The coal washing plant treats the coal washing water and uses a press filter, but the filter cloth is cleaned with a high pressure water jet. The cycle is short again, and the filter cloth is blocked in a few hours! Do you have any good idea? Listen to the company's coal washing worker, said that before he washed the filter cloth in the coal washing plant, you can use for a long time, many days.
Most domestic press filters do very rough, resulting in cleaning cloth waste a lot of time and energy. A good filter cloth should be a combination of materials to choose yarn type and textile type. You can also blend the right and the wrong with different yarns. The mainstream of filter press filter cloth in foreign countries is this way.Of course, if you can't change the existing conditions, the filter cloth should be cleaned. It is better to flush the water from the reverse side, so that the particles won't go into the filter cloth gap.Point of view for reference.
Single filament yarn has the advantages of high filtering speed, large gap and small specific resistance. The short silk filter has the advantages of slow filtration rate, small gap and large specific resistance. Multifilament center.Textile style of plain weave, twill and satin fabric. Among them, the flat weave pore is small, the filtration speed is slow, the mud cake is not easy to fall off. Satin weave gap, smooth surface, easy to fall off the mud cake filter clogging.Your problem should be the choice of filter cloth is not appropriate.
I am just engaged in this field of work and I would like to talk with you.The service life of the filter cloth, or its life, is influenced by the fiber type of the textile filter cloth and the way the fiber is woven.Material fiber monofilament yarns, multifilament yarn, yarn short.
