Mechanical filter press filter cake expansion will cause the filter cloth to shrink into the filter plate
The filter cloth is retracted between the filter plates: for the mechanical filter press, to filter the normal work, it must be ensured that the two sides of the filter cloth must form a separate space, so the filter cloth must be required. The edge is pressed on the edge of the filter cloth, and the filter cloth is often larger than the filter plate. Generally, it is afraid that the mechanical filter press is in the process of working, and the filter cake is expanded, so that the filter cloth is retracted into the filter plate, so that the filter cloth is equivalent. When it broke, it naturally appeared.
The mesh size of the filter cloth is too small: the mesh number is an important parameter for the filter cloth. It indicates the size of the filter hole that the filter cloth has. When the mesh size is smaller, it indicates that the filter cloth has a filter hole. The larger the filter hole is, the larger the solids need to be intercepted, the more solid particles pass through the filter cloth in the normal way, resulting in the turbidity of the filtered liquid.
Cracking of the filter cloth: We all know that the filter cloth is generally woven from various fibers, just like the cloth, so the filter cloth is soft and malleable. It is because of this, how the filter cloth is in the dry work, or In the storage, it is easy to damage the filter cloth, such as being pierced by a hard object, such as being broken by a filter cake, etc. When the filter cloth is broken, when the mechanical filter press is running, there will be a large amount of The solid passes through the filter cloth from the rupture, and flows out of the equipment through the drainage system of the equipment. The liquid filtered by the natural mechanical filter press still appears turbid.
