Description
Technical field
The utility model is a kind of filtration unit of water-purifying machine, belongs to the renovation technique of the filtration unit of water-purifying machine.
Background technology
The common cartridge combination that filtration unit adopted of household water-purifying machine is the cotton filter core of PP at present; Active carbon filter core adds the combination of what filter core such as ultrafiltration filter core; This cartridge combination mode generally just is used for filtered water impurity; Play the effect of filtering bacterium, but water hardness can not produce bigger variation, the user can produce incrustation scale in the process of heating up water.
And the filter core that is usually used in softening water at present is generally three kinds, soften resin, RO film and Scale inhibitors.Though the soften resin softening water is effective,, is easy to block and influences work-ing life at the high northern area of the water hardness; The same softening water of RO film is effective, but the common ratio of waste water that produces is very high, does not meet energy conservation and environment protection; And Scale inhibitors is used for processing drinking water, is prone to bring secondary pollution, and hygienic issues can not guarantee.
Summary of the invention
The purpose of the utility model is to consider the problems referred to above and a kind of effluent quality that can guarantee is provided, and can prolong filter core work-ing life again, and reaches the filtration unit of the water-purifying machine of energy-conserving and environment-protective multiple effect.The utility model is reasonable in design, and is convenient and practical.
The technical scheme of the utility model is: the filtration unit of the water-purifying machine of the utility model; Include coarse filtration filter core, nanofiltration filter core and soften resin filter core; Wherein the water purification water outlet of coarse filtration filter core is connected with the water-in of nanofiltration filter core, and the water purification water outlet of nanofiltration filter core is connected with the water-in of soften resin filter core.
Above-mentioned coarse filtration filter core is the cotton gac composite filter element of PP, and it is three grades of filter cores that the cotton gac composite filter element of PP, nanofiltration filter core and soften resin filter core are connected in series successively.
The water outlet of above-mentioned soften resin filter core also is connected with the post active carbon filter core, and the cotton gac composite filter element of PP, nanofiltration filter core, soften resin filter core and post active carbon filter core are connected in series successively and are the level Four filter core.
Above-mentioned coarse filtration filter core includes cotton filter core of PP and active carbon filter core, and the cotton filter core of PP, active carbon filter core, nanofiltration filter core and soften resin filter core are connected in series successively and are the level Four filter core.
The water outlet of above-mentioned soften resin filter core also is connected with the post active carbon filter core, and the cotton filter core of PP, active carbon filter core, nanofiltration filter core, soften resin filter core and post active carbon filter core are connected in series successively and are the Pyatyi filter core.
The waste water mouth of above-mentioned nanofiltration filter core is back to the raw water box of water-purifying machine or is discharged into wastewater barrel through pipeline.
The utility model is owing to adopt the structure of cartridge combination mode; Tentatively filter through PP cotton and active carbon filter core, avoid causing the obstruction of nanofiltration filter core, before the nanofiltration filter core places the soften resin filter core; Remove most of calcium ions and magnesium ions earlier; Prolong the work-ing life of soften resin, remove remaining calcium ions and magnesium ions through the soften resin filter core again, can improve the mouthfeel of water outlet at last via active carbon filter core.The filter core combination of the utility model, the filter effect of performance filter cores at different levels that can be best guarantees effluent quality, and prolongs the work-ing life of whole cartridge combination, is a kind of cartridge combination mode of the best.Can be used on the various household water treatment apparatus.The utility model is that a kind of design is ingenious, excellent property, the filtration unit of convenient and practical water-purifying machine.

Embodiment
Embodiment 1:
The structural representation of the utility model is as shown in Figure 2; The filtration unit of the water-purifying machine of the utility model; Include coarse filtration filter core, nanofiltration filter core 2 and soften resin filter core 3; Wherein the water purification water outlet of coarse filtration filter core is connected with the water-in of nanofiltration filter core 2, and the water purification water outlet of nanofiltration filter core 2 is connected with the water-in of soften resin filter core 3.The waste water mouth of above-mentioned nanofiltration filter core 2 is back to the raw water box 5 of water-purifying machine or is discharged into wastewater barrel 6 through pipeline.In the present embodiment, above-mentioned coarse filtration filter core is the cotton gac composite filter element 1 of PP, and it is three grades of filter cores that PP cotton gac composite filter element 1, nanofiltration filter core 2 and soften resin filter core 3 are connected in series successively.The waste water mouth of above-mentioned nanofiltration filter core 2 is back to the raw water box 5 of water-purifying machine or is discharged into wastewater barrel 6 through pipeline.It is as shown in Figure 1 that the utility model is installed in the overall schematic of water-purifying machine.
The principle of work of the utility model is following: from the pending water of raw water box 5; At first tentatively filter through the cotton gac composite filter element 1 of PP; The PP cotton can be removed impurity particle and the suspended substance in the water, avoids stopping up the filter core that the back is provided with, and active carbon filter core can be removed the chlorine residue in the water; Avoid in the water chlorine residue that nf membrane is produced and destroy, improve the work-ing life of nanofiltration filter core; Secondly through nanofiltration filter core 2, remove the calcium ions and magnesium ions of the overwhelming majority in the water, to alleviate the filtration burden of follow-up soften resin 3; Further remove remaining calcium ions and magnesium ions in the water through soften resin filter core 3 again, through this step, water quality has reached best bating effect, and has guaranteed the work-ing life of soften resin; After post active carbon filter core 4 further improves the water outlet mouthfeel.
