Scale inhibition filter element device

Technical Field

The utility model relates to a filter core technical field, in particular to dirt filter core device hinders.

Background

Scale has been one of the hot water quality problems of concern. When in daily useWhen the alkalinity and hardness of water are too high, a large amount of calcium, magnesium and bicarbonate ions contained in the water are combined to form scale in the heating and boiling process. The main component of the scale is CaCO ₃ And MgOH ₂ . The water quality is turbid due to the water scale, and the sense is influenced. The scale deposits in the heating appliance, so that the heating appliance is heated unevenly, the heat conductivity of the heating appliance is reduced, and troubles are brought to the life of residents.

The existing polyphosphate scale inhibition filter element on the market does not consider the inhibition effect of organic matters on the scale inhibition effect of polyphosphate, and the scale inhibition effect is not ideal when hard water with high organic matter content is treated. Therefore, a novel scale inhibition filter element device with a front activated carbon adsorption layer is needed.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model aims to provide a scale inhibition filter core device which can improve the scale inhibition effect of polyphosphate and can not generate scale when retaining calcium and magnesium ions.

In order to realize the purpose, the utility model discloses a technical scheme is:

the utility model provides a dirty filter core device that hinders, includes filter flask 1 and is located filter flask 1 inside filter core 2, filter flask 1 includes bottle 10 and the bottle lid 9 that is located bottle 10 top, and bottle lid 9 and bottle 10 adopt threaded connection, be equipped with water inlet 7 and delivery port 8 on the bottle lid 9, water inlet 7 and delivery port 8 set up in 9 axis both sides of bottle lid, symmetric distribution, form inhalant canal between 2 outer walls of filter core and the 1 inner wall of filter flask, water inlet 7 is linked together with inhalant canal, and 2 upper ends of filter core and 9 vacuoles of bottle lid, delivery port 8 are linked together with the cavity.

The filter element 2 is of a multi-layer cylindrical structure, and is sequentially provided with a first PP cotton layer 3, an activated carbon layer 4, a second PP cotton layer 5 and a scale inhibiting material 6 from outside to inside.

After water flows through a water inlet channel formed between the outer wall of the filter element 2 and the inner wall of the filter bottle 1 from the water inlet 7, the water uniformly flows from the periphery of the filter element 2 to the center along the horizontal direction, flows through the first PP cotton layer 3, then flows through the activated carbon layer 4, finally flows through the second PP cotton layer 5, then fully contacts with the scale inhibiting material layer 6, then vertically flows upwards through a cavity formed by the upper end of the filter element 2 and the bottle cap 9, and then horizontally flows into the water outlet 8.

The thickness of the PP cotton is 8mm, the thickness of the activated carbon layer 4 is 10mm, and the weight of each slightly soluble spherical crystal is 10-15g.

The utility model has the advantages that:

hydrophobic organic substances reduce the scale inhibition efficiency of the polyphosphate. Therefore, the active carbon layer is added before the polyphosphate scale inhibition layer, raw water firstly flows through the active carbon layer, hydrophobic natural organic matters contained in the raw water are adsorbed and removed, and then the raw water flows through the polyphosphate scale inhibition layer, so that the scale inhibition effect is obviously improved.

And the multi-stage filtration of PP cotton and active carbon can remove the chromaticity, peculiar smell and residual chlorine of the raw water, thereby improving the water quality in multiple aspects.

Fig. 3 is a schematic view showing the flow direction of water.

In the figure: the water-saving filter comprises a filter bottle 1, a filter element 2, a first PP cotton layer 3, an activated carbon layer 4, a second PP cotton layer 5, a scale inhibition material 6, a water inlet 7, a water outlet 8, a bottle cap 9 and a bottle body 10.

Detailed Description

The present invention will be described in further detail with reference to examples.

As shown in fig. 1-3: a scale inhibition filter element device comprises a filter bottle 1 and a filter element 2. The filter bottle 1 comprises a bottle cap 9 and a bottle body 10. The cap 9 and the body 10 are screwed. The bottle cap 9 is provided with a water inlet 7 and a water outlet 8. When the water-saving device is installed, the water flow direction is noticed, and the water inlet and the water outlet can not be reversed.

The scale inhibition device can be arranged at a user inlet pipe of a user and has a scale inhibition effect on the whole household water. Can also be arranged at the water inlet pipe of a shower water heater, a water dispenser, a washing machine and a kitchen faucet, and plays a role in inhibiting scale on the water outlet of a water using appliance.

The filter element 2 is of a multi-layer cylindrical structure, and is sequentially provided with a first PP cotton layer 3, an activated carbon layer 4, a second PP cotton layer 5 and a scale inhibition material 6 from outside to inside. Active carbon layer 4 is being wrapped up in to two-layer PP cotton, prevents that active carbon layer 4 from running off, and the PP cotton also plays the effect of preliminary impurity such as filtration silt, bacterium simultaneously.

The scale inhibiting material 6 is a slow-release slightly soluble spherical crystal, the effective component of which is polyphosphate and is formed by baking sodium dihydrogen phosphate dihydrate at 900 ℃. The oxygen-phosphorus bond of the polyphosphate has strong capability of complexing metal ions, and forms a stable soluble chelate with calcium and magnesium ions in water, so that the content of dissociative hardness ions is reduced. Meanwhile, long-chain anions of the polyphosphate can be adsorbed on the calcium carbonate microcrystals to prevent the microcrystals from combining with each other and prevent the calcium carbonate from continuously growing to form scale particles.

As shown in fig. 1 and 3: in the present embodiment, the water filtration process is: water gets into from water inlet 7, through the lateral wall of the cotton layer 3 of first PP, activated carbon layer 4, the cotton layer 5's of second PP multiple filtration of the cotton layer of whole cylinder filter core lateral wall evenly intakes through the bottle 10 and the lateral wall of filter core 2 clearance flow direction filter core, and rivers get into inside the filter core, with 6 full contact of antisludging material, flow direction filter core upper end, flow out from delivery port 8 at last.

The coagulant dosage of a water supply plant is generally not more than 10mg/L. The addition amount can not completely remove natural organic matters in the water, and particularly for the water with high alkalinity, the effect of removing the organic matters by coagulation is not ideal. And the hydrophobic macromolecular natural organic matters in the water can inhibit the scale inhibition efficiency of the polyphosphate. Therefore, the scale inhibition material 6 is arranged in front of the activated carbon layer 4 and is used for adsorbing hydrophobic natural organic matters in water and improving the scale inhibition efficiency of polyphosphate. The activated carbon layer 4 can also remove the chromaticity, peculiar smell and residual chlorine of raw water, and improve the water quality from multiple aspects.

(1) Raw water taken from a river was not treated, and the sample was designated as A.

(2) Polyphosphate was added to the raw water, sample number B.
