Abstract
The invention discloses an active carbon filter core for water purifier. The filter core comprises a PP cotton cylinder; the external surface of the PP cotton cylinder is wrapped by an active carbon layer and a PP cotton coating from inner to outer, and the thickness of the active carbon layer is 5 to 10 mm. The active carbon is directly wrapped between two layers of PP cotton, so the active carbon layer does not to be adhered by an adhesive, and the active carbon powder is not coated by an adhesive. During the application process, the active carbon powder can fully contact the water body, and the absorption performance of the active carbon cloth is greatly improved. The wrapping of the active carbon layer is carried out through a physical technology, no chemical agent is used, so the environment is not polluted and the production cost is reduced.
Description
Technical field
The present invention relates to filtering element for treating water, especially, relate to a kind of active carbon filter core for water-purifying machine.
Background technology
Gac is the environment-friendly materials of a kind of high adsorption capacity, toxicological harmless, is widely used in the fields such as purifying air, deodorizing, sewage disposal, chemical industry catalysis.At present, along with the improvement of the increasingly serious of water pollutions and living condition, day by day universal in our life as the household water-purifying machine of filter core using gac.
In conventional art, the making of active carbon filter core is generally roll with active carbon cloth to form.At present, the active carbon cloth on market generally adopts wet dip to make; First, gac is dispersed in the coating fluid containing dispersion agent, emulsifying agent, binding agent equal solvent; Then, the base material of the types such as PP cloth, non-woven fabrics is dipped in coating fluid, by the bounding force of binding agent activity charcoal powder is adhered on base material and forms active carbon cloth, then active carbon cloth is dried, finally use active carbon cloth to roll into active carbon filter core.Adopt the active carbon filter core made in this way and there is following deficiency:
On the one hand, activity charcoal powder is bonded by tackiness agent and base material, and activity charcoal powder can be wrapped up by tackiness agent, and activity charcoal powder is difficult to contact with water body, and the adsorptive power of activity charcoal powder is greatly diminished; And the content of activity charcoal powder is lower; Therefore, the filter core detergent power adopting this active carbon cloth to make is very poor.On the other hand, need in the making processes of active carbon cloth to use more organic solvent, easily secondary pollution is caused to environment, and complex process, cost is higher.
Summary of the invention
The object of the invention is to provide a kind of active carbon filter core for water-purifying machine, and to solve in prior art, active carbon filter core adsorptive power is poor, and cost is high, easily causes the problem of environmental pollution in making processes.
For achieving the above object, the invention provides a kind of active carbon filter core for water-purifying machine, comprising: PP lap cylinder, the outside surface of described PP lap cylinder is coated with active carbon layer and PP bale of cotton coating from inside to outside successively; The thickness of described active carbon layer is 5mm-10mm.
Further, the wall thickness of described PP lap cylinder is 5mm-10mm.
Further, the diameter of bore of described PP lap cylinder is 20mm-34mm.
Further, the thickness of described PP bale of cotton coating is 5mm-10mm.
The present invention has following beneficial effect:
Gac is directly wrapped between two-layer PP cotton, and active carbon layer does not need to adopt binding agent to adhere to, not bonded dose of activity charcoal powder parcel; In use procedure, activity charcoal powder fully can contact with water body, greatly improves the adsorptive power of active carbon cloth; The parcel of active carbon layer is physical treatment technology, does not use chemical reagent, can not impact, and reduce production cost to environment.
Accompanying drawing explanation
Below with reference to figure, the present invention is further detailed explanation.The accompanying drawing forming a application's part is used to provide a further understanding of the present invention, and schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 is the schematic cross-section of the present invention for the active carbon filter core preferred embodiment of water-purifying machine.
Description of reference numerals:
101, PP lap cylinder; 102, active carbon layer; 103, PP bale of cotton coating; 104, endoporus.
Embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail.
Refer to Fig. 1, the preferred embodiments of the present invention provide a kind of active carbon filter core for water-purifying machine, comprising: PP lap cylinder 101, and the outside surface of described PP lap cylinder 101 is coated with active carbon layer 102 and PP bale of cotton coating 103 from inside to outside successively; The thickness of described active carbon layer 102 is 5mm-10mm.
During use, filter core is placed in the pressurized vessel of water-purifying machine, and during filtered water, water is first through PP bale of cotton coating 103, and first the impurity in water body adsorbed by PP bale of cotton coating 103; Then, water body is through active carbon layer 102, and the bacterium in water body and peculiar smell are adsorbed by active carbon layer 102; Finally, water, through PP lap cylinder 101, flows out from from endoporus 104 after the activated carbon granule in water is filtered.
Adopt the active carbon filter core of this structure, gac is directly wrapped between two-layer PP cotton, and active carbon layer 102 does not need to adopt binding agent to adhere to, not bonded dose of activity charcoal powder parcel; In use procedure, activity charcoal powder fully can contact with water body, greatly improves the adsorptive power of active carbon cloth; And the parcel of active carbon layer 102 is physical treatment technology, does not use chemical reagent, can not impact, and reduce production cost to environment.
Preferably, for ensureing the strainability of filter core, the wall thickness of described PP lap cylinder 101 is 5mm-10mm; The diameter of the endoporus 104 of described PP lap cylinder 101 is 20mm-34mm; The thickness of described PP bale of cotton coating 103 is 5mm-10mm.
As can be seen from the above description, the above embodiments of the present invention achieve following technique effect:
1, gac is directly wrapped between two-layer PP cotton, and active carbon layer 102 does not need to adopt binding agent to adhere to, not bonded dose of activity charcoal powder parcel; In use procedure, activity charcoal powder fully can contact with water body, greatly improves the adsorptive power of active carbon cloth.
2, the parcel of active carbon layer 102 is physical treatment technology, does not use chemical reagent, can not impact, and reduce production cost to environment.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention; For a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
