Description
Technical field
The utility model relates to a kind of water purifier, especially a kind of drink water purifier.
Background technology
Along with the pursuit of people's quality of the life, the quality of domestic water more and more is subject to people's attention.The quality that improves water now all is the mode by purifying.The water purification style of people's employing at present mainly contains active carbon filtration, ultrafiltration membrance filter, and the modes such as several combinations of above-mentioned dual mode.Because activated carbon has adsorption, can remove peculiar smell and partial organic substances in anhydrating, and bigger impurity such as particulate matter, therefore purify waste water and extensively utilized by people with activated carbon.But only with the water after the activated carbon treatment, its quality can't satisfy people's requirements at the higher level.Along with development of science and technology, people begin to adopt ultra-filtration membrane that water is handled, but the bacterium in the ultra-filtration membrane filtered water, mud and partial organic substances.But adopt single ultra-filtration membrane to purify waste water, chlorine residue in the water and heavy metal can not be removed effectively, and water quality does not reach direct drinking standard, and the quality of water still can not reach people's requirement.So people handle these two kinds of processing mode series connection backs to water.This processing mode is greatly improved the quality of water.As China Patent No. 200320118259.3 are called a kind of household water filter that uses multi-stage filter core, and it adopts active carbon filtration and ultrafiltration membrance filter series connection afterwards water to be handled exactly.The processing mode that these two kinds for the treatment of water methods combine makes the quality of water reach people's requirement, it is not compact that but its shortcoming is a structure, simultaneously since activated carbon in use, being easy to absorption reaches capacity, ultra-filtration membrane is easy to produce dirty stifled, as can not counterflush, needs periodic replacement activated carbon and ultra-filtration membrane, cause the use cost height, be difficult to apply.
Summary of the invention
The purpose of this utility model just provides a kind of compact construction, energy counterflush, good purification, a kind of water purifier that use cost is low.
By a kind of water purifier that the utility model proposes, it comprises tubular shell, upper end cover, lower end cover, active carbon filtration layer and ultrafiltration membrance filter layer, the two ends of shell and upper and lower end cap fitted seal, be provided with water-in and water purification mouth on upper end cover, also be provided with water outlet on upper end cover, the shell internal fixing has the film mounting pipe to make shell be divided into inner chamber and exocoel, inside and outside chamber is connected in the bottom, activated carbon is housed in the exocoel, constitutes the active carbon filtration layer, the exocoel upper end is connected with water-in; The inner chamber internal fixing has ultra-filtration membrane, constitutes the ultrafiltration membrance filter layer, and the upper water-out mouth of the film header at ultra-filtration membrane center is connected with the water purification mouth, the sealing of film header lower end, and the side of ultra-filtration membrane upper end is connected with the water outlet of upper end cover.
Adopt technique scheme, during use, running water pipe directly is connected with the water-in of upper end cover, tap water flows into from water-in, to at first pass through the active carbon filtration layer, activated carbon is to the peculiar smell in the water and part is organic and bigger impurity such as particulate matter adsorb, after water passes through the active carbon filtration layer, flow into the ultrafiltration membrance filter layer, bacterium in the water, impurity such as mud and part organic matter will be filtered, water is divided into two parts after coming out from ultra-filtration membrane, and a part flows out through the water purification mouth from the pipe core upper end, become tap water, another part flows out through water outlet from the upper side of ultra-filtration membrane, and the effusive water of water-quality ratio water purification mouth is slightly poor, can be used as the non-domestic water of drinking.Because the upside water of ultra-filtration membrane can flow out by the outlet of upper end cover, so ultra-filtration membrane produces concentration polarization water and discharge from water outlet, so prolongs the work-ing life of ultra-filtration membrane greatly in the water purifying process.
Can realize counterflush for making activated carbon layer of the present utility model, on described end cap, also be provided with the back flushing mouth, be provided with backwash tube in the exocoel, the backwash tube upper end is connected with the recoil mouth of upper end cover, and the lower end is connected with reversing valve all being connected with exocoel and inner chamber on described upper end cover, when being implemented in back flushing, water flows into from the back flushing mouth, and water outlet is closed, and water flows out from water inlet pipe behind the active carbon filtration layer.So in use for some time, close the water purification mouth, start reversing valve, reversing valve cuts out water outlet, and tap water flows into from reversing valve from the back flushing mouth, flow into the active carbon filtration layer from the bottom of backwash tube, to the activated carbon counterflush, the activated carbon that is pressed together gradually by current in the filtration procedure will unclamp gradually like this, will swim in the water attached to the adsorptive on the activated carbon, and flow out through the outlet of reversing valve from water-in downstream, thereby reach the effect of cleaning active charcoal.
In sum,, make shell be divided into inside and outside chamber, in interior exocoel, be made as activated carbon layer and ultrafiltration rete respectively because the utility model adopts coaxial package film mounting pipe on shell, because two-layer coaxial package, so compact construction; Simultaneously because the utility model is provided with reversing valve on end cap, activated carbon layer can oppositely be cleaned, therefore do not need often to change activated carbon, simultaneously when using the effusive water of water out, can just wash ultra-filtration membrane, it is stifled to the dirt of ultra-filtration membrane to reduce concentration polarization, makes the duration of service of ultra-filtration membrane longer, thereby reaches the low advantage of use cost.
