Industrial filter cloth is a filter medium woven from natural fibers and synthetic fibers, mainly used for solid-liquid separation and industrial dust removal.
Preparation of industrial filter cloth
Synthetic fibers mainly include polypropylene, polyester, nylon, vinylon, etc. Among them, polyester and polypropylene are the most commonly used, mainly solid-liquid separation. The general industrial filter cloth also includes various metal materials such as stainless steel wire, nickel wire and brass. wire.
material:
Polyester, polypropylene, nylon, vinylon, aramid, glass, cotton, fiberglass, basalt fiber.
Weaving method:
Made of plain weave and twill weave and satin weave, non-woven needle-punched.
Features and performance:
High precision, strong load, acid, alkali, temperature and wear resistance, with special filtration performance.
specification:
5 mesh – 2300 mesh, air permeability 10-21m / s.Industrial filter cloth use
Used for solid-liquid separation, gas-solid separation; gas-solid separation application areas of iron and steel plants, steel mills, ferroalloy plants, refractory plants, foundries, power plants and other flue gas treatment dust removal system. Flue gas filtration of waste incinerators, coal-fired boilers, fluidized bed boilers, etc.
Asphalt concrete mixing, building materials, cement ceramics, lime, gypsum and other production sites. Smelting flue gas filtration of aluminum electrolysis, lead, tin, zinc, copper and other rare metals, fine material recovery, liquid and solid separation. Liquid-solid separation and fine material recovery in the fields of chemical industry, coke, carbon black, dyes, pharmaceuticals and plastics. Dust management and purification collection for mining, food processing, flour, electronics, wood processing, etc. Solid-liquid separation application field

Coatings, paints and inks: latex paints, paint materials and solvent filtration, printing inks, printing inks and additive filtration.Industrial filter cloth precautions
Bag type dust collector
1 filter cloth should not be too loose or too tight, too loose and easy to accumulate dust, too tight and easy to pull.
2 New and old filter bags should not be mixed to avoid damage to the equipment and normal operation.
3 Replace the filter bag, first blow it with compressed air, and then check for holes. After repairing the holes, leave them for replacement. If it is dusty filter bag, rinse with water, dry and leave to be replaced.
Wooden earphones
1 When installing the fungus filter bag, do not hang the filter bag with a hard object to avoid damage to the fiber, which causes the filter bag to pierce in a short period of time.
2 should stop at the appropriate thickness of the filter cake, and then work after unloading the cake, which can extend the life of the filter bag.
3 When changing the filter bag, you can not use the hard object to directly pull the filter bag to pull down, and apply the force to pull up the auxiliary belt sewn on the filter bag.
4 When unloading the filter cake, the unloading cake should be kept parallel with the filter cloth as much as possible to prevent damage to the filter bag.
Filter press
1 When installing the filter cloth, ensure that the filter cloth on the upper part of the board frame is flat and fixed to avoid damage to the filter cloth when the board frame is pressed due to the discount of the filter cloth.
2 The time for the filter cake to adhere to the filter cloth should not be too long. If the filter is too long, it will cause deformation and sagging of the filter cloth.
3 When unloading the filter cake, shovel the cake along the direction of the filter cloth.
Belt filter
1 The required filter cloth length (including joint length) should be measured correctly.
2 When sewing, ensure that the wefts at both ends are coincident or parallel to prevent the filter cloth from running off during operation.
3 interface should pay attention to the direction of operation, so as to avoid the blade blocking the filter cloth interface and damage the filter cloth or hinder the filter cloth.
Vertical plate machine (vertical disc machine)
1 The filter cloth selected should not be too thick, too thick is not conducive to the sewing machine when the filter is installed.
2 The surface of the selected filter cloth should not be too smooth, too smooth and not suitable for the formation of filter cake, which affects production efficiency.
Labor machine (vertical filter machine)
1 requires the filter cloth to have a certain thickness and strong tensile strength.
2 joints should ensure that the wefts at both ends are coincident or parallel, in case the filter cloth runs off during operation.
3 interface should pay attention to the direction of operation, so as to avoid the blade blocking the filter cloth interface and damage the filter cloth or hinder the filter cloth.
