Description
Technical field
The present invention relates to a kind of filtration unit, the water filtering element that particularly a kind of preventing microorganism grows.
Background technology
The health of human body and longevity largely depend on whether people can drink the water of clean health, in recent years, because economic growth makes the densification of industry size expansion and big city and factory, cause problem of environmental pollution greatly to increase, be faced with thus the deep problem of water pollution.
In water treatment field, be everlasting on the water outlet of water tap and connect water filtering element water is filtered, traditional tap water water filtering element generally adopts ultrafiltration membrane filter element to be filtered, mainly comprise linear hollow fiber ultrafiltration film, ultra-filtration membrane joint and water outlet tube head, two free ends of described ultra-filtration membrane are fixed on the ultra-filtration membrane joint, described ultra-filtration membrane joint is connected with the feed-water end of water outlet tube head by buckle or screw thread, the perisporium of described water outlet tube head water side is provided with two annular recessess and coordinates and make on its rising pipe that is connected to water tap with O type circle, during work, fluid is from all side inflows of ultra-filtration membrane, then flow out the water outlet tube head from the free-ended water outlet of ultra-filtration membrane two, thereby complete whole filtration procedure, there is following defect in existing ultrafiltration membrane filter element while using:
1, belong to physical filtering, can become the hotbed of microorganism after use for some time, sanitation system expert points out, general ultrafiltration membrance filter core was through time of about 7 days, the microbiological indicators such as the bacterium in water and algae can increase greatly, the microbes be trapped sticks to ultra-filtration membrane surface growth breeding, may make micropore stop up fully, even make hollow fiber cavity stop up fully, thereby will soon lose filter effect, prior art adopts the flushing repeatedly (square impact and recoil) to ultra-filtration membrane to overcome, effect is all not satisfactory, and flushing repeatedly easily makes the human consumer this be crossed to filter core to lose patience, thereby abandon the use to ultrafiltration membrane filter element,
2, nitrite concentration is higher.The ultrafiltration membrance filter technology is to process the preferred plan of organic contamination, but everything has dual character,, opacity obvious water quality serious in organic contamination, this technology can cause microbiological indicator to increase, thereby cause nitrite concentration to increase, it the most directly shows is that water-purifying machine is used for some time, and it is salty that water quality can become, not only affect mouthfeel, and the serious threat HUMAN HEALTH;
3, under the effect of large granular impurity or operation water hammer, ultra-filtration membrane easy fracture or scuffing, thus affect filter effect, can not effectively remove various chemical pollutants, shortened the work-ing life of the water filtering element that preventing microorganism grows;
4, the chlorinated lime in water has strong oxidizing property, easily the ultra-filtration membrane of rear end is produced to serious Oxidative demage.
Summary of the invention
Therefore, problem for above-mentioned existence, the invention provides a kind of rational in infrastructure, filter progress is simple, good filtration effect, long service life, can kill bacterium and virus in water, prevents the water filtering element that preventing microorganism that microorganism grows on the ultra-filtration membrane surface grows.
In order to achieve the above object, the present invention is by the following technical solutions: the water filtering element that a kind of preventing microorganism grows, the activated carbon fiber filtering membrane cylinder that comprises the hollow filter chamber, the ultra-filtration membrane housing, ultra-filtration membrane and activated carbon fiber filter, the removable closing cap that is provided with in the upper surface of described activated carbon fiber filtering membrane cylinder, the removable lower end cover that is provided with in lower surface, the lower end cover middle part has the water outlet through hole, the top that described lower end cover upper surface is positioned at the water outlet through hole extends to form to the hollow filter chamber of activated carbon fiber filtering membrane cylinder the filtration body that can place extra large Luo Jing filtrate, leave intake antrum between the upper surface of filtration body and the lower surface of upper closing cap, there is the flowing water gap between the inner side-wall of the external sidewall of described strainer tube and activated carbon fiber filtering membrane cylinder, sea Luo Jing filtrate is located at and is filtered in body, the top of described filtration body also is provided with the filter cover that can prevent that extra large Luo Jing filtrate from moving upward, the lower lumen of described filtration body is provided with the filter screen that prevents that extra large Luo Jing filtrate from moving downward, described activated carbon fiber filter, ultra-filtration membrane is located in the ultra-filtration membrane housing successively from the bottom to top, the top of described ultra-filtration membrane housing and lower end cover are dismantled and assembled to be tightly connected, bottom is provided with the water outlet tube head.
Further improved: the outer side wall of described filtration body is evenly equipped with and can be fixed on the limit ribs in activated carbon fiber filtering membrane cylinder by filtering body.
