Why does the plate and frame filter press appear to be fried?

As we all know, the plate and frame filter press is a large-scale machine that realizes the separation of solids and liquids. Due to the harsh working environment,Plate and frame filter pressAfter a long period of use, various problems will appear. Sometimes during the operation of the plate and frame filter press, due to the influence of various factors, the phenomenon of plate frying will occur. This phenomenon is very dangerous. Therefore, to avoid this phenomenon in time and effectively, we must understand Why does the phenomenon of frying the board occur? Next, Sudong Chemical Industry will answer it for you.


1. If the operating procedures are not followed, the valve is suddenly opened when the plate and frame filter press feeds, causing the filter plate to explode under excessive pressure;

2. When unloading, the feed port on the plate frame is not cleaned enough, the feed port is blocked, and the local pressure difference increases;

3. The plates and frames are not equipped in accordance with the required quantity, or partitions are not used to separate, causing the adjacent filter plates to be gradually exploded;

4. The feed resistance rises suddenly, and the driving force exceeds the bearing capacity of the filter plate;

5. The strength of the support beam of the filter plate is not enough, which causes uneven force on the plate frame after bending;

6. Mud enters on one side, and the force on the plane of the filter plate is uneven.


Now that we understand the reason for the plate-flashing phenomenon of the plate and frame filter press, we have to solve this problem in order to avoid such a problem next time. Therefore, we must strengthen the sense of responsibility and technical training of the operator of the plate and frame filter press, strictly control the valve opening speed, and frequently check the feed inlet status. If the quality of the mud feed is unqualified, necessary transformations are required, such as changing the beam support to a crane. Column support, change the hydraulic pressure on one side of the center cavity to hydraulic pressure on both sides or the mud inlet pipe to enter the mud at multiple points.


To sum up, if we are using the plate and frame filter press and there is a phenomenon of plate explosion, we must first check one by one according to the above reasons, and then prescribe the right medicine. In order to avoid the phenomenon of plate frying, we should always check the plate and frame filter press and pay close attention to any movement of the plate and frame filter press. If you have any questions about the maintenance of the plate and frame filter press and filter press, please consult the relevant technical personnel of Sudong Chemical.
