Technical field
The present invention relates to a kind of filter cloth structure being used in dust arrester etc..
Background technology
In the past, following filter cloth was widely used as the filter cloth being used in dust arrester etc., i.e. will be constituted by weaving cotton cloth by stacking
Base cloth layer and be at least incorporated into the filter course being made up of non-woven fabrics of filtering surface side of this base cloth layer and the filter cloth coiled material constituted
Be formed as tubular, and make dust laden air by filter cloth thus filter from the rear side of the lateral filter cloth of the filtering surface of this filter cloth,
Further, make counter-current flow from lateral filtering surface side, the back side of filter cloth by filter cloth thus brush lightly the dust trapped.(such as, ginseng
Examine patent documentation 1).
But, owing to this filter cloth directly uses the base cloth layer constituted by weaving cotton cloth and the filter course stacking being made up of non-woven fabrics
And the filter cloth coiled material constituted, and the both sides of the edge extended along its length of this filter cloth coiled material are engaged with each other and are formed as cylinder
Shape, therefore, although weaving cotton cloth of base cloth layer is formed by braiding warp thread and weft yarn, but the direction of its warp thread generally and is formed
Cylinder axis direction for the filter cloth of tubular is parallel, and the direction of weft yarn is the most orthogonal with cylinder axis direction.
Further, the dust arrester of this filter cloth is installed by operation, makes dust laden air from the filtering surface effluent of filter cloth to filter cloth
Rear side so that dust is trapped on filter cloth, but, if the dust being captured by the operation of dust arrester be attached to filter
The filtering surface side of cloth, then the filter course of filter cloth can produce blocking, can cause the increase of the pressure loss.
At this time, it may be necessary to brush lightly to the dust of the filter course being attached to filter cloth, filter cloth is made to return to the pressure loss relatively low
State.To this end, the dust arrester possessing following function can be utilized, this function is as follows: by making the counter-current flow back of the body from filter cloth
Lateral filtering surface side, face is by filter cloth thus carries out the regeneration (such as, referenced patent document 2) of filter cloth.
But, conventional filter cloth is parallel and weft yarn with the cylinder axis direction of the filter cloth being formed as tubular due to the direction of warp thread
Direction is orthogonal with cylinder axis direction, therefore, even if making filter cloth vibration or flexible, due on the direction, face (cylinder circumferential direction) of filter course
Displacement is limited by weft yarn, does not the most play and makes filter course energetically in direction, face (cylinder circumferential direction) upper flexible effect.I.e., not
Can become and make filter cloth energetically to the structure of filtering surface side (side, barrel dliameter direction) displacement.
Further, in the case of this filter cloth is used in dust arrester, although can brush lightly to fall to being caught by counter-current flow
Combine in the dust of the filtering surface of filter cloth, but, make filter course stretch on direction, face energetically as mentioned above due to do not play
Effect, so being difficult to effectively brush lightly the dust of the inside falling to entering into filter cloth.
Further, in above-mentioned dust arrester, brush lightly efficiency, therefore due to cannot improve the dust of the inside entering into filter cloth
The average pressure loss of filter cloth becomes larger, and causes needing the pressure strengthening counter-current flow or increase to brush lightly number of times etc., thus nothing
Method realizes energy-saving, cannot improve the life-span of filter cloth.
On the other hand, as solve the problems referred to above scheme, such as it is shown in figure 9, propose before applicant in this case as
The filter cloth F of lower structure, this structure is as follows: is rolled into helical form by being made into weaving cotton cloth of the base cloth layer 20 of banding and forms the laggard of tubular
Row is sewed up so that constitute the side in the warp thread weaved cotton cloth and the weft yarn of base cloth layer 20 and the opposing party relative to the filter being formed as tubular
The cylinder axis direction X of cloth F and cylinder circumferential direction Y tilt (with reference to profit document 3).

In filter cloth F described in this patent documentation 3, filter course displacement in direction, face (cylinder circumferential direction) will not be subject to
Warp thread and the side in weft yarn or the restriction of the opposing party, its result, the filter cloth F displacement to filtering surface side (side, barrel dliameter direction) is not subject to
Limit (that is, allowing a certain degree of displacement).Now, along with filter cloth F is in the displacement of filtering surface side, the base cloth layer of filter cloth F
Warp thread can change significantly with the intersecting angle of weft yarn.
By the change of this warp thread Yu the intersecting angle of weft yarn, be at least incorporated into base cloth layer filtering surface side by non-woven fabrics
Flexible on direction, face of filter course constituted becomes bigger.
Further, the non-woven fabrics formed owing to filter course is mutually wound around by microfibre is constituted, and therefore filter course is in face side
Flexible meeting upwards makes the shape in the gap between this microfibre change on whole.
Therefore, it is possible to suppression is trapped in the dust condensing of the filter course being made up of non-woven fabrics, and can moderately disperse
And pulverize this dust such that it is able to make dust come off from filter course easily.
Therefore, have can improve dust brush lightly efficiency, be capable of because of the average pressure of filter cloth F loss reduction and
The energy-saving that brings, the advantage in the life-span that can improve filter cloth.
But, the base cloth layer 20 of this filter cloth F described in patent documentation 3 is by being rolled into spiral by being made into weaving cotton cloth of banding
Shape and carry out sewing up and constituting after forming tubular, therefore this filter cloth F is being installed on retainer the filter carrying out using
In cloth structure, owing to the most strictly limiting the measure of the length on the cylinder axis direction X of filter cloth F, filter cloth F the most during use
Because of own wt etc. to cylinder axis direction X stretching thus can be sagging from the lower end of retainer.
Further, in the part that this is sagging, if processing the most especially, then the tension force of filter cloth F can disappear, and can reduce and be captured
Dust brush lightly efficiency, the filtering function of filter cloth F also decreases, and stress is concentrated in this sagging part thus holds
Easily damage, be an impediment to energy-saving and the raising in filter cloth F life-span of filter cloth F.

Pulse jet mode).
That is, in the cylinder of filter cloth F, flow to the high pressure air flow as counter-current flow H cylinder make to be formed as the filter cloth of tubular
F is towards filtering surface side (that is, diameter becomes big side) displacement significantly, thus, as shown in Fig. 7 (b), warp thread 20a be formed as
The cylinder axis direction X institute of the filter cloth F of tubular becomes big in angle beta.
Further, such as, owing to repeatedly spraying pressure-air across intervals, therefore filter cloth F is repeatedly to filtration
Displacement between state and the original state of side, face displacement, the most described angle α and angle beta change off and on, and filter course 21 exists
Stretching on direction, face produces the most off and on, therefore, it is possible to suppression is trapped in the dust condensing of filter course 21, and can appropriateness
Ground disperses and pulverizes this dust.
It addition, in said structure, the filter cloth F displacement to filtering surface side is converted into filter cloth F contraction on cylinder axis direction X
Power.
Therefore, it is possible to the shrinkage direction making the tension force on the cylinder axis direction X of filter cloth F expand outward with filter cloth F and producing
Power be balanced, thus flexible on cylinder axis direction X of the filter cloth F displacement to filtering surface side and filter cloth F shows as well
Vibrational state, and the change of the intersecting angle of warp thread 20a and weft yarn 20b is also with vibrational state performance, it is thus possible to further
Suppression is trapped in the dust condensing of filter course 21, and can moderately disperse and pulverize this dust.
