Description

Purifier for running water complex filter element production technology
Technical field
The invention belongs to infant industry field of material technology, more particularly to a kind of purifier for running water complex filter element production Technique.
Background technology
Originally hydraulic art generally comprises three steps；Coagulation, addition aluminium chloride, aluminum sulfate or ferric trichloride in raw water The materials such as suspension, colloid are made to generate easy precipitated crystal.Subsequently into sedimentation basin, after the precipitation regular hour, outflow is passed through The reprint filtering (or siphon filtering) of quartz sand composition, is eventually adding chlorine liquid and carries out disinfection processing.
Originally water pollution：Water treatment technique is all the primary filter carried out to even up to ten thousand tons water of hundreds of tons, because Series is excessively huge, it is difficult to ensure that filter effect.The addition of chlorine liquid, although restraining and sterilizing bacteria, actually also into major hidden danger, chlorine The chloroform that gas is produced is acknowledged as strong carcinogen；Even if clean running water, pass through also face after several kilometers of pipelines Mesh is entirely non-, here it is well-known running water secondary pollution.Including galvanized pipe pollution, water pipe, tap get rusty, high building water tank rubbish Rubbish pollutes, and these all turn into the hidden danger of running water.
Running water has all been used in existing rural area substantially simultaneously, and this is also the huge achievement of China's new countryside construction.According to relevant Department statistics, the popularity rate of cities and towns purifier for running water has reached more than 65%, and also has the trend being gradually increasing, with That quality of the life is required to improve and water pollution problems is highlighted, the health and environmental consciousness of consumer is more and more ripe, running water Filtering is just arisen at the historic moment.
Purifier for running water is superfine fibre melt blown filter core with filtration core majority in the market, and traditional running water surpasses Fine fibre melt blown filter core, filtration mechanism is to rely on the countless traps formed between fiber and the substantial amounts of specific surface area of fiber, right Originally water impurity is by the comprehensive functions such as inertia, friction, collision, absorption and capture, and existing running water superfine fibre was meltblown Filter core has the disadvantage that filtration resistance is big, filter efficiency is low, it is big to cause clarifier to run noise.Various bacteriums are easily in filtration core in water Internal and surface colonization, forms secondary pollution, destroys water quality, health is caused to have a strong impact on.
Therefore being needed badly among prior art wants a kind of new technical scheme to solve this problem.
The content of the invention
The technical problems to be solved by the invention are：A kind of purifier for running water complex filter element production technology is provided, adopted It is processed into electrostatic fibre Nonwovens filter medium and electret melt-blowing nonwoven electrostatic filter media MULTILAYER COMPOSITE Purifier for running water complex filter element with plural layer, this NEW TYPE OF COMPOSITE filtration core and traditional superfine fibre melt blown filter Core compares, filtration resistance is small, filter efficiency is high, consuming little energy, operation noise it is low.
To reach above-mentioned purpose, the present invention proposes a kind of purifier for running water complex filter element production technology, it is characterized in that： Comprise the following steps,
Step 1: making electrostatic fibre Nonwovens filter medium
1. fiber opens bag mixing
It is raw material to take with electrostatic polypropene staple, and fiber carries out thick shredding by opener pinion roller, slightly Fiber after shredding carries out smart shredding by serration roller, obtains the loose fiber that electrostatic field reduces；Loose fiber passes through conveying Pipeline is entered in big storehouse cotton blender machine, carries out fiber mixing；
2. comb
The quantitative cotton feeder of air pressure is transported to through air-flow by the step is 1. middle, mix through the big well-mixed fiber of storehouse cotton blender machine Condensating fiber is transported to carding machine by pressure, in carding process, adds electrical static eliminator, combs to formation single layer fibre net, And web is sent into the wild crops being made up of three pairs of rollers by doffer and pattern doffing roller, tend to web vertical transverse strength Unanimously；
3. the web 2. step obtained is fed into the adhesion area of hot-rolling mill by defeated lace curtaining, carries out hot rolling and glues Conjunction is handled, and hot-rolled temperature is 115 DEG C~165 DEG C, and pressure is 2.5 × 103N/cm~7.5 × 103N/cm, web is melt bonded Afterwards, room temperature is naturally cooled to, electrostatic fibre Nonwovens filter medium is obtained；
Step 2: making melt-blowing nonwoven filter medium
It is raw material to take polypropylene chip, carries out drying and processing, drying to water content 0.3%, by by drying and processing Polypropylene chip is fed into screw extruder, and heating is melt into polyacrylic polymer, and polyacrylic polymer is through measuring pump-metered Sprayed afterwards by shower nozzle, solidify to form fiber through air-flow stretching and agglomerate on web forming device, obtain melt-blowing nonwoven filtering Jie Matter, the fibre fineness of melt-blowing nonwoven filter medium is 0.055dtex~1.110dtex；
Step 3: the melt-blowing nonwoven filter medium that the step 2 is obtained applies electricity through electret electrostatic equipment Pressure, application voltage is 1KV~10KV, carries out staying polarization process, obtains electret melt-blowing nonwoven electrostatic filter media, will stay The melt-blowing nonwoven electrostatic filter media that polarizes and the electrostatic fibre Nonwovens filter medium that the step one is obtained are same When be fed into compounding machine, form the composite filter media with double-decker；
Step 4: according to purifier for running water specification requirement, there is the compound of double-decker by what the step 3 was obtained Filter medium is cut through coiling cutting machine, is machined to the purifier for running water combined filtration with plural layer after cutting through paper folding Core.
By above-mentioned design, the present invention can bring following beneficial effect：
The present invention is to utilize electrostatic fibre Nonwovens filter medium and electret melt-blowing nonwoven electro static filtering It is dielectric multi-layered compound, it is processed into Novel tap water clarifier complex filter element.Use first with electrostatic polypropene staple for Raw material, will be processed into electrostatic fibre hot rolling non-woven using Nonwovens production technology with electrostatic polypropene staple Cloth filter medium, then again with electret melt-blowing nonwoven electrostatic filter media MULTILAYER COMPOSITE, Novel filtering core is made.It is this Novel filtering core compared with traditional superfine fibre melt blown filter core, filtration resistance is small, filter efficiency is high, consuming little energy, Run noise low.
Because the present invention is in addition to using countless fiber traps in filter medium, the filtering of electrostatic fibre Nonwovens is situated between Matter and electret melt-blowing nonwoven electrostatic filter media in itself all have stronger electrostatic field and electrostatic charge, electrostatic charge and The collective effect of electrostatic field Coulomb force, is greatly increased to impurities in water and various bacteriums, bacillus and other noxious pollutants Filter effect, considerably beyond superfine fibre melt blown filter core.Meanwhile, its internal or table can not be regularly replaced by also solving filtration core The problem of face bacterial reproduction, because electrostatic fibre electric charge can effectively suppress bacterial reproduction with electrostatic field, effectively it can kill in water Various bacteriums, bacillus and other noxious pollutants, the purifier for running water complex filter element production technology production that the present invention is provided Go out purifier for running water complex filter element to ensure that people's drinking public water supply provides safe and reliable technical guarantee, application market Development space is very big, and economic benefit and social benefit are very notable.
