Description

Three line composite filtering cloths and the filter bag taking three line composite filtering cloths as main body thereof

Technical field

The utility model relates to a kind of nonwoven filter cloth, especially, solid the utility model relate to mining that mineral resources industry improves resource recycling rate with ore dressing, altogether, the sorting extraction of associated minerals, industrial fluids liquid/separate and material purification or reclaim required filter cloth.

Background technology

At present, industrial woven and nonwoven textile fabric filter cloth is widely used in mining, ore dressing, the dehydration of mineral resources industry; Gu in the filter progress of the sorting extraction of associated minerals altogether,, coal washing, oil plant PETROLEUM PROCESSING, industrial fluids liquid/separation, material purification or recovery.And Woven filter cloth used is mostly the conventional Woven filter cloth of being made up of chemical fibre or natural fiber on industrial filter machine, also there is a small amount of nonwoven acupuncture filter cloth of being made by chemical fibre or natural fiber.

The filtering material of ideal structure must have following condition: (1) porosity is high; (2) filter efficiency is high; (3) filtration resistance is little, and the pressure loss is low; (4) there is enough intensity, dimensionally stable, wearability is good.But, because woven chemical fibre filter cloth or natural fiber filter cloth are in its manufacture process and technique, what adopt is the staggered woven mode of warp thread and weft yarn, the porosity control of its filtration is to lean on the fiber number of warp thread and weft yarn and warp thread and the staggered density of weft yarn to realize, and, the cross-point of warp thread and weft yarn has formed comprehensive equally distributed intertwined point or gap on filter cloth surface, make to be filtered composition granule very easily in filtration operation process frequently in these intertwined points or gap assemble gradually and accumulate, filter cloth hole is diminished, be difficult for cake discharge, filter cloth stops up, filtered fluid input system pump pressure increases, filter efficiency reduces, the filter cloth replacement cycle shortens, filter cloth minimizing in service life, cause filter cloth user side production efficiency to decline and production cost rising.Wherein, the obstruction of filter cloth is a main cause that causes filter cloth permeability rate not high.Further, the nonwoven acupuncture filter cloth of being made up of chemical fibre or natural fiber, due to the three-dimensional structure advantage of itself, in filtration work, there is filter efficiency very high, the very little advantage of pressure reduction of filtration system, still, the intensity of this nonwoven filter cloth is extremely low, and service life is very short.And up to now, Gu still fail to propose good solution in the liquid/separation of industrial fluids with filtration art.
