Filter plate is an important part of the filter press, the price is more expensive, and because of its heavy weight, it is also extremely inconvenient to replace. Due to improper use and maintenance, filter plate damage often occurs in production, which may cause material running between filter plates, and serious consequences such as filter plate deformation, sealing surface damage, diaphragm damage and so on.
The impact of regular production, but also caused heavy economic losses. Next, Donglong will take you to analyze the causes of the damage to the filter plate of the filter press and how to deal with it. ​​​​​​​
1. Damage caused by pressure imbalance on both sides of the filter plate: when the filter press is working, the filter plate needs to bear the pressure of 0.6MPa.When working normally, the pressure on both sides of the filter plate is balanced, and the pressure rises gradually from small to large to the outlet pressure of the feed pump. When the work is abnormal (may be due to blockage of the water outlet), the pressure in the filter cavity will quickly rise to the outlet pressure of the feed pump, while the pressure in the filter cavity on the other side of the filter plate (which may be normal or the feed is not smooth) rises gradually, so that a pressure difference is formed on both sides of the filter plate, resulting in deformation in the middle of the filter plate, thus damaging the filter plate. Therefore, during the feeding period of the filter press, the effluent of the outlet should be carefully observed. if there is no outlet, it means that the outlet may be blocked, stop the feed pump immediately, open the compression plate and the filter plate where the outlet is blocked or the feed is not smooth, check and repair, and then resume the feed pressure filtration after the failure.
