Abstract
The utility model discloses a composite scale restraining filter element which comprises an inner filtering layer and an outer filtering layer, scale restraining agent filled between the inner and outer filtering layers, and an upper end cover and a lower end cover for fixing the filtering layers and filter material. Grooves are densely formed on the surface of the filtering layer and sealing pieces are arranged at two ends of the inner and outer end covers. The composite filter element adopts poly-layer filtration and the filtration precisions of the outer and inner filtering layers are in gradient distribution, thereby realizing filtration and high pollutant carrying capacity; the grooves are densely formed on the surface of the outer filtering layer, so as to increase the surface area and strength, and ensure that the service life of the scale restraining filter element is greatly improved compared with the traditional filter element; the scale restraining agent is arranged between the filtering layers, so as to achieve the purpose of scaling prevention of purified water; and the structure is simple and the installation and maintenance are convenient.
Description
Technical field
The utility model relates to a kind of multi-functional composite filter element of household water filter.
Background technology
Particularly ultrafiltration class of household water filter water purifier more and more becomes the main flow of novel house ornamentation.But because China's tap water qualitative diversity and complexity, single purification techniques has been not enough to reach the purification of water quality purpose, therefore, and some defectives of present water purifier existence more or less:
1, utilizes the cartridge combination of multiple difference in functionality, as " PP cotton+granular activated carbon+milipore filter+post active carbon " technology, to satisfy design requirement; certainly will cause the water purifier complex structure like this; bulky, the installation and maintenance difficulty, and leave certain potential safety hazard.
2, for solving the calcium in the hard water, the scale problems of magnesium ion, a large amount of water purifier adopts ion-exchanges to soften, the loss of cause purifying waste water middle calcium, magnesium ion, and sodium ion exceeds standard, in fact when reducing the water hardness, brought other negative hidden danger.
3, the milipore filter water purifier can be removed bacterium and above impurity, but can not reduce original water hardness, and it is purified waste water and can produce white floating thing, the organoleptic indicator that influence is purified waste water in boiling part.
The utility model content
The purpose of this utility model is that a kind of filter core that integrates purification and scale suppression function will be provided, and can be used as the independent process unit of water purifier, uses separately or is used with other water purifiers, reaches to purify and the scale suppression purpose.
For reaching above-mentioned purpose, the utility model adopts following technical scheme: this compound scale suppression filter core comprises inside and outside filter course and is filled in scale suppression agent between the inside and outside filter course, the fixing upper and lower end cap of filtering layer and filtrate.
Described outer filter course is made by the PP material, is cylindric, and filtering accuracy is 5 microns, and the outer surface groove that gathers contacts with inhalant region.
Described inner filtration layer is made by the PP material, is smooth cylindric, and filtering accuracy is 1 micron, and its inner surface contacts with the product pool.
Described scale suppression agent is graininess or powdery solid, and material can be the scale suppression class material of poly-microcosmic salt and other compound national hygienic requirements.The scale suppression agent is filled in inside and outside filter course and the cavity that upper and lower end cap one common peripheral becomes.
The two ends of described filter course and scale suppression agent are provided with end cap, are divided into upper end cover and bottom end cover.End cap can symmetry or asymmetric up and down.End cap is provided with projection and horn-like bulge loop, is used for fixing outer filter course and inner filtration layer.
Described upper end cover top can be set to male convex, by inserting or engage thread, is connected with the filter housing end cap.
With the junction of inside and outside filter course, is furnished with seal on the described end cap.
Filter core of the present utility model filters water like this: after former water enters from the filter water inlet,, behind the upper end cover internal orifice, flow out from the filter delivery port from the centre bore of inner filtering layer by behind out filtering layer, scale suppression agent and the inner filtering layer with this again.
Compared with prior art, composite filter element of the present utility model adopts multiple filtration, the filtering accuracy distribution gradient of out filtering layer and inner filtering layer, have and filter and the high double action of pollutant holding capability, and groove gathers on the surface of out filtering layer, help to improve surface area and intensity, service life, more traditional filter core was much improved like this;
Be provided with the scale suppression agent in the filtering layer, reach the purpose of the fouling that prevents to purify waste water, and calcium, magnesium ion in the water are not eliminated in scale suppression agent itself, kept valuable mineral matter, simultaneously, do not reduced hardness by increasing sodium ion to the human body beneficial, the problem that exceeds standard of sodium ion in the effectively anti-sealing, make purify waste water safer, and simple in structure, convenient for installation and maintenance.
Description of drawings
Accompanying drawing 1 is a kind of structure cutaway view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described.
Embodiment:
As shown in Figure 1, the compound scale suppression filter core of present embodiment comprises by out filtering layer 3, the inner filtering layer 5 of the manufacturing of PP material and is installed on scale suppression agent 4 between the inside and outside filtering layer; Groove gathers on out filtering layer 3 surfaces; The top of filter core is provided with upper end cover 2, and the bottom is provided with bottom end cover 6, and inner filtering layer 5 inserts in the horn-like protruding ring of end cap, and out filtering layer is connected between the end cap by the projection of end cap.Upper and lower end cap both sides are respectively equipped with seal 1 and seal 27.
Claims (3)
1. compound scale suppression filter core is characterized in that: comprise be cylindric, by the outer filter course that the PP material is made, groove gathers on the surface of described outer filter course; Have in the filter course outside and be inner filtration layer cylindric, that adopt the PP material to make; Outside described, the inner filtration interlayer is filled with the scale suppression agent; The fixedly upper and lower end cap of filtering layer and filtrate arranged in that described filter course is upper and lower; The outer surface of described outer filter course contacts with inhalant region, and the inner surface of described inner filtration layer contacts with the product pool.
2. compound scale suppression filter core according to claim 1 is characterized in that: described upper and lower end covers and is provided with the projection that is used for fixing outer filter course and the fixing horn-like bulge loop of inner filtration layer.
