In modern industrial production, the longest used solid-liquid separation equipment - filter press, this equipment can work normally, it is not possible to have mechanical equipment, and the filter cloth is needed, then the filter press and filter What is the relationship between cloth? What is the specific working principle? The whole set of equipment principle of the filter press: the mixed liquid is sent out and pressed by the feed pump, so that the mixed liquid is evenly fed into the filter press equipment, and the pipeline of the feed pump is connected with the feed valve of the equipment. When the mixed liquid is poured into the device, it flows into the filter chamber of the filter chamber of the device design, which is really close to the contact between the filter plates. Incidentally, such a total area in contact with the filter cloth is the actual use area of ​​the filter press, that is, the effective area. It seems that the two are inextricably linked. There is a complete set of filter press equipment and a lack of filter cloth. Even if it provides strong pressure, the mixture cannot separate the solid and liquid. This lacks the selective separation of the filter cloth. If there is only a filter cloth, even if its mixture is in good contact, the separation effect cannot be achieved, and the liquid does not bleed out from the filter portion, and the pressure of the liquid on the liquid is not provided, and the kinetic energy cannot be provided for the liquid.
When the mixture is in contact with the filter cloth, the chamber filter press equipment must provide an important condition - a pressure difference is formed on both sides of the filter cloth, and the mixture is squeezed, and the filter cloth is applied to the solid. Obstruction. Sum of the above conditions, so that the filter press achieves the interception of solids, accumulated on the filter cloth to form a filter cake, the pressure difference provides a source of continuous power for the liquid to seep through the filter plate.
