CN2362848Y - Water purifier without substituting core - Google Patents

Abstract

The utility model discloses a water purifier without a substituting core, which is characterized in that a fully-sealing structure is adopted; microporous ultrafiltration membrane filter is added On the basis of the original water purifier, and in such a way, not only the water pressure of outlet water is larger, but also the water processed is divided into daily use water and drinking water which are respectively sent out; in a back-flushing device, the utility model can use a porous screen plate to replace a porous tube, and thus, not only the back flushing is uniform, but also the phenomenon that the back-flushing device is easy to be blocked is avoided.

Description

The no need to replace element purifier

The utility model relates to a kind of no need to replace element purifier, in particular for removing the no need to replace element purifier of secondary pollutants such as iron rust, red worm, bacterium in the tap water.

Existing purifier all adopts filter element filtering, and the time one is long, the blocked inefficacy of micropore filter element, and just more renew cartridge can continue to use.Chinese patent ZL95222206.X discloses a kind of family water purifier that need not change core, it utilizes back-flushing method to solve the filtrate blocking problem, it is relatively poor that but this purifier is removed the ability of bacterium, virus, for cause the tap water that bacteria content is more or turbidity is bigger because of secondary pollution, the water quality after the purification can't reach the national health drinking water standard.Because this device adopts Open architecture, makes that water outlet hydraulic pressure is low, uses very inconvenient.And the perforated tube that it adopts in back-purge system is more blocked, causes whole purifier work undesired.

The purpose of this utility model provides a kind ofly can thoroughly remove the especially no need to replace element purifier of bacterium, virus of secondary pollutant in the tap water, and this device also has higher water outlet hydraulic pressure, and back-purge system wherein is difficult for blocked.

Main technical schemes of the present utility model is: this device comprises pressure hose, water intaking valve, water inlet pipe, dual-purpose pipe, the body skin that connects successively; The clear water rising pipe that is connected with body skin, the clear water outlet valve, the back flushing water inlet pipe, the back flushing water intaking valve, and blow-off pipe, wash water valve, the porous web plate, micropore ultra-filtration membrane district, the drinking-water rising pipe of band drinking-water outlet valve, body skin is a sealed structure, in body skin, arrange water distributing area successively, the granule filter material layer, the Maifanitum mineralized layer, the porous web plate, the catchment area, the micropore ultra-filtration membrane district that forms by a large amount of tubulose micropore ultra-filtration membranes, clear water zone, the mouth of pipe of dual-purpose pipe reaches the granule filter material laminar surface, the clear water rising pipe links to each other with clear water zone, the drinking-water rising pipe is connected with micropore ultra-filtration membrane district from the normal direction of micropore ultra-filtration membrane, back flushing water inlet pipe one end is connected with the catchment area, the other end is connected on the water inlet pipe, and the blow-off pipe that has wash water valve links to each other with dual-purpose pipe.

After adopting said structure, the utlity model has following beneficial features, in the scavenging process pressure hose is connected with running water pipe, open water intaking valve, drinking-water outlet valve or clear water outlet valve, close back flushing water intaking valve, wash water valve, the tap water that is subjected to secondary pollution arrives the granule filter material layer through water inlet pipe, dual-purpose pipe, removes larger particles impurity such as red worm, iron rust in the water; The granule filter material laminar surface can form the microbially decontaminate film gradually after work for some time, it can be degraded and remove deliquescent organic impurity, inorganic impurity in the water; Through the filtering water of granule filter material floor by Maifanitum mineralized layer mineralising after the catchment area arrives micropore ultra-filtration membrane district, the micropore ultra-filtration membrane adopts the rectangular cross flow principle, because micropore ultra-filtration membrane membranous wall aperture is less than 0.01 micron, and the bacterium diameter is usually more than 0.5 micron, so the water by micropore ultra-filtration membrane membranous wall contains bacterium hardly through the discharge of drinking-water rising pipe, its water quality is better than domestic and international drinking water standard, the water by the micropore ultra-filtration membrane does not then enter clear water zone through the pipeline that micropore ultra-filtration membrane membranous wall surrounds, draw as domestic water through the clear water rising pipe, can automatically the trapped substance on the ultra-filtration membrane be washed away simultaneously.So just finished scavenging process.Because body skin is a sealed structure, so the water after purifying can also keep higher hydraulic pressure.And after using for some time (an about week), granule filter material layer in the device increases with aging the gathering of microbial film filtration resistance is increased because of being trapped impurity, the device water production rate reduces, carry out back flushing this moment, device is restored one's working ability: close water intaking valve, drinking-water outlet valve, clear water outlet valve, open back flushing water intaking valve and wash water valve, backwashing water through the catchment area oppositely successively to porous web plate, Maifanitum mineralized layer, the granule filter material layer washes, water after the flushing is discharged through dual-purpose pipe, blow-off pipe, finishes backwash process.

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
