that chitin constituted and implements to go up structure and simplify, and broken through in the past the bottleneck that must can filtering segment sub-impurity by accurate complex apparatus; Because the price of chitin is quite cheap, so for industrial circle and user, with low cost, advantages such as structure is simplified, good filtration effect that the present invention has.Propose the application of patent of invention in accordance with the law, please give and examine also patent early.
