The utility model also provides a kind of NACF tubular element with loss compensation device on the other hand, described filter core has filtration cavity, the top of described filtration cavity is provided with seal cavity, described seal cavity seals the part NACF filter course that filters cavity top completely, be used for when current enter the inside of filtering cavity, make the NACF filter course of its enclosure portion not participate in filtering.

Compared with prior art, one of the beneficial effects of the utility model are: according to NACF in tubular element after the on-line regeneration of certain number of times, can vertically produce loss and then form gap, by the seal cavity of setting up on the top of filtering cavity, make sealed part NACF filter course not participate in filtering, thereby when NACF filter course participation is in addition filtered and regenerate generation gap, can to gap, compensate timely, guarantee to filter the filter effect continuous and effective of cavity, and effectively extend the service life of NACF filter course, simultaneously a kind of NACF tubular element with loss compensation device provided by the utility model is simple in structure, be suitable for suitability for industrialized production, be easy to promote.

Accompanying drawing explanation

Fig. 1 is for the structural representation of an embodiment of the utility model is described;

In figure, 1 is that urceolus, 11 is that water inlet, 12 is that delivery port, 13 is that upper spacer, 14 is that lower clapboard, 2 is that NACF filter course, 21 is that Inner filter net, 22 is that outer leaching net, 23 is that active carbon, 3 is that filtration cavity, 4 is that seal cavity, 5 is sealing gasket.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further elaborated.

Shown in figure 1, an embodiment of the present utility model is a kind of NACF tubular element with loss compensation device, comprise urceolus 1, the inside of described urceolus 1 is provided with NACF filter course 2, described NACF filter course 2 isolates and filters cavity 3 in the inner chamber of urceolus 1, on described urceolus 1, be also provided with water inlet 11 and delivery port 12, described water inlet 11 is connected with filtration cavity 3, delivery port 12 is connected with the region except filtering cavity 3 in urceolus 1 inner chamber, yet what is more important, also need set up seal cavity 4 on the top of filtering cavity 3, described seal cavity 4 seals the part NACF filter course 2 that filters cavity 3 tops completely, for when current enter the inside of filtering cavity 3 by water inlet 11, make the NACF filter course 2 of its enclosure portion not participate in filtering.

The NACF tubular element with loss compensation device in above-described embodiment workflow is roughly as follows, current to be filtered are entered the inside of filtering cavity 3 by water inlet 11, by filtering cavity 3, by NACF filter course 2, enter the inner chamber of urceolus 1 again, current are in the process through NACF filter course 2, complete corresponding filtration, water after filtration is discharged from urceolus 1 by delivery port 12, and then complete once and to filter, in the actual use of filter core, aforesaid flow process can constantly circulate, and carries out continuously.

In the present embodiment, the effect of setting up seal cavity 4 on the top of filtering cavity 3 is that the gap that 2 regeneration produce to NACF filter course compensates, concrete principle is as follows, inventor finds through a large amount of experiments, NACF is subject to the impact of itself material, after having carried out repeatedly on-line regeneration in use, can produce loss along vertical direction, specifically referring to the direction shown in arrow A in Fig. 1, and then top starts to produce the gap that is enough to affect filter element filtering effect, and after adopting seal cavity 4 enclosure portion NACF filter courses 2, even if the NACF filter course 2 of this part becomes standby filtration resource, and this part is still interconnected with other NACF filter course 2, when gap produces, the NACF filter course 2 of spare part starts to be subject to the downward migration of impact of gravity, and then gap is filled, guarantee that NACF filter course 2 remains valid, extend the service life of filter core.

Shown in Fig. 1, in another embodiment of the present utility model, concrete structure about above-mentioned NACF filter course 2, inventor is with reference to prior art, think that its preferred structure is at least adopting the Inner filter net 21 of interlayer to form with outer leaching net 22, and between Inner filter net 21 and outer leaching net 22, be also filled with active carbon 23, and the above-mentioned NACF filter course 2 for compensate for clearance mainly refers to the active carbon 23 that the interlayer at Inner filter net 21 and outer leaching net 22 moves.

Still with reference to shown in figure 1, according to another embodiment of the present utility model, the preferred composition structure of above-mentioned urceolus 1 is for setting up respectively for forming the upper spacer 13 and lower clapboard 14 of its inner chamber with bottom at an upper portion thereof.

Further, be to guarantee the sealing of NACF filter course 2 and urceolus 1 inwall, preferably at top, bottom and the urceolus 1 of NACF filter course 2, between inwall, all set up up and down sealing gasket 5 again.

On above-mentioned basis, inventor has also done following improvement to the NACF tubular element with loss compensation device in above-described embodiment as shown in Figure 1, can be considered is one of embodiment of being more preferably of the utility model, be specially one urceolus 1 and the geometry of filtering cavity 3 are all set to circular cylindrical shape body, and urceolus 1 is preferably set to overlap with the axis of filtering cavity 3; It two has been set to two by the delivery port on urceolus 1 12, and is placed in respectively on corresponding position of filtering cavity 3 both sides.

Still with reference to shown in figure 1, in another embodiment of the present utility model, a kind of application a kind of NACF tubular element with loss compensation device more widely is also provided, identical with the above embodiments, described filter core also has the cavity 3 of filtration, the top of described filtration cavity 3 is provided with seal cavity 4, described seal cavity 4 seals the part NACF filter course 2 that filters cavity 3 tops completely, be used for when current enter the inside of filtering cavity 3, make the NACF filter course 2 of its enclosure portion not participate in filtering.

Except above-mentioned, also it should be noted that " embodiment ", " another embodiment " that spoken of in this manual, " embodiment " etc., refer to specific features, structure or the feature in conjunction with this embodiment, described and be included at least one embodiment that the application's generality describes.In description, a plurality of local appearance statement of the same race is not necessarily to refer to same embodiment.Furthermore, while describing a specific features, structure or feature in conjunction with arbitrary embodiment, what advocate is in conjunction with other embodiment, to realize this feature, structure or feature also to drop in scope of the present utility model.
