As the core element of filter press, industrial filter cloth plays a vital role in filtration. Using the filter principle of the filter press, the liquid and solid are separated under high pressure, and finally the filter cake is filtered out to achieve the filtering effect. The following are the precautions for the use of industrial filter cloth for filter press.
1. The filter cloth should be calendered and shaped to prevent the warp and weft threads from being loose.
2. When installing the filter cloth, the filter cloth spread on the filter plate should be flat and fixed to avoid damage to the filter cloth when the plate frame is compressed due to the folds of the filter cloth.
3. When the filter cake adheres to the filter cloth, its time should not be too long, otherwise, it will cause deformation and sagging of the filter cloth.
4. When unloading the filter cake, shovel the filter cake in the direction of the filter cloth.
5. For certain filter press industrial filter cloths, such as industrial filter cloths used in food, pharmaceutical, and other industries, it must be identified by relevant departments to ensure that it is harmless to humans. When in use, rinse with warm water to prevent dirt from being brought in.
6. After the filter cloth is used, if the cloth holes are blocked by scum and the cloth body becomes hard and affects the filtering speed, you can choose oxalic acid, caustic soda, alcohol, and other solutions according to various fiber properties to soak and clean the filter cloth. In this way, the cloth body can be softened and the hydrophobicity and air permeability of the filter cloth can be restored.
