Abstract

The utility model relates to a household water clarifier, in particular to a household water clarifier using a multistage filter element. Three end to end filter element cavities are provided on the reality of shell of the water clarifier, the water outlet end of a first class hollow ultrafiltration membrane filter element is connected with the water inlet end of an active carbon filter element. The water outlet end of the active carbon filter element is connected with the water inlet end of a second class hollow ultrafiltration membrane filter element, and the water outlet end of the water clarifier is connected with the water outlet end of the second class hollow ultrafiltration membrane filter element. The utility model solves the problem that the past hollow ultrafiltration membrane water clarifier and active carbon water clarifier cannot completely eliminate baleful matters, germ and gases in purified water.

Description

A kind of household water filter that uses multi-stage filter core

Technical field the utility model relates to a kind of household water filter, refers to use the household water filter of multi-stage filter core especially.

Background technology is well-known, what present family expenses hollow fiber ultrafiltration film water purifier adopted is hollow fiber ultrafiltration membrane cartridge filtering technique, its pore size filter reaches 0.01 micron, harmful organism and the heavy metal of bacterium, colloid, iron rust, red worm, moss, silt and part in the thorough filtering tap water of energy, keep beneficial mineral matter in the water, be a kind of pure physical filtering, the water purification mode of no chemical pollution; Colloid in the filtering water can not form incrustation scale, does not need the energy, utilizes tap water pressure work, energy-conserving and environment-protective, thereby be widely used on family's water treating equipment.But because the restriction of hollow fiber ultrafiltration membrane cartridge self-characteristic can't filter gases such as chlorine residue harmful in the tap water, chloroform, trichloromethane in filtration procedure.There is a kind of active carbon filter core water purifier to utilize the adsorption of gac now, can remove gases such as chlorine residue harmful in the tap water, chloroform, trichloromethane, if because the easy absorption of gac is saturated, saturated back since its can not reuse and make it lose adsorptive power, and gac uses long afterwards, in the easy breed bacteria in its surface, do not reach the purpose of purifying waste water.

The summary of the invention the purpose of this utility model is to release a kind of novel family expenses multi-stage filter core water purifier, has solved hollow fiber ultrafiltration film water purifier in the past, and activated carbon filter can't solve the problem of objectionable impurities in purifying waste water, bacterium, gas fully.

The purpose of this utility model is achieved in that the filter core chamber that has three head and the tail to communicate on water purifier housing body, the water inlet pipe of water purifier is connected with the feed-water end of one-level hollow fiber ultrafiltration membrane cartridge, the water side of one-level hollow fiber ultrafiltration membrane cartridge is connected with the feed-water end of active carbon filter core, the water side of active carbon filter core is connected with the feed-water end of secondary hollow fiber ultrafiltration membrane cartridge, and the water side of water purifier is connected with the water side of secondary hollow fiber ultrafiltration membrane cartridge.

The utility model also can be equipped with the maintenance end cap on water purifier housing body.

The utility model is owing to harmful organism and the heavy metal of bacterium, colloid, iron rust, red worm, moss, silt and part that has utilized in the hollow fiber ultrafiltration membrane filtration technique filtering tap water, utilize the adsorption of gac can remove gases such as chlorine residue harmful in the tap water, chloroform, trichloromethane, solved hollow fiber ultrafiltration film water purifier in the past, activated carbon filter can't solve the problem of objectionable impurities in purifying waste water, bacterium, gas fully.Increase by a secondary hollow fiber ultrafiltration film filter in water purifier, the bacterium that can stop fully to grow on the gac enters in the tap water.

Description of drawings Fig. 1 be embodiment of the utility model just analyse and observe sketch map.

Fig. 2 is the positive half section sketch map of another embodiment of the utility model.

Embodiment is described in detail embodiment of the present utility model below in conjunction with accompanying drawing:

As shown in Figure 1, the utility model comprises water purifier housing body 9-1, maintenance end cap 4-1, one-level hollow fiber ultrafiltration membrane cartridge 2, active carbon filter core 10, secondary hollow fiber ultrafiltration membrane cartridge 7, water inlet pipe 1, rising pipe 6 on water purifier housing body 9-1, has three filter core chambeies arranged side by side, each filter core chamber all has outlet to communicate with the external world, three maintenance end cap 4-1 are fixed on the exit in filter core chamber respectively by modes such as screw, screens, screw threads, make filter core chamber and the extraneous sealed state that keeps, and three chambeies couple together by pipeline 5,8 head and the tail respectively; Earlier the two ends of each

filter core

2,10,7 are blocked respectively when mounted waterproof apron 3 is arranged, prevent that water flows directly into next chamber without filter core in the chamber, three filter cores, one-level hollow fiber ultrafiltration membrane cartridge 2, active carbon filter core 10, secondary hollow fiber ultrafiltration membrane cartridge 7 is filled in respectively in the different chambeies by order from left to right respectively, covers maintenance end cap 4-1 again, water inlet pipe 1, rising pipe 6 are connected with the cavity at two ends, the left and right sides respectively.

The utility model also can be as shown in Figure 2, water purifier housing body 9-2 also can be tubular construction, rising pipe 6 is fixed on the bottom of tubular construction, water inlet pipe 1 and the maintenance end cap 4-2 one that plays the closed cylinder effect, three filter cores that when mounted the two ends card had waterproof apron 3, one-level hollow fiber ultrafiltration membrane cartridge 2, active carbon filter core 10, secondary hollow fiber ultrafiltration membrane cartridge 7 is filled in respectively in the tube by order from left to right respectively, because the barrier effect of waterproof apron 3 has been divided into three identical chambeies of scheme effect as shown in Figure 1 to cylindrical shell in fact.

Tap water enters the filtration of first chamber of water purifier housing body through one-level hollow fiber ultrafiltration membrane cartridge through water inlet pipe earlier when the user uses, after the purification of objectionable impuritiess such as some impurity, water flow to again second chamber through active carbon filter core remove anhydrate in harmful gas, water stream again flow to the 3rd chamber and through secondary hollow fiber ultrafiltration membrane cartridge bacterium, the impurity that not filtering may occur is further filtered, and the water purification after filtering fully then enters user's drinking water pipeline through the water side of water purifier.

In order to make one-level hollow fiber ultrafiltration membrane cartridge, secondary hollow fiber ultrafiltration membrane cartridge that be arranged a longer work-ing life, on water purifier housing body, put a back-purge system.
