Area of section S1Unit be mm2(square millimeter).
Further, the arc length of the internal ring wall 611 of the lamination body 61 between adjacent bending unit 62 is W two-by-two2, the
The height of one divider wall 621 and the height of the second divider wall 622 are H, export 64 area of section S2Meet equation below：S2
=W2×H.Wherein, arc length W2Unit with height H is mm (millimeter), area of section S2Unit be mm2(square millimeter).
As shown in Figure 2 and Figure 5, in an embodiment of the invention, the lower surface of lamination body 61 can be provided with more
Individual bulge loop 67, those bulge loops 67 are arranged concentrically, and the center of those bulge loops 67 and the center of lamination body 61 are arranged concentrically, at this
In embodiment, the lower surface of lamination body 61 is provided with two concentric bulge loops 67, certainly, in other implementations, lamination
The lower surface of body 61 can also be provided with multiple concentric bulge loops 67, and this is not restricted.
As shown in figure 1, in the state of multiple filtering 6 assemblings stacked on top of one another of lamination, the meeting of bulge loop 67 of upper level filter lamination 6
It is pressed on the bending unit 62 of lower floor's filtering lamination 6, in actual applications, typically has multi-disc filtering lamination 6 and overlay one
Rise, form the cylindric filtration with multiple filtration lamination 6.In operation, can according to the size of water-carrying capacity to be filtered,
To adjust the quantity of filtering lamination 6.
In the present invention, the height of those bulge loops 67 is identical with the width of flow-guiding channel 65, is arranged such, when two panels filters
When the mounted on top of lamination 6 is set, the upper surface of bending unit 62 of lamination 6 is filtered to the lamination body of upper level filter lamination 6 by lower floor
Gap between 61 lower surfaces is determined by the height of bulge loop 67, and the height of bulge loop 67 and the width phase of flow-guiding channel 65
Together, then it ensure that above-mentioned gap is consistent with the filtering accuracy of flow-guiding channel 65.

Complementarity, i.e., when single filtering lamination 6 blocks, water can be continued to complete by the through hole 614 of first through hole 613 and second
Filter.
Embodiment two
The present invention also provides a kind of laminated filter of the filtering lamination 6 comprising embodiment one, and described filtering is folded
Structure, operation principle and the beneficial effect of piece 6 are identical with embodiment one, will not be repeated here.
As shown in figure 8, a kind of laminated filter for including above-mentioned filtering lamination 6, including：Housing 1, be connected with thereon into
Waterpipe 2, outlet conduit 3 and Backwash pipeline 4；Filter core support 5, it is arranged in the housing 1, is arranged on filter core support 5
There are multiple filtering laminations 6 stacked on top of one another.Specifically, it is respectively equipped with valve in inlet channel 2, outlet conduit 3 and Backwash pipeline 4
Door, those valves are used to open or close inlet channel 2, outlet conduit 3 and Backwash pipeline 4.
In the present embodiment, the laminated filter includes three sets of filter elements, that is, the first filter element 7, the second mistake
The filter element 9 of unit 8 and the 3rd is filtered, wherein, the first filter element 7 is provided with the first inlet valve 21 and the first back flush valves
41, the first inlet valve 21 the first filter element 7 of control is turned on and off with inlet channel 2, and the first back flush valves 41 are controlled
Made being turned on and off for the first filter unit 7 and Backwash pipeline 4；Second filter element 8 is provided with the second inlet valve 22 and the
Two back flush valves 42, the second inlet valve 22 the second filter element 8 of control are turned on and off with inlet channel 2, and second is anti-
The second filter element 8 of control of flushing valve 42 is turned on and off with Backwash pipeline 4；3rd filter element 9 enters provided with the 3rd
The back flush valves 43 of penstock 23 and the 3rd, the unlatching of the filter element 9 of the 3rd inlet valve 23 control the 3rd and inlet channel 2 or
Close, the 3rd back flush valves 43 the 3rd filter element 9 of control is turned on and off with Backwash pipeline 4.This three sets filterings are single
It is first in parallel, what inlet channel 2 can form with the external annulus 612 of multiple filtering laminations 6 and housing 1 in three sets of filter elements respectively
Annular space is connected, and outlet conduit 3 can be common with the internal ring wall 611 of multiple filtering laminations 6 in three sets of filter elements respectively
The cylindrical space of composition is connected, and Backwash pipeline 4 connects with blow-off line 40.The filtration operation of above-mentioned each filter element
It will not influence each other.
When the laminated filter carries out the operation of normal filtration water, the first inlet valve 21, the second water intaking valve are opened
The inlet valve 23 of door 22 and the 3rd, water to be filtered enter in housing 1 from inlet channel 2, pass through the first inlet valve 21, second
The inlet valve 23 of inlet valve 22 and the 3rd, respectively enter the external annulus 612 of multiple filtering laminations 6 and housing of three sets of filter elements
In the annular space of 1 composition, the periphery wall filtering of the filtering lamination 6 through multiple stackings enters the filtering lamination 6 of multiple stackings
Inside, filtering is completed, concentrate from outlet conduit 3 and flow out from the water after three filter elements filterings.Due to each filter element
Set independently of each other, wherein some filter element breaks down, and does not interfere with the work of other filter elements.
When carrying out backsurging operation to some filter element of the laminated filter, other filter elements do as usual work
Make, for example, as shown in figure 8, when carrying out backsurging operation to the 3rd filter element 9, the first inlet valve 21 and the second water intaking valve
Door 22 is opened, and the first back flush valves 41 and the second back flush valves 42 are closed, meanwhile, the 3rd inlet valve 23 is closed, and the 3rd
Back flush valves 43 are opened, and the clear water now filtered through the first filter element 7 and the second filter element 8 can flow from outlet conduit 3
Go out, while understand the inside that some clear water is further separated into the 3rd filter element 9 filtering lamination 6, in certain clear water pressure
Under momentum effect, opened above and below the meeting of filtering lamination 6 of multiple stackings and spaced apart, so as to remain in each filtering lamination
Impurity particle on 6 multiple bending units 62 can be flushed away under the hydraulic pressure effect of clear water, and sewage is from the 3rd back flush valves
43 inflow blow-off lines 40 are discharged.When needing to backwash the first filter element 7 and the second filter element 8, process with
Said process is similar, will not be repeated here.The laminated filter of the present invention, when carrying out backsurging operation, filtration operation is not
Interruption, it is ensured that the interruption supply of clear water.In real work, the quantity of filter element is not limited to three sets, particular number root
Depending on being actually needed.
The present invention laminated filter, the filtering lamination 6 in it is simple in construction, good filtration effect and with backwash work(
Can, the laminated filter can accurately be filtered to current, can improve the effect of water filtration, in addition, when being backwashed,
The filtering lamination 6 of multiple stackings can be separated from each other, and the clear water sent by Backwash pipeline 4 will can each filter rapidly folded
Impurity particle on piece 6 is rinsed well, and its backwash effect is very good.
Several embodiments of the present invention are the foregoing is only, those skilled in the art is according to application documents disclosure
Various changes or modifications can be carried out without departing from the spirit and scope of the present invention to the embodiment of the present invention.
