Connect, another in the relative second side of second filter layer 12 and described two walls is mutual
Set every ground；
When the filter element carries out filter operation, the deformable device 13 can be deformed into so that
The size of the facing portion of the filter bores of first filter layer 11 and second filter layer 12 point is less than institute
State the size of the facing portion point under filter element nature；When the filter element carries out recoil operation
When, the deformable device 13 can be deformed into so that first filter layer 11 and second filtering
The size of the facing portion point of the filter bores of layer 12 more than or equal under the filter element nature just
To the size of part.
According to filter element of the present invention, the first filter layer 11 and the second filter layer 12 are set to table
Spacing is disposed adjacent or sets with being laminated smaller between face, so that on the first filter layer 11
Filter bores can be compactly relative with the filter bores on the second filter layer 12, when deformable device 13 deforms
When can change the facing portion of filter bores on filter bores on the first filter layer 11 and the second filter layer 12
The size divided.That is, when fluid flows through the first filter layer 11 and the second filter layer 12, may not flow into
Between one filter layer 11 and the second filter layer 12, or flow into the first filter layer 11 and the second filter layer
Fluid between 12 is less or can not consider.And, even if the first filter layer 11 and the second mistake
There is certain interval between filtering layer 12, in actual applications, due to the first filter layer 11 and the second filtering
The both sides of the integral filter layer that layer 12 is constituted generally have pressure difference, hence in so that fluid is flowed primarily through
The filter bores in filter bores and the second filter layer 12 on first filter layer 11, without or only very
A few part is flowed between the first filter layer 11 and the second filter layer 12.
In addition, the filter layer 12 of the first filter layer 11 and second can be arranged as required into arbitrary shape,
Such as the first filter layer 11 and the second filter layer 12 could be arranged to plate, and fluid to be filtered is from the stacking
The side of plate flow into, the opposite side of the plate of the stacking is then the fluid after filtering.Certainly, this
It is other shapes and structure, sheet that one filter layer 11 and the second filter layer 12 can also be set as desired
Invention is not any limitation as to this.
Deformable device 13 in the present invention can also as needed using it is of the prior art any one
Structure, its function is that the deformable device 13 can occur corresponding deformation when by corresponding operating,
So as to change the chi of the facing portion point of the filter bores of the first filter layer 11 and the filter bores of the second filter layer 12
It is very little.Preferably, mainly there is dilatation in the deformable device, for example with telescope structure.
It should be noted that due to deformable device 13 can using in the prior art any one be applicable
Structure, therefore to the control of deformable device 13 can correspondingly in the prior art any one fit
Mode, for example, cause deformable device compression to occur or draws by using control devices such as applying external force
Deformation is stretched, or the deformable device can be realized automatically using methods such as automatically controlled or air pressure or hydraulic pressure
Control such that it is able to the which more accurately deflection to deformable device is controlled.
Described " size of the facing portion of filter bores point " can not be equal to the facing portion of filter bores herein
The area for dividing, because the gross area of the facing portion point of increase filter bores is actually to be conducive to improving filtering imitating
Rate, and this gross area has no directly with filter bores for the barrier effect of the solid particulate matter in fluid
Relation.Therefore, " size of the facing portion of filter bores point " should refer to certain of the facing portion point of filter bores
Size on one direction, refers preferably to the size on the size minimum direction at the most narrow place of facing portion point, i.e., right
For the shape of cross section of the facing portion point of filter bores, the size on size minimum direction determines institute's energy
By the size of the solid particle of the filter bores, therefore determine when filter element carries out different operating,
Size by the solid particle of filter bores is different.
When filter element carries out filter operation, the filter bores of the first filter layer 11 and the second filter layer 12
Facing portion point size it is smaller, therefore, it is possible to the solid particulate filters in fluid more than the size are fallen；
And when filter element carries out recoil operation, the filter bores of the first filter layer 11 and the second filter layer 12
The size increase of facing portion point, therefore backflushing fluid can wash out the facing portion office that is blocked in filter bores
Solid particle.
Also, what the present invention in practice required that protection is have a filtering in two filter layers being stacked
Layer is fixed, and another filter layer can be the filter layer movement of the relative fixation, i.e., this another
Filter layer is connected with deformable device 13.Therefore, the present invention is for the first filter layer 11 and the second filtering
The setting order of layer 12 is waited and not limited specifically, and those skilled in the art can be according to actual needs
And it is specifically chosen, for the ease of distinguishing and describing, the first filter layer 11 and deformable device are limited herein
13 connections.And, along its length two sides point of the first filter layer 11 and the second filter layer 12
It is not connected with two walls, the present invention does not limit first filter layer 11 which side along its length
It is connected with deformable device 13, i.e. one among the first filter layer 11 two sides along its length
It is connected among two walls by deformable device 13, is not any limitation as herein.In order to just
In description, the side that the first filter layer 11 is connected with deformable device 13 is defined as along length side herein
To second side.
Here " length direction " refers to two directions of wall of connection, for such as He of the first filter layer 11
Second filter layer 12 is formed as the implementation method of plate, is somebody's turn to do " length direction " and does not necessarily mean that first
The filter layer 12 of filter layer 11 and second size in this direction is more than on orthogonal other direction
Size.
For instance, it is preferred that the deformable device 13 could be arranged to be sent out when being acted on by external force
Change shape.For example, when filter element (does not carry out any operation to filter element in the raw
State) under, deformable device 13 is under a certain state (usually nature), and now first
The size of the facing portion of the filter bores of the filter bores of filter layer 11 and the second filter layer 12 point is a setting
Value, and when filter element is controlled make its carry out filter operation or recoil operation when, this is deformable
Device 13 deforms, for example, stretch or compress, so as to cause the filter bores and second of the first filter layer 11
The size of the facing portion of the filter bores of filter layer 12 point changes.
It should be noted that under the nature of above-mentioned deformable device 13 (i.e. at filter element
In the case of without mode of operation), the mistake of the filter bores of first filter layer 11 and the second filter layer 12
It is completely just right that filter opening can be preferably set to, when filter element carries out filter operation, deformable device
13 deform and cause the just right of the filter bores of the filter bores of the first filter layer 11 and the second filter layer 12
Partial size reduces.
The filter bores in filter bores and the second filter layer 12 for the first filter layer 11, it is preferable that should
The quantity of the filter bores of the filter bores of the first filter layer 11 and the second filter layer 12 is equal and size and position
Correspond respectively, i.e., when deformable device 13 can be adjusted under some state, now the first mistake
Whole filter bores of filtering layer 11 distinguish just right correspondingly with whole filter bores of the second filter layer 12.
Preferably, when deformable device 13 in the raw under (i.e. filter element be in without mode of operation
In the case of), whole filter bores one of whole filter bores of first filter layer 11 and the second filter layer 12
One accordingly distinguishes just right.
Filter element of the invention includes the first filter layer and the second filter layer, first filter layer and second
The size of the facing portion of the filter bores between filter layer point can be adjusted according to the need for different operating.It is logical
Above-mentioned technical proposal is crossed, filter element is enabled to when filter operation is carried out, reduces the just right of filter bores
Partial size, so that ensure the effect of filtering flow, and filter element increases when recoil operation is carried out
The size of the facing portion point of big filter bores, so as to improve the effect of recoil, effectively prevents filter bores from occurring stifled
Plug.
Preferably, in first filter layer 11 and second filter layer 12 is downstream filter
Layer, another is upstream filtering layer,
When the filter element carries out filter operation, fluid to be filtered is from the upstream filtering laminar flow to institute
Downstream filter layer is stated, when the filter element carries out recoil operation, backflushing fluid is from the downstream filter
Laminar flow to the upstream filtering layer,
The cross-sectional area of the filter bores of downstream filter layer is from close to the lateral of the upstream filtering layer
Opposite side gradually increases.
For the integral filter layer that the first filter layer 11 and the second filter layer 12 are constituted, fluid to be filtered
Opposite side is flowed to from the side of the overall filter layer, and for the first filter layer 11 and the second filter layer
For 12, the side of fluid to be filtered can be positioned close to.Therefore for the ease of description, draw here
Enter another with " the first filter layer " and " the second filter layer " mutually independent concept to make a distinction,
Filter layer i.e. with close fluid to be filtered in the first filter layer 11 and the second filter layer 12 is upstream filtering
Layer, the filter layer away from the fluid to be filtered is downstream filter layer.
From this angle, when we just can respectively carry out filter operation and recoil operation according to filter element
Fluid stream be always described.
When filter element carries out filter operation, fluid to be filtered is downstream filtered from upstream filtering laminar flow
Layer, now the size of the facing portion of the filter bores of the first filter layer 11 and the second filter layer 12 point is smaller,
Therefore, it is possible to the solid particulate filters in fluid more than the size of the facing portion point are fallen；And work as filter element
When carrying out recoil operation, backflushing fluid from downstream filter laminar flow upstream filter layer, now the first filter layer
11 and second filter layer 12 filter bores facing portion point size increase, therefore backflushing fluid can rush
Fall to be blocked in the fixed particle of the facing portion office of filter bores.
As can be seen here, in order to increase the performance of filter element, the He of the first filter layer 11 is on the one hand increased
The gross area of the facing portion of the filter bores of the second filter layer 12 point, therefore fluid to be filtered is improved by the
The flow of one filter layer 11 and the second filter layer 12, increases the filter efficiency of filter element；On the other hand,
The chi of filter element facing area of filter bores when filter operation and recoil operation is carried out rationally is set
It is very little.
And so distinguish upstream filtering layer and downstream filter layer still a further object is that, will be described under swim across
The cross-sectional area of the filter bores of filtering layer be set to from close to the upstream filtering layer a lateral opposite side by
It is cumulative big.So, when recoil operation is carried out, backflushing fluid flows through downstream filter layer and above swims across successively
Filtering layer, and when the backflushing fluid flows through the filter bores of downstream filter layer, due to the mistake of downstream filter layer
The cross-sectional area of filter opening is gradually reduced along the flow direction of backflushing fluid, therefore, it is possible to further improve recoil
The flow velocity of fluid, and the flow velocity of backflushing fluid is higher, its scouring force is stronger, and is blocked up in filter operation
Fill in the solid particle on filter element to be mainly blocked at the filter bores of upstream filtering layer, therefore improve
Repercussion effect.
