As an important filtration equipment, filter press has been widely used in many industries. However, sometimes the filter cake is not dry enough, which not only affects the filtration effect, but can also have a negative impact on production. This article will analyze the reasons why the filter cake of the filter press is not dry enough, in order to help users better understand and solve this problem.
First, the quality of the filter cloth is not up to standard.
The filter cloth is one of the important components of the filter press, and its quality directly affects the filtration effect. If the quality of the filter cloth used is not up to standard, the filtered filter cake will have a high moisture content and will not be dry enough. Therefore, when choosing a filter cloth, you should choose products with reliable quality and good brand reputation, and at the same time, you should replace the filter cloth regularly to avoid affecting the filtration effect due to the aging of the filter cloth.
2. Improper feeding pressure.
In the process of filter pressing, the amount of feed pressure directly affects the dryness of the filter cake. If the feed pressure is too large, the moisture in the material will be forced to be discharged through the filter cloth, so that the water content of the filter cake is too highConversely, if the feed pressure is too small, the solid particles in the material will not be fully pressed, so that the dryness of the filter cake will be reduced. Therefore, in the process of filter pressing, the feed pressure should be reasonably adjusted to obtain the best filtration effect.
3. Improper selection of filter cloth.
Different materials need to choose different materials and pore sizes of filter cloths. If the pore size of the filter cloth is too large, the solid particles in the material will not be effectively retained, so that the dryness of the filter cake will be reducedOn the contrary, if the pore size of the filter cloth is too small, it will lead to an increase in filtration resistance, which will easily cause the filter cloth to clog and further reduce the dryness of the filter cake. Therefore, when selecting filter cloth, a reasonable choice should be made according to the characteristics of the material and the filtration requirements.
Fourth, improper washing methods.
During the filter press process, the choice of washing method also affects the dryness of the filter cake. If the washing method is improper, the washing water will not be evenly distributed on the surface of the filter cake, so that the moisture in some areas cannot be fully removed, affecting the dryness of the filter cake. Therefore, the appropriate washing method should be selected according to the actual situation, such as using sectional washing, strengthening the distribution of washing water, etc., to improve the dryness of the filter cake.
5. Improper equipment maintenance.
Routine maintenance and upkeep of the filter press is essential to maintain the performance of the equipment and extend its lifespan. If the equipment is not properly maintained, such as not cleaning and replacing the filter cloth and other wearing parts in time, it will lead to the degradation of equipment performance and poor filtration effect, which will affect the dryness of the filter cake. Therefore, the filter press should be regularly maintained and maintained to ensure its normal operation.
6. Improper operation.
The technical level and experience of the operator directly affect the operation of the filter press. If the operator is not familiar with the performance of the equipment and the operating procedures, it is easy to make mistakes or improper operation in the filtration pressing process, resulting in the dryness of the filter cake does not meet the requirements. Therefore, it is necessary to strengthen the training and technical disclosure of operators to improve their operation level and sense of responsibility.
To sum up, the reasons why the filter cake of the filter press is not dry enough mainly include the quality of the filter cloth is not up to standard, the feed pressure is improper, the filter cloth is not properly selected, the washing method is improper, the equipment is not properly maintained, and the operation is improper. In order to improve the work efficiency and filtration effect of the filter press and obtain a drier filter cake, corresponding measures need to be taken according to the actual situation.
