Description

A kind of water purifier of filter core circulating filtration or purifier and preparation method

Affiliated technical field:

---the present invention relates to water quality, fluid purification treatment technology, specifically a kind of water purifier of filter core circulating filtration or purifier and preparation method.

Technical background:

---present micro-filtration both domestic and external or ultrafiltration or nanofiltration or each filter core of RO membrane water purifier can only be realized filtering for 1 time and namely arrive pure water inlet, particularly purified water machine is because produced pure water lacks mineral matter and trace element, because domestic have research to point out, the long-term drinking pure water may have cardiovascular and cerebrovascular and arteriosclerotic risk, generally speaking, because pure water lacks natural mineral matter and trace element, and what human hundreds of thousands was drunk since year always all is the water that contains natural mineral matter and trace element, therefore, pure water does not also claim it is best, the most suitable mankind's water, in theory, pure water is pure, safety, health, but long-term drinking and edible whether safety? is there there potential risk? also there is not in the world at present a kind of authority to convince evidence and the saying of generally acknowledging, in view of domestic and international long-term drinking to pure water can or can not have side effects with edible actually, the World Health Organization also the clear and definite theory of neither one, foundation and authoritative saying, and by the World Health Organization determine drinking water standard contain mineral matter and trace element, the water that certain degree of hardness is namely arranged, therefore, the mineralising of pure water, magnetization, calcification particularly mineralising will be a kind of trend of drinking water development, also meet the health needs of human body.Have two significant deficiency in the prior art: one is the restriction of filter core quantity, also exist and only filter the defective that once just arrives the drinking water tap that purifies, particularly the mouthfeel of pure water is still not perfect and sweet to cause water purification, another defective is that pure water is failed mineralising or mineralising filter core and just lacked well mineralising, and causing pure water generally still also is not one of optimal drinking water.This water purifier or purifier adopt and change circuit design realization filter core circulating filtration, with the particularly water quality raising of pure water of water purification, with the circulating filtration of pure water by the dechlorinations such as active carbon or mineralising or RO membrane cartridge or other filter cores of NF membrane filter core, thereby be implemented under the identical filter core condition, water purification is 2 times or multiple times of filtration and water-mineralizing and 2 times of dechlorinations or many times of effects of the RO of pure water system or nanofiltration filter core particularly.

The specific embodiment: narrate the embodiment of the invention 1 below in conjunction with accompanying drawing and a preferred embodiment:

Fig. 1 and Fig. 2 are that the water purifier of filter core circulating filtration or the structure of purifier are analysed and observe diagram:

(1), filter reset condition: all terminal valves all are in closure state.

(2), make the process of water purification or pure water:

Open original water inlet (1), former water is successively through preposition filter core (2) more than 0 grade or 1 grade, connecting pipe A (3A), 1 grade or 1 grade are with upper filter (4), connecting pipe B (3B), the water storage cavity (6B) that water purification or pure water enter into band air pressure water storage cavity or bucket (6) stores, gas in the air bag (6A) is compressed, be subject to the reaction pressure of air bag (6A) when opening pure water inlet or next stage filter core interface (5), water purification in the water storage cavity (6B) or pure water pass through threeway A (8A) by the interface channel D (3D) that contains check valve A or valve A (7A) again and enter into more than 0 grade or 1 grade preposition filter core (2) or 1 grade or 1 grade with upper filter (4), flow to connecting pipe C (3C), enter pure water inlet or next stage filter core interface (5), Here it is circulating filtration is made the complete procedure of water purification again.………………………………

(3), the process of the recovery of the air of atmospheric pressure cavity or pressurization:

---because of the impact of different materials density, gas in the air bag 6A chamber of Fig. 1 and Fig. 2 can have influence on the pressure of gas throughout the year after using, when the gas of air bag (6A) is reduced to after the several years when approaching to a certain degree, can open inflation or intake valve (6C) puts the air of nature into, also can inflate air bag, or change air bag (6A), if the air-tightness of air bag or water pocket is special good or fine, also can cancel inflation or intake valve interface or sealed interface.

Fig. 3 is that the water purifier of filter core circulating filtration or the structure of purifier are analysed and observe diagram:

(1), filter reset condition: all terminal valves all are in closure state.

(2), make the process of water purification or pure water:

Open original water inlet (1), former water is successively through preposition filter core (2) more than 0 grade or 1 grade or 1 grade, connecting pipe A (3A), 1 grade or 1 grade are with upper filter (4), connecting pipe C (3C) or connecting pipe D (3D), the water storage cavity (6B) that water purification or pure water enter into band air pressure water storage cavity or bucket (6) stores, gas in the air cavity (6A1) is compressed, be subject to the reaction pressure of air cavity (6A1) when opening pure water inlet or next stage filter core interface (5), water purification or pure water in the water storage cavity (6B) pass through threeway A (8A) again by the interface channel D (3D) that contains check valve A or valve A (7A), enter into more than 0 grade or 1 grade or 1 grade preposition filter core (2) or 1 grade or 1 grade with upper filter (4), enter pure water inlet or next stage filter core interface (5), Here it is filter core circulating filtration is made the complete procedure of water purification again.

(1), because of water meeting dissolved air, (because of frequency of utilization difference different time) can be dissolved about about 30-50 days greatly for gas in the air cavity 6A1, air in the air cavity 6A1 or other gas need regularly manual or electronic replenishing, and could recover original function.…………………………………………
