Abstract

A water purifier includes a water inlet, a water outlet and a filter layer, wherein the filter layer includes a coarse filter layer, a carbon filter layer and a membrane filer layer from top to bottom, the coarse filter layer is provided with a perforated plate and filtration fiber, the carbon filter layer is provided with activated carbon, a perforated plate and micro-porous filtration fiber, the membrane filer layer is provided with an ultra-fine filter membrane, the filtration fiber is made of non-woven fabric and is multi-layered, the carbon filter layer includes granular powered activated carbon, and the size of membrane holes of the ultra-fine filter membrane ranges from 1.2nm to 3.2nm. The coarse filter layer is used for removing solid foreign materials and iron rust from tap water, and the membrane filer layer is used for removing residual granular solids, suspended foreign materials and bacteria (Escherichia coli). The water purifier which is simple in structure can be directly used on water taps conveniently.

Description

Water purifier

One, technical field

The utility model relates to water correction plant, particularly relates to water purifier.

Two, background technology

Progress along with science and technology, people improve constantly the standard and the quality of productive life, high-quality water demand is increased fast, yet, water pollutes and water resources lacks and becomes restriction, and generally contain solid sundries in the existing tap water, the objectionable impuritiess such as haloform of iron rust, chlorine disinfectant generation, soluble lead, chlorinated lime flavor etc.These objectionable impuritiess are also threatening people's physical and mental health.Removing these objectionable impuritiess will be, on the existing resources basis, and the practical measures of advancing in living standard.

At present, water purifier adopts different types of purification system according to filtration types, and generally the purification system with filtering membrane is the most effective, because it can remove the impurity that comprises such as small materials such as bacterium and heavy metals.

Filtering membrane has a kind of ultra-filtration membrane, reverse osmosis membrane and nanofiltration membrane, and wherein, ultra-filtration membrane is mainly used in the material of removing the colloid size, can't remove the small material as bacterium and heavy metal.Reverse osmosis membrane can remove and degerms and small material such as heavy metal, thereby widespread use, but stores the water purifying storage tank because of this water cleaning systems is provided with, and has increased the volume of water purifier, and the storage time prolongs and makes microbial reproduction and cause secondary pollution.Nanofiltration membrane water purifier Chinese patent 03145434.8 (need not the nanofiltration membrane base household water filter of storage tank), the nanofiltration membrane of a kind of its micropore size at 0.1-10nm disclosed, its water cleaning systems is by pressure pump, pretreatment filters, pre-treatment carbon filter and nanofiltration membrane strainer and posttreatment filter, regulate the input rate and the working pressure of not purifying waste water by pressure pump, could work in 1-12 liter/minute scope at pressure 15-120 pound/square inch, flow, like this to not using under the situation of non-transformer and low discharge.

Three, summary of the invention

The purpose of this utility model is in order to overcome above-mentioned weak point, to provide a kind of simple in structure, can be used for low discharge, the water purifier that uses under the general tap water pressure situation.

In order to reach described purpose, a kind of water purifier comprises water-in, water outlet and filtering layer, filtering layer comprises coarse filtration layer, charcoal layer filtering layer and membrane filtration layer, and from top to bottom, the coarse filtration layer has porous plate and filter fiber between the layer, charcoal layer filtering layer has gac, porous plate and millipore filtration fiber, the membrane filtration layer has ultra-fine filter membrane, and filter fiber is that non-woven fabrics is made, and is multilayer, charcoal layer filtering layer is small-particle powdered gac, and ultra-fine filter membrane fenestra size is at 1.2-3.2nm.

The beneficial effects of the utility model are to divide three layers of purification, solid sundries, iron rust in the coarse filtration layer removal tap water; Charcoal layer filtering layer remove objectionable impuritiess such as haloform that the tap water chlorine disinfectant produces, be dissolved in peculiar smell such as lead in the tap water and chlorinated lime; The membrane filtration layer is removed remaining fine-particle solid, suspending sundries, bacterium class (intestinal bacteria etc.).It is simple in structure, can directly be connected on the water tap to use, and is convenient.

Five, embodiment

Specific embodiment of the utility model: water purifier comprises water-in, water outlet and filtering layer, filtering layer comprises the coarse filtration layer, charcoal layer filtering layer and membrane filtration layer, filtering layer respectively from top to bottom, water purifier is suitable for reading the rubber coating 1 that matches with water tap water outlet size, link to each other with shell by gland 2, tap water carries out coarse filtration by porous plate 6 and filter fiber 3, filter fiber is made by the multi-layer nonwoven fabrics material, with the solid sundries in the tap water, iron rust is removed, form charcoal layer filtering layer by small-particle powdered gac 4 and millipore filtration fiber 5, remove the objectionable impuritiess such as haloform that the tap water chlorine disinfectant produces, be dissolved in peculiar smell such as lead in the tap water and chlorinated lime, the membrane filtration layer of forming at the ultra-fine filter membrane 7 of 1.2-3.2nm by the fenestra size, remaining fine-particle solid will be removed, suspending sundries, bacterium class (intestinal bacteria etc.) will flow out from water outlet 8 through the tap water behind the three layer filtration.
