How to make filter press filter cloth and filter press fit better?
October 09, 2021
All filter press equipment is a kind of filtration equipment that carries out solid-liquid separation of the mixed liquid. The components of the equipment are processed from metal materials and plastic materials, which cannot be separated from the mixed liquid. Therefore, the filter press equipment needs the assistance of the filter press filter cloth to realize its actual function.
Therefore, the use of filter press equipment has to use a variety of filter cloth filter cloth, and now the filter press equipment, its gap type filter press occupies more than 80% of the market share, so in the filter press application process It will inevitably lead to the problem of replacing the filter cloth. Today we will solve such a problem: how to change the filter cloth and filter equipment to better match?
The first is to choose a filter cloth. Choose the filter cloth that is suitable for the filter press equipment. In addition to not only selecting the type of filter cloth, the size of the filter cloth, and the number of meshes of the filter cloth, we often choose the preparation of the filter cloth. The properties of the cloth such as temperature resistance or ductility. For example, for some viscous viscous liquids, we can choose a diagonal filter cloth, which improves the contact between the filter cake and the filter cloth surface, which makes it easier to separate the filter cake from the filter cloth. This will facilitate the filter press and filter. Better fit between the cloths.
Second, the placement of the filter cloth. Choosing the type of filter cloth suitable for your own filter press equipment is how to place the filter cloth on the filter press. During the placement process, the filter cloth needs to be placed flat between the filter and the filter plate. Note that there can be no wrinkles, which will increase the difficulty of sealing the filter room of the filter press, which will result in a decrease in the quality of the filter press. Care must be taken not to overtighten the filter, causing tearing of the filter cloth, because the horizontal filter press will store the filter cake in the filter chamber between the filter cloth and the filter cloth. Too tight, as the filter cake builds up, it will burst the filter cake.
Thirdly, the washing and storage of filter cloths are mainly focused on washing. After a suitable period of time, the filter cloths often have a certain influence on the filtration efficiency and quality, so it is necessary to wash the filter cloths. During the washing process, try to apply some weak weak acid or weak alkaline solution to wipe the surface of the filter cloth until the surface of the particulate solids is softened, rinse with water, and use the constant force to move.
As long as these three points are achieved, the filter cloth and the chamber filter press can be perfectly matched, and the filter press can be applied to more perfect work.
