If the filter press of the sludge dewatering equipment exhibits the phenomenon of material running from the filter plate of the filter press during operation, it will greatly affect the filtering effect of the sludge. However, if you check carefully, you will find that the cause of the running material is easy to investigate and deal with. It is not difficult to get up. The following editor will analyze the reasons and treatment methods of the filter plate of the filter press.
1. The flow rate of the feed pump is too large. If the flow rate of the feed pump exceeds the conventional capacity of the filter press and the feed flow rate is too large, the filter plate of the filter press may run out of material. At this time, it is only necessary to adjust the valve of the feed pump and install the backflow. The problem can be easily solved by opening the return valve.
2. The feed pressure is too large. Although the higher the pressure, the filter press can filter out the moisture of the sludge to a greater extent, but at the same time, there will be different degrees of back pressure, forming the filter plate of the filter press. In the sludge treatment, the feed pressure should be controlled under the additional pressure.
3. The arrangement of the filter plates is irregular. For the filter press, the regular arrangement of the filter plates is also very important. If the dislocation exceeds 5mm, the filter plate of the filter press will run out during the filter press.
4. Insufficient compression force When using the filter press, pay attention to the pressure strength of the applicable filter plate. Insufficient pressure will also cause the filter plate of the filter press to run out of material. If the compression force is low, adjust the pressure slowly to the accustomed range, but it should not be too much. , If the extra pressure is exceeded, the filter press will be overloaded.
5. The filter cloth is not flat If the filter cloth is not flat, the filter plate will not be pressed tightly, so when running the material, check whether the filter cloth is wrinkled, and if it is flattened in time.
6. There are impurities on the sealing surface of the filter plate. Before each sludge treatment, the cleanliness of the filter plate should be checked to ensure that the sealing surface is clean.
