Description
Technical field
The present invention relates to a kind of knitted fabric filter cloth and its manufacturing methods, are related to textile technology field；More particularly to industry is used
Industrial filter cloth technical field in textile；More particularly to knitted fabric filter cloth technical field used on plate and frame filter press.
Background technology
Currently, industry is widely used in ore dressing dehydration, coal washing, the refining of mineral resource industry with textile fiber filter medium
In oily factory's oil dewaxing, industrial fluids liquid/solid separation, material purification or the filter progress of recycling.And it is used on plate and frame filter press
Filter medium be mostly the Woven filter cloth made of chemical fibre or natural fiber.
But since chemical fibre or natural fiber woven filter cloth are in its manufacturing process and technique, using warp thread and latitude
Yarn interlocks woven mode, and the porosity control of filtering is the close of fiber number and warp thread by warp thread and weft yarn and weft yarns
Degree and mode are realized.Moreover, the intertexture of warp thread and weft yarn or to be staggeredly formed by filtering hole or density fixed once finished product
Type and input are applied, and filtering hole or density just can not adjust and change.And with its filter hole of the increase of filter cycle
Gap or density can only be smaller and smaller；The comprehensive equally distributed longitude and latitude intertwined point or gap that Woven filter cloth surface is formed so that
Easily gradually assembled and accumulated in these intertwined points or gap during frequent filtration operation by filtering composition granule so that mistake
Filter cloth hole becomes smaller, is not easy cake discharge, filter cloth blocks, filtered fluid input system pump pressure increases, filter efficiency reduces, filter cloth is replaced
The period shortens, filter cloth service life is reduced, the filter cloth number that even if easy cleaning, filter cloth are not reused after cleaning is reduced,
Cause filter cloth user side's production efficiency to decline with production cost to rise.
Invention content
Based on above-mentioned technical problem, the present invention provides a kind of knitted fabric filter cloth and its manufacturing methods.
The invention is realized by the following technical scheme：It is former used by a kind of described knitted fabric filter cloth and its manufacturing method
Material is conventional or well known commercially available textile fabric；The line of the filter cloth, which is knitted, is organized as conventional one be knitted in institutional framework
Kind.Knitted fabric is by yarn sequential forming into coil, mutually goes here and there set by coil and forms fabric.The mode that yarn forms coil can
Transversely or longitudinally to be woven, laterally braiding is known as weft-knitted fabric, longitudinal knitted to be known as knitted fabric.Compared to woven group
Structure is knitted, a distinguishing feature of knitting technology weave structure, which is fabric itself, to be extended in all directions, and elasticity is good, due to knitted fabric
It is to be formed by poroid coil, thus there is larger permeability, it is then larger filter hole which, which is embodied on filter cloth,
Porosity.Moreover, the fixation in the knitted fabric filter cloth surrounding uses three gear adjusting positions with button hole, between each gear
Adjustable range is set as 5cm.Filter cloth is fixed using the first gear when initial use, it can be by fixation after one section of filtering operation
It is adjusted to the second gear with button, filter cloth can be stretched out to the distance of a gear in peripheral direction at this time, i.e.,：5cm.Its
Practical function be it is stretched after filter cloth filtering porosity correspondingly equivalent increase.The principle and effect of third gear with
Second gear is similarly.So, knitted fabric filter cloth of the present invention has compared to the Woven filter cloth being commonly used
The effect that clear reliable filtering porosity increase is adjusted.

Specific implementation mode
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings.Below with reference to
The embodiment of attached drawing description is exemplary, and is only used for explaining the present invention, and is not construed as limiting the claims.
Specific implementation mode
The embodiment of the present invention is described below in detail, the examples of the embodiments are shown in Figure 1.The knitting
Raw material used in filter cloth is 6 monfil of nylon；It is weft organization's structure that line, which knits structure,；The fixed of the filter cloth surrounding is used
Button hole uses three gear adjusting positions, and the adjustable range between each gear is set as 5cm.
After the present invention, examination experiment is carried out, through certification test, has obtained expected good result.
Its specific process step is as follows：
(1) 100% 6 monfil of nylon, fiber number are chosen：120D, it is spare as the knitting yarn of knitted fabric filter cloth.
(2) above-mentioned spare knitting yarn is subjected to winder processing, cylinder yarn is made, it is spare.
(3) processing, and 2 strands of thread number latitude will be carried out and twisted on doubler twister through above-mentioned warp thread, the twist is 30 twirls/10cm,
Twist direction is twisted for Z, spare.
(4) processing, and 2 strands of thread number latitude will be carried out and twisted on doubler twister through above-mentioned weft yarn, the twist is 30 twirls/10cm,
Twist direction is twisted for Z, spare.
(5) warp beam is made by warping machine in above-mentioned spare warp thread, in case the warp thread as filter cloth.
(6) above-mentioned spare weft yarn is subjected to winder processing, cylinder yarn is made, in case the weft yarn as filter cloth.
(7) by machine, denting in above-mentioned warp beam：Porter is 62.99/10cm, and denting 16 enters/reed, the heald frames of page 8, gait for
Fly to wear.
(8) machine in above-mentioned cylinder yarn is used as weft yarn.
(9) then, it is filtered the weaving of cloth.
(10) by machine under the filter cloth being made into, severing and sewing are carried out.
(11) severing and sewing after, filter cloth surrounding for fixing buckle frame position carry out three gears punching and
Nail catcher.
(12) product inspection and packaging.
Filter cloth is when upper machine is installed and used for the first time, using special tied rope to the first of filter cloth surrounding button hole for fixing
Gear is filtered the fixation of cloth.Wait for filter press run to some cycles filter cloth occur blocking or system pump pressure be increased to it is certain
When degree, then the fixation of cloth is filtered with special tied rope in the second gear of filter cloth surrounding button hole for fixing.In this way
One, since the distance between each gear is 5cm.Therefore, often increase a fixed gear when, just from four direction incited somebody to action
Filter cloth has respectively stretched 5cm outward.That is by the longitude and latitude intertexture density of filter cloth or filtering porosity from four direction to
Respectively increase 5cm outside.Third gear is similarly.Warp as a result of 6 filament fiber of nylon with abundant elasticity as filter cloth
Latitude raw material, the stretching for carrying out three gears do not interfere with the institutional framework of filter cloth itself and corresponding strength.This measure it is direct
It is to effectively increase the filtering hole and filter efficiency of filter cloth with specific effect.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the present invention in any form.It is all
The those of ordinary skill of the industry, can be shown in by specification attached drawing and described above, swimmingly implements the present invention.But it is all
Those skilled in the art are not departing from technical solution of the present invention range, when using disclosed above technology contents
And the equivalent variations for a little variation, modification and evolution made, it is the equivalent embodiment of the present invention；Meanwhile it is all according to this hair
Bright substantial technological still falls within the present invention to the variation, modification and evolution etc. of any equivalent variations made by above example
Technical solution range.
