Long-term blockage of the filter cloth will not only cause the decline of filtration performance and increase the cost of filtration, but also affect the service life, premature aging and other consequences, for customers who can not filter and then take replacement measures, it is not recommended to reduce the blockage rate of the filter cloth as much as possible when filtering and separation, and it is recommended to disassemble and clean it in time when the filter cloth is seriously blocked.
The common causes of filter cloth clogging are as follows:
First, the quality of the filter cloth itself.
The yarn quality, structural structure, weaving process, post-treatment process, etc. of the filter cloth all affect the quality of the finished product, filtration efficiency, cleaning difficulty, service life, etc
Second, the selection of the problem.
The filtration accuracy of the filter cloth does not conform to the current working conditions, the filter residue is easy to remain in the pore size, and the long-term filtration leads to blockage
Third, the filter itself is a problem.
1. The main engine flushing system is faulty or blocked, and the filter cloth is blocked due to the inability to flush clean
2. The distance between the scraper and the surface of the filter cloth is too large, and a large amount of gypsum is accumulated on the surface of the filter cloth, which is difficult to clean, and the surface of the filter cloth is easy to scale
3. Host sealing: poor sealing of the belt filter will lead to low vacuum of the whole system, which will affect the filtration effect and cause the filter cloth to be blocked
How to clean a clogged filter cloth:
1.When cleaning the filter cloth used for alkaline filter media, it should be soaked in weak acid;
2.When cleaning the filter cloth used for acidic filter media, it should be soaked in a weak alkali solution.
The soaking time is 1-2 days. Then wash.
