Two, background technology
Drinking water treatment purifier in the family is used increasingly extensive abroad, its major reason is that the public improves constantly the attention degree of water hygiene safety, also applying at Drinking Water in China treatment and purification device at present, wherein modal domestic appliance for treating drinking water is a kind of active carbon filter, its core is the intensive activated carbon granule that is filled in the filter housings, untreated water is flowed into by the inlet of filter, when water during by closely knit activated carbon granule, filter and the double action of absorption under make particle in the water and organic impurities by filtering.Other drinking water filter is also similar with it, but these device for purifying potable water all can only be handled impurity and organic matter in the water, when the water source by large tracts of land chemical pollutant such as pollutions such as benzene or heavy metal ion such as mercury, the effective harmful substance in the filtered water of these devices then.At this moment, the government in contaminated area can only start the calamity emergency prediction scheme, stops water factory's water supply and changes by the supply of uncontamination zone allotment domestic water.This has not only influenced people's order of living normally, and the hysteresis quality and the limitation of allotment water promptly can cause the locality water shortage to occur in a short time.In addition, also similar situation can appear period in wartime and natural calamity.The solution that how to adopt a kind of low cost, family oriented also can in time, effectively solve above-mentioned contradiction is the problem that people's livelihood department should consider.
Three, summary of the invention
Technical problem to be solved in the utility model is different according to the concrete pollutant kind at water source and pollution level, a kind of drink water purifying filter that can effectively filter multiple noxious material is provided, its compact conformation, high efficiency, can long term storage, adopt the modular combination form, use simple, be convenient in the accident emergency processing to drinking water, cost is low and can spread to family and other environment for use.
For achieving the above object, drink water purifying filter described in the utility model comprises joint, modular filtration unit, three major parts of delivery port, and described joint links to each other with water inlet, and the modular filtration units in series links to each other, and the bottom is provided with delivery port.Different filtering modules is filled different filtering materials, therefore can handle different pollutants.
Owing to adopt the modular filtration unit, so change and to make up corresponding filter element very convenient, different filter elements can effectively filter different pollution sources, as adopt activated carbon can filter in the organic matter of small-molecular weight, molecular sieve is fit to remove little molecule, KDF is fit to remove heavy metal ion, and filter membrane is fit to remove particle and macromolecule contaminant etc.
The modular filtration unit comprises external screw thread that links to each other with a last module and the internal thread that links to each other with next module.The upper and lower opening place of filter element is coated with screen pack respectively, and filter medium is filled in the housing.
As required, the utility model can also be provided with shell, water quality detection device and/or service life display module, each filter element is installed in the shell, the water quality detection device and service life display module sensor be located in the water channel, each sensor is connected with display screen on placing shell.
When the supply of city tap-water meets general standard for drinking, then only need to adopt a spot of and filtering module cheaply, for example combination of active carbon filtration unit and filter membrane is used for common particle of filtering and organic matter etc. and gets final product.Can improve the rate of filtration like this and reduce the invalid loss of other filter medium; In case and urban water resource is when being polluted by organic pollutant benzene or heavy metal such as mercury ion etc., the quantity that then can change filter element at once or add filter element, like this can be in the poisonous and harmful substance in the least significant end degree of depth removing water of water-supply systems, reach standard for drinking, thereby conserve water processing cost, guarantee that life is stable, the stagnation fully of avoiding urban drinking water to supply with.And if the waterworks sets up filter and will reach corresponding standard, technically also can realize.But equipment is installed, the cycle of debugging is long, invest excessive, and because the running water 70-80% that comes out of water factory is used for the non-purpose (as bathing, wash clothes, flush the toilet in the toilet etc.) of drinking, it is unnecessary that this part water is carried out advanced treating, also is uneconomic simultaneously.And the utility model only need be installed on the tap of drinking water in the kitchen in family uses, and delivery ports such as other parts such as water closet need not to use, thus can be effective, economical address this problem.In addition, the utility model also can be applied in many aspects such as potable water supply of dining room, hotel, station, train, field work and field army.
