Abstract
The present invention relates to a portable nanofiltration water purification cup. The cup comprises a cup body, a cup lid and an internal detachable water purification structure. The cup consists of four layers, namely a raw water storage layer 5, an active carbon adsorbing impurity layer 6, a hollow fiber nanofiltration layer 7 and a purified water storage layer 8. A water outlet 9 is formed in the side part of the cup body, a small manual pump 1, pressurizing the water storage layer to improve the filtration velocity, is connected on the cup lid through a screw and a pipe, and the cup lid is provided with a sealing ring to ensure the good air-tightness of the water storage layer and the filtration layer during pressurization. The cup is arranged in a compact portable structure, and field water such as river water, lake water and brackish water can be filtered into direct drinking water, so that the cup is good in practicality, simple in structure, easy to operate, convenient to carry, free of electrical energy, energy-saving, environmental-friendly, delicate and attractive.
Description
Technical field
The present invention relates to a portable nanofiltration water purifying cup, belong to drinking water apparatus field.Be specially and adopt gac and hollow-fibre membrane to retain the field water such as art breading river, well water, brackish water combined, for field play, investigation personnel and operation soldier etc. provide and directly can draw drinking-water, greatly alleviate the burden that people carry tap water.
Background technology
People travel in the wild, explore, army fights in the wild, all need water capable of direct drinking, and rivers, lake, most of undressed surface water all contains various bacteria, virus, poisonous and harmful organic pollutant etc. in pond etc., and the surface water after the serious disasters and accidents such as earthquake, rubble flow particularly occurs.Drink these sordid water and can cause various diseases, as escherichia coli gastroenteritis, diarrhoea, urinary system infection, Salmonellas property typhoid fever, bacillary dysentery etc., long-term drinking also can cause various lithiasis, cardiovascular and cerebrovascular diseases, therefore Drinking Water Problem becomes a large problem of outdoor life, water purifying cup just can purify waste water to ensure safe drinking water out of doors whenever and wherever possible, greatly alleviates the burden that people carry tap water.But all there is some deficiency in existing Portable water purification glass, as coiled reverse osmosis membrane water purifying cup needs pressure larger, must by means of external enwergy, and cleaning comparatively bothers, ultra-filtration membrane water purifying cup can not well remove water hardness, heavy metal ion and small organic molecule etc., require high to former aqueous condition, although some water purifying cup has good treatment effect in addition, there is the problems such as complex structure, production cost is high, operation is inconvenient.
Summary of the invention
The present invention is a kind of portable nanofiltration water purifying cup, and structure is simple, and operate simple and easy, treatment effect is good,
The Drinking Water Problem that field does not have when directly can quote water source can be solved.Water purifying cup comprises cup, bowl cover and inside removably water purification structure, its principal character is that cup is formed by four layers, the first layer is the former water layer of storage, the second layer is charcoal absorption impurity layer, third layer is tubular fibre nanofiltration layer, 4th layer is storage water purification layer, a water outlet is provided with at the sidepiece of cup, bowl cover is provided with safety valve and pressure release valve, and connect a small-sized hand-operated inflator, for storing up the pressurization of former water layer to improve filtration velocity, inflator is connected by screw thread and pipeline with bowl cover, and when bowl cover is added with sealing-ring to ensure to pressurize, resistance to air loss is good.
Know-why of the present invention: adopt manual pump pressurization to make former water successively by gac and hollow fiber nanofiltration membrane, filter and obtain clean water.Gac is as the pre-treatment in water treatment, and major function removes look, taste, organic chloride etc., and reduce the processing load of subsequent technique, gac can also remove the large granular impurity such as silt, iron rust in water.Hollow fiber nanofiltration membrane can natural organic matter and sulfate and nitrate etc. in trap water, can effectively remove water hardness, heavy metal ion, bacterium, virus etc., ensure that the safety of tap water, also trace mineral element can be retained simultaneously, meeting the demand of human body to mineral ion, is the important flow process in mineral water, mountain spring water production technique.This kind of portable nanofiltration water purifying cup practicality be good, easy to carry, without the need to electric energy, energy-conserving and environment-protective, exquisite attractive in appearance.Concrete advantage is as follows:
(1) polysulfones hollow fiber nanofiltration membrane has nano level aperture, and comparatively ultra-filtration membrane, ceramic membrane more can effectively remove the impurity such as water hardness, heavy metal ion, bacterium, virus.
(2) polysulfones hollow fiber nanofiltration membrane has that good film-forming properties, thermostability, chemical stability, physical strength are high, acid and alkali-resistance and microbial attack, chlorine-resistant and other oxidizing substance, has high water flux and high salt rejection (can reach 98%), anticol body and suspended solid pollutant, affordable.
(3) hollow fiber nanofiltration membrane film surface-area is large, and filtration efficiency is high.
(4) without the need to electric energy, required pressure ratio reverse osmosis membrane water purifying cup is little, and manual pump can provide enough pressure, belongs to real low-carbon (LC), environmental protection water purifying plant.
(5) small volume and less weight, safety non-toxic, light weight, non-corrosiveness, on-deformable polycarbonate material that shell uses, about gross weight 400g.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present invention, and in figure, 1 is small-sized hand-operated inflator, and 2 is pressure release valves, and 3 is safety valve, and 4 is bowl covers, and 5 is the former water layers of storage, and 6 is activated carbon adsorption layers, and 7 is tubular fibre nanofiltration layers, and 8 is storage water purification layers, and 9 is water outlets.
Embodiment
Below in conjunction with embodiment and accompanying drawing thereof the present invention program done and illustrate further.Adopt cup type structure, comprise cup 5, bowl cover 4 and inside removably water purification structure, be made up of four-layer structure, the first layer stores up former water layer 5, second layer activated carbon adsorption layer 6, third layer tubular fibre nanofiltration layer 7,4th layer of storage water purification layer 8, bowl cover is provided with safety valve 3 and exhaust pressure relief valve 2, bowl cover is added with sealing-ring and is connected with cup, small-sized hand-operated inflator 1 is connected with bowl cover with pipeline by screw thread, and cup bottom side is provided with a water outlet 9.Add water to during use storage former water layer, twist good bowl cover, connect inflator pressurization make water finally obtain water purification by water outlet 9 by gac and nanofiltration membrane successively.
