Abstract
The utility model discloses a high-flux filter element which comprises a filter layer, an upper end cover, a lower end cover and a sealing ring. The filter layer is a folded film filter element which is circularly folded in a low valley, peak, low valley, peak, high valley, peak and low valley folding mode. The high-flux filter element has the advantages of high water flux and pressure resistance and stable outlet water. The filter area of the high-flux filter element is increased by about 30% as compared with an existing folded film filter element, water yield of an inner-ring film is increased by 30%-50%, water quantity difference between the inner-ring film and an outer-ring film is reduced, and the problem of bias current is solved. Besides, the high-flux filter element is an internal pressure type filter element, in other word, water flows in the high-flux filter element internally and flows out of the high-flux filter element externally, so that impurities are stopped in the filter element, and can be taken away when the filter element is lifted up, and the problem of water pollution is avoided.
Description
Technical field
The utility model relates to a kind of large flux filter core, especially a kind of large flux filter core.
Background technology
Large flux filter core is compared with standard filter cartridges, because it is high that it processes flow, the usage quantity that can reduce filter core also can reduce the size of filter housings greatly, greatly reduce cost of investment, therefore be widely used in the pre-treatments filtrations such as industrial RO water treatment system, seawater desalination system, running water.
The loop collapsing mode of the common employing peak-paddy of existing folded membrane filter core, because the inside/outside diameter size of large flux filter core differs more than 40%, when filtered water, the water yield on the film of filter core outer ring is more much larger than the water yield on the inner ring film, easily cause the current generation bias current on the film of outer ring, cause water distribution inhomogeneous, filter core is local to be stopped up.
The utility model content
Technical problem to be solved in the utility model provides a kind of large flux filter core, makes that structural strength is higher, the foldable filter element filter area increases, and water flux is larger, and retaining power is stronger.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of large flux filter core, comprise filter course, upper end cover, bottom end cover and sealing ring, described filter course is the folded membrane metafiltration core of the folding mode loop collapsing of employing low ebb-peak-low ebb-peak-Gao Gu-peak-low ebb.
As preferably, this large flux filter core also comprises inner support layer, outer support layer, and described filter course is between described inner support layer, outer support layer.Because filter core has outer reinforcement supporting layer, do not need to add the stainless (steel) wire borehole jack in the supporting filter.
As preferably, described inner support layer is the silk screen of plastic material, and described outer support layer is the strengthening grid of plastic material.The screen net structure that the inner support layer adopts; energy is the water conservancy diversion current evenly; make filter core stressed even all around; the strengthening grid that the outer support layer adopts can support the pressure that produces when filtering, the protection filter membrane; prevent from producing when pressure reduction is excessive and break; produce the water place in order to avoid the booty of holding back enters, good strengthening grid has prevented that also filter core in use can be because increasing pressure reduction produces distortion simultaneously, guarantees that filter core can not cannot take out because external diameter becomes to be stuck in the filter greatly.
Described inner support layer is the silk screen of polypropylene or nylon material, and described outer support layer is the strengthening grid of polypropylene or nylon material.
As preferably, described upper end cover center is provided with through hole, and described upper end cover is provided with handle, described handle be positioned at described through hole directly over.
As preferably, the bottom surface of described upper end cover is provided with the stopper slot of the spacing described filter course of a circle.Filter core is positioned at the stopper slot of upper end cover, and is fixing more firm.
As preferably, the end face of described upper end cover is evenly equipped with some cylindrical slot.
The utlity model has following beneficial effect: water flux larger, withstand voltage higher, water outlet is more stable.Compare with existing folded membrane filter core, increased by about 30% filter area, increased simultaneously the water yield of 30%-50% at the inner ring film, the water yield that has reduced the Internal and external cycle film is poor, has solved the problem of bias current.The inner pressed filter core, namely water flow mode advances to go out in being, makes impurity be trapped within the filter core the inside, and when filter core was mentioned, impurity was just taken away in the lump, the phenomenon of polluted water can not occur.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described.
Figure 1 shows that the high large flux filter core that cuts dirty high sealing performance of the utility model, comprise filter course 1, inner support layer 2, outer support layer 3, upper end cover 4, bottom end cover 5 and sealing ring 6, inner support layer 2 is positioned at the inboard of filter course 1, outer support layer 3 is positioned at the outside of filter course 1, end cap is connected with the upper and lower end face of filter course 1 and inside and outside supporting layer respectively by hot melt up and down, the outer, bottom surface of described upper end cover is provided with a circle outer ring groove 7 that Open Side Down, and sealing ring 6 is positioned at the outer ring groove 7 of upper end cover 1; As shown in Figure 3, filter course 1 is the rete filter core of the folding mode loop collapsing of employing low ebb-peak-low ebb-peak-Gao Gu-peak-low ebb, that is take low ebb-peak-low ebb-peak-Gao Gu-peak-low ebb is a folding unit, connect and compose the rete filter core of the present embodiment by several identical folding unit hoop first places, high paddy arrives the distance at peak less than low ebb to the distance at peak, air line distance in the present embodiment between two low ebbs of arbitrary neighborhood equates, can certainly adopt form heterogeneous.Compare with existing folded membrane filter core shown in Figure 4, increased by about 30% filter area, increased simultaneously the water yield of 30%-50% at the inner ring film, the water yield that has reduced the Internal and external cycle film is poor, has solved the problem of bias current; The inner support layer is the silk screen of polypropylene material, and the outer support layer is the strengthening grid of polypropylene material.End cap is pure PP material up and down, and is discoid, and as shown in Figure 2, upper end cover 4 centers are provided with through hole 8; Upper end cover is provided with handle 9, and handle 9 is positioned at directly over the inner via hole 8; The bottom surface of described upper end cover 4 is provided with the stopper slot 11 of the spacing described filter course 1 of a circle, and the top ends of filter course 1 is located in the stopper slot 11; Sealing ring 6 is the O shape circle of silicon rubber material; The end face of described upper end cover is evenly equipped with 4 cylindrical slot 13.
After the large flux filter core of the utility model is installed in the filter, fix by securing member, securing member one end can be fixed filter core 1 by equally distributed 4 cylindrical slot 13 on the upper end cover 4, and the other end then is connected with filter.After the compression, sealing ring 6 produces normal deformation, and outer ring groove 7 can stop that O shape circle outwards continues torsional deformation, prevents from being deformed into outer ring groove 7 outer and produce poorly sealed.Sewage flows into from the through hole 8 of upper end cover 4 central authorities of this large flux filter core, by the grid on the inner support layer 2 flow through uniformly filter core around, through behind the filter course 1 of certain precision, impurity greater than precision is trapped within on the filter course 1, and filtered water then evenly flows out by the grid on the outer support layer 3.
