Description

The terminal divided water supply device

Technical field

The utility model relates to the purifying processing device of tap water, refers to a kind of terminal divided water supply device that is installed on the running water pipe network users end particularly.

Background technology

At present, raising day by day along with social living standard, particularly the water quality requirement of direct drinking water is also more and more higher to the daily life water for people, and various small-sized water supply purifying processing devices are just constantly come into places such as family, hotel, hotel, office, school.The small-sized water supply purifying processing device of the existing overwhelming majority mainly is to adopt various common filter cores the impurity in the tap water, bacterium etc. are held back or to be adsorbed, but impurity and the bacterium holding back or be adsorbed on the filter core generally are difficult to remove, need frequent disassembly, cleaning or renew cartridge more, otherwise after impurity, bacterium etc. runs up to a certain degree, not only can stop up filter core, influence purification efficiency and water purification water yield, even more serious is the secondary pollution that also can cause water, and as seen these devices lack permanently effective safety and sanitation guarantee.Also some small-sized water supply purifying processing device directly adopts ultrafilter that tap water is handled, but such device mostly is disposable fixedly enclosed construction greatly, and there is not a preposition rough filtering device, in the long-term process of using, impurity such as iron rust in the tap water are easy to damage hyperfiltration membrane assembly on the one hand, make its cisco unity malfunction, application life significantly; Also still cause into water impurity obstruction ultrafiltration periosteum on the other hand easily, influence the water yield of purification efficiency and pure water; And it can not change and clean filter core, and filter core can only integral body still fall after stopping up, and wasting phenomenon is very serious.

Summary of the invention

The purpose of this utility model is exactly that a kind of terminal divided water supply device that can supply with direct drinking water and living water use simultaneously to the user will be provided, this device can be removed bacterium and the impurity in the water effectively, guarantee direct drinking water long-term safety health, and this device can effectively be avoided the infringement of impurity in the water, long working life, economical and practical.

For realizing this purpose, the terminal divided water supply device that the utility model is designed, include a ultrafilter shell, hollow fiber ultrafiltration tunica fibrosa pipe is equipped with in the inside of ultrafilter shell, two of ultrafilter shell is respectively equipped with the hollow end cap, wherein one hollow end cap links to each other with running water pipe, the hollow end cap of other end links to each other with water service pipe, ultrafiltration water out on the ultrafilter shell links to each other with an end of active carbon loading silver strainer, the other end of active carbon loading silver strainer links to each other with the direct drinking water pipe, its special character is: cover in the hollow end of running water pipe one end and be respectively equipped with one stainless steel screen pack and a micropore ceramic filter element, running water pipe communicates through the interior hollow fiber ultrafiltration tunica fibrosa pipe of stainless steel screen pack and micropore ceramic filter element and ultrafilter shell successively.

Advantage of the present utility model is: owing to adopted stainless steel screen pack and the preposition filter assemblies of micropore ceramic filter element two-stage that tap water is carried out coarse filtration before hollow fiber ultrafiltration tunica fibrosa pipe, impurity such as iron rust that on the one hand can volume in the tap water is bigger, sand grains are blocked in outside the hollow fiber ultrafiltration tunica fibrosa pipe, effectively the diaphragm pipe is not subjected to the damage of these impurity, prolongs its application life; Probability through the obstruction of the tap water after coarse filtration film pipe greatly reduces on the other hand, can solve the problem that film pipe difficulty is unpicked and washed well, also significantly improved the operating efficiency of film pipe, the thorough filtering of gained direct drinking water pollutants such as the iron rust in the water, colloid, larger molecular organics and bacterium, the trace element and the mineral matter that have kept useful health, water quality is fresh can directly drink raw, and has effectively avoided the secondary pollution of bottled water; Adopt dynamic crossing filtering principle simultaneously in the device, the direct drinking water that filters through hollow fiber ultrafiltration tunica fibrosa pipe is 90 ° with the domestic water flow direction without its filtration, the macromolecular substances that is trapped within the film inwall is discharged with living water use, promptly only need use living water use to clean automatically slightly to the film pipe, thereby make this device long-term safety health, economical and practical.
