Technical Field
The utility model relates to a water purifier filtering system and a water purifier.
Background
The mineral content in the water has two sides, and the water without mineral or with low mineral content has no nutrition, so long-term drinking is not recommended, especially for the old and children; excessive mineral content in water easily causes problems of scale formation caused by water boiling, poor taste and other bad sensory problems, and can influence the use experience of consumers; in the water purifier industry, the main stream water purification technology has two types: ultrafiltration and reverse osmosis, wherein ultrafiltration retains minerals but does not remove heavy metals such as lead, cadmium, mercury, arsenic, etc.; reverse osmosis removes all elemental ions, but pure water is produced without any minerals.
The common roll nanofiltration membrane has rated retention rate, so that minerals in the filtered water are influenced by the retention rate due to the rated retention rate during filtration. For example: the rated retention rate of the nanofiltration membrane is 80 percent, if the TDS (English: total dissolved solids, abbreviated TDS, total dissolved solids) of raw water is 100 percent, the TDS of purified water after the filtration of the nanofiltration membrane is 20 percent; if the TDS of the raw water is 1000, the TDS of the purified water is 200 after the raw water is filtered by a nanofiltration membrane; because the water quality difference of each place in China is relatively large, the retention rate of mineral substances in the filtered water in each place is caused to have relatively large difference; in a high hardness area, excessive mineral retention can cause scaling, poor taste and the like. Therefore, it is necessary to design a water purifier capable of adjusting minerals.

The water purifier filter system as shown in fig. 1, comprises:
the nanofiltration filter core module 1 is used for filtering raw water, the rated working pressure of the nanofiltration filter core module 1 has the highest value, and when the actual working pressure exceeds the rated working pressure highest value of the nanofiltration filter core module, ions can pass through the nanofiltration filter core module 1, and the desalination rate can be reduced;

When raw water enters the booster pump, the working pressure of the booster pump can be coarsely regulated through the electric reflux valve, then the real-time pressure data of the booster pump can be finely regulated by controlling the adjustable waste water ratio electromagnetic valve, and finally the real-time pressure data of the booster pump can be regulated according to the real-time data of the mineral retention rate sensor, so that the whole system is more stable and reliable.
The embodiment is designed by utilizing the filtration principle of a nanofiltration membrane, and in the filtration process of the nanofiltration membrane, water molecules are pressed by the external pressure from a more concentrated solution to a more dilute solution through a reverse osmosis membrane, and the reverse osmosis membrane prevents ion diffusion by utilizing the functions of pore diameter, charge force, electrostatic repulsion and the like. The higher the feed water substance concentration, the higher the osmotic pressure; when the concentration is high to a certain value, part of substances can pass through reverse osmosis to enter a dilute solution; by the principle, we can know that when the reverse osmosis type machine works, sewage is continuously discharged, the concentration of the concentrated solution is reduced, and the equilibrium is achieved; therefore, the purpose of mineral matter adjustment can be achieved by increasing external pressure and increasing concentration of the concentrated solution to break through or destroy the balance of the reverse osmosis membrane. The structure in this embodiment has been verified by experimental data in experiments, and the desalination rate tends to decrease gradually as the pressure at the front end of the nanofiltration filter element module increases continuously.
The water purifier shown in fig. 2 comprises a machine body 8, wherein the water purifier filtering system with the structure is arranged in the machine body.
