Causes and Treatment Methods for Increased Loss of Filter Plate in Filter Press

A filter press is an important solid-liquid separation equipment widely used in the chemical industry, metallurgy, mining, and other fields. The filter plate is a key component of the filter press, and the increased loss of the filter plate during use may lead to a decline in equipment performance and affect production efficiency. This article mainly introduces the reasons for the increased loss of filter plate of filter press and the corresponding treatment methods.

Causes and Treatment Methods of Filter Plate Damage

Lack of feed or inappropriate solid particles

When the filter press lacks feed, the equipment itself is subjected to excessive force, which can easily lead to filter plate damage. In addition, if the feed contains inappropriate solid particles, these particles may cause additional impact and wear on the filter plate during operation, accelerating the loss of the filter plate.

Treatment method: By adjusting the volume ratio of the filter press filter plate, the pressure on the filter plate can be reduced, thereby reducing the loss rate. Note that the equipment parameters need to be reasonably adjusted according to the specific situation to ensure that the production efficiency is not affected; another method is to add a blind plate. Adding a blind plate to the filter plate can change the flow path of the medium, reduce the force of the filter press, and thus slow down the wear rate of the filter plate.

Material Leakage Caused by Unclean Filter Plate Cleaning

Material leakage caused by unclean filter plate cleaning is one of the reasons for the increased loss of filter plates in a filter press. Because the filter plate is not cleaned properly, the material may leak out during the filtration process, resulting in uneven pressure, which causes the filter plate to be unevenly washed and damages the surface of the filter plate. Material leakage may also cause small grooves on the surface of the filter plate, accelerating the wear and loss of the filter plate.

Treatment method: The operator should carefully clean the filter plate to ensure that the surface of the filter plate is clean and free of dirt so as to maintain the stable operation of the filter press and slow down the loss of the filter plate.

The Outlet is Blocked, or the Inlet and Outlet Valves are Closed

When the outlet is blocked by solids or the inlet and outlet valves are closed at startup, the pressure cannot be released smoothly, causing the filter plate to be subjected to uneven force for a long time, thereby damaging the filter plate. This situation will cause abnormal operation of the filter press and increase the maintenance cost of the equipment.

Handling method: To prevent this problem, the operator needs to regularly check the filter cloth, clean the drain, observe the outlet, and ensure that the corresponding valve is in the open state during operation to ensure good flow and pressure release, thereby reducing the adverse effects of the outlet on the filter plate. Through regular maintenance and reasonable operation, the loss of the filter plate caused by the outlet problem can be effectively reduced, and the service life of the filter press can be extended.

The Feed Port is Blocked Due to Excessive Sludge Thickness

When the sludge is too thick, it is easy to form a blockage at the feed port, causing the filter plate to be subjected to abnormal pressure and to be in a pressure state for a long time, thereby accelerating the loss of the filter plate. This situation may cause local wear on the filter plate, reduce equipment performance, and increase maintenance costs.

Treatment method: Clean in time, regularly remove the excessively thick sludge at the feed port, and keep the feed unobstructed. In addition, reasonable control of the sludge viscosity and the use of pretreatment methods, such as adding water or stirring, can help reduce the load on the feed port, reduce the loss rate of the filter plate, and extend the life of the equipment.

Conclusion

The increased loss of filter plates in filter presses may be affected by many factors. Starting from material selection, operating specifications, maintenance, and other aspects, the loss rate of filter plates can be effectively slowed down.
