The water-heater dechlorination filter core 100 according to the utility model embodiment is described in detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, housing 10, filtering layer 20, rear filtering layer 30 and life-span display part 40 is comprised according to the water-heater dechlorination filter core 100 of the utility model embodiment.
Be limited with chamber in housing 10, housing 10 has and the water-in 11 of chamber conducting and water outlet 12.Filtering layer 20 is located in chamber and between water-in 11 and water outlet 12, rear filtering layer 30 is located in chamber, and between filtering layer 20 and water outlet 12.To flow into from water-in 11 when water and the process flowed out from water outlet 12 can successively filtering layer 20 and after the filtration of filtering layer 30, filtering layer 20 can except the free chlorine in anhydrating, rear filtering layer 30 can remove chlorine residual in water after filtering layer 20 filters, and the setting of this two-layer filtration can reach the effect of more fully removing the free chlorine in water.
Particularly, filtering layer 20 and rear filtering layer 30 all can react with free chlorine, thus the free chlorine in water is removed.Wherein, rear filtering layer 30 is set to: colour-change can occur after rear filtering layer 30 reacts with chlorine, that is, the filtrate in rear filtering layer 30 colour-change can occur after reacting with chlorine.Thus, when different from the consumption of the filtrate that chlorine reacts in rear filtering layer 30, the color of rear filtering layer 30 can be different.Consider that the effective content of filtrate in rear filtering layer 30 constantly can reduce along with the prolongation of duration of service.Therefore, the consumption of filtrate in rear filtering layer 30 is judged by the color of rear filtering layer 30.
Because rear filtering layer 30 is located at the below of filtering layer 20, when filtering layer 20 has filter effect, the water through filtering layer 20 does not contain chlorine residue substantially, can be very slight to the consumption of rear filtering layer 30, and the colour-change of rear filtering layer 30 is also not obvious.And after filtering layer 20 lost efficacy, rear filtering layer 30 just can become main dechlorination region, and the filtrate in rear filtering layer 30 and free chlorine constantly react, and the color of rear filtering layer 30 can constantly change.Therefore, in rear filtering layer 30, the service condition of filtrate can be associated with dechlorinate life-span of filter core 100 of water-heater, obtains the work-ing life of water-heater dechlorination filter core 100 by the consumption situation of filtrate in rear filtering layer 30.
In order to can intuitively display water heater dechlorination filter core 100 work-ing life, water-heater dechlorination filter core 100 can be provided with life-span display part 40, life-span display part 40 has multiple colour developing district 411, the color in multiple colour developing district 411 is different respectively, the color in each colour developing district 411 is through calibration, and after corresponding respectively, in filtering layer 30, the filtrate of different content reacts the rear color shown with chlorine.By rear filtering layer 30 is carried out with the colour developing district 411 on life-span display part 40 service condition that color comparison can obtain filtrate in rear filtering layer 30, and then obtain the situation in work-ing life of water-heater dechlorination filter core 100.
Thus, according to the water-heater dechlorination filter core 100 of the utility model embodiment, by arranging the life-span display part 40 with the different colour developing district 411 of multiple color, the color in each colour developing district 411 can distinguish corresponding after in filtering layer 30 filtrate of different content react with chlorine the color formed afterwards, easily and clearly can obtain water-heater to dechlorinate the life situations of filter core 100 by the color of rear filtering layer 30 and the color in colour developing district 411 being carried out contrast, the accuracy of life-span judgement is high and intuitive is strong.
Dechlorination device in correlation technique is only provided with filtering layer, and filtering layer can filter the chlorine residue in water.But along with the prolongation of duration of service, the filtrate in filtering layer can consume gradually, the work-ing life of filtering layer can constantly reduce.Owing to the dechlorination device in correlation technique all not being arranged the device that can show filtering layer work-ing life, what the life-span judged to adopt is temporally (as: 3 months, 6 months) or by total flux (as: 30m
3, 50m
3) etc. method judge.
But, because the contents of residual chlorine in the different time tap water of different areas is not identical, so use above method effectively cannot judge to remove the life-span of chlorine residue device, user judges inaccurate the work-ing life to dechlorination device, easily there is the end-of-life of dechlorination device but dechlorination device still in use, thus badly influence user use water water quality, ease of use is poor.
And be provided with life-span display part 40 according to the water-heater of the utility model embodiment dechlorination filter core 100, by life-span display part 40 clear obtain the situation in work-ing life of water-heater dechlorination filter core 100, ease of use is good.
Particularly, in water (flow) direction, rear filtering layer 30 is located at the rear end of filtering layer 20, containing filtrate in rear filtering layer 30, and the water-heater dechlorination life situations of filter core 100 and being associated of filtrate.When filtrate kind one timing, the life-span of water-heater dechlorination filter core 100 can be depending on the consumption of filtrate.Because rear filtering layer 30 can react with free chlorine, colour-change occurs, when the filtrate in rear filtering layer 30 constantly reduces along with the prolongation of duration of service, the color of rear filtering layer 30 can correspondingly change.
The color of the plurality of change corresponds respectively to the color in the multiple colour developing districts 411 on life-span display part 40.The color in each colour developing district 411 is all through calibration, and the filtrate that may correspond to respectively in different weight percentage content reacts with free chlorine the color shown afterwards.By the color in the colour developing district 411 on the color of rear filtering layer 30 and life-span display part 40 being compared, the usage quantity of filtrate and the residual content of filtrate in rear filtering layer 30 can be judged, and then obtain the work-ing life of water-heater dechlorination filter core 100.
In this life-span deterministic process, the color of rear filtering layer 30 is easy to observe, and color comparison is easy, and life-span accuracy of judgement degree is high and intuitive is strong.Water-heater dechlorination filter core 100 can be formed as the structure that single filter and cascade filtration add instruction, dechlorination thoroughly and life-span display accurately.
As shown in Figure 1, housing 10 can be formed as round shape, and the material of housing 10 can be selected from polypropylene, polyethylene, ABS, and housing 10 can be used for parcel filtering layer 20 and rear filtering layer 30.
Water-in 11 can be located at the upper end of housing 10, and water outlet 12 can be located at the lower end of housing 10.The size of water-in 11 can be G1/2, and the size of water outlet 12 can be G1/2, and water-in 11 can be arranged by interior tooth, and water outlet 12 can be arranged, so that be connected with miscellaneous part by outer tooth.
Water-heater dechlorination filter core 100 also can comprise filter 50, and filter 50 is located at chamber interior.Filter 50 can extend along the radial direction of chamber, and the periphery of filter 50 is connected with the internal perisporium of housing 10, chamber to be divided into two portions of spaced apart along the vertical direction distribution, i.e. and upper chamber and lower chambers.Water-in 11 and upper chamber's conducting, water outlet 12 and lower chambers conducting.
Filtering layer 20 is filled in upper chamber, and rear filtering layer 30 is filled in bottom chamber.Water can flow in upper chamber from water-in 11, lower chambers is entered into after the filtration of the filtering layer 20 in upper chamber, do not filter water completely again to be filtered by the rear filtering layer 30 of bottom chamber, the water completely that finally dechlorinates can flow out water-heater dechlorination filter core 100 from water outlet 12.The periphery of filtering layer 20 can be fitted on the internal perisporium of upper chamber, and the periphery of rear filtering layer 30 can be fitted on the internal perisporium of lower chambers, to be filtered completely by the water flowing through water-heater dechlorination filter core 100.
The lower end that filter 50 can be close to housing 10 is arranged, and with the volume making the volume of filtering layer 20 be greater than rear filtering layer 30, makes filtering layer 20 can play main dechlorination effect.Filter 50 can be the cotton material of PP, mainly plays the effect separating filtering layer 20 and rear filtering layer 30, can not do requirement to filtering accuracy.
Conveniently filtering layer 30 and the color in colour developing district 411 after comparison, alternatively, housing 10 can be provided with the window 13 for observing bottom chamber color.The color of rear filtering layer 30 can be observed easily by window 13.Life-span display part 40 can be established on the housing 10 and contiguous window 13 is arranged.Thus, the colour developing district 411 of life-span display part 40 can be close to window 13, is convenient to directly rear filtering layer 30 and colour developing district 411 be carried out colour contrast, accurately to judge the life situations of rear filtering layer 30.
Window 13 can be inlayed on the housing 10, window 13 can be polycarbonate or synthetic glass, the window 13 of polycarbonate or synthetic glass material can be formed as water white transparency part, good in optical property, transparency are high, be convenient to clear and observe rear filtering layer 30 color accurately, meanwhile, window 13 bonding strength is higher, can ensure that rear filtering layer 30 bears running water pressure and impacts.
As shown in Figure 2, life-span display part 40 can comprise than vitta 41 and numerical value bar 42, and numerical value bar 42 is contiguous to be arranged than vitta 41.The different colour developing district 411 of multiple color is provided with than vitta 41.Numerical value bar 42 has multiple different numerical value, and multiple different numerical value is corresponding with the colour developing district 411 of different colours respectively, to indicate the life situations of rear filtering layer 30.By comparing with than the colour developing district 411 on vitta 41 to rear filtering layer 30, then the colour developing district 411 obtained is carried out the corresponding life situations that can obtain rear filtering layer 30 with the numerical value on numerical value bar 42.
Wherein, can graduated colors be set to than the colour developing district 411 on vitta 41, numerical value bar 42 can be marked with the printed words of 100%-0%, to represent the life-span of water-heater dechlorination filter core 100.Wherein, 100% usage quantity that can represent filtrate in rear filtering layer 30 is 0%, namely residual content is 100%, the life-span of water-heater dechlorination filter core 100 is 100%, 0% filtrate that can represent in rear filtering layer 30 is made to use up completely, the end-of-life of water-heater dechlorination filter core 100, needs to change filtering layer 20 and the filter core in rear filtering layer 30.
In concrete examples more of the present utility model, filtering layer 20 is active carbon layer, and rear filtering layer 30 is copper zinc alloy layer, is namely carbon leaching material in upper chamber, and bottom chamber is copper zinc alloy (KDF) filtrate.In water (flow) direction, copper zinc alloy is placed in the rear end of gac, and water is first through gac, then through copper zinc alloy, gac and copper zinc alloy all can carry out filtration dechlorination to water.
Gac, as a kind of filtrate removing the excellent property of chlorine residue, can play main dechlorination effect to water.Can there is colour-change in copper zinc alloy, by the life-span of filtering layer 30 after the change instruction of the color of copper zinc alloy in the process removing chlorine residue in water.Free chlorine residual in water plays a key effect to KDF colour-change, and its reaction formula is:
Zn+Cl
2→Zn
2++2Cl
-
ZnCu+A
2+(representing heavy metal) → Zn
2++ ACu
The reason that colour-change is possible is, can appear the color of copper after the zinc on the surface of copper zinc alloy Zn-Cu-Zn comes off, and can variable color further after other metal ions or organism in polluted by copper water, finally becomes black.
When gac has filter effect, the water through KDF does not contain chlorine residue substantially, can be very slight to the consumption of KDF, and the colour-change of KDF is also not obvious.And after gac lost efficacy, KDF can be used as filtrate and to make a return journey the chlorine residue in dewatering, thus cause constantly deepening of KDF color.According to test, when KDF darkens black, the clearance of chlorine residue reduces greatly, can think that KDF lost efficacy at this point, the end-of-life of water-heater dechlorination filter core 100.
Gac can be granulated active carbon, and iodine number can be greater than 800mg/g.In order to play the effect of desirable removal chlorine residue, the thickness of active carbon layer can be greater than 10cm, and the size that namely active carbon layer extends in water (flow) direction is greater than 10cm.And in order to allow current pass through active carbon layer uniformly as far as possible, the diameter of active carbon layer can be less than 90cm, namely active carbon layer can be less than 90cm perpendicular to the size that water (flow) direction extends, and specifically the radial dimension of housing 10 can be set to 90cm or be less than 90cm when designing.
The copper zinc alloy that mass ratio is 1-10% can be provided with or mass ratio is the active carbon loading silver of 0.01-1% in filtering layer 20.That is, filtering layer 20 can be the activated-carbon filter bed of material, add the copper zinc alloy filtrate of 1%-10%, or filtering layer 20 can be active carbon loading silver layer in this carbon leaching material, and a year silver-colored ratio for this year silver-colored activity charcoal is 0.01%-1%.This filtering layer 20 can have bacteriostatic action, prevents the inner breed bacteria of water-heater dechlorination filter core 100, the health of the health of guarantee water.
As shown in Figure 2, water-in 11 place can be provided with upper filter screen 60, for tackling the suspended matter in water, can play the effect of certain dispersing water flow simultaneously, current uniformly across filtering layer 20, can be dechlorinated effective.The aperture of upper filter screen 60 can be 80-150 micron, and material can be the one in stainless steel, nylon, polyester or polyethylene.
Water outlet 12 place can be provided with lower filter screen 70, can play the effect of particulate matter in further trap water.The aperture of lower filter screen 70 can be less than the aperture of upper filter screen 60, and particularly, the pore diameter range of lower filter screen 70 can be 30-100 micron, and material can be the one in stainless steel, nylon, polyester or polyethylene.
When using the dechlorination of water-heater as shown in Figure 2 filter core 100, water can flow in chamber from water-in 11, in chamber can successively through upper filter screen 60, filtering layer 20, filter 50, after filtering layer 30, lower filter screen 70, finally from water outlet 12 flow out water-heater dechlorination filter core 100.When water-heater dechlorination filter core 100 duration of service is shorter, the chlorine residue in water substantially can be removed when through filtering layer 20, and now, the consumption of filtering layer 30 is very slight, and the colour-change of rear filtering layer 30 is not obvious.
And when water-heater dechlorination filter core 100 duration of service is longer, after causing filtering layer 20 to lose efficacy, rear filtering layer 30 just can become main dechlorination region, and the filtrate in rear filtering layer 30 and free chlorine constantly react, and the color of rear filtering layer 30 can constantly change.The colour-change of rear filtering layer 30 is observed by window 13, by the color of rear filtering layer 30 and the color than district 411 that vitta 41 develops the color are compared, and the colour developing color in district 411 and the numerical value on numerical value bar 42 are carried out the corresponding water-heater that can obtain and to dechlorinate the life situations of filter core 100.
Comprise body and the water-heater dechlorination filter core 100 according to the utility model embodiment according to the water-heater of the utility model embodiment, water-heater dechlorination filter core 100 is connected with body.Particularly, be limited with water storage chamber in body, body has the feed-water end with water storage chamber.
Consider that carbon leaching material is not suitable at high temperature using, therefore, the water outlet 12 of water-heater dechlorination filter core 100 can be communicated with feed-water end, and water-in 11 can be connected with water service equipment.Thus, tap water flow in water-heater dechlorination filter core 100 by water-in 11, and the temperature flowing through the water of carbon leaching material is lower, and gac can normally use and unaffected.
After water-heater dechlorination filter core 100 filters dechlorination, water can flow out from water outlet 12, is then flowed to the water storage cavity indoor of body by feed-water end, after the filtration dechlorination of water-heater dechlorination filter core 100, flow into the water clean hygiene more of water-heater, significantly improve by quality.
Because the water-heater dechlorination filter core 100 according to the utility model embodiment has above-mentioned useful technique effect, therefore few according to the free chlorine contents of water in the water-heater of the utility model embodiment, high by quality, there is the function in display water heater dechlorination filter core 100 life-span, facilitate user's more hot water exchanger dechlorination filter core 100.
