Why does the automatic filter press with filter cloth discharge have a high discharge dryness?

Automatic filter press with filter cloth discharge can adjust the working pressure, usually by increasing the filter pressure to improve the discharge dryness. High working pressure can fully squeeze the filter cake during the pressing process and reduce its moisture content. By appropriately adjusting the pressure, operators can optimize according to the characteristics of different materials to achieve better filtration effects.
The choice of filter cloth also has a significant impact on the discharge dryness. Filter cloths of different materials and pore sizes have different filtration properties and are suitable for specific types of slurries. For example, polyester filter cloth is commonly used in the chemical and mining industries because of its chemical resistance and good strength. The filter cloth with smaller pore size can effectively prevent the penetration of fine particles and enhance the dryness of the filter cake. Choosing the appropriate filter cloth can not only improve the dryness of the discharge material, but also extend the service life of the equipment.
The design of the automatic unloading system is also an important factor affecting the dryness of the discharged material. During the unloading process, the reasonable design of the discharge angle and speed can reduce the residence time of the filter cake in the filter chamber and reduce the secondary leakage of liquid. In addition, the use of mechanical discharge or pneumatic discharge technology can ensure that the filter cake is discharged quickly and completely, thereby minimizing residual moisture.
Before entering the filter press, the pretreatment process of the slurry can also significantly improve the dryness of the discharged material. Through pretreatment, solid particles can be aggregated into clusters to form larger particle groups, which facilitates the subsequent filtration process. In addition, appropriate chemical additives can effectively improve the efficiency of solid-liquid separation and further improve the dryness of the filter cake.
