Description
Technical field
The present invention relates to tap water purifying technical field, be specially a kind of membrane filtration water tap and the using method thereof with sturdy and durable, long-acting bactericidal feature.
Background technology
Along with the raising day by day of people's living standard, and the increasingly sharpening of environmental pollution, people more and more pay close attention to drinking water safety, especially terminal water purification from the beginning, by increasing filters at water outlet, ensure the safety of household drinking water and domestic water.
Tap water is by pipeline and pressurizing device, and through very long pipeline and complicated landform, flow into huge numbers of families from water factory, some pipeline is long neglected and in disrepair, and some pipeline intersects with waste pipe, exist various in ooze problem, cause the larger hidden danger of running water safety existence; In addition because historical problem causes water supply network construction material hygienic standard to differ, the substandard cast iron pipe of a large amount of existence, cement pipe and plastics tubing, have various corrosion and heavy metal leakage problem, these situations all cause safely great hidden danger and risk to domestic water.
Because faucet water purifier can better solve above risk, be commercially widely used, faucet water purifier, because of its small and exquisite outward appearance, improves the effect that water quality is got instant result, the succinct facility of installation and maintenance, the dark welcome by market.
Current faucet water purifier on the market is mainly arranged on the outlet of water tap, and volume is comparatively large, is difficult to compatible with water tap moulding, can not forms total tune effect attractive in appearance; Existing faucet water purifier is mainly filer element type in addition, and filtration area is little, filtration resistance is large, and aquifer yield is little, is difficult to the requirement reaching the specified aquifer yield of water tap; Faucet water purifier filter core is short for work-ing life, is difficult to thorough regeneration, and need periodic replacement, use cost is relatively high, is not inconsistent with the family lifestyle of green, low-carbon (LC), environmental protection development trend; Existing faucet water purifier lacks long-acting bactericidal means, and the easy cooperating microorganisms of the impurity be trapped, produces fearful secondary pollution.
Summary of the invention
For above problem, the object of this invention is to provide a kind of have overall appearance, aquifer yield large, sturdy and durable, can holomorphosis, long-acting bactericidal advantage membrane filtration water tap.
The present invention is directed to the inharmonic problem of faucet water purifier outward appearance, the one body swimming tap providing a kind of filtering unit to be arranged on water tap inside, filtering unit is the occupying volume external space not, unified with water tap moulding, does not affect water tap aesthetics design effect.
Another problem that the present invention will solve is: the feature little for existing faucet water purifier filter element filtering area, aquifer yield is little, provides a kind of applying unit volume effective filtration area is large, filter wall is thin ceramic honey comb film as the membrane filtration water tap of filter material.Ceramic honey comb film has the feature of hyperchannel and thin-walled, and number of channels is between 50-800 order, and unit volume filtration area can reach 0.2-5m
2/ L, filtration area is several times to tens times of conventional single-channel filter core; Ceramic honey comb membranous wall is thick in 0.1-1mm, thinner than conventional filter core, can realize larger permeable amount.
Another problem that the present invention will solve is: for the situation that faucet water purifier filter element life is short, there is provided a kind of ceramic honey comb film and stainless steel membrane (net) of using as the membrane filtration water tap of core filtering material, and the method for cleaning and regeneration and chemical regeneration.Ceramic honey comb membrane material comprises one or more in aluminum oxide, zirconium white, titanium oxide, silicon oxide, silicon carbide, trichroite, clay, stainless steel membrane (net) adopts 316L material, all realize regeneration by ultrasonic wave water washing and soda acid matting, there is the work-ing life of overlength.
Another problem that the present invention will solve is: for the problem of the easy cooperating microorganisms of conventional faucet strainer, provides a kind of strainer water tap using built-in silver powder, by the wide effect sterilization of silver powder and the innocuousness to human body, ensures the long-term security of tap water.
For solving the technical problem of existing water tap cleaner, technical solution of the present invention is as follows:
A kind of membrane filtration water tap, comprises screwed fitting, filtering unit, water tap; It is characterized in that: described screwed fitting one end is water-in, and one end is connected with filtering unit in addition, the water inlet of described filtering unit other one end connecting tap; Described filtering unit comprises ceramic honey comb film, membrane module shell, and described ceramic honey comb film is arranged in package shell; Described ceramic honey comb film profile is square or circular, and filtration channel cross section is square or square after rounding or chamfering, and the channel cross-section length of side is 0.1-10mm, and channel cross-section wall thickness is 0.1-1mm, and filtration channel length is 10-500mm; Filtration channel is for replacing plug-hole structure; Membrane filtration precision is 0.01-10 micron, and rete filtration symmetrically or unsymmetric structure.
Membrane filtration water tap is used in the method for terminal tap water purifying, it is characterized in that: described method comprises the steps:
(1) tap water purifying
The screwed fitting of water tap flexible pipe with membrane filtration water tap is connected, after water flowing, utilizes tap water pipe network pressure, and membrane filtration water tap top regulating handle can realize filtering and water outlet.First tap water is purified by ceramic honey comb film, then contact with silver powder in ceramic honey comb film cavity, silver powder is filtered and interception by membrane module housing outlet place stainless steel membrane (net), prevents silver powder to run off, and the tap water after final filtration purification flows out at tap outlet place.
(2) cleaning and regeneration process
When life-time service caudacoria filtered water tap water outlet amount drops to and can not meet the demands, carry out cleaning and regeneration.First closed tap water inlet valve, again by the screwed fitting of membrane filtration water tap and the first sealing-ring pressing plate, and second sealing-ring pressing plate and water tap two place take apart, by filtering unit clear water counterflush 2-3 time, then filtering unit entirety is put into Ultrasonic Cleaners cleaning 1-60 minute, period maintenance changes water, till water is limpid water in Ultrasonic Cleaners.
(3) filtering unit and sealing-ring are reinstalled, complete cleaning and regeneration process.
Also further process can be done after step (2), adopt potent chemical regeneration process: process and cleaning and regeneration process difference are after filtering unit ultrasonic wave clear water is washed, first adopt ultrasonic wave alkali lye and clorox mixing solutions ultrasonic cleaning, scavenging period 1-30min; After clear water washing 2-4 time, then adopt ultrasonic wave acid solution to clean, scavenging period 1-30min, after clear water washs 2-4 time, complete chemical regeneration process.
