Technical field

The invention patent relates to technical field of filter cloth, and in particular to arrives chamber filter press, drum type vacuum filter etc. A kind of high-precision composite filtering cloth of solid-liquor separation filter plant.

Background technique

Currently, requirement of the solid-liquor separation filter plant to filter cloth performance and quality constantly improves, and it is common Filter cloth is that single woven fabric, looped fabric, non-woven fabrics, filter paper, woven fabric add the filtering cloth of non-woven fabrics mostly；Wherein woven mistake Filter cloth has the detachment of intensity height and filter cake good, and the reuse rate after cleaning is high or regenerability is high；Filter paper had It is high to filter precision, gap size is accurate, but intensity is low, and cannot reuse；And the strainability of non-woven fabrics is between woven filtering Cloth between filter paper, and have certain dust capaciting ability, will appear clogging after long-time service；Woven plus non-woven fabrics The filtering dust shake of composite filtering cloth fall and dust filtering effect is all preferable, and service life is also longer, but filtering accuracy and Filter effect also requires further improvement.

Summary of the invention

The purpose of the invention patent is that it is compound to provide a kind of high-precision for the above problem existing for existing filter cloth technology Filter cloth is achieved through the following technical solutions: a kind of high-precision composite filtering cloth, it is characterised in that: it includes filter paper 1, nonwoven Three layer of cloths of cloth 2, woven fabric 3；The filter paper 1 is the gap for consisting of fibers, and having certain specification size；The filtering Cloth 2 is the web being made of thermoplastic fibre；The woven fabric 3 is latticed, plain weave cloth, and plain weave cloth be by Several warp and weft weave, and wherein warp and weft are orthogonal；Filter paper 1, non-woven fabrics 2, three layers of woven fabric 3 mutually Between with equidistant, uniform point-like glue chalaza 3 or the group of strip gluing item 4 or point-like glue chalaza 3 and strip gluing item 4 Conjunction form is bonded, the spacing dimension of gluing point or adhesive tape: L 20,25,30,35,40,45,50,60,70,80, mm, W For 20,25,30,35,40,45,50,60,70,80 mm.

Beneficial effects of the present invention: a kind of high-precision composite filtering cloth, including filter paper 1, non-woven fabrics 2, three of woven fabric 3 Layer of cloth, filter paper 1, non-woven fabrics 2, three layers of woven fabric 3 between each other with equidistant uniform point-like glue chalaza 3, strip gluing item 4, Point-like glue chalaza 3 plus the combining form of strip gluing item 4 are bonded；This filter cloth has the characteristics that classified filtering, most of The larger impurity of volume can be woven filter cloth and filter, and the impurity for penetrating Woven filter cloth can retain one by non-woven fabrics Point, it is left minimum impurity and is further retained by filter paper, improve filtering accuracy and clarity, extends filter cloth service life, The characteristics of higher dedusting and filtering requirement can be met.
