What principles are needed to match the filter cloth of the frame filter press

      Talking about the knowledge of belt filter press what principles are needed to match the filter cloth of the frame filter press.

Matching frame filter press filter cloth needs the following five principles to support:

1. According to the chemical and physical properties of the material, select the filter cloth material. The supplier of the filter cloth provides as much detailed technical information as possible, please choose the permeability requirements of the filter cloth according to the precision filter;
2. Technical parameters such as preliminary selection of reserved size. Although the filter cloth of the initial filter press has played an important role in the filtration accuracy, the initial filtration accuracy does not consider the possibility that the filtration accuracy can reach lower requirements as much as possible. In a period of news due to the formation of the filter layer, the filter has negated the role of a small cloth, and really played the role of a filter that is not fine enough to form a “filter layer” to form a good filter press layer is the key to the use of technology;
3. Pay attention to the peeling performance when choosing filter cloth. The surface of the cloth is smooth, the cake is peeled quickly, the operation time of thorough filtration is short, and the efficiency is high. This cake is not easy to peel off the adhesion of the filter cloth, the filter press will extend the open time and reduce the work efficiency. To replace the filter cloth, it will take longer. Now it has been widely used in chamber filter presses, and filter cloth replacement is more troublesome. Choosing multifilament than long and short fiber cloth cake discharge performance is better than plain satin cloth cake discharge performance, choosing filter cloth is better;
4. Regeneration performance of filter cloth. It performed well when choosing filter cloth, and paid attention to the choice of renewable filter cloth. The filter cloth of the regenerative filter press has good performance and can be wiped directly with a towel to reduce the amount of cloth changed. Replace the filter cloth through a simple process, and the filtration efficiency is 80%;
5. Experiment of filter material. The use of filter press technology is an experimental technique. After the filter cloth, the initial filtration experiment of selecting raw materials is very important. Experiment with a sample of filter material. Filter cloth inspection rate, retention effect, filter cake moisture, discharge performance and reuse performance.
